By the way, it is preferable to place a health condition measuring device for measuring excreted gas on a toilet, since it can be measured without resistance without extra effort for the user. In particular, when the intestinal state is measured by being attached to a toilet bowl with a deodorizing device, it is convenient to attach a gas sensor in the exhaust passage for the deodorizing fan as described in Patent Document 3. In addition, since a certain amount of wind flows through the deodorizing fan exhaust passage, it is convenient to quantitatively measure the gas components discharged together with the excrement. In this case, the excretion gas discharged into the space of the toilet bowl is collected by a deodorizing fan and transported to a gas sensor for measurement. However, the dilution rate and recovery rate of the excretion gas are affected by the shape and size of the toilet bowl. As a result, the present inventors have revealed that when the shape and type of the toilet bowl are different, there is a problem that the measurement results are different and the intestinal state cannot be measured accurately.

An object of the present invention is to provide a health condition measuring apparatus that can be used for different types of toilets.

In order to solve the above-described problems, a health condition measuring apparatus according to the present invention includes a gas sensor that is placed on a toilet and measures a gas concentration that accompanies during defecation, and a gas concentration that is calculated from data from an output value from the gas sensor.

According to the present invention, the data used in the first calculation unit that calculates the gas concentration from the output value of the gas sensor corresponds to the toilet bowl on which the intestinal state apparatus measuring device is placed. Since the concentration of excretion gas can be accurately measured even if the diffusion state of excretion gas varies depending on the shape and size, the intestinal state can be measured without being affected by the in-place toilet.
As a preferred embodiment of the health condition measuring apparatus according to the present invention, the data is one data selected from data corresponding to a plurality of types of toilets. In the present embodiment, data corresponding to a plurality of toilets is stored in the first arithmetic unit, and for example, a data selection unit that selects toilet-corresponding data from the stored data is provided. As a result, since one health condition measuring device corresponds to a plurality of toilets, for example, even if the placed toilet changes, it is possible to save the trouble of updating the data of the first calculation unit to data corresponding to a new toilet. It is possible and suitable.
As a preferred embodiment of the health condition measuring apparatus according to the present invention, the data is data obtained by correcting data in a standard toilet. In this embodiment, data corresponding to a predetermined standard toilet is stored in the first calculation unit, and when placing a toilet other than the standard toilet, the standard toilet corresponding data is corrected according to the placed toilet. Thus, the data can be used as data corresponding to the toilet bowl, which is preferable.
Moreover, as a preferred embodiment of the health condition measuring apparatus according to the present invention, the health condition measuring apparatus and the toilet are integrated. In this embodiment, the health condition measuring device and the toilet are integrated, and the data used for the first calculation unit of the health status measuring device at the manufacturing stage is already compatible with the in-place toilet, It is preferable to save the trouble of making the data of the first calculation unit correspond to the in-place toilet later.

Embodiments of the present invention will be specifically described below with reference to the accompanying drawings. First, a first embodiment will be described with reference to FIGS.

FIG. 1 is an external view (partial perspective view) showing an example of a Western-style toilet with a built-in human body cleaning device equipped with the health condition measuring device of the present invention.

The exhaust passage 4 for a deodorizing fan is installed using the space provided between the toilet seat 2 of the toilet bowl 1 and the top of the toilet bowl 3 periphery. A deodorizing fan 5 and a gas sensor 7 are attached in the exhaust passage 4 for the deodorizing fan.

In addition, the first calculation unit 8 and the second calculation unit 9 are integrated and incorporated in the rear part of the toilet seat 2, and a display unit that displays intestinal state index data that is a result calculated by the second calculation unit 9. 10 is incorporated in the operation panel 11 of the human body washing apparatus. Data exchange between the gas sensor 7 and the first calculation unit 8 is performed by connection, and data exchange between the second calculation unit 9 and the display unit 10 is performed by infrared rays.

FIG. 2 is a conceptual diagram showing a first embodiment of the health condition measuring apparatus of the present invention. A deodorizing fan 5, a deodorizing cartridge 6, and a gas sensor 7 are arranged in this order from the windward side in the exhaust passage 4 for the deodorizing fan.

When the first calculation unit 8 transmits a measurement start signal to the gas sensor 7 and the gas sensor starts to operate, an output signal corresponding to the gas concentration of the gas conveyed by the deodorizing fan is obtained. The sensor output signal obtained by the gas sensor 7 is sent to the first calculation unit 8 and stored in time series. Further, the operation of the gas sensor is ended by the measurement end signal of the first calculation unit 8, and the recording of the sensor output signal is ended. Subsequently, the first calculation unit 8 obtains the gas concentration from the sensor output signal stored in accordance with the method described later, and transmits the result to the second calculation unit 9, where the intestinal state index is estimated and obtained. The intestinal state index is displayed on the display unit 10.
Hereinafter, the first calculation unit 8 that calculates the gas concentration will be described in detail. The first calculation unit 8 is a gas sensor control unit that controls the operation of the gas sensor, a first storage unit that stores an output signal of the gas sensor, a gas sensor that processes the output signal of the gas sensor and calculates an output value of the gas sensor corresponding to the gas concentration An output signal processing unit, a gas concentration calculation unit that calculates a gas concentration from the gas sensor output value via data corresponding to the toilet, a second storage unit that stores data corresponding to the toilet, and a second storage unit It consists of toilet bowl data. Hereinafter, data corresponding to a toilet is abbreviated as toilet-related data.
The gas sensor output signal processing unit extracts the maximum signal and the minimum signal from the sensor output signals stored in the first storage unit from the start of measurement to the end of measurement, and uses the difference between the two as the output value of the gas sensor. calculate. Subsequently, the gas concentration calculation unit calculates the gas concentration from the gas sensor output value via data calculated from the gas sensor output value stored in the second storage unit to the gas concentration. Since the data memorize | stored in the 2nd memory | storage part respond | corresponds to a placement toilet, the density | concentration of excretion gas can be calculated correctly irrespective of a toilet bowl.
In this embodiment, the toilet correspondence data stored in the second storage unit of the health condition measuring apparatus first calculation unit is composed of a correspondence table between gas sensor output values and gas concentrations. This correspondence table is determined in advance so as to correspond to the toilet bowl on which the health condition measuring device is placed.
Here, the determination method will be described. First, the necessity of this correspondence table corresponding to a toilet is described. Exhaust gas for the deodorizing fan in a state where the excretion gas discharged into the space (toilet space) formed between the toilet bowl and the buttocks when the user is sitting on the toilet bowl is diluted with the air in the toilet bowl space Measurement is carried from the suction port of the passage 4 to the gas sensor 7 through the exhaust passage 4 for the deodorizing fan. The present inventors have discovered that the dilution of excretion gas in the toilet bowl space is affected by the shape and size (depth, lateral spread, etc.) of the toilet bowl, and the concentration (exactly) of the excretion gas from the output of the gas sensor. In order to calculate the amount of excretion per unit time, the concentration is used for convenience in the present invention), the excretion gas in the stool space is diluted, that is, the influence of the specification of the toilet in which the health condition measuring device is installed I found it necessary to do.
In this embodiment, the data used by the calculation unit is used as the toilet-compatible data as a method for considering the influence of the toilet specification. That is, the data used by the first calculation unit of the health condition measuring apparatus is determined in advance so as to correspond to the toilet to be placed and stored in the calculation unit. Hereinafter, a method for determining toilet-corresponding data of the first calculation unit in the present embodiment will be described.
FIG. 3 is a conceptual diagram showing a test apparatus for determining toilet correspondence data. A health condition measuring device is incorporated in the toilet. Two gas pipes connected to a gas container 20 containing a target gas (carbon dioxide gas in this embodiment) and a gas container 21 containing nitrogen gas for diluting the target gas are joined from the middle. Connected to the merging pipe 24. The outlet of the pipe 24 is fixed so as to come to a position close to the assumed anal position when a human excretes in the toilet bowl space. Moreover, in order to approach the conditions at the time of excretion, the upper opening of the toilet bowl space is covered with a lid 25 so that the front and the rear are partially opened. The distal end of the gas pipe 24 is introduced into the toilet bowl space through a hole provided in the lid 25. In order to adjust the gas concentration and the input amount, the mass flows 22 and 23 are connected to the pipe before joining.
As a procedure to be performed, first, the health condition measuring device is activated to be ready for measurement, and then a certain amount of carbon dioxide gas adjusted to a constant concentration by mass flow 22 and 23 (300 mL in this embodiment) is given for a certain time (this implementation). In the example, it is introduced into the toilet bowl space over 2 seconds (the gas thus introduced is referred to as model gas). The obtained sensor output signal is taken out from the health condition measuring device. Correlation data between the sensor output and the gas concentration is acquired by changing the concentration of the model gas. Next, a correlation between the sensor output and the gas concentration is obtained from the correlation data, and a correspondence table for calculating the gas concentration from the output of the gas sensor is determined based on the correlation. The correspondence table thus determined is written and stored in the first calculation unit as data used by the first calculation unit of the health condition measuring apparatus.
Since the obtained gas concentration calculation data of the first calculation unit includes all influences such as the size of the toilet bowl to be placed and the shape of the toilet bowl, the data is data for the toilet bowl.
In this embodiment, the toilet-corresponding data is acquired by an experiment. However, a method of acquiring toilet-compatibility data by parameterizing the toilet information and evaluating its influence by a mathematical simulation method is also conceivable.

Next, a second embodiment of the health condition measuring apparatus of the present invention will be described. The apparatus configuration of the present embodiment is the same as that of the first embodiment shown in FIG. 2, but the configuration of the toilet corresponding data stored in the first calculation unit 8 and the second storage unit is different. That is, the toilet corresponding data of the present embodiment is composed of standard toilet corresponding data and a correction coefficient corresponding to a placed toilet (hereinafter abbreviated as a placed toilet corresponding correction coefficient). Since the standard toilet bowl correspondence data is the same as that in the first embodiment, the in-place toilet bowl correspondence correction coefficient will be described here.

FIG. 11 is a diagram for conceptually explaining the relationship between the gas sensor output and the gas concentration of the health condition measuring apparatus according to the present embodiment. The output of the gas sensor is processed so as to have a linear relationship with the gas concentration. When placed in a standard toilet, a correlation curve with a slope of αS is shown. On the other hand, when placed on toilet A, a correlation curve with an inclination of αA is shown. The correction coefficient when placed in toilet A is the ratio of both (αS / αA).
The following methods can be used to obtain toilet bowl correspondence data in this embodiment. First, a certain toilet is selected as a standard toilet, and the health condition measuring device of the present invention is placed on the selected toilet, and standard toilet compatible operation data is acquired according to the method described in the description of the first embodiment. It memorize | stores in a 1st calculating part. Next, the health condition measuring device of the present invention is placed on the target toilet, and the model gas is measured in the same manner. The output corresponding to the model gas obtained (VMA in FIG. 11) and the output corresponding to the model gas of the same concentration in the standard toilet (VMS in FIG. 11) are compared, and the correction coefficient corresponding to the toilet to be placed ( = VMS / VMA = αS / αA). The obtained correction coefficient is memorize | stored in the 2nd memory | storage part of a 1st calculating part with the said standard toilet bowl corresponding data.

The calculated correction coefficient can be stored in advance in the first calculation unit before being installed in the toilet as in the first embodiment, but in this embodiment, a correction coefficient input unit is provided in the health condition measuring apparatus. Thus, it is possible to input a correction coefficient corresponding to the toilet bowl at the installation site. FIG. 4 illustrates an operation flow for determining the first calculation unit by inputting the correction coefficient. That is, as an initial operation after the power is turned on, a correction coefficient corresponding to the placed toilet is input from the correction coefficient input unit, and the toilet corresponding data of the first calculation unit is determined.
The correction coefficient can also be determined by measuring the model gas at the installation site. This is particularly convenient when the health condition measuring apparatus of the present invention is mounted on a toilet that is not assumed in advance.

In the calculation from the gas sensor output to the gas concentration in the first calculation unit 8 of the present embodiment, first, the gas sensor output signal processing unit calculates the gas sensor output value by the same method as in the first embodiment. Subsequently, the gas concentration calculation unit corrects the gas sensor output value calculated via the correction coefficient for in-flight toilet stored in the second storage unit, and the correction value of the gas sensor output (correction value of the gas sensor output = gas sensor output) Value × correction coefficient). Next, the gas concentration is calculated from the correction value of the gas sensor output via the standard toilet corresponding data.
In the present embodiment, since the correction coefficient corresponds to the toilet bowl, the concentration of excretion gas can be calculated accurately regardless of the toilet bowl. In addition, since the correction coefficient can be obtained from the measurement of one model gas, it is possible to obtain the toilet correspondence data efficiently, which is preferable.
Subsequently, a third embodiment of the health condition measuring apparatus of the present invention will be described. The apparatus configuration of this embodiment is the same as that of the first embodiment shown in FIG. 2 except that the first calculation unit 8 includes data and selection units corresponding to a plurality of types of toilets.
FIG. 5 is a conceptual diagram showing the configuration of the first calculation unit of this embodiment. The first arithmetic unit 8 has toilet A, toilet B. . . A toilet bowl X and a plurality of toilet bowl correspondence data are stored, and each is connected to the selection unit 12. The health condition measuring apparatus according to the present embodiment includes a toilet information input unit, and the selection unit 12 includes a toilet information receiving unit. The selection unit 12 selects data corresponding to a predetermined toilet from a plurality of toilet correspondence data stored based on the toilet information input by the toilet information input unit, and is a concentration calculation data of the first calculation unit 8 Determine the corresponding data.
FIG. 6 is a flowchart illustrating an initial operation for determining data of the first arithmetic unit in the present embodiment. After placing the health condition measuring device on the toilet and turning on the power, the toilet information is input from the toilet information input unit by the panel operation. The input toilet information is transmitted to the selection unit of the first calculation unit, the data corresponding to the toilet of the information input by the selection unit is selected, the toilet correspondence data of the first calculation unit is determined, and the initial operation is completed To do.
In this embodiment, toilet information is input by operation, but if the health condition measuring device is provided with an automatic recognition function that automatically recognizes a toilet, and installed in the toilet, the process from toilet recognition to selection of toilet-compatible data is performed. A series of operations may be automatically performed.
In addition, as a common embodiment corresponding to Example 1 to Example 3, an example in which the intestinal state apparatus is placed on the toilet bowl from the manufacturing stage is used as the toilet-integrated health condition measuring apparatus. In this case, since the data used for the gas concentration calculation of the first calculation unit of the health condition measuring apparatus is designed from the beginning to correspond to the toilet bowl, the initial operation for determining the first calculation unit is omitted. In addition, it is convenient because the labor for measuring the health condition and handling the toilet in the distribution stage is reduced.
The health condition measuring apparatus of the present invention has been described based on the in-urinal correspondence data, which is the gas concentration calculation data of the first arithmetic unit, and the initial operation after placing the toilet, based on the drawings of the embodiments.
Subsequently, a method of estimating the gas concentration from the gas sensor output and the intestinal state index from the gas concentration of the health condition measuring apparatus of the present invention will be described. In this example, carbon dioxide was used as the gas, and fecal pH was used as an example of the intestinal index. First, a procedure for calculating the gas concentration from the output of the gas sensor by the first calculation unit will be described.
FIG. 7 is a graph showing an output example when the gas sensor 7 measures the carbon dioxide gas concentration in the gas generated during defecation. The time (seconds) on the horizontal axis represents the time required for defecation, t1 is the start of defecation, and t2 is the end of defecation. Since the maximum output corresponds to the timing when the amount of defecation is the largest, the more accurate pH value can be estimated by using the output value (maximum peak value Vp) at this time.
Using the Vp value as the output of the gas sensor 7, the first calculation unit calculates the carbon dioxide gas concentration Cp corresponding to the maximum peak value Vp by using the toilet correspondence data.
Next, a procedure for calculating the fecal pH of the intestinal state index from the calculated carbon dioxide gas concentration Cp will be described.

FIG. 8 is actual measurement data showing the correlation between the maximum value of carbon dioxide gas concentration (expressed in volume%) in the gas generated during defecation and the acetic acid concentration (μmol / g) in the stool collected at that time. The reason why there is a correlation between the carbon dioxide gas concentration and the acetic acid concentration is not clear, but the pH value of feces depends on the concentration of the carboxylic acid contained, and a certain percentage of this carboxylic acid is in the body. It is presumed that it is decomposed into water and carbon dioxide.

Therefore, the concentration of acetic acid occupying most of the carboxylic acid is also correlated with the carbon dioxide gas concentration. FIG. 9 shows measured data indicating the correlation between the acetic acid concentration in the stool and the pH value in the stool. Although the data is somewhat disturbed by the influence of other acids and bases contained therein, the data is almost linear. Is shown.
When the calculation from the output of the carbon dioxide gas sensor to the gas concentration is completed in the first calculation unit, the obtained carbon dioxide gas concentration value is transmitted to the second calculation unit. The second computing unit 9 stores a correspondence table between the carbon dioxide gas concentration and the acetic acid concentration based on the correlation data shown in FIG. 8, and a correspondence table between the acetic acid concentration and the fecal pH based on the correlation data shown in FIG. The acetic acid concentration is estimated from the carbon dioxide gas concentration and the fecal pH is estimated from the acetic acid concentration according to the stored correspondence table.
Finally, the procedure of the intestinal state measuring method using the health state measuring apparatus of the present invention will be exemplified and described.
FIG. 10 is an example showing a procedure of a health condition measuring method using a health condition measuring apparatus of the present invention (built in a sanitary washing toilet seat apparatus attached to a western toilet). The operation of the user (hereinafter referred to as “user”) is displayed on the left side, and the process performed by the toilet seat device (including the process of the health condition measuring apparatus) is displayed separately on the right side.

As shown in the flow of this figure, the user enters the toilet, defecates, and then exits, but since the health condition measuring device of the present invention is attached to this toilet, By displaying the estimated pH value on the display unit 10, it is possible to know the physical condition of the day, or to know the change in physical condition over time when continuously measured.

First, when the user enters the room, the human body detection sensor detects the room entry, and the gas sensor control unit of the first calculation unit 8 activates the carbon dioxide gas sensor 7. When the human body detection sensor is not used, the user may manually turn on the health condition measuring device.

When the user is seated, the seating sensor detects the seating, and the deodorizing fan 5 and the carbon dioxide gas sensor 7 are activated by the gas sensor control unit of the first calculation unit 8. Here, the time of the sensor at the start of operation is defined as t1, and the output signal value of the carbon dioxide gas sensor 7 corresponding to the time is referred to as V1. Note that the gas sensor may be started without the use of a seating sensor by the user pressing the sensor start switch.

Until the user starts and finishes defecation, the carbon dioxide gas sensor 7 detects the data Vx every predetermined time tx, for example, every second, and writes them in the first storage unit of the first calculation unit 8.

After defecation ends, the user starts washing the human body. At this time, the recording of the carbon dioxide gas sensor 7 is terminated in conjunction with the cleaning button. The time t2 at the end of the defecation and the detection data V2 at that time of the carbon dioxide gas sensor 7 are stored. When considering that the washing button may be used before or during defecation, the user may manually terminate the storage without interlocking with the washing button.

Next, the first calculation unit 8 searches for the maximum value Vmax of the carbon dioxide gas output signal value in the range of t1 to t2. A value obtained by subtracting the minimum value of the carbon dioxide gas output signal value from Vmax is recorded as the output value (maximum value Vp) of the carbon dioxide gas sensor corresponding to excretion gas. Then, the carbon dioxide gas maximum concentration Cp is calculated from the Vp value.

Subsequently, the second calculation unit 9 estimates the acetic acid concentration, and further estimates the pH value from the acetic acid concentration. The calculated pH value is written in the second calculation unit 9, and the result is simultaneously notified to the user by the display unit 10 or the like.

When the user leaves the seat, the seating sensor senses it and the deodorizing fan 5 stops. When the user leaves the room, the human body detection sensor detects that the room has been left, and the signal is sent to the gas sensor control unit of the first calculation unit 8 to turn off the carbon dioxide gas sensor 7.

In addition, although the carbon dioxide gas sensor was used in the present Example, even if it uses a hydrogen gas sensor, a hydrogen sulfide sensor, etc., it can measure an intestinal state index similarly by using the conversion method corresponding to it. it can.
