Description

  The present invention relates to a health condition measuring apparatus that collects a combined gas when a subject defecates and discriminates the health condition of the subject.

  Conventionally, there has been a technique for detecting excretion gas (hereinafter referred to as co-occurrence gas) that is generated at the time of defecation and determining the health condition of the subject based on the detection result. For example, Patent Literature 1 includes a hydrogen gas sensor that detects hydrogen gas contained in a combined gas excreted in a bowl of a toilet bowl, and determines the intestinal state of the user based on a signal value from the hydrogen gas sensor. A technique for notifying the user is disclosed, and Patent Document 2 discloses a signal value output from a gas sensor for detecting a predetermined gas component contained in the combined gas in the atmosphere in the bowl of the toilet bowl. By having a storage unit that stores correspondence data representing correspondence with information on the intestinal bacteria balance of the user and a processing unit that extracts information on the enteric bacteria balance from the correspondence data and notifies the user A technique has been disclosed in which the intestinal state can be easily notified to the user.

  These technologies measure the concentration and composition ratio of specific components of the combined gas to determine the health status of the subject. The component status of the combined gas is not only the health status of the subject but also the suddenness of other subjects. It varies depending on various factors. Therefore, although there are parts that can be determined only by a single measurement result, it is often necessary to make a more accurate determination based on the accumulated information of the measurement data that has been continued.

  However, the measurement opportunity is limited to the time of excretion, and the number of times and the degree of freedom are generally small. Therefore, one measurement opportunity is valuable from the viewpoint of storing measurement data, and it is necessary to accumulate data without waste. There is.

  On the other hand, since the measurement of these combined gases involves excretion using a toilet, if the subject performs an operation such as leaving the toilet seat or cleaning the toilet during the measurement, or shorter than the expected measurement time There is a possibility that unforeseen circumstances associated with these excretion acts may occur, such as when the measurement is terminated in time. All of these situations change the state of the atmosphere in the bowl of the toilet bowl. In such a method for measuring a combined gas, it can be said that this is an abnormal situation that affects the measurement results.

  Hereinafter, an embodiment of the present invention will be specifically described with reference to the drawings. FIG. 1 is a perspective view showing a seated toilet having the health condition measuring apparatus according to this embodiment, and FIG. 2 is a configuration diagram showing the health condition measuring apparatus.

  First, the outline | summary of the health condition measuring apparatus 1 which concerns on this embodiment is demonstrated. The health condition measuring apparatus 1 according to the present embodiment collects the combined gas released into the toilet bowl at the time of defecation of the subject together with the atmosphere in the toilet bowl, and measures the predetermined component concentration in the combined gas. The health condition of the subject is determined, and is mounted on a seated toilet 10 as shown in FIG.

In the present embodiment, carbon dioxide (CO ₂ ) gas, which is an odorless gas, is used as the gas component to be subjected to concentration measurement, that is, the predetermined component in the combined gas discharged from the body when the subject defecates. However, hydrogen gas (H ₂ ), which is also an odorless gas, may be used, and in any case, the state in the intestine of the subject can be estimated from the measured value. That is, it is known that there is a correlation between the odorless gas (CO ₂ and H ₂ ) in the combined gas and the “number of useful bacteria”, “pH”, and “odor” that are parameters for estimating the intestinal state. Yes.

Usually, the more CO ₂ (H ₂ ), the more Bifidobacteria, lactobacilli, etc., the acidic pH, the less odor, and the better the state of intestinal health.

  As shown in the figure, the seat-type toilet 10 includes a toilet seat 13 and a toilet lid so that the casing 50 placed on the toilet body 11 on which the bowl portion 12 is formed can be raised and lowered at the opening edge of the bowl portion 12. Fourteen bases are connected in a undulating manner. Further, a local cleaning nozzle 15 is disposed in the bowl portion 12 so as to freely advance and retract.

  In addition, an operation display panel 30 for performing various operations of the seated toilet 10 and operations of the health condition measuring apparatus 1 is installed on the lateral side wall W in the room where the seated toilet 10 is installed. In the figure, reference numeral 28 denotes a display unit provided on the operation display panel 30, and 29 also denotes an operation unit. The operation unit 29 includes, for example, a measurement start button, a measurement end button for forcibly ending the measurement, a personal recognition button serving as a trigger for starting and ending the measurement of a predetermined component concentration in the combined gas assigned to each of a plurality of subjects. Is provided.

  As shown in FIG. 2, the health condition measuring apparatus 1 includes a concentration measuring unit A that measures a predetermined component concentration in a combined gas discharged from the body when a subject defecates, and a concentration output by the concentration measuring unit A. A density measurement value storage means B for storing the measurement value, and a density measurement result in any one measurement operation by a predetermined processing method based on the density measurement value stored in the density measurement value storage means B Concentration measurement value determining means C for determining a measured value; intestinal condition index value calculating means D for calculating an intestinal condition index value serving as an index representing the intestinal condition of the subject from the concentration measurement value; and the predetermined component concentration Operation of concentration measurement start detection means E for detecting the start of measurement, concentration measurement end detection means F for detecting completion of the measurement of the predetermined component concentration, and operation of various devices included in the toilet Information and Includes a motion information obtaining means H for obtaining, and the concentration measurement time storage means G for storing the time elapsed from the density measurement start time detected by said density measurement start detection means E as the density measurement time Te.

  Then, the concentration measurement value determining means C is used when the operation information acquisition means H acquires predetermined operation information during measurement of the predetermined component concentration, or when the concentration measurement end detection means F measures the predetermined component concentration. The density measurement value is determined by a processing method corresponding to the density measurement time when the end is detected.

  That is, the operation information acquisition unit H adversely affects the measurement result by changing the component concentration state of the atmosphere in the toilet bowl as a sample of the concentration measurement unit A among the operations of various devices included in the seated toilet 10. Various operations such as a warm air drying operation accompanying local cleaning, an operation in which a subject leaves the toilet seat 13, or a switch operation for performing toilet cleaning is acquired as predetermined abnormal operation information. is there.

Thus, according to the health condition measuring apparatus 1 according to the present embodiment, when measuring the concentration of the predetermined component (CO ₂ ) in the combined gas, the operation information of the various devices described above and the concentration measurement time are the predetermined time. Whether or not there is a density measurement value is taken into the element, and measurement processing corresponding to an abnormal situation of density measurement can be performed.

  That is, as described above, the health condition measuring apparatus 1 is configured such that when the operation information acquisition unit H acquires predetermined operation information during measurement of a predetermined component concentration, or the concentration measurement end detection unit F performs the predetermined measurement. At least the following two processes are employed as the concentration measurement value determination processing method performed by the concentration measurement value determination means C according to the concentration measurement time when the measurement of the component concentration measurement is detected.

First process: When the density measurement time is less than a predetermined time, measurement is performed by discarding the density measurement value as measurement failure regardless of the density measurement value stored in the density measurement value storage means B. No result.
Second processing: When the concentration measurement time is equal to or longer than the predetermined time, the maximum peak value of the concentration measurement value stored in the concentration measurement value storage means B as the measurement establishment is determined as the concentration measurement value.

In the present embodiment, the following third process is also performed.
Third processing: If there is no maximum peak value even if the concentration measurement time is equal to or longer than the predetermined time, the maximum value is set as the concentration measurement value.

  As shown in FIG. 2, the health condition measuring apparatus 1 is based on the time series data storage means J for storing the measurement result including the intestinal condition index value as time series data for each subject, and the time series data. And a fluctuation tendency calculating means K for calculating the fluctuation tendency, and the calculated fluctuation tendency can be displayed in a predetermined format.

  In the present embodiment, the intestinal state index value and the fluctuation tendency are displayed on the display unit 28 provided on the operation display panel 30. In other words, in the present embodiment, the display unit 28 functions as a display unit that displays a measurement result including the intestinal state index value and various precautions regarding the measurement. Further, the health condition measuring apparatus 1 includes display control means I in charge of display control for appropriately selecting the display content of the display unit 28.

  Therefore, the subject can easily visually recognize the variation tendency as well as the measured value and the intestinal state index value, and can know his / her health condition more accurately.

  By the way, as the intestinal state index value, for example, an index value called “intestinal age” using “age”, which is a concept frequently used in daily life, as a parameter can be used. In that case, the subject can intuitively know his / her intestinal state by recognizing how the intestinal state is compared to his / her actual age.

  In addition, the display control means I performs the measurement until the seating detection continuation time, which is the time during which the seating state detected by the seating detection unit 23 continues, after the subject sits on the toilet seat 13 reaches a predetermined first threshold value. As a precaution, a guide prohibiting toilet cleaning is displayed on the display unit 28. Further, as additional precautions, during this time, guidance for prohibiting the user from leaving the seated toilet 10 is also displayed on the display unit 28 at the same time.

  Here, the predetermined first threshold value is a standard time required until a normal concentration measurement value is obtained when a standard subject is a target and the measurement in the measurement is substantially completed. It can be applied as desired.

  Further, the display control means I displays the guidance prohibiting the toilet flushing described above on the display unit 28, and until the seating detection continuation time of the seating detection unit 23 reaches a predetermined first threshold value. It is also possible to prevent toilet cleaning from being performed by controlling the toilet cleaning operation in a controlled manner.

  As described above, according to the present embodiment, until the combined gas necessary for measurement is obtained in the effective seating detection continuation time, the disappearance of the combined gas from the bowl portion 12 due to toilet flushing or sitting away is caused by the action of the subject. Measurement failures can be prevented as much as possible.

  Here, a more specific configuration of the health condition measuring apparatus 1 will be described in detail. As shown in FIG. 1, the health condition measuring apparatus 1 opens a gas suction port 16 at the base in the bowl portion 12, and the odor treatment device through the gas suction port 16 through a duct 17 serving as a deodorizing exhaust passage. 18 communicates.

The odor processing device 18 is composed of a suction fan 19 and a deodorizing cartridge 20 on the lower side thereof, and is discharged from the body to the lower side of the odor processing device 18 when the subject defecates as shown in FIG. A gas sensor 21 is disposed as concentration measuring means A for measuring the concentration of a predetermined component (CO ₂ ) in the combined gas.

  The concentration measuring means A including the gas sensor 21 and the suction fan 19 are electrically connected to the control unit 22.

  The control unit 22 includes a microcomputer having an MPU, a ROM, a RAM, and the like and other necessary circuits. The ROM 22 functions as the health condition measuring device 1 and performs a processing method according to the concentration measurement time. A processing program for executing is stored. Further, this ROM serves as a storage unit 24 that functions as the above-described density measurement value storage means B, density measurement time storage means G, and time series data storage means J.

  And this control part 22 is the above-mentioned density | concentration measured value determination means C, intestinal state index value calculation means D, density | concentration measurement start detection means E, density | concentration measurement completion | finish detection means F, operation | movement information acquisition means H, and display control means Functioning as I.

  Incidentally, as described above, in the health condition measuring apparatus 1 according to the present embodiment, when the operation information acquisition unit H acquires predetermined operation information during measurement of a predetermined component concentration, or the concentration measurement end detection unit. As the concentration measurement value determination method performed by the concentration measurement value determination means C when F detects the measurement of the predetermined component concentration, the following three processes are performed according to the concentration measurement time.

  That is, when the concentration measurement time is less than a predetermined time, the concentration measurement value is discarded as no measurement result regardless of the concentration measurement value stored in the concentration measurement value storage means B, and no measurement result is obtained. When the concentration measurement time is equal to or longer than the predetermined time, the second peak of the concentration measurement value stored in the concentration measurement value storage means B as the measurement establishment is determined as the concentration measurement value. And a third process in which the maximum density measurement value stored in the density measurement value storage means B is used as the density measurement value when the density measurement time is equal to or longer than the predetermined time and there is no maximum peak value. It is.

In this embodiment, the concentration measurement time and the operation information are used as parameters for the concentration measurement value determination means C (control unit 22) to determine the concentration measurement value. That is,
First parameter: concentration measurement time when the concentration measurement end detection means F detects the end of measurement of the predetermined component concentration.
Second parameter: Presence / absence of predetermined operation information acquired by the operation information acquisition unit H during measurement of the predetermined component concentration of the predetermined component concentration.

  Hereinafter, among the operations in the health condition measuring apparatus 1 according to the present embodiment, a method for measuring the concentration of the predetermined component in the combined gas will be described in detail.

  FIG. 3 is an explanatory diagram showing a conceptual process flow of the predetermined component concentration measurement in the health condition measuring apparatus.

  As a trigger for starting measurement, measurement is started when either a measurement button provided on the operation unit 29 of the operation display panel 30 is operated or an action of the subject sitting on the toilet seat 13 is performed.

  Then, after the measurement is started, the measurement end button provided on the operation unit 29 is operated until the predetermined time Ta that is the first threshold value in the present invention elapses after the measurement starts, or the toilet seat 13 is operated. Judgment processing is performed as to whether or not an abnormal motion of the subject, such as leaving the seat, has been detected by the motion information acquisition means H (step S101). During the measurement, when the measurement is started, the concentration measurement values periodically output by the gas sensor 21 are sequentially stored in the concentration measurement value storage means B. The predetermined time Ta is preferably at least 20 seconds or longer.

  In the present embodiment, the operation of various devices such as toilet cleaning and local cleaning (including hot air drying) of the seated toilet 10 is prohibited on the display unit 28 of the operation display panel 30 with the start of measurement. The operation guidance display is performed. This operation guide display may be a guide for notifying that the toilet cleaning function and the local cleaning function are controlled to be invalidated inside the apparatus. Moreover, you may include both guidance.

  If either measurement end or abnormal operation is detected (step S101: Yes), it is determined that measurement is not established and an “error message” is displayed on the display unit 28 of the operation display panel 30 (step S101). S111), the process proceeds to the “discard measurement data” process, discards the acquired density measurement value data (step S112), and ends the measurement process.

  Thus, the above-described process flow of step S101 → step S111 → step S112 corresponds to the first process in the present invention.

  On the other hand, in step S101, if the measurement end operation or abnormal operation of the subject is not detected from the start of concentration measurement and a certain concentration measurement time (predetermined time Ta) has passed (step S101: No), “measurement end” in step S121. Proceed to the process. In this measurement end processing, measurement by the gas sensor 21 is stopped, and those for which the operation functions of various devices have been forcibly turned off (prohibited) are returned to the on state.

  Next, in step S122, it is determined based on the obtained measurement result whether or not the measurement performed so far is a normal measurement with which a correct measurement result is obtained. As the determination method, in the present embodiment, a method of determining by the maximum peak value, which is a well-known technique in measurement using a sensor, is used. That is, it is determined whether or not there is a maximum peak value in the concentration measurement value group that has been measured and stored in the storage unit 24 in time series.

  Here, the method will be described. The graph shown in FIG. 6 is an example showing changes in sensor measurement values during the measurement time, with the sensor output value output from the gas sensor 21 on the vertical axis and the measurement time on the horizontal axis. In the present embodiment, as shown in the figure, a value obtained by subtracting the minimum output value Vmin from the maximum peak value Vmax in the peak value group of the output of the gas sensor 21 is set as the maximum peak value Vp of the sensor output.

  If it has the maximum peak value, the process proceeds to the “predetermined component concentration calculation” process of step S123 in order to determine the normal measurement and calculate the concentration of the predetermined component. In the predetermined component concentration calculation processing, the maximum peak value Cp of the predetermined specific component concentration is calculated based on a conversion formula (calibration curve) Cp = f (Vp) between the maximum peak value Vp and the specific component concentration. That is, the concentration corresponding to the maximum peak value of the concentration measurement value is set as the predetermined component concentration in this measurement.

  In step S124, an “intestinal state index calculation” process is performed based on the predetermined component concentration value obtained in step S123.

  When the “intestinal state index calculation” process is completed and the intestinal state index value is obtained, this intestinal state index value is stored in the time series data storage means J together with the measurement time information as time series data for each subject. Save (step S125) and finish the measurement process.

  In this way, the process flow of the above-described step S101 → step S121 → step S122 → step S123 → step S124 → step S125 corresponds to the second process.

  In the process of step S125, the subject can select whether or not to store a specific intestinal state index value in the time-series data storage unit J by the time-series data selection unit M described later. Also good.

  At this time, when the set time Tb, which is the second threshold value of the predetermined time in the present invention, elapses, for example, when the trigger for starting the measurement is the seating detection of the subject on the toilet seat 13, the motion information by the motion information acquisition means H Regardless of the acquisition, the operation of various functions of the seated toilet 10, for example, the operation for demonstrating the cleaning function is made effective, and the operation guidance display of the display unit 28 is also turned off.

  This is because the measurement of the health condition measuring apparatus 1 involves an excretion action, so that the time when the subject has finished unpleasant excretion can be shortened by his / her own intention. Therefore, the time Tb is appropriately set to a time longer than the time necessary for the measurement (predetermined time Ta), for example, a time when the subject does not hinder measurement even if the subject performs toilet cleaning or local cleaning. do it.

  In step S122, when the concentration measurement value does not have the maximum peak value (step S122: No), it is determined that there is a possibility of measurement abnormality, and the processing of “specific result display with caution message” in step S131 is performed. Proceed to Here, the measurement abnormality means that a certain concentration measurement time Ta, which is a necessary condition for obtaining a correct measurement result, has passed and this condition has been satisfied and a concentration measurement value has been obtained, but is adopted as a concentration measurement value. Is a measurement state in which suspicion occurs. For example, there is a case where the defecation action generating the combined gas is not completed, an abnormal operation occurs by the subject, or there is no defecation itself.

  In step S131, since there is no maximum peak value, the maximum value of the concentration measurement values obtained so far is set as the concentration measurement value, and an intestinal state index value is calculated based on this concentration measurement value, and this is specified. It will be the intestinal state index value. In this case, since there is no maximum peak value, an intestinal state index value that may be abnormal is displayed. At the same time, the display control means I displays that fact together with a caution message on the display unit 28.

  That is, when the peak is not detected from the concentration measurement value stored in the concentration measurement value storage unit B, the intestinal state index value calculation unit D sets the specific intestinal state index value and the display control unit I When the intestinal state index value is displayed on the display unit 28, a predetermined message for calling attention to a specific intestinal state index value is added and displayed.

  In this way, the process flow of the above-described step S101 → step S121 → step S122 → step S131 corresponds to the third process.

  The subject can select “whether or not to save” for the intestinal state index value and the concentration measurement value. That is, in step S132, the subject can select whether or not to store a specific intestinal state index value in the time-series data storage means J.

  As a means for the subject to select “whether or not to save”, for example, a selection operation button or the like may be provided as a time-series data selection unit in the operation unit 29 of the operation display panel 30.

  In that case, the control unit 22 functions as the fluctuation tendency calculating means K, calculates the fluctuation tendency of the intestinal state based on the above-described time series data recorded in time series for each subject, and calculates the calculated fluctuation tendency. The data can be displayed on the display unit 28 in a predetermined format, for example, a line graph shown in time series.

  Thus, when the subject chooses not to save (step S132: No), the specific intestinal state index value that may be an abnormal measurement result proceeds to the measurement data discarding process of step S112, while being discarded. When the subject selects to save (step S132: Yes), the process proceeds to “measurement result storage” in step S125, and then the measurement process ends.

  As described above, in the first processing method, when the concentration measurement time is less than the predetermined time Ta, the measurement is not established regardless of the value of the concentration measurement value stored in the concentration measurement value storage unit B. The density measurement value stored in the density measurement value storage means B is discarded and no measurement result is obtained. In this processing method, the density measurement is not performed as a result, and it is determined that there is no density measurement value. Is made.

  In the second processing method, when the concentration measurement time is equal to or longer than the predetermined time Ta, the maximum peak value of the concentration measurement value stored in the concentration measurement value storage means B as the measurement establishment is determined as the concentration measurement value. is there.

  In the third processing method, when the concentration measurement time is equal to or longer than the predetermined time Ta and there is no maximum peak value, the maximum value of the concentration measurement values stored in the concentration measurement value storage means B is determined as the concentration measurement value. To do.

  By the way, in the outline explanation of the processing flow described above, as the processing method when the control unit 22 (motion information acquisition means H) acquires the motion information, only the case where the time is less than the predetermined time Ta has been described. In some cases, the operation information is acquired after elapses. That is, this is a case where the control unit 22 (motion information acquisition means H) acquires the motion information during the period from S101 to S121 in FIG. 3, and the description in that case will be the entire health condition measuring apparatus 1 described below. This will be done in the explanation of the operation.

  Next, a specific flow of concentration measurement processing including the above-described concentration measurement processing operation of the control unit 22 will be described in more detail with reference to FIGS. 4 and 5.

  FIG. 4 is a flowchart of various processes in the health condition measuring apparatus, and FIG. 5 is an explanatory diagram showing an example of display contents on an operation display panel provided in the health condition measuring apparatus. Here, for example, a human body detection means (not shown) such as an infrared sensor is provided in the seating toilet 10 or a toilet booth where the seating toilet 10 is installed. Detection signal is output to the control unit 22.

  When a person approaches the seated toilet 10 provided with the health condition measuring device 1, the human body detecting means detects it and outputs a detection signal to the control unit 22 as shown in FIG. 4 (step S1).

  When the detection signal is received, the gas sensor 21 is turned on to stand by (step S2).

  Next, it is determined whether or not the seating detection unit 23 constituting the motion information acquisition unit H has detected the subject's seating (step S3). And when it determines with not detecting seating (step S3: No), a process is moved to step S31.

  In the process of step S31, the process waits until a predetermined time (for example, 5 minutes) elapses. When it is determined that the predetermined time has elapsed (step S31: Yes), the process proceeds to the process of “gas sensor power off” in step S14. This concentration measurement process is terminated.

  Here, for example, the time of 5 minutes, which is the determination criterion in step S31, assumes a case where a person approaches the seated toilet 10 for toilet cleaning, for example. That is, the case of not sitting within 5 minutes after detecting a human body is considered to be a toilet cleaning or at least not intending to measure the concentration of a predetermined component in the combined gas using the seated toilet 10. Therefore, it is not preferable to keep the gas sensor 21 in an on state forever from the viewpoint of energy saving.

  On the other hand, if it determines with having detected seating in step S3 (step S3: Yes), while the control part 22 will start measurement by the gas sensor 21, the elapsed time from concentration measurement start time will be carried out by the concentration measurement time memory | storage means G. Is stored as the concentration measurement time (step S4).

  In the present embodiment, the power of the gas sensor 21 is turned on in conjunction with the human body detection, and then the measurement is started with the trigger that the seating detection unit 23 detects the seating of the subject. Measurement may be started by a predetermined switch operation. In that case, no human body detection means is required.

  On the other hand, if the control unit 22 functions as the display control means I and determines that seating has been detected in step S3 (step S3: Yes), as shown in FIG. Please perform the guidance display process (L1) that displays “Please turn off the toilet bowl cleaning function OFF” and forcibly disable the toilet flushing switch function inside the device. Turn off.

  When the measurement is started in step S4 and the concentration measurement time is counted by the concentration measurement time storage unit G, the control unit 22 is sequentially output from the gas sensor 21 to the storage unit 24 (concentration measurement value storage unit B). The measured concentration value data is stored (step S5).

  Then, it is determined whether the elapsed time from the concentration measurement start time stored in the concentration measurement time storage means G is equal to or longer than the predetermined time Ta (step S6). And when it determines with it not being more than predetermined time Ta, a process is moved to step S21.

  In step S6, when it is determined that the predetermined time Ta or longer (step S6: Yes), until the concentration measurement end detection means F detects the end of measurement (step S7: Yes), the subject's sitting is monitored. Wait (step S81: No). Here, “measurement end detection” by the concentration measurement end detection means F is the operation of the measurement end button by the subject in this embodiment, but for example, a personal recognition button assigned to the operation display panel 30 for each of the plurality of subjects. (See FIG. 2).

  Then, if separation is detected during this time (step S81: Yes), since the concentration measurement has already been substantially completed, as shown in FIG. While performing guidance display processing (L2) such as “operation guidance OFF”, operation functions such as toilet flushing and local washing are effectively restored, and the standby state is continued until 5 minutes have elapsed from the sitting state (step S82: NO).

  If it is determined in step S82 that 5 minutes have passed since the user has left the seat (step S82: Yes), all the measurement data stored in the process of step S5 is discarded (step S83), and the gas sensor is processed in the process of step S14. The power supply 21 is turned off and the concentration measurement process is terminated.

  In other words, the health condition measuring device 1 of the present embodiment corresponds to a setting that can be used by a general user who uses it as a normal toilet device. Because it can occur in common with all users including the subject, wait for the measurement end operation, and if the time for sitting away is 5 minutes or more, it is due to the use of a user other than the subject who does not intend to continue the measurement. The process is advanced as a thing.

  On the other hand, when it is detected in step S7 that the measurement end operation button has been operated and the control unit 22 (concentration measurement end detection means F) detects the end of measurement (step S7: Yes), the “toilet bowl washing operation” By performing guidance display processing (L2) such as “function ON” and “operation guidance OFF”, operation functions such as toilet flushing and local washing are effectively restored, and concentration measurement values are stored in the storage unit 24 (concentration measurement value storage means). B) (step S8), and the process proceeds to step S9.

  When the concentration measurement value is stored in the storage unit 24 (concentration measurement value storage unit B), in step S9, the control unit 22 functions as the concentration measurement value determination unit C and determines whether or not the concentration measurement value has a maximum peak value. to decide. If there is a maximum peak value, the process proceeds to step S10. If there is no maximum peak value, the process proceeds to step S71.

  In step S10, the control unit 22 (concentration measurement value determining means C) determines a concentration measurement value that is a concentration of a predetermined component in the combined gas by a fixed process, and further performs an intestinal state index calculation in step S11. .

  In step S11, the control unit 22 functions as the intestinal state index value calculating means D, calculates the intestinal state index value by a predetermined process based on the obtained concentration measurement value, and then displays the measurement result in step S12. I do.

  In step S12, the control unit 22 (display control means I) displays the intestinal state index value obtained from the measured concentration of the predetermined component in the combined gas and notifies the subject. In step S12, based on the current measurement result and the measurement data stored in the time series data storage means J in the previous measurement processing, the control unit 22 functions as the fluctuation tendency calculation means K, The fluctuation tendency is calculated and displayed on the display unit 28 by, for example, a line graph shown in time series.

  Thereafter, the measurement data is stored in the time series data storage means J (step S13). And the power supply of the gas sensor 21 is turned off (step S14), and this concentration measurement process is complete | finished.

  In step S14, the gas sensor 21 is automatically turned off when the measurement data storage process in step S13 is completed. For example, when the output of the detection signal by the human body detection unit is stopped, The power source of the gas sensor 21 may be turned off.

  The processing flow described above corresponds to the second processing flow in the present invention described above. Next, the processing after step S21 when the measurement duration time is shorter than the predetermined time Ta in step S6 described above, that is, the first processing in the present invention described above will be described.

  If it is determined in step S6 that the measurement duration is shorter than the predetermined time Ta, whether or not there is an abnormal operation, that is, whether or not predetermined abnormal operation information such as a separation operation or a toilet seat cleaning operation is acquired by the operation information acquisition unit H. Is determined (step S21). If it is determined that there is no abnormality, it is next determined in step S22 whether or not the end of measurement has been detected (step S22), and if it is determined in step S22 that the end of measurement has not been detected, processing is performed. Is returned to the processing of “measurement data storage” in step S5. In this case, the measurement end determination is made when it is detected that the measurement end button provided on the operation display panel 30 is operated.

  That is, until the predetermined time Ta has elapsed from the start of measurement, unless the abnormal operation detection or the measurement end operation is detected by the operation information acquisition unit H, the concentration measurement value data sequentially output from the gas sensor 21 is stored one by one. It is stored in (concentration measurement value storage means B).

  On the other hand, if it is determined in step S21 that there is an abnormal operation, or if it is determined in step S22 that the end of measurement is detected, the control unit 22 moves the process to step S23 and informs the display unit 28 that the measurement is stopped. Display an error message to inform.

  Further, since no measurement is performed at this time, there is no problem even if toilet cleaning or local cleaning is performed. Therefore, as shown in FIG. 5, the control unit 22 turns off the operation guide prohibiting the toilet cleaning operation and the like and cleans the toilet. A guidance display (L2) for enabling the operation function is displayed on the display unit 28.

  And the control part 22 complete | finishes the memory | storage process of the density | concentration measurement value data to the memory | storage part 24 (concentration measurement value memory | storage means B) so far (step S24). In step S25, all the measurement data stored in step S5 is discarded, and in step S14, the gas sensor 21 is turned off and the concentration measurement process ends.

  As described above, when an abnormal operation is detected or a measurement end operation is detected while the concentration measurement continuation time is less than the predetermined time Ta, the concentration measurement value stored in the concentration measurement value storage means B is regarded as measurement failure. Regardless of the case, the concentration measurement value is discarded, and as a result, the measurement result becomes “none” (first processing).

  Next, processing when it is determined in step S9 that there is no maximum peak value will be described. The process in this case is the third process in the present invention.

  If it is determined in step S9 that there is no maximum peak value, the maximum concentration measurement value stored in the storage unit 24 (concentration measurement value storage means B) is displayed on the display unit 28 as a measurement value. At that time, a warning message indicating that there is a possibility of abnormality in the measured value is attached and displayed (step S71).

  Next, in step S72, a display for urging the subject to operate the selection operation button as to whether or not to save the measurement result is performed. This selection operation button corresponds to a time-series data selection unit, and is provided on the operation unit 29 of the operation display panel 30, for example.

  Next, the operation result of the selection operation button of the subject in step S73 is determined. If it is determined that “save” is selected, the measurement data is stored in the time-series data storage unit J (step S13). Thereafter, the power source of the gas sensor 21 is turned off (step S14), and the concentration measurement process is terminated.

  On the other hand, if it is determined that “do not save” is selected, the process proceeds to step S25, where all the measurement data stored in the process in step S5 is discarded, and the gas sensor 21 is turned off in the process in step S14. The density measurement process ends.
