Description

  The present invention relates to a urine temperature measuring device that measures the urine temperature, which is the temperature of excreted urine excreted from the body of a subject, and a toilet system including the urine temperature measuring device.

  Traditionally, a person's body temperature has been created by physiological activities inside the body and has therefore been treated as an important indicator for judging health. And as a measuring method of body temperature, the measurement in the armpit, sublingual or rectum with a thermometer is performed. In addition to these measurement methods, since urine is accumulated in the body and its temperature is related to body temperature, urine excreted outside the body from the body's local excretion port instead of body temperature measurement (urination) Various urine temperature measuring devices have been proposed.

  For example, Patent Document 1 discloses that a urine temperature measuring means provided with a temperature sensing element such as a thermistor coated with a highly heat conductive metal or a heat insulating material is disposed on the inner wall of a toilet, and the subject uses this urine temperature measuring means. A urine temperature measuring device that receives urinary excretion and measures its temperature is disclosed.

As another example, there is also a urine temperature measuring device for measuring a urine temperature by providing a urine receiving container movably in a space in a toilet and providing a urine temperature measuring means in the urine receiving container. Conceivable.

  In general, the change in body temperature due to a change in health condition is often 1 ° C. or less, and a high-precision measurement of about 0.1 ° C. is required to make a detailed determination of the health condition based on a change in body temperature. The above-mentioned measurement under the armpit, the tongue and the rectum has problems in measurement reproducibility and measurement convenience. Therefore, the present inventors considered using urine temperature as body temperature information that can be easily measured and less burdened on the subject, and examined in detail the correlation between the body temperature of the subject and the temperature of urine excreted outside the body. .

  As a result, the temperature of the excreted urine immediately after being excreted from the subject's excretion port, that is, in the vicinity of the excretion port, is almost equal to the body temperature of the subject.

That is, since excretion urine released from the excretion port of the subject reaches the urine temperature measurement means placed at a position away from the excretion port, heat is transferred between the surrounding air (atmosphere), The urine temperature measured by the urine temperature measuring means is affected by this transfer phenomenon, and becomes a urine temperature immediately after being excreted from the excretion opening of the subject, that is, a temperature different from the urine temperature in the vicinity of the excretion opening.

  Furthermore, when the present inventors conducted confirmation tests in atmospheres of various temperatures, the degree of influence of this transfer phenomenon cannot be ignored with respect to the temperature fluctuation range of excreted urine due to changes in the physical condition of the subject to be measured by the present invention. It was confirmed that it was large. The degree of influence depends on the exchange of heat, so the temperature difference between excreted urine and the atmosphere, the length (distance) of the route through which excreted urine passes (hereinafter referred to as “urine trajectory”), and the release of excreted urine It was found that it varies depending on speed, flow rate, etc.

[1. First Embodiment]
[1.1 Toilet system configuration]
Hereinafter, a first embodiment of a urine temperature measuring device to which the present invention is applied will be specifically described with reference to the drawings. FIG. 1 is an external perspective view showing a urine temperature measurement device and a toilet system provided with the urine temperature measurement device according to the present embodiment, and FIG. 2 is a side sectional view of the toilet bowl provided in the toilet system shown in FIG. FIG. 3 is an external perspective view of the remote control device provided in the urine temperature measuring device shown in FIG.

  As shown in FIGS. 1 and 2, the toilet system 1 includes a toilet 3 installed in a toilet booth 2 and a urine temperature measuring device 4 attached to the toilet 3. In the present embodiment, the urine temperature measuring device body 6 of the urine temperature measuring device 4 incorporates a local cleaning device 9 (see FIG. 4) for cleaning a local part of the human body. Therefore, as will be described later, the remote control device 5 has a function of operating not only the urine temperature measuring device 4 but also the toilet 3 and the local cleaning device 9.

[1.1.1 Overview of urine temperature measurement device]
The urine temperature measuring device 4 measures the excretion urine temperature, which is the temperature of excreted urine excreted outside the body from the excretion port D of the subject P. As shown in FIGS. The urine temperature measuring device main body 6 placed on the urine temperature measuring device main body 6, the toilet seat 7 provided rotatably on the urine temperature measuring device main body 6, and the toilet lid 8 provided on the urine temperature measuring device main body 6 so as to be rotatable. And a remote control device 5 provided on the wall surface of the toilet.

  The remote control device 5 includes not only the function of the urine temperature measuring device main body 6 but also the functions of the local washing device 9 and the toilet 3 as well as a group of operation buttons for the subject to instruct their execution, And a display unit for displaying results and various messages.

  Although not shown in the figure, the urine temperature measuring device main body 6 houses various devices for improving the convenience of the toilet 3 such as a local cleaning device and a toilet seat heating device for automatically cleaning the local area of the subject P. It is arranged so that each function such as a local cleaning function and a toilet seat heating function can be executed.

  The urine temperature measuring device main body 6 includes a temperature measuring unit 10 for measuring the temperature of urine excreted by the subject P and the environmental temperature in the present invention, and a urination (not shown) for measuring the urination distance of the subject in the present invention. A distance measurement unit and a urine flow rate measurement unit (not shown) for measuring the urine flow rate, which is the amount of urination per unit time of the subject in the present invention, are provided.

[1.1.2 Details of urine temperature measuring device]
The temperature measurement unit 10 is connected to the support box 16 provided in the rim 3a of the toilet bowl 3 and having a built-in swing arm drive unit 22 (see FIG. 4), and the swing arm drive unit 22 provided in the support box 16 at one end. It has a swing arm 18 that is movably supported, a urine receiving container 20 connected to the other end of the swing arm 18, and a temperature sensor 11 provided inside the urine receiving container 20.

  Here, the temperature sensor 11 has a configuration in which a thermistor, whose resistance value changes with temperature, is sealed in a protective tube as a temperature sensitive body, and the protective tube is fixed to the urine storage part of the urine receiving container 20. It has a structure.

  Then, the temperature measurement unit 10 rotates the swing arm 18 to advance the urine receiving container 20 from the support box 16 to the position of receiving the urine excreted from the subject P on the ball 3b side of the toilet bowl 3, The urine excreted from P is received in the urine receiving container 20, and the temperature of the urine is measured by the temperature sensor 11 provided in the urine receiving container 20. It is comprised so that it may house.

  In addition, a temperature sensor cleaning unit 24 (see FIG. 4) is provided inside the support box 16, and the swing arm 18, the urine receiving container 20, and the temperature sensor 11 are supported after the urine temperature is measured. In the state accommodated in the temperature sensor 16, it is cleaned by the temperature sensor cleaning unit 24.

  The temperature of the urine received by the temperature sensor 11 configured as described above is excreted from the local excretion port D of the subject P because the distance between the excretion port D of the subject P and the temperature sensor 11 is relatively long. Until the received urine reaches the temperature sensor 11, the temperature is different from the urine temperature (excretion urine temperature) immediately after being excreted from the excretion opening D under the influence of temperature due to various influencing factors. For example, in a toilet room environment where the present embodiment to which the present invention is applied is installed, the temperature in the bowl of the toilet 3 to be urinated is often lower than the temperature of normal urination. By doing so, the temperature of urine falls below the excretion urine temperature.

  That is, the measured value of the urine temperature received by the temperature sensor 11 (hereinafter referred to as the measured value of the temperature sensor 11) is the urine temperature immediately after being excreted from the excretion port D, which is the measurement object of the present invention. Is different.

  Therefore, in order to eliminate the influence on the temperature sensor 11 due to such influence factors, the urine temperature measurement device 4 according to the present embodiment obtains the influence of acquiring the states of these influence factors that affect the measurement values of the temperature sensor 11. Based on the factor state acquisition means and the state of the influence factor acquired by the influence factor state acquisition means, a temperature correction amount for the measurement value of the temperature sensor 11 is calculated, and the measurement value of the temperature sensor 11 is corrected by this temperature correction amount. By doing so, it has a urination temperature correction means for calculating the excretion urine temperature.

  Therefore, the urine temperature measuring device 4 also measures the ambient temperature in the vicinity of the urination locus by measuring the output value of the temperature sensor 11 immediately before the subject's urine starts to hit before starting the urine temperature measurement to obtain the corresponding temperature. It is configured as follows. That is, the temperature sensor 11 functions as a urine temperature measuring unit, and also functions as an influencing factor state acquiring unit that measures an environmental temperature that is an air temperature in the vicinity of the urination locus as an influencing factor in the present invention.

  In this way, the temperature sensor 11 which is the urine temperature measuring means disposed in the ball 3b also measures the environmental temperature as an influencing factor in the present invention, thereby providing a temperature measuring means for separately measuring the environmental temperature. There is no need to provide it, and the cost of the urine temperature measuring device can be reduced. It is also possible to more accurately determine the amount of influence on the urine temperature measurement value due to the urination atmosphere. The reason will be described below.

  In the case of the toilet system 1 in the present embodiment, the space through which the excreted urine released by the subject P passes is a closed space surrounded by the balls 3b of the toilet bowl 3, the toilet seat 7, and the buttocks of the subject P, and this closed space. The temperature of the room may be considered to be substantially the same as the room temperature in the toilet booth during standby when the toilet system 1 is not used, but may be different from the room temperature in the toilet booth as described below.

  That is, since the subject P is seated on the toilet seat 7, the function of drying by warm air after washing the local area after excretion (hereinafter referred to as hot air drying function) is measured by measuring the urine temperature. For example, when the apparatus main body 6 is provided, the subject before the subject P is affected by the residual heat of the operation after using the drying function.

  Thus, when the subject P uses the apparatus immediately after the subject in front of the subject P uses the apparatus, the temperature of the closed space is much larger than the room temperature of the toilet booth other than the closed space, for example. The temperature is extremely high. Therefore, as in this embodiment, it is more stable and accurate to adopt the temperature of the air in the vicinity of the urination trajectory as the environment temperature as the temperature of the closed space than the room temperature of the toilet booth as the environment temperature. The urine temperature can be obtained. Further, the output characteristics of the temperature sensor 11 which is the urine temperature measuring means are also affected by the ambient temperature, but this influence is reduced, and more accurate measurement is possible.

  Further, since the temperature distribution is not uniform even in the closed space, if the temperature sensor 11 is provided on the urine locus as a position in the vicinity of the urine locus as in the present embodiment, at least the temperature sensing part is the subject (this In the embodiment, it is installed in an atmosphere closer to the atmosphere of excreted urine), and more accurate measurement is possible.

  As a result of the diligent research by the present inventors, an influencing factor other than the environmental temperature, which is the air temperature in the vicinity of the urination locus described above, is urination, which is the distance from the position of the excretion opening D of the subject P to the position of the temperature sensor 11. It has been found that the distance and the urine flow rate, which is the amount of urination per unit time, have a great influence on the measurement value of the temperature sensor 11 described above.

  Therefore, the urine temperature measuring device 4 according to the present embodiment is a distance sensor 12 that detects the distance to the subject P, and a water level that measures the water level stored in the ball 3b, as an example of an influence factor state acquisition unit. The urine temperature measuring device main body 6 includes a control unit 40 (see FIG. 4) that controls the operation of the entire urine temperature measuring device 4 and also functions as a urine temperature correcting means. ing. A specific configuration of the control unit 40 will be described in detail later.

  The distance sensor 12 is provided in the support box 16, transmits a high-frequency electromagnetic wave toward the subject P, receives a reflected wave reflected by the subject P, and measures the distance to the subject P. It consists of a pulse radar.

  When the urine temperature measuring device 4 measures the distance to the subject P by the distance sensor 12, the urine temperature measuring device 4 is based on the distance to the subject P and the distance between the preset distance sensor 12 and the temperature sensor 11. The urination distance as the influence factor state in the present invention is calculated and acquired.

  The water level sensor 14 is provided at the bottom of the bowl 3b of the toilet bowl 3, and includes a pressure-sensitive element that converts a change in water pressure into an electrical signal.

  The urine temperature measuring device 4 measures the water level in the ball 3b over time by the water level sensor 14, and based on the temporal change of the water level, the urine flow rate, which is the amount of change in urine per unit time, is obtained. It is comprised so that it may calculate and acquire as a state of the influence factor in this invention.

  Then, the urine temperature measuring device 4 calculates the temperature correction amount for the measurement value of the temperature sensor 11 based on the environmental temperature, the urination distance, and the urine flow rate, which are the states of the influence factors in the present invention obtained by the above method. The excretion urine temperature is calculated by calculating and correcting the measured value of the temperature sensor 11 by the temperature correction amount.

  The urine temperature measuring device main body 6 includes a communication unit 36 (see FIG. 4) that functions as an operation signal receiving unit that receives various operation signals transmitted from the remote control device 5.

  The urine temperature measuring device main body 6 is configured to execute an operation corresponding to each operation signal based on various operation signals received from the remote control device 5 via the communication unit 36.

The display unit 52 operates according to the control of the control unit 50, and the toilet system 1 is provided in the liquid crystal display unit 5f. Character information indicating the setting states of various functions and the urine temperature measurement result by the urine temperature measuring device 4 is displayed.

  The operation button unit 54 is buttons that are operated by the subject P to operate various functions of the toilet system 1. Specifically, the operation button unit 54 includes a plurality of toilet operation buttons 5 b and a local cleaning device operation button. 5c, a urine temperature measurement execution button 5d, and an individual selection button 5e, and inputs signals corresponding to these operations to the control unit 50.

  Then, when a signal is input from the operation button unit 54, the control unit 50 executes a program corresponding to the signal, thereby operating the communication unit 58 to correspond to each button on the urine temperature measuring device main body 6. Control is performed to transmit an execution signal of the performed operation.

  For example, when a signal operated from the individual selection button 5e in the urine temperature measurement device 4 is input, the control unit 50 determines whether or not personal information corresponding to the signal is stored in the EEPROM 45. When it is determined that the personal information corresponding to the EEPROM 45 is stored, the control unit 50 creates personal information display data based on the corresponding personal information and sends it to the display unit 52 so that the subject P can confirm the contents. To display.

  Thereafter, when the subject P operates the urine temperature measurement execution button 5d, the control unit 50 activates the communication unit 58 to transmit a measurement operation execution signal including personal information to the urine temperature measurement device body 6. Do.

  The setting button unit 56 inputs a signal corresponding to the operation of the personal information setting button 5g by the subject P to the control unit 50 in order to customize and set various functions and operations provided in the toilet system 1. It is.

  That is, when the signal from the “registration” button in the setting button 5g is input to the operation signal sent from the setting button unit 56, the control unit 50 sets the operation mode of the toilet system 1 to the personal information registration mode. Set to. Then, after the personal information registration mode is set, the control unit 50 receives a signal input from the personal information setting button 5g other than the “registration” button or the selected personal selection button 5e from the setting button unit 56. Control for creating personal information data and storing it in the EEPROM 45 is performed.

  When this personal information registration mode is set in the urine temperature measuring device 4, the control unit 50 stores the input gender and age of the subject P in the EEPROM 45 as personal physical information in association with the personal selection button 5e. Take control.

  Further, the control unit 50 sets a signal from the personal information setting button 5g other than the “registration” button when the signal from the “registration” button is not input, that is, when the normal operation mode is set in the toilet system 1. When sent from the button unit 56, an operation execution signal corresponding to the operation of the setting button 5g is sent to the toilet 3, the local cleaning device, and the urine temperature measuring device main body 6 constituting the toilet system 1 by operating the communication unit 58. Control to send.

  When the urine temperature measuring device 4 is in this normal operation mode, the control unit 50 operates the personal information setting button 5g other than the “registration” button to specify the position of the urine receiving container 20, for example. 50 controls the operation of the communication unit 58 to transmit an operation execution signal corresponding to the operation of the setting button 5g to the urine temperature measuring device main body 6.

  The communication unit 58 includes a transmission / reception circuit that transmits and receives various signals among the toilet bowl 3, the local cleaning device, and the urine temperature measurement device main body 6 constituting the toilet system 1, and transmits an operation execution signal based on an operation by the subject P. By transmitting to each device, each device operates according to the control of the control unit 50. Moreover, when the communication part 58 receives the signal transmitted from these each apparatus, it will transmit to the control part 50 via a bus | bath.

  In this case, in the urine temperature measurement device 4, the communication unit 58 measures the urine temperature measurement via the communication unit 36 when the subject P performs a pressing operation on the urine temperature measurement execution button 5 d. A measurement result display signal transmitted from the urine temperature measurement device main body 6 via the communication unit 36 is received after the measurement is completed.

[1.3 Correction by urination temperature correction means]
Next, correction by the urine temperature correcting means of the urine temperature measuring device 4 will be described with reference to FIGS. In the following description, the urination temperature immediately after being released from the excretion port D of the subject P is 37 ° C. which is substantially equal to the body temperature of the subject P, and the urination distance when the subject P is a male is 50 mm, Assume that the urination distance is 100 mm when is a woman.

  FIG. 6 shows, as an example, the difference between the urination temperature with respect to the urination distance and the measured value of the urine temperature by the temperature sensor 11 (hereinafter referred to as measurement error of the temperature sensor 11) when the urine flow rate is 15 ml / s. It is explanatory drawing which showed the relationship. As shown in FIG. 6, when attention is paid to the urination distance, for example, when the environmental temperature measured by the temperature sensor 11 is 20 ° C., the urination distance is 0 mm, 50 mm (when the subject is a male), 100 mm (when the subject is The measurement error of the temperature sensor 11 tends to increase as 0, ΔT50, and ΔT100, respectively. The same tendency is shown when the environmental temperature measured by the temperature sensor 11 is 5 ° C. or 35 ° C.

  That is, as the urination distance increases, the time until the urine discharged from the excretion port D of the subject P reaches the temperature sensor 11 increases, and during that time, the amount of heat released from the urine to the surrounding air increases. The measurement error of the temperature sensor 11 increases.

  Also, as shown in FIG. 6, when attention is paid to the environmental temperature, for example, when the urination distance is 50 mm (when the subject is a male), the environmental temperature decreases to 35 ° C., 20 ° C., and 5 ° C. Accordingly, the measurement errors of the temperature sensor 11 tend to increase like ΔTa50, ΔT50, and ΔTb50, respectively. The same tendency is shown when the urination distance is 100 mm (when the subject is a woman).

  That is, as the environmental temperature decreases, the amount of heat released from the urine to the surrounding air before the urine discharged from the excretion port D of the subject P reaches the temperature sensor 11 increases. The measurement error increases.

  Thus, although the measurement value of the temperature sensor 11 includes a measurement error depending on the urination distance and the environmental temperature, it has been found that the measurement error has a certain relationship with the urination distance and the environmental temperature. In other words, if the urination distance and the environmental temperature are measured, the measurement error of the temperature sensor 11 by each is uniquely determined. Therefore, the excretion urine temperature can be calculated by adding the measurement error of the temperature sensor 11 to the measurement value of the temperature sensor 11 as a temperature correction amount with respect to the measurement value of the temperature sensor 11. For example, by designing in advance a correction formula that approximates the relationship between the urination distance and the environmental temperature and the temperature correction amount as a linear graph of the linear expression shown in FIG. 6, and substituting the urination distance and the environmental temperature into this correction formula. The temperature correction amount can be calculated, and the excretion urine temperature can be calculated by adding the temperature correction amount to the measured value of the temperature sensor 11.

  By the way, in FIG. 6, the measurement error of the temperature sensor 11 when the urine flow rate is 15 ml / s has been described as an example. However, the measurement error of the temperature sensor 11 may be influenced by the urine flow rate. .

  FIG. 7 is an explanatory diagram showing the relationship between the measurement error of the temperature sensor 11 with respect to the urine flow rate when the urination distance is 50 mm (when the subject is a male) and the environmental temperature is 20 ° C. as an example. When the urination distance is 50 mm and the environmental temperature is 20 ° C., the temperature correction amount for the urination distance and the environmental temperature is ΔT50 shown in FIG.

  As shown in FIG. 7, when the urine flow rate is equal to or higher than a predetermined value (here, 12 ml / s), the measurement error of the temperature sensor 11 is a constant value ΔT50, which is influenced by the urine flow rate. The temperature correction amount ΔT50 calculated with respect to the urination distance and the environmental temperature can be directly adopted as the temperature correction amount.

  However, when the urine flow rate is smaller than a predetermined value (here, 12 ml / s), the measurement error of the temperature sensor 11 tends to increase as the urine flow rate decreases. For this reason, the temperature correction amount ΔT50 calculated from the relationship shown in FIG. 6 cannot be adopted as a correct temperature correction amount.

  Therefore, when the urinary flow rate is smaller than a predetermined value (here, 12 ml / s), for example, as shown in FIG. 7, the relationship between the urinary flow rate and the measurement error of the temperature sensor 11 is expressed by a linear expression. A correct temperature correction amount can be calculated by designing a correction formula approximated as a linear graph in advance and substituting the urine flow rate into the correction formula.

  In the urine temperature measuring device 4 according to the present embodiment, the urine temperature correcting means calculates a temperature correction amount for the measurement value of the temperature sensor 11 based on the environmental temperature, the urination distance, and the urine flow rate, and the temperature sensor 11, the excretion urine temperature in the present invention, which is the urine temperature immediately after excretion, is estimated by correcting the measurement value of the urine temperature by 11 with the temperature correction amount.

  Specifically, in the urine temperature measuring device 4, temperature correction amount data using the environmental temperature, distance, and urine flow rate as parameters are stored in advance in the ROM 32, and the urine temperature correction means reads the temperature correction read from the ROM 32. By substituting the environmental temperature, distance, and urine flow rate into the quantity data, a temperature correction amount for the measurement value of the temperature sensor 11 is calculated, and the calculated temperature correction amount and the measurement value of the temperature sensor 11 are added. Then, the correction is made and the excretion urine temperature is estimated.

  Here, the temperature correction amount data using the environmental temperature, distance, and urine flow rate as parameters is data including a correction formula, a correction table, etc. using the environmental temperature, urination distance, and urine flow rate as parameters. The correction formulas corresponding to the relationships shown in FIGS. 6 and 7 are also included in this.

[1.4 Operation of urine temperature measuring device and remote control device]
Next, an example of the operation for measuring the urine temperature using the urine temperature measuring device 4 and the remote control device 5 will be described in detail with reference to FIGS. FIG. 8 is a flowchart showing the control executed by the control unit 40 of the urine temperature measuring device 4, and FIG. 9 is a flowchart showing the control executed by the control unit 50 of the remote control device 5.

(Processing performed by the controller of the urine temperature measuring device)
As shown in FIG. 8, when the control unit 40 of the urine temperature measuring device main body 6 receives the urine temperature measurement execution signal sent from the remote control device 5 in step S1, the subject is based on the personal information signal included therein. The individual specifying process for specifying is performed, and the process proceeds to step S2.

  In step S <b> 2, the control unit 40 determines whether or not a personal measurement mode selection signal indicating that the individual selection button 5 e has been operated by the subject has been received from the remote control device 5.

  In this process, if the control unit 40 determines that the personal measurement mode selection signal has been received (step S1: Yes), the process proceeds to step S3, and if it is determined that it has not been received (step S2: No), the process To step S11.

In step S3, the control unit 40 operates the swing arm driving unit 22 to rotate the swing arm 18 from the standby position to the urine receiving position, thereby positioning the urine receiving container 20. At this time, because of the individual measurement mode, the urine container 20 is positioned at an individual position registered by the subject. When this process ends, the control unit 40 moves the process to step S4.
In step S <b> 11, the control unit 40 operates the swing arm driving unit 22 to rotate the swing arm 18 from the standby position to the urine receiving position, thereby positioning the urine receiving container 20. At this time, because of the general measurement mode, the urine container 20 is positioned at the standard position. When this process ends, the control unit 40 moves the process to step S4.

  In step S4, the control unit 40 performs an environmental temperature measurement process. Specifically, among the output signals transmitted from the temperature sensor 11, the control unit 40 outputs the environmental temperature information as the output signal from when the subject P starts to urinate until the urination starts to hit the temperature sensor 11. Therefore, the environmental temperature is calculated from the output signal, and the value is stored in the predetermined area of the RAM 34 as the environmental temperature in the urine temperature measurement. When this process ends, the control unit 40 moves the process to step S5.

  In step S5, the control unit 40 executes a process of measuring the urination distance and the urine flow rate. Specifically, when receiving an output signal including distance information to the subject P transmitted from the distance sensor 12, the control unit 40, the distance information to the subject P, the distance sensor 12 read from the ROM 32, and the temperature sensor 11. The urination distance is calculated based on the distance information between the urine distance and the urination distance in the urine temperature measurement in a predetermined area of the RAM 34. At the same time, the control unit 40 receives information on the water level in the ball 3b transmitted from the water level sensor 14 every moment, and calculates the water amount at that time using a water level-water amount calibration curve obtained in advance. By continuously performing this process during urination of the subject P, the urine flow rate, which is the amount of urination per unit time, is calculated and stored in a predetermined area of the RAM 34 as the urine flow rate in this urine temperature measurement.

  In step S6, the control unit 40 executes a urine temperature measurement process. Specifically, when the subject starts to urinate toward the urine receiving container 20 provided at the tip of the swing arm 18 and urination starts to hit the temperature sensor 11 provided in the urine receiving container 20, the temperature sensor 11 The signal transmitted from the urine includes urination temperature information. The control unit 40 receives the output signal including the temperature information transmitted from the temperature sensor 11, thereby calculating the urine temperature and storing it as a urination temperature in a predetermined area of the RAM 34. When this process ends, the control unit 40 moves the process to step S7.

  In step S7, the control unit 40 performs a temperature correction amount calculation process. Specifically, the control unit 40 reads temperature correction amount data using the environmental temperature, distance, and urine flow rate as parameters from the ROM 32, and stores the temperature correction amount data in the RAM 34 in step S4 and step S5. By substituting the environmental temperature, the urination distance, and the urine flow rate as influential factors in the urine temperature measurement in the present invention and the urination temperature stored in step S6, the measured value of the temperature sensor 11 in this urine temperature measurement. A temperature correction amount for the urination temperature is calculated. When this process ends, the control unit 40 moves the process to step S8.

  In step S8, the control unit 40 executes a temperature correction process for the urination temperature. Specifically, the control unit 40 performs correction by adding the temperature correction amount calculated in step S7 to the measured value of the temperature sensor 11 stored in the RAM 34 in step S5, and calculates excretion urine temperature. When the excretion urine temperature is calculated, the control unit 40 generates a result display signal which is a control signal for displaying the measurement result in association with the individual subject on the remote controller 5 based on the excretion urine temperature and the subject information. When this process ends, the control unit 40 proceeds to step S9.

  In step S9, the control unit 40 executes a result display signal transmission process. Specifically, control unit 40 performs a process of transmitting the result display signal generated in step S8 to remote control device 5. When this process ends, the control unit 40 moves the process to step S10.

  In step S10, the control unit 40 performs a urine container storage cleaning process. Specifically, the control unit 40 operates the swing arm driving unit 22 to rotate the swing arm 18 from the urine receiving position to the standby position, and stores the urine receiving container 20 and the temperature sensor 11 in the support box 16. . Thereafter, the control unit 40 operates the temperature sensor cleaning unit 24 to clean the swing arm 18, the urine receiving container 20, and the temperature sensor 11, and then returns the process to step S1.

(Processing performed by the control unit of the remote control device)
Next, processing performed by the remote control device 5 in the present embodiment will be described below.
As shown in FIG. 9, in step S <b> 20, the control unit 50 of the remote control device 5 first determines whether a result display signal has been received from the urine temperature measuring device body 6.

  In this process, if the control unit 50 determines that the result display signal has been received from the urine temperature measurement device main body 6 (step S20: Yes), the process proceeds to step S21, and the result display signal is output from the urine temperature measurement device main body 6. Is determined not to be received (step S20: No), the process proceeds to step S22.

  In step S21, the control unit 50 performs a result display process. That is, the control unit 50 operates the display unit 52 to display information indicating the excretion urine temperature as a urine temperature measurement result by the urine temperature measurement device 4 on the liquid crystal display unit 5f. When this process ends, the control unit 50 returns the process to step S20.

  In step S22, the control unit 50 determines whether or not the urine temperature measurement execution button 5d has been pressed, and determines that the urine temperature measurement execution button 5d has been pressed (step S22: Yes), the urine without specifying the subject. The process proceeds to step S23 as a general measurement mode for performing temperature measurement, and if it is determined that the urine temperature measurement execution button 5d has not been pressed (step S22: No), the process proceeds to step S24.

  In step S23, the control unit 50 executes a urine temperature measurement execution signal transmission process as a general measurement mode. That is, the control unit 50 transmits a urine temperature measurement execution signal for the urine temperature measurement device 4 to execute the general measurement mode to the urine temperature measurement device 4. When this process ends, the control unit 50 returns the process to step S20.

  In step S24, the control unit 50 determines whether or not the individual selection button 5e has been pressed. If the control unit 50 determines that the personal selection button 5e has been pressed (step S24: Yes), the subject is identified and urine temperature is measured. The process proceeds to step S25 as the individual measurement mode, and if it is determined that the individual selection button 5e has not been pressed within a predetermined time (step S25: No), the process returns to step S20.

  In step S25, the control unit 50 determines whether or not personal information is stored (registered) in the RAM 46. If it is determined that personal information is registered (step S25: Yes), the process proceeds to step S28. If it is determined that personal information is not registered (step S25: No), the process proceeds to step S26.

  If it is determined in step S25 that the personal information necessary for executing the urine temperature measurement in the personal measurement mode is not registered, the control unit 50 performs an operation for inputting / registering the personal information in step S26. It is determined whether or not the personal information setting button 5g is pressed. If it is determined that the personal information setting button 5g is pressed (step S26: Yes), the process proceeds to step S27 to register the personal information input by the personal information setting button 5g. Execute the process. That is, the control unit 50 stores (registers) in the RAM 46, as personal information, information including at least the gender and age of the subject P that is input when the operation button unit 54 and the setting button unit 56 are operated by the subject P. Then, the process proceeds to step S29.

  In step S27, when there are a plurality of subjects, any personal selection button 5e and setting button 5g are operated to associate personal information including at least gender and age of each subject with each of the personal selection buttons 5e. And stored in the RAM 46. For example, as shown in FIG. 3, among the individual selection buttons 5e, a 45-year-old man is associated with the first button, a 44-year-old woman is associated with the second button, and a 15-year-old is associated with the third button. Like a man or the like, personal information is stored in the RAM 46. When this process ends, the control unit 50 moves the process to step S29.

  In step S28, the control unit 50 displays the personal information read from the RAM 46 on the liquid crystal display unit 5f, and the process proceeds to step S29.

  In step S29, the control unit 50 determines whether or not the urine temperature measurement execution button 5d has been pressed. If it is determined that the urine temperature measurement execution button 5d has been pressed, the control unit 50 proceeds to step S30 and executes urine temperature measurement execution signal transmission processing. In this case, unlike the urine temperature measurement execution signal transmission process in step S23 described above, the control unit 50 allows the urine temperature measurement device 4 to execute the individual measurement mode to the urine temperature measurement device body 6. A urine temperature measurement execution signal including personal information of the subject is transmitted. When this process ends, the control unit 50 returns the process to step S20.

  As described above, according to the urine temperature measuring device 4 according to the present embodiment, the temperature sensor 11 is based on the environmental temperature, the urination distance, and the urine flow rate, which are influential factors affecting the measurement value of the temperature sensor 11. By calculating the temperature correction amount for the measurement value and correcting the measurement value of the temperature sensor 11 by the temperature correction amount, the excretion urine temperature is calculated, so the distance between the temperature sensor 11 and the excretion port of the subject is relatively long. Even if they are separated from each other, an accurate urine temperature can be measured without being affected by the influencing factors.

  Note that the urine temperature measurement device 4 of the present embodiment is configured to calculate the temperature correction amount for the measurement value of the temperature sensor 11 based on the environmental temperature, the urination distance, and the urine flow rate. I can't. Depending on the measurement accuracy required for the urine temperature, the configuration of the device, and the like, for example, the measurement of the temperature sensor 11 based on any influence factor or combination of a plurality of influence factors among the environmental temperature, the urination distance, and the urine flow rate. A temperature correction amount for the value may be calculated.

  As described above, some of the embodiments of the present invention have been described in detail with reference to the drawings. However, these are merely examples, and various embodiments can be made based on the knowledge of those skilled in the art including the aspects described in the section of the disclosure of the invention. The present invention can be implemented in other forms that have been modified or improved.

  For example, in the present embodiment, the temperature sensor 11, the distance sensor 12, and the water level sensor 14 are provided, and the control unit 40 operates the temperature sensor 11, the distance sensor 12, and the water level sensor 14 as influence factor state acquisition means. Thus, the environmental temperature, the urination distance, and the urine flow rate are respectively calculated and acquired. However, in addition to such a configuration, an image analysis apparatus may be provided at an appropriate place.

  In this configuration, a temperature correction amount calculation table corresponding to the cross-sectional area of urine excreted by the subject is stored in advance in the ROM 32 of the control unit 40.

  By configuring in this way, the control unit 40 calculates the image by analyzing the cross-sectional area of the urine excreted by the subject by operating the image analysis device as the influence factor state acquisition unit. Thereafter, the control unit 40 substitutes the cross-sectional area of the urine excreted by the subject into the temperature correction amount calculation table corresponding to the cross-sectional area of the urine excreted by the subject, read from the ROM 32, as the urine temperature correcting means. The temperature correction amount for the measurement value of the temperature sensor 11 is calculated.

  In step S103, the control unit 150 determines whether any of the individual selection buttons 5e has been pressed. If the control unit 150 determines that the personal selection button 5e has been pressed (step S103: Yes), the process proceeds to step S104. If it is determined that the individual selection button 5e has not been pressed within the predetermined time (step S103: No), the process returns to step S101.

  In step S104, the control unit 150 determines whether or not personal physical information corresponding to the type (number) of the selected personal selection button 5e is stored (registered) in the storage unit 151, and the personal physical information is registered. If it is determined that it has been performed (step S104: Yes), the process proceeds to step S105, and the personal physical information stored in the storage unit 151 is displayed on the liquid crystal display unit 5f. At this time, a message prompting confirmation of the display contents and the next operation to be operated by the subject P is displayed on the liquid crystal display unit 5f, and the process proceeds to step S109.

  When it is determined in step S104 that personal physical information is not registered (step S104: No), in step S106, the control unit 150 determines whether or not the “registration” button of the personal information setting button 5g has been pressed. If it is determined that it has been pressed (step S106: Yes), the operation mode is set to the personal information registration mode, and a message prompting the input operation of various personal information including the personal physical information of the subject P is displayed on the liquid crystal display. The information is displayed on the part 5f, and the process proceeds to S107. In the following, a registration process of personal physical information related to the present invention among the various personal information described above will be described.

  In step S107, after receiving a setting signal related to personal physical information by operating the personal information setting button 5g of the subject P performed according to the display content of the liquid crystal display unit 5f, personal information registration processing is executed in step S108. That is, the control unit 150 selects personal information including at least the gender and age of the subject P as personal physical information, which is input by the subject P operating the personal selection button 5e and the personal information setting button 5g. A process of storing (registering) in the storage unit 131 in correspondence with the type (number) of the individual selection button 5e is performed.

  That is, when there are a plurality of subjects, for example, as shown in FIG. 3, among the individual selection buttons 5e, a 45-year-old man is associated with the first button and a 44-year-old woman is associated with the second button. Personal physical information is stored in the storage unit 131 like a 15-year-old man or the like in association with the third button. When this process ends, the control unit 50 moves the process to step S109.

  In step S109, the control unit 50 determines whether or not the urine temperature measurement execution button 5d (the “measurement” button in FIG. 3) has been pressed. If it is determined that the button has been pressed, the control unit 50 proceeds to step S110 and selects in step S103. A urine temperature measurement execution signal including a personal information signal including the type (number) of the personal selection button 5e and the personal physical information and a control signal for executing the urine temperature measurement operation; The transmission process of this urine temperature measurement execution signal to the main body 106 is executed. When this process ends, control unit 150 returns the process to step S101.

[2.3.2 Operation of urine temperature measuring device main body]
Next, the flow of the control operation performed by the control unit 140 of the urine temperature measuring device main body 106 will be described below with reference to FIG.

In step S131, when the control unit 140 receives the urine temperature measurement execution signal sent from the remote control device 105 via the communication unit 36, the control unit 140 executes personal information specifying processing.
The personal information specified by this personal information specifying process is specified in the following two types.
That is, the control unit 140 specifies the gender and age of the subject P included in the urine temperature measurement execution signal as personal physical information, the type (number) of the selected personal selection button 5e, time information at that time, and the like Are stored as personal data management information in the storage unit 141 in association with each other. Therefore, at this time, the control unit 140 also functions as an influence factor acquisition unit in the present invention.

  Also, by this processing, information such as measurement data for each measurement of a plurality of subjects is stored in association with the type (number) of the individual selection button 5e, so that history management of measurement data for a plurality of subjects is also possible. It becomes. When this process ends, the process moves to a step S132.

In step S <b> 132, the control unit 140 operates the swing arm driving unit 22 to rotate the swing arm 18 from the standby position to the urine receiving position, thereby positioning the urine receiving container 20. At this time, based on the personal physical information of the subject P specified in step S131, the position of the urine container corresponding to gender and age is specified, and the urine container position setting table stored in the storage unit 141 is referred to. By doing so, the urine receiving container 20, in other words, the temperature sensor 11, is fixed at a position optimal for the position of the excretion opening D of the subject P. When this process ends, the control unit 140 shifts the process to step S133.

  In step S133, the control unit 140 performs a temperature measurement process by the same process as in step S4, and stores the measured value at this time as the environmental temperature. At this time, before the subject P starts excretion, it is assumed that the urine receiving container 20 is not yet urinated. When this process ends, the controller 140 shifts the process to step S134.

  In step S134, when the subject P starts excretion and the urine receiving container 20 is urinated, the control unit 140 executes the urine temperature measurement process by the same process as in step S6. The measured value is stored as the urination temperature. When this process ends, the process moves to a step S135.

  In step S135, the control unit 140 executes a temperature correction amount calculation process according to the personal body information specified and stored in step S131. Specifically, the control unit 140 calculates the temperature correction amount by inputting the gender and age of the subject P specified in step S131 into a temperature correction amount calculation table stored in advance according to personal physical information. The temperature correction amount is stored as the first temperature correction amount. When this process ends, the control unit 140 shifts the process to step S136.

  In step S136, the control unit 140 executes a temperature correction amount calculation process corresponding to the environmental temperature. Specifically, a temperature correction amount table using the environmental temperature and the urination temperature as parameters is read from the storage unit 141, and the environmental temperature stored in step S133 and the urine temperature stored in step S134 are stored in this temperature correction amount table. , The second temperature correction amount for the measured value of the urination temperature of the temperature sensor 11 is calculated, and this temperature correction amount is stored as the second temperature correction amount. When this process ends, the control unit 140 shifts the process to step S137.

  In step S137, the control unit 140 performs excretion urine temperature calculation processing. Specifically, the temperature correction for the measured value of the urination temperature of the temperature sensor 11 is performed by adding the first temperature correction amount calculated in step S135 and the second temperature correction amount calculated in step S136. Calculate the amount. Thereafter, the control unit 140 adds the calculated temperature correction amount and the measured value of the temperature sensor 11 stored in step S134. By this processing, the correction processing of the urine temperature measurement value in consideration of both the environmental temperature and the personal information which are influential factors in the present invention is completed, and the excretion urine temperature in the present invention is obtained.

  When the excretion urine temperature is calculated, the control unit 140 generates a result display signal that is a control signal to be transmitted to the remote control device 5 based on the excretion urine temperature information and the personal identification information. When this process ends, the control unit 140 shifts the process to step S138.

  In step S138, the control unit 140 executes a result display signal transmission process. Specifically, control unit 40 performs processing for transmitting the result display signal generated in step S137 to remote control device 105. When this process ends, the control unit 140 shifts the process to step S139.

  In step S139, the control unit 140 executes a urine container storage cleaning process. When this process ends, the control unit 140 returns the process to step S131, and all the urine temperature measurement operations are ended.

  In the correction processing flow of this embodiment, the correction amounts obtained in steps S135 and S136 are corrected by adding them in step S137. However, the environmental temperature, sex, and age, which are influential factors of this embodiment, are corrected. Therefore, a processing flow may be used in which the correction amount is obtained in one step using the temperature correction table.

  Further, in the urine temperature measuring device 104 according to the present embodiment, gender and age are used as the personal body information of the subject, but other physical information related to the urination state of the subject, for example, body shape such as height and BMI is used. It is conceivable to use a factor appropriately selected from factors including related indicators.
