Hereinafter, embodiments of the biological information measuring apparatus disclosed in the present application will be described in detail with reference to the accompanying drawings. The present invention is not limited to the embodiments shown below.

The configuration of the biological information measuring device 1 according to the embodiment will be described with reference to FIGS. 1 to 3. FIG. 1 is a schematic perspective view showing a biological information measuring device 1 according to an embodiment.

As shown in FIG. 1, the biological information measuring device 1 is integrally incorporated into a Western-style toilet bowl (hereinafter referred to as "toilet bowl") 4 having a normal toilet bowl function such as a toilet bowl cleaning function and a toilet bowl 4. A sanitary cleaning device 7, a cabinet 18 installed behind the toilet bowl 4, an operation in which the user (also referred to as a subject) instructs various operations, and a wall for displaying the obtained measurement results and the like. It is composed of an operation / display unit 70 used when performing an operation provided in the above, an operation including a part of excreted urine directly collected, and the like.

The toilet bowl 4 is made of pottery, and a resin toilet seat 171 is rotatably attached to the upper part of the bowl. In this embodiment, an example in which a commonly adopted stool lid is omitted is shown. For example, when used in a medical institution, it is considered that the action performed to rotate the toilet lid is a burden for the patient with a physical illness, and conversely, the upper body of the patient is affected. A backrest 172 is installed in the cabinet 18 in consideration of support.

Inside the cabinet 18, the water level of the pooled water changes in order to measure urine volume information such as the amount of urine excreted by the subject into the toilet bowl 4 and the urine flow rate, which is the excretion rate per unit time. A urine volume measuring unit 50 provided with a mechanism unit or the like for measuring the urine volume measuring unit 50, and a urine volume measuring control unit 60 for performing operation control, information processing, etc. of the urine volume measuring unit 50 are housed. In addition, a urine component measuring unit or the like for measuring the concentration of a specific component in urine may be housed inside the cabinet 18 as needed. The size and shape of the cabinet 18 can be changed depending on the occupied volume of the item to be stored.

The operation / display unit 70 includes a remote controller 72 for measuring urination information and a remote controller 71 for operating the sanitary cleaning device, and a printer 73 for outputting urination information measurement results and the like is arranged above the cabinet 18. When considering the operability and visibility of the subject, it is recommended that the operation / display unit 70 and the remote controller 72 for measuring urination information be mounted on the wall, but the printer 73 is also mounted on the wall in consideration of the flow line of operation. It is also possible to.

The remote controller 72 is operated when a subject enters the tray and measures urination information, and is provided with a measurement start switch for instructing the start of measurement and a urination end switch for instructing the end of urination. Further, the remote controller 72 is provided with personal authentication means such as an individual switch, a means for reading an ID card and an ID tag, and an electronic data input / output device necessary for acquiring personal information such as a subject's measurement history. Has been done.

Although the measurement result is disclosed to the subject using the printer 73, it may be disclosed to the subject on the display unit of the remote controller 72. Further, when the present urination information measuring device is installed in a medical institution, it is conceivable that the nurse operates the remote controller 72 at a predetermined time to extract the data of a plurality of subjects from the printer 73.

The operation at the time of construction or maintenance is switched and set by performing the operation of a predetermined procedure on the switch of the remote controller 71 or the remote controller 72. As a method, since it is a switch that is not normally used, one switch is used for a plurality of purposes by opening the cover to expose the operation switch or pressing a predetermined switch for a long time.

As an act performed only at the time of construction or maintenance, the case where a predetermined value necessary for correcting the calibration relationship between the accumulated water level and the accumulated water amount shown in the present invention is input as a calibration value is applicable. In this case, the measured value of the urine flow rate is input, or the inclination information of the floor on which the urination information measuring device is installed is input. Notification of the need for update or calibration, which is an issue in the present application, and work related to update or calibration as a response are performed by a maintenance person (for example, a medical institution in which the biological information measuring device 1 is installed) for the remote controller 72. The person in charge of) will carry out the prescribed work.

The accumulated water in the toilet bowl 4 is discharged to the sewage drain port 16 via the drain socket 15. The sewage drainage port 16 is constructed by the construction work of a building, but its position accuracy requires a larger tolerance than that of a generally considered mechanic work. Since the position of the toilet bowl 4 is integrated with the sewage drainage port 16, it will move due to the variation in the position of the sewage drainage port 16.

The cabinet 18 is composed of a front plate 181 on the front surface, side plates 182 provided on the left and right sides, and a deck 183 that covers the ceiling. It indicates that the sizes of 181 and side plates 182 and deck 183 must be changed.

In this embodiment, in particular, a method of omitting the processing of the side plate 182, which has a long overall length and is difficult to process, is shown. First, the shape of the front plate 181 is fixed and integrated with the toilet bowl 4. The front plate 181 is integrated with a frame (not shown), and the side plates 182 and the deck 183 are attached to the frame. The depth direction dimension of the side plate 182 is formed so that the front plate 181 does not protrude from the front end of the side plate 182 even at the front tolerance upper limit position with respect to the positional deviation in the front-rear direction that occurs in the toilet bowl 4. Therefore, the toilet bowl 4 and the front plate 181 are only displaced in the front-rear direction with respect to the side plate 182.

A soft member having an R shape is provided at the front end (kiguchi) of the side plate 182 so that the subject's arm or elbow does not get injured even when it hits the front end (kiguchi). Assuming that it will be used in a medical institution, subjects with visual illness and subjects with poor eyesight due to old age are also assumed. Assuming the use of such a subject, if the front end (kiguchi) of the side plate 182 and the face material are of different colors, that is, black and white with contrast, the position of the toilet bowl 4 can be clearly determined. There is an advantage that it can be done.

FIG. 2 is a block diagram showing a configuration of the biological information measuring device 1 according to the embodiment. In FIG. 2, the solid line connecting each component indicates the water pipe, and the broken line indicates the connection route for information other than water.

The biological information measuring device 1 is roughly divided into a toilet bowl unit 3, a biological information measuring unit (urination information measuring unit) 5, and an operation / display unit 70. The reason why the toilet bowl unit 3 and the urination information measuring unit 5 are separately configured is that the manufacturing bases of the two are different and the contractors are different.

That is, both of them, which have been packed and transported at a plurality of manufacturing bases, are generally installed by the equipment supplier in charge of water supply and drainage and connected to the water and sewage system at the execution site, and the medical equipment is provided. After the contractor in charge of the construction work installs the urination information measuring unit 5 and connects the water supply / drainage pipe connecting the toilet bowl 3 and the urination information measuring unit 5 with the signal path to complete the urination information measuring device 1, urination is performed. The operation of the information measuring device 1 as a system can be confirmed. For this purpose, a linked operation control means 80 for coordinating the operation of the toilet bowl unit 3 and the operation of the urination information measuring unit 5 is provided straddling both of them.

The toilet bowl unit 3 is integrally incorporated in the toilet bowl 4 and the toilet bowl 4 having a function as a normal toilet bowl that receives the excrement and transports the excrement to the sewage pipe, and cleans the local part of the user after the toilet. It is composed of a sanitary cleaning device 7 provided with sanitary cleaning means 7a, and a toilet control unit 40 that controls the operation of the toilet bowl 4 and the sanitary cleaning device 7.

The toilet bowl 4 provides a bowl 20 for the subject to excrete, a trap 14 connected to the bowl 20 for storing the pool water 23 for water-sealing the communication with the sewage pipe, and water supply to the bowl 20. The trap 14 is connected to a sewage pipe port 16 that communicates with a sewage pipe provided in the toilet room via a drain socket 15.

Water is supplied from the external water supply source to the urination information measuring device 1 via the device water supply means 12, the sanitary cleaning means 7a, the rim water supply means 31 for supplying water to the bowl 20 of the toilet bowl 4, and the Zet. It is supplied by a water supply channel branched into a water supply means 32 and a water replenishment means 33.

The trap 14 is designed to discharge the stored water 23 to the drainage socket 15. When cleaning the toilet bowl, after cleaning the inner surface of the bowl 20 with the water supply of the rim water discharge means 32, the Zet water supply means 32 supplies water from the Zet spout 22 at a large water supply rate, so that the trap 14 becomes a full water level W and siphons. The phenomenon is induced, and the pooled water 23 is discharged to the sewage drainage port 16 through the drainage socket 15 to reach the empty water level X1.

After the accumulated water 23 is discharged by the siphon phenomenon described above, the normal toilet bowl returns to the overflow water level H described later by the water supply from the rim water supply means 31, but the urine information measurement toilet bowl of the present embodiment is excreted. It is necessary to temporarily collect the collected urine in the bowl 20 without letting it flow out to the drain pipe as it is. Therefore, water is supplied from the rim water supply means 31 only to a position exceeding the unsealed water level X2, which will be described later, and the measurement start water level Y whose water level is lower than the overflow water level H by a predetermined amount is set by the operation of the water replenishment means 33. I'm getting it.

Further, when the measurement start water level is formed, the water supply from the water replenishing means 33 is supplied with a water supply rate lower than that at the time of cleaning the toilet bowl, thereby improving the reproducibility of the measurement start water level Y. In this embodiment, water is supplied from the Zet spout 22 in order to prevent the water surface of the reservoir 23 from rippling. However, if the rim spout 21 and the bowl 20 are difficult to ruffle in shape, The water replenishment operation may be performed from the rim spout 21.

The toilet control unit 40 is provided with a water supply control means 41 for controlling the sanitary cleaning means 7a and the water supply operation of the toilet water supply means 30, and a linked operation described later provided for controlling the cooperative operation of the entire urination information measuring device 1. A state display means 82a and a state receiving means 82b that constitute the control means 80 are provided.

Further, the urine volume measuring unit 5 is composed of a urine volume measuring unit 6, and the urine volume measuring unit 6 further includes a urine volume measuring unit 50 having a mechanism necessary for measuring a change in the water level of the pooled water 23. The urine volume measurement control unit 60 controls the operation of the urine volume measurement unit 50, processes the obtained measurement information, and calculates the measurement information such as the urine volume.

The urine volume measuring unit 50 includes a pooled water level measuring means 51 that measures a change in the water level of the pooled water 23 in order to measure the amount of urine discharged due to excretion of the subject, and a water level of the pooled water 23 due to a pressure fluctuation in the sewage pipe. Sewage pressure fluctuation measuring means 52 for measuring the amount of influence, and calibration-related measuring means 53 for measuring the relationship between the water level and the amount of water in the pool 20 in the bowl 20 (hereinafter, this relationship is referred to as "calibration-related"). And a pipe edge cutting means 55 for blocking the flow of air by sealing the connecting pipe line between the urine volume measuring unit 50 and the sewage pipe with water.

The pooled water level measuring means 51 is connected to the pooled water 23 by a measuring pipeline 57, which will be described later, and both are communicated with each other via this pipeline. The measuring pipe 57 is provided with a measuring pipe opening / closing means 57a that closes the pipe when it is not needed, in order to prevent damage to the pooled water level measuring means 51.

Further, the sewer pressure fluctuation amount measuring means 52 is also connected to the sewage pipe by the sewage pipe connecting pipe line 522, which will be described later, which communicates with the inside of the drainage socket 15, but this cuts off the air flow from the sewage pipe. It is connected via a pipe edge cutting means 55 that prevents backflow of odor.

In the present embodiment, the pooled water level measuring means 51 includes a head pressure measuring means 51a that measures the water level of the pooled water 23 as a head pressure that is the pressure of the water column generated at that time, and an actual water level measuring of the pooled water 23. At the same time, a measurement output calibration means 51b that creates a reference head pressure in advance and calibrates the output of the head pressure measuring means 51a is also built-in. The measurement output calibration means 51b also functions as a vibration isolating means for removing the influence of the ripples of the pooled water 23 on the water level measurement of the pooled water level measuring means 51.

Further, the urine volume measurement control unit 60 is provided with urine volume information such as the amount of excrement such as urine excreted by the subject in the pool water 23 and the urine volume information based on the water level information measured by the pool water level measuring means 51. The urine volume information calculation means 61 to be obtained, the measurement information storage means 62 for storing the measurement information such as the measurement information and the measurement information necessary for the measurement of the calibration relation and the like performed by the calibration relation measurement means 53, and the toilet water supply means 30 described above. A measurement start water level formation control means 63 constituting a measurement start water level forming unit is provided, which forms the water level of the reservoir 23 at the measurement start water level by controlling via the water supply control means 41.

The measurement pipeline opening / closing means 57a is provided with a calibration curve measuring means 53 together with the pooled water level measuring means 51, and the calibration curve measuring means 53 reduces the pooled water 23 by a predetermined amount a plurality of times while collecting the pooled water. The water level measuring means 51 measures the water level, obtains a calibration curve which is a correspondence relationship between the water level and the water amount from a plurality of pairs of the obtained water reduction amount and the water level, and obtains a calibration curve which is included in the measurement information storage means 62. The calibration curve storage means 621 constituting the generation unit stores the calibration curve as a provisional calibration curve.

The calibration curve calibration means 622 constitutes a calibration curve generation unit, and calibrates the provisional calibration curve stored in the calibration curve storage means 621 to obtain a true calibration curve. As a concept of the calibration curve storage means 621, in the method as shown in FIG. 3 described later, a rough calibration relationship with low quantitativeness is used and a rough calibration relationship is performed without setting so many calibration points. Obtain a provisional calibration curve, and modify the provisional calibration curve with a calibration curve calibration means to obtain a true calibration curve.

Further, as shown in FIG. 4, which will be described later, the main calibration curve, which does not have the calibration curve measuring means 53 and is preset and stored in the calibration curve storage means 621, is calibrated by a simple correction work at the time of construction. It may be a product-specific calibration curve. When the mechanical dimensional accuracy of the bowl 20 is high, it is not necessary to make the calibration-related measuring means 53 indispensable in this way. For example, the bowl 20 is made of a resin material such as acrylic resin instead of pottery. If so, such a method can configure the biological information measuring device 1 at a lower cost.

The measurement information storage means 62 is provided with a calibration curve calibration means 622 for correcting the calibration relationship between the accumulated water level and the accumulated water amount stored in the calibration curve storage means 621. As the method of inputting the correction value, considering that this operation is performed only at the time of construction or periodical verification, the maintenance cover provided on the operation / display unit 70 is opened and the switch as the calibration value input means 74. One switch may be used for a plurality of purposes as another switch as the calibration value input means 74 by operating after exposing the switch or pressing a predetermined switch for a long time.

Further, a state display means 83a and a state receiving means 83b, which constitute a linked operation control means 80 described later for controlling the linked operation of each function of the biological information measuring device 1, are provided.

The urine volume information calculation means 61 uses the calibration relationship between the water level stored in the calibration line storage means 621 and the water volume from the water level of the reservoir 23 measured by the reservoir water level measuring means 51. The state of the sewage pressure at the start of the pooled water level measurement with the water level measured by the pooled water level measuring means 51 using the measurement results of the pooled water amount calculating means 61a and the sewage pressure fluctuation amount measuring means 52. The sewage pressure fluctuation correction means 61b for correcting the value in is provided.

The urine volume information calculating means 61 has the above configuration, and is based on the corrected pooled water level value obtained by correcting the pooled water level value measured by the pooled water level measuring means 51 by the sewage pressure fluctuation correcting means 61b. The water amount calculating means 61a calculates the amount of accumulated water at that time to obtain urine amount information such as the urination amount.

In the biometric information measuring device 1 of the present embodiment, as described above, since the toilet bowl unit 3 and the urination information measuring unit 5 have independent configurations, the operating units that give operation instructions are also separate operating units. The remote controllers 71 and 72 are provided, and these remote controllers 71 and 72 are independent remote controllers that do not exchange operation information with each other. On the other hand, the bowl 20 of the normal toilet bowl is also used as a urine collection container at the time of measuring urination information. In some cases, such as between the urination movements, one movement affects the other movement, resulting in measurement errors or damage to the instrument.

Therefore, it is defined how to operate each of the toilet bowl unit 3 and the urination information measurement unit 5 according to the operation status at that time in response to an operation instruction by an arbitrary remote control operation performed by the user. A means for performing linked operation control is required, and for this reason, the linked operation control means 80 is also provided in the present embodiment as described above. Although a specific control circuit is required to perform this linked operation control, the urination information measuring unit 5 and the toilet bowl unit 3 are connected via the relay board 81.

Instead of providing a circuit board separately from both control circuit boards as in the relay board 81, the toilet control unit 40, which is the control means of the toilet unit 3 to be linked operation control, or the same target. It is also possible to integrally incorporate this control circuit into any control circuit board of the measurement control unit 40, which is the control means of the urination information measurement unit 5. Further, as yet another embodiment, it is possible to configure these plurality of control circuits as one circuit board.

The linked operation control means 80 in the present embodiment includes a relay board 81 provided as a control circuit board between the toilet bowl unit 3 and the urination information measurement unit 5, and a state display means 83a provided in the urine volume measurement control unit 60. The state receiving means 83b, and the state displaying means 82a and the state receiving means 82b provided in the toilet control unit 40 are provided. Hereinafter, these control operations will be described.

The status display means 82a and 83a transmit the operation information of the toilet bowl unit 3 or the urination information measurement unit 5 to the relay board 81, respectively. The relay board 81 generates and stores predetermined linked operation information according to the operation state at that time based on the operation information of the toilet bowl unit 3 or the urination information measurement unit 5 that has been sent. That is, the relay board 81 is configured to constantly aggregate and store the operating states of both.

Then, when the urine volume measurement control unit 60 or the toilet bowl control unit 40 starts each operation, the state receiving means 82b and 83b provided in each of the urine volume measurement control unit 60 or the toilet bowl control unit 40 are generated and stored by the relay board 81. With reference to the linked operation information, the operation of the toilet bowl unit 3 or the urine volume measuring unit 6 is controlled as predetermined. When the interference operation is predicted for the entire biological information measuring device 1, the above-mentioned linked operation information is matched and adjusted by switching to the interference prevention operation or transmitting the drive signal by delaying it. It is predetermined so that mutual interference does not occur.

FIG. 3 is a schematic side sectional view showing the toilet bowl unit 3 and the biological information measuring unit (urination information measuring unit) 5. Specifically, FIG. 3 shows the relationship between the water pipes of the toilet bowl unit 3 and the urination information measuring unit 5 in the configuration shown in FIG. In FIG. 3, the details of the sanitary cleaning device 7 are omitted.

As shown in FIG. 3, the toilet bowl 4 is connected to the sewage pipe port 16 via the drainage socket 15. The pooled water 23 formed by the trap 14 has a role of sealing water that cuts off communication with the sewage pipe, so that odors and sanitary pests generated in the sewage pipe do not enter the toilet. Consideration is given to the aspect.

Y can be obtained.

At the time of the measurement start water level forming operation for forming the measurement start water level, the water supply pump 324 is operated to supply water from the refill tank 322 at a predetermined water supply rate for a predetermined time to control the measurement start water level forming operation. The water supply control regarding the water supply operation time and / or the water supply rate is performed by the measurement start water level formation control means 63 described above.

Water is supplied to the refill tank 322 by the on-off valve 323, but a predetermined amount is detected by the float switch 325, and in the unlikely event of a malfunction, the overflow pipe 326 discharges the water toward the sewage pipe port 16. Care is taken to prevent water leakage to the outside of the device.

The accumulated water level during standby is the measurement start water level Y, and 50 mm or more and 100 mm or less specified in the Building Standards Law Construction Ordinance so that there is no risk of the accumulated water running out (breaking) due to pressure fluctuations generated in the sewage pipe. Must be set to. By ensuring a predetermined amount of water sealing depth, it is not necessary to pay attention to hygienic problems such as odor in the sewage pipe leaking into the toilet and sanitary pests invading the toilet.

The urine volume measuring unit 50 includes a measuring pipeline 57 that communicates with the pooled water level measuring means 50 from a water level measuring port provided on the inner surface of the substantially bottom portion of the bowl 20 for measuring the water level of the pooled water 23, and a sewage pipe.

The pressure sensor 512 is provided in the water level measuring pipe 511 in order to measure the water level of the pooled water 23 as the head pressure of the U-shaped pipeline system.

Further, since the output of the head pressure measurement pressure sensor 512 changes depending on the temperature change of the installed environment and the time-dependent change of the sensor itself, in the present embodiment, the measurement output calibration means 51b for calibrating the output of the pressure sensor 512 It has.

That is, with the on-off valve 571 of the measuring pipe 57 closed, the water stored in the water supply storage tank 322 is guided to the measuring pipe 511 via the on-off valve 582 and the on-off valve 513, and trapped from the water seal end 515. By overflowing into the tank 551, a water column having a constant height is created in the water level measuring pipe 511. Then, by measuring the output of the head pressure measurement pressure sensor 512 of the constant height water column, the output calibration is performed so that the relationship between the output of the head pressure measurement pressure sensor 512 and the water level corresponds to the water level based on the atmospheric pressure. ..

The trap tank 551 is a drainage socket 15 at a sewage pipe connecting pipe 522 extending from a position where a sealing water is formed inside in order to discharge the overflow water from the measuring pipe 511 at the time of output calibration to the sewage pipe. It is connected to the sewage pipe and functions as a cutting means for cutting the edge by sealing the connection line with the sewage pipe.

Further, the biological information measuring device 1 of the present embodiment also includes the above-mentioned calibration relationship measuring means 53 for obtaining the calibration relationship in the present invention, which is the correspondence relationship between the water level of the pool water 23 and the amount of pooled water. In the conventional urination information measuring device, when the toilet bowl 4 is made of pottery having a relatively large variation in physical dimensions, the relationship between the pooled water level and the pooled water level is measured and returned at many points. I was getting a straight line. In consideration of the shape variation peculiar to each individual toilet bowl 4 and the construction variation including the floor inclination of the construction site, the true calibration relationship was measured and obtained at the installation site.

Therefore, as the calibration pump 531, a fixed-quantity suction type pump capable of sucking an arbitrary amount is used, and the accumulated water 23 is sucked by the calibration pump 531 to suck the measurement pipe 57, the water stop valve 541, the on-off valve 571, and open / close. It is configured so that it can be discharged toward the sewage pipe via a valve 532, a calibration pump 531, a trap tank 551, and a sewage pipe connecting pipe 522.

Then, at the installation site, the water level of the reservoir 23 is set to a water level equal to or higher than the maximum water level in the measurement range, and the on-off valve 513 and the on-off valve 582 are closed. By measuring the water level by measuring the water head pressure generated by the water level at each suction with the water head pressure measurement sensor 511, the calibration relationship between the water level and the amount of water accumulated can be obtained. It has become.

In the present embodiment, since the calibration relationship can be modified by the method described later, the quantification of the calibration pump 531 does not require an excessive amount, and the measurement points of the accumulated water level and the accumulated water amount are repeatedly carried out. Can also be reduced. Cost reduction can be expected, and the time required for construction and setting can also be shortened.

If the individual difference between the accumulated water level and the accumulated water amount is small, the entire calibration curve measuring means 53 is omitted, and the calibration curve created in advance is stored in the calibration curve storage means 621, and this calibration curve is stored in the calibration curve. It may be calibrated by the calibration means 622 to be a true calibration curve for each device. Such a configuration can be applied to a pottery toilet bowl in which the blending amount of each component of the material and the firing temperature are adjusted, or a toilet bowl in which at least the bowl portion is made of resin.

Further, the sewage pressure measuring sensor 521 as the sewage pressure fluctuation amount measuring means 52 in the present embodiment is attached to the trap tank 551 and is connected to the trap tank 551 and the socket 15 via a sewage pipe connecting pipe 522. The pressure fluctuation state generated inside is measured as a pressure value. The water pressure fluctuation correction means 61b calculates the influence amount of the sewage pressure fluctuation on the reservoir water level based on the measurement value by the sewage pressure influence amount measuring means 52, and the water level measurement value measured by the reservoir water level measuring means 51 is always. Correction processing is performed to convert the value to the value when there is no sewage pressure fluctuation.

The urination information measuring unit 5 prompts the execution of the updating work of the biological information measuring device 1 based on the calibration curve by the calibration curve generating unit that is periodically operated. That is, a guide is issued to the medical staff and the like to carry out the update work of the biological information measuring device 1. Further, the urination information measuring unit 5 prompts the execution of the updating work of the biological information measuring device 1 based on the calibration curve by the calibration curve generation unit operated by the predetermined operation.

In this case, as will be described later, the urination information measuring unit 5 prompts the execution of the updating work when a difference of a predetermined value or more is detected as compared with the previous calibration curve. Further, the urination information measuring unit 5 prompts the execution of the updating work when the correlation coefficient change of a predetermined value or more is detected as compared with the previous calibration curve. Further, when the urination information measuring unit 5 prompts the execution of the updating work of the biological information measuring device 1, the urination information measuring unit 5 notifies the notification unit 72a (see FIG. 1) such as a monitor or a lamp provided in the operation / display unit 70. ..

According to such a configuration, it is possible to detect the time-dependent fluctuation of the drainage pipe and the time-dependent fluctuation of the biological information measuring device based on the calibration curve generated by the calibration curve generation unit. This makes it possible to maintain high accuracy for clinical trials for a long period of time. That is, it is possible to secure a level of accuracy that can be used for various clinical trials so as not to interfere with daily medical practice.

In this case, by detecting a difference of a predetermined value or more as compared with the previous calibration curve, it becomes possible to detect the time-dependent fluctuation of the drainage pipe and the time-dependent fluctuation of the biological information measuring device based on the calibration curve. Further, by detecting a change in the correlation coefficient of a predetermined value or more as compared with the previous calibration curve, it becomes possible to detect the time-dependent fluctuation of the drainage pipe and the time-dependent fluctuation of the biological information measuring device based on the calibration curve.

Further, by notifying the notification unit 72a, for example, a person in charge of a medical institution can be made aware of the implementation of the update work. As a result, the update work can be performed at an appropriate timing, and the decrease in accuracy due to not performing the update work can be suppressed.

FIG. 4 is an explanatory diagram of an execution determination of the update work of the biological information measuring device 1. FIG. 4 conceptually shows a method of modifying the calibration relationship between the accumulated water level and the accumulated water amount. The measurement information storage means 62 is provided with a calibration curve calibration means 622 for correcting the calibration relationship between the accumulated water level and the accumulated water amount stored in the calibration curve storage means 621.

Here, as a method of notifying the notification unit 72a (see FIG. 1) that it is necessary to update the biological information measuring device 1, four types of methods as shown in FIGS. 4 (a) to 4 (d) are used. I will explain in detail.

FIG. 4A shows an example when the slope of the calibration curve changes. In this case, as shown in FIG. 4A, it is assumed that the output value has changed due to the deterioration of the head pressure measurement sensor 512 over time. It is easy to find when trying to measure a large urine volume or urine flow rate, but it is assumed that it will not be detected because only the low part is often measured especially in urological medical institutions.

FIG. 4B shows an example when a predetermined portion of the calibration curve changes. In this case, as shown in FIG. 4B, it is assumed that a local foreign substance adheres to the bowl 20. Since there are no abnormalities in the measured values other than this part, it is assumed that they cannot be detected.

FIG. 4C shows an example when the intercept of the calibration curve changes. In this case, as shown in FIG. 4C, it is assumed that the output value has changed due to the deterioration of the head pressure measurement sensor 512 over time. In this case, as in the case illustrated in FIG. 4A, if the measured urine volume and urine flow rate are limited, the fear of abnormality detection may be delayed.

FIG. 4D shows an example when the calibration curve does not change. In this case, as shown in FIG. 4D, a failure of the head pressure measurement sensor 512 is assumed, and maintenance should be performed immediately regardless of the discovery by a medical personnel.

For example, the urination information measuring unit 5 compares the estimated value and the estimated amount rate in the predetermined urine volume with those at the time of the previous update work of the biological information measuring device 1. Then, the urination information measuring unit 5 notifies the notification unit 72a (see FIG. 1) of the comparison result. By notifying in this way, it becomes possible to promote subsequent work decisions according to the characteristics of the medical institution in which the biological information measuring device 1 is installed.

If the change in the calibration curve is confirmed regularly (the recommended time is a time that is unlikely to be measured), it is estimated that the effect of clinical work is small. And / or, the change of the calibration curve may be confirmed by a predetermined operation. In addition, it is also recommended to perform a confirmation operation when the medical personnel feel an abnormality in their sensibilities. By measuring changes in the calibration curve and guiding the implementation of renewal work when a change in the correlation coefficient that exceeds a predetermined value is detected compared to the previous calibration curve, the need for renewal and calibration can be communicated to medical institutions. It will be possible to urge the person in charge.

The sensor output E of the head pressure measurement sensor 512 is represented by using an approximate curve with respect to the water level X. In this case, various methods are used to represent the approximation curve, such as Lagrange approximation, as well as polynomial approximation. As a matter of course, as shown in the following equations (1) to (3), there will be a difference between the approximate curve when the previous calibration was performed and the approximate curve when the current calibration was performed as time passed. ..
At the time of the previous calibration E1 = f1 (X) ... (1)
At the time of this calibration E2 = f2 (X) ... (2)
E1 ≠ E2 ... (3)

Further, for example, if the accuracy for a predetermined amount as shown in the table below is notified by a percentage display in addition to the above-mentioned correlation coefficient while guiding the execution of the update work, the biometric information measuring device 1 is introduced. It is easy for medical institutions to decide what to do. High accuracy is required for low urine volume High accuracy is achieved at high urine volume between medical institutions whose main disease is urinary function and who want to evaluate the condition of the lower urinary tract and medical institutions that perform metabolic control before and after surgery based on urine volume. This is what is required, and it is possible to encourage medical staff to judge the necessity of coping.

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.
