Description

  The present invention relates to an excrement amount measuring apparatus, and more particularly to an excrement amount measuring apparatus that individually measures stool volume and stool volume.

In chemotherapy after transplantation of organs including bone marrow, for example, as shown in the guidelines for hematopoietic cell transplantation, the progress of rejection especially after transplantation can be observed by managing stool such as measurement of stool volume and observation of stool status. Therefore, it is necessary to measure the volume of stool and urine respectively.
Therefore, conventionally, as described in Patent Document 1, for example, a biological information measurement device that estimates the amount of defecation by measuring the concentration of carbon dioxide in the defecation gas discharged during defecation is known. In addition, as described in Patent Document 2, urination information measurement is performed in which two measurement pipes are provided and the urine volume and urine flow rate are measured in consideration of the specific gravity of urine by measuring the water level change in the bowl portion. The device is known.
However, in the biological information measuring device described in Patent Document 1, the concentration of carbon dioxide in the defecation gas discharged during defecation is measured, and the amount of defecation (stool amount) from the correlation between the carbon dioxide gas concentration and the amount of defecation. Therefore, there is a problem that the amount of urine cannot be measured.
Further, in the urination information measuring device described in Patent Document 2, it is possible to measure the urine volume in consideration of the specific gravity of urine by providing two measurement pipes and measuring the water level change in the bowl portion. However, there was a problem that stool volume could not be measured.
That is, the methods described in Patent Document 1 and Patent Document 2 described above have a problem that individual measurement cannot be realized in a state where urine and stool are mixed.
Therefore, as a method of measuring the urine volume and the stool volume, the user discharges the filth into the portable toilet, and then the medical worker collects the filth and performs individual measurements.

In this embodiment, the specific gravity of the urine is registered in advance as specific gravity 1.0 in the specific gravity registration means. Note that the specific gravity of urine registered in advance in the specific gravity registration means is not limited to 1.0.

  The specific gravity of stool is determined by the user himself / herself judging the state of stool according to the commonly known Bristol scale (the stool hardness is divided into 7 levels) and inputting that state as stool state information. The specific gravity of the stool is registered in the specific gravity registration means 91. For example, the specific gravity is 1.1 for the dropping shape (types 1 and 2), the specific gravity is 1.05 for the banana shape (types 3 and 4), and the specific gravity is 1.5 for the water-soluble or floating shape (types 5 and 6). 0 is registered.

The stored water amount calculating means 92 obtains the amount of change in the stored water level from the amount of change in the stored water pressure measured by the measuring unit 8. And the change of the stored water level obtained by applying the obtained amount of change of the stored water level to the calibration curve stored in advance in the calibration curve storage unit 93 and allowing only the first measurement pipe 81 to communicate therewith. A change amount (first change amount) of the amount of stored water corresponding to the amount is calculated. Similarly, a change amount (second change amount) of the accumulated water amount corresponding to the change amount of the accumulated water level obtained when only the second measurement pipe line 82 is communicated is calculated. The amount of change in the accumulated water level indicates the difference between the accumulated water level before the user excretes and the accumulated water level after the user excretes.

  The individual excrement amount calculation means 94 calculates the excretion amount of excrement into stool amount and urine amount based on the value registered in the specific gravity registration means 91 and the value calculated by the stored water amount calculation means 92. Is. The individual excretion amount calculating means 94 can also calculate the amount of urine and the specific gravity of the urine when the user designates that the user has excreted only the urine. Therefore, in this embodiment, a specific gravity value of 1.0 is used as the specific gravity of urine. However, when the specific gravity user excretes only urine, the specific gravity of urine calculated by the individual excrement amount calculating means 94 is used. May be registered in the specific gravity registration means 91, and the specific gravity of the urine may be used after the next measurement. Note that the specific gravity of urine registered in the specific gravity registering unit 91 in advance is used until the specific gravity of urine is calculated by the individual excretion amount calculating unit 94 and the value is registered in the specific gravity registering unit.

  In FIG. 3, the measurement start water level forming unit 10 includes a water replenishment tank 103, a water supply pump 104, an on-off valve 106, and a pipe line 105 provided with the water supply pump 104 and the on-off valve 106. .

The supplementary water tank 103 is in communication with the accumulated water forming water supply pipe 217. The on-off valve 101 provided in the accumulated water forming water supply pipe line 217 opens and closes the supply of water to the supplementary water tank. The water supply to the replenishing tank 103 is stopped when a predetermined amount is detected by the float switch 102. However, when a malfunction occurs, the supplied water is discharged from the overflow pipe 107 through the trap tank 87 through the drain pipe connection pipe 863 and discharged toward the drain pipe 26. In this way, even if a malfunction occurs in the apparatus, consideration is given so that water leakage to the outside of the apparatus does not occur. The trap tank 87 is a drain tank that performs a trap function for the drain pipe 26 in order to discharge surplus water such as overflow water generated by the operation of each part to the drain pipe 26.
The pipe line 105 communicates with the second measurement pipe line 823 via a branch fitting 824 provided in the middle of the second measurement pipe line 823 and also communicates with the water replenishment tank 103. The pipe line 105 is opened and closed by an on-off valve 106.

  The procedure for forming the measurement start water level (Y) is as follows. First, the water supplied to the replenishment tank 103 is supplied to the pipe line 105 by the water supply pump 104. Thereafter, the liquid passes through the second measurement pipe 823 and is supplied to the bowl 22 through the second opening 821. In this way, the measurement start water level (Y) is formed.

  In the present embodiment, the measurement start water level (Y) formed by the measurement start water level forming unit 10 is a lower water level than the overflow water level (H), and the overflow water level (H) due to the excretion of the user. The position is set so as not to exceed. According to the applicant's knowledge, the maximum total amount of human excreta is 1400 mL. Therefore, the position obtained by subtracting 1400 mL from the overflow water level (H) may be set as the measurement start water level (Y). In addition, since the total excretion amount does not frequently exceed 800 mL, the measurement start water level (Y) may be set from the substantial total excrement amount measurement range. The position of the measurement start water level (Y) can be changed depending on how the measurement range specification of the apparatus is set.

  Further, in FIG. 2, the calibration curve creation unit 11 is provided to obtain and store in advance a calibration curve indicating the relationship between the stored water level and the stored water amount in the bowl 22 of the toilet 2 to be used. In particular, when the bowl 22 is a pottery, there is a large variation in the shape and size of each toilet bowl. When the excrement amount measuring apparatus 1 is installed by the calibration curve creating unit 11, a calibration curve indicating the relationship between the stored water level and the stored water amount is obtained and stored in the calibration curve storage unit 93. This calibration curve is rewritten during regular verification. The level of the stored water 23 formed in the bowl 22 of the toilet bowl 2 is also affected by the floor inclination at the installation site, the internal pressure of the drainage pipe 26, etc. Therefore, it is preferable to create a calibration curve at the time of installation.

In FIG. 3, the calibration curve creation unit 11 includes an on-off valve 111, a calibration pump 112, and a pipeline 113 provided with the on-off valve 111 and the calibration pump 112.
The on-off valve 111 is an on-off valve for opening and closing the pipe line 113. The calibration pump 112 is a pump for sucking the stored water 23 and can suck an arbitrary amount. The pipe 113 has an open end 113 a, communicates with the second measurement pipe 823 via a branch fitting 825 provided in the middle of the second measurement pipe 823, and communicates with the trap tank 87. ing.

  In the present embodiment, the procedure for obtaining a calibration curve indicating the relationship between the stored water level and the stored water amount is to first set the water level of the stored water 23 to the overflow water level (H) after the excrement amount measuring apparatus 1 is installed. Thereafter, using only the first measurement pipe 812, water is sucked from the stored water 23 by a predetermined amount by the calibration pump 112 from a state where the stored water level is the overflow water level (H). The sucked water is discharged to the drain pipe 26 through the trap tank 87 and the drain pipe connecting pipe line 863. Each time suction is performed by the calibration pump 112, the accumulated water pressure is measured by the pressure sensor 842. The stored water pressure measured by the pressure sensor 842 is converted into a stored water level, and the stored water level and the stored water amount are stored in a calibration curve storage unit 93 (not shown). In this way, the calibration curve creation unit 11 obtains the relationship between the stored water level and the stored water amount as a calibration curve and stores it in the calibration curve storage unit 93.

  In addition, you may obtain | require the calibration curve which shows the relationship between a stored water level and the amount of stored water using the 2nd measurement line 823 instead of the 1st measurement line 812. FIG. This is because, in the case of a liquid having a uniform specific gravity, such as when the stored water 23 is only water, the stored water level and the amount of stored water can be determined by using either the first measurement pipe 812 or the second measurement pipe 823. This is because the relationship does not change.

  Moreover, when the individual difference of the shape in the bowl 22 of the toilet bowl 2 to be used is small and the relationship between the accumulated water level and the accumulated water amount is constant, the relationship between the accumulated water level and the accumulated water amount in the calibration curve creation unit 11 or the like is shown. A configuration relating to obtaining a calibration curve may be omitted, and a calibration curve created in advance may be stored in the calibration curve storage unit 93 as an individual calibration curve. For example, this configuration can be applied to a toilet bowl in which at least the bowl 22 is made of resin.

  The measurement pipe line 843 has an atmosphere open end 843a that extends into the trap tank 87 and is opened to the atmosphere. Since the measurement pipe line 843 in the present embodiment is formed by a narrow pipe having a predetermined inner diameter, the vibration component transmitted through the measurement pipe line due to the ripple of the water surface of the accumulated water 23 due to urination can be fluidically attenuated. The pressure sensor 842 can measure the water pressure of the stored water 23 with higher accuracy.

  In addition, since the output of the pressure sensor 842 changes depending on the temperature change of the installed environment and the change of the sensor itself over time, the measurement conduit 843 also has a function of a calibration tube for calibrating the output of the pressure sensor 842. ing. That is, with the on-off valves 111, 832, 834 closed and the on-off valves 106, 835, 841 opened, the water supply pump 104 is operated to guide the water stored in the supplementary water tank 103 to the measurement line 843, and By overflowing into the trap tank 87 from the open end 843a to fill the measuring pipe 843 with water, a water column having a height equal to the length of the measuring pipe 843 having a fixed length is created. ing. Then, by measuring the water head pressure of the water column of a certain height with the pressure sensor 842, output calibration is performed to associate the relationship between the output value of the pressure sensor 842 and the water level with the water level value based on the atmospheric pressure at the time of calibration. .

In FIG. 2, the operation unit 5 includes the toilet remote controller 51 and the excrement amount measuring apparatus remote controller 52 as described above.
Although not shown, the remote controller 51 and the remote controller 52 are provided with switches for performing various operations. When the switches provided on the remote controllers 51 and 52 are operated, each operation corresponding to the switch is transmitted as an operation signal to the control unit 9 operating by the microcomputer by wireless communication means such as infrared communication. As described above, the excrement amount calculation unit 7 and the toilet function unit 3 of the excrement amount measurement device 1 are controlled by the control unit 9.

  Operation | movement of the excrement amount measuring apparatus in a present Example is demonstrated using FIG. 2 and FIG.

  In the present embodiment, the water level of the stored water 23 is held at the measurement start water level (Y) that is equal to or lower than the overflow water level (H). Therefore, preparation time for changing the water level is not required for excretion amount measurement, and the user can excrete without waiting time for preparation. Moreover, since preparation time is unnecessary, it is convenient for the user.

After the measurement start water level (Y) is formed and before the user excretes, the pressure sensor 842 measures the accumulated water pressure.
First, a pressure sensor 842 measures the accumulated water pressure when only the first measurement pipe line 812 communicates with the accumulated water 23. That is, among the three on-off valves that are the measurement line switching means 83, the on-off valve 832 is opened, and the on-off valve 834 and the on-off valve 835 are closed. Next, the stored water pressure when only the second measurement pipe line 823 is communicated with the stored water 23 is measured by the pressure sensor 842. That is, among the three on-off valves that are the measurement line switching means 83, the on-off valve 832 is closed, and the on-off valve 834 and the on-off valve 835 are opened.
In this way, when only the first measurement line 812 is communicated with the accumulated water 23, the accumulated water pressure before the user excretes, and only the second measurement line 823 is communicated with the accumulated water 23. In this case, the accumulated water pressure before the user excretes is stored in a memory (not shown).
In addition, in order to make a user's waiting time unnecessary, it is preferable to perform the measurement of the accumulated water pressure immediately after the formation of the measurement start water level (Y). However, since the pressure sensor 842 measures a minute pressure change, when using a semiconductor pressure sensor that is assumed as a specific implementation method, it is assumed that the sensor is subject to drifts such as fluctuations in the ambient environment temperature. The When priority is given to measurement accuracy, it should be performed immediately before the user's excretion, and the sequence should be selected with the expected accuracy.

  After the user excretes stool and urine, the specific gravity registration switch of the remote control 52 for the excrement amount measuring device is operated. As described above, the specific gravity of the stool is registered by the user determining the stool state based on the Bristol scale and inputting the state as the stool state information. That is, if the stool is in a banana state, the specific gravity registration switch 91 is operated to select “banana shape” from the stool state, so that the specific gravity registration means 91 has a specific gravity corresponding to “banana shape”. 1.05 is registered. Therefore, it is not necessary to separately provide a device for calculating the specific gravity of stool. Therefore, the excrement amount measuring apparatus 1 can be made compact.

  After registering the specific gravity of stool and urine, when the measurement start switch of the remote control 52 for the excrement amount measuring device is operated, the “measurable” displayed on the display unit (not shown) provided on the remote control 52 for the excrement amount measuring device "" Changes to "Measuring".

First, the piping is communicated so that the accumulated water pressure is measured when only the first measurement pipe line 812 is communicated with the accumulated water 23. That is, among the three on-off valves that are the measurement line switching means 83, the on-off valve 832 is opened, and the on-off valve 834 and the on-off valve 835 are closed. At this time, the accumulated water pressure measured by the pressure sensor 842 is the accumulated water pressure after the user excretes. Furthermore, the difference between the measured accumulated water pressure and the previously measured accumulated water pressure (the accumulated water pressure before the user excretes when only the first measurement line 812 is communicated with the accumulated water 23) by the pressure sensor. From this, the amount of change in the accumulated water pressure is measured.
Thereafter, the stored water amount calculation means 92 obtains the amount of change in the water level of the stored water from the amount of change in the stored water pressure measured by the pressure sensor 842. Then, the calculated amount of change in the stored water level is applied to the calibration curve stored in advance in the calibration curve storage unit 93 to calculate the first variation when only the first measurement pipeline 812 is communicated. . The calculated first change amount value is stored in a memory (not shown).

Next, the piping is communicated so that the accumulated water pressure is measured when only the second measurement pipe line 823 is communicated with the accumulated water 23. That is, the on-off valve 834 and the on-off valve 835 are opened, and the on-off valve 832 is closed. At this time, the accumulated water pressure measured by the pressure sensor 842 is the accumulated water pressure after the user excretes. Furthermore, the difference between the measured accumulated water pressure and the previously measured accumulated water pressure (the accumulated water pressure before the user excretes when only the first measurement line 812 is communicated with the accumulated water 23) by the pressure sensor. From this, the amount of change in the accumulated water pressure is measured.
Thereafter, the stored water amount calculation means 92 obtains the amount of change in the water level of the stored water pressure from the measured amount of change in the stored water pressure. Then, the calculated amount of change in the stored water level is applied to the calibration curve stored in advance in the calibration curve storage unit 93 to calculate the second variation when only the second measurement pipe line 823 is communicated. . The calculated second change value is stored in a memory (not shown).

  Next, the stool volume and the urine volume are respectively calculated by the individual excrement volume calculation means 94. In the individual excrement amount calculation means 94, the values obtained so far (specific gravity of stool, specific gravity of urine, first change amount, second change amount) are applied to a formula obtained based on the measurement principle described later. Then, the stool volume and the urine volume are calculated.

  The measurement results (calculated stool volume and urine volume) are displayed on the display unit 521 provided on the remote control 52 for the excrement amount measuring apparatus so as to be confirmed by the user, or printed on a printer provided in the toilet. Or sent to a personal computer used by medical personnel along with personal information and measurement time.

  When the user operates the toilet remote control 51 and starts the toilet cleaning operation, “Preparation” is displayed on the display unit 521 of the remote control 52 for the excrement amount measuring apparatus and the toilet cleaning is started. In toilet bowl cleaning, rim cleaning is performed to wash the bowl 22 with water discharged from the rim water spouting port 215, siphon phenomenon is generated by water discharged from the jet water discharging port 821, and the accumulated water 23 and excrement are discharged to the drain pipe 26. .

Thereafter, in order to form the measurement start water level (Y), first, the on-off valve 835 and the on-off valve 111 are closed, and the on-off valve 834 and the on-off valve 106 are opened, and the pipe line 105 and the second measurement pipe line are opened. The water supply pump 104 is operated at a predetermined water supply rate for a predetermined time in a state where the water replenishment tank 103 and the stored water 23 are communicated with each other by the air flow 823, and water stored in the water replenishment tank 103 is discharged from the jet outlet 821. . As a result, the water level of the stored water 23 becomes the measurement start water level (Y), which is a predetermined level higher than the water level (X) of the trap 24.
After the measurement start water level (Y) is formed in this way, when the accumulated water pressure before the user excretes is measured by the pressure sensor 842, the display unit 521 provided in the remote control 52 for the excrement amount measuring device. The text “Preparing” displayed on the screen changes to “Measurable” and the measurement of the amount of excreta is completed.

  Next, the operation when the specific gravity of the urine calculated by the individual excretion amount calculating unit 94 is registered in the specific gravity registration unit 91 as the specific gravity of the urine will be described.

  In the operation when the user designates that only the urine is excreted, the water level of the stored water 23 is held at the measurement start water level (Y) below the overflow water level (H) as in the above-described operation. . In addition, when only the first measurement line 812 communicates with the accumulated water 23, the accumulated water pressure before the user excretes, and when only the second measurement line 823 communicates with the accumulated water 23, the user The stored water pressure before excretion is also stored in a memory (not shown).

After the user excretes only the urine, the specific gravity registration switch of the remote controller 52 for the excrement amount measuring device is operated. At this time, when only the urine is excreted, since there is no stool, the user inputs that there is no stool state information. With this input, the specific gravity 0 is registered in the specific gravity registration means 91 as the specific gravity of the stool. That is, the case where the specific gravity of the stool is registered as 0 in the specific gravity registration means 91 is a case where the user designates that only the urine is excreted.
After the specific gravity of the stool is registered, when the user operates the measurement start switch of the remote control 52 for the excrement amount measuring device, “measurable” displayed on the display unit 521 provided on the remote control 52 for the excretion amount measuring device. The text changes to the text “Measuring”.

First, the piping is communicated so that the accumulated water pressure is measured when only the first measurement pipe line 812 is communicated with the accumulated water 23. That is, among the three on-off valves that are the measurement line switching means 83, the on-off valve 832 is opened, and the on-off valve 834 and the on-off valve 835 are closed. At this time, the accumulated water pressure measured by the pressure sensor 842 is the accumulated water pressure after the user excretes. Furthermore, the difference between the measured accumulated water pressure and the previously measured accumulated water pressure (the accumulated water pressure before the user excretes when only the first measurement line 812 is communicated with the accumulated water 23) by the pressure sensor. From this, the amount of change in the accumulated water pressure is measured.
Thereafter, the stored water amount calculation means 92 obtains the amount of change in the water level of the stored water pressure from the measured amount of change in the stored water pressure. Then, the calculated amount of change in the stored water level is applied to the calibration curve stored in advance in the calibration curve storage unit 93 to calculate the first variation when only the first measurement pipeline 812 is communicated. . The calculated first change amount value is stored in a memory (not shown).

Next, the piping is communicated so that the accumulated water pressure is measured when only the second measurement pipe line 823 is communicated with the accumulated water 23. That is, the on-off valve 834 and the on-off valve 835 are opened, and the on-off valve 832 is closed. At this time, the accumulated water pressure measured by the pressure sensor 842 is the accumulated water pressure after the user excretes. Furthermore, the difference between the measured accumulated water pressure and the previously measured accumulated water pressure (the accumulated water pressure before the user excretes when only the first measurement line 812 is communicated with the accumulated water 23) by the pressure sensor. From this, the amount of change in the accumulated water pressure is measured.
Thereafter, the stored water amount calculation means 92 obtains the amount of change in the water level of the stored water pressure from the measured amount of change in the stored water pressure. Then, the calculated amount of change in the stored water level is applied to the calibration curve stored in advance in the calibration curve storage unit 93 to calculate the second variation when only the second measurement pipe line 823 is communicated. . The calculated second change value is stored in a memory (not shown).

  Next, the individual excrement amount calculation means 94 calculates the amount of urine and the specific gravity of the urine. In the individual excrement amount calculation means 94, when the values obtained so far (the specific gravity of the stool, the first change amount, the second change amount) are applied to the formula obtained based on the measurement principle described later, And the specific gravity of the urine is calculated.

  The measurement result (calculated urine volume and specific gravity of the urine) is displayed on the display unit provided on the remote control 52 for the excrement amount measuring device so that the user can confirm, as in the above-described operation, or in the toilet. The information is printed on a printer provided or transmitted to a personal computer or printer used by a medical staff together with personal information and measurement time.

The toilet flushing and the formation of the measurement start water level (Y) are similar to the above-described operation.
When the measurement start water level (Y) is formed and the accumulated water pressure before the user excretes is measured by the pressure sensor 842, “preparing” displayed on the display unit provided on the remote control 52 for the excrement amount measuring device. “” Changes to “measurable” and the measurement of the amount of excreta is completed.

  When urine and urine are excreted, the individual excreta amount calculating means 94 calculates the amount of stool and urine using a formula obtained based on the measurement principle described later, but only the urine was excreted. In some cases, the urine volume and the specific gravity of the urine are calculated.

  In addition, when the user excretes only urine, the specific gravity of stool can be calculated in the same manner as when only urine is excreted. However, since the specific gravity of stool is more likely to change than the specific gravity of urine, care must be taken when using the calculated specific gravity of stool.

  In this embodiment, the water level at standby is the measurement start water level (Y), so that there is no risk of the water drainage (breaking) occurring due to pressure fluctuations generated in the drain pipe during standby. The predetermined amount, also referred to as the sealing depth, from the sealing level (X) is set to 50 mm or more and 100 mm or less as indicated in the Building Ordinance for Construction Law. By securing a predetermined amount of sealing water, it is not necessary to pay attention to sanitary problems such as odors in the sewage pipe leaking into the toilet or sanitary pests entering the toilet. When a user uses only as a toilet, it should wait at the above-mentioned overflow water level (H), but when the thing which does not perform excretion amount measurement and the thing which does not perform are mixed, it is a measurement start water level (Y). It is necessary to wait so that the user does not need to wait for the water level to move.

  Next, the measurement principle in the present invention will be described with reference to FIG. The measurement principle described below is based on new knowledge found by a preliminary experiment by the present inventor.

  FIG. 4 is a schematic diagram showing a state after the user excretes stool and urine. FIG. 4A shows a state in which the first measurement pipeline in the present invention is communicated and the second measurement pipeline is closed, and FIG. 4B is a diagram in which the second measurement pipeline in the present invention is communicated. In this state, the first measurement pipe line is closed. The specific gravity of urine and urine is both greater than 1.

  Those having a specific gravity greater than 1 sink to the bottom of the bowl, and therefore, when only the first measurement pipe 81 is communicated with only when the second measurement pipe 82 is communicated, it is measured by the accumulated water pressure measuring means 84. Different values will be different. Here, the amount of urine is S (ml), the amount of stool is D (ml), the specific gravity of urine is a, the specific gravity of stool is b, and the first change amount when only the first measurement line is connected is A (Ml), B (ml) is the second change amount when only the second measurement pipe line is communicated.

As shown in FIG. 4A, in the state where the first measurement pipe 81 is opened and the accumulated water 23 is communicated and the second measurement pipe 82 is closed by the measurement pipe switching means 83, Only water level changes are measured.
Therefore, the water level in the measurement pipe 843 connected to the stored water pressure measuring means 84 is the same as the stored water level in the stored water 23 (S1 = T1).
Therefore, the first change amount A calculated from the change amount of the stored water pressure measured by the stored water pressure measuring means 84 is:
S + D = A (Formula 1)
It can be expressed as.
The amount of change in the accumulated water pressure measured by the accumulated water pressure measuring means 84 is measured by the accumulated water pressure measuring means 84 before the user's excretion from the accumulated water pressure PS1 measured by the accumulated water pressure measuring means 84 after the user's excretion. The value obtained by subtracting the accumulated water pressure PY.

Further, as shown in FIG. 4B, when the second measurement pipe 82 is opened by the measurement pipe switching means 83 to communicate with the stored water and the first measurement pipe 81 is closed, the stored water pressure The measurement pipe 843 connected to the measurement means 84 and the bowl 22 containing excreta having a specific gravity greater than 1 constitute a U-shaped pipe water path via the second measurement pipe 82. That is, it is affected by the specific gravity of stool and urine. Therefore, the water level in the measurement pipe 843 having a relatively small specific gravity is higher than that in the state of FIG. 4A (S1 <S2), and the stored water level in the bowl 22 having a large relative specific gravity is It becomes lower than the state of 4 (a) (T1> T2). Therefore, the water level in the measurement pipe line 843 is larger than the stored water level in the bowl 22 (S2> T2).
Therefore, the second change amount B calculated from the change amount of the stored water pressure measured by the stored water pressure measuring means 84 is:
aS + bD = B (Formula 2)
It can be expressed as.
The amount of change in the accumulated water pressure measured by the accumulated water pressure measuring means 84 is measured by the accumulated water pressure measuring means 84 before the user's excretion from the accumulated water pressure PS2 measured by the accumulated water pressure measuring means 84 after the user's excretion. The value obtained by subtracting the accumulated water pressure PY.

  If the specific gravity a and the specific gravity b of stool registered in the specific gravity registration means are put into the simultaneous equations consisting of (Equation 1) and (Equation 2), and the simultaneous equations are solved, the stool volume S (ml) and the stool The quantity D (ml) can be calculated individually.

For example, if a user excretes stool in the shape of a manure and urine having a specific gravity of 1.0, the specific gravity registration means includes 1.1 as the specific gravity of the stool and 1.0 as the specific gravity of the urine. Is registered. When only the first measurement pipe is communicated, the first change calculated from the change in the stored water pressure measured by the stored water pressure measuring means is A (ml) = 300, only the second measurement pipe If the second change amount calculated from the change amount of the accumulated water pressure measured by the accumulated water pressure measuring means is B (ml) = 320, the equation 1 and the equation 2 ), The stool volume S (ml) = 100 and the stool volume D (ml) = 200.
As another example, if the user designates that only urine is excreted, there is no amount of stool, so the specific gravity of 0 is registered in the specific gravity registration means 91 as the specific gravity of the stool.
When only the first measurement pipe is communicated, the first change calculated from the change in the stored water pressure measured by the stored water pressure measuring means is A (ml) = 100, only the second measurement pipe If the second change amount calculated from the change amount of the accumulated water pressure measured by the accumulated water pressure measurement means is B (ml) = 120, the equations (1) and (2) ), The urine amount S (ml) = 100 and the specific gravity of the urine a = 1.2 are calculated.
In this way, not only the amount of excrement but also the specific gravity of excrement can be calculated.

  Further, in this embodiment, the measurement line switching means for selectively selecting and communicating the first measurement line and the second measurement line is provided, and one pressure sensor is used as the accumulated water pressure in the present invention. Although the measurement means is provided, two measurement pipes provided with pressure sensors may be provided without providing the measurement pipe switching means, and may be configured to communicate with each of the first measurement pipe and the second measurement pipe. In that case, it is necessary to perform output calibration based on the atmospheric pressure for each pressure sensor and to obtain a relational expression between the pressure and the amount of stored water. It becomes possible.

  As described above, according to the excrement amount measuring apparatus of the present invention, individual calculation of the amount of stool and the amount of stool can be realized by simply excreting the urinal as usual for both men and women. Thereby, while a user's shame is eliminated, the effort of a medical worker can be reduced. In addition, the maintenance of the condition of the sterile room can be promoted, and the prognosis management of the patient can be improved.
