Description

  The present invention relates to a biological information measuring toilet that can measure various biological information such as the amount of urination of a subject using a Western-style toilet.

  As a conventional biological information measuring toilet, the amount of change in the stored water level when urinating into a Western-style toilet is measured, and biological information such as urine volume is stored using the calibration relationship between the stored water level and the stored water level. There is something to measure. In this case, the pressure in the sewage pipe is measured and converted to a state without pressure fluctuation in order to avoid the measurement value being affected by fluctuations in the stored water level caused by pressure fluctuations generated in the sewage pipe. (For example, refer to Patent Document 1).

  Further, unlike the method for measuring the amount of change in the stored water level as described above, there is a method for measuring biological information by measuring the temperature change of the stored water when urinating into a Western-style toilet (for example, Patent Document 2). reference.). In addition, unlike these measurement methods, there are also methods that measure biological information using specific component concentrations contained in urine excreted in a Western-style toilet (see, for example, Patent Document 3).

International Publication No. 2004/113630 Pamphlet JP 2003-302397 A JP 2004-279219 A

  In the case of a biological information measuring toilet (toilet unit) described in Patent Document 1, various biological information such as urine output can be measured using a Western-style toilet, but sewage pressure fluctuations appearing as environmental factors at the construction site are Since the correction algorithm is set assuming the impact of the sewage pressure, the sewer pressure wave with an unexpected frequency is transmitted, or the reservoir has a frequency that resonates. If sewage pressure waves are transmitted, measurement accuracy may be reduced, or measurement may become impossible.

  Further, in the biological information measuring toilet described in Patent Document 2, since the urine excreted by the Western-style toilet stagnates the accumulated water over the overflow water level of the trap, the overflow portion can be considered to be only the retained water. Even if the amount of urination is the same, there is a difference in measurement accuracy between when urinated at a flow rate and when urinated at a high urine flow rate where urine is expected to be mixed in the overflow area. There is. Furthermore, in the case of this biological information measuring toilet, since the temperature of the excreted raw urine is assumed to be a predetermined body temperature, changes in body temperature and individual differences in body temperature may directly become measurement errors.

  On the other hand, in the living body information measuring toilet described in Patent Document 3 (toilet unit using a urine information measuring device), as described above, the accumulated water exceeds the overflow water level of the trap due to excreted urine. The urination is the same when the urine is discharged with a low urine flow rate, which can be considered to be only the stored water, and when the urine is discharged with a high urine flow rate, which is expected to contain urine in the overflow portion. Even the quantity may cause a difference in measurement accuracy.

  The problem to be solved by the present invention is to provide a biological information measuring toilet capable of measuring various biological information such as the amount of urination with high accuracy without being affected by environmental factors at the construction site.

And the operation / display unit 20 disposed on the side wall surface of the western toilet 11. The Western toilet 11 includes a toilet seat 15 for a user to sit on, a toilet lid 17 that covers the ball 16 and the toilet seat 15 so as to be opened and closed, a urine physical property measuring means 18 having a urine collector 18a and a urine collection arm 18b, and a sanitary washing device. 23. The operation / display unit 20 includes a remote controller 19 for operating a sanitary washing device 23 provided in the western-style toilet 11, a remote controller 21 for causing the urination information measuring means 12 to function, and urination information measurement data for printing. And a printer 22. The urine information measuring means 12 is provided with a stored water property estimating means 41, and the control means 13 is provided with a calibration curve storage means 38, a urine information calculating means 39, and an information storage means 40.

  As shown in FIGS. 2 and 3, the western toilet 11 includes a ball 16 that receives a user's urine, a rim water spouting nozzle 24 a that constitutes a ball cleaning means for cleaning the inside of the ball 16, and excrement in the ball 16. Zet water discharge nozzle 24b as a siphon phenomenon generating means for discharging the water containing sewage toward the sewage pipe 35, the drain socket 9 for communicating the ball 16 and the sewage pipe 35, and the reservoir for sealing the sewage pipe 35. A trap 25 provided in the middle of the discharge pipe for storing the water W1. In addition, the stored water amount setting means 8 that sets the pre-urinated water W1 to a predetermined predetermined amount of water, the urine physical property measuring means 18 that measures the specific physical property value of the urine excreted by the user, and the above-mentioned stored water W1. And stored water physical property measuring means 7 for measuring specific physical property values. The stored water property measuring means 7 is connected to the stored water property estimating means 41 for estimating a steady value based on the fluctuation value with time.

  In the water channel switching means 4 arranged downstream of the water stop cock 3, the water is branched into a water supply path to the rim water discharge nozzle 24a and a water supply path to the jet water discharge nozzle 24b, and between the water channel switching means 4 and the rim water discharge nozzle 24a. The ball water supply valve 8a is arranged on the front. Further, a sewage drain valve 8b and a trap 5 are disposed in a drain path 26 branched from between the water channel switching means 4 and the ball water supply valve 8a, and a downstream end portion of the drain path 26 is communicated with the drain socket 9. . Further, a sewage pressure fluctuation measuring means 6 for measuring the pressure in the space 2 between the stored water W1 and the sewage pipe 35 is provided. The stored water amount setting means 8 includes a ball water supply valve 8 a that supplies and stops water to the ball 16, and a sewage drain valve 8 b that opens and closes the drain passage 26. Moreover, the ball water supply valve 8a and the sewage drain valve 8b are utilized as the stored water stirring means 48 which supplies water to the stored water W1 and stirs the stored water W1.

  As shown in FIG. 3, the biological information measuring toilet 10 of the present embodiment is configured to measure urine physical properties if the user urinates to the ball 16 in which the stored water W1 having a predetermined stored water amount set by the stored water amount setting means 8 is stored. The means 18 measures the specific physical property value of urine, and the stored water physical property measuring means 7 measures the specific physical property value of the stored water W1 from the start of urination to the end of urination, and then the predetermined stored water amount and the urine physical property measuring means 18 Biological information including at least urine volume can be measured based on the measured value and the measured value of the stored water physical property measuring means 7. In this case, the predetermined amount of stored water, the measured value of the urine physical property measuring means 18 and the measured value of the stored water physical property measuring means 7 are not affected by the pressure fluctuation generated in the sewage pipe 35 to which the Western-style toilet 11 is connected. Since it is a behavioral medium, various biological information such as the amount of urination can be measured with high accuracy without being affected by environmental factors at the construction site of the western toilet 11.

  Here, a procedure for measuring urine volume by the biological information measuring toilet 10 will be described with reference to FIG. As shown in FIG. 3, when the western-style toilet 11 is in a standby state, the accumulated water W1 in the ball 16 is set to a predetermined accumulated water amount set in advance by the accumulated water amount setting means 8, so that the accumulated water level W1L. Is lower than the overflow water level H of the trap 25. In the state shown in FIG. 3, when the user sits on the Western-style toilet 11, the urine collection arm 18b rotates and the urine collection device 18a is set in the urination route, and then urinates into the ball 16, a part of the urine is collected. The remaining urine flows into the stored water W1 while being collected by the vessel 18a. At this time, the stored water level W1L of the stored water W1 is lower than the overflow water level H and is set in consideration of the change in the water level due to fluctuations in the sewage pressure. Therefore, even if urine flows into the stored water W1, the trap 25 The sewage pipe 35 will not overflow.

  Thereafter, the specific physical property value of the urine collected in the urine collecting device 18a is measured by the urine physical property measuring means 18, and the specific physical property value of the stored water W1 into which the urine flows is measured by the stored water physical property measuring means 7. Then, the measured value of the urine physical property measuring means 18 at the time of the predetermined accumulated water and the measured value of the accumulated water measuring means 7 from the start of urination to the end of urination are transmitted to the control means 13 of the urination information measuring means 12. The urination information calculation means 39 calculates urination information including at least the urine output based on these measured values and a predetermined amount of water stored in the predetermined water W1, and the measurement value is displayed on the operation / display unit 20. It is displayed and stored in the information storage means 40. At this time, when a predetermined output operation is performed on the remote controller 21, a piece of paper on which the measured value is printed is output from the printer 22.

  As a means for measuring the specific physical property value of the urine excreted by the user, as shown in FIG. 3, the ball 16 of the western toilet 11 is formed instead of the urine physical property measuring means 18 having the urine collection device 18a and the urine collection arm 18b. It is also possible to measure by the urine physical property measuring means 28 arranged in the partition wall 11a and calculate urination information including at least the amount of urination based on this measurement value.

  By the way, although the specific physical property value of the stored water W1 changes due to urine contamination, a considerable time is required until the specific physical property value of the entire stored water W1 becomes a uniform specific physical property value due to natural diffusion of urine. When the physical property value is measured after the specific physical property value changes or stabilizes, it takes time until the urination information is disclosed to the user. Therefore, in order to calculate urination information in a short time, pay attention to the fluctuation tendency of the predetermined physical property value change behavior of the stored water, and compensate for the fluctuation from the urination start to the urination end with the functional relationship, and estimate the stable value May be. FIG. 4 is a graph showing an example of an actual measurement value related to the conductivity variation of stored water. For example, the conductivity at the time of stabilization is estimated from the function regression relationship from the start of the change in conductivity to the end of the urination operation. Become.

  In another embodiment, it is also possible to shorten the time during which the predetermined physical property value is changed and stabilized by stirring the stored water. In the case of using a general pulsator or the like as a stirring method, excrement (especially stool) is also discharged, and there is a concern that operation reliability may be lowered due to adhesion of dirt or the like to the pulsator. Therefore, the present applicant confirmed a beneficial effect by stirring the bubbles by discharging bubbles into the ball and utilizing the burst energy.

Further, a beneficial effect was confirmed by stirring a small amount of water discharged so as not to overflow to the ball 16 from the rim water discharging nozzle 24a. FIG. 5 is a graph showing a method for calculating the water discharge amount from the rim water discharge nozzle 24a that can be used for stirring. When the amount of retained water QH at the overflow water level H (example: 3500 mL) and the amount of retained water QL at the measurement start water level W1L (example: 2100 mL), the maximum urine volume measurement range QM ′ when there is no sewage pressure fluctuation (example: 1400 mL) ) Is represented by (Formula 1).
QM ′ = QH−QL (Formula 1)

When pressure fluctuations occur in the sewage pipe 35, the maximum urine volume measurement range QM changes due to suction by negative pressure and rocking back by positive pressure unloading. When actually measured with the toilet bowl C950B, the relation of (Expression 2) and (Expression 3) was obtained with respect to the sewage pressure fluctuation P (mmAqa).
In case of positive pressure QM = QM′−40P (Formula 2)
In the case of negative pressure QM = QM '+ 40P (Formula 3)

If it is desired to measure up to a urine volume N (eg, 800 mL) as a product specification, the water discharge amount QT used for stirring can be expressed by (Equation 4).
QT <QM'-N (Formula 4)

  In the case described above, when the sewage pressure fluctuation P is 10 mmAqa, the water discharge amount QT that can be used for stirring is 200 mL. Since the water channel switching means 4 is a valve that allows water to flow through a large flow rate, the operation variation of the on-off valve body is large, and it is difficult to supply a small amount of water discharge. Therefore, rapid pipe switching is realized by the ball water supply valve 8a and the sewage drain valve 8b, and the accumulated water W1 can be agitated by supplying a small amount of highly accurate water discharge into the ball 16.

  FIG. 6 is a graph showing an example of the change in conductivity when stirring by water discharge is performed, and it can be seen that the conductivity is stable in a short time. In general, since fluctuations in the sewage pressure are accompanied by pulsation, even if stirring is performed with a water discharge amount in consideration of prevention of overflow, overflow may occur as an example. In that case, since the conductivity peak value decreases due to overflow, the maximum value is used as an alternative value of the stable value.

Here, the concept of using the conductivity as the specific property value of urine used in the present invention and calculating the urine volume as a representative value will be described in detail. The mass of excreted urine is M1 (g), and the conductivity is C1 (mS / cm). The mass of the stored water before urination is M2 (g), and the conductivity is C2 (mS / cm). Let M3 (g) be the mass of water charged for stirring. The mass of the stored water after urination is M (g) and the conductivity is C (mS / cm). Since conductivity can be considered as an alternative value for the concentration of electrolyte contained in urine, the relationship that the amount of electrolyte is constant before and after urination is used.
M1 × C1 + M2 × C2 = (M1 + M2 + M3) × C (Formula 5)

Here, when expanding for M1,
M1 = {M2 * (C-C2) + M3 * C} / (C1-C) (Formula 6)
Since the density of urine can be considered to be 1 g / mL as with water, the urine volume N is
N = {QL × (C−C2) + QT × C} / (C1-C) (Formula 7)
Can be calculated by Note that the estimated value described above may be used as the value of C. Even using temperature and specific component concentrations can be formulated in a similar way. In addition, consideration may be given so that the measured value can be matched by introducing a coefficient into each term in accordance with the experimental value.

  When the urine volume measurement is completed and a predetermined toilet cleaning operation is performed, the inner surface of the ball 16 is washed with water discharged from the rim water discharging nozzle 24a, and then water discharged from the jet water discharging nozzle 24b toward the trap 25 is performed. A phenomenon occurs, and the urine mixed water W1 in the ball 16 is discharged and the toilet bowl is washed. When the toilet flushing of the stored water W1 is completed, water is supplied from the rim water discharge nozzle 24a into the ball 16, but the stored water amount setting means 8 opens the sewage drain valve 8b and closes the ball water supply valve 8a. Therefore, the stored water W1 in the ball 16 is set to a predetermined stored water amount determined in advance by the stored water amount setting means 8, and the stored water level W1L is set lower than the overflow water level H of the trap 25, and again enters a standby state. Return.

  Since the water channel switching means 4 is a valve that allows water to flow through a large flow rate, the operation variation of the on-off valve body is large, and it is difficult to supply a predetermined amount of stored water. Therefore, in this embodiment, rapid pipe switching is realized by the ball water supply valve 8a and the sewage drain valve 8b, so that a predetermined amount of stored water can be supplied into the ball 16 with high accuracy. Further, by providing a trap 5 between the drainage socket 9 communicating with the sewage drain valve 8b and the sewage pipe 35, odors and sanitary pests in the sewage drain pipe are prevented from entering the toilet.

  Next, the operation of the biological information measuring toilet 10 of the present embodiment will be described with reference to FIGS. 7 is a diagram showing an operation sequence of the biological information measuring toilet 10 shown in FIG. 1, and FIG. 8 is a flowchart showing an operation of the biological information measuring toilet 10 shown in FIG.

  As shown in FIGS. 7 and 8, when the user enters the toilet in which the biological information measuring toilet 10 is placed (step 60), the user's human body is detected (step 61), and the display unit of the remote controller 21 displays “ “Preparing” is displayed. Thereafter, when a preparatory operation is performed on the remote controller 21 (step 62), the urine physical property measuring means 18 and the stored water physical property measuring means 7 are activated (step 63). As the preparation operation, there are a user's personal authentication operation and an activation trigger input operation of the measuring means, and various methods such as switch operation, fingerprint authentication, ID card insertion, and ID tag holding are assumed. When the preparation operation of each physical property measuring means is completed, the remote control 21 is notified of the completion of the preparation (step 64). Therefore, when the user undresses and sits on the toilet seat 15, a seating detection means (not shown) detects it. The display on the remote controller 21 is “measuring”. Thereafter, the user urinates toward the ball 16 (step 65). In the case of men, urination may be performed in a standing posture.

  A part of the urine excreted in the ball 16 is collected in the urine collecting device 18a, and the remaining urine flows into the stored water W1, but the specific physical property value of the urine collected in the urine collecting device 18a is the urine physical property measuring means. The specific physical property value of the stored water W1 into which urine has flowed is measured by the stored water property measuring means 7 (step 66). When the urination is finished (step 67) and the user performs the urination end operation on the remote controller 21 (step 68), the display on the remote controller 21 becomes "preparing" again, and the stored water stirring means 48 is activated. The agitation water discharge amount calculation is executed (step 69), the sewage drain valve 8b is closed (step 70), the ball water supply valve 8a is opened (step 71), and the water channel switching means 4 starts the rim side water supply (step 71). Step 72), stir water agitation is performed.

  When the rim side water supply is performed for a predetermined time (step 73), the sewage drain valve 8b is opened (step 74), the ball water supply valve is closed (step 75), and the water channel switching means 4 stops the water supply (step 76). . Excess water that is discharged from the water channel switching means 4 and does not need to be put into the ball 16 is discharged to the sewage pipe 35 via the sewage drain valve 8b. In addition, although the example using the method of speeding up the stabilization of the specific physical property value of the stored water by agitation has been described here, the stable value is predicted using the specific physical property value fluctuation state from the urination start to the urination end operation. It may be a method.

  Then, the stored water property estimating means 41 is operated to estimate the stored water property (step 77), the urination information calculating means 39 is operated to calculate the urine information (step 78), and the operation / display unit 20 is operated. Urination information is displayed (step 79). Thereafter, the sewage drain valve 8b is closed (step 80), the ball water supply valve 8a is opened (step 81), and the water channel switching means 4 starts the rim side water supply (step 82). When the rim side water supply is performed for a predetermined time (step 83), the sewage drain valve 8b is opened (step 84), the ball water supply valve 8a is closed (step 85), and the water channel switching means 4 stops the water supply (step 86). ). The operations from step 80 to step 86 are for preventing the dirt on the inner surface of the ball 16 due to defecation or stabilizing the toilet cleaning operation thereafter by returning the accumulated water level to the overflow water level H. However, it is not essential in the present invention. Depending on the shape of the toilet bowl and the toilet bowl washing sequence, it may be unnecessary.

  Next, when a predetermined toilet cleaning operation is performed (step 87), the sewage drain valve 8b is closed (step 88), the ball water supply valve 8a is opened (step 89), and the water channel switching means 4 is the inner surface of the ball 16 by the rim side water supply. Starts cleaning (step 90). When the rim side water supply is performed for a predetermined time (step 91), the water channel switching means 4 is switched to the jet side water supply (step 92). Zet-side water supply is performed for a predetermined time with respect to the trap 25, a siphon phenomenon occurs, and the excreta together with the stored water is discharged toward the sewage pipe (step 93).

  When the discharge is completed, the water channel switching means 4 switches to the rim side water supply again (step 94). When the rim side water supply is performed for a predetermined time (step 95), the sewage drain valve 8b is opened (step 96), the ball water supply valve 8a is closed (step 97), and the water channel switching means 4 stops the water supply. As a result, a certain amount of the stored water W1 is stored in the trap 25, and the normal standby state is restored. Such a series of operations are automatically performed, and when the user performs a toilet cleaning operation, the human body is not detected (step 99). Therefore, the user can freely leave the toilet (step 100). ).

  As described above, the biological information measuring toilet 10 is based on at least a predetermined amount of water stored in the ball 16, a measured value of the urine physical property measuring unit 18, and a measured value of the stored water physical property measuring unit 7. Biological information including the amount of urination can be measured. These measured values are change behavior media that are not affected by pressure fluctuations generated in the sewage pipe 35 (see FIG. 2) to which the western toilet 11 is connected. Various biological information such as the amount of urination can be measured with high accuracy without being influenced by the above.
