Description

  The present invention relates to collecting the excrement of a subject in a ball surface of a toilet used for excretion and obtaining excretion information such as the amount, composition, and property thereof, and is generated in a sewage pipe connected to the toilet. The present invention relates to a toilet with an excrement information measuring function that prevents the influence of unstable factors such as pressure fluctuations from affecting the accuracy of excrement information measurement, and also ensures sufficient operational reliability as a toilet. . Particularly preferably, it is used for measuring the amount and components of excreted urine.

  Hereinafter, measurement related to urination, which is an example of excrement information measurement, will be described.

Conventional toilets with excrement measurement functions include a method of receiving excreted urine in a container and measuring the volume thereof (see, for example, Patent Document 1).
When using a container of such a limited size for a urine collector, it is difficult to collect all urine in the urine collector, especially if there are individual differences in the direction of urination as seen in women. However, there was a problem that accurate urine volume measurement could not be performed.

In some cases, the toilet ball portion is used as a urine collector to solve the above-described problem and improve the collection rate of urine (see, for example, Patent Documents 2 and 3).
All of these have reservoir water that also functions as a seal to prevent backflow of odors from the sewage pipe to which the toilet is connected, and measure the amount of urine excreted by measuring the change in the amount of water. It is what.

  However, in actual sewage pipes, pressure fluctuations occur in the sewage pipes due to water flow caused by drainage of other water-related equipment, and the stored water level surface moves. There was a thing.

  In addition, in the case of the device of Patent Document 2, it is necessary to prevent urine from flowing out to the sewage side due to an increase due to urination of stored water. For this reason, the trap portion of the toilet is expanded and contracted. Leakage of stored water from the expansion / contraction part was likely to occur, and it was difficult to satisfy the toilet characteristics of long-term use.

  In the case of the apparatus of Patent Document 3, the water level of the toilet bowl part is lowered by communicating the ball part and the sewage pipe at the time of measurement. In this case, too, the water channel fixing part is exposed in the sewage discharge path. There was a possibility that the performance as a toilet such as clogging may be deteriorated.

Furthermore, there is a method in which opening / closing means such as a flap valve is arranged in the drainage channel as a configuration of the toilet itself (see, for example, Patent Document 4).
According to this method, fluctuations in the sewage pressure are not transmitted to the stored water, so there is no adverse effect on the measurement. However, if the opening / closing means is arranged in this way, in the unlikely event that a malfunction occurs, it takes time for maintenance such as repair, or prevents water from being charged in charging parts such as motors and wiring connection parts that drive the opening / closing means. Therefore, it was necessary to consider their arrangement and structure.

Japanese Patent Application Laid-Open No. 07-259166 Japanese Patent Laid-Open No. 08-299348 JP-A-10-027883 Japanese Patent Laid-Open No. 11-061951

  The present invention has been made to solve the above problems, and the object of the present invention is to generally use a toilet in a toilet that excretes, regardless of gender, such as the amount of urine, the rate of excretion, and properties. In addition to measuring excrement information with high accuracy, an object of the present invention is to obtain an excrement information measuring toilet that ensures operation reliability such as excrement transport as a toilet that is a sanitary equipment.

In order to achieve the above object, according to the first aspect of the present invention, the trap structure that seals against the sewage pipe, the stored water reservoir formed by the trap structure, and the information on the excrement of the user In the excrement information measuring toilet having the excrement measuring means for measuring

After the user's excrement excreted and stored in the second ball part is discharged to the first ball part through the communication path by supplying cleaning water from the second ball water supply path, It is characterized by discharging to the sewage pipe by supplying cleaning water from the ball section water supply passage.

  As a result, even if a pressure fluctuation caused by water flow from other equipment generated in the sewage pipe is generated, it can be prevented from being transmitted to the urine volume measuring toilet of the present invention. Stable operation as a toilet bowl can be controlled by separately controlling the cleaning and discharging operation of the first ball part where the excrement falls and the discharge operation of the waste from the first ball part to the sewage pipe. It was also possible.

  According to a second aspect of the present invention, when discharging the user's excrement excreted in the first nibol part to a sewage pipe, the cleaning water is supplied from the second ball water supply passage to the nibale part. Then, the communication path is opened, and then the cleaning water is supplied from the first ball section water supply path to the first ball section in this order.

  As a result, the washing and discharging process of the first ball part where the user's excrement falls and the stable discharging process of the excrement from the first ball part to the sewage pipe are carried out in a series of operations, and the excrement is collected. Because it is discharged into the sewage pipe, the operation reliability of the toilet can be improved.

  According to a third aspect of the present invention, the excrement measuring means has a water level measuring means for detecting a change in the water level of the second ball surface that has received the urination of the excreted user, and is measured. It is characterized by obtaining urination information by changing the water level.

As a result, even a woman who has individual differences in the direction of urination can collect all urine as a measurement target, and can obtain highly reliable urination information regardless of gender.
It was possible to improve the operational reliability of the communication passage opening and closing means.

Further, according to the invention of claim 4, wherein said level measuring means includes a guide passage for measuring a water level change of the first Niboru surface, the opening of the pressure guide path is disposed in the communicating passage opening and closing means It is characterized by being.

  Therefore, even if foreign matter such as excreted stool or thrown toilet paper enters through the opening and becomes clogged or the area of the impulse line is narrowed, it is removed together with the communication passage opening / closing means and removed by washing, etc. As a result, the productivity of the entire apparatus can be improved, and maintenance work can be facilitated.

According to a fifth aspect of the present invention, the pressure guiding path allows piping cleaning water to be washed to clean the inside of the pressure guiding path when supplying cleaning water from at least the second ball water supply path to the second ball surface. It is characterized by.

  As a result, water is passed each time the toilet is cleaned to clean the pressure line piping, so it can be removed even if excrement enters the pressure line pipe, and long-term reliability of function and performance is ensured. It was possible to ensure the sex.

According to a sixth aspect of the present invention, the trap structure portion is provided with a jet spout for generating a siphon phenomenon.

  This makes it possible to more stably discharge excrement into the sewage pipe and improve the operation reliability as a toilet.

According to a seventh aspect of the present invention, the communication path opening / closing means has a charging mechanism portion that is driven by electricity, and the charging mechanism portion has a waterproof structure.

  This prevents the charging member such as the electric motor constituting the charging mechanism from getting wet even during normal filth discharge operation and sewage overflow operation due to clogging of piping, etc., and the communication path including the safety aspect The operational reliability of the opening / closing means can be improved.

According to an eighth aspect of the present invention, the charging mechanism portion of the communication path opening / closing means is disposed above the overflow surface of the second ball portion.

As a result, the water level does not rise to the position of a charging member such as an electric motor even during normal filth discharge operation and sewage overflow operation due to clogging of piping, etc., and safety is improved. According to the invention of claim 9, which has a accumulated water in the toilet use waiting for the first Niboru surface, after a predetermined time has elapsed, or accumulated water level by the water level measurement results of the water level measuring means is subtracted When this is detected, replenishment water is supplied.

  As a result, a user who does not perform measurement can be used as a normal toilet without waiting time, and it is possible to eliminate the possibility that the excrement adheres to the toilet drying surface and increases the cleaning load.

  According to the present invention, since it has various functions as a toilet and is configured to perform various measurements on excrement while blocking the influence in the adjacent sewage pipe, it is connected to the water and sewage system. Highly accurate measurement is possible while ensuring operational reliability as a sanitary equipment.

The embodiment of the present invention will be described in detail below.
The following is described by taking urine volume measurement as an example of excrement information, but the present invention describes qualitative / quantitative values / properties of specific components such as glucose contained in urine, occult blood contained in stool The qualitative / quantitative value / normality of the specific component, and the like, and the qualitative / quantitative value / normality of the specific component such as occult blood contained in the vomit are applicable to various measurements performed by collecting the specimen sample in the toilet.

  FIG. 1 is a perspective view showing a first embodiment of an excrement information measuring toilet that measures urine volume as excrement information according to the present invention. The functional unit case 3 is transparent so that the internal unit can be confirmed, and only the outline is left.

  Inside the functional unit unit case 3, a control unit 5 for controlling the urination information measuring toilet and a low tank 10-1 for storing washing water to be supplied to the Western-style toilet 1 are arranged. Further, metal fittings for branching city water to the raw tank 10-1 and the urination information measurement function unit, a power outlet, a ground connection member, and the like are also arranged inside. A part of the back portion of the Western-style toilet 1 is caused to interfere with the functional unit case 3, thereby preventing an increase in the area occupied by the depth of the urine information measuring toilet in the toilet booth. The power supply / control wiring connected to each part for realizing the urination information measurement function including the above-described water supply and power supply connecting member and the communication path opening / closing mechanism 6 from the control unit 5 will also be arranged inside. It prevents the appearance from deteriorating and the cleaning performance from deteriorating.

  As a material for the functional unit case 3, a wooden laminated material is recommended from the viewpoint of appearance quality and cost for household use, in which cleaning with a wiping cloth is assumed. When installing in public toilets such as hospitals, fire-resistant materials such as PVC steel sheets should be selected in consideration of mischief by users. When improvement in noise resistance or the like is required, noise absorbing means for preventing radio noise from entering may be arranged inside the functional case. In addition, adoption of a door mechanism considering maintenance and storage as appropriate is also an arbitrary design matter.

  The toilet unit 1 includes a Western-style toilet 10, a mechanism unit case 3 including a urine volume measuring unit 4 and a control unit 5, and a communication path opening / closing mechanism 6 attached to a rim surface 14 which is an upper surface of the Western-style toilet 10. It is constituted by. The communication path opening / closing mechanism 6 may be integrally formed with a base plate for assembling a toilet seat / toilet lid (not shown) to the toilet 10. Above the western-style toilet 10, a second ball portion 12 that is opened in a bowl shape for receiving the excrement of the user is formed. The second ball portion 12 stores second ball portion water 13-2 that receives the excrement of the user. Further, a toilet seat unit (not shown) is disposed so as to abut on the rim surface 14 of the Western-style toilet 10.

  A remote control device (not shown) is provided on the wall. The urine component measurement result is output to a terminal device such as a printer or a display panel (not shown). The measurement results can be used not only by the user as personal ecological information but also by medical staff who have read the measurement results in medical practice. The urine component measurement results are not only output on paper, but also information transmission using wireless or wired communication lines, or output using an external storage medium such as an RFID tag, ID card, magnetic card, or semiconductor memory. Or an internal storage medium such as a semiconductor memory or a hard disk for storing information inside the apparatus.

  The detailed configuration of the first embodiment of the present invention will be described below with reference to FIGS.

  FIG. 2 is a system configuration diagram showing the configuration of the first embodiment, and FIG. 3 is a block diagram thereof.

  A first ball portion 11 communicating with a sewage pipe (not shown) via a trap portion 15 is formed below the second ball portion 12 described above. The first ball part 11 stores a first ball part stored water 13-1 as sealed water that prevents backflow such as foul odor from the sewage pipe. In addition, a communication path through which excrement passes is configured between the first ball part 11 and the second ball part 12 disposed above the first ball part 11, and a communication path opening / closing means 20 for excrement is provided between the communication path. Has been placed. The communication passage opening / closing means 20 uses a mechanism using a flap valve in this example, but has a weir structure in which the overflow surface moves up and down so that overflow can be prevented until the urine amount reaches a predetermined amount. It is also possible to take other open / close structures.

  The communication path opening / closing means 20 is driven by an electric motor and is disposed outside the toilet opening 10-2 of the Western-style toilet 10, so that the appearance quality is improved by making it difficult for the user to see directly, and directly There is no risk of stool sticking.

  The excrement stored in the first ball part 11 is sent out to the sewage pipe together with the accumulated water by a washing phenomenon caused by water supply from the raw tank 10-1 or a siphon phenomenon generated in the trap part 15.

  In the vicinity of the lower end of the second ball portion 12, a pressure guiding path 42 that guides the water level of the second ball portion stored water 13-2 to the pressure sensor 43 as a pressure value prevents clogging due to stool or the like, or narrowing due to intrusion of foreign matter. Therefore, it opens toward the communication path opening / closing means 20 side.

  The electric motor and the pressure sensor of the communication path opening / closing mechanism 6 perform a sequence operation by the control / display unit 70. The pressure sensor is connected to the urination information calculation unit 71, and calculates the urine volume from the amount of accumulated water before and after the start of urination, and the urine flow rate from the differential coefficient per time.

  The first ball portion 11 is separate from the second ball portion 12 that measures the amount of urine excreted by a change in the water level, and the both constitute a western-style toilet 10 in combination. The first ball portion 11 also serves as a sewage pipe connection portion, and it is recommended that the first ball portion 11 be formed of a resin such as vinyl chloride in terms of freedom of shape realization. In addition, the second ball portion 12 that is directly excreted by the user and cleaned with a detergent or a scrubber is integrally formed with a pottery that is an outer shell, and is connected by a packing member 7. Since the outer part of the pottery part is an integral structure, filth dirt does not enter the gap part and can be used in a sanitary manner.

  Since the urine can be collected by the entire second ball portion 12, even if there is an individual difference in the direction of urination as seen in women, the whole urine can be collected reliably. An application in which a part of urine is used for measuring the concentration of a specific component in urine and sent to another measurement medium / measurement means via the pressure guiding path 42 is also conceivable.

  In addition, the second ball portion stored water 13-2 stored in the second ball portion 12 that receives the excreta is quickly and entirely transferred to the first ball portion stored water by operating the communication path opening / closing means 20. It is also possible to expose to the ball surface of the second ball portion 12 by discharging to 13-1. Therefore, the excrement information measurement toilet according to the present invention is used not only for urine volume measurement and urine sample collection for determining the metabolic state of the whole body in a medical institution such as a hospital, but also for the second ball portion 12 that does not collect stool. Therefore, a stool sample can be easily collected and used as a sample for various medical tests.

  The city water guided to the stop cock 17 is diverted to the low tank 10-1 for supplying the cleaning water to the first ball part 11 and the second ball part 12 side by the branch fitting 17-1. A ball tap 10-3 is built in the low tank 10-1. The city water supplied to the low tank 10-1 is adjusted to accumulate a predetermined amount via the ball tap 10-3, and is guided to the first ball portion 11 via the drain valve 10-4 driven by the electric motor 10-5. .

  One of the city water branched to the second ball portion 12 side is led to the on-off valve 19, and the other is led to the on-off valve 33. The water guided to the on-off valve 19 side passes through the backflow prevention means 32 such as a vacuum breaker and an air gap, and is further diverted into two directions by the branch fitting 17-2, one of which forms the outlet of the second ball portion water supply passage 91. The rim water spouting nozzle 8 is supplied to the second ball portion 12 and used for cleaning the ball surface.

  The other branched by the branch metal fitting 17-2 is connected to a pressure guiding path 42 for measuring the water level via the electrolyzed water generating means 37 and the on-off valve 33.

  When the second ball portion water is supplied from the rim water spouting nozzle 8 to the second ball portion 12 via the second ball portion water supply passage 91 when cleaning the toilet bowl, the on-off valve 33 is opened each time water is supplied. In addition, the on-off valve 35 is closed to protect the pressure sensor 43 and the inside of the pressure guiding path 42 can be cleaned by guiding city water to the pressure guiding path 42. Further, when the water pressure by the water level head of the stored water is measured, the on-off valve 33 is closed and the on-off valve 35 is opened so that the flow path between the pressure sensor 43 and the second ball portion 12 is communicated.

In addition, an electrolyzed water generating means 37 is disposed in the flow path connected to the pressure guiding path 42, and the inside of the pressure guiding path 42 is sterilized hypochlorous acid generated by electrolyzing city water containing chlorine. Ion prevents the blockage from occurring due to the propagation of urine and bacteria caused by the environment in the toilet.
Even if the device is installed so as to supply metal ions such as silver ions having antibacterial properties instead of the electrolyzed water generating means 37, the concept of preventing clogging by suppressing the propagation of various bacteria in the pipeline is the same. is there.

  In this way, the water supplied from the rim water spouting nozzle 8 for cleaning the second ball portion 12 and the water that has cleaned the pressure guiding path 42 become the second ball portion water storage 13-2, and are connected together with the excrement. After passing through the passage opening / closing means 20 and discharged to the first ball portion water 13-1 of the first ball portion 11, the water is discharged from the raw tank 10-1 to the sewage pipe 18.

  The operation in the case of performing urination information measurement which is one of the excretion information using the first embodiment of the excretion information measurement toilet of the present invention having the above-described configuration will be described below.

(1) When the user measures excrement information When the user performs a measurement preparation operation, the communication path opening / closing means 20 is opened, and the second ball portion stored water 13-2 stored in the second ball portion is It falls on the first ball part 11. Next, the opening / closing valve 33 is closed and the opening / closing valve 35 is opened, and a space between the second ball portion 12 and the pressure sensor 43 is prepared as a pressure guiding path 42 for detecting the water level. In this state, the communication path opening / closing means 20 is closed and waits for the user to urinate. At this time, the measurement origin of the pressure sensor 43 is calibrated using the state before urination in which no urine is present in the second ball portion 12 as a measurement reference. Next, when the user urinates, urine is collected in the second ball portion 12, and the water level is measured by the pressure sensor 43 through the pressure guiding path 42. In this way, since the sensor calibrates the origin for each measurement and the water level at which urine is excreted is measured by the pressure sensor 43, the measurement reproducibility of each measurement is not affected by changes in ambient temperature or the like. high.

  In this case, if the water level before urination is the water level Y, the water level after urination is the water level Z, and the water level during urination is the water level X, the second ball portion 12 is empty at the water level Y. The amount of accumulated water in the second ball portion 12 is the amount of urination at that time. Even if a pressure fluctuation occurs due to a drainage flow caused by other equipment or the like in the sewage pipe during the measurement, the communication path opening / closing means 20 is closed at this time, so that the second ball portion reservoir 13-2 No influence is transmitted to the pressure sensor 43 that measures the water level of the water, and the total urine output can be measured by measuring the water level X with high accuracy, and by measuring the water level Z. The functional relationship between the stored water level and the amount of stored water in the second ball portion 12 is not only set as a design value, but when manufacturing / construction errors are assumed, quantitative water supply can be performed during construction or periodic inspections. It may be set as a calibration curve or a control table by measuring the water level change behavior with respect to.

  The change in the amount of accumulated water per unit time depends on the rate at which urine is excreted and is called the urine flow rate or urine flow rate in the medical field. The urine flow rate or urine flow rate may be calculated by The calculation of the urine flow rate or the urine flow rate can also be performed by measuring the time required to increase the unit pressure. In addition, the time from the start of urination until the urine flow rate or urine flow rate reaches the maximum value is also stored, and the resulting urine volume, urination time, maximum urine flow rate (maximum urine flow rate), Estimating the possibility of urinary illness of the user based on the comparison of information such as the time to reach the maximum urine flow rate (maximum urine flow rate) and the evaluation table of each user stored in the database in advance Can also be done.

Next, when the user finishes the measurement operation and performs the toilet flushing operation, the on-off valve 19 is first opened, and water is supplied to the second ball portion 12 where urination has been performed and the pressure guiding path 42 where the water level has been measured. Done. Next, the communication passage opening / closing means 20 is opened, and after the second ball portion stored water 13-2 mixed with excreted urine and washing water is dropped into the stored water 13 of the first ball portion 11, the low tank 10- The water supply from 1 is guided to the first ball part 11 through a drain valve 10-4 driven by an actuator such as an electric motor (not shown).
The water led from the low tank 10-1 through the drain valve 10-4 is discharged together with excrement in a sewage pipe (not shown) due to the momentum of the water and the siphon phenomenon that occurs when the top of the trap 15 is filled with water. Will be sent to. In the present example, the first ball part 11 is an example in which the first ball part 11 is integrally formed up to the drain socket part connected to the sewage pipe. However, the first ball part 11 may be combined separately.

  After the discharge to the sewage pipe is completed, the refill water supplied from the low tank 10-1 via the drain valve 10-4 is guided to the first ball part 11, and the first ball part stored water 13-1 again overflows the trap part 15. It will return to the running water level. The city water is branched by the branch metal fitting 17-1, one of which is supplied to the low tank 10-1 through the ball tap 10-3, and when the amount of water that can be discharged with high reliability can be collected, Stopped. The other is supplied from the rim water spouting nozzle 8 to the second ball portion via the on-off valve 19, and the second ball portion reservoir 13-2 is formed again.

  (2) When the user does not measure excrement information and uses it only as a normal toilet.

When the user does not perform the measurement preparation operation, the communication path opening / closing means 20 remains closed and operates as a stool mode for excreting large and small stools. When the user defecates in this state, since the stool falls directly into the second ball portion reservoir 13-2 at the discharge water level W, there is little possibility that dirt is attached to the second ball surface 12-1. . In accordance with the user's toilet cleaning operation, the rim water spouting nozzle 8 provided in the second ball portion 12 is guided in a tangential direction with respect to the elliptical second ball portion 12 and turns on the second ball surface 12-1. . The swirling flow swirls the adhering stool while also swirling the second ball portion stored water 13-2. Next, the communication path opening / closing means 20 is opened at a predetermined timing, thereby dropping the second ball part stored water 13-2 mixed with excrement into the first ball part stored water 13-1. Next, the water introduced from the raw tank 10-1 is stored in a first ball portion reservoir that is mixed with excreta in a sewage pipe (not shown) due to the momentum of the water and the siphon phenomenon that occurs when the top of the trap portion 15 is filled with water. Water 13-1 is discharged.
After the completion of discharge, the refill water supplied from the low tank 10-1 via the drain valve 10-4 is guided to the first ball part 11, and the first ball part water 13-1 is again at the overflow water level of the trap part 15. Will return. Moreover, the 2nd ball part stored water 13-2 is formed again by supplying water to the 2nd ball part 12 from the rim water discharge nozzle 8. FIG.

  In particular, since the stool may be accidentally excreted and adhered to the second ball surface 12-1 when collecting urine, it is possible to prevent contamination by arranging an adhesion prevention means such as Cefiontect (trademark). it can. In addition, excrement easily flows down into the second ball portion stored water 13 by using a cleaning method using a swirling flow having a high effect of removing filth, which is also referred to as Tornado Cleaning (trademark).

  FIG. 4 is an operation flowchart of the first embodiment of the present invention, and a more detailed operation will be described below based on this flowchart.

S101 is a step in which the waiting urine measurement toilet detects the proximity of the user. The first ball part is full of water up to the overflow water level of the trap part. Further, the communication path opening / closing means between the first ball part and the second ball part is closed, and water is formed inside the second ball part so that dirt due to defecation is difficult to adhere. The conduit of the pressure guiding pipe that connects the pressure sensor that measures the water level and the second ball part that measures the water level is full of water, but the on-off valve in the middle is closed, so that dirt including excrement and detergent is present. It is designed not to diffuse or enter the sensor section.
S102 is a step of determining whether or not the user has performed a predetermined preparation operation such as pressing a preparation switch for measurement or holding a tag or ID card for personal authentication. If the user sits without operating the preparation switch, the urine volume is not measured, but it is determined as a defecation use and the process proceeds to step S201. Note that the determination as to whether or not the measurement is used may be made by providing a dedicated SW for display such as “measurement” and “stool”.

If it is determined in step S102 that the user has indicated an intention to measure urine volume, the communication path opening / closing means is opened in step S103, and the second ball portion stored water 13-2 is discharged to the first ball portion.
In step S104, the origin of the sensor output for measuring the pressure according to the water level of the second ball where the user urinates is calibrated. At this time, since the communication path opening / closing means is open, the water level is 0, the pressure is recognized as the origin, and the pressure sensor is calibrated to the atmospheric pressure at that time. Even if there is a drift in the absolute value of the pressure sensor due to the influence of the ambient temperature, it is canceled in step S104.
S105 is a step of driving the closing / opening means 20 to be closed in order to prevent urine excreted by the second ball from falling on the first ball. When the operation of the communication passage opening / closing means 20 is completed, preparation for measurement of a change in water level accompanying urination is completed, and therefore, in step S106, the control display unit 70 displays that the preparation for urine volume measurement is completed for the user. In consideration of user convenience, if the time required from S101 to S106 is within 10 seconds, the user can be prevented from feeling that he / she has to wait for urination.
In step S107, the user urinates toward the second ball portion 12. While female urination is performed in a sitting position, male urination can prevent splattering in the sitting position. However, when measuring the urinary flow rate, it is recommended that men be in a standing position where their abdominal muscles work easily. In the case of men, the urination posture may be selected according to the purpose of measurement. S108 is a step in which urine is aspirated and measured toward a predetermined sensing means in order to measure the concentration of a specific component contained in urine. When only the urine volume is required, it is not necessary. However, when it is necessary to measure the concentration of a specific component using a urine sample, a separate urine collecting means is provided to collect urine directly, or the urine stored in the second ball part 12 is collected. What is necessary is just to employ | adopt suitably.
When urination ends, the user performs an end operation in step S109. A predetermined operation such as pressing an end switch or holding a personal authentication tag or ID card is performed. S110 is a step of measuring the water level of the second ball portion stored water 13-2 by a pressure value.
S111 is a step of converting the water level into urine volume. Since the amount of stored water before urination is 0, the amount of stored water represented by the measured water level is directly calculated as the amount of urine. At the same time, a derivative per hour may be calculated to calculate a change in urine flow rate over time. The relationship between the water level and the amount of stored water is set as a design value, and when construction and dimensional variations are included, the water level for each specified amount of water is learned, and a calibration curve and comparison table showing the relationship between the water level and the amount of stored water are set. May be.
S112 is a step of determining whether or not normal measurement has been performed in order to disclose the urine volume calculated from the water level change to the user. For example, when a stool-like solid volume with stool falls at the same time as urination, discontinuities occur in the water level change behavior or a large undulation occurs. In the case of normal measurement, the measurement result is displayed as it is in step S113. If there is a concern about abnormal measurement such as simultaneous excretion of stool during urination, the urine volume measurement accuracy is determined in step S114. A warning is added to the measurement result to indicate that there is any doubt.

When a suction operation is performed to measure a specific component in urine, a sample as a specimen is used to prevent diagnostic errors for items that cannot be measured if there is a concern about stool contamination and for instrument maintenance. You may perform the operation | movement which stops the suction | inhalation of urine.
S115 is a step in which the user who has finished defecation performs a toilet cleaning operation. In step S116, the second ball portion 12 is cleaned by rim water discharge, and the pressure guiding path 42 in which the water level is measured is cleaned. After completion of the cleaning for a predetermined time, S117 is a step of driving the communication path opening / closing means in order to drop the urine of the second ball part into the accumulated water of the first ball part. When the discharge from the second ball portion to the first ball portion is completed, the communication path opening / closing means is closed in step S118 in order to prevent dirt from entering the second ball portion due to the discharged splash of excrement. When the closing of the communication passage opening / closing means is completed, water is supplied from the first ball portion water supply passage to the first ball portion in step S119, and the first ball portion is washed and discharged to the sewer pipe.
