Description

[Technical Field]

[0001] The present invention relates to a urine volume management system. [Background technology]

[0002] In order to monitor the physical condition of patients with disorders of urine collection and urination functions or to confirm the effectiveness of treatment, daily urination volume is monitored. Conventionally, urine volume was measured by collecting urine in a urine collection cup during urination, but this urine collection procedure is both tedious and unhygienic. In addition, after measuring the urine volume in the urine collection cup, the value had to be recorded on a record sheet.

[0003] In response to this, a urination volume management system has been proposed in which a patient's weight before and after urination is measured using a scale, and the urination volume is calculated from the weight loss (Patent Document 1). This system includes a scale and a urination volume management terminal connected to the scale via a wireless or wired communication line. The urination volume management terminal receives the weight measurements before and after urination transmitted from the scale via the communication line, and calculates the difference between these weight measurements as the urination volume. The calculated urination volume data is stored in a memory unit included in the urination volume management terminal or in a management device connected to the urination volume management terminal via the communication line.

Examination transmitting a trigger signal to a first control unit of the user terminal; When the first control unit receives the trigger signal, the first control unit causes the voice instruction unit to output a voice instruction message having content instructing an operation corresponding to the trigger signal. [Effects of the Invention]

[0008] According to the urination volume management system of the present invention, by listening to the voice instruction message output from the voice instruction unit of the subject terminal while the two weight measurement processes are being carried out, the subject can easily recognize the next action to be taken, thereby improving convenience for the subject.

[Figure 4] An enlarged view of the operation instruction screen in Figure 3(2). DETAILED DESCRIPTION OF THE INVENTION

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.

[0011] [Overall configuration of the urination volume management system] FIG. 1 is a diagram that shows a schematic diagram of a urination volume management system 1 of this embodiment. FIG. 2 is a schematic block diagram of the urination volume management system 1. This urination volume management system 1 includes a measurement device 100 that measures body weight, a user terminal 200 as a subject terminal, and an administrator terminal 300. The urination volume management system 1 is set up in a medical institution such as a hospital, the subject's home, etc. When the urination volume management system 1 is installed in a medical institution, a plurality of user terminals 200 can be used.

[0012] The measuring device 100 corresponds to the urination volume measuring meter of the present invention and has a flat housing 101. The user terminal 200 is configured as, for example, a smartphone or a tablet terminal. The measuring device 100 and the user terminal 200 are each equipped with short-range wireless communication circuits (hereinafter simply referred to as "communication circuits") 180, 280, respectively, and are configured to be able to wirelessly communicate with each other. The administrator terminal 300 is, for example, a desktop, notebook, or tablet personal computer, and is connected to the user terminal 200 by short-range wireless communication. The administrator terminal 300 and the user terminal 200 may be connected via a local network within the facility where the urination volume management system 1 is installed, or via the Internet.

[0013] [Configuration of measurement equipment] The measuring device 100 is equipped with a CPU 170, a communication circuit 180, a power supply control circuit 160, an LED control circuit 165, an A / D conversion circuit 130, a USB / serial conversion circuit 145, memory (ROM (Read Only Memory) and RAM (Random Access Memory)) 171, a power supply battery 140, an LED 175, and a load cell 110, all of which are housed in a housing 101. The A / D conversion circuit 130 and the load cell 110 correspond to a weight measurement unit, and the CPU 170 corresponds to a second control unit.

[0014] The load cell 110 is a type of weight sensor in which distortion caused by the weight of a patient or the like placed on the housing 101 appears as a change in resistance value. The change in resistance value is output from the load cell 110 as a voltage signal or a current signal. The signal output from the load cell 110 is converted into a digital value by the A / D conversion circuit 130 and then input to the CPU 170.

[0015] The USB / serial conversion circuit 145 converts various signals input and output from the USB port 173 into serial data and inputs it to the CPU 170. The ROM stores a program describing the processing procedures of the CPU 170, and the CPU 170 functions as a control unit by expanding the program into RAM or the like and executing it. The ROM also stores various tables (maps) used for various calculations. The CPU 170 executes various processes in the measuring device 100 according to these programs and tables. The various processes are not limited to those executed by software, and can also be executed by dedicated hardware (electronic circuits).

[0016] The power supply control circuit 160 controls the charging and discharging of the built-in power supply battery 140 and monitors the remaining charge. The power supply control circuit 160 converts the fluctuating voltage of the battery 140 into the required constant voltages and supplies them to the CPU 170, memory 171, load cell 110, A / D conversion circuit 130, communication circuit 180, etc. The battery 140 is configured to be rechargeable via a USB port 173.

[0017] Power switch 176 is a switch for turning on / off measurement device 100. Even if measurement device 100 is turned on by power switch 176, it is generally in a sleep state when not measuring weight in order to achieve low power consumption.

[0018] In the sleep state, the communication circuit 180 and some functions of the CPU 170 that controls the communication circuit 180 in the measurement device 100 are running at low power. The communication circuit 180 starts periodically, and when communication is established with one of the user terminals 200, the CPU 170 starts up fully. It is preferable to use a communication circuit 180 that complies with a low-power standard, such as Bluetooth (registered trademark) Low Energy. The CPU 170 externally displays the operating status of the measurement device 100 using an LED 175, which is an RGB indicator.

[0019] In the measuring device 100, after communication with the user terminal 200 is established, the CPU 170 changes from a low-power startup state to a state capable of high-performance calculations, and causes the power supply control circuit 160 to energize other units such as the load cell 110. Then, when measuring body weight, the CPU 170 starts calculating the signal from the load cell 110, which increases power consumption.

[0020] The CPU 170 has high processing power capable of high-speed calculations up to the floating point in order to realize weight measurement. Therefore, if the load cell 110 and the downstream processing circuit are kept in a standby state at all times to detect the load, power consumption will be large. Therefore, in the sleep state, the urination volume management system 1 of this embodiment periodically turns on and off the low-power consumption communication circuit 180 and the CPU 170 that controls it. Then, after the CPU 170 of the measuring device 100 receives a wireless communication request from the user terminal 200, it starts up the entire device, including the load cell 110.

[0021] With the above configuration, the power consumption of the measuring device 100 in sleep mode can be limited to the power consumption of the communication circuit 180 and the CPU 170 in low power mode. In the urination volume management system 1, weight is measured twice each time the patient urinates, once before and after urination, so the power consumption of the measuring device 100 increases dramatically compared to when weight is measured once a day, for example. In contrast, the measuring device 100 of this embodiment reduces power consumption in sleep mode, and therefore the life of the battery 40 can be dramatically extended.

[0022] [User device configuration] User terminal 200 is configured, for example, as a smartphone or tablet terminal, and is configured separately from measuring device 100. User terminal 200 includes CPU 270, memory 271, input operation unit 274 consisting of a touch panel or buttons for accepting input operations, display unit 210 for displaying a screen, audio instruction unit 276, and short-range wireless communication circuit 280. CPU 270 functions as a first control unit and arithmetic unit of the present invention. There may be multiple user terminals 200 (for example, 1 to N; N is a natural number). When there are multiple user terminals, identification information for distinguishing each terminal from the other terminals is stored in advance in memory 271.

[0023] A control program (system software) is stored in the memory 271, and the CPU 270 executes this program to function as a control unit of the user terminal 200. The memory 271 also stores application software dedicated to the urination volume management system 1, and the CPU 270 executes this software to send a wireless communication request, and communication between the measuring device 100 and the user terminal 200 is performed only when the measuring device 100 receives this request. In other words, the measuring device 100 does not respond to wireless communication requests sent from general smartphones or tablet devices. This configuration prevents personal information of the user, who is the owner of the user terminal 200, from being leaked to third parties, and is transmitted and received between the measuring device 100 and the user terminal 200.

[0024] [Urine volume measurement processing] Next, we will explain the urine volume measurement process executed using the measurement device 100 and the user terminal 200. Fig. 3 shows an example of a screen displayed on the display unit of the user terminal 200 when the urine volume measurement process is being executed.

[0025] When the urine volume measurement process is executed, it is assumed that the power switch 176 has been used to turn on the measuring device 100. When the power is turned on, the CPU 170 activates the communication circuit 180 and determines whether communication has been established. If it determines that communication has not been established, the CPU 170 goes into a sleep state for a certain period of time. After the certain period of time has elapsed, the CPU 170 activates the communication circuit 180 again and determines whether communication has been established. In the sleep state, the measuring device 100 periodically repeats the process of activating the communication circuit 180 and determining whether communication has been established.

[0026] On the other hand, when the user starts up the user terminal 200, the CPU 270 executes the dedicated application software. As a result, an initial screen for measuring weight before urination is displayed on the screen of the display unit 210 (FIG. 3(1)). This initial screen displays the name and identification number of the user (subject) who owns the user terminal 200, as well as a GUI (Graphical User Interface) button 211 for confirming the intention to start the urine volume measurement process. This GUI button 211 consists of a rectangular frame with the word "Start" displayed within it.

[0027] When CPU 270 detects that the user has touched GUI button 211, CPU 270 activates communication circuit 280 to send a wireless communication request and determines whether communication can be established with measuring device 100. If measuring device 100 is not nearby, or if the main power of measuring device 100 is turned off, communication will not be established. If a preset timeout period has elapsed without communication being established, CPU 270 switches user terminal 200 to the OFF state.

[0028] If it is determined that communication with the measurement device 100 has been established, the CPU 270 transmits a command C1 to the measurement device 100. Upon receiving the command "C1", the CPU 170 of the measurement device 100 returns a command A1 to the user terminal 200. 2Upon receiving the command A1, the device 70 displays on the display unit 210 a screen (operation instruction screen) for instructing the user on the next operation to be performed (FIG. 3(2)).

[0029] In the following description, commands transmitted from the measurement device 100 to the user terminal 200 are distinguished by being marked with a symbol consisting of a combination of "A" and a number, and commands transmitted from the user terminal 200 to the measurement device 100 are distinguished by being marked with a symbol consisting of a combination of "C" and a number. Command A transmitted from the measurement device 100 to the user terminal 200 corresponds to a trigger signal.

[0030] Figure 4 is an enlarged view of the operation instruction screen in Figure 3(2). This operation instruction screen displays a text message 221 ("Please get on the measuring device") instructing the user to get on the housing 101 of the measuring device 100 to measure body weight, and an image 222 showing a person getting on the measuring device 100. The operation instruction screen also displays a bar (progress bar) 223 indicating the progress of the urination volume measurement process, and a supplementary explanation 224 regarding the status of the measuring device 100. The image 222 may be a still image or a video.

[0031] Simultaneously with the screen display on the display unit 210, the CPU 270 causes the voice instruction unit 276 to output a voice message ("Please get on the measuring device") instructing the user to perform an action.

[0032] Therefore, the user can determine the next action to be taken by looking at the text message 221 and image 222 displayed on the screen of the display unit 210, or by listening to the voice message. In this way, the next action to be taken is instructed by both visual information, i.e., the text message 221 and image 222, and auditory information, i.e., the voice message, making the system easy to use even for users with impaired eyesight, hearing, or both, or for those with cognitive problems. In addition, by expressing the content of the action instruction using image 222, the system is easy to use even for young children and foreign patients who cannot understand the content of text or voice instructions.

[0033] Furthermore, the user can visually grasp the progress of the urination measurement process from the progress bar 223 displayed on the operation instruction screen. Furthermore, the user can proceed with the urination volume measurement process by associating it with the state of the measurement device 100 from the supplementary explanation 224.

[0034] If a predetermined time has elapsed since user terminal 200 transmitted command "C1" and command "A1" has not been transmitted from measurement device 100, CPU 270 transmits command "C1" again. If command "A1" has not been transmitted from measurement device 100 even after the process of transmitting command "C1" has been repeated multiple times (for example, 10 times), an error screen is displayed on display unit 210.

[0035] On the other hand, when communication with user terminal 200 is established, CPU 170 of measuring device 100 transitions circuits required for measurement, such as load cell 110, from a sleep state to a measurable state. Thereafter, CPU 170 observes changes in the resistance value of load cell 110 for a certain period of time using the digital value obtained from A / D conversion circuit 130.

[0036] When a user stands on housing 101 of measuring device 100, a digital value representing a change in the resistance value of load cell 110 is input from A / D conversion circuit 130 to CPU 170. CPU 170 detects from this digital value that the user is standing on housing 101, and transmits command A2 to user terminal 200. Upon receiving command A2 from measuring device 100, CPU 270 of user terminal 200 switches the screen of display unit 210 to a screen indicating that weight measurement is in progress (FIG. 3(3)), and causes audio message output from audio instruction unit 276. On this screen, a text message explaining precautions to take during measurement, "Measurement in progress, please do not move on the measuring device," is displayed, and an image of a person standing upright on measuring device 100 is also displayed. An audio message with the same content as this text message is also output from audio instruction unit 276.

[0037] Furthermore, CPU 170 calculates the measured weight of the user while performing averaging of the digital values ​​input from load cell 110. This makes it possible to stably measure the weight even if the user moves on housing 101 and the change in the resistance value of load cell 110 is unstable.

[0038] When the calculation of the user's weight measurement value is completed, CPU 170 transmits command A3 to user terminal 200. Upon receiving command A3, CPU 270 of user terminal 200 switches the screen of display unit 210 to a screen (FIG. 3(4)) indicating that measurement has ended, and outputs a voice message from voice instruction unit 276. This screen displays a text message explaining what to do after measurement has ended: "Measurement completed. Please step down from the measuring device," and displays an image of a person stepping down from measuring device 100. Furthermore, voice instruction unit 276 outputs a voice message with the same content as this text message.

[0039] When the user gets off the measuring device 100, the digital value input from the A / D conversion circuit 130 drops suddenly. The CPU 170 detects from the change in the digital value that the user has gotten off the measuring device 100 and sends command A4 to the user terminal 200. The CPU 170 also obtains the user's weight by subtracting the weight measurement value calculated from the digital value at that time from the weight measurement value when the user was standing on the measuring device 100. The obtained weight value is stored in memory 171 as the weight value before urination.

[0040] Furthermore, upon receiving command A4 from the measuring device 100, the CPU 270 of the user terminal 200 transmits command C2 to the measuring device 100. Upon receiving command C2, the CPU 170 of the measuring device 100 reads the pre-urination weight value from memory 171 and transmits it to the user terminal 200. Upon receiving the pre-urination weight value, the CPU 270 of the user terminal 200 stores the value in memory 271. Furthermore, the CPU 270 switches the screen of the display unit 210 to an action instruction screen (FIG. 3(5)) for instructing the user on the next action to be taken, and outputs a voice message from the voice instruction unit 276. At the same time, the user terminal 200 transmits command C3 to the measuring device 100.

[0041] This action instruction screen displays a text message saying "Measure again after urinating in the toilet," along with images showing the action of urination in the toilet and the action of getting on the measuring device 100. In addition, a voice message with the same content as this text message is output from the voice instruction unit 276.

[0042] Upon receiving command C3 from user terminal 200, CPU 170 of measurement device 100 transmits command A5 to user terminal 200. Upon receiving command A5, CPU 270 of user terminal 200 disconnects communication with measurement device 100 and puts user terminal 200 into a sleep state.

[0043] When a predetermined time has elapsed since the user terminal 200 went into sleep mode, the CPU 270 displays an initial screen for measuring weight after urination on the screen of the display unit 210 (FIG. 3(6)). This initial screen displays a GUI button 212 for confirming the intention to start the weight measurement process after urination. This GUI button 21 2 The symbol consists of a rectangular frame with the words "Proceed to measurement after urination" written inside it.

[0044] When CPU 270 detects that the user has touched GUI button 212, CPU 270 activates communication circuit 280 to send a wireless communication request and determines whether communication can be established with measuring device 100. If measuring device 100 is not nearby or if the main power of measuring device 100 is turned off, communication will not be established. If the state in which communication is not established continues for a preset timeout period, CPU 270 returns user terminal 200 to a sleep state.

[0045] Furthermore, if the GUI button 212 is not touched even after a predetermined time has elapsed since the initial screen for measuring weight after urination was displayed on the display unit 210, the CPU 270 also returns the user terminal 200 to the sleep state. When a predetermined time has elapsed after the user terminal 200 returned to the sleep state, the CPU 270 causes the screen of the display unit 210 to display the initial screen for measuring weight after urination again.

[0046] After displaying the initial screen for measuring weight after urination on the display unit 210, the user terminal 200 is returned to a sleep state, and the process of displaying the initial screen on the display unit 210 again is repeated multiple times (for example, 10 times) (snooze function). If communication is not established between the user terminal 200 and the measuring device 100 even after the above process has been repeated multiple times, or if the GUI button 212 is not touched, the CPU 270 discards the weight value data stored in the memory 271 and ends the urination volume measurement process.

[0047] On the other hand, when the GUI button 212 is touched and it is determined that communication between the user terminal 200 and the measuring device 100 has been established, the CPU 270 sends a command C1 to the measuring device 100. From this point onwards, the operations of the measuring device 100 and the user terminal 200 carried out until the user's weight measurement is completed, the screens (FIGS. 3(7) to (9)) displayed on the display unit 210 of the user terminal 200, and the voice messages output from the voice instruction unit 276 are the same as those when measuring weight before urination, and therefore will not be described here.

[0048] When the CPU 170 of the measuring device 100 obtains the user's weight value after urination, it transmits this weight value to the user terminal 200. Upon receiving the post-urination weight value, the CPU 270 of the user terminal 200 reads the pre-urination weight value stored in memory 271 and calculates the amount of urine. The amount of urine is obtained by subtracting the post-urination weight value from the pre-urination weight value. If necessary, the weight value may be converted to volume using the standard density of urine. The amount of urine obtained by the calculation is displayed on the screen of the display unit 210 (Figure 3(10)) and is also stored in memory 271. This screen displays the amount of urine as well as a GUI button 213 that prompts the user to move to the next screen. This button 213 consists of a rectangular frame with the word "Next" displayed within it.

[0049] When the GUI button 213 is touched, the CPU 270 displays a screen (additional information selection screen) on the display unit 210 for the user to input additional information. For example, FIG. 3(11) is a screen for selecting whether or not the additional information is urination while asleep, and FIG. 3(12) is a screen for selecting whether or not there is an urge to urinate, whether or not there is urine leakage, and whether or not there is feces, as additional information. These additional information selection screens display GUI buttons as selection buttons. In addition to these, the additional information may also include an evaluation of the amount of urine voided, whether or not there is blood in the urine, whether or not there is pain during urination, etc.

[0050] When input of additional information by touching the GUI button on the additional information selection screen is completed, the CPU 270 stores the calculated urination volume and additional information together with the date and time in the memory 271. The CPU 270 also transmits the data such as the urination volume and additional information stored in the memory 271 to the administrator terminal 300. Fig. 3 (13) shows a standby screen indicating that data is being transmitted from the user terminal 200 to the administrator terminal 300, and Fig. 3 (14) shows an end screen indicating that data transmission has ended and all urination volume measurement processing has been completed.

[0051] (Variation) The present invention is not limited to the above-described embodiment and can be modified as appropriate. For example, in the above embodiment, an operation instruction screen is displayed on the display unit 210 of the user terminal and at the same time a voice instruction message is output from the voice instruction unit 276, but it is also possible to output only the voice instruction message from the voice instruction unit 276 without displaying the operation instruction screen on the display unit 210.

[0052] Furthermore, in the urine volume measurement process, whenever an operation instruction screen is displayed on the display unit 210, a voice message is output from the voice instruction unit 276. However, it is also possible to output a voice message from the voice instruction unit 276 when a part of the operation instruction screen is displayed on the display unit 210.

[0053] Furthermore, the above-described embodiment and the various modifications described above are merely examples of the present invention, and it is natural that any appropriate modifications, alterations, additions, etc. made within the spirit of the present invention will also be encompassed within the scope of the claims of the present application.

[0054] It will be appreciated by those skilled in the art that the exemplary embodiments described above are examples of the following aspects.

[0055] (Section 1) The urination volume management system in paragraph 1 is a subject terminal having a voice instruction unit and a first control unit that controls the voice instruction unit; a urination volume measuring meter configured to be capable of wireless communication with the subject terminal, the urination volume measuring meter having a weight measurement unit and a second control unit that causes the weight measurement unit to execute a weight measurement process; a calculation device for calculating the amount of urine voided from the weight measurements obtained in each of the two weight measurement steps; In a urine volume measurement system comprising: The urination volume measuring device measures the amount of urine of the subject when each measurement step included in the two weight measurement steps is completed. Examination transmitting a trigger signal to a first control unit of the user terminal; When the first control unit receives the trigger signal, the first control unit causes the voice instruction unit to output a voice instruction message having content instructing an operation corresponding to the trigger signal.

[0056] In the urination volume management system of paragraph 1, the two weight measurement steps are steps in which the subject steps on the urination volume meter to measure the subject's weight before and after urination. Also, "actions corresponding to a trigger signal" include, for example, the subject steps on the urination volume meter, steps off the urination volume meter, or steps to go to the toilet to urinate after the first weight measurement step.

[0057] According to the urination volume management system of paragraph 1, the subject can easily know the next action to be taken by listening to the voice instruction message output from the voice instruction unit of the subject terminal while the weight measurement process is being performed using the urination volume measuring meter.

[0058] (Section 2) In the urination volume management system of paragraph 1, The subject terminal further has a display unit, The first control unit may cause the display unit to display an instruction screen corresponding to the voice instruction message in conjunction with the voice instruction unit.

[0059] (Section 3) In the urination volume management system of paragraph 2, The instruction screen may be a character string and / or an image indicating the content of the voice instruction message.

[0060] According to the urination volume management system of the second and third aspects, the subject can be instructed to perform an action using both auditory information in the form of a voice instruction message and visual information in the form of an instruction screen displayed on the display unit.

[0061] (Section 4) In any one of the urine volume management systems of paragraphs 1 to 3, the first control unit may cause the voice instruction unit to output the voice instruction message when a predetermined time has elapsed since receiving the signal from the urine volume measuring meter.

[0062] According to the urination volume management system of paragraph 4, even if the subject is located far away from the urination volume measuring meter and the subject terminal is unable to receive signals from the urination volume measuring meter, it is possible to output a voice instruction message from the voice instruction unit of the subject terminal.

[0063] (Section 5) In any of the urine volume management systems of paragraphs 1 to 4, the first control unit may be configured to cause the audio instruction unit to output an audio instruction message prompting the execution of a second weight measurement process when a predetermined time has elapsed since receiving a signal transmitted from the urine volume measuring meter when the first weight measurement process is completed.

[0064] For example, if a subject goes to the toilet after completing the first weight measurement (before urination), but forgets to measure weight after urination and moves away from the urination volume measuring device, the subject terminal will not be able to receive signals from the urination volume measuring device. Even in such a case, the urination volume management system of paragraph 5 can output a voice instruction message from the voice instruction unit of the subject terminal to remind the subject to measure weight for the second time (after urination).

[0065] (Section 6) In any one of the urination volume management systems of paragraphs 1 to 5, the weight measurement unit is configured to be able to transition between a sleep state and a measurement state in which power consumption is higher than that of the sleep state, When the second control unit receives a startup request signal from the subject terminal, it transitions the weight measurement unit from the sleep state to the measurable state, and after the weight measurement unit has completed transitioning to the measurable state, the trigger signal can be transmitted from the urination volume measuring meter to the subject terminal.

[0066] According to the urine volume management system of paragraph 6, the weight measurement unit is in a sleep state until the weight measurement process is performed in the weight measurement unit, so that the power consumption of the urine volume measuring device can be reduced.
