Description

Body information detection system

The present invention relates to a body information detecting system, and more particularly to a body information detecting system based on a defecation gas discharged from a toilet bowl provided in a toilet (i.e., with discharge of stool) The gas discharged from the body) detects the physical condition of the subject.

In recent years, with the development of medical technology, cancer diagnosis has been greatly reduced by the diagnosis of major diseases such as cancer and the development of cancer treatment itself. However, going to the hospital to prevent cancer and make a regular diagnosis is a great burden for the patient. Therefore, the reality is that there are many patients who go to the hospital when they feel that their physical condition is not good, so it is regrettable that there are still many patients suffering from cancer. In addition, a practical device capable of suppressing cancer has not yet been developed, and in fact, it is difficult to achieve cancer prevention.

In view of such a situation, the inventors of the present invention want to manufacture a device that is truly required by the market, can be easily diagnosed for major diseases such as cancer, and can achieve prevention or early treatment of diseases such as cancer without going to the hospital. A strong desire to conduct long-term research.

The applicant has developed the following two devices so far. One is a device for obtaining a defecation amount as a body information index (refer to Patent Document 1), which is disposed on a toilet seat of a toilet (a portion where a toilet seat is seated), and collects a subject to be discharged in the tub during defecation. The defecation gas, based on the concentration of carbon dioxide contained in the defecation gas, obtains the amount of defecation as a body information indicator; the other is a device for inferring the intestinal condition of the subject, which is assembled by the toilet of the flush toilet The deodorizing device on the seat sucks the defecation gas discharged by the examinee together during the defecation, and then the carbon dioxide gas sensor detects the carbon dioxide concentration of the aspirated gas, and based on the detected carbon dioxide concentration, infers the subject's Intestinal condition (refer to Patent Document 2). However, these devices can only infer the current intestinal status of the examiner, and do not achieve the purpose of the inventor, that is, the purpose of simply diagnosing or grasping the risk status of a serious disease such as cancer. Further, there is also known a fart detecting device (Patent Document 3) in which a gas sensor is provided in such a manner as to be able to contact the air in the vicinity of the body excretion portion, and the fart is detected based on the peak value of the gas sensor output. In such a fart detecting device, a hose is taken out from a diaper in a patient's diaper or underwear lying on a bed, and air is sucked by an inhalation pump to collect a patient's fart. In addition, the fart detecting device only distinguishes the fart and the urination based on the half value of the peak value of the sensor output, so that the doctor can confirm whether the patient has fart after the cecal surgery and the time for replacing the diaper, and the device does not achieve the purpose of the inventor. . On the other hand, Japanese Laid-Open Patent Publication No. 2014-160049 (Patent Document 4) discloses a portable colorectal cancer risk detector which can infer the risk of colorectal cancer and has a Detection of the composition of the fart A sensor for methyl mercaptan gas, a calculation portion for calculating a concentration of methyl mercaptan gas obtained by the sensor, and a display portion.

In addition, Japanese Laid-Open Patent Publication No. Hei 9-43182 (Patent Document 5) describes a body detecting device. In this body detecting device, a gas sensor is mounted on the cloth-shaped T-shaped belt, and the gas sensor is placed near the anus to detect the fart discharged from the anus. The signal emitted by the gas sensor is transmitted to the processing device and stored in the memory. The data stored in the memory is compared with the previous data, and the display device issues a warning in the case of an abnormality such as a large difference.

Japanese Laid-Open Patent Publication No. 3525157 (Patent Document 6) discloses a method for detecting an intestinal gas component. In this method of detecting intestinal gas components, a sampling tube is provided in a toilet seat portion of a toilet bowl. After the subject activates the main switch of the device, the suction pump starts to work and draws gas near the anus. The gas index detector continuously detects the concentration of carbon dioxide in the gas to be aspirated, and when a sudden increase in concentration is detected, the control and calculation processing unit recognizes the diffusion of the intestinal gas. After the intestinal gas has spread, another suction pump also starts to work, and a part of the pumped gas is charged into the sample metering tube. The sample is then sent to an analytical column to separate the gas components for ionization. By converting the amount of ionization into an electrical signal, the concentration of the gas component of the test object in the intestinal gas can be detected.

Japanese Laid-Open Patent Publication No. 2014-206945 (Patent Document 7) describes a health information utilization system. In this health information utilization system, personal health information about health management input by the terminal device is stored in a database of a plurality of data centers, and is analyzed by the analysis. The device device reads and analyzes personal health information. The large data generation server device retrieves personal health information according to specific conditions, generates large data, and stores it. The health information utilization system can view the health catalog (content) based on the domain knowledge in the terminal device, store and manage the personal health information in the plurality of data centers, and view the health judgment result of the automatic judgment processing of the personal health information in the terminal device. Or the judgment of the health judgment processed by an expert.

In addition, in the development of a device that can diagnose a serious disease such as cancer, in recent years, it has been gradually known that the disease of colorectal cancer is related to the intestinal gas component contained in the fart or the stool. Specifically, patients with colorectal cancer have more sulfur-containing gas containing sulfur components in the intestinal gas component than healthy people.

The gas component in the intestine is discharged as a fart or defecation gas together with the stool during defecation. Therefore, the inventors have the same idea as the above-mentioned Patent Document 4, as described in the Nihon Keizai Shimbun on January 5, 2015, that is, as long as the methyl mercaptan gas in the fart or the defecation gas discharged during defecation is detected. On the basis of this understanding, continuous colorectal cancer can be found on the basis of specific gases. However, a device which can detect a specific gas such as a methyl mercaptan gas with good precision is very expensive and bulky. In addition, the amount of methyl mercaptan gas contained in the defecation gas is very small, and the amount is relatively small at the stage before the cancer is caused, and the detection is very difficult. Therefore, the inventors at least faced such a problem that, like this, A gas analyzer that is correctly detected is popular as a civilian product that can be installed in a home toilet device, and is unrealistic both in terms of cost and volume.

However, the inventors hope to minimize the number of patients with serious diseases such as cancer. Therefore, with the continuous desire to make a strong desire to make a device that is convenient for general consumers to purchase and to facilitate diagnosis at home, it has finally found a technical solution that can achieve the above desire.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a diagnostic system which is a system which can be easily purchased by a general consumer, and can detect a serious disease such as cancer by using the system for detecting defecation gas at home. Preventing problems before they happen, or can prompt patients to go to the hospital for treatment in mild symptoms, and the system is a diagnostic system that is really demanded by the market and highly practical.

In order to solve the above problems, the present invention is a body information detecting system that detects a physical condition of a subject based on defecation gas discharged from a tub of a flush toilet, and the tub of the flush toilet is provided with a water washing type. The toilet setting space of the toilet is characterized in that the system has: a subject determining means for determining a subject using the flush toilet; and a suction means for sucking the subject to be discharged in the tub of the flush toilet a defecation gas; a gas detecting device having a gas sensor, wherein the gas sensor is a methyl mercaptan gas and a methyl mercaptan gas belonging to an odorous gas containing a sulfur component contained in a gas sucked by the suction device; The other odor gas reacts; the control device controls the suction device and the gas detecting device; and the storage device detects the first detection data detected by the gas detecting device according to the subject determined by the subject determining device Separate storage; data analysis device, detected based on a plurality of defecation behaviors performed during a predetermined period of time, and stored The temporal changes of the plurality of stored first detection materials are analyzed, and the physical condition of the subject is analyzed; and the output device outputs an analysis result of the data analysis device.

In the prior art, there is actually no effective device for confirming whether or not there is a serious disease such as cancer, or for confirming the prevention of a major disease, in addition to the diagnosis of the hospital. In this regard, according to the present invention, the average consumer can easily purchase and detect at home. Moreover, since the defecation gas discharged during defecation is detected, the subject does not need to perform a new detection behavior intentionally, but simply removes the bowel movement as usual, and can prevent the serious disease such as cancer, or go in a state of mild symptoms. The hospital is receiving treatment. Therefore, according to the present invention, There is an excellent effect that a device that is truly required by the market can be realized, and a highly practical diagnostic system can be provided.

Here, before the effect of the present invention is specifically described, the technical concept of the system as a civilian product that can be spread to a general household will be described. The main points here are effective thinking and resolute insights that reflect the characteristics of major illnesses such as cancer and use it.

Specifically, first, a point of the system of the present invention is that the reverse thinking of a serious disease such as cancer is not diagnosed by a device provided by each family. That is, the true idea of the subject as a general consumer is not to know about cancer, but to realize that there is a high risk of cancer in the pre-cancerous stage (hereinafter referred to as non-onset). In order to improve the future life in order not to have cancer. That is, the value of a device required for a general family is such that a healthy person can correctly grasp the risk of cancer and improve his or her condition in order not to have cancer.

Secondly, one of the gist of the system of the present invention is that the system does not need to be a resolute decision to diagnose a particular type of cancer, such as rectal cancer, or to diagnose a device at a high risk for a particular type of cancer. This is because the subject is not uncomfortable with a particular type of cancer such as rectal cancer, but is uncomfortable with any cancer. Therefore, the inventors believe that there is no commercial value in the case where the device cannot diagnose a specific type of cancer, and the related device does not need to have the accuracy of the specific cancer type at all, and it is decided that the system does not require the detection accuracy of a specific cancer type.

Next, one of the main points of the system of the present invention is that the inventor Resolutely think that the diagnostic accuracy of each bowel movement is very low. This is based on the fact that cancer is a disease that has evolved over the years, recognizing that diagnostic opportunities are embedded in the long-term years. Therefore, the inventors have recognized that if the device is positioned to enable a healthy person to reduce the risk of cancer by itself, even if the diagnostic accuracy of one time is low, there is no substantial impact on the diagnosis. The selection based on this effective resolute decision is also an important point of the present invention.

Hereinafter, the effects peculiar to the system of the present invention based on these insights and effective decisive choices will be described.

In the present invention, the defecation gas discharged into the toilet bowl is detected and the physical condition of the subject is analyzed accordingly. Therefore, the subject deliberately performs the detection behavior without undue effort, and the detection can be performed as usual. In addition, the test subject is not burdened without special effort, so that long-term detection can be continued, and information such as changes in health conditions or increased risk of cancer can be reliably grasped.

Further, in the present invention, a sensor for accurately detecting methyl mercaptan gas is not used, and a sensor which reacts widely with an odor gas other than methyl mercaptan gas in the defecation gas is used. In the case of using a sensor that accurately detects methyl mercaptan gas, since the amount of methyl mercaptan gas is related to colorectal cancer, colorectal cancer can be reliably detected, and the amount of methyl mercaptan gas can be surely determined. The risk of cancer increases. However, in this case, it is found that when the risk of cancer increases to a certain extent, and the amount of methyl mercaptan gas does not increase, the risk of cancer is not judged to be increased, which is inconsistent with the purpose of the present invention for preventing cancer.

On the other hand, in the case of using a sensor that reacts widely with odorous gases, it is possible to detect not only an increase in the risk of cancer, but also a poor physical condition. Specifically, first, when the risk of cancer is increased, an odor gas containing a sulfur component such as a methyl mercaptan gas or a hydrogen sulfide is extremely strong. Then, if it is a sensor that reacts widely with odorous gases, an increase in such gas will certainly be detected. In addition, as will be described later, although the amount of gas of the odor gas temporarily increases as the physical condition changes every day, in the case of cancer, the smell of sulfur-containing components such as methyl mercaptan gas and hydrogen sulfide is very high. The state of strong odor gas increase will last for a long time. Therefore, even if a sensor that reacts widely with an odorous gas other than the methyl mercaptan gas in the defecation gas is used, when the amount of gas continues to be high for a long period of time, the possibility of cancer disease can be determined to be high. The risk of cancer is rising and so on. Therefore, at this point, the sensor that reacts widely with the odor gas has the same function as the sensor that targets the detection of the methyl mercaptan gas.

Further, in the present invention, a gas detecting device that reacts not only with the methyl mercaptan gas in the defecation gas but also with the odor gas other than the methyl mercaptan gas is used, and only the amount of the odorous gas in the defecation gas can be known. Therefore, the amount of methyl mercaptan gas cannot be measured, so the state of cancer cannot be correctly determined. However, the inventors discovered that the device detects cancer in healthy people by using a gas detecting device that reacts not only to the methyl mercaptan gas but also the odor gas in the defecation gas other than the methyl mercaptan gas. The state of increased risk and effective function to prevent cancer risk. In detail, in addition to methyl mercaptan gas and methyl mercaptan gas in healthy people The total amount of odorous gas is small. On the other hand, in addition to the cancer, the total amount of the odor gas other than the methyl mercaptan gas and the methyl mercaptan gas is temporarily increased due to deterioration of the intestinal environment. The deterioration of the intestinal environment specifically refers to the deterioration of the intestinal environment caused by excessive constipation, types of food, lack of sleep, overeating, excessive alcoholism, excessive fatigue, and the like. However, any of these reasons can be said to be a bad habit. Although the result of bad habits can lead to cancer, so far, although the risk of cancer is rising, there is no means to identify it. The reality is that most people still think that they don’t want to continue. This bad habit.

In this way, after the behavior of the above-mentioned bad habits occurs, all or any of the odor gases in the defecation gas such as methyl mercaptan, hydrogen sulfide, acetic acid, trimethylamine or ammonia increases. Accordingly, the present invention detects not only the methyl mercaptan gas but also the odor gas in the defecation gas other than the methyl mercaptan gas such as hydrogen sulfide, acetic acid, trimethylamine or ammonia, and based on the detection data of the detecting device. The situation is analyzed. Therefore, the analysis result based on the total amount of the odor gas in the defecation gas can reflect the result of the poor physical condition or poor living habit of the subject, and the analysis result can be used as an improvement for such a high cancer risk. An objective data-based indicator of physical state or lifestyle, that is, it can be used as an effective indicator for maintaining a healthy state and reducing the risk of cancer, and it can be found that the analysis result has the following good effects, that is, for improvement Living habits and the suppression of cancer risk have extremely effective effects.

As such, according to the present invention, since the detection of methyl mercaptan gas and methyl mercaptan The odorous gas other than the gas can be detected by the detection of a state in which the risk of cancer is high or the long-term persistence of the state, and a timely alarm such as cancer is notified to the subject. That is, through reverse thinking, we have found a very suitable insight for the purpose of reducing cancer patients.

Further, according to the present invention, since a sensor that reacts not only with the methyl mercaptan gas but also with an odor gas other than the methyl mercaptan gas, it is possible to manufacture the device at low cost, and the device can be used as a civilian product. Come on. Therefore, the body information detecting system of the present invention can sufficiently satisfy the following needs of the subject, and can be conveniently diagnosed at home, can prevent serious diseases such as cancer, or can promote the patient in a state of mild illness. Go to the hospital for treatment in time.

According to the present invention having such a configuration, the first detection data is detected by a sensor that reacts with an odor gas containing a sulfur component, that is, a methyl mercaptan gas or a odor gas other than the methyl mercaptan gas, and then each The subject stores the first detection data, and analyzes the physical condition of the subject based on the temporal change of the plurality of first detection data among the plurality of defecation behaviors performed in the predetermined period. Therefore, the gas detecting device that uses the sensor that reacts with the odor gas containing the odor component of the sulfur component and the odor gas other than the methyl mercaptan gas detects the detection data, and can use the detection data in time series. By grasping the amount of the odor gas containing the sulfur component in the defecation gas for a long period of time, it is possible to notify the subject of the poor physical condition in the non-onset state before the development of a major disease such as colorectal cancer. Therefore, the body information detecting system can be provided at a cost that is convenient for the general consumer to purchase. Body according to the invention The information detection system can detect defecation gas in the home, so it can prevent serious diseases such as cancer, or prompt patients to go to the hospital for treatment in mild symptoms.

In the present invention, it is preferable that the gas detecting device is configured to react to a healthy gas composed of at least one of hydrogen gas, carbon dioxide gas, or methane gas contained in the gas sucked by the suction device, and output the first 2 detection data; the data analysis device obtains the relationship between the first index and the second index, and analyzes the physical condition of the subject based on the time-dependent change in the plurality of defecation behaviors based on the obtained relationship, wherein the first indicator The second index is related to the healthy gas obtained based on the second detection data, in relation to the odor gas containing the sulfur component obtained from the first detection data in the first defecation behavior.

According to the present invention having such a configuration, the gas detecting device is configured to output second detecting data relating to a healthy gas, and the data analyzing device is based on a first index relating to an odorous gas containing a sulfur component and a health-related gas. The relationship between the two indicators analyzes the physical condition of the subject.

As described above, in the present invention having the above configuration, the physical condition is analyzed based on the first detection data of the odor gas containing the sulfur component and the second detection data of the health gas. This is based on the excellent technical knowledge of the inventors that the accuracy of the analysis is greatly improved by analyzing the odor gas containing sulfur components and the health gas, and the analysis accuracy can be ensured even with simple detection. Achieve the extent to which an intestinal change or an increased risk of cancer can be detected. Specifically, although the amount of odorous gas temporarily changes and decreases due to changes in physical conditions, The amount of the odorous gas is surely continuously increased in the state in which the risk of cancer is increased due to changes in the intestinal environment. Moreover, it is inversely proportional to the increase in the amount of odor gas, and the amount of healthy gas is surely continuously reduced. Therefore, as long as the relationship between the amount of the odor gas and the amount of the healthy gas is utilized, even if the entire defecation gas is not collected, the entire amount of the odor gas is not accurately grasped, and the odor gas containing the sulfur component is used. As well as the analysis of healthy gases, even if such analysis is a simple analysis, it can accurately analyze the physical condition. Therefore, by performing a simple analysis based on the relationship between the odor gas and the healthy gas in the defecation gas collected in a short period of time, it is possible to detect a change in the physical condition and accurately analyze the increase in the risk of cancer. According to the present invention based on such findings, it is possible to make a useful analysis of the physical condition even if a device for performing simple analysis is used.

On the other hand, since the odor gas is extremely small and is analyzed only by the odor gas, the detection system and the detection accuracy are also problematic in consideration of the detection error. In order to fully guarantee the credibility of the test data, a highly sensitive and very expensive odor gas sensor is required, and it is difficult to suppress the rise in the price of the device. According to the present invention having the above configuration, by using the analysis method based on the above-described technical findings discovered by the inventors, an expensive sensor is not used, and on the basis of a simple odor gas sensor, only an inexpensive addition is required. The sensor of the healthy gas can ensure sufficient analysis reliability and achieve a dramatic improvement in the analysis accuracy of the body condition.

In the present invention, it is preferable to further have a subject information storage device that stores the weight, age, sex, or information related to the elapsed time from the previous defecation behavior of the subject, and the data is divided into The analyzer analyzes the physical condition of the subject based on the first detection data, the second detection data, and the subject information stored in the subject information storage device.

According to the present invention having such a configuration, in addition to the first detection data and the second detection data, the physical condition of the subject is analyzed based on the information of the subject, and the physical condition can be detected more accurately. In other words, the inventors of the present invention have found that the amount of the odor gas containing the sulfur component in the defecation gas varies depending on the age and sex of the subject. According to the present invention having the above configuration, since the subject information is comprehensively considered when analyzing the physical condition of the subject, it is possible to eliminate the influence of the difference in the amount of the odorous gas containing the sulfur component due to the individual difference on the analysis. It is possible to detect the physical condition more correctly, and it is possible to avoid an unnecessary psychological burden caused by notifying the subject of the erroneous result.

In the present invention, preferably, the output device displays the plurality of analysis results related to each defecation behavior analyzed by the data analysis device in a time-lapse manner.

According to the present invention having such a configuration, the output device displays the plurality of analysis results related to the respective defecation behaviors analyzed by the data analysis device over time, so that the subject can grasp the temporal change of his or her physical condition and can urge The subject conducts health management activities such as improving living habits.

In the present invention, preferably, the output device displays the plurality of analysis results over time on the body condition display chart, the body condition display chart having the first axis and the second axis, and the first axis indicating that the first detection data is based on the first detection data The first index obtained, the second axis indicates that the second detection data is based on The second indicator obtained.

According to the present invention having such a configuration, a plurality of (multiple times) are displayed on a physical condition display chart having a first axis related to an odorous gas containing a sulfur component and a second axis related to a healthy gas. By analyzing the results, the subject can visually and intuitively grasp the changes in his physical condition and easily judge his own physical condition.

In the present invention, it is preferable that the physical condition display chart is divided into a plurality of levels by region for the good or not of the physical condition, and the plurality of analysis results are marked in a time-lapse manner on the physical condition display chart divided by the region. .

According to the present invention having such a configuration, in view of the health of the physical condition, a plurality of analysis results are marked over time in a physical condition display chart divided into a plurality of levels by area, so that the subject can visually judge Efforts to manage health by the extent to which your physical condition is (what level of health).

In the present invention, it is preferable that the suction device and the gas detecting device are configured to suck the gas and detect the first detection data even before the subject determination device determines the subject to use the toilet. After the first detection data is output, the storage device associates and stores the first detection data with the subject determined by the subject identification device.

In the physical condition detection performed by the body information detecting system of the present invention, the subject can automatically perform physical condition detection only by performing defecation as usual in the toilet. However, if the subject of the defecation is not sure, the storage device cannot accumulate the test data. On the other hand, in every Every time a bowel movement occurs, it is necessary to determine the operation of the subject. Although this operation is simple, it is still annoying to the subject. In addition, sometimes the examinee immediately wants to have a bowel movement after entering the toilet. For these reasons, if the subject does not perform the operation of determining the subject, there is a problem that the body information detecting system is deliberately set but cannot be effectively utilized. According to the present invention having such a configuration as described above, even if the detection of the data is performed before the determination of the subject, it is possible to liberate the subject from the trouble of inputting the information of the subject before the defecation. In addition, when the subject enters the toilet, sits on the toilet seat to start defecation, or after the defecation is completed, the subject can perform the operation of determining the subject, thereby greatly reducing the operational burden when performing the physical condition detection. . Therefore, the excessive operational burden of the subject is not imposed, making it easy to continue the physical condition detection.

In the present invention, preferably, after the gas detecting means detects the first detecting data, when the subject does not input the subject determining means to determine the information of the subject within a predetermined time, the output means This situation informs the subject and urges them to enter.

According to the present invention having such a configuration, when the subject does not input the subject determination information on the subject determination means within the predetermined time, the situation is notified to the subject, and thus the subject can be prevented from forgetting to input the subject. Identify the information to make it easier to continue your physical condition detection.

In the present invention, preferably, the control device is configured to control the cleaning of the toilet, and after the gas detecting device detects the first detection data, When the subject does not input information on the subject determining device to determine the subject, the control device controls to prevent the toilet from being cleaned.

The subject who performs the physical condition detection tends to be unwilling to actively perform the physical condition detection when the detection result is expected to be poor. In this case, it is expected that the subject will intentionally not perform the operation of determining the subject after defecation, thereby avoiding the situation of the physical condition detection. According to the present invention having such a configuration as described above, when the subject does not input the subject to determine the information, the toilet is not cleaned, so that the subject can be forced to input the subject to confirm the information semi-mandatoryly, and semi-mandatoryly Understand the results of physical condition testing. Therefore, while it is possible to surely continue the detection of the physical condition, it is also possible to strongly urge the subject to manage the physical condition and prevent the occurrence of a major illness due to continued poor physical condition.

In the present invention, preferably, the output device corrects the analysis result of the data analysis device, and marks the corrected analysis result on the physical condition display chart.

According to the present invention having such a configuration, the analysis result is corrected and marked on the physical condition display chart, so that it is possible to prevent a large error caused by the detection data and a temporary physical condition from being unsatisfactory, causing a large occurrence of the displayed physical condition. fluctuation.

In the present invention, it is preferable that the output device corrects and displays the analysis result marked on the physical condition display chart to the side where the physical condition is good when the most recent analysis result changes to the side where the physical condition is not good.

According to the present invention of this configuration, the physical condition display chart The analysis result and the physical condition marked on the body are corrected to the side where the physical condition is good. Therefore, it is possible to prevent a large error caused by the detection data and a temporary physical condition from being deteriorated, and the displayed physical condition is rapidly deteriorated. The tester brings an excessive psychological burden.

In the present invention, preferably, when the analysis result indicating that the physical condition is not good continues to occur for a predetermined number of times or more, the output device reduces the amount of correction for the analysis result and displays it.

According to the present invention having such a configuration, when the analysis result indicating that the physical condition is not good continues to occur for a predetermined number of times or more, the correction amount for the analysis result is reduced, and therefore, the physical condition is poor for the persistent poor physical condition. As a result, the subject can be informed of the result of poor physical condition before the deterioration, and urged to strengthen health management or go to the hospital for treatment.

In the present invention, preferably, the output device displays a message related to the health management of the subject based on the analysis result of the data analysis device.

According to the present invention having such a configuration, it is possible to display a message related to the health management of the subject, and therefore the subject can take an appropriate action based on the displayed physical condition of the subject, and start to improve his or her physical condition as soon as possible.

In the present invention, preferably, the data analysis device calculates the reliability of the detected data based on the first detection data and the second detection data, and the output device marks the analysis result corrected based on the data reliability in the physical condition. Display on the chart.

In the use of sensors that react widely to odorous gases In the present invention, the first test data may be subjected to an odorous gas component such as sweat or urine adhered to the body of the test subject, or a perfume attached to the toilet or the toilet, or an odor gas, a fragrance, or an alcohol bactericide remaining in the toilet. Impact. In particular, the higher the odor of the perfume or fragrance, the less unacceptable the detection accuracy may be when the body or toilet is unsanitary. In addition, when the person uses the system (using a toilet) immediately after defecation, the odor component such as the defecation gas and the attached odor of the person who used the toilet may remain in the toilet, and even the toilet at this time It is not an unsanitary space and it will have an impact on testing. On the other hand, according to the present invention having the above configuration, the analysis result is corrected based on the reliability, so that it is possible to prevent the marked point displayed on the physical condition display chart from fluctuating greatly due to the analysis result with low reliability. The tester brings an unnecessary psychological burden.

In the present invention, preferably, when the reliability of the data calculated by the data analysis device is low, the output device displays the analysis result marked on the physical condition display chart as compared with the case where the reliability of the data is high. The correction amount closer to the side of the past marked point is increased.

According to the present invention having such a configuration, when the reliability of the data is low, the correction amount of the analysis result marked on the physical condition display chart is increased, and the analysis result is brought closer to the side of the past marked point, so that it is possible to prevent The low-confidence data makes the mark point change to the side of the poor physical condition, and brings unnecessary psychological burden to the test subject.

In the present invention, it is preferable that the data analysis device calculates the reliability value of the data to be smaller when the detection noise included in the first detection data and the second detection data is larger.

According to the present invention having such a configuration, the larger the detection noise included in the detection data, the lower the reliability value of the data is calculated, thereby preventing the low accuracy detected in an environment where the detection of a residual gas or the like is large. The detection data causes the marked points to change greatly to the side where the physical condition is not good, and brings unnecessary psychological burden to the subject.

In the present invention, it is preferable that the defecation discharged at the initial stage of the detection is compared with the weight of the first detection data and the second detection data of the defecation gas discharged at the later stage of the detection. The weight of the first test data and the second test data of the gas is significant.

So far, it is generally believed that since the methyl mercaptan gas is produced by cancer cells, during the defecation period, a large amount of methyl mercaptan gas is discharged at a timing corresponding to the position of the cancer cells, but the inventors found that At the beginning of the defecation period, a large amount of gas is discharged. This can be considered as a characteristic that the gas is more likely to be discharged than in the stool during defecation, or because the generated gas accumulates near the anus over time. In the present invention based on such findings, the weight of the detection data of the defecation gas discharged at the initial stage of detection is significantly greater than the weight given to the later detection data, so that more accurate detection can be performed. In addition, by detecting the defecation gas discharged at the beginning, it is possible to notify the subject of the analysis result immediately after the end of the defecation behavior or immediately after the end of the defecation behavior, and it is possible to notify the subject of the detection result of the physical condition without waiting for the subject to wait excessively. Detector.

In the present invention, preferably, in the defecation behavior of the subject once, the data analysis device only uses the detection of the first discharge of the defecation gas. The first test data and the second test data are analyzed.

According to the present invention having such a configuration, only the detection data of the defecation gas discharged first is used for analysis, and it is possible to perform useful physical condition detection with high reliability with a small amount of data.

Further, when the subject who performs the physical condition detection is expected to have a poor detection result, there is a tendency that the test result is unwilling to actively understand the detection result. In this case, when the detection result of the physical condition is output after the defecation behavior of the subject is completed, it is foreseen that the subject leaves the toilet without waiting for the output of the physical condition detection result after the defecation behavior ends. According to the present invention having such a configuration as described above, only the detection data of the first discharge of the defecation gas is used for analysis, so that the body condition detection result can be outputted while sitting on the toilet before the subject ends the defecation behavior. It is true that the subject who is unwilling to actively understand the test result is informed of the result of the physical condition test.

In the present invention, it is preferable that the body condition display chart has a first axis indicating the first index and the second axis indicating the second index, and the first region indicating the degree of the physical condition is also set on the body condition display chart. And a second region indicating that the physical condition is in a bad state compared to the first region, and at least a part of the boundary line between the first region and the second region is drawn as the value of the first index increases as the value of the second index increases. In addition, the second region indicating that the physical condition is in a bad state is distributed on the side of the value of the first index of the boundary line.

In the existing health state detecting device using the defecation gas, the body shape is detected only by detecting carbon dioxide as a healthy gas. Moreover, the detection result of the health condition is determined only by the amount of carbon dioxide. However, in the unoccupied state immediately before a serious illness, there is a case where the physical condition has begun to deteriorate even if a large amount of carbon dioxide is generated. According to the present invention having the above configuration, even if the values on the second axis indicating the second index are the same, the health state is differently evaluated based on the value on the first axis indicating the first index, and a more precise physical condition can be performed. Detection.

In the present invention, preferably, the gas detecting device has both a sensor for detecting hydrogen gas and a sensor for detecting carbon dioxide gas.

According to the present invention having such a configuration, since the sensor for detecting hydrogen gas and the sensor for detecting carbon dioxide gas are provided, it is possible to perform evaluation based on two kinds of gases indicating a good state of the physical condition, so that the physical condition can be detected more accurately. .

In the present invention, it is preferable that the gas detecting device is configured to detect the vaporized short-chain fatty acid contained in the defecation gas sucked by the suction device, and the data analysis device is based on the detection data of the odor gas. The first index, the second index based on the detection data of the healthy gas, and the third index based on the detection data of the short-chain fatty acid are analyzed as indicators of the physical condition of the subject.

According to the present invention having such a configuration, since the physical condition is analyzed based on the first, second, and third indexes, it is possible to widely detect the physical condition in a range from a suspected disease state to a state in which the immunity to the disease is high. Can indeed detect the physical condition.

In the present invention, it is preferable that the data analysis device is configured to analyze whether the physical condition of the subject is good based on the first and second indicators, and The analysis result is output to the output device, and when the value of the third index is large, the data analysis device is compared based on the analysis result of the first and second indicators, compared with the case where the value of the third index is small. The analysis results that are corrected to the side with good physical condition are output to the output device.

There are many error factors in the first and second indicators that originate from the state of defecation and detection of environmental noise. On the other hand, the inventors of the present invention found that short-chain fatty acids are not produced in a state where the intestinal state is not good and the probiotics are not much. According to the present invention having such a configuration as described above, when the third index based on the short-chain fatty acid is large, the analysis result based on the first and second indexes can be corrected to the side where the physical condition is good, thereby avoiding the 1. The detection error of the second indicator brings an unnecessary psychological burden to the subject.

In the present invention, it is preferable that the gas detecting device is configured to detect acetic acid or propionic acid as a short-chain fatty acid, and the data analysis device analyzes the tendency of the detected data based on acetic acid or propionic acid over time. Physical conditions.

The inventors of the present invention have found that among the short-chain fatty acids produced by probiotics in a good intestinal environment, acetic acid and propionic acid are highly volatile, and volatilized acetic acid is compared with other short-chain fatty acids. And propionic acid is more contained in the defecation gas. According to the present invention having such a structure as described above, the physical condition of the subject is analyzed by detecting acetic acid or propionic acid belonging to the short-chain fatty acid, and therefore, it is easier to detect than the analysis based on other short-chain fatty acids. , analysis, and the ability to use inexpensive sensors for inspection. In addition, sensors that detect short-chain fatty acids are not necessary It is a sensor that reacts only with acetic acid or propionic acid, and can use a sensor capable of detecting both, or a sensor capable of detecting acetic acid or propionic acid and other short-chain fatty acids other than acetic acid or propionic acid. .

In the present invention, it is preferable to further have a squat determination device capable of detecting whether or not the subject is suffering from a sputum, and when the squat determination device determines that the subject is suffering from a sputum, the shortness detected by the defecation behavior is not used. The detection data of chain fatty acids are used to analyze the physical condition or to reduce the weight of the test data.

The inventors of the present invention have found that when the intestinal environment is good, the deodorant gas contains a short-chain fatty acid. However, the inventors of the present invention have also found that a large amount of short-chain fatty acids are contained in the defecation gas in the case where the subject suffers from sputum. According to the present invention having such a configuration as described above, in the case where it is judged that the subject is suffering from sputum, the detection of the short-chain fatty acid detected in the defecation behavior is not used to analyze the physical condition, or the weight of the detected data is lowered, thereby enabling It is possible to suppress the risk of a bad physical condition being judged to be good due to squatting.

In the present invention, preferably, the structure is a data analysis device that analyzes the current health status of the subject, and analyzes the resistance of the subject to the disease based on the detection data of the short-chain fatty acid.

There are many probiotics in the intestines, and short-chain fatty acids are produced by probiotics, so that the pH in the intestines is low, and the pathogenic bacteria that deteriorate the intestinal environment are not suitable for survival. In this way, if the intestinal environment is a condition in which the pathogenic bacteria are not suitable for survival, the state of the intestine will not deteriorate, and it is said that the state in the intestine is less susceptible than the state in which only the amount of healthy gas is increased. The state of illness. According to the present invention having such a configuration as described above, it is possible to analyze the immunity against the disease, that is, the immunity, against the subject based on the current state of health of the subject and the short-chain fatty acid.

According to the body information detecting system of the present invention, it is possible to perform physical condition detection in daily life without causing unnecessary psychological burden to the subject, and to inform the person that the physical condition is not good in the non-infected state.

Hereinafter, a first embodiment of the body information detecting system of the present invention will be described in detail with reference to the drawings.

First, FIG. 1 is a view showing a state in which the body information detecting system according to the first embodiment of the present invention is attached to a flush toilet provided in a toilet. Fig. 2 is a block diagram showing the configuration of a body information detecting system according to the present embodiment. Fig. 3 is a view showing the configuration of a gas detecting device included in the body information detecting system according to the embodiment.

As shown in Fig. 1, the body information detecting system 1 has a subject side device 10 composed of a detecting device 6 and a remote controller 8 provided on a wall surface of the toilet R, the detecting The device 6 is mounted inside the toilet seat 4, and the toilet seat 4 is mounted on the flush toilet 2 provided in the toilet R. Further, as shown in Fig. 2, the body information detecting system 1 includes a server 12, a subject terminal 14 such as a smart phone to which a dedicated software is installed, and a medical institution terminal 16 installed in a medical institution such as a hospital. The device realizes a part of the functions of the body information detecting system 1 by exchanging data with the subject side device 10. In the server 12 and the medical institution terminal 16, detection data sent from the plurality of detector side devices 10 is accumulated, and these data are subjected to data analysis.

The body information detecting system 1 of the present embodiment performs a body including a judgment on cancer based on an odor gas containing a sulfur component in the defecation gas discharged by the subject during defecation, particularly a methyl mercaptan (CH ₃ SH) gas. Condition analysis. Further, in the body information detecting system 1 of the present embodiment, in addition to the odor gas, other healthy gases are detected, and the accuracy of the physical condition analysis is improved based on the relationship. Healthy gases are gases derived from intestinal fermentation, and the higher the intestinal health, the greater the amount of gas, specifically carbon dioxide, hydrogen, methane, short-chain fatty acids and other gases. In the present embodiment, the detected healthy gas is carbon dioxide gas and hydrogen gas, and since these two gases are easily detected and the amount thereof is large, the detection reliability of a high health index can be maintained. Here, each subject side device 10 is configured to display an analysis result immediately after defecation or defecation in the subject. On the other hand, in the server 12, the detection results from a plurality of subjects are accumulated, and by performing comparison with other subjects, further detailed analysis can be performed. In this way, the body information detecting system 1 of the present embodiment performs a simple analysis in the subject-side device 10 installed in the restroom R, and performs further detailed analysis in the server 12.

Here, the principle of the body condition detection of the body information detecting system 1 of the present embodiment will be described.

There are reports in the literature that cancers of the digestive organs series, especially those suffering from colorectal cancer, are discharged at the same time as the odor gas of sulfur components such as methyl mercaptan or hydrogen sulfide from the affected part. The digestive organs refer to the esophagus, stomach, duodenum, small intestine, large intestine, liver, pancreas, gallbladder, etc. The large intestine can also be classified into appendix, cecum, rectum and colon, but these four parts are collectively referred to as the large intestine. Cancer is a disease that develops with little change every day. After the development of cancer, the amount of odorous gases containing sulfur components, especially methyl mercaptan, will increase. In other words, when the amount of the odor gas containing the sulfur component increases, it can be determined that the cancer is developing. Moreover, in recent years, there has been a view that is called “non-incidence”, that is, the idea of improving the physical condition in time to prevent disease before the illness is poor. Pan-propagation. Therefore, it is necessary to detect the condition before the development of cancer, especially in the case of colorectal cancer, and to improve the physical condition in time.

Here, in the defecation gas discharged during defecation, in addition to hydrogen sulfide and methyl mercaptan, it also contains nitrogen, oxygen, argon, water vapor, carbon dioxide, hydrogen, methane, acetic acid, trimethylamine, ammonia, propionic acid, and Methane disulfide, methyl trisulfide, and the like. Here, in order to judge cancer, it is necessary to detect an odor gas containing a sulfur component, particularly methyl mercaptan. The content of propionic acid, dimethyl disulfide, and trisulfide methyl contained in the defecation gas is very small compared with methyl mercaptan. Therefore, it is not a problem to judge the analysis of the physical condition such as cancer, and it can be ignored. However, other gas components are not traced to the extent that they can be ignored. In order to correctly judge cancer, it is of course considered to use a sensor capable of detecting only an odorous gas containing a sulfur component. However, a sensor capable of detecting only an odorous gas containing a sulfur component is bulky and very expensive, and is difficult to use as a device for home use.

In this regard, after intensive research by the inventors, the result is that a gas sensor that can detect an odorous gas containing other odorous gas components is used instead of detecting only methyl mercaptan. Cheap home appliances can be built. Specifically, the inventors have decided to use a general-purpose semiconductor gas sensor or a solid electrolyte type sensor that reacts not only with a sulfur-containing gas containing a sulfur component but also with other odorous gases.

In a state in which the risk of cancer is increased, an odorous gas having a very strong odor containing a sulfur component such as a methyl mercaptan gas increases. Also, as long as it is a pair such as a semiconductor gas sensor or a solid electrolyte type sensor The sensor that emits a wide range of odorous gases will definitely detect this increase in gas. However, as will be described later, a sensor that responds to odorous gases such as a semiconductor gas sensor or a solid electrolyte type sensor can also detect a body due to bad living habits. Odorous gases such as hydrogen sulfide, methyl mercaptan, acetic acid, trimethylamine, and ammonia are added in poor condition. However, cancer is a disease that has been developed for a long period of time. In the case of cancer, the state in which the odorous gas containing a sulfur component such as methyl mercaptan gas or hydrogen sulfide is extremely strong will continue to persist for a long period of time. Therefore, even if a general-purpose semiconductor gas sensor or a solid electrolyte type sensor that reacts not only with a sulfur-containing gas containing a sulfur component but also with other odorous gases, when the gas amount continues to be high for a long period of time, It is also possible to determine the possibility of cancer and the risk of cancer is increasing.

Further, the semiconductor gas sensor or the solid electrolyte type sensor using the redox reaction not only detects the methyl mercaptan gas, but also detects acetic acid, trimethylamine, ammonia, and the like which are also odor gases in the defecation gas. However, the inventors have found that the amount of odorous gases such as hydrogen sulfide, methyl mercaptan, acetic acid, trimethylamine, and ammonia has the following tendency, and is increased when the physical condition caused by bad habits is deteriorated. , reduced when the body is in good condition. Specifically, the total amount of the odor gas other than the methyl mercaptan gas and the methyl mercaptan gas of a healthy person is small. On the other hand, the total amount of the odor gas other than the methyl mercaptan gas and the methyl mercaptan gas temporarily increases due to the deterioration of the intestinal environment due to the following reasons: excessive constipation, food type, lack of sleep, Overeating, excessive alcoholism, overwork, etc.

In addition, the acetic acid in the defecation gas tends to increase not only when the physical condition caused by diarrhea or the like is deteriorated, but also when the physical condition is good. That is, this does not necessarily coincide with the tendency of the amount of gas of other odorous gases such as methyl mercaptan gas that changes with the above-described physical condition. However, the amount of acetic acid contained in the defecation gas is very small compared to the methyl mercaptan gas, and the amount of acetic acid gas increases even when the body is in good condition, and the amount of increase is also smaller than the reduction of other odorous gases. very small. Further, when the physical condition caused by diarrhea or the like is deteriorated, the amount of increase in acetic acid is extremely large as compared with the increase in the case where the physical condition is good. Therefore, the amount of the odor gas contained in the defecation gas generally increases when the physical condition is deteriorated due to bad living habits, and tends to decrease when the physical condition is good. In addition, as a result of the deterioration of the intestinal environment caused by the bad living habits, the amount of gas of the odorous gas contained in the defecation gas becomes a timely improvement of the body before the cancer occurs. A suitable indicator of the condition.

In the present embodiment, the physical condition is analyzed based on the detection data of a semiconductor gas sensor or a solid electrolyte type sensor, and the semiconductor gas sensor or the solid electrolyte type sensor is not only for the methyl mercaptan gas but also The odor gas contained in the defecation gas other than the methyl mercaptan gas such as hydrogen sulfide, acetic acid, trimethylamine or ammonia is reacted. Therefore, an analysis can be obtained that reflects the consequences of poor physical condition or poor living habits. This analysis can be used as an indicator based on objective data to improve the physical condition or lifestyle of patients with increased risk of cancer. .

In addition, there are not only odorous gases in the defecation gas, but also H ₂ and methane. In the case where a semiconductor gas sensor or a solid electrolyte type sensor is used for the gas sensor, these sensors are also used for H. ₂ reacts with methane. Further, in the case where a detection device using a semiconductor gas sensor or a solid electrolyte type sensor is provided in each household, there is a concern that these sensors also react to a fragrance or a fragrance.

In this regard, as described later, the inventors have determined the following solutions, namely, using a hydrogen gas sensor, a methane sensor, and an analytical column, from the detection of a semiconductor gas sensor or a solid electrolyte type sensor. The method of separating the effects of hydrogen and methane, and the effect of the fragrance or perfume as a method of detecting noise removal by detecting defecation behavior. Therefore, by separating the influence of hydrogen gas and methane from the detection data of the semiconductor gas sensor or the solid electrolyte type sensor, and removing the influence of the fragrance or the perfume, it is possible to estimate only the odor gas in the defecation gas. The amount itself.

Further, the amount of gas of methyl mercaptan gas or other odorous gas contained in the defecation gas is very small compared with H ₂ and methane. Therefore, even if a semiconductor gas sensor or a solid electrolyte type sensor is used, there is a fear that the amount of the mixed gas of these odorous gases cannot be accurately detected.

In this regard, the inventors focused on the fact that the intestinal environment of a healthy person is acidic, but after becoming a cancer patient, an odorous gas containing a sulfur component is generated, and the amount of gas is increased. In addition, the intestinal environment is also alkaline, and the amount of bifidobacteria is also reduced. The amount of healthy gas in the fermented components such as CO ₂ , H ₂ , and fatty acids increases with the amount of odorous gas. It is indeed and continuously reduced in inverse proportion.

Therefore, the inventors have made the following assumptions, although the detection accuracy of each test is not necessarily high, by monitoring the amount of gas of an odorous gas such as methyl mercaptan and the health gas components such as CO ₂ and H ₂ every day during defecation. The correlation between the amount of gas may detect the development of cancer in development.

Here, when the inventors examined the amount of the gas of the healthy gas and the odor gas contained in the defecation gas of a healthy person, a 6- to 7-year-old healthy person, an early cancer patient, and a developmental cancer patient, The result as shown in Fig. 44 was obtained. In other words, the amount of the healthy gas contained in the defecation gas of the healthy person is small, and the amount of the odorous gas is small. In contrast, the amount of the healthy gas contained in the defecation gas of the cancer patient is small, and the amount of the odor gas is large. . Moreover, compared with early cancer, the amount of gas of healthy gas contained in the defecation gas of a developing cancer patient is reduced. Further, when the amount of the healthy gas and the amount of the odorous gas are in an intermediate amount between the cancer patient and the healthy person, it can be considered as a gray region, that is, an uninfected state. Therefore, based on the above findings, the inventors thought that it is possible to detect the amount of healthy gas and the amount of gas of the odor gas of the subject, and based on the correlation between them, the accuracy of judging the state of health can be improved.

Further, in FIGS. 45 to 51, there are shown data comparing the amounts of various gases contained in the defecation gas of healthy people and colorectal cancer patients (including developmental cancer and early cancer).

Figure 45 is a graph comparing the amount of hydrogen sulfide gas contained in the defecation gas of healthy people and colorectal cancer patients. The following are the various other gases contained in the defecation gas of healthy people and colorectal cancer patients, respectively, as compared in the respective figures. A graph of the quantity, wherein the 46th is a methyl mercaptan gas, the 47th is hydrogen, the 48th is carbon dioxide gas, the 49th is propionic acid gas, and the 50th is acetic acid Gas, Figure 51 is a butyric acid gas. In each of the figures, in the test data for each gas amount in (a), the healthy person is represented by a circular mark, and the colorectal cancer patient is represented by a triangular mark. In addition, in (b), the average value of each test data is represented by a straight line chart, and the standard deviation of the test data is indicated by a line segment.

From the test data in Fig. 45 to Fig. 51, it can be seen that, in the amount of various gases contained in the defecation gas, although healthy people and colorectal cancer patients are irregular (dispersed), they are used as an odorous gas. The hydrogen sulfide gas and the methyl mercaptan gas can be seen in a large number of data showing that the colorectal cancer patient has a large amount of such gas, while the healthy person has almost no data showing a large amount of such gas. On the other hand, for hydrogen gas, carbon dioxide gas, many materials showing a large amount of such gas can be seen in healthy people, and data showing a large amount of such gas is hardly seen in colorectal cancer patients. In this way, the amount of gas of the odor gas which is contained in the defecation gas and which shows the risk of colorectal cancer is large, and there are many patients with colorectal cancer, and the number of healthy people is small. In contrast, the amount of hydrogen and carbon dioxide gas as a healthy gas is There are many healthy people and few patients with colorectal cancer. As such, the magnitude relationship between the amount of odorous gas and the amount of healthy gas in the healthy person and the colorectal cancer patient is reversed. These test data show that it is difficult to sufficiently detect the physical condition of the subject by the gas detection amount of the odor gas and the healthy gas once, but the relationship between the odor gas and the healthy gas is continuously performed for a predetermined period of time. When a plurality of tests are performed, the physical condition of the subject can be reliably detected.

In addition, when the inventors detected the defecation gas, it was found that in one bowel movement, the excretion behavior was performed several times (one fart or one excretion large) In the case of the behavior, the amount of defecation gas discharged with the first excretion behavior is large and there are many odor gases. Therefore, in the present embodiment, in order to accurately detect a small amount of odor gas, the state of health of the subject is analyzed based on the first defecation gas. Therefore, it is possible to reduce the influence of stool and fart which may be discharged by the first excretion behavior when detecting the amount of defecation gas discharged from the excretion behavior after the second time (including the second time).

Further, as will be described later, a hydrogen gas sensor and an odor gas sensor can be integrated into a single sensor.

The temperature sensor 32 detects the temperature of the detecting portion of the odor gas sensor 26 or the like. In addition, the humidity sensor 30 detects the humidity of the gas sucked from the tub body 2a. The sensitivity of these sensors varies slightly due to the temperature of the detector. In addition, changes in humidity due to urination and the like also affect the sensitivity of the sensor. In the present embodiment, since the amount of the odorous gas is extremely small, in order to stably detect such a trace amount of gas with high precision, the CPU 22a on the toilet side controls the temperature and humidity detected by the sensors 30 and 32, as described later.

In addition, it is also possible to detect whether it is a state of defecation such as diarrhea. Alternatively, the defecation urination detecting sensor 38 may be constituted by a CCD or a water level sensor that detects the displacement of the water level.

The toilet seat cover opening and closing device 40 is a device that opens and closes the toilet seat cover as the case may be based on a detection signal of the entrance detecting sensor 34 or the like.

The nozzle driving device 42 is a device for cleaning the buttocks, that is, a device for cleaning the buttocks of the subject after defecation. The nozzle driving device 42 is configured to drive the nozzle to clean the water-washing toilet 2.

The nozzle cleaning device 44 is a device for cleaning the nozzle of the nozzle driving device 42. In the present embodiment, the structure is such that hypochlorous acid is generated from tap water, and the nozzle driving device 42 is sprayed with the generated hypochlorous acid. tube.

The toilet washing device 46 is a device that puts water or tap water stored in a washing water tank (not shown) into the toilet and cleans the inside of the tub 2a of the flush toilet 2. The toilet washing device 46 is usually made of The examiner operates the remote controller 8 to operate the inside of the tub 2a, but as will be described later, it can be automatically operated by the control device 22 as occasion demands.

In the toilet sterilizing device 48, for example, sterilizing water such as hypochlorous acid is produced from tap water, and the sterilized water to be sprayed is used to spray the tub 2a of the flush toilet 2, and the sterilizing operation of the tub 2a is performed.

The fragrance sprayer 50 is a device that sprays the toilet R with a predetermined fragrance. This is to prevent the subject from arbitrarily using the fragrance to spray the toilet R, and to make the odor component in the spray become a detected external noise detecting device. Since the fragrance sprayer 50 is provided, a predetermined fragrance which does not affect the detection can be used, and sprayed in a predetermined amount at a predetermined time as the case may be, so that the body information detecting system 1 can recognize the fragrance spray. Therefore, the external detection noise for the detection of the physical condition can be reduced, and the analysis result can be stabilized, so that the fragrance sprayer 50 can function as an output stabilization device.

The suction device 18 has a fan that sucks the gas in the tub body 2a of the flush toilet 2, and the sucked gas flows through the detecting portion of the odor gas sensor 26 and the like, and is deodorized by the deodorizing screening program. The detailed structure of the suction device 18 will be described later.

The deodorizing air supplier 52 is a device that deodorizes the air sucked by the suction device 18 and then discharges it into the tub body 2a.

The sensor heater 54 is a device that heats and activates the detecting portion of the odor gas sensor 26 or the like. By keeping the detecting portion of each sensor at a predetermined temperature, it is possible to accurately detect a predetermined gas component.

The pipe cleaner 58 is a secondary chlorine obtained by, for example, electrolyzing tap water. A device for cleaning the inside of the pipe 18a installed on the suction device 18 by acid.

Further, in the present embodiment shown in Fig. 1, the suction device 18, the deodorizing air supplier 52, and the duct cleaner 58 are integrally formed as a deodorizing device. That is, the gas in the tub 2a is sucked into the inside of the duct 18a by the suction device 18, and the sucked gas is deodorized by the deodorizing screening program 78 (Fig. 3), and is deodorized. The gas is again discharged into the tub body 2a. Therefore, it is possible to suppress the inflow of gas which can react with the odor gas sensor 26 from the outside into the tub body 2a, and during the defecation of the subject, the gas component in the tub body 2a can be suppressed, which is discharged by the subject. It changes for reasons other than defecation. Therefore, the deodorizing device and the deodorizing air supplier 52 having the deodorizing screening program 78 can function as an output stabilizing device. Alternatively, as a modification, the present invention may be configured as follows, and a gas supply device for detection (not shown) is provided, and the gas supply device for detection causes gas that does not react with each gas sensor to flow into the tub 2a, and A gas equal to the amount of gas to be sucked by the suction device 18 flows into the barrel 2a. In this case, the gas supply device for detection (not shown) can function as an output stabilization device that stabilizes the analysis result.

Next, as shown in FIG. 2, the remote controller 8 is provided with a data analysis device 60, and the data analysis device 60 is connected to the subject determination device 62, the input device 64, the transceiver 66, the display device 68, and the speaker 70. . In the present embodiment, the transceiver 66, the display device 68, and the speaker 70 function as an output device that outputs the analysis result of the material analysis device 60. In addition, the data analysis device 60 is composed of a CPU, a storage device, and These devices are configured to operate, and the like, and a database is built in the storage device.

In the present embodiment, the input device 64 and the display device 68 are configured by a touch panel, and can receive various kinds of input information such as the subject's identification information such as the name of the subject, and can display various kinds of information such as the detection result of the physical condition.

The speaker 70 can output various alarms and messages issued by the body information detecting system 1.

In the subject determination device 62, the subject identification information such as the name of the subject is registered in advance. When the subject uses the body information detecting system 1, the name of the registered subject is displayed on the touch screen, and the subject selects his or her name.

Further, the transceiver 66 on the remote controller 8 side is connected to the server 12 via the Internet, and can communicate. The subject terminal 14 may be, for example, a device such as a smart phone, a tablet, or a computer that can display received data.

The server 12 has a library of defecation gas. In the defecation gas database, in association with the subject identification information of each subject using the body information detecting system 1, the detection data including the amount of the odor gas and the amount of the gas of the healthy gas in each defecation behavior is recorded and Credibility data, which is stored with the detection time. Further, in the server 12, a diagnostic chart is recorded, and a data analysis circuit is additionally provided.

Further, the server 12 is connected to the medical institution terminal 16 installed in a hospital or a health care institution via the Internet. The medical facility terminal 16 can be powered, for example The brain and the like are configured to view the data recorded by the database of the server 12 by the medical institution terminal 16.

Next, the configuration of the gas detecting device 20 provided in the toilet seat 4 will be described with reference to Fig. 3.

First, in the body information detecting system 1 of the present embodiment, a semiconductor gas sensor is used as the gas sensor in the gas detecting device 20 in order to detect the odor gas and the hydrogen gas. Further, in order to detect carbon dioxide, a solid electrolyte type sensor is used in the gas detecting device 20.

The detecting portion of the semiconductor gas sensor is composed of an oxidized metal film containing tin oxide. When the detection portion is heated to a temperature of several hundred degrees, when the heated detection portion is exposed to the reducing gas, an oxidation-reduction reaction occurs between the oxygen adsorbed on the surface and the reducing gas. The change in the resistance value of the detecting portion caused by the redox reaction is electrically detected, and the semiconductor gas sensor can thereby detect the reducing gas. The reducing gas detectable by the semiconductor gas sensor includes hydrogen gas and odor gas. Further, in the present embodiment, the sensor for detecting the odor gas and the sensor for detecting the hydrogen gas use the semiconductor gas sensor at the same time, but the detection portion used to strengthen the odor gas sensor is stinky. The reaction of the taste gas is also adjusted to adjust the composition of the detection unit in order to enhance the reaction of the detection unit used in the hydrogen sensor to hydrogen gas.

As described above, in the present embodiment, the "semiconductor gas sensor" is used as the "odor gas sensor", but as described above, the "odor gas sensor" uses a general feeling. a detector that reacts to the methyl mercaptan gas as a test object, His odorous gas reacts widely. Further, as described later, a solid electrolyte type sensor may be used as the "odor gas sensor", but similarly to the semiconductor gas sensor, the solid electrolyte type sensor may also use a p-methyl mercaptan gas. A general sensor that reacts widely with other odorous gases. In other words, the sensor that reacts only with the methyl mercaptan gas is very difficult to manufacture, and even if it can be manufactured, it becomes an extremely large and expensive sensor. Even if the medical device required for advanced clinical examination can be implemented with such a large and expensive sensor, the body information detecting system that is manufactured as a civilian product at such a cost that can be sold out is not used. possible. In the body information detecting system of the present embodiment, a simple and versatile gas sensor that reacts with other odorous gases in addition to reacting with the methyl mercaptan gas as the detecting object is used as a stinky The gas sensor is used to realize a body information detection system as a civilian product. As described above, the gas sensor used in the present embodiment reacts to the odor gas other than the methyl mercaptan gas and the methyl mercaptan gas, but in the present specification, it is called "smelly" for the sake of convenience. Flavor gas sensor". Typical examples of the odor gas to be reacted by the "odor gas sensor" used in the present embodiment include a methyl mercaptan gas, a hydrogen sulfide gas, an ammonia gas, and an alcohol-based gas.

In addition, the "odor gas sensor" used in the body information detecting system 1 of the present embodiment is a sensor that reacts with an odor gas other than the detecting object methyl mercaptan gas, but by Various methods to be described later, even if such a sensor is used, it is possible to use a civilian product. The necessary precision is checked for accuracy. Specifically, the following methods may be mentioned: a method of preparing a detection environment in a space having various odorous gases such as a toilet; and estimating a defecation behavior of the subject by a detection signal of the gas sensor, and extracting the defecation gas A method of data processing of data; even if a test data having a large error is obtained, there is no method for causing an unnecessary psychological burden to the test subject. Various methods will be described in detail later.

Further, in the present embodiment, a case has been described in which a semiconductor gas sensor is used as a sensor for detecting an odor gas and hydrogen gas. However, it is also possible to replace the semiconductor gas sensor with a solid electrolyte type sensor. The solid electrolyte type sensor is, for example, a sensor that first heats a solid electrolyte such as stabilized zirconia and then detects the gas based on the amount of ions passing through the solid electrolyte. The gas that the solid electrolyte type sensor can detect includes hydrogen gas and odor gas. Further, in the present embodiment, a sensor for detecting carbon dioxide is a solid electrolyte type sensor. However, the carbon dioxide sensor is not limited to this, and an infrared method or the like can also be used. In addition, the sensor that detects carbon dioxide may also be omitted.

As shown in Fig. 3, in the present embodiment, the gas detecting device 20 is provided inside the suction device 18.

The suction device 18 is composed of a duct 18a that faces downward, an intake passage 18b that faces in a substantially horizontal direction, and a suction fan 18c that is provided on the downstream side of the intake passage 18b. Further, a duct cleaner 58 and a humidity adjusting device 59 are provided inside the intake passage 18b.

The gas detecting device 20 is provided by a screening process provided inside the intake passage 18b. The equation 72 includes an odor gas sensor 26, a hydrogen gas sensor 24, and a carbon dioxide sensor 28. As shown in the figure, the screening program 72 is disposed to traverse the intake passage 18b, and an odor gas sensor 26, a hydrogen gas sensor 24, and a carbon dioxide sensor 28 are arranged side by side on the downstream side of the screening program 72. .

Further, a deodorizing screening program 78 is provided on the downstream side of the odor gas sensor 26, whereby the deodorizing screening program 78 deodorizes the sucked gas, so that the suction device 18 also functions as a deodorizing device. The function.

Further, a humidity adjusting device 59 is provided on the downstream side of the deodorizing screening program 78. The humidity adjusting device 59 is provided with a moisture absorbent, and when it is necessary to reduce the humidity in the tub 2a, the flow path is switched so that the air passing through the deodorizing screening program 78 passes through the encapsulated moisture absorbent from the tub body. Remove water from the air in the loop in 2a. Therefore, the proper humidity in the tub body 2a can be maintained, so that the detection sensitivity of each gas sensor is maintained to a certain extent. Therefore, the humidity adjusting device 59 can suppress the change in the humidity in the tub 2a and function as an output stabilization device.

The suction fan 18c suctions the odor gas containing the odor gas from the tub 2a of the flush toilet 2 at a constant speed, and then returns it to the tub body 2a after deodorization. In order to prevent the droplets such as urination from entering, the suction port of the deodorizing duct 18a is opened in the tub body 2a in a downward direction. Since the molecular weights of methyl mercaptan gas and hydrogen gas are small, they rise immediately after defecation. On the other hand, in the present embodiment, the suction fan 18c sucks from the inlet of the duct 18a opened in the tub body 2a, so that the discharged odor gas and hydrogen gas can be reliably introduced into the gas detecting device 20. like this, The suction device 18 starts to operate before the subject begins to defecate, and a certain flow rate of gas is brought into contact with the respective gas sensors during the defecation of the subject. Therefore, a stable detection value can be obtained. Therefore, the suction device 18 and the control device 22 that controls the operation thereof can function as an output stabilization device.

The screening program 72 is a screening program that does not have a deodorizing function, and is configured to pass odorous gas, hydrogen gas, and carbon dioxide to prevent the passage of foreign matter such as urine or a cleaning agent. As such a screening program 72, a member that mechanically collects foreign matter, such as a fine mesh member, without using a chemical reaction can be used. Therefore, it is possible to prevent the odor gas sensor 26, the hydrogen gas sensor 24, and the carbon dioxide sensor 28 from being contaminated by urinary stones or the like.

Further, with respect to the respective sensors, sensor heaters 54 are provided on the upstream side of each sensor and on the downstream side of the screening program 72, respectively. As described above, the odor gas sensor 26 and the hydrogen gas sensor 24, which are semiconductor gas sensors, can detect hydrogen gas and odor gas in a state where the detecting portion is heated to a predetermined temperature. The sensor heater 54 is provided to heat the odor gas sensor 26 and the detecting portion of the hydrogen gas sensor 24. In addition, the solid electrolyte of the carbon dioxide sensor 28 also needs to be heated to a predetermined temperature, and thus the sensor heater 54 is provided. These sensor heaters 54 function to remove the odor gas component adhering to the sensor by heating, thereby functioning as an odor removing device. Further, in the case where a solid electrolyte type sensor is used as the odor gas sensor or the hydrogen gas sensor, a sensor heater in which the heating detecting portion is provided is also required.

And, the sensor heater 54 also functions as a sensor The function of the deposit removal device. Although the gas passing through the screening program 72 is freed of foreign matter, the sucked gas contains various odorous gas components. Such an odorous gas component adheres to each of the sensors, and can cause detection of noise when detecting a trace amount of odorous gas. In this regard, the sensor detecting portion is heated by the sensor heater 54, and the odor gas adhering to the sensor can be heated and removed without providing a new device. In addition, before the start of the defecation behavior of the subject, the control device 22 controls the sensor heater 54 to bring the respective sensors to a certain temperature. That is, the control device 22 controls the sensor heater 54 in such a manner that the temperature of each sensor is suppressed by the contact of each sensor with the airflow. Therefore, during the defecation of the subject, the sensitivity of each sensor can be managed at a predetermined value, and the detection error of each sensor can be suppressed. Therefore, the control device 22 and the sensor heater 54 can stabilize the analysis result of the output and function as an output stabilization device.

Further, the deodorizing screening program 78 is a catalyst screening program for adsorbing an odorous gas such as an odor gas. The air obtained by removing the gas such as the odor gas by the deodorizing screening program 78 is sent back to the tub body 2a. At this time, if the gas returned to the tub body 2a further contains an odorous gas, the odorous gas flowing into the tub body 2a is again sucked by the duct 18a, and the presence is again detected by the odor gas sensor 26. Possible. Therefore, in the present embodiment, by providing the deodorizing screening program 78 on the downstream side of the odor gas sensor 26, it is possible to surely remove odorous components such as odorous gases from the gas returned to the tub body 2a. .

In addition, after the subject is seated on the toilet seat 4, The upper part of the tub body 2a is closed in underwear or the like. When a negative pressure is formed in the tub body 2a, the odor gas component attached to the body or clothing of the subject is sucked into the tub body 2a. In the body information detecting system 1 of the present embodiment, the sensitivity of the odor gas sensor 26 is set to be extremely high in order to detect only a trace amount of odor gas contained in the defecation gas. In other words, even the odor gas component attached to the body or clothing of the subject will be an external detection noise. On the other hand, in the present embodiment, since the deodorized gas is returned to the tub body 2a, a negative pressure is not formed in the tub body 2a, and the odor gas adhering to the body or clothing of the subject can be prevented. The ingredients are sucked into the tub 2a.

Here, the semiconductor gas sensor employed in the odor gas sensor 26 can detect not only the odor gas but also the hydrogen gas. Therefore, it is necessary to separate the influence of the hydrogen gas from the detection data detected by the semiconductor gas sensor. In the present embodiment, a hydrogen separation mechanism for separating the influence of such hydrogen gas is provided, and the hydrogen separation mechanism removes hydrogen gas from the detected value of the odor gas detected by the semiconductor gas sensor in the gas detecting device 20. The hydrogen gas detection value detected by the sensor 24 is used to separate the influence of the hydrogen gas, and the value obtained by subtracting the hydrogen gas detection value is output as the odor gas detection value. Here, a configuration portion including such a hydrogen gas separation mechanism, a semiconductor gas sensor, and a hydrogen gas sensor, and outputting a detection value based on the amount of the odor gas and the amount of the hydrogen gas is referred to as a detection value output means. Further, the arithmetic processing of subtracting the detected value of the hydrogen gas detected by the hydrogen gas sensor 24 from the detected value of the odor gas detected by the semiconductor gas sensor may be performed in the data. The analysis device 60 or the like performs. Further, in the present embodiment, the hydrogen separation device for separating the influence of the hydrogen gas from the detection data detected by the semiconductor gas sensor has been described. However, a methane sensor capable of detecting methane may be provided. The effect of methane separation is separated from the detection data detected by the semiconductor gas sensor. As the methane sensor, a semiconductor gas sensor in which the material of the detecting portion has been adjusted to a material that strongly reacts with methane may be used.

In addition, many people do not have methane-producing bacteria that can form methane in their intestines, or even if they are present, the amount of methane contained in many people's defecation gases is very small. Therefore, in the present embodiment, the hydrogen gas sensor 24 and the carbon dioxide sensor 28 are provided as the health gas sensor. However, there are occasional people who have a lot of methane-producing bacteria in the intestines. In a defecation gas of a person with a large number of intestinal methane-producing bacteria, the amount of methane is large, and the amount of hydrogen is small. Therefore, in the case where only the hydrogen gas sensor 24 and the carbon dioxide sensor 28 are provided, the defecation gas of a person having a large amount of intestinal methane-producing bacteria is judged to be a small amount of healthy gas, and this is undesirable. of. In the present embodiment, the hydrogen gas sensor 24 and the carbon dioxide sensor 28 are provided as health gas sensors for the purpose of being used by more people. However, in order to be suitable for people with a large amount of methane gas, a methane gas sensation may be used. The detector replaces the hydrogen gas sensor 24. Further, it is preferable to provide a methane gas sensor in addition to the hydrogen gas sensor 24 and the carbon dioxide sensor 28, thereby being able to cope with any subject.

As explained above, the defecation gas contains a large amount of hydrogen. Gas, and the semiconductor gas sensor can detect not only odor gas but also hydrogen gas. In this regard, by subtracting the amount of hydrogen gas detected by the hydrogen gas sensor 24 from the amount of gas detected by the odor gas sensor 26 for the semiconductor gas sensor, the influence of the hydrogen gas can be separated. Therefore, the amount of gas of the odorous gas can be accurately detected.

Further, the molecular weight of the hydrogen gas contained in the defecation gas is very small compared with the air, and the hydrogen gas easily runs out of the barrel 2a. On the other hand, in the present embodiment, since the decoy gas is sucked by the suction fan 18c of the suction device 18, the defecation gas containing the hydrogen gas can be reliably collected.

In addition, if the sucked defecation gas is returned to the barrel 2a as it is, the detection accuracy of the odor gas sensor 26 is lowered. On the other hand, in the present embodiment, the sucked defecation gas is deodorized by the deodorizing screening program 78 and sent back to the tub body 2a, so that the amount of odor gas and the amount of hydrogen gas can be accurately detected. Further, the deodorizing screening program 78 as described above is required to be disposed downstream of each sensor, but if the deodorizing screening program 78 is disposed downstream of each sensor, the sensor is directly contaminated by foreign matter. possibility. On the other hand, in the present embodiment, since the screening program 72 that does not have the deodorizing function is provided on the upstream side of the sensor, it is possible to reduce the contamination of the sensor by the foreign matter without affecting the detection of the odorous component.

In addition, the gas in the suction tub 2a causes the pressure in the tub 2a to drop, and there is a fear that the odor gas component adhering to the body or clothing of the subject flows into the tub body 2a. On the other hand, in the present embodiment, the air from which the odorous component has been removed by deodorization is returned to the tub body 2a, so that it is possible to prevent the adhesion of the body or clothing of the subject. The taste gas component flows into the tub body 2a, and can be correctly detected.

However, it is not necessary to return the air from which the odorous component has been removed by deodorization to the tub body 2a. In the case where the air which has been deodorized and the odor-removing component is returned to the tub body 2a is not used, the odor gas component adhering to the body or clothing of the subject flows into the tub body. Worry in 2a. However, as described with reference to Fig. 9 which will be described later, when the residual gas standard value is set, the standard value of the residual gas is set based on the influence of the odor gas component attached to the body or clothing of the subject. . Therefore, the amount of gas can be estimated without returning the air from which the odorous component has been removed by deodorization to the tub body 2a.

Next, a flow of the physical condition detection by the body information detecting system 1 according to the first embodiment of the present invention will be described with reference to FIG. 4 and FIG.

Fig. 4 is a flow chart for explaining the physical condition detection, the upper part shows the steps of the body condition detection, and the lower part shows an example of the screen displayed on the display unit of the remote controller in each step. Fig. 5 is a view showing an example of a screen displayed on a display device of a remote controller.

The body information detecting system 1 according to the present embodiment is a system that analyzes a physical condition including cancer, and is based on an odor gas and a healthy gas contained in the defecation gas discharged by the subject during defecation. The relationship between them. Here, it is preferable that the apparatus on each subject side displays the analysis result in a short period of time during the defecation or during the end of the defecation period to the exit of the toilet. But in a short time Performing the analysis will reduce the accuracy of the analysis. Further, it is difficult to suck the defecation gas discharged from all the subjects by the suction device 18, and at the same time, it is feared that the external detection noise is formed by the following conditions, which has an influence and reduces the detection accuracy, that is, the toilet or the toilet The environment is very unsanitary or the fragrance is very strong. Therefore, in the subject-side device, when the physical condition including the presence or absence of the disease is transmitted to the subject, the menstrual result detected based on the long-term and multiple defecation behaviors is taken into consideration in consideration of the psychological burden of the subject. It does not focus on the absolute amount of odor gas that is highly correlated with cancer, but focuses on the change in the physical condition of the subject, that is, the change in the condition of the intestine. Further, in consideration of the detection error in each of the defecation behaviors, in the present embodiment, in order to notify the subject that the physical condition of the subject changes greatly without causing a detection result based on the one-time defecation behavior, the notification to the subject is also notified. Work hard. This approach takes advantage of the long-term development of cancer as a result of the dramatic increase in the strong odorous gases associated with cancer in a short period of time that is not closely related to cancer, but rather the result of poor habits or Detecting the effects of noise, so showing a large change in physical condition will bring unnecessary psychological burden to the subject.

In view of the above, in the present embodiment, first, the subject-side device 10 performs the detection result of the first defecation gas in the first defecation behavior, that is, the defecation gas discharged from the first excretion behavior. A simple analysis of the health status and an analysis of the health status. In this regard, in the server 12, based on the total amount of gas discharged in one bowel movement behavior, compared with other subjects, it is possible to perform more detailed analysis. Here, in the body information detecting system 1 of the present embodiment, the subject-side device 10 installed in the toilet R performs simple analysis, and further detailed analysis is performed in the server 12.

As shown in FIG. 4, in the detection of the primary defecation behavior by the body information detecting system 1 of the present embodiment, the steps performed are: a pre-detection environment preparation step S1, a detection start preparation step S2, and a detection standard value setting step. S3. Detection step S4, diagnosis step S5, communication step S6, and post-detection environment preparation step S7.

The pre-detection environment conditioning step S1 is a step performed before the subject enters the toilet R. Further, whether or not the subject has entered the toilet R is detected by the entrance detecting sensor 34 (Fig. 2).

In the pre-detection environment conditioning step S1, the toilet seat side control device 22 controls the sensor heater 54, the suction device 18, and the toilet seat cover opening and closing device 40 to change to the detection standby mode. In the detection standby mode, the sensor heater 54 is controlled based on the temperature detected by the temperature sensor 32 so that the temperature of the detecting portion of the odor gas sensor 26 is lower than the temperature at which the detection is performed. (eg 200 ° C). In the detection standby mode, the suction device 18 is controlled in a state in which the amount of suction air is the smallest. The toilet seat cover opening and closing device 40 is controlled to be in a state of closing the toilet seat cover in the detection standby mode.

Further, in the pre-detection environment conditioning step S1, the detecting portion of the odor gas sensor 26, although the sensor heater 54 is in the detection standby mode, the detecting portion of the odor gas sensor 26 is at a ratio It is most suitable for low temperature conditions, but it is also possible to detect the concentration of odorous gases. A stool or the like is attached to the water-washing toilet 2, and the odor gas is emitted from the barrel 2a. In the case of a source, the gas concentration detected by the odor gas sensor 26 may be above a predetermined value. Therefore, in the pre-detection environment conditioning step S1, when the gas concentration detected by the odor gas sensor 26 is equal to or greater than a predetermined value, the control device 22 cleans the toilet. Specifically, the control device 22 causes the nozzle of the nozzle driving device 42 to discharge the washing water to clean the tub 2a, and the toilet washing device 46 discharges the water stored in the washing water tank to clean the inside of the tub 2a, or to remove the toilet. The bacteria device 48 generates sterilizing water such as hypochlorous acid water from tap water, and sprays the tub body 2a with sterilizing water to sterilize the tub body 2a.

Further, when the gas concentration detected by the odor gas sensor 26 is equal to or greater than a predetermined value, the control device 22 may control the operation of the suction device 18 to discharge the gas in the tub 2a to lower the gas concentration. Since the gas sucked by the suction device 18 is deodorized by the deodorizing screening program 78, the suction device 18 and the deodorizing screening program 78 also have the function of the deodorizing device. In addition, when the toilet seat cover is opened, the gas is sucked by the suction device 18, and not only the inside of the tub 2a but also the inside of the toilet R can be deodorized. Therefore, the suction device 18 and the deodorizing screen can also be used. The check program 78 functions as a toilet deodorizing device. Preferably, when the suction device 18 and the deodorizing screening program 78 function as a toilet deodorizing device, the suction device 18 is pumped up as compared with when the detecting person performs the defecation period. The amount of gas sucked.

Alternatively, a ventilating device (not shown) may be provided in the toilet R, and the control device 22 controls the operation of the ventilating device to reduce the gas concentration. By reducing the concentration of the odor gas remaining in the tub body 2a in this manner, it is possible to reduce the influence of the residual gas detection noise caused by the residual gas. therefore, In the pre-test environment conditioning step S1, the nozzle driving device 42, the toilet washing device 46 or the toilet sterilization device 48 is used to clean or sterilize the tub body 2a, and the row in the tub body 2a or the restroom R Gas and deodorization can function as a detection noise countermeasure device for reducing the influence of detection noise of residual gas, and as a residual gas removal device for reducing the concentration of residual odor gas. In addition, the detection noise countermeasure device that is operated when the subject does not enter the toilet and the time other than the defecation period of the examinee functions as the first detection noise countermeasure device, and also functions as a residual gas removal device.

Further, in the pre-detection environment preparation step S1, when the gas concentration detected by the odor gas sensor 26 is not lower than a predetermined value even if the above-described toilet cleaning is performed, the control device 22 is transmitted by the transceiver 56. The command signal for cleaning the warning. When the transceiver 66 on the remote controller 8 receives the command signal for the cleaning warning, the display device 68 or the speaker 70 notifies the subject to clean the toilet.

Further, in the pre-detection environment conditioning step S1, the control device 22 periodically cleans the suction environment. Specifically, the control device 22 drives the duct cleaner 58 to spray cleaning water into the duct 18a of the suction device 18 to clean the duct 18a. Further, the hydrogen gas sensor 24, the odor gas sensor 26, and the carbon dioxide sensor 28 are heated to a high temperature to burn off the odor gas component to which the surfaces of the sensors 24, 26, 28 are attached.

Next, after the entrance detecting sensor 34 detects that the subject enters the toilet, the control device 22 transmits the start of the detection start preparation step S2 to the transceiver 66 on the remote controller 8 side by the transceiver 56. The signal is considered and synchronized with the remote controller 8 side to perform the detection start preparation step S2.

In the detection start preparation step S2, first, the subject determination means 62 provided in the remote controller 8 determines the subject. Specifically, in the body information detecting system 1, the occupant of the house in which the system is installed is registered, and the registered occupant is displayed as a candidate of the candidate (candidate). In other words, as shown in FIG. 5, buttons of "subject A", "subject B", "subject C", and the like as candidates are displayed on the upper portion of the display device 68 of the remote controller 8, The subject is determined by pressing a button corresponding to himself by the subject entering the toilet R. Further, the data analysis device 60 provided in the remote controller 8 refers to the storage device and acquires past detection data and physical condition display charts of the personal identification information accepted by the subject identification device 62, wherein the physical condition display chart is used as standard data. That is, the standard of analysis.

Further, in the detection start preparation step S2, as shown in Fig. 5, as shown in Fig. 5, the data analysis device 60 displays, in the second stage of the display device, for example, "Is the last time I had a bowel movement in another place?" "So, the question about whether the toilet was defecate last time with this device, and the options for answering this are "Yes (this morning)", "Yes (Yesterday afternoon)", "Yes (Yesterday)", "The day before yesterday" Before", "No". The subject's defecation history information is input to the input device 64 of the data analysis device 60 by the respondent's response. The temporal decompression history information about the last defecation behavior from the subject is stored in the storage device (the subject information storage device) provided in the remote controller 8, and the subject information storage device stores the event information. First registered about the weight of the subject, year Age, gender, etc. In addition, the defecation history information is sent to the server 12 and recorded in the database of the server 12.

Further, in the detection start preparation step S2, the toilet-side control device 22 controls the sensor heater 54, the suction device 18, and the toilet seat cover opening and closing device 40 to be in the detection mode. In the detection mode, based on the temperature detected by the temperature sensor 32, the sensor heater 54 is controlled to control the temperature of the detecting portion of the odor gas sensor 26 to a temperature suitable for detection (350 ° C). Further, in the detection mode, the air volume of the suction device 18 is controlled to rise so that the defecation gas does not leak from the tub body 2a to the outside, and such air volume is controlled to a certain extent without fluctuation. Further, in the detection mode, the toilet seat cover opening and closing device 40 is controlled to open the toilet seat cover.

Further, in the detection start preparation step S2, when the odor gas sensor 26 detects that the odor gas concentration is high, the control device 22 controls the toilet sterilizing device 48 to sterilize the tub body 2a.

Further, in the detection start preparation step S2, in a case where the value detected by the humidity sensor 30 is not suitable for the odor gas sensor 26 to detect the defecation gas, the control device 22 sends a signal to the humidity adjustment device 59 to control the barrel. The humidity in the body 2a reaches a suitable value (a value suitable for detection).

Further, in the detection start preparation step, if the toilet seat 4 is cleaned by a cleaning cloth or spray using an alcohol-based bactericide, the ethanol reacts with the odor gas sensor 26 to rapidly increase the gas concentration. When the odor gas sensor 26 detects that the gas concentration suddenly increases, the data analysis device 60 displays a warning on the display device 68.

Further, the data analysis device 60 stores the detected value of the odor gas sensor 26 as an environmental standard value, and the environmental standard value herein is a detection noise level based on the detection of the defecation gas. Based on this environmental standard value, the data analysis device 60 determines whether it is an environment in which detection is possible. Then, when the data analysis device 60 determines that the current environment is still detecting the detection noise level, or is not detectable, the display device 68 is detected as shown in the lower part of FIG. The user is prompted to "Check for preparation! Please wait" and urge the display of the standby defecation.

In the detection start preparation step S2, before the subject is seated, the detection noise of the odor gas remaining before the subject enters the toilet is determined, or the odor component attached to the subject is attached. The subject detects a noise level detected by noise, etc., and stores it as a source/detection noise detection standard value, and determines whether or not the detection is possible.

Next, after the seat detecting sensor 36 detects that the subject is seated, the control device 22 transmits a signal to the data analyzing device 60 to start the detection standard value setting step S3 by the transceiver 56, and analyzes the data with the data. The device 60 synchronously performs the detection standard value setting step S3. In addition, when the seating detection sensor 36 repeats a predetermined number of times between the detection of the detected person and the inability to detect the detected subject, since the subject is affected by the cleaning of the toilet seat, in this case, It is preferable to return to S1.

In the detection standard value setting step S3, the data analysis device 60 performs the attachment based on the detection value of the odor gas sensor 26, resulting in attachment to the subject. The detection of noise of the odor is judged, that is, the detected odor of the detected odor is detected by the detector. In other words, when the detected value detected by the odor gas sensor 26 is sufficiently lowered and is unstable, it is determined that there is a possibility that sterilization is performed using the ethanol-based sterilizing agent, and the lower portion of FIG. 4 is continuously displayed. The "Detection preparation! Please wait" is displayed. Alternatively, when the detection noise level from the subject is equal to or greater than a predetermined value, the data analysis device 60 sends a signal to the nozzle driving device 42 as the partial cleaning device to clean the buttocks of the subject. Alternatively, the data analysis device 60 is notified by the display device 68 to the subject to urge the hip to be cleaned. In this way, the data analysis device 60 controls the operation of cleaning the buttocks and urges the subject to perform the work of cleaning the buttocks, and the notification of the detection of the noise to the subject is greatly notified by the first detection noise. In response to the different measures of the device, it can function as a second detection noise countermeasure device that reduces the detection of noise by the subject. In addition, the first detection noise countermeasure device operates when the subject does not enter the toilet R, whereas the second detection noise countermeasure device operates when the subject enters the toilet R. On the other hand, when the detected value detected by the odor gas sensor 26 is sufficiently lowered, the display is eliminated. Further, in the case where the detected value detected by the odor gas sensor 26 is not sufficiently lowered even after a predetermined time elapses, the data analysis device 60 stops the detection of the physical condition, and indicates this on the display device 68. Display, inform the subject. In this way, the data analysis device 60 determines that the gas component in the tub 2a is unsuitable for detection before the defecation period of the subject, and stops the detection of the physical condition of the subject, so that it can function as an output stabilization device. can.

Further, in the detection standard value setting step S3, the data analysis device 60 sets a standard value for estimating the gas amount based on the gas concentration detected by the odor gas sensor 26 as will be described later in detail.

Next, as will be described later in detail, when the detected value of the odor gas sensor 26 is greatly increased based on the standard value, the data analysis device 60 determines that the subject is performing the excretion behavior. In this manner, the data analysis device 60 performs the detection step S4 from the determination that the subject has started the excretion behavior until the seat detection sensor 36 detects that the subject is off seat.

In the detecting step S4, the hydrogen gas sensor 24, the odor gas sensor 26, the carbon dioxide sensor 28, the humidity sensor 30, the temperature sensor 32, the entrance detecting sensor 34, the seating detection sensing The detection data detected by the defecation urination detecting sensor 38 is stored in the storage device by the control device 22 in accordance with the subject determined by each of the subject determining devices 62. After the end of the detecting step S4, the control device 22 transmits the detected values stored in the storage device to the data analyzing device 60 via the transceiver 56 after the detecting step S4 is completed. Further, in the present embodiment, the information is transmitted from the control device 22 to the data analysis device 60 after the detection step S4 is completed. However, the present invention is not limited thereto, and the information may be transmitted instantaneously while being detected.

Further, even if the subject does not input the subject judgment information to the subject determination device 62, the control device 22 starts the detection of the defecation gas. The data detected before the information is input, after which the subject enters the information of the subject in a defecation behavior, An association with the entered subject information is established and stored in the storage device. This is a practical method of combining the characteristics of the defecation behavior as follows, that is, in the case of a critical time of defecation, various inputs are not performed first, and then input is stabilized. Further, when the detected time has elapsed and the subject has not input the subject information, the display device 68 and the speaker 70 output a message urging the subject to input, and notify the subject. Thereby, it is possible to prevent the subject from forgetting the input.

At the same time, similarly to the detection standard value setting step S3, the data analysis device 60 determines whether or not detection is possible. When the data analysis device 60 determines that the detection is possible, the data analysis device 60 displays the "detector: Tosuta Taro (detector identification information) to the subject as shown in the lower portion of Fig. 4 by the display device 68. "Mr.", "Detect OK! In-progress detection" means that the user has been prompted to detect the subject.

Next, after the seat detecting sensor 36 detects that the subject has left the seat, the control device 22 transmits a signal to the data analyzing device 60 to start the diagnosis step S5 by the transceiver 56. The data analysis device 60 starts the diagnosis step S5 after receiving this signal.

The data analysis device 60 first calculates the detection reliability based on the detection values detected by the respective sensors as will be described later in detail.

On the other hand, in the case where the subject does not input the subject judgment information until the subject is seated, the control device 22 prohibits the washing of the flush toilet 2. That is, even if the subject does not input the judgment information of the subject, even if the subject operates the cleaning button of the remote controller 8 (not shown), the control The device 22 also does not discharge the washing water of the flush toilet 2, but displays information urging its input. Therefore, the subject can be strongly urged to input the subject to determine the information.

Further, as will be described later in detail, the data analysis device 60 estimates the amount of gas of the odor gas and the hydrogen gas (health type).

Further, in the diagnosis step S5, the data analysis device 60 performs a diagnosis result calculation for analyzing the physical condition of the subject, which is based on the multiple detections stored in the storage device detected when the bowel movement is performed multiple times during the predetermined time. Time-dependent changes in data. This calculation is performed and the time-lapse diagnosis is also performed based on the stored values. Then, based on this time-based diagnosis, the suggested content is selected. As shown in the third paragraph of Fig. 5, the material analysis device 60 displays the selected suggestion content as a message regarding health management on the display device 68. In the example shown in Fig. 5, as a result of the diagnosis, it is indicated that the current physical condition of the subject belongs to "poor physical condition", and as a suggestion, "the intestinal environment is deteriorating, please pay attention to healthy living."

Further, below the diagnosis result, the amount of gas of a healthy gas such as hydrogen gas or carbon dioxide gas in this test, and the amount of gas such as an odor gas having poor physical condition are also displayed. In addition, the results of the past 4 tests are displayed side by side below the recommendations. Further, after the subject presses the "detailed screen" button on the display screen, a graph indicating the change in the physical condition of the subject in the past month is displayed. This display will be described later. As described above, among the analysis results displayed on the display device 68 of the remote controller 8, only the physical condition, the suggestion, and the physical condition change (history of the detected data) do not contain the information displayed on the medical institution terminal 16. Notification of cancer judgment results. Further, the analysis result may be notified to the subject terminal 14 of the test.

Further, as shown in the lowermost portion of Fig. 5, the reliability of the current detection data is displayed on the lower portion of the display device 68. In the example shown in Fig. 5, "4" having a relatively high degree of reliability is displayed. In addition, in the case where the reliability is low, below the reliability indication, the reason for the low reliability and the suggestion for improvement are displayed. For example, in the case where the residual gas originating from the residual gas in the barrel body detects noise, or the detected subject from the subject detects that the noise is large, the reliability is lowered, and the detection result is notified to the subject. Subject to detection of noise. Therefore, the reliability expressed by the display device 68 indicates that the function of detecting the noise countermeasure device is exerted. The calculation of the reliability will be described later.

Next, when the entrance detecting sensor 34 detects that the subject has left the toilet, the control device 22 transmits a signal to the data analyzing device 60 to start the data transmission by the transceiver 56. Upon receipt of this signal, the data analysis device 60 performs communication step S6.

In the communication step S6, the data analysis device 60 transmits the following notification data information to the server 12 via the Internet, that is, the identification information of the subject determined by the subject determination device 62, by each sensor. The detected data, the calculated reliability, the detection date information, the state information related to at least one aspect of the stool amount and the stool state detected by the defecation urination detection sensor 38, and the defecation history information. The server 12 records the received information in the database.

In addition, the control device 22 detects the sensor 34 by entering the room. After detecting that the subject has left the toilet, the post-test environment preparation step S7 is started.

The control device 22 detects the gas concentration by the odor gas sensor 26 in the post-detection environment conditioning step S7. Then, after the end of the defecation, even if the predetermined time has elapsed, and the gas concentration detected by the odor gas sensor 26 is still larger than the predetermined value, the control device 22 judges that the tub 2a of the flush toilet 2 is The stool is attached thereto, and the washing water stored in the washing water tank is discharged into the tub 2a by the toilet washing device 46 to clean the inside of the tub 2a, or the toilet removing device 48 generates the hypochlorite water or the like by tap water. Water, and spray the barrel 2a with sterilizing water to sterilize the barrel 2a.

The toilet washing device added by the toilet washing device 46 and the toilet body sterilization device 48 sterilize the tub body 2a, and can function as a residual gas removing device that reduces the residual odor gas concentration. Preferably, the cleaning power of the toilet cleaning automatically performed by the residual gas removing device is higher than the cleaning power of the normal toilet cleaning performed by the cleaning button (not shown) of the remote controller 8 operated by the subject. . Specifically, the number of times the toilet washing is performed by the residual gas removing device to discharge the washing water to the tub 2a is set to be large, or the set flow rate of the washing water can be increased. Further, the sterilizing ability of the residual gas removing device to sterilize the tub body 2a is set to be sterilized by the normal tub body 2a which is performed by the sterilizing button (not shown) of the remote controller 8 operated by the subject. The bactericidal ability is high. Specifically, the sterilization of the tub body 2a by the residual gas removing device is set to be higher than the usual sterilization spray, or the spray is performed. Sprinkle more water.

Further, after the end of the defecation, even if the predetermined time has elapsed, and the gas concentration detected by the odor gas sensor 26 is still larger than the predetermined value, the residual gas removing means judges that the inside of the pipe 18a is dirty, so that The pipe cleaner 58 starts working. The duct cleaner 58 cleans the inside of the duct 18a attached to the suction device 18 by using hypochlorous acid water or the like generated by tap water electrolysis.

Further, after the above cleaning and sterilization treatment, the gas concentration detected by the odor gas sensor 26 does not decrease, and when it is larger than a predetermined value, the residual gas removing device is on the display device 68. A message prompting to clean the toilet 2 is displayed.

Then, in the post-detection environment preparation step S7, the control device 22 controls the sensor heater 54, the suction device 18, and the toilet seat cover opening and closing device 40 to change to the detection standby mode, and ends the detection once.

Next, the physical condition display chart will be described with reference to Fig. 6. This physical condition display chart is a chart displayed by pressing the "detailed screen" button on the screen shown in Fig. 5.

In the storage device of the remote controller 8, a physical condition display chart, a defecation date of each subject corresponding to the subject identification information, and past detection data are recorded for each subject. The past detection data stored on the storage device on the remote controller 8 side may be data for the entire period of the defecation period, but, due to the capacity of the storage device, it is preferable that the defecation gas discharged during the initial excretion behavior during the defecation period Test data (test data during initial excretion).

As shown in Fig. 6, the physical condition display chart is a chart determined based on the experiment performed by the inventors described above, and the index indicated on the vertical axis of the chart is the odor gas as the first index (indicated as the physical condition). The index indicating the amount of gas in the case of the poor gas is an index relating to the amount of gas of the healthy gas as the second index. The first index is related to the amount of gas of the odor gas based on the first detection data detected by the gas detecting device 20, and the second index and the hydrogen gas as the health gas based on the second detection data detected by the gas detecting device 20. The amount of gas is related. On the graph indicating the physical condition of the vertical axis and the horizontal axis, the detection result of the defecation gas of the subject is displayed on the display device 68 of the remote controller 8 with time (time). In other words, as shown in Fig. 6, the mark indicating the latest detection result of the same subject is "1", the previous result is "2", and the previous result is "3"... The past 30 marks and the corresponding numbers. Therefore, the subject can recognize the temporal changes of his or her physical condition. Further, in the present embodiment, the amount is displayed 30 times, but it may be an amount of several weeks or several months, and it is considered that the development of cancer is in units of years, and therefore it may be in units of years. Further preferably, the subject can change the display range depending on the situation, and in the case where the display range is large, in consideration of the degree of easy viewing, it is needless to say that the monthly average data may be changed to display one year or two years. The method of quantity.

In addition, in the physical condition display chart, according to the relationship between the indicators related to the healthy gas and the indicators related to the odor gas, "suspected degree 2", "suspected degree 1", "body" are set. a multi-level area corresponding to the physical condition, such as a poor condition 2", "a poor physical condition 1", or a "good physical condition". Here, as shown in Fig. 6, with the worst The "suspected degree 2" corresponding to the physical condition is set in the upper left area where the amount of the odorous gas is the most in the physical condition display chart, and the amount of the healthy gas is the least. On the other hand, the best In the physical condition display chart, the amount of gas of the odorous gas is the least, and the amount of the gas of the healthy gas is the lowest in the lower right area. The area between the areas indicating the physical condition, "suspected degree 1", "poor state 2", and "poor state 1" is a band that is inclined upward to the right in the physical condition display chart. It is set in order from the upper left. The physical condition display chart is set in advance according to the weight, age, sex, etc. of the subject, and the marker points based on the first and second indicators are used. This physical condition is shown in the chart display, it can be detected based on data analysis activities and is detected by information.

As described above, in the present embodiment, the index of the amount of gas associated with the odor gas and the index relating to the amount of gas of the healthy gas are used, and by using these two indexes, the subject can be examined in more detail. Changes in physical condition or physical condition are assessed. For example, even if the amount of gas indicating a healthy gas with good physical condition is large, when the amount of gas of the odor gas is large, the physical condition is not evaluated as the best (the upper right range of the physical condition display chart). . On the contrary, even in the case where the amount of gas indicating a healthy body is very small, the amount of gas is very small. As long as the amount of gas of the odorous gas is small, the physical condition is not evaluated as the worst (the lower left range of the physical condition display chart).

In addition, for example, the "poor state of physical condition 1" and the boundary line indicating "poor physical condition 2" which is worse than its physical condition are drawn to the upper right so that the gas on the horizontal axis is a gas with a healthy gas. While the amount-related index is increasing, the index related to the amount of gas of the odor gas on the vertical axis is also increasing, indicating that the "poor state of the body 2" which is in poor physical condition is distributed on the boundary line. The side of the index associated with the amount of gas of the odorous gas is increased. In the present embodiment, even if the boundary line is the same as the amount of the gas of the healthy gas on the horizontal axis, the index value related to the amount of the gas of the odor gas on the vertical axis is the physical condition. The assessment is also different. Further, in order to obtain an equivalent evaluation, the value of the gas amount of the odor gas on the vertical axis increases, and the value of the gas amount of the healthy gas on the horizontal axis also needs to increase.

Further, on the storage device on the remote controller 8 side, suggestions corresponding to these physical conditions are recorded. Specifically, there is a suggestion of "please go to the hospital" for "suspected degree 2", "suggested to go to the hospital" for "suspected degree 1", and "the degree of poor health 2" If there is a risk of illness, please reduce your fatigue and improve your living habits as soon as possible. For the "poor health level 1", there is a suggestion that "the intestinal environment is not good, please pay attention to a healthy life". Good "has a suggestion that the body is in good condition." On the physical condition display chart, while the marker point showing the physical condition of the subject is displayed, a suggestion corresponding to the region where the latest marker point is located is displayed.

However, the marked points displayed on the physical condition display chart 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, or change, and are marked by a predetermined correction. The dot indicates the position after it was moved. Here, the hypothetical disease detected by the body information detecting system 1 of the present embodiment is colorectal cancer, and such a disease does not develop intensely within a few days. On the other hand, the body information detecting system 1 of the present embodiment sucks the defecation gas from the tub 2a of the flush toilet 2 provided in the restroom R, and the sucked gas is used for analysis, so that it is impossible to collect all the defecation. gas. In addition, when the subject uses the perfume, or if there is a gas such as an odor gas that reacts to the odor gas sensor 26 in the toilet R, the body condition may be detected for various reasons. The error occurs.

Therefore, based on the result of one test, if the displayed physical condition is greatly directed to the side where the physical condition is not good, the subject will be given an unnecessary psychological burden. In addition, if the detection result of each physical condition is greatly swayed, the test subject's trust in the physical condition detection result is lost. Therefore, in the body information detecting system 1 of the present embodiment, the analysis result of the data analysis device 60 is corrected so that the detection result of the display does not largely sway in accordance with the detection once. However, the detected data stored in the storage device of the remote controller 8 and the detected data transmitted and stored in the server 12 are stored together with the uncorrected data and the reliability of the detected data. In addition, in consideration of the next display, the storage device of the remote controller 8 can store display coordinates that have been corrected and displayed. As such, the body information detecting system 1 of the present embodiment obtains Not all of the information obtained is highly credible. However, the daily defecation behavior is continuously acquired for a long period of time, and the data is accumulated in the storage device and the server 12 of the remote controller 8, so that the long-term physical condition change of the subject can be detected, in the subject Before the physical condition deteriorates a lot, evoke its attention and not develop into a major disease such as colorectal cancer.

In this way, the correction of the detection data can suppress the fluctuation of the index of the physical condition of the subject output by the display device 68 due to an error or the like, and can function as an output stabilization device that stabilizes the output result.

Further, in the present embodiment, the detected data stored in the storage device of the remote controller 8 may not necessarily use the uncorrected data, and the corrected detected data may be recorded.

Next, the correction of the marker points will be described with reference to FIG.

(a) of FIG. 7 is a diagram showing an example in which the marked points of the latest data are moved by the correction, and (b) is a schematic diagram of limiting the amount of movement of the marked points.

First, as shown in (a) of Fig. 7, the mark point calculated by the data analysis device 60 based on the latest detection is "1", which greatly deviates from the center of gravity G of the mark point of the past 30 times of detection data.

In this way, if the marker point "1" which largely deviates from the distribution of the detection data up to the previous time is displayed, the subject will be overly psychologically burdened. The risk of cancer does not rise after a day, so A large change in the detected data like this is not so much the risk of cancer, but rather the result of the bad habits of the previous day, or most likely due to the detection of noise. Therefore, in the present embodiment, correction is made in consideration of not causing an excessive psychological burden to the subject. Therefore, when the latest detection result changes to the side of the physical condition (upper left), the data analysis device 60 displays the display position of the marker point "1" in the physical condition display chart based on the credibility of the current detection data. The predetermined distance is moved in the direction of the center of gravity G for display. That is, in the example shown in (a) of Fig. 7, the marker point "1" is moved in the direction of the center of gravity G (the side with good physical condition) to obtain the corrected marker point "1'", in which the marker is The latest inspection data is displayed at the position of "1'" (actually no marker point "1" is displayed). The smaller the credibility of the latest detection data, the greater the distance that the marker point "1" moves in the direction of the center of gravity G. In this way, by moving the latest marker point to the side indicating good physical condition, the psychological burden on the subject can be reduced. In addition, the calculation of the reliability of the detection data will be described later. However, when the latest marker point moves to the side of the physical condition for a predetermined number of times or more, the data analysis device 60 reduces the correction amount (the amount of movement due to the correction). Therefore, the subject can be made aware that his or her physical condition is deteriorating, and urges him to strive to improve his physical condition.

In addition, it is expected that a very large detection noise occurs when the latest body condition detection is performed, and in the case where the latest mark point is greatly deviated, even if (a) in Fig. 7 is performed The corrections stated, but the physical condition shown will still be to the body A large movement occurred on the bad side. Therefore, as shown in (b) of FIG. 7, a predetermined limit is set for the moving distance from the center of gravity G of the latest material. That is, the moving distance of the latest data from the center of gravity G is limited to ±40%, and even if the latest data deviates by more than 40% from the coordinates of the center of gravity G, the mark of the latest data is marked at a position deviating from 40%. point. For example, in the case where the coordinate value of the center of gravity G is (x, y), the range of the coordinate point of the latest data is (0.6x~1.4x, 0.6y~1.4y), and the deviation position of the above range is Do not mark points.

In addition, in the case where the movement of the latest data deviating more than 40% is continued for more than two times, the range in which the latest data can be moved is relaxed to 60%. Therefore, for example, when the coordinate value of the center of gravity G is (x, y), the range of the marker point coordinate value of the latest data is changed to (0.4x to 1.6x, 0.4y to 1.6y). This is because in the case where the large-scale movement of the latest data frequently occurs like this, it is not only the detection error but also the fact that it reflects that the subject's physical condition has undergone some change.

Next, the diagnosis chart on the server side will be described with reference to FIG. In addition, the following processing in the server is performed by the data analysis circuit in the server 12.

Fig. 8 is a view showing an example of a diagnosis chart displayed on the server side. As described above, in the body information detecting system 1 of the present embodiment, the detection data of the entire defecation period analyzed by the data analyzing device 60 is sequentially transmitted to the server 12 via the Internet, and the database on the server side is recorded. in. These stored test data can be displayed on the detected The medical institution terminal 16 provided by the registered medical institution or the like. For example, when the subject receives a suggestion of "recommended to the hospital" displayed by the display device 68 of the remote controller 8 and goes to the hospital for a visit, the diagnostic chart for the server can be displayed on the medical institution terminal 16. The vertical axis and the horizontal axis of the diagnostic chart and the vertical axis and the horizontal axis of the physical condition display chart displayed on the display device 68 of the remote controller 8 indicate the same index, but the physical conditions assigned to each range are more specific. By the medical institution terminal 16 referring to the test data of the subject recorded by the database on the server 12 side, the doctor can refer to the subject's temporal physical condition and contribute to the examination and treatment of the medical institution. Alternatively, the present invention may be constructed such that, in the case where the detected data transmitted to the server 12 indicates that the physical condition of the subject is significantly poor, the medical institution registered by the subject is detected to the subject. The user terminal 14 issues a notification that he or she is expected to come to the clinic.

The diagnostic chart displayed on the medical institution terminal 16 is different from the physical condition display chart displayed by the above-described subject's display device 68. As shown in Fig. 8, the diagnosis chart on the server 12 side is based on the graph determined by the experiments conducted by the inventors described above, and the relationship between the amount of gas of the healthy gas and the amount of the odor gas is established. The association of states. Specifically, in the diagnostic chart, the relationship between the amount of gas corresponding to the healthy gas and the amount of the odorous gas is set as follows: "the risk of colorectal cancer is large", "the risk of early colorectal cancer is large", "suspected early large intestine" "Cancer", "Poor health condition 3", "Body condition 2", "Body condition 1", "Health status", "Intestinal condition is poor (Kneeling)", and "Suspected misdiagnosis" ".

In the diagnostic chart on the server side thus set, the past detection data of the subject is marked in time (time), and the risk of colorectal cancer is large based on the position of the marker point, and the risk of early colorectal cancer is high. "The suspected early colorectal cancer" is a judgment about diseases such as cancer. In addition, the marked points displayed on the diagnosis chart on the server side have not been corrected or restricted, and the doctor makes a comprehensive judgment on the displayed data and its reliability. In addition, since the diagnostic chart and the judgment result displayed on the medical institution terminal 16 are set for the reference of the doctor, the name of the disease, the degree of development thereof, and the like are more specifically expressed. In addition, the position of the marker point is long-term, for example, "the risk of colorectal cancer is large", "the risk of early colorectal cancer is large", and the area of cancer and other diseases such as "suspected early colorectal cancer" indicates the possibility of disease. higher. The doctor can inform the subject of his or her physical condition after comprehensively judging the marked points and the credibility of the test. In addition, the medical institution terminal 16 can also be constructed as follows. In addition to displaying the diagnostic chart of the past detection data by time stamp (time stamp), the reliability of the reference database calculation can be displayed and detected by various sensors. The information obtained, at least the stool status information related to the aspect of the stool volume and the state of the stool, and the history of the defecation history.

Further, the server 12 is connected to the plurality of subject-side devices 10, and accumulated detection data of a plurality of subjects. In addition, when the subject visits the medical institution based on a certain test data, the result of the precise examination by the medical institution and the information about the symptom are also stored in the database on the server 12 side. Therefore, the data detected by the body information detecting system 1 of the present embodiment and the actual symptoms are accumulated in the server. 12 sides. Based on the detection data of a plurality of subjects accumulated as described above, the diagnosis chart is sequentially updated, and then based on the updated diagnosis chart, a higher-precision diagnosis can be performed. In addition, the physical condition display chart can also be updated based on the data on the server side. The physical condition display chart based on the information on the server 12 side is downloaded to the subject side device 10 via the Internet, and displayed on the display device 68 of the remote controller 8. However, even if the physical condition display chart is updated, the physical condition display chart directly displayed to the subject is corrected to an appropriate content that can be displayed to the subject.

Next, with reference to Fig. 9, the data detected by each sensor included in the body information detecting system 1 of the present embodiment and the estimation of the amount of gas based on these data will be described.

Fig. 9 is a schematic diagram showing detection signals of the respective sensors included in the body information detecting system 1 in the defecation behavior of the subject once. Shown on FIG. 9 is the detection signals of the respective sensors, from the top to the bottom, a hydrogen gas sensor 24, a carbon dioxide sensor 28, an odor gas sensor 26, a humidity sensor 30, The waveforms of the detection signals of the temperature sensor 32, the seating detection sensor 36, and the entrance detecting sensor 34.

The estimation of the amount of gas based on the detection signals of the respective sensors is performed by the data analysis device 60 as the physical condition determination device for determining the physical condition, that is, the CPU and the storage device built in the remote controller 8, or the server. The 12-side CPU and storage device are used. In the data analysis device 60, a start threshold and a stability threshold are set in advance, and the start threshold is read from the storage device in the remote controller 8 for judging excretion. The rate of change of the amount of gas at the start of the behavior, the stability threshold is associated with the amount of gas that can be stably detected. In addition, the excretion behavior mentioned here also includes the discharge of farts.

First, at time t _{1 of} Fig. 9, the entrance detecting sensor 34 detects whether or not the subject has entered the toilet. In a state where the entrance detecting sensor 34 detects that the subject is in the toilet (t ₀ to t ₁ ), the data analyzing device 60 detects the gas amount of the odor gas by the odor gas sensor 26. . Even in this state, the odor gas sensor 26 reacts due to the influence of the fragrance or the residual stool attached to the tub 2a of the flush toilet 2, and outputs a certain level of detection signal. In this manner, the detected value of the odor gas sensor 26 before the subject enters the toilet is used as the environmental standard value of the gas amount, that is, the residual gas detecting noise. Further, in a state before the entrance detecting sensor 34 detects that the subject enters the toilet, the odor gas sensor 26 and the suction device 18 are in a power-saving state, and the detecting portion of the odor gas sensor 26 is heated. The temperature of the sensor heater 54 is also set to be low, and the rotation speed of the suction fan 18c is also suppressed to lower the flow rate of the gas.

Next, at time t _1, the entrance detecting sensor 34 detects the test subject into the toilet, the odor gas sensor 26 and the suction means 18 into active state. Then, while the temperature of the sensor heater 54 of the odor gas sensor 26 rises, the rotation speed of the suction fan 18c also rises, and the suction of the gas of the predetermined flow rate is started. Therefore, the detected value of the temperature sensor 32 starts to rise to a suitable temperature after a temporary increase (the time t ₁ ~ in FIG. 9). Further, in the present specification, the period in which the entrance detecting sensor 34 detects that the subject enters the restroom R (times t ₁ to t _{8 in} FIG. 9) is referred to as a "defecation behavior". Further, after the subject enters the toilet, the detection signal detected by the odor gas sensor 26 rises. This is because the odor gas sensor 26 reacts to the body odor of the subject or the perfume, hair styling agent, and the like. In other words, the amount of residual gas detection noise that is detected before the subject enters the toilet R is detected by the subject of the subject. The detection noise detecting circuit provided in the data analysis device detects the residual gas detecting noise from the residual gas in the barrel 2a, and the detected subject from the subject detects the noise. Further, the odor gas sensor 26 is for detecting a very small amount of odor gas contained in the ppb level, and therefore the sensitivity is set to be very high, and the odor gas which is not noticeable to the human sense of smell is also react.

Next, at the time t _{2 of} Fig. 9, when the seat detecting sensor 36 detects that the subject is sitting on the toilet seat 4, the time point is set as the start time of the defecation period of the subject once. point. Further, in the present specification, the period in which the seat detecting sensor 36 detects that the subject is sitting on the toilet seat 4 (time t ₂ to t _{7 in} FIG. 9) is referred to as a "defecation period". Then, after the time point (time t ₂ ) at which the defecation period starts, and before the start of the first excretion behavior described later (time t _{5 of} FIG. 9), the odor gas sensor 26 The detected value is set to (as) the standard value of the residual gas.

In the example in FIG. 9, after the time t ₂ is detected by the seating, between the time t ₃ ~ t _4, the detected value of the humidity sensor 30 is rising. This is because the detected person is detected to be urinating, and the detected value of the odor gas sensor 26 is substantially unchanged, and therefore, the data analyzing device 60 judges that the excretion behavior has not been performed. Next, at time t ₅ sharp rise in hydrogen gas sensor 24 and the detected value of the odor of the gas sensor 26. As described above, when the detected value of the odor gas sensor 26 suddenly rises during the defecation period after the subject is seated, the data analysis device 60 determines that the excretion behavior is already being performed.

When the subject performs the excretion behavior, the portion added from the standard value of the residual gas in the detected value of the odor gas sensor 26 (the oblique portion of the detected value chart of the odor gas sensor 26) changes The amplitude, data analysis device 60 estimates the amount of odor gas discharged by the subject. In other words, the data analysis device 60 sets the detected data value at the start time of the defecation period of the subject as a standard value of the detected noise level from the subject, from the time when the excretion behavior starts until the end of the excretion behavior. At the point, the difference between the detected value detected by the odor gas sensor and the standard value is integrated over time, and the amount of odor gas accompanying the first excretion behavior is estimated. In this way, since the data analysis device 60 estimates the odor gas amount based on the difference between the detected value and the standard value, it is possible to suppress the influence of the detection noise originating from the subject. Thus, the circuit provided in the data analysis device 60 that performs this calculation functions as a second noise detecting device that reduces the influence of the detected noise by the detected noise suppressing circuit. Further, when the detection noise level originating from the subject is greater than or equal to a predetermined value, the data analysis device 60 notifies the situation by the display device 68. In addition, the estimation of the amount of odor gas will be described in detail later. Similarly, the data analysis device 60 estimates the amount of gas of the hydrogen gas discharged from the subject based on the amount of increase in the standard value of the residual gas from the detected value of the hydrogen gas sensor 24. In the excretion behavior of the test subject (Fig. 9 time t ₅₎ After completion of the odor gas sensor 26 and the detected value of the hydrogen gas sensor 24 is returned to the standard value of residual gas. Next, at time t _6, when the behavior is excreted 2nd test subject, odor gas sensor 26, the carbon dioxide sensor 28, the detection value of the hydrogen gas sensor 24 rises again sharply. Similarly to the first excretion behavior, the second excretion behavior estimates the amount of the odor gas and the hydrogen gas discharged by the subject based on the increase amount from the standard value of the residual gas. In addition, when estimating the amount of odor gas gas and hydrogen gas amount of the excretion behavior after the second time (including the second time), it is possible to change the behavior of each excretion in consideration of the influence of the floating float floating on the water surface of the barrel. standard value.

In this way, when the subject enters the toilet and performs a plurality of excretion behaviors (that is, when the amount of gas having a predetermined threshold or more is detected multiple times), the excretion behavior accompanying each discharge is similarly estimated. Defecation gas. In addition, in calculating the amount of defecation gas of the excretion behavior after the second time (including the second time), the standard value can be changed for each excretion behavior in consideration of the influence of floating floating on the water surface in the barrel.

Next, at time t ₇ of FIG. 9 is detected by the seating detection sensor 36 is detected to leave the toilet seat, one end during defecation, at time t ₈ 34 detected by the entrance detecting sensor is detected to leave In the toilet, the defecation behavior ends. The data analysis device 60 estimates the amount of defecation gas accompanying each excretion behavior until the entrance detecting sensor 34 detects that the subject has left the toilet.

Based on the amount of defecation gas thus detected, the physical condition of the subject is determined in the remote controller 8 and the server 12. At this time, it is preferable that the physical condition detection of the subject can be immediately displayed on the side of the remote controller 8 during the defecation period or after the end of the defecation period. Further, after a plurality of excretion behaviors, since the stool is accumulated in the tub 2a, the detection accuracy of the amount of the odorous gas is lowered. On the other hand, when the first excretion behavior is performed, the defecation gas that reaches the lowermost end of the large intestine is discharged, so that the most useful information for detecting the physical condition can be obtained, and the reliability of the detection is high. On the basis of the above, when the amount of defecation gas (the amount of odor gas and hydrogen gas) of the first excretion behavior is estimated on the side of the remote controller 8, the amount of defecation gas based on the first excretion behavior is The physical condition of the examiner is detected and displayed on the display device 68 of the remote controller 8. Alternatively, in one defecation behavior, the weight of the test data related to the first excretion behavior may be greater than the weight of the test data related to the later excretion behavior in the physical condition detection.

On the other hand, it is preferable to perform more accurate judgment in the server 12 by using the total amount of defecation gas for a plurality of excretion behaviors. Therefore, in the server 12, the total amount of defecation gas based on the plurality of excretion behaviors (the total amount of the odor gas and the gas amount of the hydrogen gas) is more preferably based on the detection of the subject from the seating on the toilet seat. The total amount of defecation gas in all excretion behaviors included in one bowel movement until the seat is left, and the physical condition of the examiner is judged. In addition, the determination of the physical condition of the examiner performed on the server 12 side does not necessarily have to be the total amount of defecation gas of all excretion behaviors included in one defecation period, but preferably, based on multiple defecations. The total amount of defecation gas for all excretions contained during the period.

Here, as shown in the example of Fig. 9, the standard value of the residual gas is a constant value. However, when the standard value of the residual gas is not a constant value, the discharge amount of the odor gas can be estimated. For example, in the case where the detected value detected by the odor gas sensor 26 has a tendency to increase, as shown in Fig. 10(a), it is assumed that the odor gas sensor 26 detects before the start of the excretion behavior. The rate of change of the detected value is continuous before and after the excretion behavior, and the auxiliary line A is drawn on the assumption that the auxiliary line A is a standard value. The amount of gas of the odor gas can be estimated from the time when the slope of the detected value detected by the odor gas sensor 26 is greatly changed from the time when the auxiliary line A greatly changes as the first excretion behavior.

Further, since the residual gas before the excretion behavior is set as a standard value and the amount of the odor gas is estimated based on the difference from the standard value, it is preferable that the standard value does not change too much. Therefore, before the time point at which the excretion behavior starts, the rate of change of the detected value detected by the odor gas sensor 26 (that is, the rate of change of the standard value = the slope of the auxiliary line A) is below a predetermined threshold The data analysis device 60 displays a meaning indicating that the estimation accuracy of the amount of defecation gas is high by the notification device constituted by the display device 68 of the remote controller 8 or the speaker 70.

On the other hand, in the case of spraying a spray-type fragrance immediately before the discharge operation, or in the case of a sterilizing cleaning cloth or spray using an ethanol-based toilet seat sterilizing agent, the odor gas sensor is used before the excretion behavior The detected values detected by 26 will vary greatly. If the detection value in such a state is set to the standard value, the odor can not be obtained. The amount of gas in the body is estimated. Therefore, in the case where the standard value of the detection noise level originating from the subject is equal to or greater than the predetermined value, or the rate of change of the standard value is equal to or greater than the predetermined threshold, the data analysis device 60 is controlled by the remote controller 8 The notification device constituted by the display device 68 or the speaker 70 indicates that the estimation accuracy of the amount of defecation gas is low. On the other hand, when the excretion behavior is performed after such notification, the detection for the physical condition analysis is not performed, or the reliability of the detection is set to be low.

Next, a case where the ethanol-based toilet seat sterilizing agent is detected will be described with reference to Fig. 10(b). 10(b) is a graph showing an example of the detected value detected by the odor gas sensor 26 when the subject uses the ethanol-based toilet seat sterilizing agent.

First, T _10, is into the toilet odor gas sensor 26 of the detection value detected by the odor of the reaction or the like occurs at the time of FIG. 10 (b) is detected by the entrance detecting sensor 34 is detected by the Start to rise steadily. Next, at time t _11, when the toilet seat removed using alcohol-based bactericide antiseptic cleaning cloth by detecting the odor gas sensor 26 pairs of ethanol reacts taste, a sharp rise in the detected value. After the time t _12, is detected by the end of the toilet seat 4 sterilization, the sterilizing cloth thrown barrel body 2a, alcohol-based due to the high volatility odor gas sensor 26 detected value starts to decrease. Since this characteristic is different from the residual odor gas component, the inventors have found that the surge in the detection value due to the sterilization using ethanol can be detected by waiting for a while, which is detectable. However, a sterilizing cleaning cloth using an ethanol-based toilet seat sterilizing agent may float on the water surface when it is thrown away after sterilization. Since the ethanol continues to volatilize in this case, the decrease in the detected value tends to be delayed. Therefore, it is preferable to discharge the sterilizing cleaning cloth as follows.

Next, at time t _13, is detected by the seating detection sensor 36 to the seated person is detected in the toilet seat, it is detected by operating the remote cleaning button 8 (not shown on FIG.) Water washing toilet 2, the discharge The sterilizing cleaning cloth floating in the water of the tub body 2a causes the detected value of the odor gas sensor 26 to drastically decrease. In the case of using an ethanol type toilet seat sterilizing agent, the detected value of the odor gas sensor 26 is basically changed as described above.

Therefore, the toilet seat sterilization detecting circuit provided in the data analyzing device 60, after the entrance detecting sensor 34 detects that the subject enters the toilet, the seat detecting sensor 36 detects that the subject is seated on the toilet seat, When the detected value of the odor gas sensor 26 suddenly rises above a predetermined value, it is judged that the subject sterilizes the toilet seat 4 using the ethanol type toilet seat sterilizing agent. As such, the inventors of the present invention have found that by the detection signals of the entrance detecting sensor 34, the seating detecting sensor 36, and the odor gas sensor 26, it is possible to detect the pair of the subject being performed in the toilet R. The toilet seat 4 performs a unique behavior such as sterilization.

In addition, when the toilet seat sterilization detecting circuit detects that the ethanol type toilet seat sterilizing agent is used, and the detected person does not wash the water washing type toilet 2 at a predetermined time after sitting, the data analyzing device 60 is provided. The sterilization detection noise response circuit will send a signal to the toilet cleaning device 46 to automatically perform toilet cleaning. Moreover, after the toilet seat sterilization detection circuit detects the use of the ethanol type toilet seat sterilizing agent, the sterilization detection noise The response circuit will increase the speed of the suction fan 18c. Thereby, the amount of gas sucked by the suction device 18 is increased, and the ethanol component volatilized by the toilet seat is actively deodorized by the deodorizing screening program 78, thereby reducing the detection of the odor gas sensor 26. value. That is, after the toilet seat sterilization detecting circuit detects that the toilet seat sterilizing agent is performed, the sterilizing detecting noise countermeasure circuit starts the deodorizing device to reduce the detection noise from the ethanol type toilet seat sterilizing agent.

Further, when the toilet seat sterilization detecting circuit detects that the ethanol type toilet seat sterilizing agent is used and the detected value of the odor gas sensor 26 rises, the sterilizing detecting noise countermeasure circuit stops the detection of the physical condition, and The display device 68 displays a message to wait for the defecation to inform the subject. Before the physical condition detection is possible, the sterilization detection noise response circuit displays information indicating that the subject is slightly defecation on the display device 68. Therefore, the detection noise from the ethanol-based toilet seat sterilizing agent can be alleviated. On the other hand, the detected value of the odor gas sensor 26 which is rapidly increased by using the ethanol-based toilet seat sterilizing agent starts to decrease after the subject has finished sterilizing.

After the detection noise level detected by the odor gas sensor 26 is turned to decrease, the sterilizing detection noise countermeasure circuit eliminates the information indicated by the meaning of the slight defecation displayed on the display device 68, and informs that the detection can be performed. The meaning of the meaning. In other words, in the case where the detection noise level derived from the ethanol-based toilet seat sterilizing agent tends to decrease, it is possible to detect an increase in the detected value of the odor gas sensor 26 having a tendency to decrease. The data analysis device 60 detects the rise of the detected value of the odor gas sensor 26 having a reduced tendency as the subject emits the defecation gas. but When the detection noise level detected by the odor gas sensor 26 is lower than the predetermined rate of change, the sterilizing detection noise countermeasure circuit stops the detection of the physical condition and continues to display on the display device 68. Please wait for the message of defecation. That is, in the state where the detection noise level is drastically lowered, the detected value rise due to the discharged defecation gas is masked, and the discharge of the defecation gas cannot be correctly detected. In addition, when the standard value is greatly reduced, the calculation error is increased, so it is preferable to suspend the detection.

In addition, due to the use of the ethanol-based toilet seat sterilizing agent, the sterilizing detection noise countermeasure circuit suspends the measurement for detecting the physical condition when the detection noise level is equal to or greater than a predetermined value, or sets the detection reliability to low. As described above, when the detection reliability is set to be low, the marker point on the physical condition display chart described in Fig. 7(a) is corrected to a larger extent toward the side indicating that the physical condition is good. That is, after detecting that the toilet seat is sterilized, the sterilizing detection noise countermeasure circuit corrects the physical condition outputted by the display device 68 to the side indicating that the physical condition is good.

Further, when there is a lot of stool attached to the flush toilet 2 or a large amount of the fragrance is used, the absolute value of the amount of gas detected by the odor gas sensor 26 becomes large, and there may be a sensor depending on the situation. The detected value is saturated, or the detection accuracy deviates from the high-precision range. Therefore, in this case, it is difficult to accurately estimate only a small amount of odor gas. Therefore, in the case where the absolute amount of the standard value is equal to or greater than the predetermined threshold, the data analysis device 60 does not perform the detection for detecting the physical condition, or sets the detection reliability to be low.

Further, in the database of the server 12, the detection data of the odor gas gas amount and the health gas gas amount of the new subject as described above are successively accumulated. Further, in the database of the server 12, the cancer diagnosis result of the subject from the medical institution terminal 16 in the medical institution is associated with the identification information of the subject and recorded. Based on such a cancer diagnosis result, the server 12 updates the recorded diagnosis chart with the history of the change in the amount of the odor gas and the health gas.

Figure 11 shows an example of updating the diagnostic chart. For example, the test result data of the odor gas and the healthy gas in the old diagnostic chart is marked and analyzed, and the subject is judged to be "suspected early colorectal cancer", but based on the diagnosis result This patient has developed early colorectal cancer. In this case, as shown in Figure 11, expand the area of "high risk of colorectal cancer", "risk of early colorectal cancer", "suspected early colorectal cancer", and narrow the area of "poor health" The portion corresponding to the test data A of the patient diagnosed as having had early colorectal cancer is included in the above-mentioned region of expansion. In contrast, for example, on the old diagnostic chart, even if the correlation between the odor gas and the amount of the gas of the healthy gas is made, the judgment of "suspected early colorectal cancer" is made, and according to the diagnosis result, it is diagnosed as not In the case of suspected patients with cancer, the expansion of the "poor state of the body" region, narrowing the risk of "large risk of colorectal cancer", "risk of early colorectal cancer", "suspected early colorectal cancer" region. In addition, in the case of updating the diagnostic chart, each area of the physical condition display chart is also performed. The same change.

In addition, the attribute information of the weight, age, sex, and the like of the subject, and the change history of the detection data of the odor gas and the health gas are inclined, and the server 12 records a plurality of conditions that are separated by conditions. The physical condition shows a chart.

Further, in the subject-side device 10, when it is desired to perform a more detailed physical condition analysis, the server 12 registers attribute information such as the weight, age, sex, and the like of the subject with the subject identification information. Then, when the detection data of the subject who wants to perform the detailed physical condition analysis is accumulated in the server 12, the server 12 selects the physical condition display that is close to the attribute information of the subject and the change history of the detected data. chart. The server 12 transmits the selected physical condition display chart to the subject side device 10 via the Internet. After receiving the new body condition display chart from the server 12, the subject side device 10 changes the already stored body condition display chart to the received new body condition display chart. Therefore, in the subject-side device 10, a more accurate physical condition analysis can be performed based on the attribute of the subject and the change history of the detected data.

Further, in the embodiment described above, the change history of the detected data is also stored in the subject-side device 10. However, the present invention is not limited thereto, and the detected data may be stored only in the database of the server 12. The subject-side device 10 reads the change history of the past test data from the database of the server 12, and performs the diagnosis result calculation and the time-lapse diagnosis (diagnosis over time) in the diagnosis step S5.

Here, the method of calculating the reliability in the diagnosis step S5 of Fig. 4 will be described in detail. The semiconductor gas sensor used as the odor gas sensor 26 has a feature that not only the odor gas but also the odor gas surrounding the sterilizing cleaning cloth and the object to be detected can be detected. An odorous gas attached to the body or clothing. Further, the detected value of the odor gas detected by the semiconductor gas sensor changes depending on the state of the stool (for example, whether it is a state of squatting) or the amount of stool. Therefore, in addition to the judgment on the disease of cancer, it is also required to evaluate the magnitude of the influence of the detection noise of these odorous gases or the state of the stool. In the present embodiment, the data analysis device 60 of the subject-side device 10 installed in the toilet is provided with a reliability determination circuit that evaluates the odor gas detection that affects the defecation gas. The noise, the state of the stool, and the like affect the detection accuracy, and the reliability of the detection is judged as an accuracy index indicating the gas detection by the gas detecting device 20.

Fig. 12 is a view for explaining a method of judging the reliability of detection. In the following description, the correction of the influence of the odor gas adhering to the body or clothing of the subject, the influence of the humidity, the influence of the temperature, and the number of times of the defecation gas will be described as an example. The determination of the reliability of the detection is performed by a reliability determination circuit that determines the reliability of the detection of the odor gas in the data analysis device 60 provided in the remote controller 8.

Hydrogen gas sensor 24, odor gas sensor 26, carbon dioxide sensor 28, humidity sensor 30, temperature by detection device 6 The outputs of the degree sensor 32, the entrance detecting sensor 34, the seating detecting sensor 36, and the defecation urination detecting sensor 38 are sent to the data analyzing device 60 of the remote controller 8. An example of the output of these sensors is shown on Fig. 12.

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

The figure 13 to the figure 16 show the odor control gas detection noise correction chart and the humidity correction for judging the influence of humidity on the subject to determine the influence of the odor gas adhering to the body or clothing of the subject. A chart, a temperature correction chart for judging the influence of temperature, and a correction chart for the number of times of draining the influence of the number of times of drainage.

As the semiconductor gas sensor used in the odor gas sensor 26, odor detection noise (environment detection noise) attached to the detector other than the defecation gas can be detected. It can be said that when the amount of the odor gas component (detection noise amount) to which the subject is attached is large, the detection reliability is lowered. Therefore, as shown in Fig. 13, in the detected odor gas detection noise correction chart of the subject, a correction value is set for the noise level of the adhesion odor gas detection. Specifically, the correction value 1 and the undetectable (correction value 0) are set in the graph, wherein the correction value 1 is a value that is not corrected when the amount of the odor gas component attached to the subject does not reach the predetermined value. On the other hand, when the amount of the odor gas component adhered by the subject reaches a predetermined value or more, the negative correction amount from 1 is increased to gradually decrease the reliability value as the amount of the odor gas component increases. When the detection noise amount of the odor gas component attached to the subject exceeds a predetermined amount, the system cannot detect (correction value 0). Attached odor gas detection noise amount, based on seat detection The sensor 36 detects the non-defecation period before the subject is seated on the toilet, and is determined by the detection data detected by the odor gas sensor 26. In addition, the odor gas component adhered by the subject affects not only a part of the defecation period but the entire period of the defecation period. Therefore, the reliability is corrected from the beginning to the end of the defecation period. Hereinafter, the credibility correction performed during the entire defecation period is referred to as "whole correction".

Further, the humidity of the tub body 2a after the urination of the subject increases, and the humidity of the gas reaching the detecting portion of the odor gas sensor 26 also increases. When the humidity of the gas reaching the odor gas sensor 26 rises, the resistance of the odor gas sensor 26 changes, and the sensitivity of the sensor decreases. Further, after the stool adhered to the tub 2a is drenched with urine, the adhered stool becomes soft from a dry state, and during the urination, the adhered stool temporarily releases a large amount of defecation gas into the tub 2a. The defecation gas discharged from the attached stool is detected as noise when detecting the defecation gas discharged from the subject, and is detected by the odor gas sensor 26. Therefore, as shown in Fig. 14, in the humidity correction map, the humidity detected by the humidity sensor 30 is corrected to be 1 when the humidity is lower than the predetermined value, and the humidity is greater than or equal to the predetermined value. The higher the confidence, the lower the reliability. When the detection threshold is above, the system cannot detect it (correction value 0). In addition, since the urination behavior is only temporary, the humidity correction map is only "partial correction", that is, correction is performed only when the humidity detected by the humidity sensor 30 is changed. In addition, hereinafter, the correction of the reliability is made only during a specific period of the defecation period, or although it is performed during the entire defecation period, but is not performed during each period of the defecation period. The same as the amendment, called "partial correction."

Further, the semiconductor gas sensor used as the odor gas sensor 26 is composed of tin oxide, and the detection portion thereof is detected by the oxidation-reduction reaction of oxygen and reducing gas adsorbed on the surface while the detecting portion is heated. An odorous gas. Therefore, if the temperature of the detecting portion is higher or lower than a predetermined temperature range, the sensitivity of the sensor is lowered. Therefore, as shown in Fig. 15, in the temperature correction map, the correction value is set corresponding to the temperature detected by the temperature sensor 32. Specifically, when the temperature detected by the temperature sensor 32 is within a suitable temperature range suitable for detection by the detecting portion of the odor gas sensor 26, the correction value is set to a value larger than 1 to improve The reliability is such that when the temperature detected by the temperature sensor 32 is slightly higher or lower than the temperature range detected by the detecting portion of the odor gas sensor 26, the correction value is regarded as a value less than one. In order to reduce the reliability, and further, when the temperature detected by the temperature sensor 32 is in a range larger than the upper limit of the temperature that can be detected, or in a range smaller than the lower limit of the temperature that can be detected. Next, it cannot be detected as a system (correction value 0). In addition, since there is not much variation during defecation, the temperature correction is an overall correction made during the entire defecation period.

Further, as described above, in the case of performing the excretion behavior a plurality of times during the defecation period, the amount of defecation gas in the first excretion behavior is large (the amount of the odor gas is also large), and therefore, during the defecation period. The initial excretion behavior is more accurate than the later excretion behavior. Therefore, as shown in Fig. 16, in the excretion behavior number correction chart (excretion frequency correction chart), in order to improve the reliability of the initial defecation gas, the correction value is It is set to a value larger than 1, and the second time is 1, and the third time is a value of less than one. As the number of times increases, the correction value gradually decreases. Therefore, this is a method in which the first defecation gas is used as a priority diagnostic object. In addition, the excretion behavior number correction chart is corrected only when the defecation gas is detected, so it is partially corrected.

12, at time t _1, when the entrance detecting sensor 34 detects that the test subject into the toilet, the control device 6 detecting means 22 detects a standby state before the detection step proceeds Environment Development start preparing step, The sensor heater 54 and the suction device 18 are driven. Thereby, the temperature detected by the temperature sensor 32 rises and converges to a suitable temperature. Then, during the non-defecation period before the seat detection sensor 36 detects that the subject is seated on the toilet, the data analysis device 60 of the remote controller 8 refers to the temperature correction map to obtain the convergence temperature detected by the temperature sensor 32. Corrected value. In the example of Fig. 12, the temperature correction value is 0.9.

After the addition, after time t _1, the test subject into the toilet, because the noise detected odor (smell gas detector noise) is attached to a test subject, the odor from the gas sensor 26 detected detection data increases in , converges to a certain value. Then, at time t ₂ , the seat detecting sensor 36 detects that the subject is seated on the toilet. Based on the detection data detected by the odor gas sensor 26 during the non-defecation period before the seat detection sensor 36 detects that the subject is seated in the toilet, the data analysis device 60 of the remote controller 8 obtains the correction value. In the present embodiment, the odor gas detection noise correction value attached to the subject is 0.7.

Next, t _3, the seating detection sensor 36 is detected during the test subject is seated on the toilet after defecation, urination when the test subject, the detected value of the humidity sensor 30 rises at a time. In addition, the detection of the increase in humidity by the humidity sensor 30 can be performed, for example, before the defecation period, that is, the humidity at which the seat detecting sensor 36 detects that the subject is seated on the toilet is a standard value. As described above, when the humidity sensor 30 detects that the detected data has risen, the data analysis device 60 refers to the humidity correction map to obtain a correction value corresponding to the detected detection data. In the present embodiment, the partial correction value (i.e., time t ₃ to t ₄ ) during the humidity rise period detected by the humidity sensor 30 is 0.6.

Next, at time t ₅ , t ₆ , since the subject performs the excretion behavior, when the rate of change of the difference between the detected data and the standard value detected by the odor gas sensor 26 is greater than or equal to a predetermined value, the data The analysis device 60 calculates the amount of gas accompanying this excretion behavior. In addition, at the same time, the data analysis device 60 sets the correction value of the reference number of times based on the number of times of the excretion behavior during the defecation period, and sets the correction value of the period corresponding to the first excretion behavior (that is, the time t ₅ to t ₅ '). At 1.5, the correction value for the period corresponding to the second excretion behavior (that is, the time t ₆ to t ₆ ') is 1.0.

Based on the total correction value and the partial correction value estimated as described above, the data analysis device 60 calculates the detection reliability of the detection of the amount of gas accompanying each excretion behavior. In the present embodiment, 3 is used as the criterion of the reliability, and the reliability of each excretion behavior is calculated by the product of all the correction values of 3×all and the corresponding partial correction values. . Specifically, the reliability of the first excretion behavior is 3 (standard) × 0.9 (temperature correction value) × 0.7 (detection of the attachment detection noise correction) Value) × 1.5 (number of times correction value) = 2.84. In addition, the reliability of the second excretion behavior is 3 (standard) × 0.9 (temperature correction value) × 0.7 (detection detection detection noise correction value) × 1.0 (number of times correction value) = 1.89.

Then, the reliability calculated as described above is displayed by the display device 68 of the remote controller 8 as explained with reference to FIG. Further, the calculated reliability, together with the detection data of the odor gas sensor 26 and the detection data of the hydrogen gas sensor 24, is transmitted from the subject side device to the server 12, and is recorded in the server. 12 in the defecation gas database. In addition, at this time, the detection data of the odor gas sensor recorded in the defecation gas database of the server 12 and the detection data of the hydrogen gas sensor are originals which are not corrected according to the credibility described later. data. Then, when the medical data is connected to the medical institution terminal 16 connected to the server 12, together with the detection data of the odor gas sensor 26 and the detection data of the hydrogen gas sensor 24, the reliability of the detection is also display. The doctor of the medical institution diagnoses the detected reliability with reference to the detection data of the odor gas sensor 26 and the detection data of the hydrogen gas sensor 24. Therefore, when doctors diagnose the physical condition of the subject based on the test data, it is possible to use a test with high reliability data to perform a more accurate diagnosis. In addition, doctors may not use or pay attention to the detection of low-confidence data for diagnosis. Further, when the reliability of the detection data is less than or equal to one part or the entire period, the detection accuracy is low, and therefore the detection data cannot be transmitted to the server 12 as the system cannot detect.

Then, based on the detection calculated like this, The reliability is corrected for the detection data of the odor gas sensor 26 and the detection data of the hydrogen gas sensor 24. Specifically, when the detection reliability is high, the actual detection value is used, but when the detection reliability is low, the detection value is corrected so as to be close to the past value. For example, when the body condition analysis is performed based on the detection data of the defecation gas accompanying the first excretion behavior on the subject side device 10, in order to make the detection data more close to the storage device of the remote controller 8 The past detection data, and the newly detected detection value is corrected. As described above, the reliability with the first excretion behavior was calculated to be 2.84.

Based on the credibility calculated as such, the data analysis device 60 determines the amount of correction for the detected value. Fig. 17 is a view showing a correction chart showing the relationship between the reliability stored by the data analysis device and the correction rate of the detected value. As shown in the figure, for example, in the present embodiment, when the reliability is 1 or less, since the reliability of the detected data is too low, the detected value cannot be used. That is, the physical condition analysis is not performed based on the detection data of the period in which the reliability is equal to or less than the predetermined value, and the physical condition analysis is performed based only on the detection data whose reliability is greater than the predetermined value, and the analysis result is displayed on the display device 68. In addition, when the reliability is greater than 1 and 2 or less, the detection value is corrected by approaching 20% of the past history side. In addition, when the reliability is greater than 2 and not more than 3, the detected value is corrected by approaching 15% of the past history side. In addition, when the reliability is greater than 3 and 4 or less, the detection value is corrected by approaching 10% of the past history side. In addition, when the reliability is greater than 4 and 5 or less, the detection value is corrected by approaching 5% of the past history side. In addition, inspect When the reliability of the measured data is greater than 5, the detected value is not directly corrected.

In the above example, the reliability of the first excretion behavior was 2.84. Therefore, as explained with reference to Fig. 7(a), the correction of the detected value of the latest data to the past is made close to 15%, and is displayed together with the past data.

In addition, correction based on such reliability may be performed on the server 12 side. Further, when the physical condition analysis is performed on the side of the server 12, for example, the odor gas detection data and the hydrogen gas detection data of the excretion behavior whose reliability is equal to or greater than a predetermined value may be accumulated in one defecation period, and based on the accumulated data. Perform a physical condition analysis. Further, the detection data stored in the storage device of the remote controller 8 is not necessarily uncorrected, and the corrected detection data may be stored.

The correction chart is not limited to the above-described subject-attached odor gas detection noise correction chart, temperature correction chart, and humidity correction chart. Figures 18 to 29 are diagrams of examples of correction charts.

For example, when there is an odor detection noise (environmental detection noise) other than the defecation gas such as a fragrance in the toilet, the odor gas sensor 26 detects the odor detection noise, which causes a decrease in detection accuracy. . Therefore, the data analysis device 60 performs a reliability correction for evaluating the influence of the environmental detection noise. In addition, the detection noise amount of such environmental detection noise can be performed, for example, based on the detection data detected by the odor gas sensor 26 before the entrance detecting sensor 34 detects that the subject enters the toilet. Evaluation. Figure 18 is a diagram showing the environmental detection noise correction chart. Figure. As shown in the figure, the environmental detection noise correction value is set to 1 when the detection noise of the environmental detection noise is smaller than a predetermined value, and the detection noise amount of the environmental detection noise becomes greater than a predetermined value. In order to reduce the credibility, the correction factor is made smaller. Then, when the detection noise of the environmental detection noise is above the upper limit that can be detected, the system cannot detect it. In addition, since the environmental detection noise affects the entire defecation period, the correction value of the environmental detection noise can be a total correction.

Further, for example, when a spray type fragrance is used, when the standard value is set, the detection data of the odor gas sensor 26 greatly changes, or the slope of the standard value set when the gas amount is estimated is large. In the case, the accuracy of the estimated amount of gas will decrease. Therefore, with reference to the standard value stability correction map, the data analysis device 60 evaluates the influence of the state in which the standard value stability is poor (referred to as a standard value stability defect), and corrects the reliability. When the standard value stability is evaluated, for example, the magnitude of the variation of the standard value with respect to the time axis during the non-defecation period or the detection data of the odor gas sensor 26 when the standard value is set may be used. Figure 19 shows the standard value stability correction chart. As shown in the figure, the standard value stability detection noise correction value is 1 when the standard value stability is small, and the smaller the standard value stability is, the smaller the correction value is. Then, when the degree of stability of the standard value stability reaches a predetermined value or more, the system cannot detect it. In addition, the estimation of the amount of gas is to set a standard value for each excretion behavior, and the correction value is only for the period corresponding to each excretion behavior, and therefore is a partial correction.

In addition, for example, cleaning the toilet with a sterilizing cleaning cloth In the case of a seat, components such as ethanol contained in the sterilizing cleaning cloth are detected by the odor gas sensor 26. The influence of the components such as ethanol contained in the sterilizing cleaning cloth is that the odor gas sensor 26 detects a large detection value immediately after the sterilizing cleaning cloth is used, but since the ethanol is highly volatile, the odor is in a short time. The detected value of the gas sensor 26 is again lowered. Therefore, with reference to the toilet seat sterilization cleaning correction chart, the data analysis device 60 corrects the reliability that is affected by the sterilization of the toilet seat. In addition, after the entrance detecting sensor 34 detects that the subject enters the toilet, the seat detecting sensor 36 detects the use of the sterilizing cleaning cloth before detecting the seated on the toilet seat, for example, by detecting the smell The detected value of the taste gas sensor 26 is known to vary greatly from the predetermined value. Figure 20 is a diagram of the toilet seat sterilization cleaning correction chart. When it is detected that the sterilizing cleaning cloth is used, the predetermined period is not detected as the system (correction value 0) from the detection of the use of the sterilizing cleaning cloth, and the correction value in the subsequent period is less than 1 It started to rise to 1 as time passed. In addition, since the influence of the sterilizing cleaning cloth changes with time as described above, it is a partial correction.

Further, since the defecation gas contains only a trace amount of the odor gas, the more the odor gas discharged during the defecation period, the more accurate the physical condition analysis can be performed. Therefore, referring to the defecation gas total amount correction map, the data analysis device 60 corrects the reliability based on the total amount of the odor gas. In addition, the total amount of defecation gas can be evaluated by the sum of the amounts of gas estimated based on the detection data of the odor gas sensor during the defecation period. Fig. 21 is a view showing a correction chart of the total amount of defecation gas. As shown in the figure, the total amount of defecation gas is corrected, and the total amount of defecation gas is above a predetermined value. In the meantime, it is considered that a certain problem such as aroma sprayer spray occurs during the test, and the system cannot detect it (correction value 0). When the total amount of defecation gas is less than a predetermined value, it is considered that the defecation gas is very small, and the system cannot detect it. (corrected value 0). Then, in the range that is not judged to be undetectable by the system, when the total amount of defecation gas is large, the correction value is 1, and the correction value becomes smaller as the total amount of defecation gas decreases. In addition, the correction of the total amount of defecation gas is a total correction because it sets the correction value based on the total amount of defecation gas during the entire defecation period.

In addition, since a large amount of defecation gas is discharged into the barrel when the fart is discharged, the defecation gas generated by the fart is very suitable for the analysis of the physical condition. Therefore, when detecting that the subject is discharging the fart, the data analysis device 60 refers to the fart correction value map and corrects the reliability of the period in which the fart is discharged based on the amount of the defecation gas contained in the fart. In addition, for the behavior of discharging the fart, after the seat detecting sensor 36 detects that the subject is seated on the toilet seat, when the difference between the detected value of the odor gas sensor 26 and the standard value is detected, the predetermined value or more is exceeded. In the case where the rate of change sharply rises, it can be judged that the behavior of discharging the fart is being performed. In addition, the period from the time when the above-described difference is sharply increased to the time when the detected value of the odor gas sensor 26 returns to the standard value again can be used as the period for discharging the fart. In addition, in order to detect the behavior of the fart more correctly, as long as the detected data of the odor gas sensor 26 is detected to rise sharply at a rate of change above a predetermined value, the water amount sensor detects that no stool is discharged in the barrel Just in the middle. Fig. 22 is a view showing a correction chart of fart. As shown in the figure, on the correction chart of the fart, you can make such a setting in the fart. When the amount of gas (the amount of defecation gas detected by the odor gas sensor) is small, the correction value is 1, and as the amount of gas in the fart increases, the correction value also rises.

In addition, in the case of a large amount of stools in each excretion behavior, the amount of defecation gas is also large, and a more accurate analysis of the physical condition can be performed, but in the case where the amount of defecation is small, the defecation gas is The amount is also small, and the accuracy of the physical condition analysis will decrease. Therefore, the data analysis device 60 corrects the reliability by referring to the stool amount correction value map and based on the amount of effort in each excretion behavior. In addition, the amount of stool can be evaluated, for example, by a water amount sensor (a convenient amount detecting device) that detects a change in the amount of water detected by the defecation urination detecting sensor 38. Fig. 23 is a view showing a graph of the stool amount correction value. As shown in the figure, when the amount of stool is below a predetermined value, the amount of defecation gas at the same time as the amount of stool is also very small, and it cannot be detected as a system that cannot be correctly analyzed. Then, in the case where the amount of stool exceeds a predetermined value, as the large variable increases, the correction value starts from a value less than one, and the value exceeding one increases gradually. In addition, the amount of stool is judged based on each excretion behavior, so the stool amount correction value is a partial correction value.

In addition, for example, when the stool is in a squat state, the sensor cannot sufficiently detect the defecation gas because the discharge time is short. In addition, after the discharged stool floats on the water surface, the defecation gas is released, which reduces the detection accuracy of the defecation gas. Further, in the case where the stool is in the squat state, a large amount of acetic acid gas as a defecation gas which is not present during normal stool is discharged, and therefore, the physical condition cannot be detected based on the amount of the short-chain fatty acid gas. Therefore, with reference to the stool type correction chart, the squat determination device which is a built-in program of the data analysis device 60 is based on each excretion behavior. The stool type is corrected for credibility. For the stool type, the CCD of the defecation urination detecting sensor 38 as the stool state detecting means, or the microwave sensor can be used, and detection can be performed based on the detection results of these. Alternatively, since an extremely large amount of acetic acid gas is emitted when the squat is blown, the sputum can also be judged based on the detection data of the acetic acid gas. In addition, the floating of the stool can be detected by a CCD provided in the barrel as a floating detecting device, or a microwave sensor. Fig. 24 is a view showing a stool type correction chart. As shown in the figure, the squat determination device sets the system to be undetectable (correction value 0) when the subject is suffering from sputum, and sets the correction value in the excretion behavior after the detection is that the snoring is detected. A value less than 1, and the correction value is set to 1 when normal stool is detected. In addition, since the stool type is judged based on each excretion behavior, the stool type correction value is a partial correction value. In this way, when the squat determination device determines that the subject is suffering from a sputum, the detection data is not used (undetectable), or the weight of the detection data is lowered (the correction value is set to a value less than one).

In addition, usually, the degree of defecation of a healthy person is once a day. On the other hand, if the gastrointestinal state deteriorates due to food poisoning, etc., there will be multiple bowel movements within one 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 is reduced due to constipation, the defecation gas is also increased due to the increase in the generation time of the odor gas component and the increase in the amount of stool. When the interval between defecation times is too large, the accuracy of the analysis of the physical condition is lowered. Therefore, referring to the defecation interval correction chart, and based on the defecation interval, the data analysis device 60 corrects the reliability. In addition, it can be based on a data analysis device The defecation interval is determined by the 60th day of the last defecation stored and the defecation history information input in the detection start preparation step S2. Fig. 25 is a view showing a chart of correction of the stool interval. As shown in the figure, when the defecation interval is very short, the correction value is set to a value much lower than 1, and the correction value is set to 1 when the defecation interval is 1 day, and the defecation interval is 2 In the case of the day degree, the correction value is set to a value lower than 1, and when the defecation interval is 4 days, the correction value is set to a value much lower than 1. In addition, the defecation interval correction value is corrected for the whole.

When the body condition is judged based on the defecation gas, for example, in the case where the gastrointestinal state is deteriorated due to overeating of the previous day, the physical condition is judged to be more serious than the normal physical condition. Therefore, due to daily life, the analysis of physical condition will fluctuate. Therefore, for example, when the physical condition detection system performs the physical condition analysis at the start time of the physical condition detection system, the days when the physical condition is not good due to the occasional overeating are superimposed, and even if displayed on the history, only the representation is displayed. The analysis results of poor physical condition have caused the medical institutions to fail to correctly judge the disease. Therefore, the reference accumulation amount correction map corrects the reliability based on the number of pieces of past detection data stored by the subject side device. Fig. 26 is a view showing a data accumulation amount correction chart. As shown in the figure, if the number of accumulated data is less than 5 times, it is set to be impossible to diagnose (correction value 0), and if the number of accumulated data is 5 times but less than 10 times, the correction value is set to less than 1 Very low correction value, in the case where the accumulated data number is 10 times but less than 30 times, the correction value is set to a low value of less than 1, and is accumulated. When the number of data is 30 times, the correction value is set to 1. The subject side device of the present embodiment is not a device for diagnosing cancer, and is intended to cause the subject to recognize that the risk of cancer increases as the physical condition changes, thereby promoting the improvement of life. Therefore, the value of the present device is not limited to the detection accuracy of one time, but is due to the changed detection history, and it is desirable to perform such correction processing without increasing unnecessary psychological burden.

If the screening program 72 provided in the duct 18a is blocked, the amount of air sucked into the duct 18a is lowered. As a result, when the amount of gas sent to the odor gas sensor 26 and the hydrogen gas sensor 24 changes, the detection data of the odor gas sensor 26 and the hydrogen gas sensor 24 also change due to the air volume. . Further, if the gas velocity sent to the odor gas sensor 26 and the hydrogen gas sensor 24 is too fast, the contact time between the gas and the sensor is too short, and the detection portion of the sensor cannot sufficiently react. Therefore, it is preferable that the air volume sent to the odor gas sensor 26 and the hydrogen gas sensor 24 is kept constant. Therefore, with reference to the air volume correction map, the data analysis device 60 corrects the reliability based on the air volume (wind speed) sent to the odor gas sensor 26 and the hydrogen gas sensor 24. Further, the air volume of the gas can be estimated based on, for example, the current and voltage of the suction fan 18c provided in the deodorizing device. Fig. 27 is a view showing a flow rate correction map. As shown in the figure, in the air volume correction chart, if the air volume is less than the lower limit value that can be detected and the upper limit value that can be detected, the system cannot detect (correction value 0), and the air volume is in the most suitable range. In the middle, the correction value is set to a value larger than 1, and the correction value is set to a value close to 1 in the range that can be detected. In addition, in the present embodiment, the wind caused by the blockage The effect of the amount reduction is greater than the sensitivity of the sensor when the air volume is large. Therefore, in the range that can be detected, the correction value of the range where the air volume is higher than the most suitable range is set higher. The correction value of the range where the air volume is lower than the most suitable range is set lower. In addition, since the air volume during the detection does not largely change, the air volume correction is corrected as a whole.

The defecation gas contains CO _{2 which} is a healthy gas like hydrogen. Therefore, in the case where the CO ₂ gas sensor detects a large amount of CO ₂ , the sensor device can detect the defecation gas more surely. . Therefore, the data analysis device 60 corrects the reliability based on the CO ₂ correction chart and based on the detection data of the CO ₂ detected by the carbon dioxide sensor 28. Figure 28 is a diagram showing a CO ₂ correction chart. As shown in the figure, in the CO ₂ correction chart, when the detection amount of CO ₂ is smaller than the predetermined value, the correction value is set to 1, and when the detection amount of CO ₂ is equal to or greater than the predetermined value, the correction is performed as the value is increased. The value also increases. In addition, since the correction value of CO ₂ is calculated corresponding to each excretion behavior, it is a partial correction. As described above, in the present embodiment, a CO ₂ gas amount correction based on the detected hydrogen gas, the use of hydrogen gas and a CO ₂ gas health assessment based gas.

In addition, 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 H ₂ correction chart may be used instead of the CO ₂ correction chart, and in the H ₂ correction chart, the hydrogen gas sensing is performed. The higher the detected value of the device 24, the higher the correction value.

The defecation gas contains methane which is a healthy gas like hydrogen. Therefore, for example, it is set in the duct 18a of the deodorizing device. A methane gas sensor that strongly reacts with methane gas. When the methane gas sensor detects a large amount of methane, the defecation gas is released in a large amount. Therefore, the data analysis device 60 corrects the reliability by referring to the methane gas correction map and based on the methane gas detection amount detected by the methane gas sensor. Figure 29 is a diagram showing a methane gas correction chart. As shown in the figure, in the methane gas correction chart, when the detection amount of methane gas is smaller than a predetermined value, the correction value is set to 1, and when the detection amount of methane gas is equal to or greater than a predetermined value, methane gas is used. The increase is also increased. In addition, since the correction value of methane gas is calculated corresponding to each discharge behavior, it is a partial correction value.

Further, in the present embodiment, when the detection value of CO ₂ and methane is high, the reliability is corrected to be high. However, the present invention is not limited thereto, and when the detection value of CO ₂ and methane is high, The detected value of the hydrogen gas can be corrected to a high level.

In the case where there are cancer cells in the intestine, the defecation gas contains not only an odor gas but also hydrogen sulfide gas. Therefore, for example, a hydrogen sulfide gas sensor capable of strongly reacting hydrogen sulfide gas is disposed in the pipe 18a of the deodorizing device, and the reliability is corrected based on the detection data of the hydrogen sulfide gas detected by the hydrogen sulfide gas sensor. degree. Fig. 30 is a view showing a hydrogen sulfide gas correction chart. As shown in the figure, in the hydrogen sulfide gas correction chart, when the detection amount of the hydrogen sulfide gas is smaller than a predetermined value, the correction value is set to 1, and when the detection amount of the hydrogen sulfide gas is equal to or greater than a predetermined value, As the hydrogen sulfide gas increases, the correction value also increases. In addition, because the corrected value of hydrogen sulfide gas is calculated corresponding to each discharge behavior, Therefore, it is a partial correction value. The reliability is calculated using some or all of the correction charts described above.

Next, in the example described with reference to FIG. 9, the detailed description of the method of estimating the amount of gas is omitted, and therefore, it will be described here.

As the odor gas sensor 26 for detecting an odor gas, a semiconductor sensor or a solid electrolyte type sensor is used. A gas sensor such as a semiconductor sensor or a solid electrolyte type sensor or a hydrogen gas sensor reacts not only to an odorous gas but also to an aromatic agent or an ethanol contained in a sterilizing cleaning cloth.

That is, even if the subject is not in the toilet, environmental detection noise is included in the detection data of the gas sensor due to, for example, the influence of the residual stool attached to the body of the fragrance or the toilet. In addition, the influence of the residual stool attached to the fragrance and the bowl of the toilet does not change greatly with time.

In addition, after the subject enters the toilet, the gas sensor detects the body odor of the subject, or the odor gas component attached to the body or clothing of the subject, such as perfume or hair styling used. The detected value will rise slowly, and after the subject is seated, because the upper part of the barrel is covered by the subject or the clothes, the detected value detected by the gas sensor tends to be stable or rises slowly.

In addition, it is assumed that the subject cleans the toilet seat with a sterilizing cleaning cloth, so that the amount of gas detected by the semiconductor gas sensor increases sharply at the moment after the sterilizing cleaning cloth is used, but when the detected person falls After the seat, that is, shortly after the use of the sterilizing cleaning cloth, the effect of the sterilizing cleaning cloth no longer causes an increase in the detected value detected by the gas sensor.

That is, after the subject is seated, the detected value of the gas sensor gradually increases due to the influence of the odor gas adhering to the subject, but does not increase sharply.

On the other hand, after the subject starts the excretion behavior, the gas sensor reacts with the odor gas and the hydrogen gas contained in the defecation gas at the time when the excretion behavior is performed, and the detection value of the gas sensor is sharp. Increase, decrease after reaching the peak.

Therefore, the inventors of the present invention considered that the detected value when the detected value of the gas sensor is not sharply increased after the subject is seated on the toilet seat is regarded as a standard value by the sharpness of the detected value than the standard value. When the detection is increased, the odor gas and the hydrogen gas contained in the defecation gas can be detected.

Therefore, in the present embodiment, as described with reference to Fig. 9, at time t2, the seating detection sensor 36 detects that the subject has been seated on the toilet seat 4, and the data analysis device 60 will be after time t2. And the detection data of the gas sensor during the non-excretion behavior before the time t5 at which the excretion behavior starts is set as a standard value. Next, the data analysis device 60 sets the rate of change of the difference between the detected value of the gas sensor and the standard value at time t5 to a positive predetermined value or more, and sets the start time of the excretion behavior. Then, the data analysis device 60 integrates the difference between the detected value of the gas sensor and the standard value at the time of performing the excretion behavior from the start time point to the end time point of the excretion behavior (ie, The area of the portion where the amount of gas in the excretion behavior is larger than the standard value is obtained as the estimated amount of defecation gas. The end time of the excretion behavior may be set to a time point at which the detected value of the gas sensor is restored to the standard value again, or may be set as a difference between the detected value of the gas sensor and the standard value after the start time point. The rate of change is changed from positive to negative.

Further, similarly to the odor gas sensor 26, the hydrogen gas sensor 24 and the carbon dioxide sensor 28 may be affected by odor detection noise (odor gas detection noise) other than the defecation gas. Therefore, when estimating the gas amount of the hydrogen gas and the carbon dioxide gas based on the detection data of the hydrogen gas sensor 24 and the carbon dioxide sensor 28, the same method as in estimating the gas amount of the odor gas can be used.

Further, the method of estimating the amount of gas is not limited to the above method. Hereinafter, a method of estimating the amount of gas in the body information detecting system of the second embodiment will be described. The second embodiment differs from the first embodiment only in the method of estimating the amount of gas.

In the system of the present embodiment, in the present embodiment, as in the first embodiment, the odor gas sensor 26 for detecting the odor gas is a semiconductor gas sensor or a solid electrolyte type sensor. The semiconductor gas sensor or the solid electrolyte type sensor detects the amount of gas by detecting the reaction of the heated detecting portion, and thus the sensitivity is low. In addition, as with the semiconductor gas sensor, the sensitivity of the hydrogen gas sensor 24 is also low. In the case of using such a less sensitive gas sensor, the following problems occur. In addition, the following problems are not unique to semiconductor gas sensors, and solid electrolyte sensors and hydrogen gas sensors also exist. Kind of problem.

For example, as shown in Fig. 31, a semiconductor gas sensor is used as the odor gas feeling under the conditions S1, S2, and S3 in which the total amount of gas discharged from the defecation gas is constant but the discharge time and the discharge amount per unit time are different. The detector 26 detects the odorous gas. Fig. 32 is a view showing the waveform of the detection data of the gas sensor when the discharge time and the discharge amount per unit time are changed. Fig. 33 shows the amount of gas calculated based on the waveform of the detection data of the gas sensor. Further, S1', S2', and S3' in Figs. 32 and 33 correspond to S1, S2, and S3 in Fig. 31, respectively.

As shown in Fig. 32, even if the total amount of gas discharged from the defecation gas is constant, when the discharge time is different, the waveform of the gas discharge amount (detection data) needs to pass the same amount of time according to the time constant of the gas sensor. Convergence to a certain value. Therefore, the inventors of the present invention have noticed the slope of the waveform of the gas discharge amount when the gas is exhausted. Fig. 34 is a view showing an enlarged display of the initial portion of the detected data waveform of the gas sensor shown in Fig. 32 on the time axis. As shown in the figure, when the discharge amount (discharge concentration) per unit time is different, the slope from the start of discharge to the peak value is different from the time required to reach the peak. Further, the larger the discharge amount per unit time (discharge concentration), the larger the slope until reaching the peak value, and the longer the gas discharge time is, the longer the time required to reach the peak value. In addition, Fig. 35 shows the relationship between the discharge amount per unit time (discharge density) and the slope of the detected data waveform detected by the sensor when it rises. As shown in the figure, it can be said that the discharge amount per unit time (discharge concentration) and the detected data waveform detected by the sensor are approximately proportional to the slope when rising.

The inventors have found that the slope of the detected data waveform of the semiconductor gas sensor described above corresponds to the discharge amount (discharge concentration) of the exhaust gas per unit time, and the detection data waveform of the semiconductor gas sensor needs to reach a peak value. Based on this finding, the inventors decided to estimate the amount of gas based on the product of the slope of the detected data waveform of the semiconductor gas sensor and the time required to reach the peak value (the area of the gas sensor detection data waveform). Further, Fig. 36 shows the slope of the detected data waveform and the time required to reach the peak value based on the semiconductor gas sensor under the conditions S1, S2, and S3 in which the discharge time and the discharge amount per unit time (discharge density) are different. The amount of gas estimated by the product (the gas sensor detects the data waveform area). As shown in the figure, the gas amounts S1", S2", and S3" estimated based on the product of the slope of the gas amount waveform and the time required to reach the peak value are the same amount, and thus the slope of the waveform based on the gas amount is known. The time required to reach the peak can accurately estimate the amount of gas.

Therefore, in the present embodiment, similarly to the above-described first embodiment, the odor gas sensor 26 is used after the time when the seat detecting sensor 36 detects that the subject is seated and before the start of the excretion behavior. Test the data to set the standard value. Further, as shown in Fig. 10(a), the time point at which the rate of change of the difference between the detected value and the standard value detected by the odor gas sensor 26 exceeds the preset start threshold is set as the estimated bowel movement. The starting point of the amount of gas (ie, the starting point of the excretion behavior). Next, as shown in Fig. 10(a), the rate of change of the difference between the detected value and the standard value detected by the odor gas sensor 26 becomes a negative time point (i.e., odor gas sensing) The time at which the peak of the detected data of the device 26 Point) is set to the end time point at which the amount of defecation gas is estimated (that is, the end time point of the excretion behavior).

Next, the data analysis device 60 calculates the rate of change of the difference between the detected data and the standard value from the start time point to the end time point of the excretion behavior. Further, the data analysis device 60 calculates the defecation gas discharge time from the start time point to the end time point of the excretion behavior. Then, the data analysis device 60 integrates the rate of change of the difference between the detection data and the standard value of the excretion behavior from the start time point to the end time point on the defecation gas discharge time, and estimates the integral value as the gas amount. Further, similarly to this, the hydrogen gas amount estimation may be performed based on the detection data of the hydrogen gas sensor 24, and the carbon dioxide gas amount estimation may be performed based on the detection data of the carbon dioxide sensor 28. According to the gas amount estimation method described above, the influence of the time constant of the gas sensor can be eliminated, and the amount of defecation gas can be accurately estimated.

Further, the inventors have studied the relationship between the discharge amount per unit time of the defecation gas and the discharge time, and found that the relationship between the discharge amount and the discharge time is small in the difference between different people. That is, when the discharge amount per unit time of the defecation gas is large, the discharge time is a short certain time regardless of the subject, and when the discharge amount per unit time of the defecation gas is small, regardless of the subject Who is the discharge time is a certain period of time. Therefore, the inventors have estimated that the discharge amount per unit time of the odor gas in the defecation gas (the rate of change of the detected value detected by the odor gas sensor 26) can estimate the defecation gas (odor gas). Discharge time. In addition, similarly, units based on hydrogen gas and carbon dioxide The discharge amount of time (the rate of change of the detected value detected by the hydrogen gas sensor 24 and the carbon dioxide sensor 28) can estimate the discharge time of the defecation gas (hydrogen gas and carbon dioxide). Further, in the present embodiment, the area is estimated to obtain a correlation between the amount of the healthy gas and the amount of the odor gas, and in fact, the concentration of the healthy gas and the concentration of the odor gas are also correlated, and accordingly, The same result, therefore, can also be constructed in the present invention to obtain the concentration using the slope of the detected value of each sensor. In this case, it is not necessary to estimate the area, which makes the detection easier.

Hereinafter, a gas amount estimation method in the body information detecting system according to the third embodiment of the above-described findings will be described. In the third embodiment, the gas amount estimation method differs from the first and second embodiments. In addition to setting the start threshold of the rate of change of the difference described in the above embodiment, the data analysis device 60 also sets the rate of change-discharge period data, which is the rate of change of the difference and the time of discharge of the gas. Information on the correspondence between the two.

The standard value is set based on the detection data of the odor gas sensor 26 after the time when the seat detecting sensor 36 detects the seat of the subject and before the start of the draining behavior. The time point at which the rate of change of the difference between the detected value and the standard value detected by the odor gas sensor 26 exceeds a preset start threshold is set to a start time point at which the amount of defecation gas is estimated (ie, excretion behavior) The starting point of time). Then, the data analysis device 60 refers to the change rate-discharge period data, and obtains the discharge period data corresponding to the rate of change of the difference between the detected value and the standard value at the start time point. Thereafter, the data analysis device 60 obtains the integral of the change rate of the difference between the detection data and the standard value at the start time of the excretion behavior at the discharge time, and estimates the integrated value as the gas amount. Further, similarly to this, the hydrogen gas amount estimation may be performed based on the detection data of the hydrogen gas sensor 24, and the carbon dioxide gas amount estimation may be performed based on the detection data of the carbon dioxide sensor 28. According to the gas amount estimation method described above, the influence of the time constant of the gas sensor can be eliminated, and the amount of defecation gas can be accurately estimated. Further, in the gas amount estimating method of each of the above-described embodiments, the case where the semiconductor gas sensor is used as the odor gas sensor 26 has been described, but the semiconductor electrolyte is replaced by the solid electrolyte type sensor. In the case of a sensor, the gas amount can also be estimated. Further, in the above-described embodiment, the data analysis device 60 obtains the rate of change of the difference between the detected value at the start time of the excretion behavior and the standard value, and refers to the rate of change-discharge period data to obtain the start time of the excretion behavior. The discharge period data corresponding to the rate of change between the detected value of the point and the standard value is based on the rate of change and the amount of gas estimated during the discharge period, but the present invention is not limited thereto. For example, the rate-gas amount data in which the rate of change of the difference is correlated with the amount of gas may be stored in advance, the rate of change of the difference may be obtained, and the amount of gas may be directly estimated by referring to the rate of change-gas amount data.

Further, the body information detecting system according to the first embodiment described with reference to Fig. 1 is configured such that the detecting device 6 is attached to the inside of the toilet seat 4 of the flush toilet 2 provided in the restroom R, and the above description has been made. . However, the detecting device of the body information detecting system of the present invention does not have to be installed inside the toilet seat.

(a) of FIG. 37 is a view showing a state in which the subject-side device of the body information detecting system of the fourth embodiment is attached to the flush toilet 2 installed in the toilet, and (b) of the figure shows the A perspective view of the detecting device of the subject side device shown in (a) of the drawing. Further, in the second embodiment, only the configuration of the subject side device is different from that of the fourth embodiment. As shown in Fig. 37 (a), the body information detecting system 101 of the present embodiment has the same configuration as that of the first embodiment, and only the detecting device 106 of the subject side device 110 has a different configuration. The detecting device 106 of the present embodiment is separate from the toilet seat 104.

As shown in Fig. 37(b), the detecting device 106 includes a device main body 180, a duct 118a, and a power supply line 182, wherein the duct 118a is mounted on the upper surface of the apparatus main body 180 in a laterally extending manner, and the tip end portion thereof is bent downward. The power cord 182 is connected to the device body 180. As shown in Fig. 37 (a), the detecting device 106 is hung on the side wall of the tub of the flush toilet 2 with the tip end portion of the duct 118a, and the tip end portion of the duct 118a is fixed in the state of the tub body.

Similarly to the first embodiment, the apparatus main body 180 includes a hydrogen gas sensor, an odor gas sensor, a carbon dioxide sensor, a humidity sensor, a temperature sensor, an entrance detecting sensor, and a seating detecting sensor. Defecation urination detection sensor, suction device, sensor heater and transceiver. The gas sucked by the duct 118a is deodorized and then discharged through a deodorizing air outlet provided on the bottom surface of the apparatus main body 180. Inside the duct 118a, a hydrogen gas sensor, an odor gas sensor, a carbon dioxide sensor, a humidity sensor, a temperature sensor, a sensor heater, and a fan are disposed. turn off Since the arrangement of the sensors in the duct 118a is the same as that of the first embodiment, the description thereof is omitted here. According to such a configuration, with the detecting device 106 of the present embodiment, the odor gas, the hydrogen gas, and the carbon dioxide gas contained in the defecation gas can be obtained by the odor gas sensor, the hydrogen gas sensor, and the carbon dioxide sensor. The corresponding test data.

Further, the toilet seat 104 to be used together with the detecting device 106 of the present embodiment preferably has a toilet seat cover opening and closing device, a nozzle driving device, a nozzle cleaning device, a toilet cleaning device, and a toilet sterilization device, and A toilet seat that can communicate with the detection device 106 and has a cleaning function. By using such a toilet seat and the detecting device 106 at the same time, various cleaning and sterilization operations can be performed with the detection of the odor gas.

Further, in the first embodiment, as shown in FIG. 3, in the gas detecting device 20, the hydrogen gas sensor 24 is provided on the upstream side of the screening program 78, but this need not necessarily be the case. structure. Fig. 38 is a view showing the configuration of a gas detecting device in the body information detecting system of the fifth embodiment. Further, in the fifth embodiment, only the configuration of the gas detecting device is different from that of the first embodiment. As shown in the figure, in the gas detecting device 120 of the present embodiment, the arrangement of the hydrogen gas sensor 24 is different from that of the embodiment shown in Fig. 3. In the present embodiment, the hydrogen gas sensor 24 is provided upstream of the deodorizing screening program 78 in the intake passage 18b. According to such a configuration, even in the case where a sensor that reacts not only to hydrogen but also to the odor gas is used as the hydrogen gas sensor 24, the odor can be eliminated from the output of the hydrogen gas sensor 24. The influence of the taste gas.

Further, in the first embodiment, the detected value detected by the hydrogen gas sensor 24 is subtracted from the detected value detected by the odor gas sensor 26, and the influence of the hydrogen gas is separated to calculate the odor. The detected value of the gas, but the present invention is not limited thereto. For example, as described below, the influence of the hydrogen gas can be separated by shifting the arrival time of the hydrogen gas and the odor gas to the odor gas sensor 26. .

Figure 39 is a view showing the configuration of a gas detecting device in a sixth embodiment of the present invention. In the first embodiment of the present invention, the hydrogen gas and the odor gas are directly detected by the respective gas sensors. However, in the present embodiment, the gas components are separated by the analysis column, and based on this, a single gas is sensed. In addition to detecting hydrogen gas and odor gas, the device also detects short-chain fatty acid gases. Further, in the sixth embodiment, only the configuration of the gas detecting device is different from that of the first embodiment. As shown in the figure, in the present embodiment, a sub-passage 283b branched from the main passage 283a of the intake passage 18b of the duct 18a is provided. Further, in the first embodiment, the hydrogen gas sensor and the odor gas sensor are separately provided, but in the configuration of the embodiment, the hydrogen gas, the odor gas, and the odor gas are detected by one semiconductor gas sensor. Short chain fatty acid gas.

Here, the principle of the body condition detection of the body information detecting system of the present embodiment will be described.

As described above, the short-chain fatty acid gas is a gas which is generated only when the pH in the intestine is low and the intestinal environment is good, and the detection of the gas can reliably determine that the intestinal environment is good. In this way, in a state in which the intestinal environment is good, pathogenic bacteria that cause harmful components such as colorectal cancer are not produced. Because it is easy to survive, it can be said that a subject having a low pH and a good intestinal environment is resistant to a major disease such as colorectal cancer, that is, the immunity is in a high state. On the other hand, in the intestinal environment where many pathogenic bacteria are present, the harmful components produced by these pathogenic bacteria in the large intestine are likely to induce diseases such as colorectal cancer, and thus the risk of major diseases is high.

Here, in the defecation gas discharged during defecation, in addition to hydrogen sulfide and methyl mercaptan, it also contains nitrogen, oxygen, argon, water vapor, carbon dioxide, hydrogen, methane, acetic acid, trimethylamine, ammonia, propionic acid, and butyl. Acid, dimethyl disulfide, methyl trisulfide, and the like. As described above, short-chain fatty acids produced by probiotic bacteria in the intestine include acetic acid, propionic acid, butyric acid, and the like. Most of these short-chain fatty acids are absorbed by the large intestine, and only a few short-chain fatty acids remain in the stool. Here, the inventors have found that a part of a small amount of short-chain fatty acids remaining without being absorbed is vaporized and contained in the defecation gas. In the body information detecting system 1 of the present embodiment, a very small amount of vaporized short-chain fatty acid contained in the defecation gas is successfully detected, and the intestinal health state of the subject and the colorectal disease are successfully based on the test. The immunity was judged. In the present embodiment, as will be described later, a part of the defecation gas is introduced into a tube called an analytical column, and acetic acid gas and propionic acid gas as short-chain fatty acids are used from the other gas components by analyzing the time difference of the column. Separated and detected in the gas.

As described above, acetic acid which is a short-chain fatty acid exists in the defecation gas when the body condition is good, but the inventors have found that when the subject suffers from sputum, the amount of acetic acid discharged is extremely increased. This is because the subject is sent to the large intestine if he or she suffers from convulsions. The time during which the digestate stays in the large intestine becomes very short, and the short-chain fatty acid such as acetic acid contained in the digest is not substantially absorbed, but is excreted together with the stool. Because the increase in short-chain fatty acids caused by the sputum in the subject is such an extremely large value that it will not occur in the absence of sputum, it can be clearly combined with the body based on the test data. The short-chain fatty acid gas discharged when it is in good condition is distinguished. In other words, based on the amount of the short-chain fatty acid gas (acetic acid gas) contained in the detected defecation gas, it is possible to detect whether or not the subject is suffering from sputum.

In the present embodiment, as shown in Fig. 39, in the same manner as in the first embodiment, the intake passage 18b is provided with a screening program 72, a deodorizing screening program 78 located downstream of the screening program 72, and a suction fan 18c. The sub passage 283 branches off on the downstream side of the screening program 72. The screening program 72 is a screening program that does not have a deodorizing function, and passes odor gas and hydrogen gas to prevent the passage of foreign matter such as urine or detergent. In the same manner as in the first embodiment, the deodorizing screening program 78 is a catalyst that adsorbs a gas component such as an odor gas.

The defecation gas in the tub 2a of the toilet is sucked into the intake passage 18b by a suction fan 18c at a constant flow rate. The defecation gas sucked into the inhalation passage 18b passes through the screening program 72, and foreign matter such as urine and detergent is removed, and the gas component such as odor gas is removed by the deodorizing screening program 78, and then returned to the toilet. Inside the barrel 2a.

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

The flow path switching valve 284 is opened only for a part of the time (very short time) in the excretion behavior, and is used to generate a part of the defecation gas flowing through the inhalation passage 18b (a part of the time of the excretion behavior of the subject) The amount of defecation gas is introduced into the valve in the secondary passage 283b. The flow path switching valve 284 is provided at the most upstream of the sub passage 283b.

The analysis column 286 is provided on the downstream side of the flow path switching valve 284, and is constituted by an elongated pipe and, for example, a fine fiber material or the like filled in the pipe. The analytical column 286 is a mechanism that utilizes the principle of gas chromatography to cause a difference in the passage time of the gas depending on the size (molecular weight) of the molecule.

On the upstream side of the semiconductor gas sensor 288, a sensor heater 54 is provided for heating the detecting portion of the semiconductor gas sensor 288 to a predetermined temperature, and removing the adhesion to the semiconductor gas sensor 288 Odorous gas component.

The flow rate switching valve 284 causes the defecation gas flowing through the inhalation passage 18b to flow into the sub-channel 283b after a small amount of defecation gas flowing through the screening program 72. Thereafter, after the pump 290 is driven, according to the principle of gas chromatography, the hydrogen gas and the odor gas contained in the defecation gas pass through the analytical column 286 at different times depending on the molecular weight, and reach the semiconductor gas sensor 288. That is, hydrogen gas having a small molecular weight easily passes through the analytical column 286, and reaches the semiconductor gas sensor 288 in a short time, and the odor gas having a large molecular weight does not easily pass through the analytical column 286, and it takes a long time to reach the semiconductor gas sensor. 288. Further, the pump 290 is structured to draw the defecation gas at a constant flow rate.

Figure 40 is a view showing the gas detecting device shown in Figure 39. A diagram of the detected data waveform detected by the semiconductor gas sensor. As shown in the figure, with the configuration of the gas detecting device 220 of the present embodiment, the semiconductor gas sensor 288 reacts with a short-chain fatty acid gas, a hydrogen gas, and an odor gas at different times. In particular, when the excretion behavior is performed in a short time, the defecation gas containing the hydrogen gas and the odor gas is discharged only in a short time. As such, by disposing the analytical column 286 upstream of the semiconductor gas sensor 288, short-chain fatty acid gas, hydrogen gas, and odor gas can be caused to reach the semiconductor gas sensor 288 when the defecation gas is discharged in a short time. The time is shifted so that a semiconductor gas sensor 288 can detect the amount of gas of the short-chain fatty acid gas, the amount of gas of hydrogen, and the amount of gas of the odorous gas. This is also based on the technical findings discovered by the inventors that it is not necessary to detect the total amount of gas associated with cancer-related methyl mercaptan, but rather to use health in addition to the amount of gas according to short-chain fatty acid gases. A method for judging the physical condition by correlating a gas-like gas with an odor gas, in which case gas detection is performed only for a specific period. The use of a redox sensor can make the price lower, but it is difficult to separate a large amount of hydrogen contained in the defecation gas. On the other hand, according to the present embodiment, only a small amount of detection of a specific period is performed, so that hydrogen gas can be easily separated, and practicality can be realized by using a sensor having a very low price.

Further, in the present embodiment, the analysis column 286 shifts the time during which the short-chain fatty acid gas, the hydrogen gas, and the odor gas reach the semiconductor gas sensor 288, and of course, the methane and the odor gas contained in the defecation gas can be reached. The arrival time of the semiconductor gas sensor is staggered. Thereby, it is possible to separate not only hydrogen from the detection data detected by the semiconductor gas sensor The effect of gas can also separate the effects of methane.

Next, the physical condition display chart in the present embodiment will be described with reference to Fig. 41. In the screen shown in Fig. 5 of the first embodiment, there is a "detailed screen" button, and the graph displayed by pressing the button is the physical condition display map.

As shown in Fig. 41, a physical condition display chart is displayed on the left side of the screen. The physical condition display chart is a graph in which the vertical axis indicates an index related to the amount of gas of the odor gas (showing as a poorly-conditioned gas) as the first index, and the horizontal axis indicates the health index as the second index. An indicator of the amount of gas in the gas. Further, on the right side of the display screen, a map of the disease immunity estimated based on the detection data of the short-chain fatty acid gas as the third index is also displayed. That is, the degree of immunity of the subject obtained by the detection data of the short-chain fatty acid gas is marked on the vertical display of the immunity bar graph. Further, the first index is based on the first detection data detected by the gas detecting device 220 and is related to the amount of the odor gas. The second index is based on the second detection data detected by the gas detecting device 220 and is related to the amount of hydrogen gas as a healthy gas. Further, the third index is based on the third detection data detected by the gas detecting device 220 and is related to the amount of the short-chain fatty acid gas. Further, as the second index, the amount of gas of carbon dioxide gas or methane gas as a healthy gas may be used. In the display device 68 of the remote controller 8, on the physical condition display chart having the vertical axis and the horizontal axis as described above, the detection result of the defecation gas of the subject is displayed by the marked points (marked points indicated by time) over time. .

Next, referring to Fig. 42, the seventh embodiment of the present invention The body information detection system of the form is described.

In the sixth embodiment, based on the detected data of the detected short-chain fatty acid gas, the immunity of the subject is displayed on the immunological display bar graph on the display device, based on the detected odor gas and hydrogen gas. The test data is displayed on the physical condition display chart to show the mark indicating the physical condition. This embodiment differs from the above-described sixth embodiment only in that the position of the marker displayed on the physical condition display chart is corrected based on the detection data of the short-chain fatty acid gas. Therefore, only differences from the sixth embodiment will be described here, and the description of the same configuration will be omitted.

Fig. 42(a) is a diagram showing an example of correction of a marker point displayed on a physical condition display chart. Fig. 42 (b) is a view showing an example of the correction amount based on the detected amount of acetic acid gas as a short-chain fatty acid.

As described in the sixth embodiment, on the physical condition display chart, the marker points of the detection data detected based on the current defecation behavior are displayed, and the marker points based on the past detection data are also displayed. Then, based on the reliability of the current detection, the display position of the current marker point is displayed after the position correction is performed so as to approach the gravity center position G of the past data (FIG. 17). That is, in Fig. 42(a), when the mark point of the original material based on the current test data is "1", the display position of the mark point is corrected to approach the gravity center position G of the past data to " Displayed at the position of 1'" (actually no "1" mark is displayed). Further, the lower the reliability of the current detection, the more the position of the marker point "1" is greatly corrected, and the closer to the gravity center position G (the marker point "1'" moves toward the vicinity of the gravity center position G). On the other hand, in the sixth embodiment, in addition to the physical condition display chart, the immunity of the subject is displayed on the immunity display bar graph based on the detection data of the short-chain fatty acid gas.

On the other hand, in the present embodiment, the position of the marker point "1'" corrected based on the reliability is further corrected based on the detection data of the short-chain fatty acid gas. That is, a short-chain fatty acid gas such as an acetic acid gas is a gas produced by a probiotic such as bifidobacteria in the large intestine, and such a gas hardly occurs in a state in which the intestinal tract is in a state of inferiority and the pathogenic bacteria occupy a dominant position. Therefore, in the current detection, even if the detection data of the odor gas and the hydrogen gas show that the physical condition is not good, it is possible to determine that the intestinal state is not necessarily bad as long as the acetic acid gas or the like is discharged to a certain extent. Therefore, in the present embodiment, the correction amount of the current detection data (the correction amount between the marker point "1" and "1'") is further improved to the physical condition based on the detection data of the acetic acid gas (health one) The side is corrected in the right direction on Fig. 42 (a).

Fig. 42(b) is a view showing an example of the correction amount based on the amount of acetic acid gas in the defecation gas.

For example, when the detected amount of acetic acid gas satisfies the condition of "20%" correction, the position of the marker point "1'" is moved to the healthy side (the right side in (a) of Fig. 41) to "1". The marker point is displayed at the position of ''" (actually, "1", "1'" is not displayed in the graph), where the distance moved is 20% of the distance between the marker points "1" → "1" . Further, as shown in (b) of Fig. 41, the larger the amount of acetic acid gas detected, the larger the amount of correction of the marked point toward the healthy side (the side with good physical condition).
