Description

  The present invention relates to a combination with a urine flow measurement device used in a medical institution, and grasps a urination state suitable for easily measuring a urination state at home even for a subject who has no special knowledge. It is invention regarding the urination amount measuring system for doing.

  A urination record that records the time and volume of urination over a long period of time for patients with dysuria is useful for urologists and gynecologists to understand the patient's dysuria status. Information. Therefore, the patient measures the amount of urination with a beaker or the like and records it in a predetermined recording form called a urination diary together with the urination time.

  In this case, urination when healthy is about 5 to 6 times / day, but in the case of patients with dysuria, the frequency of urination often increases. For example, urination is continuously recorded for about one week. In addition, the measurement itself is very troublesome, and in addition, it is necessary to clean up the equipment used such as contamination of the measurement site due to urine spills and the like, and washing of the beaker used.

  Here, among the patients with urination disorders as described above, there are many patients who are treated by regular hospital visits because the symptoms are relatively mild and do not require hospitalization. In such a case, measurement at the patient's home is necessary for the continuation of the measurement. However, in this case, not only measurement / recording by the patient itself but also the cleaning up to the end of the used device is a burden on the patient alone. For this reason, it may be possible to seek the cooperation of family members and caregivers, but there are also problems such as the family members and caregivers not having enough time to do the cooperation.

  In addition, as described above, in order to continuously record the urination time and the urination amount over a long period of time at home or the like, it is natural that a measuring device is necessary.

As a method for hygienically measuring urine volume, there is one that automatically measures urine volume, urination time, etc., simply by excretion in a Western-style toilet (see, for example, Patent Document 1).
This device has the advantage of being able to measure urination information just by excreting it in a normal toilet, and eliminating the need for work to process the excrement. This is the most recommended method to know. However, since it is necessary to replace the toilet installed in the home with a toilet with a urine information measurement function, the cost burden on the patient is large, and the urine volume measurement function from the toilet becomes unnecessary after the disease is improved. In view of this, there was an economic problem with its introduction.

In addition, there is a type in which a urine flow is detected by a radio wave sensor using a Doppler effect of a radio wave having a wavelength in the microwave band, and the amount of urination is estimated from the urine flow detection time to control the amount of washing water (for example, Patent Literature 2).
However, the technique used in this case estimates the amount of urination based on the assumption that the relationship between urination time and urine volume is constant, and the relationship between actual urination time and urine volume varies depending on the individual. Therefore, there is a limit in performance, and it is impossible to measure urine volume information with high accuracy as used for medical purposes for individuals.
Japanese Patent No. 3876919 JP 2004-100377 A

  The present invention has been made to solve the above problems, and the object of the present invention is to allow a patient with dysuria who has no special knowledge to continuously and conveniently measure urine output at home. In addition, the present invention provides a urine volume measurement system that has a small economic burden on patients.

In order to achieve the above object, according to the first aspect of the present invention, urination for continuously measuring the amount of urination, which is the amount of urine excreted by the subject, and recording it together with the time of urination to create a record of urination of the subject. In the volume record creation device, a urine flow rate acquisition unit that acquires in advance a urine flow rate that is the amount of urination per unit time of the subject and stores it in association with the subject, and a urination time measurement unit that measures the urination time of the subject When,
Urine volume calculating means for determining the urine volume of the subject based on the urine flow rate and the urination time;
A base member that functions as a housing in which the urine flow rate acquisition means, the urination time measurement means, and the urine volume calculation means are disposed;
By determining the amount of urination by measuring the urination time in a state in which the base member is detachably fixed to an existing Western-style toilet,
It was made possible for patients with dysuria who have no special knowledge to measure urine output simply by urinating at home.

According to a second aspect of the present invention, in the first aspect of the invention, the urine flow rate acquisition means is a urinary flow obtained from a correlation between a urination time measured at a medical institution and a urine output. By obtaining a rate as the urine flow rate,
Since the urinary flow rate, which is correlation information related to urination, is updated by information confirmed by medical personnel at a medical institution, the amount of urine can be measured with high reliability.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the urination time measuring means is at least one of urine movement or displacement of the stored water surface in the Western-style toilet. By providing a radio wave sensor that measures the urination time by detecting the frequency transition of the radio wave by
It was possible to measure the urine flow time of a subject in a general household toilet, and as a result, it was possible to measure urine volume in a household toilet. Since the radio wave sensor provided approximately in front of or on the side of the Western-style toilet can be retrofitted, it is possible to suppress the patient's economic burden related to attaching the measuring means.

According to a fourth aspect of the present invention, in the first or second aspect of the invention, the urination time measuring means includes a microphone that measures the urination time by detecting sound pressure information due to urine movement. Because it is characterized by having,
Without requiring an expensive radio wave sensor or frequency analysis means, an inexpensive microphone can be used to realize the urine output recording creation system of the present invention.

According to the invention described in claim 5, in the invention described in any one of claims 1 to 4, further comprising a foot switch for starting a urine volume measuring operation by a foot operation. ,
The patient of the subject can obtain urination information hygienically.

According to the invention described in claim 6, in the invention described in any one of claims 1 to 5, further, sensory information at the time of urination of the subject or bedtime as urinary supplementary information incidental to the subject's urination action Urination incidental information input means for inputting at least one of the information,
Since it is output as a list of predetermined periods describing the urine supplementary information together with the urine volume and urination time,
The subject not only has the trouble of creating the urination volume record while remembering the urination state, but also can create an accurate urine volume record without leakage. In addition, medical personnel can now make an error-free diagnosis for incomplete urination records without having to guess the content and extent of the disease.

According to the present invention, attention is paid to the fact that the correlation between urination time and urination volume is high when a patient is specified. By using the correlation between urine flow time measured at other places such as medical institutions and urine output, and by making it possible to measure urine flow time in the toilet at home, the urine output is estimated from the measured urine flow time, In particular, there is an effect that a patient with dysuria who does not have specialized knowledge can obtain a record of the amount of urination in a hygienic and unconstrained manner by simply urinating in the toilet at home.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing a first embodiment of a urine output record creating apparatus according to the present invention. The urine output record creation device 40 includes a base member 44 serving as a housing, and is attached in front of a Western-style toilet 31 used at home.
Arranged at the upper part of the base member 44 is the radio wave sensor 1, and arranged at the lower part is an activation switch 42 for activating the urine volume measurement operation.

  The radio wave sensor 1 includes a radio wave transmitter that transmits radio waves in the microwave wavelength band from the outer wall of the toilet 31 toward the inside of the bowl, and a radio wave receiver that receives reflected waves reflected from the inside of the bowl 65. . When the subject starts to urinate while transmitting the radio wave from the radio wave transmission unit, the radio wave is reflected by urine and a part of the reflected wave returns to the radio wave reception unit. The frequency of the radio wave transitions due to the movement of. Therefore, by monitoring the presence / absence of this frequency transition, the presence / absence of urine particles, that is, the presence / absence of urine flow accompanying urination can be discriminated, so that it functions as the urinary flow detection means in the present invention.

  The start switch 42 is a stepping type. Hygiene is also taken into consideration by allowing the user to operate naturally when approaching the toilet and not touching the hand. In front of the control unit 41, a storage medium insertion unit 43 for inputting correlation information for estimating urination information, which will be described later, or for taking out a urination diary as a urination record as a measurement result of a predetermined period as electronic data. Is provided. The user starts the measurement by stepping on the start switch 42 during urination, and when the urination is finished, the user steps on the start switch 42 again to end the measurement.

  Between the Western-style toilet 31 and the base member 44, it is fixed with respect to the earthenware by a gel-like buffer having adhesiveness (not shown). Here, the base member 44 has a bendable structure made of a flexible material, so that it can cope with the variety of toilet bowl shapes caused by the variety of design of Western-style toilets. It is designed to allow for installation.

  Specifically, it is recommended that the base member 44 has a flexible core material such as a free ruler. Further, by selecting a gel-like buffer that has adhesiveness and tackiness but not adhesiveness, it is considered that it can be easily removed after the patient's disease treatment is completed. Therefore, for example, a method in which the urine volume record creation device 40 is owned by a medical institution and is lent to a patient who needs to obtain a urine record can be used as a specific operation example.

  Although the embodiment is described as having a cabinet 35 having a storage function, a sanitary washing device 36, a toilet seat 37, and a toilet lid 38 on the back of the Western-style toilet 31, the embodiment is particularly caught by the appearance of the embodiment. is not. Moreover, although the urine output record creation device 40 of the present embodiment is described as an integrated unit of all the mechanisms, for example, the control unit 41 is configured as a separate unit and separated from the Western-style toilet 31. However, the aim of the present invention does not change.

  FIG. 2 is a cross-sectional view showing a urine output record creating device 40 which is a first embodiment of the urine volume record creating device according to the present invention. In this figure, focusing on the measurement function, the portions not directly related to the measurement function are omitted. In general, a Western-style toilet 31 made of earthenware is sealed with a bowl surface 32 that receives urine 20 excreted by the user 10, water 33 stored in the bowl surface 32, and sewage (not shown). A trap 34 is formed.

  The urine 20 exiting the urethral opening of the user 10 seated on a toilet seat (not shown) falls along the dry surface of the bowl surface 32 not in contact with the stored water 33 or directly onto the stored water 33. Part of the urine mixed water 33 flows into the sewage through the trap 34. When toilet cleaning is performed, the urine mixed water 33 is pushed out by the wash water supplied to the bowl surface 32 and discharged into the sewage.

  The urine volume detection means 1 is installed on the outer wall portion of the western-style toilet 31 in front of the bowl surface 32 so as to face the bowl surface 32. Since the radio wave 5 transmitted from the urine volume detecting means 1 has a property of passing through the pottery, the upper part of the bowl surface 32 is transmitted from the front of the Western-style toilet 31 to the rear. When the user 10 urinates, the transmitted radio wave 5 collides with the urine 20, and a part thereof is reflected and received by the urine volume detection means 1.

  The urine excretion time can be determined based on the time during which a differential frequency component is generated between the reflected radio wave that has been frequency-shifted by the Doppler effect due to the falling movement of the urine that is the reflection target and the transmission radio wave. . Further, it may be determined based on the time during which the intensity of the reflected radio wave due to urine is a certain level or more.

  When the user 10 is a male, urine is excreted from the urethral orifice at the tip of the penis, so the flow of the urine 20 is excreted forward as shown in FIG. When the user is a woman, the excretion direction of the urine is downward and falls into the accumulated water 33.

   FIG. 3 is a graph showing a state in which actual measurement values of cases in which the relationship between the urine flow time during urination and the amount of urination is measured a plurality of times for a plurality of subjects (male) are accumulated. The urine flow time T is a cumulative time during which urine is discharged. Naturally, each subject has a relationship that the urination amount R is larger as the urine flow time is longer, but the degree of correlation is not so high.

  This is because the urinary flow rate, which is the amount of urination per unit time, varies from subject to subject due to individual differences in the diameter of the urethra or individual differences in the amount of muscle added to the bladder for excretion. . From this, it can be seen that the urine flow time T provides an indication that the urination volume R is large or small, but the specific urination volume R cannot be estimated by the urine flow time T alone.

The correlation measured by the applicant with 30 healthy Japanese men and women in their 20s and 50s was as follows.
That is, in men,

In women

Met.

   FIG. 4 is a graph showing actual measurement values of examples in which the relationship between the urine flow time during urination and the amount of urination is measured a plurality of times for each of a plurality of subjects. In this case, it can be seen that the urine flow time and the amount of urination are clearly highly correlated.

  This is presumably because the variation in the urethra diameter, which causes the decrease in the correlation, the amount of muscle added to the bladder for excretion, etc., has decreased in individual units as described above. From this, it can be seen that by measuring the urine flow time T, the urine output R can be estimated with high accuracy.

  That is, when the correlation coefficient k is used for the urine flow time T and the urine output R, it has been confirmed that the following relational expression is established with a high degree of correlation for each subject.

  Here, the correlation coefficient k in [Equation 3] has a different value for each subject. In particular, in the case of a subject who has some symptom in the excretion function, the value of the correlation coefficient k can be changed by the change in the symptom even in the same subject. Also changes.

  For example, in the case of a patient with poor urine output due to benign prostatic hyperplasia, the correlation coefficient k is estimated to be 5 [mL / s] or less, but the value is improved by treatment, and the above-mentioned healthy 20 This is close to about 15 [mL / s] shown in [Formula 1] obtained by clinical monitor analysis of Japanese men in their 50s to 50s.

  Therefore, in the urine volume record creating apparatus embodying the present invention, the correlation coefficient k is appropriately updated using the correlation coefficient obtained from the relationship between the urine flow time T and the urination volume R measured at the medical institution. Thus, it is possible to continuously measure the urine flow time T and estimate the urination amount R with high accuracy.

FIG. 5 is a system block diagram showing the first embodiment of the urine volume record creating system using the first embodiment of the urine volume record creating apparatus according to the present invention.
The urine volume record creating system of the present embodiment includes the urine volume record creating device 40 installed in the subject's residence, the urine information measuring device 60 installed in the medical facility where the subject goes to the hospital, and the urine volume record creating device. 40 and an electronic recording medium 70 serving as data transfer means for transferring various data between the urination information measuring device 60 offline.

  The medical staff uses the urination information measuring device 60 installed in the medical facility to measure the relationship between the urine flow time T and the urine output R of the patient who is the subject. The data of the urine flow time T and the amount of urination R are recorded as correlation data for calculating the correlation coefficient k in an electronic recording medium 70 such as a semiconductor memory card as data transfer means, and delivered to the patient. It has become.

  Then, when the patient attaches the electronic recording medium 70 to the urine volume record creating device 40 installed at home, the urine volume record creating device 40 determines from the data of the urine flow time T and the urine volume R. The latest correlation coefficient k is stored as data for calculation. As a result, the urination volume record creation device 40 can calculate the urination volume using the latest correlation coefficient k, and thus can accurately measure the urination volume even at home.

  First, a urination information measuring device 60 installed in a medical institution will be described with reference to FIG. This urination information measuring device 60 has the same configuration as that disclosed in Japanese Patent No. 3876919 by the present applicant. It is a device that easily measures urine volume, urinary flow rate, etc. in the toilet to obtain various urination information, and is also recommended as a means for obtaining the correlation coefficient k between the urine flow time T and the urine volume R, The configuration is not limited to this method, and any correlation coefficient k may be obtained.

  The urination information measuring device 60 is provided in the Western-style toilet 61. A bowl 65 from which the subject excretes is formed inside the Western-style toilet 61, and the inside of the bowl 65 is communicated from the trap part 63 to the sewage pipe through the drain socket 62. In the bowl 65, a trap water 63 is formed by the trap portion 63 to function as a sealing water for the sewage pipe, and sanitation is taken into consideration so that odors and sanitary pests generated in the sewage pipe do not enter the toilet. Has been. Further, a water level forming means 66 connected to city water and supplying water into the bowl 65 is provided.

  Inside the bowl 65, a rim water discharge nozzle that discharges water into the bowl 65 to form the inner peripheral surface and forms the accumulated water 64 is provided at the upper part, and a jet water discharge nozzle that discharges waste to the sewage pipe by the water discharge is provided at the lower part. , Respectively.

  A water supply path from the water level forming means 66 to the rim water discharge nozzle is a rim water discharge flow path 66a, and a water supply path to the jet water discharge nozzle is a jet water discharge path 66b. The jet water discharge channel 66 b has a branching portion 66 c and is branched and connected to the stored water level measuring means 67. The stored water level measuring means 67 is for transmitting the water level head of the stored water 64, and a vibration removing means 67a for mechanically and electrically removing vibrations generated in the pressure conduit, which will be described later. A calibration means 67b for absolute calibration of the water level measurement pressure sensor is incorporated.

  A water level difference measuring means 68 for measuring the influence of fluctuations in the sewage pressure is connected to the drain socket 62 which is a connection portion with the sewage pipe. A water level forming unit 66, a stored water level measuring unit 67, an operation / display unit 80, and a water level difference measuring unit 68 that measures the influence of fluctuations in the sewage pressure are connected to a common control unit 69, and each controls the water supply operation. Various controls such as measurement of urination information, operation reception processing of the subject and output of measurement results are performed.

  Here, the water level difference measuring means 68 for measuring the influence of the fluctuation of the sewage pressure gives the pressure fluctuation of the sewage pipe to which the present apparatus is connected to the level of the stored water of the toilet used by the present apparatus for the urine volume measurement. In this embodiment, a pressure sensor is installed in a pipe line communicating with the drain socket 62, and the pressure fluctuation of the trap part 63 of the toilet bowl is measured as the influence amount factor. . As a method of installing the pressure sensor, as long as the pressure fluctuation of the sewage pipe can be measured, the installation form is not limited. In addition to this, it is also possible to install the pressure sensor in the toilet trap or measure the pressure fluctuation of the sewage pipe.

  This pressure sensor is assumed to be a semiconductor pressure sensor, but the built-in semiconductor diaphragm may generate a drift phenomenon in which the output changes depending on the energization and the environmental temperature. The amount of difference from the pressure value being measured is measured using the pressure value immediately before the start of measurement as a reference value. It is the water level calculation means 69a that performs correction calculation of the stored water level measured by the stored water level measurement means 67 using the influence amount of the sewage pressure fluctuation on the stored water level.

  In addition to this, as a method of measuring the influence amount, it is also possible to employ a method in which various water level measuring means usually used for measuring the water level change of the stored water caused by the influence of the pressure fluctuation of the sewage pipe are provided. Is possible. In this case, since the amount of change in the water level due to the pressure fluctuation of the sewage pipe, which is the background of the present invention, can be obtained directly, correction of the stored water level measurement value obtained by actual urine volume measurement is simplified.

  When measuring urination information, the water level of the stored water is lowered to the measurement start water level Y lower than the overflow water level H, and the difference in the amount of stored water between the overflow water level H and the measurement start water level Y is called the measurement range of urination information. It will be. If the pressure fluctuation in the sewage discharge pipe is large, the accumulated water flows over the overflow water level H of the trap part, and the correspondence between the water level and the amount of accumulated water is destroyed. That is, in the case of negative pressure, the accumulated water is sucked in the direction of the sewage pipe as it is, and overflow occurs. In the case of positive pressure, when unloading occurs, the stored water shakes back, and an overflow phenomenon occurs in which the stored water flows out toward the sewage pipe.

  Therefore, in the present technology, the urination information calculation unit 69b calculates the urination information using data until the fear of the overflow of the stored water is detected based on the measurement result of the sewage pressure fluctuation. The urination information calculation is performed based on the stored water level measured by the stored water level measuring unit 67 and the pressure in the sewage pipe measured by the water level difference measuring unit 68 that measures the influence of fluctuations in the sewage pressure. Means 69b.

  In this embodiment, a pressure sensor capable of taking an output proportional to the change in the water level is used as the water level detecting means of the stored water level measuring means 67. The measurement principle is that the water level measurement value obtained by the pressure sensor is converted into the amount of stored water from a calibration curve obtained from the relationship between the water level stored in advance and the amount of stored water. The urination information such as the urine flow rate is obtained from the differential coefficient of the accumulated water volume fluctuation curve over time, and the urination volume at an arbitrary time from the start of measurement is accurately calculated by performing this continuously during urination. be able to. In this case, since the water level fluctuation can be directly measured, the configuration of the apparatus is simplified.

  In order to obtain the amount of accumulated water at that time from the measured water level of the bowl part, it is necessary to obtain in advance a calibration curve which is the relationship between the amount of accumulated water at any bowl part water level. Because it is manufactured and has large individual differences in terms of shape, in this embodiment, a function for obtaining a calibration curve is provided, so that the difference between individuals in the toilet bowl portion is eliminated, so that more accurate measurement can be performed. . The stored data of the measurement points of the stored water level and the stored water amount are calculated into a calibration curve using an interpolating relationship such as Lagrange interpolation, for example.

Next, the urination information measuring device 40 will be described with reference to FIG.
The urination information measuring device 40 is attached to a household Western-style toilet 31. This attachment can be easily performed by a patient as a subject. Next, the correlation coefficient k necessary for the measurement is set. In the present embodiment, the electronic recording medium 70 in which the relationship data between the urine flow time T and the urination amount R measured in advance in a medical institution is recorded. Input to the urination information measuring device 40. Accordingly, the correlation coefficient k is automatically calculated and stored from the relationship data between the urine flow time T and the urine output R.

  The correlation coefficient k may be input by inputting a numerical value with 10 keys or by wireless input using a mobile phone or the like. Alternatively, the correlation coefficient k may be directly input.

  The operation in actual use will be described. The subject operates the foot-operated activation switch 42 in the vicinity of the Western-style toilet 31 and activates the urination information measuring device 40. A urine flow detecting means 45 equipped with the radio wave sensor 1 starts transmitting microwaves and monitors the presence or absence of the urine flow that the subject urinates. The urine flow time is calculated from the urine flow detection time detected by the urination time calculation means 46. Next, the urine volume estimation means 47 estimates the urine volume from the urine flow time and the stored correlation coefficient k. At this time, the clock means 49 monitors the urination time as needed, and the estimated urine volume of the subject is stored in the urine record storage means 50 as time-series list data together with the time.

  The urination sensation information input unit 91 may be connected to the urination record storage unit 50. When creating a urination diary, medical personnel may be required to provide urination sensation information at the time of urination of the subject along with the time and amount of urination. General urination sensation information includes urinary urgency (how urgent was your urinary urgency), urinary leakage (have you been unable to endure?), And urination (actual urination) Do you feel it?)

  In addition, it is necessary to leave the bed for urination after going to bed, which leads to a decrease in quality of life (QOL), so a bed information input means 92 for inputting whether or not the subject is urinating during the bedtime is connected. You may do it. Actions are input at the time of the last urination when going to bed and at the first urination in the morning after getting up.

  Although it is assumed that the doctor has forgotten to enter the information requested by the doctor while looking at the list shown in FIG. 6 to be described later, the urination sensation information input means 91 and the bedtime information input means 92 are provided as described above. If the sensory information is input each time, the information requested by the doctor can be transmitted without omission.

  FIG. 6 is a table showing an example of a form in which an actually measured urination record is output. In this embodiment, this output form is called a urination diary. This urination diary is brought into a medical institution via an electronic medium such as a semiconductor memory card, and is presented to the doctor at the next diagnosis in a medical facility, so that the doctor can be judged. For example, even with urination records for about one week, if the form of this urination diary is used, the change trend of the urination state can be seen at a glance, so that the diagnosis of the doctor can be performed with high accuracy.

  On the paper strip of the urination diary, the number of urinations, the time of urination, the time of urine flow, the estimated amount of urination and the total amount of urine for each day are described for each measurement day. Although the use of urination records has been described for patients with urinary illness, it can also be used to manage dehydration, which can be easily recognized as a decrease in urine volume in the elderly. Moreover, when many users share, you may employ | adopt the structure which utilizes the personal authentication using RFID, for example.

  FIG. 7 is a perspective view of a urine output record creation device showing a second embodiment according to the present invention. A urine output record creation device 40 to be used at home is attached in front of the Western-style toilet 31. The above-described urine volume detection means and control unit are integrated and affixed to the ceramic surface of the Western-style toilet 31 via an adhesive member. In this case, since there is no floor-standing portion, this is a recommended configuration considering the cleanability.

  FIG. 8 is a measurement example in which the sound is measured when the urine flow exits the urethral orifice and reaches the pooled water. As a method of the urine flow detection means 45 incorporated in the urine output record creation device 40, not only a method of measuring the frequency transition due to the urine flow with the above-described radio wave sensor but also a sound pressure measurement of a falling sound caused by the urine flow using a microphone. There may be. Further, since the measured sound pressure level has a difference in frequency characteristics, it is possible to easily determine the urine flow rate. Also, if you urinate while flushing toilet toilet water to eliminate the excretion sound, it is impossible to measure the falling sound of the urine flow with a microphone. Thus, the falling sound of the urine flow can be discriminated. Therefore, such a configuration is also beneficial in view of user convenience. When a microphone is used, an expensive radio wave sensor, frequency analysis means, etc. are not required. Therefore, it can be expected that the urine volume recording creation system of the present invention is realized at low cost.

As a third embodiment, a method of detecting the movement of the free surface of the stored water in the toilet bowl that rises and rises due to the fall of the urine flow can be considered.
In the method for directly measuring the urine flow of the first embodiment described above, since the vector method of urine flow is different between standing urination and sitting urination, the detected urine flow value is reversed. In the method, there is no difference in the detection state between standing urination and sitting urination, and the urine flow time is detected as the time when there was a displacement. A method for measuring the urination time will be described in detail below with reference to FIGS. 9 and 10.

  FIG. 9 is a cross-sectional view of a urine output recording device showing a third embodiment according to the present invention. FIG. 10 is a measurement graph when the frequency displacement caused by the ripples on the free surface of the stored water and the water level rise is measured by the radio wave sensor.

  As shown in FIG. 9, a bowl surface 32 is formed inside the western-style toilet 31, and stored water 33 is stored inside. The urination information recording device 40 is configured to be hooked on the rim 31a of the Western-style toilet 31, and the radio wave 2 is irradiated from the radio wave sensor toward the vicinity of the free surface of the accumulated water 33. In this state, the urine excreted from the user enters the stored water 33 directly or indirectly through the bowl surface 32, and at this time, ripples occur on the free surface of the stored water 33. The wave is detected as shown in FIG.

  FIG. 10 shows how the output of the radio wave sensor changes with the series of operations during excretion by the user. In this way, urine flow due to urination, toilet paper input, sitting, and shaking of the stored water due to toilet flushing are detected as frequency displacement. Therefore, the urine flow time is detected as illustrated in the figure by starting the urination information recording device 40 prior to this urination and analyzing this waveform after the urination is finished and the measurement is finished. It will be.

  FIG. 11 is a plan view showing an embodiment of the urination supplementary information input means 90 according to the present invention, which includes both a urination sensation information input means 91 and a bedtime information input means 92. In the present embodiment, the urination information recording device 40 is configured by a remote controller connected by wire or wirelessly.

  Each time the subject urinates, the presence or absence of urinary urgency (how urgent is the urinary urgency) as urinary sensation information, the presence or absence of urine leakage (has he been unable to endure?), And urination (actual urination actually occurred) At that time, urination sense input switches 91a to 91c for inputting the urination sensation of presence / absence of presence / absence, and bedtime information input switches 92a and 92b for inputting bedtime information of going to bed or getting up Input according to the situation.

  In this embodiment, the urination sensation information input means 91 and the bedtime information input means 92 are both provided. However, the urination auxiliary information input means 90 in the present invention is the urination sensation information input means 91 or the bedtime information input means. It is sufficient that at least either one of 92 is provided.

  FIG. 12 is a table showing a second example of a form in which an actually measured urination record is output. Data input by the urination sensation information input unit 91 and the bedtime information input unit 92 are described together with measurement results such as the number of urinations, the time of urination, the time of urination, the estimated amount of urination, and the like. The * mark at the top of the data indicates that the subject was urinated during the bedtime. In the case of this example, it is indicated that the user has been woken up when urinating at 06:11 for the second time. Thus, since the urination at the time of waking up is the urine collected while sleeping, an asterisk (*) indicating that it is urination during sleeping is added, and this urination volume is included in the night urination volume. Therefore, the first urination at 02:23 indicates that urination occurs when the user leaves the bed for urination during bedtime. Further, since an asterisk (*) is given from the 22nd 2:00 urination of the 8th time, it indicates that a sleep input was made in order to go to bed at the 7th 21:11 urination. This seventh urination is included in the daytime urination which is the action time zone. The ninth time 23:20 indicates that he left the bed for urination while sleeping. If the night urination rate, which is the ratio of the night urine output to the night urine output or the total urine output, is automatically calculated, the medical institution can easily determine the QOL (quality of life) reduction of the subject.

  In addition, as a method for integrating the amount of urination at night, not only the method of counting in units of one day as shown in the present embodiment, but continuous sleeping may be regarded as the amount of urination at night. In the embodiment of FIG. 12, the third to seventh times on January 3 are the daytime urination amount, and the eighth time on January 3 to the first time on January 4 are the nighttime urine output amount. It may be possible to select and switch between totaling by this method or totaling by day as shown in FIG.

In addition, the urination diary is not written only at home. A urination diary may also be required for patients admitted to a medical institution. The same development can be applied to the operation / display unit 80 of the excretion information measuring device 60 provided in the medical institution. FIG. 13 is a plan view showing an example of the operation / display unit 80 provided in the medical institution. If the personal authentication operation means 83, the urination sensation information input means 84a, and the bedtime information input means 84b are arranged, the medical institution Even if it exists, the urination diary can be described easily for each individual.
