[Technical field]

[0001] The present invention relates to a wristwatch with a heat stroke onset detection function and a heat stroke onset detection program. [Background technology]

[0002] Conventionally, so-called smart watches, which are equipped with a function to automatically measure and display the vital signs of the wearer, have become widespread. In general, smart watches are worn on the wrist and have a temperature sensor and electrodes embedded in the back cover that are in contact with the wrist, and they measure and record the wearer's skin temperature and pulse through the skin of the wrist, as well as the movement speed, movement distance, movement route, etc. that reflect the movement of the arm from the built-in acceleration sensor and GPS sensor. In addition to measuring the time, these sensors also calculate and display body temperature, heart rate, walking steps, exercise time, movement route, movement distance, exercise amount, and even oxygen concentration measurements, etc. on the display.

[0003] In such a smart watch, when a user wears it on their wrist, the sensor detects it and starts various functions, senses various vital sign data, and displays the specified vital sign data on the display panel according to the user's operation. Note that the display format of the vital sign data on the display panel is diverse.

[0007] [Patent Document 1] Patent Publication No. 2022-140935 [Patent Document 2] JP 2023-115827 A Summary of the Invention [Problem to be solved by the invention]

[0008] When you have heatstroke, your body temperature rises. To check if your body temperature has risen, you need to measure it with a thermometer. To measure your body temperature with a thermometer, you need to measure it manually yourself.

[0009] The present invention has been made in consideration of such conventional technology, and aims to provide a wristwatch with a heatstroke onset detection function and a heatstroke onset detection program which incorporates a body surface temperature sensor into a digital wristwatch such as a smartwatch, continuously measures the body surface temperature of the wearer, calculates an estimated body temperature using an original heatstroke onset detection program, and notifies the wearer of the onset of heatstroke by warning the wearer that "heatstroke has occurred" when the calculated estimated body temperature reaches a first standard value, for example 37.8°C or higher, and by warning the wearer that heatstroke is imminent when the calculated estimated body temperature reaches either the first standard value or a lower second standard value, for example 37.3°C to 37.8°C, warning the wearer that heatstroke is imminent, and also warns the wearer of the onset of heatstroke when the onset is imminent. [Means for solving the problem]

[0010] One feature of the present invention is a portable device with a heatstroke onset determination function, comprising: a body surface temperature sensor incorporated into the back cover surface of a wristwatch-type portable device case; multi-colored LEDs installed on the display surface of the case; a liquid crystal display unit provided on the display surface of the case; a sound output unit incorporated into the case; and a vibration unit incorporated into the case, and is equipped with a heatstroke onset determination program execution unit that is built into the case, inputs the measurement signal from the body surface temperature sensor, converts the input body surface temperature into an estimated body temperature, compares the estimated body temperature with a predetermined comparison value, determines the onset of heatstroke when the predetermined comparison value is exceeded, causes the multi-colored LEDs to emit light in a predetermined pattern when the onset of heatstroke is determined, causes the sound output unit to output an onset alarm sound, and vibrates the vibration unit to notify the onset of heatstroke.

[0011] In the above-mentioned portable device with heatstroke onset determination function, the heatstroke determination program execution unit compares a first reference value and a second reference value lower than the first reference value with the converted expected body temperature, and if the expected body temperature is higher than the first reference value, determines that heatstroke has occurred and outputs an onset determination, and if the expected body temperature is lower than the first reference value and higher than the second reference value, outputs an onset warning determination that heatstroke is imminent, changes the state of the light emission pattern of the multi-colored LEDs depending on the onset determination output and the onset warning determination output, and causes the sound output unit to output an onset alarm sound and an onset warning sound separately.

[0012] In the portable device with the heat stroke onset determination function, the vibration unit can be caused to output vibration patterns in a differentiated manner in response to the onset determination output and the onset caution determination output.

[0013] In addition, in the above-mentioned portable device with heatstroke onset determination function, the first reference value is 37.8°C and the second reference value is 37.4°C, and if the expected body temperature is 37.9°C or higher, which is higher than the first reference value, it is determined that heatstroke has occurred and an onset determination is output, and if the expected body temperature is equal to or lower than the first reference value of 37.8°C and equal to or higher than the second reference value of 37.4°C, an onset warning determination is output that the onset of heatstroke is imminent.

[0014] Another feature of the present invention is a heatstroke onset determination program that inputs a body surface temperature measurement signal measured by a body surface temperature sensor built into the back cover surface of the case of a portable device, converts the body surface temperature measurement signal of the body surface temperature sensor into body temperature to calculate an estimated body temperature, compares the estimated body temperature with a predetermined standard value, and determines the onset of heatstroke when the estimated body temperature exceeds the predetermined standard value, and when the onset of heatstroke is determined, causes multiple colored LEDs built into the case to light up in a predetermined pattern, causes a sound output unit built into the case to output an onset alarm sound, and vibrates a vibration unit built into the case to notify the onset of heatstroke.

[0015] In the above-mentioned heatstroke onset determination program, the expected body temperature is compared with a first reference value and a second reference value lower than the first reference value, and if the expected body temperature is higher than the first reference value, a heatstroke onset is determined and an onset determination is output, and if the expected body temperature is lower than the first reference value and higher than the second reference value, an onset warning determination is output indicating that heatstroke is imminent, the light emission pattern of the multi-colored LEDs is changed and output depending on the onset determination output and the onset warning determination output, and the sound output unit is caused to output an onset alarm sound and an onset warning sound separately.

[0016] In addition, the heat stroke onset determination program can cause the vibration unit to output distinct vibration patterns when the heat stroke onset determination is output and when the heat stroke onset warning determination is output.

[0017] Furthermore, in the above-mentioned heatstroke onset determination program, the first reference value is 37.8°C and the second reference value is 37.4°C, and if the expected body temperature is 37.9°C or higher, which is higher than the first reference value, it is determined that heatstroke has occurred and an onset determination is output, and if the expected body temperature is below the first reference value of 37.8°C and above the second reference value of 37.4°C, an onset warning determination is output that heatstroke is imminent. Effect of the Invention

[0018] According to the present invention, the body surface temperature of the wearer is continuously measured, the internal body temperature is calculated from the measured body surface temperature using a predetermined arithmetic formula, the calculated body temperature is used as the assumed body temperature, and if the assumed body temperature is continuously above a predetermined standard value, it is determined that heat stroke has occurred and an onset alarm is issued to notify the wearer and people around them and alert them.

[0019] Furthermore, according to the present invention, a first reference value and a lower second reference value are set as reference values, and when the first reference value, for example 37.9°C, is reached or exceeded, a warning of "onset of heatstroke" is issued, and when the calculated assumed body temperature is between the first reference value and a lower second reference value, for example 37.4°C to 37.8°C, a warning of impending onset of heatstroke is issued, thereby making it possible to warn of the onset of heatstroke and to warn of imminent onset.

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0022] 1 to 3 show a wristwatch-type portable device 1 with a heat stroke onset determination function according to an embodiment. The front side of the portable device 1 is equipped with a display panel 2. It is also possible to incorporate a digital clock so that the time according to the digital clock can be displayed digitally. A body surface temperature sensor 4 is built into the back cover 3 of the portable device 1, which comes into contact with the skin on the wrist of the wearer to measure and output the body surface temperature.

[0023] When the user wears the portable device 1 on his / her arm and presses the clock display button 5, for example, the digital time is displayed on the liquid crystal display panel 2. When the user presses the heat stroke onset determination operation button 6 to start measuring body temperature, the body surface temperature sensor 4 is activated to measure the body surface temperature of the wearer's wrist, and the built-in heat stroke onset determination program calculates the estimated body temperature from the measured body surface temperature, and determines whether the calculated estimated body temperature is high or low, i.e., whether heat stroke has occurred and there is a risk, whether extreme caution is required as the onset is imminent, or whether there is no need to worry. The result of the determination is notified by the lighting patterns of the three colors, blue, red, and yellow, LEDs 10B, 10R, and 10Y, installed on the display panel 2 of the portable device 1. The result is also notified by the vibration pattern of the built-in vibration unit and the sound output pattern of the sound output unit.

[0024] 4, the portable device 1 with heat stroke onset determination function of this embodiment includes a body surface temperature sensor 11 as an input, a liquid crystal display unit 13 that displays characters as an output, a multi-color LED 10, a vibration unit 15 that can change the vibration pattern, a sound output unit 16 that can change the sound output pattern and the intermittent length and pitch of the sound, and an internal heat stroke onset determination program execution unit 12. This heat stroke onset determination program execution unit 12 executes the built-in heat stroke onset determination program.

[0025] The heat stroke onset determination program execution unit 12 executes this heat stroke onset determination program by receiving input from a start / stop button 6 for the heat stroke determination function installed on the case of the portable device 1, input of a voltage signal for estimating the remaining capacity from the built-in battery 7, and input from the body surface temperature sensor 11. If the portable device 1 has a clock function such as a so-called smart watch, the program execution unit 12 can use those normally installed functional units.

[0026] The heat stroke onset determination program execution unit 12 includes a body temperature calculation unit 21 that calculates the body surface temperature measurement value input from the body surface temperature sensor 11 using a predetermined program to calculate the body temperature (estimated body temperature), a heat stroke determination unit 22 that compares a first reference value R1 with a second reference value R2 lower than the first reference value and the estimated body temperature T, determines that heat stroke has occurred and outputs an onset determination if the estimated body temperature T is higher than the first reference value R1, and outputs an onset warning determination that heat stroke is imminent if the estimated body temperature is lower than the first reference value R1 and higher than the second reference value R2. The heat stroke determination unit 22 further includes a third reference value R3 set for determining that the body temperature measurement has failed if the estimated body temperature T is lower than this value.

[0027] Furthermore, the heatstroke onset determination program execution unit 12 has an LED output control unit 23 that changes the light emission pattern of the multi-colored LEDs 10 depending on the onset determination output and caution determination output output by the heatstroke onset determination unit 22, a vibration control unit 24 that changes the vibration pattern and vibrates the vibration unit 15, and a sound output control unit 25 that causes the sound output unit 16 to output an onset notification sound and an onset caution warning sound separately.

[0028] The portable device 1 has a program execution start / stop operation button 6, and a battery 7 is built into the device case.

[0029] The body temperature measurement and heat stroke onset warning functions by the heat stroke onset determination program execution unit 12 will be described with reference to the flowcharts of FIG. 5A and FIG. 5B. In order to start the body temperature measurement program registered inside the portable device 1, the execution start / stop operation button 6 is pressed and held for, for example, 5 seconds (step ST1). This turns on the power for program execution, the battery capacity lamp 10 lights up, and the timer starts. If the remaining battery level is 10% or more, body temperature measurement is possible, so the process proceeds to YES (steps ST2, ST4). If the remaining battery level is less than 10%, it is determined that body temperature measurement is not possible, so the process branches to NO, flashes the LED 10 three times, emits one set of abnormality notification sounds "beep, beep, beep," and simultaneously vibrates the watch 1 to inform the user that the remaining battery level is low (step ST3). In this case, body surface temperature measurement is still possible, so the process proceeds to step ST4.

[0030] In step ST4, it is determined whether the power button 5 has been clicked twice in succession. If it has been clicked twice in succession, the process branches to YES and proceeds to step ST5. If it has not been clicked twice in succession, the process branches to NO and proceeds to step ST6. In step ST6, it is determined whether the timer has counted down for 30 minutes. If 30 minutes have not yet counted up, the process branches to NO and returns to step ST2. If 30 minutes have counted up in step ST6, the process branches to YES and the timer is reset (step ST7), returning the timer to the start state and proceeding to step ST5.

[0031] In step ST5, the three color LEDs 10 are caused to flash in sequence to indicate that temperature measurement is in progress, and the body surface temperature is measured (step ST8). During temperature measurement, the three color LEDs 10 continue to flash in sequence.

[0032] Once the body surface temperature measurement is completed, the built-in body temperature calculation program calculates the assumed body temperature T from the input measured body surface temperature (step ST9).

[0033] In the subsequent judgment process from step ST10 onwards, it is judged whether or not heat stroke has occurred depending on how high the calculated assumed body temperature T is. In step ST10, if the assumed temperature is higher than 34°C, the measured temperature is considered valid, branching to YES, and proceeding to the next step ST11.

[0034] In step ST11, it is determined whether the body temperature is normal or high depending on whether the calculated expected temperature T is higher or lower than 37.3°C. If it is determined to be high body temperature, it is further determined whether the calculated expected temperature T is higher or lower than 37.8°C (step ST12). If the body temperature is higher than 37.8°C, it is determined to be heat stroke, and to notify the onset of heat stroke, the red LED lamp 10R is flashed to warn, an abnormal beeping sound is emitted, and the device case is vibrated (step ST17). This notification of the onset of heat stroke continues until the operation start / stop operation button 6 is pressed and it is determined that the user has acknowledged it (step ST18).

[0035] If the expected temperature is 34° C. or lower in step ST10, the measured temperature is considered invalid and the process branches to NO, causing the three-color LEDs 10R, 10Y, and 10B (blue, yellow, and red) to flash three times simultaneously, outputting a set of abnormal sounds (beep, beep, beep), and vibrating the device case (step ST13), resetting the counter for the number of times the warning message has been displayed, and returning to the process from step ST2 (step ST10).

[0036] If the temperature comparison in step ST11 finds that the expected temperature is 37.3°C or lower, the process branches to NO, the body temperature is considered normal, the blue LED 10B flashes three times, the counter for the number of times the warning has been displayed is reset, and the process returns to step ST2 (steps ST15 and ST16).

[0037] If the expected temperature calculated by the temperature comparison in step ST11 is 37.4°C or higher and is not considered to be normal body temperature, but if the expected temperature is 37.8°C or lower, it is necessary to alert the user that the body is overheating and that there is a risk of developing heatstroke. Therefore, in step S12, the process branches to NO to display a warning of the onset ...

[0038] In this way, according to the heat stroke onset determination program of this embodiment, the body surface temperature of a person is continuously measured by a sensor, and the internal body temperature is calculated from the measured temperature. If the calculated estimated body temperature exceeds 37.3°C, the user is alerted by a warning sound, vibration, and special pattern LED lighting to alert the user to the onset of heat stroke if the temperature occurs repeatedly. If the calculated estimated body temperature exceeds 37.8°C and is 37.9°C or higher, the onset of heat stroke is immediately displayed, and the user is notified by a warning sound, vibration, and special pattern LED lighting to evoke a sense of urgency. This allows the user to be notified of a reliable warning of the onset of heat stroke and a warning of onset.

[0039] In this embodiment, the body surface temperature sensor 4 may be incorporated in a wristwatch-type so-called smartwatch, and body temperature data may be sent to a smartphone via Bluetooth communication, and an application installed on the smartphone may determine and output the heatstroke onset state and onset alert state. Furthermore, a heatstroke onset determination program may be incorporated into both the smartphone and the smartwatch. [Explanation of symbols]
