Description

The present invention relates to a biological information measuring device that measures biological information using the difference in water level before and after excretion of a Western-style toilet bowl.

In addition to measuring the change in water level due to excretion, the conventional biological information measuring device using a toilet bowl changes the water level due to the spraying of sodium hypochlorite, which takes into consideration the stains and antibacterial properties that occur in the bowl over time. A coping operation is performed by measuring (see, for example, Patent Document 1).
In such a case, although the biometric information measuring device can cope with the water level change carried out as its own operation, it cannot cope with the water level change that may occur accidentally. Specifically, when the water is generally mistaken for a toilet bowl and the water is dumped, the measurement reference water level fluctuates unexpectedly, resulting in a decrease in measurement accuracy.

It is also possible that the water level in the toilet bowl fluctuates due to clogging of the toilet bowl by a foreign substance and the water level is increasing. In response to such a problem, there is an attempt to detect clogging by using the cleaning operation of the toilet bowl (for example, Patent Document 2).

Japanese Unexamined Patent Publication No. 2018-062773 Japanese Patent No. 5605765

However, in Patent Document 2, clogging can be detected only after the cleaning operation is performed. Therefore, in the measurement of information related to biological information such as excretion, it is necessary to take measures before excretion and reproduce the reference water level.

The present invention has been made to solve the above problems, and an object of the present invention is to suppress an accidental decrease in measurement accuracy.

According to the invention of claim 1 in order to achieve the above object, it is a biometric information measuring device for measuring biometric information of a user, and is connected to a bowl for excretion by the user and the bowl. Discharge the wash water into the bowl at least with a stool having a trap that forms a pool of water in the bowl and when the stool is in use or when the stool is not used for a predetermined time or longer. The human body is provided with a cleaning function unit, at least one water level measuring means for measuring the water level in the bowl, and a pooled water discharging means for discharging the pooled water in the bowl and forming the pooled water to a predetermined water level. In the case of non-detection, the water level measuring means is operated at predetermined time intervals, and when the water level in the bowl exceeds the predetermined water level, the stored water discharge means is operated to determine the overflow water level or less of the trap. Set to water level.
In the present invention configured as described above, even if the water level of the accumulated water changes accidentally, the water level measuring means is operated at predetermined intervals to measure whether or not the water level is a predetermined water level (reference water level), and a predetermined water level is determined. When the water level is not high, the stored water discharge means can be activated to reset the water level to a predetermined level, and the biological information can be measured accurately.

Further, according to the invention of claim 2, the water level measuring means measures the static pressure of the accumulated water or is based on the capacitance.
In the present invention configured as described above, the water level can be reliably measured, and the biological information can be measured accurately by operating the stored water discharge means.

Further, according to the invention of claim 3, the biological information measurement according to claim 1 or 2, wherein when it is detected that the water level is not a predetermined level after the reservoir discharge means is operated, a notification is given. It is a device.
According to the present invention configured in this way, if the stored water discharge means is activated but does not return to the predetermined water level, it is determined that the cause is clogging or the like, and the person in charge of maintenance performs maintenance. It can be notified and returned to a predetermined water level, and biological information can be measured with high accuracy.

According to the present invention, there is an effect that it is possible to suppress a decrease in measurement accuracy that occurs accidentally.

(About the configuration of the biological information measuring device 1)
FIG. 1 is a perspective view illustrating a toilet room in which the biological information measuring device according to the embodiment is installed. FIG. 2 is a perspective view illustrating a part of the biological information measuring device according to the embodiment.
As shown in FIG. 1, the biological information measuring device 1 includes a toilet bowl 2, a sanitary cleaning device 3 (cleaning function unit), and a function unit 5.
The toilet bowl 2 is, for example, a floor-standing Western-style toilet bowl (Western-style stool).
A cabinet 18 is provided behind the toilet bowl 2. Further, the cabinet 18 is provided with a backrest portion 7 having a cushioning property. The backrest portion 7 is designed for elderly people and sick patients who have difficulty in maintaining a trunk posture, and a type with a stool lid (not shown) may be selected.

The functional unit 5 is provided inside the cabinet 18. The functional unit 5 has a function of measuring biological information such as the amount of urine excreted by the user (subject) and the excretion rate of urine.

The sanitary cleaning device 3 is provided on the toilet bowl 2. The sanitary cleaning device 3 has a casing 400 and a toilet seat 200. The sanitary cleaning device 3 may further have a toilet lid.
The toilet seat 200 is pivotally supported with respect to the casing 400 so as to be openable and closable. The casing 400 has a built-in local cleaning function for cleaning the local area of the user sitting on the toilet seat 200.

As shown in FIG. 1, a barcode reading device 10 and an operation unit 11 are installed on the wall surface of the toilet room. The operation unit 11 includes a remote controller 12 for measuring biological information, a sanitary cleaning device 3, and a remote controller 14 for a toilet bowl. The remote controller 12 is provided with a measurement start switch for instructing the start of measurement of urination information, a urination end switch for instructing the end of urination, and the like.

A data output device 16 is provided on the cabinet 18. The data output device 16 is a printer that prints the measurement results and the like of the biological information measuring device 1.

FIG. 2 is a system configuration diagram illustrating the biological information measuring device according to the embodiment. In FIG. 2, the sanitary cleaning device 3 and the like are omitted for convenience of explanation.
The toilet bowl 2 has a bowl 22 for excretion by the user and a trap 24. The trap 24 is connected below the bowl 22. The toilet bowl 2 is connected to the drainage pipe 26 via the drainage socket 25. A pool of water 23 is formed in the bowl 22 by a trap 24. The pooled water 23 has a role of sealing water that shuts off between the drainage pipe 26 and the bowl 22.

Further, the biological information measuring device 1 has a rim spout 215 arranged on the rim of the toilet bowl 2 and a Zet spout 541 (washing water supply means) arranged below the trap 24. After excreting in the toilet bowl 2, the user discharges the accumulated water 23 mixed with excrement, and presses the switch of the operation unit 11 instructing the discharge operation in order to prepare for measurement described later. When the switch of the operation unit 11 is pressed, the operation unit 11 transmits a cleaning signal to the control unit. Upon receiving the cleaning signal, the control unit discharges water (washing water) from the water pipe from the rim spout 215 and the Z spout 541. When the Z spout 541 discharges water into the trap 24, a siphon phenomenon occurs in the trap 24. Due to this siphon phenomenon, a negative pressure is generated in the drainage pipe 26. As a result, the accumulated water 23 in the bowl 22 is discharged to the drainage pipe 26.

The water supplied from the water pipe is branched into the washing water water supply pipe 212 and the urine volume measuring unit water supply pipe 217 by the branch fitting 211.
The water supplied to the wash water supply line 212 is supplied to the rim water supply line 214 and the Zet water supply line 216 by opening the stopcock 210 and the three-way valve 213. The water supplied to the rim water supply line 214 is guided to the rim spout 215 and discharged from the rim spout 215. The water supplied to the Zet water supply pipe 216 is guided to the Zet spout 541 via the branching tool 542, and is discharged from the Zet spout 541.

The water supplied from the branch fitting 211 to the water supply pipe line 217 of the urine volume measuring unit is guided to the functional unit 5. The functional unit 5 includes a water replenishment tank 61, a water replenishment pump 62 (water level setting means), a trap tank 551, a drain pipe pressure measurement sensor 561, a calibration pump 811, a water level forming pipe 511, and a pressure sensor 512 (water level measurement). Means) and a plurality of on-off valves (on-off valves 521, 522, 524, 525, 611). The operation of each of these elements is controlled by the control unit. Each of the plurality of on-off valves is a solenoid valve that opens and closes by electric power.

The water from the water pipe is supplied to the refill tank 61 by opening the on-off valve 611. The refill tank 61 has a float switch 612. When the amount of water in the refill tank 61 reaches a predetermined amount, the float switch 612 detects water and the water supply to the refill tank 61 is stopped. In the unlikely event that a malfunction occurs when the water supply to the refill tank 61 is stopped, water is discharged to the overflow pipe 64.

The water discharged to the overflow pipe 64 is guided to the trap tank 551. The trap tank 551 is a drain tank that traps excess water such as overflow water generated by the operation of the functional unit 5. The water in the trap tank 551 is discharged to the drainage pipe 26 via the drainage pipe connecting pipe line 562.

The trap 24 and the bowl 22 are connected to the pipeline 543 (measurement pipeline) via the Zet spout 541 and the branching tool 542. The pipeline 543 is connected to the functional unit 5 in order to measure the water level of the pooled water 23 in the bowl 22. An on-off valve 544 is provided in the middle of the pipeline 543. By closing the on-off valve 544, the connection between the toilet bowl 2 and the functional unit 5 can be released. As a result, the toilet bowl 2 can be used as a normal sanitary device that does not measure urination information. Further, when the toilet bowl 2 or the functional unit 5 fails, for example, the failed toilet bowl 2 or the functional unit 5 can be easily replaced.

The pipeline 543 is connected to the water level forming pipe 511 via an on-off valve 524 and a pressure sensor 512. The water level forming pipe 511 is a vertical pipe portion extending in the vertical direction and having a predetermined height. Further, one end of the water level forming pipe 511 is connected to the trap tank 551 and is open to the atmosphere.

When the on-off valve 544, the on-off valve 521, and the on-off valve 524 are opened, the water level forming pipe 511 communicates with the bowl 22. As a result, a U-shaped pipe whose both ends are open to the atmosphere is formed by the bowl 22, the water level forming pipe 511, and the pipe 543. Therefore, the water level in the water level forming pipe 511 and the water level of the pool water 23 in the bowl 22 become the same. The pressure sensor 512 (water level sensor) measures the pressure (head pressure) of water in the water level forming pipe 511 and outputs the measurement result (voltage value) to the control unit.

(About the measurement method of biological information)
Next, a method of measuring biological information (urination information) in the biological information measuring device 1 will be described.
The control unit stores in advance the relational expression between the water level and the amount of water in the pool water 23 in the bowl 22. The amount of water in the pool 23 can be calculated from this relational expression and the water level measured by the pressure sensor 512. The amount of urine can be calculated from the change in the amount of water in the pool 23.

First, the derivation of the relational expression between the stored water 23 in the bowl 22 and the amount of water will be described.
When the biometric information measuring device 1 is installed in the toilet room, the installer of the biometric information measuring device 1 calculates the above-mentioned relational expression and sets it in the control unit.
First, the on-off valve 544, 521, 525, 524 is opened. Next, the water level in the bowl 22 is set to the overflow water level H by spouting water from the rim spout 215 and the Z spout 541. The overflow water level H is the limit water level at which the water in the trap 24 overflows from the weir portion 22a.

Next, the calibration pump 811 is driven. The calibration pump 811 discharges the stored water 23 in the bowl 22 toward the trap tank 551 in units of, for example, 230 ml (mL). That is, the accumulated water 23 in the bowl 22 is removed by the calibration pump 40, for example, by 230 mL each. Therefore, the water level in the bowl 22 decreases each time the calibration pump 811 is driven. Then, each time the calibration pump 811 is driven, the pressure of water in the water level forming pipe 511 is measured by the pressure sensor 512. Since the on-off valves 521 and 524 are in the open state, the water level in the water level forming pipe 511 is the same as the water level in the bowl 22.

In this way, a certain amount of water is removed from the bowl 22, and the water level reduced at that time is measured by the pressure sensor 512. As a result, the relational expression between the output value of the pressure sensor 512 (water level sensor) and the amount of water in the reservoir 23 in the bowl 22 in the toilet bowl 2, that is, the relational expression between the water level and the amount of water in the reservoir 23 in the bowl 22 Can be calculated. The builder sets the calculated relational expression in the control unit. The method of calculating the relational expression between the water level of the pooled water 23 in the bowl 22 and the amount of water may be a manual method that does not use the calibration pump 811. For example, a method in which the operator removes the accumulated water from the overflow water level H in a fixed amount or a method in which the accumulated water is added in a fixed amount from the ruptured water level L may be used.

Next, the measurement operation of the biological information measuring device 1 will be described.
In this example, the water level of the pool water 23 in the bowl 22 during the measurement standby is assumed to be a predetermined water level Y (hereinafter, may be referred to as a measurement start water level Y). The measurement start water level Y is a water level higher than the rupture water level L by a predetermined amount. The measurement start water level Y is, for example, a water level 50 to 55 mm (mm) higher than the ruptured water level L. Further, the measurement start water level Y is, for example, a water level 20 to 30 mm lower than the overflow water level H. The measurement start water level Y is preferably 50 to 100 mm (mm) for the purpose of maintaining a sanitary environment in the drainage pipe and the toilet room.

As will be described later, the water level when the measurement is actually started may be different from the predetermined water level Y (measurement start water level Y).

In the biological information measuring device 1, the water level forming tube 511 is in a substantially full state while waiting for measurement. This is because the patient who is the user may have a disease that makes it difficult to tolerate urination. Since the water level forming pipe 511 is full during standby, the time for filling the water level forming pipe 511 to be full in preparation for measurement can be omitted, and the measurement operation can be performed immediately.

At the time of measurement, the head pressure of the water level forming pipe 511 in a full state is measured by the pressure sensor 512 according to the measurement start operation of the user. The output value of the pressure sensor 512 is compared with the output value in a full water state stored in advance by the control unit 405. This makes it possible to calibrate the relational expression between the water level and the amount of water stored in the control unit in consideration of environmental fluctuation factors such as atmospheric pressure and air temperature.

The measurement is started when the user enters the toilet room while waiting for the measurement and sends a measurement start signal to the control unit. For example, the user has a bar code tag, and when the bar code tag is held by the bar code reading device 10, the bar code reading device 10 transmits a measurement start signal of urination information to the control unit.

Upon receiving the measurement start signal, the control unit opens the on-off valves 521 and 524. At this time, the water level in the water level forming pipe 511 becomes the same as the water level of the pool water 23 in the bowl 22. At this time, the water level of the pooled water 23 in the bowl 22 slightly rises from the measurement start water level Y. However, the amount of the pooled water 23 is sufficiently larger than the amount of water from the pipeline 543 to the water level forming pipe 511. Therefore, the amount of increase is very small, and the water level of the pool water 23 in the bowl 22 does not substantially change from the measurement start water level Y.

When the biological information measuring device 1 is in a state where urination information can be measured, the liquid crystal screen 12a provided on the remote controller 12 displays "Please urinate". After that, the user performs a urination operation on the bowl 22. When the user's urination operation is completed, the water level of the pool water 23 in the bowl 22 rises from the measurement start water level Y to the post-urination water level C. At the same time, the water level in the water level forming pipe 511 becomes the water level C after urination.

After that, the user transmits a measurement end signal to the control unit. For example, the measurement end signal can be transmitted by pressing the measurement end switch provided on the remote controller 12.

When the control unit receives the measurement end signal, the pressure sensor 512 measures the pressure in the water level forming pipe 511 and outputs the measurement result to the control unit according to the instruction of the control unit. The control unit calculates the amount of rising water in the bowl 22, that is, the amount of urine of the user, from the measurement result and the relational expression between the water level and the amount of water in the pool 23 in the bowl 22 stored in advance.

In addition, the control unit not only the user's urine volume, but also, for example, urination time (seconds), maximum urine flow rate (mL / second), average urine flow rate (mL / second), maximum urine flow rate arrival time ( Calculate urination information such as seconds) and hesitation time (seconds). The urination time is the time from the start of urine discharge to the bowl 22 to the end of urine discharge to the bowl 22. Urine flow rate is the amount of urine per unit time, that is, the rate of urination. The maximum urine flow rate is the maximum value of the urine flow rate. The average urine flow rate is the average value of the urine flow rate. The time to reach the maximum urine flow rate is the time from the start of urination to the maximum value of the urine flow rate. The hesitation time is the time from when "Please urinate" is displayed on the liquid crystal screen 12a until the start of urination. When the calculation of the urination information by the control unit is completed, the data output device 16 prints out the calculated urination information.

When the series of measurement operations is completed in the biological information measuring device 1, the toilet bowl is cleaned by, for example, the user pressing the cleaning switch 14a provided on the remote controller 14. As a result, the water level of the pooled water 23 in the bowl 22 is set to a predetermined water level Y (measurement start water level Y).

Specifically, first, the bowl 22 is washed by spouting water from the rim spout 215. Then, by the water spouting from the Z water spouting port 541, almost all the accumulated water 23 is discharged to the drainage pipe 26. After that, the pool water 23 is supplied to the bowl 22 until the rupture water level L is exceeded by the water discharged from the rim water discharge port 215.

Next, the on-off valve 524 and the on-off valve 525 are closed, and the on-off valve 521 and the on-off valve 522 are opened. As a result, the water refill tank 61 and the bowl 22 are communicated with each other by the refill pipe 63 and the pipe 543. In this state, the refill pump 62 (water level setting means) is operated to supply the water in the refill tank 61 from the Zet spout 541 to the bowl 22. The refill pump 62 adjusts the amount of water supplied so that the water level in the bowl 22 becomes the measurement start water level Y. As a result, the water level of the pooled water 23 in the bowl 22 becomes the measurement start water level Y.

After the measurement start water level Y is set, the on-off valves 521 and 525 are closed, and the on-off valves 522 and 524 are opened. In this state, the refill pump 62 is operated to guide the water in the refill tank 61 to the water level forming pipe 511, and the water level forming pipe 511 is made substantially full. Then, the biological information measuring device 1 returns to the standby state.

The drainage pipe pressure measurement sensor 561 measures the pressure due to the air in the trap tank 551, that is, the pressure due to the air in the drainage pipe 26, and outputs the measurement result (voltage value) to the control unit 405. Based on the measurement result of the drainage pipe pressure measurement sensor 561, the control unit 405 calibrates the relational expression between the water level and the amount of water in the pool 22 stored in advance, and executes the urination information measurement operation. As a result, even if positive pressure or negative pressure is generated in the drainage pipe 26 and the water level of the pooled water 23 in the bowl 22 fluctuates, the biological information measuring device 1 corrects the influence of the fluctuation and urinate information. The measurement operation can be performed.

An example of the case where the Zet spout 541 is used as the pooled water discharge means will be described with reference to FIG. FIG. 3 is a flowchart illustrating the operation of the biological information measuring device according to the embodiment. As shown in FIG. 3, in step S101, the time elapsed from the previous toilet bowl cleaning, that is, the setting of the measurement start water level is measured. The measurement start water level will be set according to the toilet bowl cleaning, but not only the supply of functional water that continues to increase over time, but also the accidental increase in water level due to accidental disposal of water into the toilet bowl is considered. Be done. In addition, the water level at which the accumulated water 23 is sucked may drop due to the generation of negative pressure in the drainage pipe due to the accidental fullness of the pipeline in the drainage pipe. If the specified time interval is exceeded, there is a possibility that an accidental water level change of a predetermined amount or more has occurred. Therefore, when the predetermined time interval is exceeded, the human body detecting means detects the human body in step S102. If there is human body detection, there is a possibility that the cleaner is cleaning with a rubber cup (trade name), and a pressure load that poses a risk of failure may be applied to the pressure sensor 512. Therefore, step S101 is performed. Return. If there is no human body detection, the water level is measured in step S103. The state of the water level is confirmed in step S104, and if there is no fluctuation in the water level other than the predetermined value, the state is measurable, so the process returns to step S101. On the contrary, when an excessive change in the water level is confirmed, it is necessary to reset the measurement start water level, so the process proceeds to step S110 for automatically starting the toilet bowl cleaning. In step S105, the human body detecting means detects the human body when the time elapsed from the previous cleaning of the toilet bowl, that is, the setting of the measurement start water level has not passed a predetermined value.
When the human body is detected, the sanitary cleaning device 3 then performs "pre-use watering" in step S106. The seating is confirmed in step S107, and if the seat is not seated, there is a possibility that the user is not the user but a cleaner, so the process returns to step S101. The user who needs measurement performs a urination operation after the measurement start operation (step S108), measures biological information related to urination (step S109), and manually performs the toilet bowl cleaning operation S110.

When the measurement of the urination information is completed, the toilet bowl is washed (step S110). As a result, the accumulated water 23 including urination in the bowl 22 is discharged to the drain pipe 26. Then, water is supplied from the rim spout 215 to the bowl 22 until the water level of the pool 23 of the bowl 22 exceeds the rupture water level L.

After that, the water level setting means (water replenishment pump 62) supplies the water in the refill tank 61 to the bowl 22 (step S111: measurement start water level creation step).

The water level of the reservoir 23 set by the water level setting means in step S111 may be the measurement start water level Y, but in this example, the water level is lower than the measurement start water level Y. After the accumulated water is discharged by the toilet bowl cleaning, the sanitary cleaning device 3 performs "device cleaning" and "watering after use", and the cleaning water is supplied into the bowl. Since the water level of the accumulated water 23 rises due to the washing water, the water level setting means forms a water level lower than the measurement start water level Y in step S111 after considering the amount of the washing water in advance. That is, the water level in the bowl 22 set by the water level setting means is determined according to the amount of washing water discharged into the bowl 22 by the sanitary cleaning device 3 after the stored water discharging means discharges the stored water.

In step S112, the sanitary cleaning device 3 performs "device cleaning". Further, in step S113, the sanitary cleaning device 3 carries out "watering after use". As a result, the water level of the reservoir 23 rises, and in step S111, a predetermined water level Y (measurement start water level Y) is formed.

After a predetermined time (for example, 8 hours) has elapsed (step S111: Y), the sanitary cleaning device 3 performs periodic "device cleaning" and "watering after use" (periodic mist) (steps S112, S113). Is repeated in order to ensure the hygiene of the bowl 22, but the details are omitted because it is different from the gist of the present invention.

As described above, in this example, when the water level in the bowl 22 is periodically measured by the water level measuring means, there is an accidental water level change behavior, and the measurement result exceeds the predetermined water level, the accumulated water is stored. Discharge (washing the toilet bowl) is performed and the measurement start water level Y is formed again. As a result, it is possible to suppress a decrease in the measured amount of urine even when the washing water is periodically supplied from the sanitary washing device 3. Further, by using the Zet spout 541 for cleaning the toilet bowl as the accumulated water discharge means, it is possible to suppress the complicated configuration.

FIG. 4 is a perspective view showing a connected state of the drainage socket and the toilet bowl according to the embodiment. FIG. 5 is a perspective view showing an inspection port of the drainage socket according to the embodiment. The maintenance when the foreign matter is thrown in and the foreign matter is clogged in the drainage socket 25 will be described in detail with reference to FIGS. 4 and 5.
A drainage socket 25 is connected to the drainage pipe 26 of the building. By inserting the toilet bowl 2, the drainage socket 25 is designed to discharge the accumulated water mixed with excrement to the drainage pipe. A sanitary cleaning device 3 is arranged above the toilet bowl 2, and a drainage socket 25 is arranged to communicate the drainage pipe 26 of the building and the discharge port of the toilet bowl 2. Although not shown, the functional unit 5 for measuring the water level of the pool 23 is arranged on the back back of the toilet bowl 2. The functional unit 5 can be pulled out during maintenance, and the maintenance person can visually recognize the drainage socket 25 from the side. The drainage socket 25 has an opening 251 so that it can be opened from the side, so that a foreign matter erroneously taken out from the bowl 22 can be taken out.
Since it is not necessary to remove everything attached to the drainage pipe 26 of the building in order to take out foreign matter and then re-install it, consideration is given so that the time required for maintenance can be omitted. It is also preferable to form the cover 252 covering the opening 251 with a metal plate from the viewpoint of complying with the Fire Service Act.

Further effects and variations can be easily derived by those skilled in the art. For this reason, the broader aspects of the invention are not limited to the particular details and representative embodiments expressed and described as described above. Therefore, various modifications can be made without departing from the spirit or scope of the general concept of the invention as defined by the appended claims and their equivalents.
