Description

  The present invention relates to a biological information measurement system, and more particularly to a biological information measurement system that measures the physical condition of a subject based on defecation gas discharged into a bowl of a toilet bowl installed in a toilet room.

  In recent years, with the advancement of medical technology, the mortality rate due to cancer has become extremely low due to the diagnostic technology for major diseases such as cancer and the technological evolution of cancer treatment itself. However, it is a burden for patients to go to the hospital to receive regular diagnosis for cancer prevention. For this reason, in reality, there are many patients who come to the hospital after realizing a poor physical condition, and unfortunately, there are still many people who get cancer. In addition, a practical device for suppressing the occurrence of cancer has not been developed yet, and in reality, it cannot be said to be sufficient for realizing cancer prevention.

  In view of such a situation, the present inventors have made a device that can more easily diagnose major illnesses such as cancer at home without going to the hospital, and can really prevent major illnesses or realize early treatment. He had a strong desire to manufacture the equipment required by the market, and he had been researching for a long time.

  Until now, the applicant has collected the defecation gas that is mounted on the toilet seat of a Western-style toilet and is discharged into the bowl when the subject defecates, and based on the concentration of carbon dioxide contained in the defecation gas, A device for obtaining the amount of excreted stool (see Patent Document 1) and a deodorizing device incorporated in the toilet seat of the flush toilet are sucked with a deodorizing device that is combined with the subject's stool, and the carbon dioxide concentration of the sucked gas is determined by carbon dioxide. An apparatus (see Patent Document 2) that estimates the intestinal state of a subject based on a gas sensor and based on the measured carbon dioxide concentration has been developed. However, these devices only estimate the current state of the intestine, and have not achieved the inventor's purpose of easily diagnosing a major disease such as cancer and grasping the risk status thereof. Furthermore, a fart detection device (Patent Document 3) is also known in which a gas sensor is disposed so as to come into contact with the air in the vicinity of a human excretion portion, and a fart is detected based on the peak value of the gas sensor output. In this fart detection device, the fart of the patient is collected by pulling out the tube from the excretion part in the diaper or underwear of the patient sleeping on the bed and sucking air with a suction pump. Furthermore, this fart detection device distinguishes farting from urination based on the half-value width of the peak of the gas sensor output, and the doctor confirms whether a fart has come out after cecal surgery or detects when to change diapers However, it does not achieve the purpose of the inventor. On the other hand, in Japanese Patent Application Laid-Open No. 2014-160049 (Patent Document 4), a sensor for measuring methyl mercaptan gas from a soot component released by a subject, a calculation unit for calculating a methyl mercaptan gas concentration obtained from the sensor, and a display A portable colorectal cancer risk measuring device for estimating the risk of developing colorectal cancer is known.

Japanese Laid-Open Patent Publication No. 9-43182 (Patent Document 5) describes a biological monitor device. In this living body monitor device, a gas sensor is attached to a T-band made of cloth so that the gas sensor is disposed in the vicinity of the anus, and a fart discharged from the anus is detected. The signal from the gas sensor is transmitted to the processing device and stored in the memory. It is also known that data stored in a memory is compared with past data, and a warning is displayed on a display device when there is an abnormality such as when the difference is large.
Japanese Patent No. 3525157 (Patent Document 6) describes an intestinal gas component measurement method. In this intestinal gas component measurement method, a sampling tube is arranged in the toilet seat portion of the toilet bowl. When the person to be measured turns on the main switch of the apparatus, the suction pump is operated and the gas near the anus is sucked. The indicator gas detector constantly measures the concentration of carbon dioxide in the sucked gas, and when the measured concentration rapidly increases, the control / arithmetic processing unit recognizes that intestinal gas has been diffused. When the intestinal gas is released, another suction pump begins to operate, and a portion of the sucked gas is taken into the sample metering tube. The taken sample is sent to the column to separate the gas components and to be ionized. It is also known that the ionization amount is converted into an electric signal and the concentration of the detection target gas component in the intestinal gas is measured.
Japanese Unexamined Patent Application Publication No. 2014-206945 (Patent Document 7) describes a health information utilization system. In this health information utilization system, personal health information related to health management input from a terminal device is stored separately in a plurality of data center databases, and the analysis server device reads and analyzes the personal health information. The big data creation server device searches for personal health information under specific conditions, and creates and stores big data. Health information utilization system allows health contents based on knowledge in specialized fields to be browsed on terminal devices, stores and manages personal health information in multiple data centers, and health judgment results obtained by automatically judging personal health information Or, the health determination result determined by the expert is browsed on the terminal. Such things are also known.

  In developing a device capable of diagnosing such a major disease such as cancer, it has been known in recent years that there is a correlation between a disease of colon cancer and gas components in the intestine contained in a fart or defecation. ing. Specifically, colon cancer patients have more methyl mercaptan gas containing sulfur components in gas components in the intestine than healthy individuals.

Japanese Patent No. 5131646 Patent No. 5019267 JP 2003-90812 A JP 2014-160049 JP 9-43182 A Japanese Patent No. 3525157 JP 2014-206945 A

  The gas component in the intestine is discharged as a fart or defecation gas together with the stool during defecation. Therefore, as described in the Nihon Keizai Shimbun on January 5, 2015, the inventors identified a fart discharged at the time of defecation and methyl mercaptan gas in the defecation gas as in the case of the above-mentioned Patent Document 4 and the like. I was able to detect colorectal cancer in the intestine by measuring the amount of gas. However, a measuring apparatus that can accurately measure only a specific gas such as methyl mercaptan gas is very expensive and large. In addition, the amount of methyl mercaptan gas contained in the defecation gas is very small, and it is very difficult to measure because it becomes a very small amount at the stage before cancer. At least such a gas analyzer that can measure accurately is used at home. The inventors faced the problem that it was not very realistic to install it in a toilet device and spread it as a consumer product, both in terms of cost and size.

  However, the inventors want to reduce the number of people who become seriously ill such as cancer. To that end, we continued research with the very strong desire that general consumers need to make a device that can be easily purchased and diagnosed easily at home, and finally found a technical solution for its realization. is there.

  The object of the present invention is to prevent general consumers from easily purchasing and measuring serious illnesses such as cancer by measuring fecal gas at home, or going to a hospital in a mild condition for treatment. It is to provide a highly practical diagnostic system that can be urged to be received and is truly required by the market.

  In order to solve the above-described problems, the present invention is a biological information measurement system for measuring the physical condition of a subject based on the defecation gas discharged into the bowl of the flush toilet, wherein the defecation gas is discharged by the subject. A suction device that sucks the gas in the bowl, and a gas sensor that reacts with odorous gases other than methyl mercaptan gas and methyl mercaptan gas, which are contained in the gas sucked by the suction device and contain sulfur components Detected by the gas detection device, the stool state detection sensor for detecting the state of the stool discharged into the bowl, the suction device, the gas detection device, the control device for controlling the stool state detection sensor, and the gas detection device Analyzes the physical condition of the subject based on the detection data on the odorous gas in the defecation gas and the stool state detected by the stool state detection sensor A data analysis device and an output device for outputting an analysis result by the data analysis device, and the data analysis device stores a stool state detected by a stool state detection sensor over time. An analysis result correction unit that corrects the result of the gas physical condition analysis based on the detection data relating to the odorous gas based on the stool state stored in the stool state storage device, and is corrected by the analysis result correction unit. The result of the gas physical condition analysis is output by an output device.

  Conventionally, there has been no actual device for confirming whether a major illness such as cancer, or confirmation for the prevention of a major illness exists other than diagnosis at a hospital. On the other hand, according to the present invention, a general consumer can easily purchase a subject-side device and measure it at home. In addition, because it measures the defecation gas discharged during defecation, the subject does not have to bother to perform a new measurement act, and simply perform the excretion action that is performed daily, resulting in a serious disease such as cancer. Can be prevented in advance, or can be treated by visiting a hospital in a mild condition. As described above, according to the present invention, it is possible to realize an apparatus that is truly required from the market and to provide a highly practical diagnostic system.

  Here, before specifically explaining the effects of the present invention, a technical concept that enables a system that can be spread as a consumer product in a general household will be described. The key points lie in the idea of reversal and the knowledge of effective divestiture using the characteristics of major diseases such as cancer.

  Specifically, one of the key points of the system of the present invention is the idea of reversal that the subject side device installed in each home does not diagnose a major illness such as cancer. In other words, the subject who is a general consumer who purchases the subject-side device does not want to know that he / she has cancer, but the risk of cancer is increasing at the stage before becoming cancer (hereinafter this stage is referred to as non-disease). Really, I really want to improve my life so that I don't get cancer. In other words, the device required for general households is thought to be valuable only in that a healthy person can accurately grasp cancer risk and improve physical condition so as not to get cancer.

  Next, one of the key points of the system of the present invention is a device for diagnosing a specific type of cancer such as a specific rectal cancer, or a device capable of diagnosing an increased risk of a specific type of cancer. It is in the dilemma that it is not. This is because the subject is not worried about a particular type of cancer, such as rectal cancer, but is worried about any cancer. Therefore, the inventors do not have a commercial value unless a specific type of cancer is diagnosed, and think that there is no need for accuracy to specify the type of cancer, and can specify the type of cancer. It was decided that such measurement accuracy was unnecessary.

  Next, one of the key points of the system of the present invention is the divisor that diagnosis accuracy for each excretion may be extremely low. This is based on the idea that cancer is a disease that progresses over a long period of several years, and we realize that the chance of diagnosis extends over a long period of years. Therefore, if it is positioned as a device for reducing the risk that healthy people will get cancer, it will be noticed that there is virtually no problem even if the diagnostic accuracy is low once, and it is effective based on this. One of the keys is the regular cleaving.

Hereinafter, the specific effect of the system based on this invention constructed | assembled based on these knowledge and effective crevice is demonstrated.
In the present invention, since the subject's physical condition is analyzed by measuring the defecation gas discharged into the bowl of the toilet bowl, there is no need for the subject to bother to perform a measurement act, and defecation performed simply every day is usually performed. Diagnosis can be made simply by doing. In addition, since there is no hassle at all, the subject is not burdened, and measurement can be continued for a long period of time, so that information on changes in health status and a situation in which cancer risk is increased can be obtained with certainty.

  Further, in the present invention, a sensor that reacts widely with odorous gases other than methyl mercaptan gas in the defecation gas is used without using a sensor that measures methyl mercaptan gas at a pinpoint. When a sensor that measures methyl mercaptan gas in a pinpoint manner is used, it can be reliably detected that there is a correlation between the amount of methyl mercaptan gas and colorectal cancer, and the risk of cancer has increased. Is definitely known from the amount. However, this increases the risk of cancer to some extent, and if the amount of methyl mercaptan gas does not increase, it cannot be determined that the risk of cancer is increased, and is not suitable for the present invention for the purpose of preventing cancer. I realized that.

  On the other hand, in the case of a sensor that reacts widely with odorous gas, it can be detected not only from an increased cancer risk but also from a poor physical condition. Specifically, in a state where the risk of cancer has increased, a very strong odorous gas containing a sulfur component such as methyl mercaptan gas or hydrogen sulfide increases. And if it is a sensor which reacts widely with odorous gas, such an increase in gas can be detected without fail.

  Further, in the present invention, not only methyl mercaptan gas, but also a gas detection device that reacts to odorous gas in stool gas other than methyl mercaptan gas, only the amount of odorous gas in stool gas is known, The amount of methyl mercaptan gas cannot be measured, and the cancer state cannot be accurately identified. However, the inventors use a gas detection device that reacts not only with methyl mercaptan gas but also with odorous gas in defecation gas other than methyl mercaptan gas, so that healthy people have an increased risk of cancer. It has been found that it functions effectively as a device for preventing the risk of cancer and the risk of developing cancer. Specifically, a healthy person has a low total amount of odorous gases other than methyl mercaptan gas and methyl mercaptan gas. On the other hand, the total amount of odorous gases other than methyl mercaptan gas and methyl mercaptan gas temporarily increases due to deterioration of the intestinal environment, as well as cancer. Specifically, the deterioration of the intestinal environment is a deterioration of the intestinal environment due to factors such as excessive constipation, types of meals, lack of sleep, excessive drinking and overeating, excessive drinking, and excessive stress. However, all these factors are bad lifestyle habits. Cancer develops after bad lifestyle habits, but until now, even if the risk of cancer has risen, there is no way to recognize it, and as a matter of fact, many people now have a bad life with a good belief that they are all right Continuing customs.

  As described above, when bad lifestyle habits as described above are performed, all or any of the odorous gases in the defecation gas such as methyl mercaptan, hydrogen sulfide, acetic acid, trimethylamine, and ammonia increases. In contrast, the present invention is based on detection data of a gas detection device that detects not only methyl mercaptan gas but also odorous gas in stool gas other than methyl mercaptan gas such as hydrogen sulfide, acetic acid, trimethylamine, and ammonia. Is being analyzed. For this reason, the analysis results based on the total amount of odorous gas in the defecation gas reflect the results of the subject's poor physical condition and bad lifestyle habits, and the analysis results are based on physical conditions and lifestyle habits that increase the risk of such cancer. It can be used as an index based on objective data for improving cancer, that is, as an effective index for maintaining health and reducing the risk of developing cancer. For the purpose of improving lifestyle and suppressing cancer risk It has been found that it is an excellent effect that works extremely effectively.

  As described above, according to the present invention, methyl mercaptan gas and odorous gas other than methyl mercaptan gas are measured, so that the cancer risk is in an increased state, and such a state is continued for a long time. The measurement which can notify a test subject of the suitable alarm which will become cancer is attained. The inventors have found a suitable finding for the purpose of reducing the number of people who become cancerous by the so-called reversal idea.

  Furthermore, according to the present invention, since a sensor that reacts widely with not only methyl mercaptan gas but also odorous gas other than methyl mercaptan gas is used, the apparatus can be manufactured at low cost and provided as a consumer product. It became possible. This makes it possible for the subject to easily diagnose at home, prevent a serious illness such as cancer from occurring, or to promptly go to the hospital and receive treatment in a mild condition. It was able to meet the requirements sufficiently.

  On the other hand, in the present invention, since a sensor that reacts widely with not only methyl mercaptan gas but also odorous gas other than methyl mercaptan gas is used, measurement accuracy is improved by odorous gas derived from gas other than the defecation gas of the subject. May decrease. Further, in an unill-treated state before a serious disease such as cancer, the amount of odorous gas in the defecation gas may not increase so much. Here, in an unaffected state prior to colorectal cancer, or in patients with colorectal cancer, the number of defecation actions per day increases, the stool becomes shredded, and the amount of defecation in a single excretion decreases. The inventor found that there is a tendency for defecation abnormalities to occur. According to the present invention configured as described above, the analysis result correcting unit corrects the result of the gas physical condition analysis based on the detection data regarding the odorous gas based on the stool state over time stored in the stool state storage device. doing. For this reason, according to the present invention, it becomes possible to compensate for the weakness of the gas physical condition analysis that the measurement accuracy decreases due to the use of a general-purpose odorous gas sensor and the odorous gas does not increase so much in an unaffected subject. The reliability of the analysis result can be further improved.

  In the present invention, preferably, it further has a stool state analysis means for performing a stool state physical condition analysis based on a stool state detected by a stool state detection sensor, and the data analysis device includes a stool state along with a result of the gas state analysis The result of the physical condition analysis is output by the output device.

  According to the present invention configured as described above, the bad lifestyle habits of the subject are reflected in the result of the fecal state physical condition analysis, and this is output by the output device, thereby prompting the subject to improve life early. , Can effectively reduce the risk of suffering from a major illness.

In the present invention, preferably, the result of the gas physical condition analysis and the result of the fecal state physical condition analysis are notified by the output device so that the change over time of the result of each physical condition analysis can be recognized.
According to the present invention configured as described above, the result of the gas physical condition analysis and the result of the fecal state physical condition analysis are notified so that the change over time of the result of each physical condition analysis can be recognized. It is possible to present the analysis result in an easy-to-understand manner even for poor subjects. In addition, since changes over time are reported in a recognizable manner, it is possible to comprehensively present to the subject an increased risk of illness from both the defecation gas and stool state, and the subject can reliably take measures to improve physical condition. It becomes possible to do.

  In the present invention, preferably, the stool state storage device has, as the stool state, the number of defecation actions per day of the subject, the total amount of defecation during one defecation period of the subject, the amount of defecation during one excretion of the subject, The frequency at which the subject becomes constipated and / or the frequency at which the subject becomes loose stool is stored.

  According to the present invention configured as described above, the number of defecation behaviors per day of the subject, the total amount of defecation during one defecation period of the subject, the amount of defecation during one excretion of the subject, and the subject becomes constipated Since the frequency and / or the frequency at which the subject becomes loose stool is analyzed as a stool state, stool abnormalities when suffering from colorectal cancer, etc. can be reliably captured, and the weakness of gas physical condition analysis is compensated for with higher accuracy Physical condition measurement can be realized.

  In the present invention, preferably, the analysis result correcting means is based on the stool state over time after the stool state data detected by the stool state detection sensor is accumulated in the stool state storage device for a predetermined accumulation period or longer. Correct the result of gas condition analysis.

  When short-term bowel movement abnormalities occur, correcting the results of gas physical condition analysis based on stool status data to warn of an increased risk of major illness is likely to be a false warning and is unnecessary for the subject. The result is psychological anxiety. According to the present invention configured as described above, after the stool state data is accumulated for a predetermined accumulation period or more, the result of the gas physical condition analysis is corrected. Can be prevented and unnecessary psychological anxiety can be prevented.

  In the present invention, preferably, the analysis result correcting means starts correction of the result of the gas physical condition analysis after the fecal state data has been accumulated for the accumulation period or longer, while the fecal state analyzing means has the fecal state data The feces state physical condition analysis is executed even in a state where the data is not stored, and the data analysis apparatus causes the output device to output the result of the fecal state physical condition analysis.

  Even if the change in the stool state is short-term, it is useful information for the subject to know the daily physical condition. According to the present invention configured as described above, the result of the stool condition analysis is output even when the stool condition data is not accumulated, and the stool condition data is accumulated for the correction of the gas condition analysis result. The test subject can recognize the daily health condition early while preventing the occurrence of unnecessary psychological anxiety.

  In the present invention, preferably, the data analysis device performs the gas physical condition analysis based on the detection data at the first excretion in the defecation period, while the stool state analysis means applies the entire defecation period detected by the stool state detection sensor. A stool state physical condition analysis is executed based on the stool state.

  According to the present invention configured as described above, since the fecal state is detected, the physical condition can be measured with sufficient accuracy even if the target of the gas physical condition analysis is limited to the detection data at the first excretion. In addition, by targeting only the detection data at the time of the first excretion, it becomes possible to display the analysis result of the physical condition at the end of the defecation period by the subject, and the practicality of the biological information measurement system can be improved.

  In the present invention, preferably, the data analysis apparatus selects detection data used for gas physical condition analysis using detection data from the stool state detection sensor from detection data related to odorous gas detected during the defecation period. To do.

  Of the defecation gas discharged from the subject, a fart that is excreted without stool is useful for gas health analysis because the concentration of methyl mercaptan gas and the like contained therein is high and the amount of gas is large. According to the present invention configured as described above, since the stool state is detected by the stool state detection sensor, it is possible to reliably identify the defecation gas accompanied by the fart and the stool, and for the gas condition analysis Useful odorous gas detection data can be reliably selected.

  In the present invention, preferably, the analysis result correcting means corrects the result of the gas physical condition analysis by increasing the correction amount based on the fecal state when the result of the gas physical condition analysis is deteriorated to a predetermined physical condition level or more. Run.

  In the gas physical condition analysis based on odorous gas, after the subject's physical condition level deteriorates to some extent, the analysis accuracy of the physical condition tends to decrease. According to the present invention configured as described above, when the result of the gas physical condition analysis is deteriorated beyond a predetermined physical condition level, the correction amount based on the fecal state is increased with respect to the result of the gas physical condition analysis. It is possible to accurately report the risk of disease. In addition, since the stool state is easier for the subject to recognize than the gas physical condition analysis based on the odorous gas, the subject can easily recognize the increase in morbidity risk, and the subject can be effectively promoted to improve the physical condition.

  In the present invention, preferably, the analysis result correcting means corrects the result of the gas physical condition analysis by increasing the correction amount based on the fecal condition when the result of the physical condition analysis deteriorates to a predetermined physical condition level or more. Execute.

  According to the present invention configured as above, when the result of the stool state physical condition analysis is deteriorated to a predetermined physical condition level or more, the correction amount based on the stool state is increased with respect to the result of the gas physical condition analysis. It is possible to accurately report the risk of disease.

  In the present invention, preferably, the stool condition analyzing means is configured to determine the result of the stool condition physical condition analysis as a plurality of stages of physical condition levels, and the analysis result correcting means is set to the physical condition level determined by the stool condition analyzing means. Accordingly, the correction amount for the gas physical condition analysis result is changed in a plurality of stages.

  The stool state also changes depending on the food intake and temporary physical condition. According to the present invention configured as described above, the stool state analyzing unit determines the result of the stool state physical condition analysis as a plurality of stages of physical condition levels, and the analysis result correcting unit has the physical condition level determined by the stool state analyzing unit. Accordingly, the amount of correction for the results of the gas physical condition analysis is changed in multiple stages, so it is possible to evaluate and correct the physical condition level finely, suppressing the unnecessary psychological burden on the subject while increasing the disease risk. It is possible to reliably notify.

  In the present invention, preferably, the analysis result correcting unit is configured to represent the result of the gas physical condition analysis based on the current measurement based on a plurality of predetermined reliability levels, and the history representative value representing the result of the plurality of past gas physical condition analyses. The analysis result correction means is configured to perform correction so that the result of gas physical condition analysis based on the current measurement is close to the history representative value based on the stool state detected by the stool state detection sensor. To improve reliability.

  As described above, in the gas physical condition analysis, the measurement accuracy for each time is not high. For this reason, the past history correction is performed so as to bring the result of the gas physical condition analysis based on the current measurement closer to the historical representative value representing the results of the plurality of past gas physical condition analyses, thereby giving an unnecessary psychological burden to the subject. It has become possible to effectively detect an increase in disease risk over time. According to the present invention configured as described above, the past history correction amount that brings the result of the gas physical condition analysis based on the current measurement closer to the history representative value is changed based on the stool state detected by the stool state detection sensor. Therefore, it is possible to more reliably detect an increase in disease risk over time without greatly complicating the analysis system.

  In the present invention, preferably, it further includes a subject specifying device for specifying the subject and the measurement date and time, and the output device can transmit the result of the gas physical condition analysis and the result of the fecal state physical condition analysis together with the measurement date and time for each subject. It is configured.

  According to the present invention configured as described above, the result of the gas physical condition analysis and the result of the fecal state physical condition analysis are transmitted for each subject together with the measurement date and time, so that the past individual detection data is accurately transmitted to a doctor or the like.

Hereinafter, an embodiment of a biological information measurement system of the present invention will be described in detail with reference to the drawings.
Moreover, FIG. 1A is a figure which shows the state which attached the biological information measuring system by 1st Embodiment of this invention to the flush toilet installed in the toilet room. FIG. 1B is a cross-sectional view of a flush toilet equipped with a biological information measurement system. FIG. 2 is a block diagram showing a configuration of the biological information measurement system of the present embodiment. FIG. 3 is a diagram illustrating a configuration of a gas detection device provided in the biological information measurement system of the present embodiment.

  As shown in FIG. 1A, the biological information measurement system 1 includes a measuring device 6 incorporated in a toilet seat 4 placed on a flush toilet 2 installed in a toilet room R, and a wall surface of the toilet room R. It has a subject-side device 10 consisting of an attached remote control 8. Furthermore, as shown in FIG. 2, the biological information measuring system 1 includes a server 12, a subject terminal 14 incorporating dedicated software in a smartphone, a medical institution terminal 16 installed in a medical institution such as a hospital, These perform part of the functions of the biological information measurement system 1 by exchanging data with the subject-side device 10. The server 12 and the medical institution terminal 16 accumulate measurement data transmitted from a large number of subject-side devices 10 and perform data analysis.

In the biological information measurement system 1 of the present embodiment, the physical condition state including the determination of cancer based on odorous gas containing sulfur component in the defecation gas released by the subject during defecation, particularly methyl mercaptan (CH ₃ SH) gas. Analyze. Furthermore, in the biological information measuring system 1 of the present embodiment, in addition to odorous gas, the health gas and the amount of defecation are measured, and based on these, the analysis accuracy of the physical condition is improved. The health-related gas is a gas derived from intestinal fermentation and increasing as the intestinal health level increases, and specifically, is a gas such as carbon dioxide, hydrogen, methane, and short chain fatty acid. In the present embodiment, carbon dioxide gas and hydrogen gas that can maintain high reliability of the health index measurement are measured as the health gas because it is easy to measure and has a large amount. Here, each subject apparatus 10 is configured to display the analysis result during or immediately after the subject's stool. On the other hand, in the server 12, measurement results from a large number of subjects are accumulated, and a more detailed analysis is possible by comparison with other subjects. As described above, in the biological information measuring system 1 of the present embodiment, simple analysis is performed in the subject-side apparatus 10 installed in the toilet room R, and more detailed analysis is performed in the server 12.

Here, the measurement principle of the physical condition in the biological information measurement system 1 of the present embodiment will be described.
It is reported in the literature that odorous gas containing sulfur components such as methyl mercaptan and hydrogen sulfide is discharged simultaneously with defecation from affected areas when suffering from cancer of the digestive system, particularly colorectal cancer. The digestive organs are the esophagus, stomach, duodenum, small intestine, large intestine, liver, pancreas, and gallbladder. The large intestine can also be classified into the appendix, cecum, rectum, and colon. . Cancer has little change every day and progresses gradually. As cancer progresses, the amount of odorous gas containing sulfur components, particularly methyl mercaptan, increases. That is, when the amount of odorous gas containing a sulfur component increases, it can be determined that cancer is progressing. Furthermore, in recent years, the idea of “non-disease” has spread, and the idea of improving the physical condition and preventing the disease when the physical condition deteriorates before becoming a diseased condition has spread. For this reason, it is required to detect cancer, particularly advanced cancer such as colorectal cancer, and improve physical condition before becoming cancer.

  Here, in addition to hydrogen sulfide and methyl mercaptan, defecation gas excreted during defecation includes nitrogen, oxygen, argon, water vapor, carbon dioxide, hydrogen, methane, acetic acid, trimethylamine, ammonia, propionic acid, methyl disulfide, three Contains methyl sulfide. Among these, in order to determine a cancer disease, it is necessary to measure an odorous gas containing a sulfur-based component, particularly methyl mercaptan. Propionic acid, methyl disulfide, and trifluidized methyl contained in the defecation gas are very small amounts compared to methyl mercaptan, and can be ignored because they do not pose any problem for analysis of physical condition such as cancer determination. However, other gas components are not so small as to be negligible. In order to accurately determine cancer, it is naturally conceivable to use a sensor that can detect only odorous gas containing a sulfur component. However, since a sensor that detects only odorous gas containing a sulfur component is large and very expensive, it is difficult to configure it as a household device.

  In contrast, as a result of earnest research, the inventors have not only detected methyl mercaptan in the defecation gas, but by using a gas sensor that detects odorous gas including other odorous gas, it is cheaper. The idea was that it could be configured as a household device. Specifically, the inventors use a general-purpose semiconductor gas sensor or solid electrolyte sensor that reacts not only with a sulfur-containing gas containing a sulfur component but also with other odorous gases as a sensor for detecting gas. It was.

  In a state where the risk of cancer is increased, a very strong odorous gas containing a sulfur component such as methyl mercaptan gas is increased. And if it is a sensor which reacts widely with odorous gas like a semiconductor gas sensor and a solid electrolyte sensor, such an increase in gas can be detected without fail. However, as will be described later, sensors that react widely with odorous gases such as semiconductor gas sensors and solid electrolyte sensors, such as hydrogen sulfide, methyl mercaptan, acetic acid, trimethylamine, and ammonia that increase when they become unwell due to bad lifestyles. Odor gas is also detected. However, cancer is a disease that progresses over a long period of several years, and in the case of cancer, a state in which a very strong odorous gas containing a sulfur component such as methyl mercaptan gas or hydrogen sulfide is strengthened. It will last for a long time. Therefore, even if a general-purpose semiconductor gas sensor or solid electrolyte sensor that reacts not only with sulfur-containing gases containing sulfur components but also with other odorous gases is used, Therefore, it can be determined that the risk of cancer is high and the risk of cancer is increasing.

  In addition, semiconductor sensors and solid electrolyte sensors using oxidation / reduction reactions detect not only methyl mercaptan gas but also odorous gases such as acetic acid, trimethylamine, and ammonia in the defecation gas. However, as a result of experiments, the inventors have found that the amount of mixed odorous gases such as hydrogen sulfide, methyl mercaptan, acetic acid, trimethylamine, and ammonia increases when the physical condition deteriorates due to bad lifestyle, and the physical condition is good. It was found to show a decreasing trend. Specifically, a healthy person has a small total amount of odorous gases other than methyl mercaptan gas and methyl mercaptan gas. In contrast, the total amount of methyl mercaptan gas and other odorous gases other than methyl mercaptan gas is the amount of intestinal environment due to excessive constipation, types of meals, lack of sleep, overdrinking, excessive drinking, excessive drinking, and excessive stress. Temporarily increases due to deterioration.

The acetic acid in the defecation gas tends to increase not only when the physical condition deteriorates due to diarrhea or the like but also when the physical condition is good. That is, it does not necessarily coincide with the tendency of the amount of other odorous gases such as methyl mercaptan accompanying the above-described physical condition change. However, the amount of acetic acid contained in the defecation gas is very small compared to methyl mercaptan, and even if the amount of acetic acid increases when the physical condition is good, the increase is the decrease in other odorous gases. Very small compared to Furthermore, the increase amount of acetic acid when the physical condition deteriorates due to diarrhea or the like is much larger than the increase amount when the physical condition is good. Therefore, as a whole, the amount of odorous gas contained in the defecation gas increases when the physical condition deteriorates due to bad lifestyle, and tends to decrease when the physical condition is good. And since the intestinal environment deteriorates due to such bad lifestyle habits, it becomes cancer, so the amount of odorous gas contained in the defecation gas improves the physical condition while the cancer is unaffected Therefore, it becomes a suitable index.
In this embodiment, not only methyl mercaptan gas but also physical condition based on detection data of semiconductor sensors and solid electrolyte sensors that react to odorous gas in defecation gas other than methyl mercaptan gas such as hydrogen sulfide, acetic acid, trimethylamine, and ammonia. Analyze. As a result, an analysis result reflecting the results of poor physical condition and bad lifestyle habits is obtained, and this analysis result should be used as an index based on objective data for improving physical condition and lifestyle habits that increase cancer risk. Can do.

The defecation gas contains not only odorous gases but also H ₂ and methane. When semiconductor gas sensors or solid electrolyte sensors are used as gas sensors, these sensors also react with H ₂ and methane. End up. Furthermore, when a measuring device using a semiconductor gas sensor or a solid electrolyte sensor is set in each household, these sensors may react with a fragrance or perfume.
On the other hand, as will be described in detail later, the inventors use a hydrogen sensor, a methane sensor and a column to separate the influence of hydrogen and methane from the detection data of the semiconductor gas sensor and the solid electrolyte sensor, and We established a method for removing the effects of fragrances and perfumes as noise by detecting defecation behavior. In this way, the effects of hydrogen and methane are separated from the data detected by semiconductor gas sensors and solid electrolyte sensors, and furthermore, the effects of fragrances and perfumes are removed, and only the amount of odorous gas in the defecation gas is estimated. Became possible.

Further, the amount of methyl mercaptan and other odorous gases contained in the defecation gas is very small compared to H ₂ and methane. For this reason, even if a semiconductor gas sensor or a solid electrolyte sensor is used, the mixed gas amount of these odorous gases may not be measured accurately.
On the other hand, the inventors have a healthy intestinal environment that is acidic, but when they become cancer patients, an odorous gas containing a sulfur component is generated and the amount of the gas increases. In addition, the intestinal environment becomes alkaline, and the amount of bifidobacteria and the like is reduced, so that the amount of healthy gas such as CO ₂ , H ₂ , and fatty acid is inversely proportional to the increase in the amount of odorous gas We paid attention to the fact that it will definitely decrease continuously.
For this reason, the inventors do not necessarily have high measurement accuracy in each measurement, but the correlation between the amount of odorous gas such as methyl mercaptan and the amount of healthy gas components such as CO ₂ and H ₂ is calculated daily. We thought that the occurrence of advanced cancer could be detected by monitoring during defecation.

  Therefore, the inventors measure the amount of healthy gas and odorous gas contained in the defecation gas of healthy people in their 60s or younger, healthy people in their 60s to 70s, patients with early cancer, and patients with advanced cancer. As a result, a result as shown in FIG. 43 was obtained. That is, the defecation gas of a healthy person has a large amount of healthy gas and a small amount of odorous gas. On the other hand, the defecation gas of cancer patients has a small amount of healthy gas and a large amount of odorous gas. And the amount of the health system gas contained in the defeased gas of advanced cancer is decreasing compared with early cancer. Furthermore, when the amount of healthy gas and the amount of odorous gas are intermediate amounts between a cancer patient and a healthy person, it is considered to be a gray zone, that is, a non-disease state. For this reason, the inventors measure the gas amount of the health system gas and the gas amount of the odorous gas of the subject based on the above-mentioned knowledge, and think that the determination accuracy of the health state can be improved based on these correlations. It was.

Further, FIGS. 44 to 50 show measurement data comparing various gas amounts contained in the defecation gas between a healthy person and a colorectal cancer patient (including advanced cancer and early cancer).
44 is a graph comparing the amount of hydrogen sulfide contained in the defecation gas between healthy subjects and colorectal cancer patients, FIG. 45 is methyl mercaptan gas, FIG. 46 is hydrogen gas, FIG. 47 is carbon dioxide gas, FIG. 48 is a graph comparing propionic acid gas, FIG. 49 is acetic acid gas, and FIG. 50 is a graph comparing the amount of butyric acid gas between a healthy person and a colorectal cancer patient. In these figures, the measurement data for healthy subjects are plotted with circles, the measurement data for colorectal cancer patients are plotted with triangles, and the average value of each is shown with a short line segment.

  As is apparent from the measurement data in FIGS. 44 to 50, the amount of various gases contained in the defecation gas varies widely between healthy subjects and colorectal cancer patients, but odorous gases such as hydrogen sulfide gas and methyl mercaptan gas. With regard to, there are many data showing a large amount of gas in patients with colorectal cancer, and there is almost no data showing a large amount of gas in healthy individuals. On the other hand, with respect to hydrogen gas and carbon dioxide gas, many data showing a large amount of gas are found in healthy subjects, and almost no data showing a large amount of gas is seen in patients with colorectal cancer. In this way, the amount of odorous gas, which indicates the risk of colorectal cancer, contained in the defecation gas is large in colorectal cancer patients and small in healthy individuals, while hydrogen gas and carbon dioxide, which are healthy gases, are present. The amount of carbon gas is high in healthy people and low in colorectal cancer patients. Furthermore, while propionic acid gas, acetic acid gas, and butyric acid gas, which are short chain fatty acid gases, are detected in healthy individuals, in colon cancer patients, these gases are hardly contained in defecation gas. I understand that. This data shows that the amount of these short-chain fatty acid gases, odorous gases, and health-related gases varies greatly from one measurement to another, but if short-chain fatty acid gases are detected, the subject is almost Definitely showing good health. Furthermore, the relationship between odorous gas and healthy gas is reversed in healthy subjects and colorectal cancer patients, and by measuring these gases continuously several times over a predetermined period, the physical condition of the subject is reliably measured. It shows what you can do.

  In addition, the inventors measured the defecation gas, and when performing a plurality of excretion actions (an act of discharging one fart or one stool) at the time of one defecation, the first excretion It was found that the amount of defecation gas discharged with the action was large and odorous gas was also included. Therefore, in the present embodiment, in order to accurately measure a trace amount of odorous gas, the health condition of the subject is analyzed based on the first stool gas. As a result, when measuring the amount of gas from the second and subsequent excretion actions, the effects of feces and farts excreted by the first excretion action may be affected.

In addition to the increase in odorous gases such as methyl mercaptan gas, patients suffering from colorectal cancer, etc., and subjects whose physical condition is getting worse often show some symptoms of defecation such as constipation or diarrhea This has been clarified by an investigation by the present inventors. Therefore, in the biological information measurement system 1 of this embodiment, in addition to the gas physical condition analysis based on the detection data by the gas sensor, the measurement accuracy of the physical condition is detected by detecting the stool state by the defecation / urine detection sensor which is a stool state detection sensor Is increasing.
The biological information measurement system 1 of the present embodiment is based on the measurement principle described above. The odorous gas in the following description includes methyl mercaptan gas, which is an odorous gas containing a sulfur component, and odorous gases such as hydrogen sulfide other than methyl mercaptan, methyl mercaptan, acetic acid, trimethylamine, and ammonia. It is a waste.

Next, a specific configuration of the biological information measurement system 1 of the present embodiment will be described in detail.
As shown in FIG. 1A, the subject-side device 10 in the biological information measurement system 1 is attached to the flush toilet 2 in the toilet room R, and a part thereof is incorporated in the toilet seat 4 with a buttocks washing function. In the toilet seat 4 with a butt washing function, as a measuring device 6, there are a suction device 18 that sucks the gas in the bowl 2a of the flush toilet 2 and a gas detection device 20 that detects a specific component contained in the sucked gas. It has been incorporated. The suction device 18 also serves as a part of the function of a deodorizing device incorporated in the toilet seat 4 with a normal butt washing function. The gas sucked by the suction device 18 is deodorized by the deodorizing device, and then the bowl 2a. Returned in. Further, each device incorporated in the toilet seat 4 such as the suction device 18 and the gas detection device 20 is controlled by a control device 22 (FIG. 2) built in the toilet seat side.

As shown in FIG. 2, the subject-side device 10 includes a measurement device 6 incorporated in the toilet seat 4 and a data analysis device 60 built in the remote controller 8.

As will be described later, the hydrogen gas sensor and the odorous gas sensor can be an integrated sensor.

  The temperature sensor 32 measures the temperature of a detection unit such as the odorous gas sensor 26. The humidity sensor 30 measures the humidity of the gas sucked from the bowl 2a. The sensor sensitivity of these sensors slightly changes depending on the temperature of the detection unit. In addition, a change in humidity due to urination or the like similarly affects the sensitivity of the sensor. In the present embodiment, since the amount of odorous gas is very small, the toilet side is used in accordance with the temperature and humidity measured by these sensors 30 and 32 so that the minute amount of gas can be measured accurately and stably. The CPU 22a controls a sensor heating heater 54 and a humidity adjusting device 59 (FIG. 3), which will be described later, so as to accurately maintain the sensor temperature and suction humidity of the sensors 30 and 32 within a predetermined range, thereby determining the predetermined temperature and humidity environment. Adjust to. Note that these sensors and devices are not essential, and are desirably provided to improve accuracy.

The entrance detection sensor 34 is, for example, an infrared sensor, and detects entry / exit of the subject into the toilet room R.
The seating detection sensor 36 is, for example, an infrared sensor or a pressure sensor, and detects whether or not the subject is seated on the toilet seat 4.
In the present embodiment, the defecation / urine detection sensor 38 is a microwave sensor. As shown in FIG. 1B, the defecation / urine detection sensor 38 is attached to the back surface of the toilet seat 4, irradiates microwaves toward the water surface of the bowl 2a, and detects the height of the water surface based on the reflected waves. It is configured as follows. Since the relationship between the height of the reservoir surface and the volume of the reservoir water in the bowl 2a is obtained in advance, the volume of feces and urine excreted in the bowl 2a is measured by measuring the rising width of the reservoir surface. be able to.

  In addition, the defecation / urine detection sensor 38 can measure the rise of the reservoir surface when stool or urine is excreted as a time-series waveform. Therefore, based on the rising pattern of the water surface, such as the rising speed of the water surface and the vibration of the water surface due to undulations, whether the material excreted in the bowl 2a is urine, feces, or stool It can be estimated whether the water is floating or sinking, whether the stool is diarrhea, or the like. In the present embodiment, the fecal state analyzing means 60a built in the data analyzing device 60 estimates the type of excreted stool and the amount of stool based on the waveform measured by the defecation / urine detection sensor 38. . The flight state analyzing means 60a includes a microprocessor (not shown) provided in the data analyzing device 60 and software for operating the microprocessor. Alternatively, the defecation / urine detection sensor 38 can be constituted by a CCD, a pressure sensor for measuring the pressure at the bottom of the stored water, a water level sensor for measuring the level of the stored water, or the like.

The toilet lid opening / closing device 40 is a device for opening / closing the toilet lid according to the situation based on a detection signal from the entrance detection sensor 34 or the like.
The nozzle drive device 42 is a device that is used for butt washing, and is a device that cleans the butt of the subject after defecation. The nozzle driving device 42 is configured to drive the nozzle to wash the flush toilet 2.
The nozzle cleaning device 44 is a device for cleaning the nozzles of the nozzle driving device 42. In this embodiment, hypochlorous acid is generated from tap water, and the nozzle is cleaned with the generated hypochlorous acid. It is configured.

The toilet flushing device 46 is a device for discharging water or tap water stored in a flush water tank (not shown) into the toilet bowl and washing the bowl 2a of the flush toilet 2. The toilet bowl cleaning device 46 is normally operated by the operation of the remote controller 8 by the subject and cleans the inside of the bowl 2a. However, as will be described later, the toilet cleaning device 46 is automatically operated by the control device 22 according to the situation.
The toilet sterilizer 48 generates, for example, sterilized water such as hypochlorous acid water from tap water, sprays the generated sterilized water onto the bowl 2a of the flush toilet 2, and sterilizes the bowl 2a. It is.

The fragrance sprayer 50 is a device for spraying a predetermined fragrance into the toilet room R. This is provided in order to prevent the subject from spraying an arbitrary fragrance into the toilet room R and spraying an odor component that would cause a measurement disturbance. By providing the fragrance sprayer 50, a fragrance that does not affect a predetermined measurement can be sprayed in a predetermined amount at a predetermined time according to the situation, and the biological information that the fragrance has been sprayed. The measurement system 1 can recognize it. Thereby, disturbance to the physical condition measurement is reduced and the analysis result is stabilized, so that the fragrance sprayer 50 functions as an output result stabilization unit.
The suction device 18 includes a fan for sucking the gas in the bowl 2a of the flush toilet 2, and the sucked gas flows through the detection unit such as the odorous gas sensor 26 and is then deodorized by the deodorizing filter. . The detailed configuration of the suction device 18 will be described later.

The deodorized air supply device 52 is a device that discharges air that has been sucked and deodorized by the suction device 18 into the bowl 2a.
The sensor warming heater 54 is for heating and activating a detection unit such as the odorous gas sensor 26. Each sensor can accurately detect a predetermined gas component by maintaining the detection unit at a predetermined temperature.
The duct cleaner 58 is a device for cleaning the inside of the duct 18a attached to the suction device 18 with, for example, hypochlorous acid obtained by electrolyzing tap water.

  In the present embodiment shown in FIG. 1, the suction device 18, the deodorizing air supply unit 52, and the duct cleaner 58 are integrally configured as a deodorizing device. That is, the gas in the bowl 2a is sucked into the duct 18a by the suction device 18, the sucked gas is deodorized by the deodorizing filter 78 (FIG. 3), and the deodorized gas is released into the bowl 2a again. Thereby, the gas reacting with the odor gas sensor 26 flows into the bowl 2a from the outside, and the gas component in the bowl 2a is prevented from changing due to factors other than the defecation gas discharged from the subject during the defecation period of the subject. Is done. Therefore, the deodorizing device and the deodorizing air supply device 52 provided with the deodorizing filter 78 function as output result stabilizing means. Alternatively, as a modified example, a measurement gas supply device (not shown) that allows gas that does not react with each gas sensor to flow into the bowl 2a is provided, and the measurement gas equivalent to the gas sucked by the suction device 18 is provided. The present invention can also be configured to flow into the bowl 2a. In this case, the measurement gas supply device (not shown) functions as an output result stabilization unit that stabilizes the analysis result.

  Next, as shown in FIG. 2, the remote control 8 has a built-in data analysis device 60. The data analysis device 60 includes a subject identification device 62, an input device 64, a transceiver 66, and a display device. 68 and a speaker 70 are connected. In the present embodiment, the transceiver 66, the display device 68, and the speaker 70 function as an output device that outputs an analysis result by the data analysis device 60. The data analysis device 60 includes a CPU, a storage device 60c, a program for operating these, and the like, and a database is constructed in the storage device 60c.

In this embodiment, the input device 64 and the display device 68 are configured by a touch panel, and receive various inputs such as subject identification information such as the subject's name, and display various information such as physical condition measurement results. It has come to be.
The speaker 70 is configured to output various alarms, messages, etc. issued by the biological information measurement system 1.
In the subject specifying device 62, subject identification information such as the subject's name is registered in advance. When the subject uses the biological information measuring system 1, the registered subject is displayed on the touch panel, and the subject selects his / her name.

  Further, the transmitter / receiver 66 on the remote control 8 side is communicably connected to the server 12 via a network. For example, the subject terminal 14 includes a device capable of displaying received data, such as a smartphone, a tablet PC, or a PC.

The server 12 includes a defecation gas database. In the defecation gas database, measurement data including the amount of odorous gas and the amount of health gas in each defecation behavior in association with the subject identification information of each subject using the biological information measurement system 1, and reliability data And are recorded along with the measurement date. The server 12 stores a diagnostic table and has a data analysis circuit.
Furthermore, the server 12 is connected to a medical institution terminal 16 installed in a hospital, a health institution, or the like via a network. The medical institution terminal 16 is composed of a PC, for example, and can browse data recorded in the database of the server 12.

Next, the configuration of the gas detection device 20 built in the toilet seat 4 will be described with reference to FIG.
First, in the biological information measurement system 1 of the present embodiment, a semiconductor gas sensor is used as a gas sensor in the gas detection device 20 in order to detect odorous gas and hydrogen gas.
Further, in order to detect carbon dioxide, the gas detection device 20 uses a solid electrolyte type sensor.
The semiconductor gas sensor has a detection unit made of a metal oxide film containing tin oxide or the like. In a state where the detection unit is heated to several hundred degrees, when the heated detection unit is exposed to a reducing gas, an oxidation / reduction reaction occurs between oxygen adsorbed on the surface and the reducing gas. The semiconductor gas sensor can detect the reducing gas by electrically detecting a change in the resistance value of the detection unit due to the oxidation / reduction reaction. The reducing gas that can be detected by the semiconductor gas sensor includes hydrogen gas and odorous gas. In this embodiment, the semiconductor gas sensor is used for both the sensor for detecting odorous gas and the sensor for detecting hydrogen gas. However, the detection unit used in the odorous gas sensor reacts strongly to the odorous gas. As described above, the materials of the detection units are adjusted so that the detection units used in the hydrogen gas sensor react strongly with hydrogen gas.

  As described above, in the present embodiment, the “semiconductor gas sensor” is used as the “odor gas sensor”. As described above, this “semiconductor gas sensor” is other than the methyl mercaptan gas to be detected. The general thing which reacts also widely with odorous gas is used. In addition, a solid electrolyte sensor can be used as an “odor gas sensor” as will be described later, but the solid electrolyte sensor also reacts widely with other odorous gases in addition to methyl mercaptan gas as with the semiconductor gas sensor. You can use a common one. In other words, a gas sensor that reacts only with methyl mercaptan gas is extremely difficult to manufacture, and even if manufactured, it becomes an extremely large and expensive gas sensor. If such a large and expensive gas sensor is adopted, a biological information measurement system is manufactured at a cost that can be sold as a consumer product, even if it can be realized as a medical device used in advanced clinical examinations. It becomes impossible. In the biological information measurement system of the present embodiment, a simple, general-purpose gas sensor that reacts to other odorous gases other than the methyl mercaptan gas to be detected is adopted as the “odorous gas sensor”. This makes it possible to realize a living body information measurement system as a consumer product. As described above, the gas sensor employed in the present embodiment is a sensor that also reacts with methyl mercaptan gas and odorous gas other than methyl mercaptan gas. It will be referred to as “odorous gas sensor”. Representative examples of the odorous gas to which the “odorous gas sensor” employed in the present embodiment reacts include methyl mercaptan gas, hydrogen sulfide gas, ammonia gas, and alcohol-based gas.

  In addition, the “odorous gas sensor” employed in the biological information measuring system 1 of the present embodiment is a sensor that reacts to other odorous gases in addition to the target methyl mercaptan gas, but will be described later. Due to various measures, even if such a gas sensor is used, it is possible to measure with sufficient accuracy as a consumer product. Specifically, in a toilet room where various odorous gases exist, data on defecation gas is extracted from the device for improving the measurement environment and detection signals from the gas sensor, assuming the defecation behavior of the subject. Ingenuity in data processing, even when detection data with a large error is obtained, ingenuity to prevent an excessive psychological burden on the subject can be mentioned. Details of each device point will be described later.

  In this embodiment, a case where a semiconductor gas sensor is used as a sensor for detecting odorous gas and hydrogen gas will be described. However, a solid electrolyte sensor can be used instead. The solid electrolyte sensor is a sensor that detects a gas based on an ion permeation amount that passes through the solid electrolyte by heating a solid electrolyte such as stable zirconia, for example. Gases that can be detected by the solid electrolyte sensor include hydrogen gas and odorous gas. In this embodiment, a solid electrolyte sensor is used as a sensor for detecting carbon dioxide. The carbon dioxide sensor is not limited to these, and an infrared method or the like may be used. A sensor for detecting carbon dioxide can be omitted.

As shown in FIG. 3, in the present embodiment, a gas detection device 20 is disposed inside the suction device 18.
The suction device 18 includes a duct 18a directed downward, an intake passage 18b oriented substantially in the horizontal direction, and a suction fan 18c disposed on the downstream side of the intake passage 18b. A duct cleaner 58 and a humidity adjusting device 59 are provided inside the duct 18a.
The gas detection device 20 includes a filter 72 disposed in the intake passage 18b, an odorous gas sensor 26, a hydrogen gas sensor 24, and a carbon dioxide sensor 28.
As shown in FIG. 3, a filter 72 is disposed so as to cross the intake passage 18 b, and an odorous gas sensor 26, a hydrogen gas sensor 24, and a carbon dioxide sensor 28 are juxtaposed on the downstream side of the filter 72.

Further, a deodorizing filter 78 is provided on the downstream side of the odorous gas sensor 26, and the suction device 18 also functions as a deodorizing device by deodorizing the gas taken in by the deodorizing filter 78.
Further, a humidity adjusting device 59 is provided on the downstream side of the deodorizing filter 78. A moisture absorbent is enclosed in the humidity adjusting device 59, and when it is necessary to lower the humidity in the bowl 2a, the air that has passed through the deodorizing filter 78 passes through the enclosed moisture absorbent. Thus, the flow path is switched to remove moisture from the air circulating in the bowl 2a. Thereby, the humidity in the bowl 2a is maintained at an appropriate value, and the detection sensitivity of each gas sensor is maintained substantially constant. Accordingly, the humidity adjusting device 59 functions as an output result stabilizing unit that suppresses a humidity change in the bowl 2a.

  The suction fan 18c sucks off the odorous gas including the odorous gas in the bowl 2a of the flush toilet 2 at a constant speed, deodorizes it, and returns it to the bowl 2a. The deodorizing duct 18a opens in the bowl 2a with the suction port directed downward so that droplets such as urine do not enter the interior. Odorous gases such as methyl mercaptan and hydrogen gas have a low molecular weight, so they rise immediately after defecation. In contrast, in the present embodiment, the exhausted odorous gas and hydrogen gas are reliably introduced into the gas detection device 20 by being sucked by the suction fan 18c from the inlet of the duct 18a opened in the bowl 2a. be able to. Thus, the suction device 18 is operated before the subject starts defecation, and makes the gas sensor contact a gas having a constant flow rate during the defecation period of the subject. Thereby, a stable measurement value can be obtained. Accordingly, the suction device 18 and the control device 22 that operates the suction device 18 function as output result stabilization means.

  The filter 72 is a filter that does not have a deodorizing function, and is configured to pass odorous gas, hydrogen, and carbon dioxide, and prevent passage of foreign matters such as urine and cleaning agents. As such a filter 72, a member that mechanically collects foreign matters, for example, a fine net-like member, without using a chemical reaction, can be used. Thereby, it is possible to prevent the odorous gas sensor 26, the hydrogen gas sensor 24, and the carbon dioxide sensor 28 from being contaminated by urine stones or the like.

  Further, for each gas sensor, a sensor heating heater 54 is provided upstream of each gas sensor and downstream of the filter 72. As described above, the odorous gas sensor 26 and the hydrogen gas sensor 24, which are semiconductor gas sensors, can detect hydrogen and odorous gas in a state where the detection unit is heated to a predetermined temperature. The sensor heating heater 54 is provided to heat the detection units of the odorous gas sensor 26 and the hydrogen gas sensor 24. Also, the carbon dioxide sensor 28 needs to heat the solid electrolyte to a predetermined temperature, and a sensor heating heater 54 is provided. These sensor heating heaters 54 also function as an odor removing device for heating and removing odorous gas components adhering to the sensor. Even when a solid electrolyte sensor is used as an odorous gas sensor or a hydrogen gas sensor, it is necessary to provide a sensor heater for heating the detection unit.

  Further, the sensor heating heater 54 also functions as a means for removing deposits attached to each sensor. Although the gas that has passed through the filter 72 has foreign substances removed, the sucked gas contains various odorous gas components. Such off-flavor gas components adhere to each gas sensor and can cause noise when measuring a minute amount of odorous gas. On the other hand, by heating the detection part of the sensor with the sensor heating heater 54, the off-flavor gas adhering to the sensor can be removed by heating without providing a new device. Moreover, the control apparatus 22 controls the sensor heating heater 54 so that the temperature of each gas sensor becomes constant before the subject's defecation behavior is started. That is, the control device 22 controls the sensor heating heater 54 so as to suppress the temperature of each gas sensor from being lowered due to the contact of the airflow. Thereby, during the test subject's defecation period, the sensitivity of each gas sensor is managed by predetermined value, and the measurement error by each gas sensor can be suppressed. Therefore, the control device 22 and the sensor heating heater 54 function as output result stabilization means for stabilizing the output analysis result.

  Further, the deodorizing filter 78 is a catalytic filter that adsorbs an odorous gas such as an odorous gas. The air from which gas such as odorous gas is removed by the deodorizing filter 78 is returned to the bowl 2a. At this time, if the gas refluxed into the bowl 2a contains odorous gas or the like, the odorous gas or the like flowing into the bowl 2a is again sucked from the duct 18a, and the odorous gas sensor 26 detects again. There is a risk that. For this reason, in this embodiment, the deodorizing filter 78 is arrange | positioned in the downstream of the odorous gas sensor 26, and odor components, such as odorous gas, are reliably removed from the gas returned in the bowl 2a.

  When the subject sits on the toilet seat 4, the upper part of the bowl 2a is closed by underwear or the like. When the inside of the bowl 2a becomes negative pressure, the off-flavor gas component adhering to the body of the subject or clothes is sucked into the bowl 2a. In the biological information measurement system 1 of the present embodiment, the odorous gas sensor 26 is set to have extremely high sensitivity in order to detect odorous gas that is contained in a small amount in the defecation gas. Even the off-flavor gas component adhering to etc. becomes a disturbance to the measurement. On the other hand, in this embodiment, since the gas after deodorization is returned into the bowl 2a, the inside of the bowl 2a does not become negative pressure, and the off-flavor gas component adhering to the body of the subject, clothes, etc. Can be prevented from being drawn into the bowl 2a.

  Here, the semiconductor gas sensor used as the odorous gas sensor 26 detects not only odorous gas but also hydrogen. For this reason, it is necessary to separate the influence of hydrogen gas from the detection data detected by the semiconductor gas sensor. In this embodiment, as a hydrogen separation mechanism for separating the influence of such hydrogen gas, the hydrogen gas sensor 24 detects the odorous gas detected by the semiconductor gas sensor in the gas detection device 20. By subtracting the detection value of the hydrogen gas, the influence of the hydrogen gas is separated and output as the detection value of the odorous gas sensor 26. A configuration including such a hydrogen separation mechanism, a semiconductor gas sensor, and a hydrogen gas sensor 24 and outputting a detection value corresponding to the amount of odorous gas and the amount of hydrogen gas is referred to as a detection value output mechanism. The arithmetic processing for subtracting the detected value of the hydrogen gas detected by the hydrogen gas sensor 24 from the detected value of the odorous gas detected by the semiconductor gas sensor may be performed in the data analysis device 60 or the like. In this embodiment, a hydrogen separation mechanism for separating the influence of hydrogen gas from detection data detected by the semiconductor gas sensor will be described. By providing a methane sensor for detecting methane, detection data detected by the semiconductor gas sensor is provided. It is also possible to separate the effects of methane from As the methane gas sensor, a semiconductor gas sensor adjusted so that the material of the detection unit strongly reacts with methane may be used.

  In many people's intestines, there are no methanogens that produce methane, or even if they exist, the amount of methane is very small. Few. For this reason, in this embodiment, the hydrogen sensor 24 and the carbon dioxide sensor 26 are provided as health system gas sensors. However, rarely, there are people who have very many methanogens in their intestines. As described above, the defecation gas of a person having a very large number of methanogenic bacteria in the intestine has a large amount of methane produced but a small amount of hydrogen produced. For this reason, when only the hydrogen sensor 24 and the carbon dioxide sensor 26 are provided, the fecal gas of a person who has a very large amount of methanogenic bacteria in the intestine is judged to be less preferable because the amount of discharged health gas is small. In this embodiment, the hydrogen sensor 24 and the carbon dioxide sensor 26 are provided as health gas sensors in order to suit many people, but a methane gas sensor is provided instead of the hydrogen sensor 24 according to people with a large amount of methane gas. May be. Furthermore, by providing a methane gas sensor in addition to the hydrogen sensor 24 and the carbon dioxide sensor 26 in advance, any subject can be handled, which is more preferable.

As described above, the defecation gas contains a large amount of hydrogen, but the semiconductor gas sensor detects not only odorous gas but also hydrogen. On the other hand, since the influence of hydrogen can be separated by subtracting the amount of hydrogen gas detected by the hydrogen gas sensor 24 from the amount of gas detected by the odorous gas sensor 26 which is a semiconductor gas sensor, it is possible to accurately The amount of odorous gas can be measured.
Further, the hydrogen gas contained in the defecation gas has a very small molecular weight as compared with air, and easily escapes from the bowl 2a. On the other hand, in this embodiment, since the defecation gas is sucked by the fan 18c of the suction device 18, the defecation gas containing hydrogen gas can be reliably collected.

  Moreover, if the sucked defecation gas is returned to the bowl 2a as it is, the measurement accuracy by the odorous gas sensor 26 decreases. On the other hand, in this embodiment, since the sucked defecation gas is deodorized by the deodorizing filter 78 and returned to the bowl, the amount of odorous gas and the amount of hydrogen can be accurately measured. Further, such a deodorizing filter 78 needs to be disposed on the downstream side of each sensor. However, if such a deodorizing filter 78 is provided on the downstream side of each sensor, the sensor may be directly contaminated with foreign substances. . On the other hand, in this embodiment, since the filter 72 that does not have the deodorizing function is provided on the upstream side of the sensor, the contamination of the sensor with foreign substances can be reduced without affecting the odor component measurement.

  Further, when the gas in the bowl 2a is sucked, the pressure in the bowl 2a is lowered, and there is a possibility that the off-flavor gas component adhering to the body and clothes of the subject flows into the bowl 2a. On the other hand, in this embodiment, since the air from which the odor components after deodorization are removed is returned to the bowl 2a, the flow of off-flavor gas components adhering to the body and clothes of the subject into the bowl 2a is prevented. Accurate measurement became possible.

  However, it is not essential to return the air from which the odor components after deodorization are removed to the bowl 2a. Thus, when the structure which returns the air which removed the odor component after deodorizing in the bowl 2a is not employ | adopted, there exists a possibility that the off-flavor gas component adhering to a test subject's body and clothes may flow in in the bowl 2a. However, as will be described later with reference to FIG. 9, when setting the residual gas reference value, the residual gas reference is included after including the influence of the off-flavor gas components adhering to the body and clothes of the subject. Value is set. For this reason, it is possible to estimate the gas amount without returning the air from which the odor components after deodorization are removed to the bowl 2a.

Next, with reference to FIG.4 and FIG.5, the flow which measures a physical condition with the biological information measuring system 1 by 1st Embodiment of this invention is demonstrated.
FIG. 4 is a diagram for explaining the flow of physical condition measurement. The upper part shows each process in the physical condition measurement, and the lower part shows an example of a screen displayed on the display device of the remote controller in each process. FIG. 5 is a diagram illustrating an example of a screen displayed on the display device of the remote controller.

  In the biological information measuring system 1 of the present embodiment, the physical condition including the determination of cancer is analyzed based on the correlation between the odorous gas in the defecation gas released by the subject at the time of defecation and the health gas. Here, it is preferable that each subject-side apparatus displays the analysis result during the defecation period or in a short period of time after the end of a single defecation period until it exits. However, if the analysis is performed in a short time, the analysis accuracy may be lowered. In addition, it is difficult to suck all of the defecation gas discharged by the subject with the suction device 18, and these are disturbances in a measurement environment where the toilet bowl or toilet is very unsanitary or the fragrance is strong. May affect the measurement accuracy. Therefore, in each subject-side device, when the physical condition including the presence / absence of illness is transmitted to the subject, the time-lapse results of measurement during many defecation behaviors over a long period of time are taken into account. Based on this, instead of strongly transmitting only the absolute amount of odorous gas highly relevant to cancer, the change in the physical condition of the subject, that is, the change in the intestinal state is transmitted strongly. Also, taking into account measurement errors at the time of each bowel movement, in the present embodiment, the subject is notified based on the measurement result at the time of one bowel movement so that the physical condition notified to the subject does not change significantly. It is devised to be notified. This utilizes the characteristic that the disease of cancer is a disease that progresses over a long period of time. The amount of odorous gas that is strongly related to cancer in a short period of time is greatly related to cancer. This is because it is not strong, but is often caused by bad lifestyle habits or the influence of noise, and if the physical condition changes greatly, it causes unnecessary psychological anxiety to the subject.

  In view of the above points, in the present embodiment, first, in the subject-side device 10, based on the measurement result of the first defecation gas in one defecation behavior, that is, based on the defecation gas discharged during the first excretion action. , Simply analyze the health condition, and display the analysis result of the health condition. On the other hand, the server 12 can perform more detailed analysis by comparing with other subjects based on the total amount of gas discharged during a single defecation action. Therefore, in the biological information measurement system 1 of the present embodiment, simple analysis is performed in the subject-side device 10 installed in the toilet room R, and more detailed analysis is performed in the server 12.

  As shown in FIG. 4, in the measurement at the time of one defecation action by the biological information measurement system 1 of the present embodiment, the pre-measurement environment preparation step S1, the measurement start preparation step S2, and the measurement reference value setting step S3 The measurement process S4, the examination process S5, the communication process S6, and the post-measurement environment maintenance process S7 are executed.

The pre-measurement environment maintenance step S1 is a step performed before the subject enters the toilet room R. Whether or not the subject has entered the toilet room R is detected by the entrance detection sensor 34 (FIG. 2).
In the pre-measurement environment maintenance step S1, the control device 22 on the toilet seat side changes and controls the sensor warming heater 54, the suction device 18, and the toilet lid opening / closing device 40 to the measurement standby mode. In the measurement standby mode, the sensor heating heater 54 is based on the temperature measured by the temperature sensor 32 so that the temperature of the detection unit of the odorous gas sensor 26 is lower than the temperature at the time of measurement (for example, 200 ° C.). It is controlled to become. In the measurement standby mode, the suction device 18 is controlled so that the suction air volume is minimized. The toilet lid opening / closing device 40 is controlled so that the toilet lid is closed in the measurement standby mode.

  In the pre-measurement environment maintenance step S1, the detection unit of the odorous gas sensor 26 measures the gas concentration of the odorous gas although the sensor warming heater 54 is in the measurement standby mode and is lower than the optimum temperature. Is possible. When there is a source of off-flavor gas in the bowl 2a, such as when there is attached stool in the flush toilet 2, the gas concentration measured by the odorous gas sensor 26 becomes a predetermined value or more. When the gas concentration value measured by the odorous gas sensor 26 exceeds a predetermined value in the pre-measurement environment maintenance step S1, the control device 22 performs toilet cleaning. Specifically, the control device 22 discharges the cleaning water from the nozzle by the nozzle driving device 42 to clean the bowl 2a, and discharges the water stored in the cleaning water tank by the toilet cleaning device 46 into the bowl 2a. The bowl 2a is washed, or the sterilizer 48 generates sterilized water such as hypochlorous acid water from tap water, and sprays the generated sterilized water onto the bowl 2a to sterilize the bowl 2a. Do.

  Further, when the gas concentration measured by the odorous gas sensor 26 is equal to or higher than a predetermined value, the control device 22 can operate the suction device 18 to discharge the gas in the bowl 2a, thereby reducing the gas concentration. Since the gas sucked by the suction device 18 is deodorized by the deodorization filter 78, the suction device 18 and the deodorization filter 78 function as a deodorization device. Further, by sucking the gas with the suction device 18 with the toilet lid open, not only the inside of the bowl 2a but also the toilet room R can be deodorized. It can also function as a deodorizing device. Preferably, when the suction device 18 and the deodorization filter 78 are functioned as a deodorization device, the amount of gas sucked by the suction device 18 is set larger than when the physical condition is measured during the defecation period of the subject.

  Alternatively, a ventilation device (not shown) provided in the toilet room R may be configured to be controlled by the control device 22, and the gas concentration may be lowered by operating the ventilation device. In this way, the concentration of the odorous gas remaining in the bowl 2a is reduced, and the influence of residual gas noise caused by the remaining gas is reduced. Therefore, the cleaning or sterilization of the bowl 2a by the nozzle drive device 42, the toilet bowl cleaning device 46 or the toilet bowl sterilization device 48, and the exhaust / deodorization in the bowl 2a or the toilet room R performed in the pre-measurement environment maintenance step S1 are as follows. It functions as noise countermeasure means for reducing the influence of residual gas noise and residual gas removal means for reducing the concentration of residual odorous gas. Further, the noise countermeasure means executed when the subject is not in the toilet room R and is outside the subject's defecation period functions as the first noise countermeasure means and also as the residual gas removing means.

  Furthermore, if the amount of gas measured by the odorous gas sensor 26 does not become less than a predetermined value even after the toilet bowl cleaning described above is performed in the pre-measurement environment maintenance step S <b> 1, the control device 22 causes the transceiver 56 to perform a cleaning warning. Send command signal. When the transmitter / receiver 66 on the remote control 8 side receives the cleaning warning command signal, the display device 68 or the speaker 70 notifies the subject to wash the toilet.

  In addition, in the pre-measurement environment maintenance step S1, the control device 22 periodically performs suction environment cleaning. Specifically, the control device 22 drives the duct cleaner 58 and sprays cleaning water into the duct 18a of the suction device 18 to clean the duct 18a and the like. Further, the hydrogen heater 24, the odorous gas sensor 26 and the carbon dioxide sensor 28 are heated to a high temperature by the sensor heating heater 54, and the off-flavor gas components adhering to the surfaces of these gas sensors 24, 26 and 28 are burned out.

  Next, when the entrance of the subject is detected by the entrance detection sensor 34, the control device 22 transmits a signal to start the measurement start preparation step S <b> 2 to the transmitter / receiver 66 on the remote control 8 side via the transmitter / receiver 56. The measurement start preparation step S2 is performed in synchronization with the remote control side.

  In the measurement start preparation step S2, first, the subject specifying device 62 incorporated in the remote controller 8 specifies a subject. Specifically, the resident of the house where the system is installed is registered in the biological information measurement system 1, and the registered resident is displayed as a candidate for the subject. That is, as shown in FIG. 5, "subject A", "subject B", "subject C",. . The candidate's button is displayed, and when the subject entering the toilet room R presses the button corresponding to himself / herself, the subject is identified. Further, the data analysis device 60 built in the remote controller 8 refers to the storage device 60c, and the physical condition display table as the past measurement data of the personal identification information received by the subject identification device 62 and the reference data serving as a reference for analysis. To get.

  Further, in the measurement start preparation step S2, as shown in FIG. 5, the data analysis device 60 performs the previous defecation such as “Did you defecate in another place?” On the second stage of the display device. Questions regarding whether or not this was done in the toilet where the device was installed, and the answer options “Yes (this morning)”, “Yes (yesterday afternoon)”, “Yes (yesterday morning)”, “before yesterday” “No” is displayed. When the subject answers this question, the defecation history information of the subject is input to the input device 64 of the data analysis device 60. Defecation history information relating to the elapsed time from the previous defecation behavior of the subject is stored in the storage device 60c (subject information storage device) built in the remote controller 8, and is registered in advance in the subject information storage device. Subject information related to the subject's weight, age, sex, and the like is also stored. The subject and measurement date and time specified by the subject specifying device 62 are transmitted to the server 12 as defecation history information for each subject together with the result of gas physical condition analysis and the result of fecal state physical condition analysis, which will be described later, and recorded in the database of the server 12. The

  In the measurement start preparation step S2, the toilet-side control device 22 controls the sensor heating heater 54, the suction device 18, the defecation / urine detection sensor 38, and the toilet lid opening / closing device 40 to the measurement mode. In the measurement mode, the sensor heating heater 54 is controlled based on the temperature measured by the temperature sensor 32 so that the temperature of the detection unit of the odorous gas sensor 26 becomes a temperature suitable for measurement (350 ° C.). Further, in the measurement mode, the suction device 18 is controlled to be constant so that the suction air volume is increased to an air volume that prevents the defecation gas from leaking outside from the bowl 2a and does not fluctuate from such air volume. Further, the toilet lid opening / closing device 40 is controlled to open the toilet lid in the measurement mode.

  Further, the control device 22 operates a water supply pump (not shown) to allow the cleaning water to flow into the bowl 2a and adjust the water level of the stored water surface to the predetermined measurement start water level L. In a normal flush toilet, the water level in the bowl is set near the highest point 2b (FIG. 1B) of the drain trap. On the other hand, in the biological information measurement system 1 of the present embodiment, since the amount of excrement of the subject is measured based on the rise in the stored water level, if the stored water level is in the vicinity of the highest point 2b, When there is excretion, the accumulated water in the bowl 2a overflows through the drain trap, and the amount of excrement cannot be measured accurately. For this reason, in the biological information measurement system 1 of this embodiment, the water level before the start of measurement is set to a predetermined measurement start water level L sufficiently lower than the highest point 2b, and the water overflows due to the excretion of the subject. I am trying not to. That is, in the present embodiment, in the toilet flushing after using the flush toilet 2, the water level after completion of refilling is set to be lower than the measurement start water level L. Then, when the subject enters the toilet room next time, the water level is adjusted to the measurement start water level L by operating a water supply pump (not shown) in the measurement start preparation step S2 to flow in the wash water. The At this time, the control device 22 causes the defecation / urine detection sensor 38 to irradiate microwaves to the water surface of the bowl 2a and operates a water supply pump (not shown) based on the measured water level. After the accumulated water level is set to the predetermined measurement start water level L, the defecation / urination detection sensor 38 starts measuring the accumulated water level.

In the measurement start preparation step S <b> 2, when the odorous gas concentration detected by the odorous gas sensor 26 is high, the control device 22 performs sterilization in the bowl 2 a by the toilet sterilization device 48.
Further, in the measurement start preparation step S2, when the humidity measured by the humidity sensor 30 is a value that is not suitable for the measurement of the defecation gas by the odorous gas sensor 26, the control device 22 sends a signal to the humidity adjustment device 59. To control the humidity in the bowl to an appropriate value.

  In the measurement start preparation step, when the toilet seat 4 is cleaned with a sheet using an alcohol-based disinfectant or spraying, the odorous gas sensor 26 reacts with alcohol and the gas concentration value increases rapidly. Thus, when the gas concentration measured by the odorous gas sensor 26 increases rapidly, the data analysis device 60 displays a warning on the display device 68.

In addition, the data analysis device 60 stores the measurement value obtained by the odorous gas sensor 26 as an environmental reference value that is a noise level serving as a base for defecation gas measurement. Based on this environmental reference value, the data analysis device 60 determines whether or not measurement is possible. If the data analysis device 60 determines that the noise level is being measured or cannot be measured, the display device 68 causes the display device 68 to read “Preparing for measurement! ”Is displayed to prompt the subject to wait for defecation.
Thus, in the measurement start preparation step S2, noise caused by odorous gas remaining before the subject entered the toilet room, or subject noise caused by odorous components adhering to the entered subject. Is determined before the subject is seated, and is stored as an environment / subject-derived noise reference value, and whether or not measurement is possible is determined.

Next, when the seating detection sensor 36 detects that the subject is seated, the control device 22 transmits a signal indicating that the measurement reference value setting step S3 is started to the data analysis device 60 via the transceiver 56. The measurement reference value setting step S3 is performed in synchronization with the data analysis device 60. In addition, when the seating detection sensor 36 repeats detection and non-detection a predetermined number of times, it is an effect of cleaning of the toilet seat by the subject, and in such a case, it is desirable to return to S1.
In the measurement reference value setting step S <b> 3, the data analysis device 60 performs subject adhering odor noise determination, which is determination of a noise level caused by the subject, based on the measurement value measured by the odorous gas sensor 26. That is, when the measured value measured by the odorous gas sensor 26 is sufficiently lowered and not stable, it is determined that there is a possibility that sterilization with an alcohol-based disinfectant or the like has been performed, and FIG. Continue to display “Preparing for measurement! Please wait if you can” as shown below. Alternatively, when the noise level caused by the subject is equal to or higher than a predetermined value, the data analysis device 60 sends a signal to the nozzle driving device 42 which is a local cleaning device to activate it, and performs the subject's tail washing. Alternatively, the data analysis device 60 notifies the subject by the display device 68 so that the subject performs the butt washing. As described above, the execution of the buttocks cleaning by the data analysis device 60, the notification for prompting the notification, and the notification that the noise to the subject is large, the second noise correspondence that reduces the subject noise by a measure different from the first noise handling means. Functions as a means. Further, the first noise countermeasure means described above is executed when the subject does not enter the toilet room R, whereas the second noise countermeasure means is executed when the subject enters the toilet room R. The On the other hand, when the measured value measured by the odorous gas sensor 26 is sufficiently lowered, this display is deleted. If the measured value measured by the odorous gas sensor 26 does not decrease sufficiently even after a predetermined time has elapsed, the data analysis device 60 stops measuring the physical condition and displays the fact on the display device 68 to indicate the subject. To inform. As described above, the data analysis device 60 stops the physical condition measurement of the subject when it is determined that the gas component in the bowl 2a before the defecation period of the subject is not suitable for measurement. Function.

In the measurement reference value setting step S3, the data analysis device 60 sets a reference value for gas amount estimation based on the gas concentration measured by the odorous gas sensor 26, as will be described in detail later.
Next, as will be described in detail later, the data analysis device 60 changes the stored water level measured by the defecation / urine detection sensor 38 when the measured value by the odorous gas sensor 26 rises greatly from the reference value. When it is determined that the subject has excreted. The data analysis device 60 performs the measurement step S4 until it is detected by the seating detection sensor 36 that the subject has left the seat after it is determined that the subject has excreted.

In the measurement step S4, the control device 22 includes a hydrogen gas sensor 24, an odorous gas sensor 26, a carbon dioxide sensor 28, a humidity sensor 30, a temperature sensor 32, an entrance detection sensor 34, a seating detection sensor 36, and defecation / urination. Detection data measured by the detection sensor 38 is transmitted to the data analysis device 60 via the transceiver 56. The transmitted detection data is stored in the storage device 60c for each subject specified by the subject specifying device 62. Therefore, the storage device 60c functions as a fecal state storage device. The control device 22 transmits these measurement values stored in the storage device 60c to the server 12 via the transceiver 66 after the measurement step S4 ends. In the present embodiment, the measurement value is transmitted from the data analysis device 60 to the server 12 after the measurement step S4 ends. However, the measurement value is not limited to this, and may be transmitted in real time in parallel with the measurement.
Further, the control device 22 starts the measurement of the defecation gas even when the subject does not input the information for identifying the subject to the subject identifying device 62. The detection data detected before the information is input is stored in the storage device in association with the input subject information when the subject inputs the subject information during one stool. This is a practical device tailored to the characteristics of defecation so that various inputs can be made after calming down in a tight situation such as defecation. Further, if the subject does not input subject information even after a predetermined time has elapsed after the start of measurement, a message prompting the subject to input is output from the display device 68 and the speaker 70 to notify the subject. Thereby, a test subject's forgetting input can be prevented.

  At the same time, as in the measurement reference value setting step S3, the data analysis device 60 determines whether or not measurement is possible. If it is determined by the data analysis device 60 that measurement is possible, the data analysis device 60 uses the display device 68 as shown in the lower row of FIG. An indication that the measurement is being performed is presented to the subject.

Next, when it is detected by the seating detection sensor 36 that the subject has left the seat, the control device 22 transmits a signal indicating that the examination process S5 is started to the data analysis device 60 via the transceiver 56. When receiving this signal, the data analysis device 60 starts the medical examination step S5.
First, the data analysis device 60 calculates the measurement reliability, which will be described in detail later, based on the measurement values measured by the sensors.
On the other hand, the control device 22 prohibits the flush toilet 2 from being washed when information for identifying the subject is not input even after the subject has left the seat. That is, when the subject specifying information is not input, even if the subject operates a cleaning button (not shown) of the remote controller 8, the control device 22 does not discharge the cleaning water of the flush toilet 2 and prompts input. Is displayed. Thereby, it is possible to strongly urge the subject to input subject identification information.

Further, as will be described in detail later, the data analysis device 60 estimates the gas amounts of odorous gas and hydrogen gas (health gas).
Further, in the screening process S5, the data analysis device 60 analyzes the physical condition of the subject based on the temporal changes of the plurality of detection data detected in a plurality of stool performed within a predetermined period and stored in the storage device. A medical examination result is calculated and a time-lapse diagnosis based on the stored value is performed. Then, the advice content based on the diagnosis over time is selected. As shown in the third row of FIG. 5, the data analysis device 60 displays the selected advice content on the display device 68 as a message related to health management. In the example shown in FIG. 5, the current physical condition of the subject falls under “physical illness” as a result of the screening, and advice is “The intestinal environment seems to be bad. Try to live a healthy life.” It is displayed.

  Further, below the examination result, the amount of health gas such as hydrogen gas and carbon dioxide gas in this measurement and the amount of poor physical condition gas such as odorous gas are displayed. Under the advice, measurement results for the past four times are also displayed. Further, when the subject presses the “detail screen” button on the display screen, a table showing the physical condition change of the subject for the past month is displayed. When the “stool status” button on the display screen is pressed, the stool status of the subject over time measured by the defecation / urination detection sensor 38 is displayed. These displays will be described later. As described above, the analysis results displayed on the display device 68 of the remote controller 8 include only the physical condition, advice, and physical condition change (measurement data history). Notifications regarding disease determination results are not included. These analysis results may be notified to the subject terminal 14.

  Further, as shown at the bottom of FIG. 5, the reliability of the current measurement data is displayed at the bottom of the display device 68. In the example shown in FIG. 5, the reliability is displayed as “4”, which is relatively high. When the reliability is low, the reason why the reliability has decreased and advice for improving the reliability are displayed under the reliability display. For example, if the residual gas noise caused by the gas remaining in the bowl or the subject noise caused by the subject is large, the reliability is lowered and the subject is notified that the noise affects the measurement result. . Therefore, the display of reliability by the display device 68 functions as noise countermeasure means. The calculation of reliability will be described later.

Next, when the control unit 22 detects that the subject has left the room by the entrance detection sensor 34, the control unit 22 transmits a signal indicating that data transmission is performed to the data analysis device 60 via the transceiver 56. When receiving this signal, the data analysis device 60 performs a communication step S6.
In the communication step S6, the data analysis device 60 obtains the information for identifying the subject specified by the subject specifying device 62, the data measured by various sensors, the calculated reliability, the measurement date / time information, and the defecation / urination detection sensor 38. The notification data including the flight status information regarding at least one of the flight volume and the flight status and the bowel movement history information are transmitted to the server 12 via the network. The server 12 records the received information in a database.

In addition, after the subject leaves the room by the entrance detection sensor 34, the control device 22 performs a post-measurement environment maintenance step S7.
The control device 22 measures the gas concentration by the odorous gas sensor 26 in the post-measurement environment maintenance step S7. When the gas concentration measured by the odorous gas sensor 26 is larger than a predetermined value even after a predetermined time has elapsed after the end of the defecation period, the control device 22 has stool adhesion on the bowl 2a of the flush toilet 2 And the wash water stored in the wash water tank by the toilet flushing device 46 is discharged into the bowl 2a to wash the inside of the bowl 2a, or the hypochlorine from tap water by the toilet flushing device 48 Disinfecting water such as acid water is generated, and the generated disinfecting water is sprayed on the bowl 2a to sterilize the bowl 2a.

  The additional toilet flushing by the toilet flushing device 46 and the sterilization of the bowl 2a by the toilet flushing device 48 function as a residual gas removing means for reducing the concentration of the remaining odorous gas. Preferably, the toilet cleaning performed automatically by the residual gas removing means is set to have a higher cleaning power than the normal toilet cleaning performed by the subject operating a cleaning switch (not shown) of the remote controller 8. Keep it. Specifically, in the toilet bowl cleaning performed by the residual gas removing means, it is preferable to set a large number of times of discharge of the cleaning water to the bowl 2a or to set a high flow rate of the cleaning water. Further, the sterilization of the bowl 2a performed by the residual gas removing means is performed by setting the sterilization power stronger than the normal bowl sterilization performed by the subject operating the sterilization switch (not shown) of the remote controller 8. deep. Specifically, in the bowl sterilization performed by the residual gas removing means, the sterilization water having a higher concentration than that of the normal sterilization is sprayed or a large amount of the sterilization water is sprayed.

Furthermore, if the gas concentration measured by the odorous gas sensor 26 is greater than a predetermined value even after a predetermined time has elapsed after the end of the defecation period, the residual gas removing means determines that the duct 18a is dirty. The duct cleaner 58 is activated. The duct cleaner 58 cleans the inside of the duct 18a attached to the suction device 18 with hypochlorous acid or the like obtained by electrolyzing tap water.
In addition, the residual gas removing means is a flush toilet when the gas concentration measured by the odorous gas sensor 26 is not sufficiently lowered even when the above washing and sterilization processes are executed and is larger than a predetermined value. 2 is displayed on the display device 68.

  In the post-measurement environment maintenance step S7, the control device 22 changes the sensor heating heater 54, the suction device 18, the defecation / urine detection sensor 38, and the toilet lid opening / closing device 40 to the measurement standby mode, End measurement.

Next, the physical condition display table will be described with reference to FIG. This physical condition display table is a table displayed by pressing the “detail screen” button on the display screen shown in FIG. 5.
In the storage device on the remote control 8 side, the physical condition display table, the date and time of defecation of each subject in association with the subject identification information, and past measurement data are recorded for each subject. The past measurement data stored in the storage device on the remote control 8 side may be data for the entire period during the defecation period, but due to the relationship with the capacity of the storage device, it is discharged by the first excretion action during the defecation period. The measurement data of the defecation gas (measurement data of the first excretion action period) is preferable.

  As shown in FIG. 6, the physical condition display table is a table determined based on the experiment conducted by the inventors described above, and the result of the gas physical condition analysis based on the detection data regarding the odorous gas is displayed on the physical condition display table. Is done. The physical condition display table includes an index relating to the amount of odorous gas (which is a poorly conditioned gas on the display) on the vertical axis, and a gas of healthy gas which is the second index on the horizontal axis. It is a graph showing the parameter | index regarding quantity. The first index is related to the amount of odorous gas based on the first detection data detected by the gas detection device 20, and the second index is the second detection data detected by the gas detection device 20. Based on the amount of hydrogen gas, which is a health gas. On the display device 68 of the remote controller 8, the measurement results of the defecation gas of the subject are displayed as plot points over time on such a physical condition display table having a vertical axis and a horizontal axis. That is, as shown in FIG. 6, the plot point representing the latest measurement result of the same subject is “1”, the previous result is “2”, and the previous result is “3”. . . As a result, the past 30 plot points are displayed together with numbers. Thereby, the test subject can recognize the temporal change of his / her physical condition. In this embodiment, the number is 30 times, but it may be several weeks or months, and may be a year by considering that the progression of cancer is a year. It is more desirable for the subject to be able to change the display range according to the situation. Furthermore, when the display range is large, the display method is easy to see, such as one year or two years on a monthly average. It goes without saying that it is even better to change in consideration of the above.

  Further, in the physical condition display table, “disease suspicion level 2”, “disease suspicion level 1”, “physical illness level 2”, “physical dysfunction level” are set according to the relationship between the index related to health gas and the index related to odorous gas. A plurality of regions are set according to whether the physical condition is good, such as “1” and “good physical condition”. Here, as shown in FIG. 6, “disease suspicion level 2” corresponding to the state of the worst physical condition is that the amount of odorous gas is the largest and the amount of healthy gas is the smallest in the physical condition display table. It is set in the upper left area. On the other hand, “good physical condition” corresponding to the best physical condition is set in the lower right region of the physical condition display table where the amount of odorous gas is the smallest and the amount of healthy gas is the largest. The areas of “disease suspicion level 1”, “physical condition level 2”, and “physical condition level 1” indicating physical condition levels between these are set in order from the upper left as a band-like area that rises to the right on the physical condition display table. Has been. Such a physical condition display table is set in advance according to the weight, age, sex, etc. of the subject. By displaying plot points based on the first and second indices on this table, the detection data and the subject are displayed. Gas condition analysis based on information can be performed.

As described above, in the present embodiment, since the two indexes of the index regarding the gas amount of the odorous gas and the index regarding the gas amount of the health-related gas are used, the change in the physical condition and the physical condition of the subject can be described in more detail. Can be evaluated. For example, even if the amount of healthy gas that indicates good physical condition is large, if the amount of odorous gas is also large, the evaluation is not the most satisfactory level (in the physical condition display table). Upper right area). On the other hand, even if the amount of healthy gas that indicates good physical condition is very small, if the amount of odorous gas is small, the evaluation is not the most bad level (physical condition display table). Lower left area).
In addition, for example, the boundary line between “physical condition level 1” and “physical condition level 2” indicating a state of poorer physical condition indicates that the index for the amount of healthy gas on the horizontal axis increases and the odor characteristic on the vertical axis. The “physical condition level 2” representing a state of poor physical condition is distributed on the larger side of the index related to the odorous gas amount of the boundary line. Since the boundary line is set in this way, in this embodiment, even if the index related to the amount of healthy gas on the horizontal axis is the same value, the condition of the physical condition depends on the value of the index related to the amount of odorous gas on the vertical axis. The evaluation will be different. In order to obtain an equivalent evaluation, the value of the health gas amount on the horizontal axis needs to increase as the value of the odorous gas amount on the vertical axis increases.

  Further, advice corresponding to the physical condition is recorded in the storage device on the remote controller 8 side. Specifically, the advice “please go to the hospital” for the physical condition “suspected disease level 2”, the advice “recommend to the hospital” for the physical condition “suspected disease level 1”, the physical condition “physical condition” “Unsatisfactory level 2” suggests that “disease concerns will increase. Stress reduction and lifestyle improvement will be urgently improved”, but “physic condition level 1” indicates “intestinal environment seems to be bad. The advice “Let's keep life” is recorded in association with the advice “physical condition is good” in association with the physical condition “good physical condition”. On the physical condition display table, advice corresponding to the area where the latest plot point is located is displayed together with the plot points indicating the physical condition of the subject.

  However, the plotted points shown on the physical condition display table of the display device 68 of the remote controller 8 do not indicate the analysis results analyzed by the data analysis device 60 as they are, and are corrected according to predetermined predetermined conditions. The plot point is shown at the moved position. Here, the disease assumed to be detected by the biological information measurement system 1 of the present embodiment is colon cancer or the like, and such a disease does not progress rapidly within a few days. On the other hand, the living body information measuring system 1 according to the present embodiment sucks the defecation gas from the bowl 2a of the flush toilet 2 installed in the toilet room R, and analyzes the sucked gas. I can't do it. In addition, when the subject is wearing perfume, or when the gas reacting with the odorous gas sensor 26 such as odorous gas remains in the toilet room R, an error occurs in the physical condition measurement result due to various factors. There is a fear.

For this reason, if the displayed physical condition swings to the side with a bad physical condition based on one measurement result of a test subject, an unnecessary psychological burden is given to the test subject. In addition, if the physical condition measurement result fluctuates greatly for each measurement, the test subject's confidence in the physical condition measurement result is lost. For this reason, in the biological information measuring system 1 of the present embodiment, the analysis result correction means 60b (FIG. 2) built in the data analysis device 60 corrects the physical condition analysis result according to a predetermined condition. ing. The analysis result correction means 60b is constituted by a microprocessor (not shown) provided in the data analysis device 60 and software for operating the microprocessor. The analysis result correcting means 60b prevents the displayed analysis result from greatly shaking for each measurement, and improves the reliability of the displayed physical condition of the subject. Here, while the corrected analysis result is stored in the storage device of the remote controller 8, the analysis result transmitted to and stored in the server 12 is the uncorrected analysis result before correction together with the reliability of the detected data. Remembered. It should be noted that the present invention can also be configured such that detection data that has not been corrected is also stored in the storage device of the remote controller 8, and detection data that has been corrected is also transmitted and stored in the server 12. Thus, the detection data obtained by the biological information measurement system 1 of the present embodiment are not all highly reliable. However, it is possible to detect changes in the physical condition of the subject over a long period of time by acquiring data on daily defecation behavior continuously for a long period and accumulating the data in the storage device of the remote control 8 or the server 12. Thus, before the subject's physical condition is greatly deteriorated, attention can be drawn so as not to cause a large disease such as colorectal cancer.
As described above, the correction applied to the detection data functions as an output result stabilization unit that suppresses the physical condition index of the subject output to the display device 68 from being shaken in the direction of poor physical condition due to a detection error or the like.

Next, correction of plot points will be described with reference to FIG.
FIG. 7A is a diagram illustrating an example of movement by correction of the plot points of the latest data, and FIG. 7B is a diagram illustrating limit processing for the movement amount of the plot points.
First, in the example shown in FIG. 7A, the plot point calculated by the data analysis device 60 based on the latest measurement is “1”, and this point is a value determined based on the past analysis result. It is greatly deviated from “history representative value G”. The analysis result correction means 60b built in the data analysis device 60 performs “past history correction” so that the position of the latest plot point “1” approaches the “history representative value G”. In the present embodiment, the centroid G of the plot points of the past 30 detection data is adopted as the “history representative value G”, and the coordinates (X _G , Y _G ) of the centroid G are the past detection data. When the coordinates are (X _i , Y _i ), it can be obtained by Equation (1).
As will be described later, when the second predetermined condition described later is met, such as the reliability of the current detection data is extremely low, the current detection data is excluded from the calculation of the history representative value. (The detection data of this time is not used) and the plot point display based on the detection data of this time is stopped.

Thus, when the plot point “1” that is significantly deviated from the distribution of the detection data up to the previous time is displayed, an excessive psychological burden is given to the subject. Since cancer risk does not increase in a day, such a large change in measurement data may be the result of bad lifestyles the previous day or the effects of noise rather than an increased risk of cancer. high. Therefore, in this embodiment, the correction is performed in consideration of not giving an excessive psychological burden to the subject. Therefore, as described above, the analysis result correction unit 60b determines that the plot point to be displayed is “history representative value” as “past history correction” when the latest analysis result deviates significantly from the “history representative value”. It is corrected in the direction approaching. That is, the position where the plot point “1” is displayed on the physical condition display table is moved by a predetermined distance in the direction of the center of gravity G which is the “history representative value” based on the reliability of the current measurement data. In the example shown in FIG. 7A, the latest measurement data is displayed at the position of the plot point “1 ′” corrected so that the plot point “1” is moved in the direction of the center of gravity G (good physical condition side). (The plot point “1” is not actually displayed). The correction amount (movement distance) of the plot point “1” in the direction of the center of gravity G by the past history correction is changed according to the reliability of the latest detection data, and is increased as the reliability is lower. In this way, the psychological burden on the subject can be reduced by moving the latest plot point to the side showing good physical condition. The calculation of the reliability of the detection data will be described later. In the present embodiment, corrected detection data values are used as detection data (X _i , Y _i ) for calculating the coordinates (X _G , Y _G ) of the center of gravity G.

As a modification, the historical representative value can be calculated by weighting past detection data. For example, the weighted centroid of the past N detection data can be used as the history representative value, and the coordinates (X _GW , Y _GW ) can be determined by Equation (2).
Here, w _i is a “weight”, and the weight w _i multiplied by the latest past detection data is set larger than the weight w _i multiplied by the far past detection data. For example, it is conceivable to set the weight to be multiplied by the detection data for the last one week larger than the weight to be multiplied by the previous detection data. By setting the weight in this way, it is possible to determine a history representative value in which the most recent past detection data is more important than the far past detection data.
As will be described later, when the predetermined second predetermined condition is met, for example, the reliability of the current detection data is extremely low, the weight of the current detection data is made extremely small or 0. (The detection data of this time is not used) and the plot point display based on the detection data of this time is stopped.

  As described above, in the present embodiment, the past history correction is performed so that the plot points based on the latest detection data are not greatly deviated from the history representative value. However, when the latest analysis result is corrected in a direction that shows a good physical condition by the past history correction for a predetermined number of times or more, the analysis result correction unit 60b corrects the correction amount (the latest plot point by the past history correction). Is reduced to the history representative value). As a result, the subject can recognize at an early stage that his / her physical condition is in a tendency to deteriorate, and can prompt his / her to try to improve his / her physical condition.

In addition, when the latest physical condition measurement has a very large noise, and the latest plotted point is greatly deviated, even if the correction described in FIG. It can be considered that the body moves greatly toward the poor physical condition. For this reason, as shown in FIG. 7B, a predetermined limiter is applied to the moving distance of the latest data from the center of gravity G. That is, the movement of the latest data from the center of gravity G is limited to ± 40%, and even when the latest data is deviated by 40% or more from the coordinates of the center of gravity G, the latest data is plotted at a position deviated by 40%. . For example, when the coordinate value of the center of gravity G is (X _G , Y _G ), the range of coordinate values in which the latest data can be plotted is (0.6X _{G to} 1.4X _G , 0.6Y _{G to} 1.4Y _G). ), So that it is not plotted at a position shifted further. That is, the analysis result correction unit 60b (FIG. 2) corrects the analysis result of the physical condition to be output this time so that the distance from the history representative value is equal to or less than a predetermined value.

Furthermore, when the movement of the latest data exceeding 40% continues twice, the range in which the latest data can be moved is reduced to 60%. Thereby, for example, when the coordinate value of the center of gravity G is (X _G , Y _G ), the range of coordinate values in which the latest data can be plotted is (0.4X _{G to} 1.6X _G , 0.4Y _G to 1.6Y _G ). This is because, when large movements of the latest data occur frequently, it is considered that some change in the physical condition of the subject is reflected rather than a simple measurement error.

Next, the fecal state physical condition analysis will be described with reference to FIG. FIG. 8 is a display screen of the result of the fecal state physical condition analysis displayed by pressing the “stool state” button on the display screen shown in FIG. 5.
The storage device 60c of the data analysis device 60 stores “one total defecation amount” that is the total defecation amount in one defecation period of the subject, and “one excretion that is the defecation amount in one excretion action of the subject”. "Volume", "daily stool frequency" which is the number of defecation behaviors per day of the subject, "constipation status" which is the frequency at which the subject becomes constipated, and "soft stool status" which is the frequency at which the subject becomes soft stool As shown in FIG. 8, it is displayed on the display device 68 of the remote controller 8 as a result of the fecal state physical condition analysis. That is, the stool state analysis means 60a performs a stool state physical condition analysis based on the stool state detected by the defecation / urination detection sensor 38 which is a stool state detection sensor, and the data analysis device 60 includes the result of the gas state analysis. The result of the stool state physical condition analysis is output to the display device 68.

  “A total defecation amount” is the total amount of stool excreted by the subject during one defecation period (the period from when the subject sits on the toilet seat 4 until he leaves). Is the amount of stool estimated based on the time series data of the water level measured by. The total amount of defecation during one defecation period is about 150 grams for healthy general men, and is about 250 grams at most, according to the study of the present inventors. On the other hand, for example, since defecation becomes difficult in patients with colorectal cancer, fatigue due to defecation increases, and it becomes difficult to excrete many stools in one defecation period. For this reason, the present inventor's research has revealed that “total amount of defecation at one time” decreases in patients with colorectal cancer and the like and tends to go to the toilet for defecation many times a day. .

  As shown in FIG. 8, the total defecation amount of this time is “1” on the right side of the display of “total defecation amount of one” on the display screen, and the previous defecation period (the subject uses the biological information measurement system 1). The total defecation amount (when the physical condition was measured last time) is plotted as “2”. In the example shown in FIG. 8, the “total amount of defecation at one time” is equal to or greater than the total amount of defecation of a healthy general male, indicating that it is “very good”. On the other hand, when it is less than the standard total defecation amount, it is displayed that “good”, “caution”, and “concern” are at the stage. It should be noted that the reference value for determining whether or not the “total amount of defecation” is good is set according to the age and sex of the subject registered in the storage device of the data analysis device 60.

  Furthermore, as shown in FIG. 8, on the right side of the current and previous total defecation amount display, the transition of the “total defecation amount of one time” in the past 12 months is displayed as a time-series graph. In this graph, the average value of “one total defecation amount” for each month is displayed over the past 12 months, and the subject can easily recognize a rough transition of the past total defecation amount. . In the example shown in FIG. 8, it is shown that “one total defecation amount” has changed in the range of “very good” or “good” over the past 12 months. Thus, in addition to the result of the gas physical condition analysis, the result of the fecal state physical condition analysis is also displayed on the display device 68 so that the change with time can be recognized.

  Further, as shown in FIG. 8, “one excretion amount” is displayed below “one total defecation amount”. “One-time excretion” is the amount of stool obtained by averaging the amount of stool in each of the subject's multiple excretions performed during one stool period, and at the water level measured by the stool / urine detection sensor 38. It is calculated based on each excretion amount estimated based on the series data. According to the study by the present inventors, patients who have difficulty in defecation due to colorectal cancer, etc. cannot excrete a large amount of stool in a single excretion, and a small amount that is shredded during one defecation period There is a tendency to excrete the stool many times. For example, a healthy general male discharges about 50 grams of stool with a single excretion, whereas a large amount of excretion tends to decrease in a colon cancer patient or the like who has difficulty in excretion.

  As shown in FIG. 8, the average value of each excretion amount in the current defecation period is “1” on the right side of the display of “one excretion amount” on the display screen, and the average value in the previous defecation period is “2”. 'Is plotted. In the example shown in FIG. 8, “one-time excretion amount” in the current defecation period is “good” to the same extent as that of a healthy general male, and “one-time excretion amount” in the previous defecation period. Was shown to be “very good” at or above the amount of excretion of healthy general men. On the other hand, when the amount is less than the standard one-time excretion, it is displayed that “attention” and “concern” are in the stage. It should be noted that the reference value for determining whether or not “one excretion amount” is good is set to an appropriate value according to the age and sex of the subject registered in the storage device of the data analysis device 60.

  Furthermore, as shown in FIG. 8, the transition of “one excretion amount” in the past 12 months is displayed as a time-series graph on the right side of the current and previous excretion amount display. In this graph, the average value of “one excretion” for each month is displayed over the past 12 months, and the subject can easily recognize the rough transition of the past excretion. it can. In the example shown in FIG. 8, it is shown that “the amount of excretion once” has changed in the range of “very good” and “caution” in the past 12 months.

  In addition, as shown in FIG. 8, “daily defecation frequency” is displayed below “one excretion”. The “daily defecation frequency” relates to the frequency of defecation behavior performed by the subject. It is calculated on the basis of the preparation step S2 "). In other words, while healthy adults perform defecation behavior at approximately the same time period once a day, as described above, in patients with colorectal cancer and the like who have difficulty in defecation, during a single defecation period Only a small amount of stool can be excreted, and there is a tendency to perform defecation behavior many times a day. Moreover, even when the subject has diarrhea, defecation behavior is performed many times a day. Conversely, when the subject has constipation, the defecation frequency (defecation interval) is longer than 24 hours.

  As shown in FIG. 8, the frequency of the current defecation behavior is plotted as “1” and the frequency of the previous defecation behavior as “2” on the right side of the display of “daily defecation frequency” on the display screen. In the example shown in FIG. 8, since the last defecation behavior was almost 24 hours after the previous defecation behavior, the defecation behavior rhythm (defecation frequency) was regular and “very good” The defecation behavior of this time is 24 hours or more after the previous defecation behavior, and is judged to be “good” by being slightly constipated, and is displayed. On the other hand, if there is a bowel movement more than once a day, or if the bowel movement is less than once a day, it is displayed that it is in the “attention” or “concern” stage. The

  Furthermore, as shown in FIG. 8, on the right side of the current and previous defecation frequency displays, the transition of “daily defecation frequency” in the past 12 months is displayed as a time-series graph. In this graph, the average value of “daily stool frequency” for each month is displayed over the past 12 months, and the subject easily recognizes the rough transition of the past “daily stool frequency”. be able to. In the example shown in FIG. 8, it is shown that “daily defecation frequency” has improved from the “concern” stage to the “good” stage in the past 12 months.

  Next, as shown in FIG. 8, “constipation status” is displayed below “daily defecation frequency”. “Constipation status” relates to whether or not the subject has a tendency to constipate, and when the subject uses the biological information measurement system 1, the stool history information input via the remote controller 8 (see “Measurement start preparation” in FIG. Estimated based on the process S2 ") and the like. That is, while a healthy adult performs defecation behavior at approximately the same time period about once a day, when constipation occurs, the interval between defecation behavior is longer than 24 hours.

  As shown in FIG. 8, the current constipation status is plotted as “1” and the previous constipation status as “2” on the right side of the display of “constipation status” on the display screen. In the example shown in FIG. 8, it is displayed that the defecation behavior has been performed about once a day in the previous time, and the “constipation status” is “very good” (not constipated). . In contrast, as the interval between defecation actions becomes longer than once a day, “good”, “caution”, and “concern” are displayed.

  Further, as shown in FIG. 8, the transition of the “constipation status” in the past 12 months is displayed as a time-series graph on the right side of the current and previous constipation status. In this graph, the average value of “constipation status” for each month is displayed over the past 12 months, and the subject can easily recognize a rough transition of the past “constipation status”. In the example shown in FIG. 8, the “constipation status” was in the “concern” stage more than half a year ago, but now it has been improved to the “good” stage.

  Next, as shown in FIG. 8, “soft stool status” is displayed below “constipation status”. The “soft stool situation” relates to whether or not the subject has a tendency to loose stool or diarrhea, and is estimated based on time-series data of the water level measured by the defecation / urine detection sensor 38.

  As shown in FIG. 8, the current soft stool situation is plotted as “1” and the previous soft stool situation as “2” on the right side of the “soft stool situation” display on the display screen. In the example shown in FIG. 8, this time, normal stool is excreted and the “soft stool status” is “very good” (not soft stool). On the other hand, “good” is displayed when there is a possibility that the stool is soft, and “caution” and “concern” are displayed when it is clearly estimated that the stool is soft.

  Furthermore, as shown in FIG. 8, the transition of the “soft stool status” in the past 12 months is displayed as a time-series graph on the right side of the current and previous soft stool status. In this graph, the monthly average value of the “soft stool situation” is displayed over the past 12 months, and the subject can easily recognize the rough transition of the past “soft stool situation”. In the example shown in FIG. 8, the “soft stool situation” has been in the “attention” or “good” stage for the past 12 months, but is currently in the “good” stage.

  As described above, the subject can display the result of the stool state physical condition analysis by pressing the “stool state” button on the display screen shown in FIG. 5. It is possible to recognize the state transition. For this reason, it is possible to clearly recognize the tendency of one's physical condition, such as constipation, or repeated constipation and diarrhea, which can be used for health management. In this embodiment, the result of the stool state physical condition analysis is displayed on the display device 68 provided in the remote controller 8, but the result of the stool state physical condition analysis is a voice or the like by the speaker 70 provided in the remote controller 8. The subject can be notified by any means. Further, the gas condition analysis based on the detection data of the odorous gas can be notified to the subject by any means such as voice.

Next, the server-side diagnosis table will be described with reference to FIG. The following processing in the server is performed by a data analysis circuit provided in the server 12.
FIG. 9 is a diagram illustrating an example of a diagnostic table displayed on the server side. As described above, in the biological information measurement system 1 of the present embodiment, the measurement data for the entire defecation period analyzed by the data analysis device 60 is sequentially transmitted to the server 12 via the Internet and recorded in the database on the server side. Has been. The accumulated measurement data can be displayed on a medical institution terminal 16 installed in a medical institution registered by a subject or the like. For example, when the subject receives a message “Recommend Visit” displayed on the display device 68 of the remote controller 8 and the subject visits a medical institution, the medical institution terminal 16 can display a diagnostic table for the server. It is like that. In the diagnostic table, the vertical axis and the horizontal axis represent the same indices as the physical condition display table displayed on the display device 68 of the remote controller 8, but the physical condition assigned to each region is more specific. It has become. The doctor can refer to the physical condition of the subject over time by referring to the measurement data of the subject recorded in the database on the server 12 side at the medical institution terminal 16, which is useful for examination and treatment in the medical institution. Can do. Alternatively, when the measurement data transmitted to the server 12 indicates a significant physical condition, the subject's terminal 14 for the subject is notified so as to receive a medical examination from a medical institution in which the subject is registered. The present invention can also be configured.

  The diagnosis table displayed on the medical institution terminal 16 is different from the physical condition display table displayed on the display device 68 of the subject as described above. As shown in FIG. 9, the diagnosis table on the server 12 side is a table determined based on the experiment conducted by the inventors described above, and the relationship between the amount of healthy gas and the amount of odorous gas. Corresponding to the disease state is associated. Specifically, in the diagnostic table, depending on the relationship between the amount of healthy gas and the amount of odorous gas, “large colorectal cancer concern”, “early colorectal cancer concern large”, “early colorectal cancer suspect” , “Physical dysfunction level 3”, “Physical dysfunction level 2”, “Physical dysfunction level 1”, “Health condition”, “Intestinal dysfunction (diarrhea)”, and “Suspected mismeasurement” are set. .

  On the server-side diagnosis table set in this way, the past measurement data of the subject is plotted over time, and based on the position of the plotted point, “large colorectal cancer concern”, “early early colorectal cancer concern”, “early” Judgment regarding cancer diseases such as “suspected colorectal cancer” is performed. Note that the plot points displayed in the server-side diagnosis table are not corrected or limited, and the doctor comprehensively determines the displayed data together with the reliability. In addition, since the diagnosis table and the determination result displayed on the medical institution terminal 16 are set on the assumption that the doctor refers to the diagnosis table, the name of the disease and the degree of progression thereof are displayed more specifically. It has become. In addition, when the plot point is located in a region related to cancer diseases such as “large concern about colon cancer”, “great concern about early colorectal cancer”, “suspected early colorectal cancer” over a long period of time, It is displayed that there is a high possibility of The doctor can comprehensively judge the indicated plot points, the reliability of measurement, and the like, and can tell the subject of his / her physical condition. In addition, the medical institution terminal 16 provides the reliability calculated with reference to the database, the data measured by various sensors, the stool volume, the stool status, etc. in addition to the diagnostic table in which the past measurement data is plotted over time The result of the stool state physical condition analysis and the defecation history information can also be displayed.

  In addition, a large number of subject-side devices 10 are connected to the server 12 and measurement data of a large number of subjects are accumulated. Further, the database on the server 12 side stores data on the medical condition of a subject who has visited a medical institution based on certain measurement data as a result of a precise examination at the medical institution. Yes. Therefore, the data measured by the biological information measuring system 1 of the present embodiment and the data relating the actual medical condition can be accumulated on the server 12 side. The diagnosis table on the server side is sequentially updated based on the measurement data of a large number of subjects accumulated in this manner, and more accurate diagnosis can be performed based on the updated diagnosis table. Also, the physical condition display table can be updated based on the data accumulated on the server side. The physical condition display table updated based on the data on the server side is downloaded to each subject apparatus 10 via the Internet and displayed on the display device 68 of the remote controller 8. However, even if the physical condition display table is updated, the physical condition display table that is directly presented to the subject has been corrected to an appropriate content to be shown to the subject.

Next, with reference to FIG. 10, the data detected by each sensor provided in the biological information measurement system 1 of the present embodiment and the estimation of the gas amount based thereon will be described.
FIG. 10 is a graph schematically showing detection signals from the sensors provided in the biological information measurement system 1 in one defecation of the subject. In FIG. 10, the hydrogen gas sensor 24, the carbon dioxide sensor 28, the odorous gas sensor 26, the humidity sensor 30, the defecation / urine detection sensor 38, the temperature sensor 32, the seating detection sensor 36, and the entrance detection sensor 34 are detected in order from the top. The signal waveform is shown.

  The estimation of the gas amount based on the detection signal of each sensor and the measurement and estimation of the stool amount and the stool state are performed by the data analysis device 60 which is a physical condition determination means for determining the physical condition, that is, a CPU incorporated in the remote controller 8. And the storage device or the CPU and storage device of the server 12. The data analysis device 60 reads from the storage means of the remote controller 8 and starts the excretion action start time point, and the gas amount change rate threshold value and the gas amount that enables stable measurement. A stability threshold is set in advance. In addition, fart is included in the excretion act here.

First, at time t ₁ in FIG. 10, the room entry detection sensor 34 detects the entrance of the subject. The data analysis device 60 measures the amount of odorous gas with the odorous gas sensor 26 even in a state (time t _{0 to} t ₁ ) before the subject enters and exits the toilet room R by the entry detection sensor 34. . Even in this state, the odorous gas sensor 26 reacts and outputs a certain level of detection signal due to the influence of the fragrance and the residual stool adhering to the bowl 2a of the flush toilet 2.
Thus, the measured value of the odorous gas sensor 26 before the subject enters the room is set as the environmental reference value of the gas amount that is residual gas noise. In the state before the entrance detection sensor 34 detects the entrance, the odorous gas sensor 26 and the suction device 18 are in a power saving state, and the sensor heating heater 54 for heating the detection portion of the odorous gas sensor 26 is used. The temperature is set low, the rotational speed of the suction fan 18c is suppressed, and the flow rate passing therethrough is also low.

Next, when the entrance detection sensor 34 detects that the subject has entered the room at time t ₁ , the odorous gas sensor 26 and the suction device 18 are activated. As a result, the temperature of the sensor heating heater 54 of the odorous gas sensor 26 rises, and the rotational speed of the fan of the suction device 18 increases, so that a predetermined flow rate of gas is sucked. As a result, the value detected by the temperature sensor 32 rises once and then converges to an appropriate temperature (from time t _{1 in} FIG. 10). In the present specification, a period (time t _{1 to} t _{8 in} FIG. 10) during which the entrance detection sensor 34 detects entry of the subject into the toilet room R is called one “defecation action”. . When the subject enters the room, the detection signal detected by the odorous gas sensor 26 increases. This is because the odorous gas sensor 26 reacts to the body odor of the subject, the perfume used, the hairdressing agent, and the like. That is, the increase from the residual gas noise before the subject enters the toilet room R is subject noise caused by the subject. The noise measurement circuit built in the data analysis device detects residual gas noise caused by the gas remaining in the bowl 2a and subject noise caused by the subject. The odorous gas sensor 26 is set to extremely high sensitivity for the purpose of detecting an extremely small amount of odorous gas contained in the ppb order in the defecation gas discharged into the toilet bowl. It also reacts to odors that cannot be felt.

Next, at time t ₂ in FIG. 10, when the subject is seated on the toilet seat 4 is detected by the seating detection sensor 36, this point is set as the starting point of one bowel movement period of the subject. In the present specification, a period during which the seating detection sensor 36 detects the subject's seating on the toilet seat 4 (time t _{2 to} t _{7 in} FIG. 10) is referred to as one “defecation period”. Then, the detected value by the odorous gas sensor 26 after the start time (time t ₂ ) of the defecation period and immediately before the start of the first excretion action (time t _{5 in} FIG. 10) is used as the reference value of the residual gas. Set as.

In the example shown in FIG. 10, after the subject is seated at time t ₂ , the detection value of the humidity sensor 30 rises between time t _{3 and} t ₄ , and the inside of the bowl 2 a measured by the defecation / urination detection sensor 38. The water level in the water has also risen. This is the detection of urination of the subject, and since the detection value of the odorous gas sensor 26 has hardly changed, the data analysis device 60 determines that no excretion is performed. Next, at time t ₅ , the detection values of the hydrogen gas sensor 24 and the odorous gas sensor 26 rise sharply, while the rise in the water level by the defecation / urine detection sensor 38 is not detected. As described above, when the detected value of the odorous gas sensor 26 suddenly rises during the defecation period after the subject is seated, the data analysis device 60 determines that the excretion action has been performed. Also, increase in the water level of the accumulated water in the bowl 2a is because they are not detected, bodily functions of the subject at time t ₅ is determined to be fart.

  When the excretion action is performed, the data analysis device 60 is based on the waveform shape of the rise of the detection value by the odorous gas sensor 26 from the reference value of the residual gas (the hatched portion of the graph of the detection value by the odorous gas sensor 26). Estimate the amount of odorous gas discharged from the subject. Thus, since the data analysis device 60 estimates the amount of odorous gas based on the rise from the reference value, the influence of noise caused by the subject can be suppressed. Therefore, the circuit built in the data analysis device 60 that performs this calculation functions as a noise suppression circuit and also functions as a second noise countermeasure unit that reduces the influence of subject noise. Further, when the noise level caused by the subject is equal to or higher than a predetermined value, the data analysis device 60 notifies the display device 68 of the fact. Similarly, the data analysis device 60 estimates the amount of hydrogen gas discharged from the subject based on the rise of the detected value by the hydrogen gas sensor 24 from the reference value of the residual gas.

After excretion by the subject (time t _{5 in} FIG. 10), the detection values by the odorous gas sensor 26 and the hydrogen gas sensor 24 return to the reference value of the residual gas. Then, at time t _6, the excretion behavior of the second by the subject is performed, again odorous gas sensor 26, the carbon dioxide sensor 28, the detection value of the hydrogen gas sensor 24 and defecation, urination detecting sensor 38, it rises rapidly. As for the second excretion action, similarly to the first excretion action, the amount of odorous gas and hydrogen gas discharged from the subject is estimated based on the rising waveform from the reference value of the residual gas. Further, in the second excretion action, the detection value of the defecation / urination detection sensor 38 is also increased, so it is determined that this excretion is defecation. In addition, when estimating the amount of odorous gas and hydrogen gas in the second and subsequent excretion actions, the standard value is changed each time in consideration of the effects of floating stools floating in the sealed water in the bowl. May be. In this way, when the subject has performed excretion multiple times after entering the room (that is, when a change in the gas amount equal to or greater than a predetermined threshold is detected multiple times), the stool associated with each excretion The amount of gas is estimated in the same way.

Then, by the seating detection sensor 36 unseated subjects completed defecation period once detected at time t ₇ in FIG. 10, the entrance detecting sensor 34 at time t ₈ the exit of the subject is detected, defecation once The action ends. The data analysis device 60 estimates the amount of stool gas associated with each excretion until the entry detection sensor 34 detects that the subject has left the room. Further, the fecal state analyzing means 60a built in the data analyzing device 60, based on the detection waveform by the defecation / urine detection sensor 38, the amount of defecation in each excretion action (one excretion amount), and one defecation period In addition to estimating the total amount of defecation (total amount of defecation once), the state of excreted stool is estimated.

Based on the amount of the defecation gas measured in this way, the gas condition analysis of the subject is executed in the remote controller 8 and the server 12. Further, based on the detection signal from the defecation / urine detection sensor 38, the fecal state analysis unit 60a performs fecal state physical condition analysis for estimating the stool amount, the fecal state and the like. Here, in the gas physical condition analysis, it is desirable that the remote controller 8 can display the measurement of the physical condition during the defecation period or immediately after the defecation period. And if excretion is performed several times, since the stool accumulates in the bowl 2a, the accuracy of the measurement of the gas amount by the odorous gas is lowered. On the other hand, the defecation gas or fart that was first discharged from the subject within one “defecation period” is the gas that stayed near the rectum of the subject and the gas that stayed in the body for the longest time. Therefore, it can be said that it is a defecation gas that best reflects the intestinal state of the subject. For this reason, when the detection data of the odorous gas sensor 26 first rises from the odorous noise reference value at a rate of change equal to or greater than a positive predetermined value (that is, time t _{5 in} FIG. 10), ”Is estimated to be the beginning of the subject's first excretion action (first excretion), and detection data (for example, detection data within a predetermined time from time t ₅ ) on the initial excretion action after this point The measurement of the state is preferable because of its high reliability.

Further, the fecal gas excreted as a fart tends to have a higher concentration of odorous gas such as methyl mercaptan and higher gas content than the fecal gas excreted together with feces. For this reason, it is desirable to adopt the defecation gas by the fart excreted first in one defecation period as detection data. In the example shown in FIG. 10, the rise of the detection value by the odorous gas sensor 26 and the hydrogen gas sensor 24 at time t ₅ is due to the fart, and the rise of the detection value at time t ₆ is due to defecation. As described above, it is desirable to employ the detection data at time t ₅ for gas condition analysis. Conversely, if defecation gas with defecation is detected first, and then defecation gas by fart is detected, the first defecation gas is not analyzed and the first excretion of defecation gas by the next fart is detected The data is preferably selected for gas physical condition analysis. In this embodiment, the detection data of the defecation / urine detection sensor 38 is used to distinguish the defecation gas accompanied by defecation from the fart, and the detection data of the odorous gas used for the gas physical condition analysis is selected. .

Based on these, on the remote control 8 side, when the amount of defecation gas (the amount of odorous gas and hydrogen gas) from the first excretion can be estimated, the subject is based only on the amount of defecation by the first excretion. Is displayed on the display device 68 of the remote controller 8. Alternatively, the gas physical condition analysis can be executed so that the weighting of the measurement value based on the detection data related to the initial excretion action in one defecation action becomes heavier than the weighting related to the late excretion action.
In this way, the data analysis device 60 performs the gas physical condition analysis based on the detection data at the time of the first excretion during the defecation period, while the fecal state analysis means 60a includes the entire defecation period detected by the defecation / urination detection sensor 38. The stool state physical condition analysis (FIG. 8) is executed based on the stool state over the range.

  On the other hand, on the server 12 side, the gas physical condition analysis may be performed using the total amount of defecation gas resulting from a plurality of excretion actions. For this reason, on the server 12 side, the total amount of defecation gas (total amount of odorous gas and hydrogen gas) due to multiple excretion actions, more preferably all included in one defecation period from sitting to sitting The physical condition of the subject is determined based on the total amount of defecation gas due to the excretion of the subject. Note that the gas condition analysis of the subject on the server 12 side does not necessarily have to be the total amount of defecation gas due to all excretion actions included in one defecation period, but all excretion actions included in many defecation periods It is preferable that it is based on the total amount of defecation gas.

  Further, as described above, the measurement data of the gas amount of the odorous gas and the gas amount of the health gas of the new subject are sequentially accumulated in the database of the server 12. In the database of the server 12, the medical checkup result of cancer that the subject has received at the medical institution from the medical institution terminal 16 is recorded in association with the identification information of the subject. The server 12 updates the recorded diagnostic table based on the change in the history of the change in the gas amount of the odorous gas and the health-related gas, as well as the results of such a medical checkup for cancer.

  FIG. 11 is a diagram illustrating an example of updating the diagnosis table. For example, as a result of plotting and analyzing the measurement data A of the odorous gas and healthy gas of the subject in the old diagnostic table, even if it is determined as "suspected early colorectal cancer", Suppose this patient is diagnosed with early colorectal cancer. In such a case, as shown in FIG. 11, “large colorectal cancer concern” and “early large bowel cancer concern” are included so as to include a portion corresponding to measurement data A of a subject diagnosed with early colorectal cancer. , Expand the area of "suspected early colorectal cancer" and narrow the area of "hypophyseal level". On the contrary, for example, in the old diagnostic table, even if it is determined that “early colorectal cancer is suspected” from the correlation between the gas amounts of odorous gas and healthy gas, the result of the medical examination is suspected of cancer. If there are a large number of subjects diagnosed as having none, expand the “disease level” area, and narrow the “colon cancer concerns”, “early colorectal concerns”, and “early colorectal cancer suspects” areas . When the diagnostic table is updated, the areas of the display table are changed in the same manner.

  In addition, the server 12 stores a plurality of physical condition display tables that are categorized according to the tendency of the history of changes in the measurement data of the odorous gas and the health gas, and the attribute information such as the subject's weight, age, and sex. .

  When the subject-side device 10 wishes to perform a more detailed physical condition analysis, attribute information such as the subject's weight, age, and sex is registered in the server 12 together with the subject's identification information. Then, when the measurement data of the subject who desires this more detailed analysis is accumulated in the server 12, the server 12 selects a physical condition display table with conditions close to the history of changes in the attribute information and measurement data of the subject. . The server 12 transmits the selected physical condition display table to the subject apparatus 10 via the network. When the test subject side apparatus 10 receives a new physical condition display table from the server 12, the subject side apparatus 10 changes the already stored physical condition display table to the received physical condition display table. Thereby, in the subject side apparatus 10, the more accurate physical condition analysis according to a test subject's attribute and the log | history of measurement data can be performed.

  In the above-described embodiment, the subject-side device 10 is configured to store the history of the measurement data. However, the measurement data is not limited to this, and the measurement data is stored only in the database of the server 12, and the subject side The apparatus 10 may read a history of past measurement data from the database of the server 12 and perform a screening result calculation and a continuous diagnosis in the screening process S5.

  Here, the calculation method of the reliability in the screening process S5 of FIG. 4 will be described in detail below. As a characteristic of the semiconductor gas sensor used as the odorous gas sensor 26, not only the odorous gas but also the odorous gas around the fragrance, the sanitizing sheet, etc., and the odorous gas adhering to the body and clothes of the subject are detected. Sometimes. Furthermore, the detected value of the odorous gas detected by the semiconductor gas sensor varies depending on the state of the stool (for example, whether or not it is a diarrhea state) and the amount of stool. For this reason, when determining the disease regarding cancer, it is calculated | required that the magnitude of the influence of these off-flavor gas noise and the state of a stool can be evaluated. In the present embodiment, the reliability determination circuit provided in the data analysis device 60 of the subject apparatus 10 installed in the toilet room is used to measure the influence of such odor gas noise of the defecation gas, the state of the stool, and the like. An event that affects the accuracy is evaluated, and the measurement reliability is determined as an index indicating the accuracy of gas detection by the gas detection device 20.

  FIG. 12 is a diagram for explaining a method of determining the measurement reliability. In the following description, a case where correction is performed by the influence of the off-flavor gas adhering to the subject's body or clothes, the influence of humidity, the influence of temperature, and the influence of the number of defecation gases will be described as an example. The determination of the following measurement reliability is performed using a reliability determination circuit that determines the reliability of detection of odorous gas in the data analysis device 60 of the remote controller 8.

  The outputs from the hydrogen gas sensor 24, odorous gas sensor 26, carbon dioxide sensor 28, humidity sensor 30, temperature sensor 32, entrance detection sensor 34, seating detection sensor 36, and defecation / urine detection sensor 38 of the measuring device 6 are transmitted from the remote control 8. Are sent to the data analysis device 60. FIG. 12 shows an example of outputs from these sensors.

  In addition, a plurality of reliability correction tables for calculating reliability are recorded in the data analysis device 60 of the remote controller 8 in advance.

  FIGS. 13 to 16 respectively show a subject-adherent off-flavor gas noise correction table for determining the influence of off-flavor gas adhering to the body and clothes of the subject, a humidity correction table for determining the influence of humidity, and the influence of temperature. It is a figure which shows the temperature correction table for performing, and the excretion count correction table for determining the influence by the frequency | count of excretion.

  The semiconductor gas sensor used as the odorous gas sensor 26 detects off-flavor noise (environmental noise) other than the defecation gas adhering to the subject. It can be said that the reliability of measurement is low when the amount of off-flavor gas components (noise amount) attached to the subject is large. For this reason, as shown in FIG. 13, in the test subject attached odor gas noise correction table, a correction value is determined for the amount of attached odor gas noise. That is, when the noise in the current measurement is large, the correction amount by the past history correction is made larger than when the noise is small, and the displayed analysis result is brought closer to the history representative value. Specifically, when the amount of the off-flavor gas component adhering to the subject is less than a predetermined value, the correction value is set to 1 as a value that is not corrected, and when the amount of the off-flavor gas component adhering to the subject is a predetermined amount or more. When the amount of noise of the off-flavor gas component adhering to the subject is too much larger than the predetermined amount, the negative correction amount from 1 is increased in order to gradually decrease the reliability value as the amount of off-flavor gas component increases. Is determined to be unmeasurable (correction value 0) because it corresponds to one of predetermined second predetermined conditions. The amount of attached odor gas noise is determined based on the detection data detected by the odorous gas sensor 26 during the non-defecation period before the seating detection sensor 36 detects that the subject has been seated. In addition, since the off-flavor gas component adhering to the subject affects the entire defecation period, not a part during the defecation period, the reliability is corrected over the entire defecation period. Hereinafter, this correction of reliability over the entire defecation period is referred to as “overall correction”.

  Further, when the subject urinates, the humidity in the bowl 2a increases, and the humidity of the gas that reaches the detection unit of the odorous gas sensor 26 increases. When the humidity of the gas that reaches the odorous gas sensor 26 increases, the resistance of the odorous gas sensor 26 changes and the sensor sensitivity decreases. Moreover, when urine is applied to the attached stool in the bowl 2a, the attached stool becomes soft from the dry state, and a large amount of defecation gas is temporarily released from the attached stool while the urine is applied again in the bowl 2a. There is. The defecation gas released from the attached stool may be detected by the odor gas sensor as noise when measuring the defecation gas released from the subject. For this reason, as shown in FIG. 14, in the humidity correction table, 1 is set when the humidity measured by the humidity sensor 30 is lower than a predetermined value, and when the humidity is higher than the predetermined value, the reliability increases as the humidity increases. Decreases and is not measurable (correction value 0) when the value exceeds the measurement limit value. Since the urination action is a temporary action, the humidity correction table is “partial correction” for correcting only the period during which the change in humidity measured by the humidity sensor 30 is observed. Note that, hereinafter, the correction of the reliability only in a specific period of the defecation period, or the correction of the whole defecation period, but the correction different in each period of the defecation period is referred to as “partial correction”.

  In addition, the semiconductor gas sensor used as the odorous gas sensor 26 is configured to emit odorous gas based on the oxidation / reduction reaction of oxygen and reducing gas adsorbed on the surface in a state where the detection unit made of tin oxide is heated. Detected. For this reason, when the temperature of a detection part is higher or lower than a predetermined temperature range, sensor sensitivity will fall. For this reason, as shown in FIG. 15, in the temperature correction table, a correction value is determined according to the temperature detected by the temperature sensor 32. Specifically, when the temperature detected by the temperature sensor 32 is within an appropriate temperature range suitable for the measurement of the detection unit of the odorous gas sensor 26, the correction value is a value larger than 1 so as to increase the reliability. If the temperature detected by the temperature sensor 32 is slightly higher or lower than the appropriate temperature range, the correction value is set to a value less than 1 so as to decrease the reliability value, and further, detected by the temperature sensor. When the measured temperature is larger than the upper limit value of the measurable temperature or smaller than the lower limit value of the measurable temperature, the measurement is impossible (correction value 0). The temperature correction does not vary greatly during the defecation period, and is therefore an overall correction for correcting the entire defecation period.

  In addition, as described above, when performing the excretion action a plurality of times during a single defecation period, the amount of defecation gas itself is large (the amount of odorous gas is also large) in the first defecation period. The initial excretion action is more accurate than the later excretion action. For this reason, as shown in FIG. 16, in the excretion action frequency correction table, the first defecation gas correction value is set to a value larger than 1 so as to increase the reliability value, the second time is set to 1, and the third time and thereafter. The value was less than 1 and gradually decreased as the number of times increased. Thus, the first defecation gas is devised so as to be preferentially diagnosed. The excretion action frequency correction table corrects only the period during which defecation gas is detected and is a partial correction.

As shown in FIG. 12, when the entrance detection sensor 34 detects the entrance of the subject at time t ₁ , the control device 22 of the measurement device 6 shifts from the pre-measurement environment maintenance process in the standby state to the measurement start preparation process. Then, the sensor heating heater 54 and the suction device 18 are driven. Thereby, the temperature detected by the temperature sensor 32 rises and converges to an appropriate temperature. Then, the data analysis device 60 of the remote controller 8 refers to the temperature correction table and refers to the correction value corresponding to the convergence temperature measured by the temperature sensor 32 during the non-defecation period before the seating detection sensor 36 detects the seating. To get. In the example shown in FIG. 12, the temperature correction value is 0.9.

Also. When the subject enters the room at time t ₁ , the detection data detected by the odorous gas sensor 26 increases due to the strange odor noise attached to the subject, and then converges to a certain value. Then, the seating by the seating detection sensor 36 at time t ₂ is detected. The data analysis device 60 of the remote controller 8 obtains a correction value corresponding to the detection data measured by the odorous gas sensor 26 in the non-defecation period before the seating detection sensor 36 detects the seating. In the present embodiment, the test subject adhesion odor gas noise correction value is 0.7.

Next, at time t ₃ , when the subject urinates during the defecation period after the seating detection sensor 36 detects the seating, the detection value by the humidity sensor 30 increases. The humidity increase detected by the humidity sensor 30 may be measured, for example, based on the humidity before the defecation period, that is, before the seating detection sensor 36 detects the seating. As described above, when an increase in the detection data is detected by the humidity sensor 30, the data analysis device 60 refers to the humidity correction table for the period during which the detection data is increasing, and corresponds to the increased detection data. Find the correction value. In the present embodiment, the partial correction value during the period in which the detection data from the humidity sensor 30 rises (that is, times t _{3 to} t ₄ ) is 0.6.

Next, when the subject performs an excretion action at times t ₅ and t ₆ , the change rate of the difference between the detection data detected by the odorous gas sensor 26 and the reference value is equal to or greater than a predetermined value. The analysis device 60 calculates the amount of gas accompanying this excretion action. At the same time, the data analysis device 60 refers to the frequency correction table according to the number of excretion actions within the defecation period, and the period corresponding to the first excretion action (that is, times t _{5 to} t ₅ ′) The correction value becomes 1.5, and the period corresponding to the second excretion action (that is, time t _{6 to} t ₆ ′) becomes the correction value 1.0.

  The data analysis device 60 calculates the measurement reliability of gas detection associated with each excretion based on the overall correction value and the partial correction value estimated in this way. In the present embodiment, the reliability is based on 3, and the reliability for each excretion is calculated as 3 × the product of all the total correction values × the product of all the corresponding partial correction values. Specifically, the reliability of the first excretion is 3 (reference) × 0.9 (temperature correction value) × 0.7 (subject adhesion noise correction value × 1.5 (number of times correction value) = 2.84. The reliability of the second excretion action is 3 (reference) × 0.9 (temperature correction value) × 0.7 (subject adhesion noise correction value × 1.0 (number of times correction value) = 1. 89.

Then, the reliability calculated in this way is displayed on the display device 68 of the remote controller 8 as described with reference to FIG. Further, the calculated reliability is transmitted from the subject apparatus to the server 12 together with the detection data of the odorous gas sensor 26 and the detection data of the hydrogen gas sensor 24, and is recorded in the defecation gas database of the server 12. At this time, raw data that is not corrected by reliability described later is recorded in the stool gas database of the server 12 as the detection data of the odor gas sensor and the detection data of the hydrogen gas sensor.
When the measurement data is browsed by the medical institution terminal 16 connected to the server 12, the measurement reliability is displayed together with the detection data of the odorous gas sensor 26 and the detection data of the hydrogen gas sensor 24. The doctor of the medical institution makes a diagnosis with reference to the measurement reliability displayed together with the odorous gas and hydrogen gas displayed on the medical institution terminal 16. Thereby, when a doctor etc. diagnoses a test subject's physical condition based on measurement data, a more exact diagnosis can be performed using data with high measurement reliability. In addition, the doctor may make a diagnosis without using or placing importance on data with low measurement reliability. Note that when the reliability of a part or all of the measurement data is 1 or less, the measurement accuracy is very low. Therefore, the measurement data is not transmitted to the server 12 because measurement is impossible.

  Further, the measurement reliability calculated in this way can be used as one of predetermined first predetermined conditions, and the detection data of the odorous gas sensor 26 and the hydrogen gas sensor 24 can be corrected based on this. . Specifically, when the measurement reliability is high, an actual detection value is used, but when the measurement reliability is low, the detection value is close to a past detection value (for example, a history representative value). The past history is corrected as follows. As an example, when analyzing the physical condition based on the defecation gas detection data associated with the first excretion action in the subject-side device 10, a new detection is performed so as to approach the past measurement data recorded in the storage device of the remote controller 8. A case where the detected value is corrected will be described. As described above, the reliability associated with the first excretion was calculated as 2.84.

  The data analysis device 60 determines the past history correction amount of the measurement value by the past history correction based on the reliability calculated in this way. FIG. 17 is a diagram showing a correction table showing the relationship between the reliability recorded in the data analysis device and the correction rate of the measured value. As shown in the figure, for example, in the present embodiment, when the reliability is 1 or less, the reliability of the detection data is too low, so that it corresponds to one of the predetermined second predetermined conditions. The measured value is disabled. That is, the physical condition is not analyzed based on the detection data during the period when the reliability is equal to or less than the predetermined value, and the analysis is performed based only on the detection data having the reliability higher than the predetermined value, and the analysis result is displayed on the display device 68. If the reliability is greater than 1 and less than or equal to 2, past history correction is performed to bring the measured value closer to the past history side by 20%. That is, the past history correction amount is calculated as a distance (= 0.2D) corresponding to 20% of the distance D between the plot point of the current detection data and the history representative value. If the reliability of the measured value is greater than 2 and less than or equal to 3, the past history correction amount is calculated as a distance corresponding to 15% of the distance D (= 0.15D). If the reliability is greater than 3 and less than or equal to 4, the past history correction amount is calculated as a distance corresponding to 10% of the distance D (= 0.1D). Furthermore, when the reliability is greater than 4 and less than or equal to 5, the past history correction amount is calculated as a distance corresponding to 5% of the distance D (= 0.05D). If the measured value is greater than 5, the past history correction amount is set to 0.

  In the above example, the reliability associated with the first excretion action is 2.84. For this reason, as described with reference to FIG. 7A, correction (past history correction amount = 0.15 × D) is performed so that the plot point of the latest data approaches 15% of the past measurement value, Display with past data.

  Such correction based on reliability may be performed on the server 12 side. In addition, when analyzing the physical condition on the server 12 side, for example, the detection value of the odorous gas and the detection value of the hydrogen gas of the excretion action whose reliability is equal to or higher than a predetermined value in one defecation period are totaled. The physical condition may be analyzed based on the totaled data. In addition, the detection data stored in the storage device of the remote controller 8 does not necessarily have to be corrected based on the measurement reliability, and the corrected detection data may be recorded.

Further, in the present embodiment, the past history correction amount determined based on FIG. 17 is changed depending on the stool state over time analyzed by the stool state analyzing unit 60a.
FIG. 18 to FIG. 22 are tables showing correction coefficients for changing the past history correction amount according to changes in the fecal state over time.
In addition, when the subject is shallow after the use of the biological information measurement system 1 is started and the stool state data such as “daily stool frequency” has not been accumulated for a predetermined accumulation period or longer, the stool state is entered. The past history correction amount based on the change is not executed. On the other hand, the result of the stool state physical condition analysis (FIG. 8) is displayed together with the start of use of the biological information measurement system 1 by the subject even in the state where the stool state data is not accumulated. In this embodiment, the subject starts using the biological information measurement system 1, and after the fecal state data has been accumulated in the storage device 60c for a predetermined accumulation period (30 days in the present embodiment) or more, the time course The correction for the result of the gas physical condition analysis is executed based on the stool condition.

  FIG. 18 is a table of long-term defecation frequency correction coefficients set based on the daily defecation frequency. The subject's “daily defecation frequency” is moving averaged over the past month, and a long-term defecation frequency correction coefficient is set according to this value. In the example shown in FIG. 18, the long-term defecation frequency correction coefficient is 1 when the moving average of “daily defecation frequency” is less than 1.1 times. Furthermore, the long-term defecation frequency correction coefficient is 0.8 when the moving average is 1.1 times or more and less than 1.5 times, and 0.7 or 2 times when the moving average is 1.5 times or more and less than 2 times. In this case, it is set to 0.1. Since this long-term defecation frequency correction coefficient is multiplied by the past history correction amount, the correction amount decreases as the defecation abnormality occurs as the “daily defecation frequency” increases. As a result, the distance that brings the current detection value closer to the past history representative value is shortened, and when the current detection value indicates poor physical condition, the state is displayed on the display device 68 more directly. Become.

  Next, FIG. 19 is a table of long-term total defecation amount correction coefficients set based on one total defecation amount. The subject's “total amount of defecation” is subjected to a moving average over the past one month, and a long-term total defecation amount correction coefficient is set according to this value. In the example shown in FIG. 19, the long-term total defecation amount correction coefficient is 1 when the moving average of the “total defecation amount of one time” is larger than 90% of the appropriate amount (for example, 130 grams). Further, the long-term total defecation amount correction coefficient is 0.7 when the moving average is more than 85% of the appropriate amount and 90% or less, and 0.5 when the moving average is more than 75% and less than 85% of the appropriate amount. If it is 75% or less of the appropriate amount, it is set to 0.1. Since the long-term total defecation amount correction coefficient is multiplied by the past history correction amount, the correction amount decreases as the defecation abnormality occurs because the subject's “total amount of defecation” is small.

  Next, FIG. 20 is a table of long-term excretion correction coefficients set based on one excretion. The subject's “one-time excretion amount” is subjected to a moving average over the past one month, and a long-term excretion correction coefficient is set according to this value. In the example shown in FIG. 20, the long-term excretion correction coefficient is 1 when the moving average of “one excretion” is greater than 85% of the appropriate amount (for example, 50 grams). Furthermore, the long-term excretion correction coefficient is 0.7 when the moving average is more than 75% of the appropriate amount and not more than 85%, 0.5 when the moving average is more than 65% and not more than 75% of the appropriate amount, When it is 65% or less of the appropriate amount, it is set to 0.1. Since this long-term excretion correction coefficient is multiplied by the past history correction amount, the correction amount decreases as the subject's “one-time excretion amount” is small and defecation abnormality occurs.

  Next, FIG. 21 is a table of long-term constipation frequency correction coefficients set based on the daily defecation frequency. The subject's “daily stool frequency” is moving averaged over the last one month, and a long-term constipation frequency correction coefficient is set according to this value. In the example shown in FIG. 21, the long-term constipation frequency correction coefficient is 1 when the moving average of “daily defecation frequency” is at least once a day. Furthermore, the long-term constipation frequency correction coefficient is 0.9 when the moving average is less than once a day and less than once every two days, and less than once every two days. In the case of more than once, 0.8 is set, and in the case where the moving average is less than once in 3 days, it is set to 0.6. Since the long-term constipation frequency correction coefficient is multiplied by the past history correction amount, the correction amount decreases as the “daily stool frequency” of the subject is small and the bowel abnormality (constipation state) occurs.

  Next, FIG. 22 is a table of long-term soft stool frequency correction coefficients set based on soft stool conditions. The subject's “number of soft stools” is summed over the last one month, and a long-term soft stool frequency correction coefficient is set according to this value. In the example shown in FIG. 22, the long-term soft stool frequency correction coefficient is 1 when the number of soft stools in the most recent past month is less than five. Furthermore, the long-term soft stool frequency correction coefficient is 0.7 when the number of soft stools is 5 times or more and less than 8 times, 0.5 when the number of soft stools is 8 times or more and less than 11 times, and the number of soft stools Is set to 0.1 when the number is 11 times or more. Since this long-term soft stool frequency correction coefficient is multiplied by the past history correction amount, the correction amount decreases as the number of “soft stools” of the subject increases and the bowel abnormality (soft stool state) occurs.

  The past history correction amount for correcting the analysis result based on the current detection data so as to approach the history representative value is determined based on the reliability based on the distance D between the plot point of the current detection data and the history representative value. And the above-mentioned “long-term defecation frequency correction coefficient”, “long-term total defecation amount correction coefficient”, “long-term excretion amount correction coefficient”, “long-term constipation frequency correction coefficient”, and “long-term soft stool frequency correction coefficient” ”To calculate. As described above, the past history correction amount is to bring the result of the gas physical condition analysis based on the current measurement (detection data) closer to the past history representative value, but this past history correction amount is corrected based on the fecal state, Be changed. For example, as illustrated in FIG. 17, the reliability is calculated as 2.84, “long-term defecation frequency correction coefficient”, “long-term total defecation amount correction coefficient”, “long-term excretion amount correction coefficient”, “long-term constipation frequency correction” When the “coefficient” and “long-term soft stool frequency correction coefficient” are 1, 1, 1, 0.8, and 1, respectively, the past history correction amount is 0.15 × D × (1 × 1 × 1 × 0). .8 × 1). That is, the analysis result correction unit 60b corrects the result of the gas physical condition analysis based on the detection data regarding the odorous gas based on the stool state with time stored in the stool state storage device 60c.

  As described above, the correction based on the reliability is the latest in order to prevent the analysis result of the physical condition from swinging to the unhealthy side due to detection data with low reliability, and causing an unnecessary burden on the subject. The result of the gas physical condition analysis based on the detection data is brought closer to the past measurement data (past history representative value) side. However, if the analysis result based on the stool condition is not good and there is a defecation abnormality, it is certain that there is some physical condition, so change the past history correction amount to reduce the latest gas Allow the result of physical condition analysis to swing to some extent unhealthy. As a result, the subject can be made to recognize at an early stage that his / her physical condition has deteriorated, and the lifestyle can be improved and the patient can be urged to go to the hospital.

  In the above, as the correction table for the reliability correction, the test subject adhered odor gas noise correction table (FIG. 13), the humidity correction table (FIG. 14), the temperature correction table (FIG. 15), and the excretion action frequency correction table (FIG. 16). Although explained, the correction table for reliability correction is not limited to these. 23 to 35 are diagrams illustrating examples of other correction tables.

  For example, if there is a strange odor noise (environmental noise) other than the defecation gas such as a fragrance in the toilet room, the odorous gas sensor 26 may detect this strange odor noise and the measurement accuracy may be reduced. Therefore, the data analysis device 60 corrects the reliability in order to evaluate the influence of environmental noise. In addition, about the noise amount of such environmental noise, it can evaluate based on the detection data by the odorous gas sensor 26 before a test subject's entrance is detected by the entrance detection sensor 34, for example. FIG. 23 is a diagram showing an environmental noise correction table. As shown in the figure, the environmental noise correction value is 1 when the environmental noise amount is smaller than a predetermined value, and is corrected to lower the reliability value as the environmental noise amount becomes larger than the predetermined value. Decrease the coefficient. When the amount of environmental noise is equal to or greater than the measurable upper limit value, it is determined that measurement is impossible because it corresponds to one of predetermined second predetermined conditions. The environmental noise correction value affects the entire defecation period, and therefore may be a total correction.

  In addition, for example, when the reference value is set, such as when a spray-type fragrance is used, the detection data of the odorous gas sensor 26 greatly fluctuates, or the reference value set when the gas amount is estimated. When the inclination is large, the accuracy of the estimated gas amount is lowered. Therefore, the data analysis device 60 refers to the reference value stability correction table, and corrects the reliability in order to evaluate the influence of such a reference value stability failure state (referred to as a reference value stability failure). The reference value stability can be evaluated based on, for example, the inclination of the reference value with respect to the time axis during the non-defecation period and the magnitude of fluctuation in the detection value of the odorous gas sensor 26 when setting the reference value. FIG. 24 is a diagram illustrating a reference value stability correction table. As shown in the figure, the reference value stability noise correction value is 1 when the reference value stability failure is small, and decreases as the reference value stability failure increases. When the reference value stability failure is equal to or greater than a predetermined value, it is determined that measurement is not possible because one of the predetermined second predetermined conditions is satisfied. In addition, since estimation of the gas amount sets a reference value for each excretion action, it is a correction value only for a period corresponding to each excretion action, that is, a partial correction.

  For example, when the toilet seat is washed with a sterilization sheet, the odorous gas sensor 26 detects a component such as alcohol contained in the sterilization sheet. As for the influence of components such as alcohol contained in the sterilization sheet, a large value is detected in the odor gas sensor 26 immediately after the use of the sterilization sheet. However, since alcohol is highly volatile, it is odorous in a short period of time. The value detected by the gas sensor 26 is lowered. Therefore, the data analysis device 60 refers to the sanitized toilet seat cleaning correction table and corrects the reliability according to the influence of toilet seat sanitization. The use of the sterilization sheet is, for example, detected by the odorous gas sensor 26 after detecting that the subject has entered the room by the room detection sensor 34 and before detecting that the subject has been seated by the seating detection sensor 36. It can be detected by detecting that the data fluctuates more than a predetermined value. FIG. 25 is a diagram showing a sanitized toilet seat cleaning correction table. When it is detected that the sterilization sheet is used in this way, it is impossible to measure for a predetermined period from the detection of the sterilization sheet, assuming that one of the predetermined second predetermined conditions is satisfied (correction value 0). ), And the correction value for the subsequent period increases from a value less than 1 to 1 over time. In addition, since the influence of a disinfection sheet changes with time as above-mentioned, it is set as partial correction | amendment.

  Further, since the amount of odorous gas contained in the defecation gas is very small, the more odorous gas discharged within the defecation period, the more accurate physical condition analysis can be performed. Therefore, the data analysis device 60 refers to the defecation gas total amount correction value table and corrects the reliability based on the total amount of odorous gas. The total amount of defecation gas can be evaluated by the total amount of gas estimated based on the detection data of the odorous gas sensor within the defecation period. FIG. 26 is a diagram illustrating a defecation gas total amount correction value table. As shown in the figure, the defecation total amount correction value is a predetermined second because the defecation gas total amount is greater than or equal to a predetermined value, because it is considered that some problem has occurred, such as spraying a fragrance spray during measurement. If the total amount of defecation gas is less than or equal to the predetermined value, the amount of defecation gas is so small that accurate measurement cannot be performed. In addition, the measurement is not possible (correction value 0) as one of the second predetermined conditions. Then, within a range where it is not determined that measurement is impossible (correction value 0), if the defecation gas total amount is large, the correction value is set to 1, and the correction value decreases as the defecation gas total amount decreases. Note that the total defecation gas amount correction is a total correction because a correction value is set based on the total defecation gas amount for the entire defecation period.

  Moreover, since a large amount of defecation gas is released into the bowl at the farting time than at the time of defecation, the defecation gas by the farting is suitable for physical condition analysis. For this reason, when the fart by the subject is detected, the data analysis device 60 refers to the fart correction value table and corrects the reliability in the fart period based on the amount of defecation gas included in the fart. To do. As for fart action, when the seat detection is detected by the seat detection sensor 36, it is detected that the difference between the detected value of the odorous gas sensor 26 and the reference value has rapidly increased at a change rate of a predetermined value or more. In addition, it can be determined that a fart act has been performed. Further, the period from when the above-mentioned difference suddenly increases until the detection value of the gas sensor 26 returns to the reference value may be a fart period. In order to detect that a fart action has been performed more accurately, the detection data of the odorous gas sensor 26 rises rapidly at a rate of change of a predetermined value or more, and the stool is placed in the bowl by a sealed water amount sensor or the like. What is necessary is just to detect that it is not discharged | emitted. FIG. 27 is a diagram illustrating a fart correction value table. As shown in the figure, in the fart correction value table, when the fart gas amount (the amount of stool gas detected by the odorous gas sensor) is small, the correction value is 1, and the fart gas amount increases as the fart gas amount increases. The correction value may be set to increase.

  In addition, when there is a large amount of stool in each excretion act, the amount of defecation gas increases and a more accurate physical condition analysis can be performed. The amount is reduced and the accuracy of physical condition analysis is reduced. Therefore, the data analysis device 60 refers to the stool volume correction value table and corrects the reliability based on the stool volume during each excretion action. The stool volume can be evaluated by, for example, a sealed water volume sensor (stool volume measuring device) that detects a change in the sealed water volume of the defecation / urine detection sensor 38. FIG. 28 is a diagram showing a stool amount correction value table. As shown in the figure, when the stool volume is equal to or less than a predetermined value, the amount of defecation gas as well as the stool volume is very small, and accurate analysis cannot be performed. Measurement is not possible as it falls under one. When the stool volume exceeds a predetermined value, the correction value gradually increases from a value less than 1 to a value greater than 1 as the stool volume increases. Since the stool volume is determined for each excretion action, the stool volume correction value is a partial correction.

  In addition, for example, when the stool is in a diarrhea state, since the release time is short, the sensor cannot sufficiently detect defecation gas. Moreover, when the stool after defecation floats in the sealing water, the defecation gas is released from the stool that floats in the sealing water, and the detection accuracy of the defecation gas decreases. Therefore, the data analysis device 60 refers to the flight type correction table and corrects the reliability according to the flight type of each excretion action. Note that the stool type can be detected based on the detection results using a CCD of a defecation / urine detection sensor 38 as a stool state detection device, a microwave sensor, or the like. In addition, feces floating can be detected by installing a CCD, a microwave sensor or the like in the bowl as a floating detector. FIG. 29 is a diagram illustrating a flight type correction value table. As shown in the figure, in the case of diarrheal stool, the measurement is impossible (correction value 0) as one of the predetermined second predetermined conditions, and when floating stool is detected, The correction value in the subsequent excretion action is set to a value less than 1, and the correction value is set to 1 when normal stool is detected. In addition, since a flight type is determined for every excretion action, the flight type correction value is a partial correction. In addition, when the subject's diarrhea is detected and measurement is impossible, the display device 68 displays a message “The physical condition is not measured because it seems to have diarrhea”, and the physical condition is analyzed. The normal display of results is not made.

  Also, healthy people usually defecate about once a day. On the other hand, if the gastrointestinal condition worsens due to food poisoning or the like, defecation may occur several times a day. In such a case, even if defecation is performed, the amount of defecation gas released during defecation is reduced. In addition, when the frequency of defecation decreases due to constipation or the like, the amount of defecation gas increases because the generation time of the odor component increases or the amount of stool increases. If the defecation interval becomes too large, the analysis accuracy of the physical condition is lowered. Therefore, the data analysis device 60 refers to the defecation interval correction table and corrects the reliability based on the defecation interval. The defecation interval can be determined based on the date and time of the previous defecation stored by the data analysis device 60 and the defecation history information input in the measurement start preparation step S2. FIG. 30 is a diagram illustrating a defecation interval correction value table. As shown in the figure, when the defecation interval is extremely short, the correction value is very lower than 1, and when the defecation interval is about one day, the correction value is 1, and the defecation interval is 2. When it is about days, the correction value is set to a value lower than 1, and when the defecation interval is 4 days or more, the correction value is set to a value much lower than 1. The defecation interval correction value is the overall correction.

  In the determination of the physical condition based on the defecation gas, for example, when the gastrointestinal condition is deteriorated due to the cause of eating and drinking over the previous day, the physical condition is determined to be worse than the original physical condition. For this reason, the daily life results in variations in the physical condition analysis results. For this reason, for example, at the time when the analysis of physical condition by the biological information measurement system of the present embodiment is started, if a day with a bad physical condition happens to overlap due to overdrinking and eating, etc., an analysis result with a poor physical condition even if the history is displayed Only the message is displayed, and there is a possibility that accurate determination of the disease cannot be performed in a medical institution or the like. Therefore, the data analysis device 60 corrects the reliability according to the number of past measurement data of the subject stored in the subject-side device with reference to the data accumulation amount correction table. FIG. 31 is a diagram showing a data accumulation amount correction table. As shown in the figure, when the number of accumulated data is less than 5, diagnosis is impossible (correction value 0), and when the number of accumulated data is 5 times or more and less than 10, the correction value is 1 If the number of stored data is 10 times or more and less than 30 times, the correction value is set to a low value of less than 1, and if the number of stored data is 30 times or more, the correction value is corrected. The value is 1. The data accumulation amount correction value is assumed to be overall correction.

  That is, when the number of accumulated data is less than 5, it is determined that the predetermined third predetermined condition is satisfied, and plot points based on the current detection data are not displayed. However, detection data corrected by other reliability correction values is stored and accumulated in the storage device (FIG. 2) of the subject apparatus. For this reason, until the physical condition measurement regarding the subject reaches five times, the analysis result of the physical condition is not displayed on the display device 68, and the detection data is stored in the storage device. Thus, the subject-side device in the present embodiment is not a device for diagnosing cancer, but intended to have the subject recognize that the risk of cancer has increased with changes in physical condition and to improve life. Device. For this reason, since the accuracy of one measurement is not high, and the change history is the value of this apparatus, it is desirable to take such measures in order to prevent unnecessary psychological burdens.

  When the filter 72 installed in the duct 18a is clogged, the amount of air sucked into the duct 18a is reduced. On the other hand, if the air volume of the gas sent to the odorous gas sensor 26 or the hydrogen gas sensor 24 changes, the detection data of the odorous gas sensor 26 or the hydrogen gas sensor 24 changes according to the air volume. Further, if the wind speed of the gas sent to the odorous gas sensor 26 or the hydrogen gas sensor 24 is high, the time for which the gas contacts the sensor is short, and the detection part of the sensor does not react sufficiently. For this reason, it is desirable that the amount of air sent to the odorous gas sensor 26 and the hydrogen gas sensor 24 is constant. For this reason, the data analysis device 60 refers to the air volume correction value table and corrects the reliability according to the air volume (wind speed) of the gas sent to the odorous gas sensor 26 or the hydrogen gas sensor 24. In addition, the gas | air volume can be estimated based on the electric current and voltage of the suction fan 18c provided in the deodorizing apparatus, for example. FIG. 32 is a diagram showing an air volume correction value table. As shown in the figure, in the air volume correction table, when the air volume is less than the measurable lower limit value and greater than or equal to the measurable upper limit value, it is determined that one of the predetermined second predetermined conditions is met and measurement is not possible ( The correction value is 0), the correction value is larger than 1 when the air volume is in the optimum range, and is close to 1 within the other measurable range. In the present embodiment, since the influence of the decrease in the air volume due to clogging has a greater influence on the sensor detection sensitivity than when the air volume is large, the correction value in the range higher than the optimum range within the measurable range is The correction value in the range lower than the optimum range is set low. Since the air volume during the measurement does not change greatly, the overall correction is made.

The defecation gas contains CO ₂ gas as a health gas, like hydrogen gas. For this reason, when a large amount of CO ₂ is detected by the CO ₂ gas sensor, the defecation gas is reliably detected by the sensor device. Therefore, the data analysis device 60 refers to the CO ₂ correction table and corrects the reliability based on the CO ₂ detection data detected by the carbon dioxide sensor 28. FIG. 33 shows a CO ₂ correction table. As shown in the figure, in the CO ₂ correction table, when the detected amount of CO ₂ is less than a predetermined value, the correction value is set to 1, and when the detected amount of CO ₂ is greater than or equal to the predetermined value, it increases. The correction value is increased. Since the CO ₂ correction value can be calculated for each excretion action, it is a partial correction. Thus, in the present embodiment, since the detected hydrogen gas is corrected based on the amount of CO ₂ gas, the health system gas is evaluated using hydrogen gas and CO ₂ gas.
Further, when the physical condition analysis is performed using the detection data of the CO ₂ gas sensor as the detection data of the health gas, the correction value increases as the detection value detected by the hydrogen gas sensor 24 increases instead of the CO ₂ correction table. It is sufficient to use an H ₂ correction table that increases the value.

  The defecation gas contains methane as a health gas, like hydrogen gas. For this reason, for example, a methane gas sensor that reacts strongly with methane gas is installed in the duct 18a of the deodorization device, and when a large amount of methane is detected by this methane gas sensor, a large amount of defecation gas is released. Therefore, the data analysis device 60 refers to the methane gas correction table and corrects the reliability based on the detected amount of methane gas detected by the methane gas sensor. FIG. 34 shows a methane gas correction table. As shown in the figure, in the methane gas correction table, when the detected amount of methane gas is less than a predetermined value, the correction value is 1, and when the detected amount of methane gas is greater than or equal to the predetermined value, the correction value increases as it increases. Is getting bigger. Since the methane gas correction value can be calculated for each excretion action, it is a partial correction.

In this embodiment, when the detected values of CO ₂ and methane are high, the reliability is corrected to be high. However, the present invention is not limited to this, and when the detected values of CO ₂ and methane are high, the hydrogen gas It is also possible to perform correction so as to increase the detection value.

  When there is cancer in the intestine, not only odorous gas but also hydrogen sulfide gas is included in the defecation gas. For this reason, for example, a hydrogen sulfide gas sensor that reacts strongly with hydrogen sulfide gas is installed in the duct 18a of the deodorizer, and the reliability is determined based on the detection data of the hydrogen sulfide gas detected by the hydrogen sulfide gas sensor. to correct. FIG. 35 is a diagram showing a hydrogen sulfide gas correction table. As shown in the figure, in the hydrogen sulfide gas correction table, the correction value is set to 1 when the detected amount of sulfide gas is less than a predetermined value, and increases when the detected amount of hydrogen sulfide gas is equal to or greater than the predetermined value. The correction value is increased as time goes on. Since the hydrogen sulfide gas correction value can be calculated for each excretion action, it is a partial correction. The reliability is calculated using a part or all of the correction table described above.

  Next, with reference to FIG. 36 and FIG. 37, the direct correction | amendment based on the feces state of the result of a gas physical condition analysis is demonstrated. The correction of the result of the gas physical condition analysis described with reference to FIGS. 13 to 35 is to correct the past history of the result of the gas physical condition analysis based on the detection data of the odorous gas sensor 26 based on the reliability of the detection data. The correction amount of the past history correction has been changed based on the flight status. The correction described below is to directly correct the result of the gas physical condition analysis based on the fecal state.

  The biological information measurement system 1 of the present embodiment measures the odorous gas that indicates a poor physical condition of the subject and the health gas (such as hydrogen gas) that indicates that the subject is in good condition over time, thereby measuring the subject. It is intended to evaluate the physical condition of. In this biological information measurement system 1, in the region where the subject's physical condition is good to some extent, the amount of odorous gas is small and the amount of health gas is large, so the result of the physical condition analysis of the subject can be easily presented. On the other hand, if the physical condition of the subject deteriorates to some extent, it is necessary to present the result of the physical condition analysis carefully. That is, when the physical condition of the subject deteriorates to some extent, the amount of odorous gas increases and the amount of healthy gas decreases, but as described above, odorous gas is caused by temporary physical condition deterioration or noise caused by the measurement environment. May also increase. For this reason, if the increase in odorous gas is presented to the subject as a result of the physical condition analysis as it is, the analysis result indicating that the subject is unhealthy by mistake is presented to a healthy subject, which may cause an unnecessary psychological burden on the subject. There is.

  In order to solve this problem, in the present embodiment, past history correction is performed based on the reliability of the detected data, and the displayed gas physical condition analysis result is prevented from swinging largely unhealthy in a short period of time. ing. However, if the fluctuation of the gas physical condition analysis result is excessively suppressed by past history correction, the subject may be slow to recognize a disease such as colorectal cancer, and the disease may be advanced. Therefore, in the present embodiment, in the situation where the physical condition of the subject has deteriorated to some extent as a result of the stool state physical condition analysis, the result of the gas physical condition analysis is directly corrected based on the stool state, and a bowel abnormality is recognized Corrects the result of gas physical condition analysis to the side of poor physical condition at an early stage to alert the subject. Here, since the result of the stool state physical condition analysis is also a subject having subjective symptoms, the result of the gas physical condition analysis is corrected based on the defecation abnormality, and a concern about a disease such as colorectal cancer is erroneously notified. Even so, the subject does not feel a strong sense of incongruity.

FIG. 36 is a diagram for explaining the direct correction of the result of the gas physical condition analysis, and FIG. 37 is a flowchart showing the direct correction process based on the fecal state of the result of the gas physical condition analysis.
In the direct correction of the gas physical condition analysis result described here, the physical condition level of the subject based on the fecal state physical condition analysis is determined using the table of correction coefficients based on the fecal state shown in FIGS. Based on the determination result, the correction amount for the result of the gas physical condition analysis is changed. For example, when the “daily stool frequency” shown in FIG. 18 is 1.5 times or more and less than 2 times, the level of poor physical condition based on the stool state is determined as “level 2”, and when it is 2 times or more Is determined to be “level 3”. Similarly, “total amount of defecation” (FIG. 19), “amount of excretion once” (FIG. 20), “frequency of defecation per day” (FIG. 21), and “number of times of loose stool” (FIG. 22) Based on this, the level of poor physical condition based on the fecal state is determined.

  In addition, when a test subject has started to use the biological information measurement system 1 and the day is shallow and sufficient fecal state data has not been collected, the direct correction of the gas physical condition analysis based on the fecal state is not performed. On the other hand, the result of the stool state physical condition analysis (FIG. 8) is displayed from the start of use of the biological information measurement system 1 by the subject. In the present embodiment, when the subject starts using the biological information measurement system 1 and the detection data for the past 30 times are collected, direct correction of the gas physical condition analysis is executed.

First, in step S1 of FIG. 37, the level of poor physical condition based on the fecal state is determined. That is, any one of “daily defecation frequency”, “total defecation volume”, “excretion volume”, “daily defecation frequency”, or “number of soft stools” is “level 3”. It is determined whether or not there is. If any one of the flight statuses is “level 3”, the process proceeds to step S8. Otherwise, the process proceeds to step S3.
Next, in step S3, it is determined whether or not any one of the above-mentioned flight states is “level 2”. If any one of the flight statuses is “level 2”, the process proceeds to step S5. Otherwise, the process proceeds to step S4.
In step S4, the correction of the gas physical condition analysis result based on the stool state is not executed, and one process of the flowchart of FIG. 37 is terminated.

  On the other hand, if it is determined in step S3 that one of the above-mentioned flight statuses is “level 2”, the process proceeds to step S5, and in step S5, is there two or more “level 2”? It is determined whether or not. When there is one “level 2”, the process proceeds to step S6, and when there are two or more, the process proceeds to step S7.

In step S6, correction is performed to move the history representative value G, which is the center of gravity of the detection data for the past month, by 5% toward the unhealthy (physical condition) side. Here, the detection data for the past month of the odorous gas and the health gas are dispersed on the physical condition display table, and the center of gravity of the dispersed detection data is the history representative value G. In the present embodiment, as shown in FIG. 36, this history representative value G is set to 5% of the standard deviation of the detected data, and the poor physical condition side (the direction of the arrow on the physical condition display table in FIG. 36 (upper left direction). )). That is, when the coordinates of the history representative value G are (X _G , Y _G ) and the coordinates of the past detection data are (X _i , Y _i ), the standard deviation (σ _X , σ _Y ) of the detection data is ,Respectively,
Is calculated by The history representative value G is moved toward the poor physical condition by 5% of these standard deviations. Accordingly, the coordinates (X _G , Y _G ) of the history representative value G are moved to (X _G −0.05σ _X , Y _G + 0.05σ _Y ) by correction based on the fecal state.

  Thus, when the result of the stool state physical condition analysis based on the stool state deteriorates to a predetermined physical condition level or more, the gas physical condition analysis result is corrected in the direction of poor physical condition. That is, the history representative value G based on the gas physical condition analysis based on the odorous gas is moved to the poor physical condition side, and the moved history representative value G is displayed on the display device 68. By moving the history representative value G, thereafter, any detection data corrected by past history correction is corrected to the side of poor physical condition as compared to the case where the history representative value G is not moved. This is because in the situation where the subject has some defecation abnormality and the result of the stool state physical condition analysis is worse than the predetermined physical condition level, even if no abnormality appears in the gas physical condition analysis based on the odorous gas analysis, This is based on the inventor's knowledge that poor physical condition is strongly suspected. For example, if a subject has a large intestine polyp, in many cases some defecation abnormalities appear, but the odor gas does not increase so much until this polyp becomes cancerous. As in this embodiment, by correcting the result of the gas physical condition analysis based on the stool state, it is possible to make the subject recognize poor physical condition in the previous stage in which the odorous gas greatly increases due to colorectal cancer, The reliability of physical condition measurement can be further improved.

On the other hand, if it is determined in step S5 that there are two or more “level 2”, the process proceeds to step S7. In step S7, correction is performed to move the history representative value G, which is the center of gravity of the detection data for the past month, by 10% toward the unhealthy (physical condition) side. That is, assuming that the coordinates of the history representative value G are (X _G , Y _G ) and the standard deviation of the detected data is (σ _X , σ _Y ), the history representative value G is (X _G − 0.1σ _X , Y _G + 0.1σ _Y ). As described above, when the result of the stool condition physical condition analysis based on the stool condition deteriorates beyond a predetermined physical condition level, the analysis result correcting unit 60b increases the correction amount for correcting the gas physical condition analysis result in the direction of poor physical condition. Let

On the other hand, if it is determined that “level 3” exists in step S1 of FIG. 37 and it is determined in step S8 that there are not two or more “level 3”, the process proceeds to step S9. In step S9, correction is performed by moving the history representative value G, which is the center of gravity of the detection data for the past month, by 20% toward the unhealthy (physical condition) side. That is, assuming that the coordinates of the history representative value G are (X _G , Y _G ) and the standard deviation of the detected data is (σ _X , σ _Y ), the history representative value G is (X _G − 0.2σ _X , Y _G + 0.2σ _Y ). As described above, when the result of the stool condition physical condition analysis based on the stool condition deteriorates beyond a predetermined physical condition level, the gas physical condition analysis result is largely corrected in the direction of poor physical condition as the physical condition level deteriorates (the correction amount is increase).

Further, if it is determined in step S8 that there are two or more “level 3”, the process proceeds to step S10. In step S10, correction is performed to move the history representative value G, which is the center of gravity of the detection data for the past month, by 30% toward the unhealthy (physical condition) side. That is, assuming that the coordinates of the history representative value G are (X _G , Y _G ) and the standard deviation of the detected data is (σ _X , σ _Y ), the history representative value G is (X _G − 0.3σ _X , Y _G + 0.3σ _Y ). As described above, when a strong defecation abnormality appears in the subject, the history representative value G is largely moved toward the poor physical condition, thereby giving a warning to the subject and prompting medical examination. That is, the result of the stool state physical condition analysis is determined as a plurality of levels of physical condition levels such as “level 2”, “level 3”, etc., and the analysis result correcting unit 60b corresponds to the physical condition level determined by the stool state analyzing unit 60a. Then, the correction amount for the result of the gas physical condition analysis is changed to a plurality of stages (for example, 20% of standard deviation, 30%).

  In the biological information measuring system according to the first embodiment described with reference to FIG. 1, the measuring device 6 is incorporated in the toilet seat 4 placed on the flush toilet 2 installed in the toilet room R. However, in the biological information measuring system of the present invention, the measuring device does not necessarily have to be incorporated in the toilet seat.

  FIG. 38A is a diagram illustrating a state in which the subject-side device in the biological information measuring system according to the second embodiment is attached to a flush toilet installed in the toilet room, and FIG. 38B is a measurement of the subject-side device illustrated in FIG. 38A. It is a perspective view which shows an apparatus. In addition, in 2nd Embodiment, compared with 1st Embodiment, only the structure of a test subject side apparatus is different. As shown in FIG. 38A, the biological information measurement system 101 of this embodiment has the same configuration as that of the first embodiment, but only the configuration of the measurement device 106 of the subject side device 110 is different. The measuring device 106 of this embodiment is configured separately from the toilet seat 104.

  As shown in FIG. 38B, the measuring apparatus 106 is attached to the apparatus main body 180, a duct 118a that is attached to the upper surface of the apparatus main body 180 so as to extend in the lateral direction, and whose tip is bent downward, and the apparatus main body 180. And a connected power cord 182. As shown in FIG. 38A, the measuring device 106 is fixed in a state where the end of the duct 118a is located in the bowl by hooking the end of the duct 118a on the side wall of the bowl of the flush toilet 2.

  Similar to the first embodiment, the apparatus main body 180 includes a hydrogen gas sensor, an odorous gas sensor, a carbon dioxide sensor, a humidity sensor, a temperature sensor, an entrance detection sensor, a seating detection sensor, and a defecation / urination detection sensor. And a suction device, a sensor heating heater, and a transceiver. The gas sucked from the duct 118a is deodorized and discharged from a deodorized air outlet provided on the bottom surface of the apparatus main body 180. A hydrogen gas sensor, an odorous gas sensor, a carbon dioxide sensor, a humidity sensor, a temperature sensor, a sensor heating heater, and a fan are provided in the duct 118a. Since the arrangement of the sensors in the duct 118a is the same as in the first embodiment, the description thereof is omitted. With such a configuration, the measuring device 106 of the present embodiment also uses the odorous gas sensor, the hydrogen gas sensor, and the carbon dioxide sensor to adjust the amount of odorous gas, hydrogen gas, and carbon dioxide contained in the defecation gas. The corresponding detection data can be acquired.

  The toilet seat 104 used together with the measurement device 106 of the present embodiment includes a toilet lid opening / closing device, a nozzle driving device, a nozzle cleaning device, a toilet cleaning device, and a toilet sterilization device. It is desirable to use a toilet seat with a washing function that can communicate with By using the measuring device 106 together with such a toilet seat, it is possible to perform various cleaning and sterilization operations when a strange odor gas is detected.

  In the first embodiment, as shown in FIG. 3, in the gas detection device 20, the hydrogen gas sensor 24 is provided on the downstream side of the deodorizing filter 78, but such a configuration is not necessarily required. FIG. 39 is a diagram illustrating a configuration of a gas detection device in the biological information measurement system of the third embodiment. Note that the third embodiment differs from the first embodiment only in the configuration of the gas detection device. As shown in FIG. 39, in the present embodiment, in the gas detection device 120, the arrangement of the hydrogen gas sensor 24 is different from the embodiment shown in FIG. In the present embodiment, the hydrogen gas sensor 24 is provided downstream of the deodorizing filter 78 in the intake passage 18b. According to such a configuration, even when a sensor that reacts not only to hydrogen gas but also to odorous gas is used as the hydrogen gas sensor 24, the influence of odorous gas is detected from data output by the hydrogen gas sensor 24. Can be removed.

  In the first embodiment, the detection value detected by the hydrogen gas sensor 24 is subtracted from the detection value detected by the odorous gas sensor 26 to thereby separate the influence of the hydrogen gas and calculate the detection value of the odorous gas. However, the present invention is not limited to this. For example, the influence of hydrogen gas can be separated by shifting the arrival time of hydrogen gas and odorous gas to the odorous gas sensor 26 as described below. .

  FIG. 40A is a diagram showing a configuration of the gas detection device of the fourth embodiment configured to separate the influence of hydrogen gas by shifting the arrival time of hydrogen gas and odorous gas to the odorous gas sensor. . Note that the fourth embodiment is different from the first embodiment only in the configuration of the gas detection device. As shown to FIG. 40A, in this embodiment, the branch path | route 283b branched from the main path | route 283a of the intake passage 18b in the duct 18a is provided. In the first embodiment, the hydrogen gas sensor and the odorous gas sensor are separately provided. However, in this embodiment, both the hydrogen gas and the odorous gas are detected by a single semiconductor gas sensor.

  Similar to the first embodiment, the intake passage 18b is provided with a filter 72, a deodorizing filter 78 provided downstream of the filter 72, and a suction fan 18c. Branches at The filter 72 is a filter that does not have a deodorizing function, and passes odorous gas and hydrogen, and prevents passage of foreign substances such as urine and cleaning agents. The deodorizing filter 78 is also a catalyst that adsorbs gas components such as odorous gas, as in the first embodiment.

  By the suction fan 18c, the defecation gas in the bowl 2a of the toilet bowl is sucked into the intake passage 18b at a constant flow rate. The defecation gas sucked into the intake passage 18b passes through the filter 72 to remove foreign substances such as urine and cleaning agents, and after the deodorizing filter 78 removes gas components such as odorous gas, Returned to the bowl 2a.

  A flow path switching valve 284, a column 286, a semiconductor gas sensor 288, and a pump 290 are provided in this order from the upstream side to the downstream side in the branch path 283b.

  The flow path switching valve 284 is opened only during a part of the excretion action (for a very short time), and part of the stool gas flowing through the intake passage 18b (a part of the time during the excretion action of the subject). This is a valve for drawing into the branch path 283b. The flow path switching valve 284 is provided in the uppermost stream of the branch path 283b.

  The column 286 is provided on the downstream side of the flow path switching valve 284, and is configured by, for example, filling a thin fiber material or the like in an elongated pipe. The column 286 is a mechanism that causes a difference in gas passage time depending on the molecular size (molecular weight) based on the principle of gas chromatography.

  On the upstream side of the semiconductor gas sensor 288, a sensor heating heater 54 is provided for heating the detection part of the semiconductor gas sensor 288 to a predetermined temperature and removing the off-flavor gas component adhering to the semiconductor gas sensor 288.

  A small amount of defecation gas that has passed through the filter 72 flowing through the intake passage 18b flows into the branch path 283b by the flow path switching valve 284. Then, when the pump 290 is driven, hydrogen and odorous gas contained in the defecation gas pass through the column 286 and reach the semiconductor gas sensor 288 over a different time depending on the molecular weight according to the principle of gas chromatography. That is, hydrogen having a small molecular weight easily passes through the column 286 and reaches the semiconductor gas sensor 288 in a short time, and an odorous gas having a large molecular weight hardly passes through the column 286 and takes a longer time than hydrogen to reach the semiconductor gas sensor 288. To reach. The pump 290 is configured to suck the defecation gas at a constant flow rate.

40B is a diagram showing a detection waveform detected by the semiconductor gas sensor of the gas detection device shown in FIG. 40A. As shown in FIG. 40B, according to the configuration of the gas detection device 220 of this embodiment, the semiconductor gas sensor 288 reacts in a state of being temporally separated from the hydrogen gas and the odorous gas. In particular, excretion is performed in a short time, and defecation gas including hydrogen and odorous gas is released only for a short time. As described above, since the defecation gas is released in a short time, by providing the column 286 upstream of the semiconductor gas sensor 288, the time until the hydrogen gas and the odorous gas reach the semiconductor gas sensor can be shifted. The semiconductor gas sensor 288 can detect the amount of hydrogen gas and the amount of odorous gas. In this case, the inventors also adopted a method of determining the physical condition based on the correlation between healthy gas and odorous gas without measuring the total amount of methyl mercaptan gas correlated with cancer. This is based on the technical knowledge that it is only necessary to measure gas during a specific period. If a reduction sensor is used, it may be inexpensive, but it becomes difficult to separate a large amount of hydrogen contained in the defecation gas. On the other hand, according to the present embodiment, since the measurement is performed only for a small specific period, hydrogen separation is facilitated and practicality can be realized with an extremely inexpensive sensor.
In this embodiment, the arrival time of hydrogen and odorous gas to the semiconductor gas sensor 288 is shifted by the column 286, but it is also possible to shift the arrival time of methane contained in the defecation gas as a matter of course. . Thereby, it is also possible to separate not only hydrogen but also the influence of methane from detection data detected by the semiconductor gas sensor.

Next, with reference to FIGS. 41 and 42, a biological information measuring system according to a fifth embodiment of the present invention will be described.
In the first embodiment described above, the history representative value G on the physical condition display table is corrected to the unhealthy side based on the fecal state (FIGS. 36 and 37). In the present embodiment, when the result of the stool condition physical condition analysis is bad, the point of correcting the plot point based on the latest gas physical condition analysis to the unhealthy side (physical condition side) is different from the first embodiment described above. . Accordingly, only the points of the present embodiment that are different from the first embodiment will be described here, and the description of the same configuration and the like will be omitted.

FIG. 41 is a diagram for explaining correction based on the stool state with respect to the result of the gas physical condition analysis, and FIG. 42 is a flowchart illustrating a correction process based on the stool state with respect to the result of the gas physical condition analysis.
First, in step S21 of FIG. 42, a poor physical condition level based on the fecal state is determined. That is, in the correction in the present embodiment, similarly to the first embodiment, the physical condition level of the subject based on the stool state physical condition analysis is obtained using the correction coefficient table based on the stool state shown in FIGS. Determined. In step S21, in the correction coefficient tables shown in FIGS. 18 to 22, when there is at least one level of poor physical condition based on the stool state of “level 2” or more, the process proceeds to step S22. On the other hand, when all the levels of poor physical condition based on the stool state are less than “level 2”, the correction based on the stool state is not executed, and one process of the flowchart shown in FIG. 42 is terminated.

  Next, in step S22, the flight condition reference correction amount CR is set to a predetermined value. In the present embodiment, the correction amount using the fecal state reference correction amount CR is changed based on the result of the gas physical condition analysis, and the correction amount is increased when the result of the gas physical condition analysis is deteriorated to a predetermined physical condition level or more. The

Further, in step S23, it is determined whether or not the detection data of the odorous gas in the current measurement is “physical condition level 2” or higher on the physical condition display table (FIG. 6). That is, it is determined whether or not the current detection data of odorous gas belongs to “physical disorder level 2”, “disease suspect level 1” or “disease suspect level 2”. If the detected data is "physical condition level 2" or higher, the process proceeds to step S27, and if the detected data is better than "physical condition level 2", the process proceeds to step S24.
Next, in step S24, it is determined whether or not the current detection data of odorous gas is “physical condition level 1” or higher. That is, if the detected data is better than “physical condition level 1”, the process proceeds to step S25, and otherwise, the process proceeds to step S26.

  As shown in FIG. 41, in step S25, the plot points based on the detection data of the odorous gas this time are corrected to the side of poor physical condition by the fecal state reference correction amount CR. That is, in the example shown in FIG. 41, the plot point based on the detection data of the present odorous gas is “1”, and this point approaches the history representative value G by the past history correction (FIG. 7A). The plot point is corrected to “1 ′”. In addition, in the present embodiment, the plot point “1 ′” is corrected to the poor physical condition side (left side in FIG. 41) by a predetermined fecal state reference correction amount CR and moved to the plot point “1 ″”. (In actuality, the plot points “1” and “1 ′” are not displayed). That is, even if the result of the gas physical condition analysis based on the detection data of the odorous gas is good, if the stool condition indicates poor physical condition, the result of the gas physical condition analysis is corrected to the poor physical condition side. Encourage subjects to pay attention to health. Thereby, the display regarding a physical condition analysis can be made highly reliable regarding a test subject's physical condition.

On the other hand, when the detection data of the odorous gas is “physical condition level 1”, the process proceeds from step S24 to step S26.
In step S26, the fecal state reference correction amount CR is increased by 1.2 to correct the plotted points to the poor physical condition side. In the situation where the result of gas physical condition analysis shows poor physical condition, if the physical condition is also poor, the suspicion of true physical condition is further strengthened. The correction amount (stool condition reference correction amount CR) is increased to correct the displayed plot points to the poor physical condition side.

On the other hand, if the detection data of the odorous gas is “physical condition level 2” or higher, the process proceeds from step S23 to step S27.
In step S27, the stool state reference correction amount CR is increased by 1.5 to correct the plotted points to the poor physical condition side. In the situation where the result of the gas physical condition analysis indicates “physical dysfunction level 2” or “suspected illness”, if the stool condition is also poor, the concern about the disease becomes even stronger. The correction amount (stool state reference correction amount CR) based on the stool state with respect to the result is further increased, and the displayed plot points are corrected to the poor physical condition side.
In the example shown in FIG. 41, the plot point based on the detection data of the odorous gas this time is “1 ^* ”, and this point approaches the history representative value G by past history correction (FIG. 7A). The plot point is corrected to “1 ^* ′”. In addition, the plot point “1 ^* ′” is corrected to the unhealthy side (left side in FIG. 41) by the stool state reference correction amount CR multiplied by 1.5 and moved to the plot point “1 ^* ″”. (In fact, the plot points “1 ^* ” and “1 ^* ′” are not displayed).

  As described above, in the biological information measuring system according to the fifth embodiment of the present invention, when the result of the gas physical condition analysis is deteriorated to a predetermined physical condition level or more, the analysis result correcting unit 60b The correction is executed by increasing the correction amount based on the flight status.

  According to the biological information measurement system of the embodiment of the present invention, the analysis result correction unit 60b converts the result of the gas physical condition analysis based on the detection data related to the odorous gas into the stool state over time stored in the stool state storage device 60c. The correction is made based on this (FIGS. 7A, 36, and 41). For this reason, it becomes possible to compensate for the weakness of the gas physical condition analysis that the measurement accuracy is lowered by using the general-purpose odorous gas sensor 26 and the odorous gas does not increase so much in an unaffected subject. The sex can be further improved.

  In addition, according to the biological information measurement system of the present embodiment, the result of the gas physical condition analysis (FIGS. 5 and 6) and the result of the fecal condition physical condition analysis (FIG. 8) are output by the display device 68. Bad lifestyle habits are reflected in the results of the fecal state physical condition analysis, and this is output by the display device 68, so that the subject can be encouraged to improve their life early and effectively reduce the risk of suffering from a major illness. Can do.

  Furthermore, according to the biological information measurement system of the present embodiment, the results of the gas physical condition analysis (FIGS. 5 and 6) and the result of the stool condition physical condition analysis (FIG. 8) recognize the change over time in the results of each physical condition analysis. Since it is displayed in such a way that it can be displayed, it is possible to present the analysis result in an easy-to-understand manner even for subjects who have little knowledge of data analysis. In addition, since changes over time are displayed in a recognizable manner, it is possible to comprehensively present the subject with an increased risk of illness in terms of both defecation gas and stool status, and the subject can reliably take measures to improve physical condition. It becomes possible to do.

  Further, according to the biological information measurement system of the present embodiment, the number of defecation behaviors per day of the subject (FIG. 18), the total amount of defecation during one defecation period of the subject (FIG. 19), and one excretion of the subject The amount of defecation in the action (FIG. 20), the frequency of the subject becoming constipated (FIG. 21), and / or the frequency of the subject becoming loose stool (FIG. 22) is analyzed as the stool state (FIG. 8). It is possible to reliably catch abnormal stool at the time of illness, compensate for the weak points of gas physical condition analysis, and realize physical condition measurement with higher accuracy.

  Furthermore, according to the living body information measurement system of this embodiment, after the fecal state data is accumulated for a predetermined accumulation period or longer, the result of the gas physical condition analysis is corrected (FIG. 36, FIG. 41). Increased risk of major illness is warned by defecation abnormalities, and unnecessary psychological anxiety can be prevented.

  Further, according to the biological information measurement system of the present embodiment, the result of the stool condition analysis (FIG. 8) is output even when the stool condition data is not accumulated, and the correction of the result of the gas condition analysis (FIG. 36). 41) is executed after the fecal state data is accumulated, the subject can recognize the daily health state early while preventing the occurrence of unnecessary psychological anxiety.

Furthermore, according to the living body information measurement system of the present embodiment, since the fecal state is detected, it is sufficient to limit the target of gas physical condition analysis to the detection data at the time of the first excretion (from time t _{5 in} FIG. 10). Physical condition can be measured with high accuracy. In addition, by targeting only the detection data at the time of the first excretion, it becomes possible to display the analysis result of the physical condition at the end of the defecation period by the subject, and the practicality of the biological information measurement system can be improved.

Further, according to the biological information measuring system of the present embodiment, since the fecal state is detected by the defecation / urine detection sensor 38, the fecal gas accompanied by fart (from time t _{5 in} FIG. 10) and feces (in FIG. 10). time t ₆ ~) it is possible to reliably identify, it is possible to reliably select the detection data useful odorous gases in gas physical condition analysis.

  Furthermore, according to the living body information measurement system of the present embodiment, when the gas physical condition analysis result (FIG. 6) deteriorates to a predetermined physical condition level or higher, the correction amount based on the fecal state increases with respect to the gas physical condition analysis result. (FIG. 42), it is possible to notify the subject of the risk of illness with high accuracy. In addition, since the stool state is easier for the subject to recognize than the gas physical condition analysis based on the odorous gas, the subject can easily recognize the increase in morbidity risk, and the subject can be effectively promoted to improve the physical condition.

  Further, according to the biological information measurement system of the present embodiment, when the result of the stool condition physical condition analysis (FIG. 8) deteriorates to a predetermined physical condition level or higher, the correction amount based on the stool condition is set for the result of the gas physical condition analysis. Since it is increased (FIG. 37), it is possible to inform the subject of the risk of morbidity with high accuracy.

  Furthermore, according to the biological information measurement system of this embodiment, the stool state analysis unit 60a determines the result of the stool state physical condition analysis as a plurality of stages of physical condition levels (FIGS. 18 to 22), and the analysis result correction unit 60b According to the physical condition level determined by the state analysis means 60a, the correction amount for the result of the gas physical condition analysis is changed in a plurality of stages (FIGS. 37 and 42), so that the physical condition level can be evaluated and corrected finely. An increase in disease risk can be reliably notified while suppressing an unnecessary psychological burden on the subject.

  Further, according to the biological information measurement system of the present embodiment, the past history correction amount that brings the result of the gas physical condition analysis based on the current measurement closer to the history representative value based on the stool state detected by the defecation / urination detection sensor 38. Since (FIG. 7A) is changed, it is possible to more reliably detect an increase in disease risk over time without greatly complicating the analysis system.

  As mentioned above, although preferable embodiment of this invention was described, a various change can be added to embodiment mentioned above.
