DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are subject to various limitations that are technically preferable for implementing the present invention. Therefore, the technical scope of the present invention is not limited to the following embodiments and illustrated examples.

[0010] <First embodiment> First, a first embodiment of the present invention will be described.

[0011] [Configuration of temperature measurement system 100] FIG. 1 is a diagram showing an example of the overall configuration of a temperature measurement system 100 according to the present invention. 1, the temperature measurement system 100 includes an ear thermometer 1 (temperature measurement device) and a terminal device 2 (information processing device). The ear thermometer 1 and the terminal device 2 can transmit and receive data via wireless communication or wired communication.

[0012] 2, the ear thermometer 1 is attached to the ear of a user US and measures the ear temperature as the deep body temperature of the user US continuously for a long period of time. The terminal device 2 is carried by the user US and determines whether the attachment position of the ear thermometer 1 has shifted based on the ear temperature data D1 and the outside air temperature data D2 acquired from the ear thermometer 1.

[0013] [Ear thermometer 1 configuration] Fig. 3 is a diagram showing the external configuration of the ear thermometer 1. Fig. 4 is a block diagram showing the functional configuration of the ear thermometer 1. As shown in FIG. 3, the ear thermometer 1 includes a housing 10a that engages with the entrance of the ear canal, and an ear insertion part 10b that is attached to the side wall surface of the housing 10a and is inserted into the ear canal and fixed therein.

[0014] The tip of the ear insertion part 10b is provided with a first measuring part 11 (first sensor) shown in FIG. 4. The first measuring part 11 is a sensor that includes an infrared temperature element and measures a first temperature including the temperature inside the ear of the user US. In addition, a second measuring part 12 (second sensor) is provided on the side closer to the housing 10a of the ear insertion part 10b. The second measuring part 12 is disposed on the side closer to the outside of the ear than the first measuring part 11 inserted inside the ear (ear canal) or outside the ear. The second measuring part 12 is a sensor such as a thermistor that measures a second temperature including the temperature around the user US (outside air temperature). The data of the first temperature measured by the first measuring part 11 and the data of the second temperature measured by the second measuring part 12 (referred to as inside-ear temperature data D1 and outside air temperature data D2, respectively) are output to the control part 13.

[0015] The housing 10a includes a control unit 13, a storage unit 14, and a communication unit 15. The control unit 13 is a computer that controls each part of the ear thermometer 1. Specifically, the control unit 13 is configured with at least one CPU (Central Processing Unit), RAM (Random Access Memory), etc., reads out a specified program from among the programs stored in the storage unit 14, expands it in the RAM, and executes various processes in cooperation with the expanded program. In this embodiment, when the control unit 13 receives a measurement start instruction from the terminal device 2 via the communication unit 15, it causes the first measuring unit 11 and the second measuring unit 12 to start measurement, and associates the ear temperature data D1 output from the first measuring unit 11 and the outside air temperature data D2 output from the second measuring unit 12 with time information and transmits them to the terminal device 2 via the communication unit 15.

[0016] The storage unit 14 is configured with a non-volatile semiconductor memory, etc. The storage unit 14 stores various programs and data required for executing the programs.

[0017] The communication unit 15 performs communication control for transmitting and receiving data to and from an external device such as the terminal device 2 through wireless or wired communication.

[0018] [Configuration of terminal device 2] The terminal device 2 is, for example, a smart watch, a smartphone, or the like. FIG. 5 is a block diagram showing the functional configuration of the terminal device 2. As shown in FIG. As shown in FIG. 5, the terminal device 2 includes a control unit 21, an operation unit 22, a storage unit 23, a display unit 24, a communication unit 25, an audio output unit 26, and the like.

[0019] The control unit 21 is a computer that controls each part of the terminal device 2. Specifically, the control unit 21 is configured with at least one CPU (Central Processing Unit), RAM (Random Access Memory), etc., reads out a specified program from among programs stored in the storage unit 23, expands the program in the RAM, and executes various processes including a position deviation determination process A described later in cooperation with the expanded program.

[0020] The operation unit 22 is composed of push button switches, a touch panel attached to the display unit 24, and the like. The operation unit 22 outputs an operation signal of the push button switch by the user US and an operation signal on the screen of the display unit 24 to the control unit 21.

[0021] The storage unit 23 is configured with a non-volatile semiconductor memory, a HDD (Hard Disk Drive), etc. The storage unit 23 stores various programs and data required for executing the programs. The storage unit 23 is not limited to being built into the terminal device 2, and may include an external recording medium that is detachable from the terminal device 2.

[0022] For example, the memory unit 23 stores an ear temperature measurement program 231. The ear temperature measurement program 231 is an application program for acquiring and recording ear temperature data D1 from the ear thermometer 1 and determining whether the ear thermometer 1 is in a misaligned position. The ear temperature measurement program 231 includes a program for executing a misalignment determination process A, which will be described later. Furthermore, the memory unit 23 stores the ear temperature data D1 and the outside air temperature data D2 acquired from the ear thermometer 1.

[0023] The display unit 24 is configured with a display device such as a liquid crystal display, an organic EL (Electro Luminescence) display, or the like, and performs display based on the control operation of the control unit 21.

[0024] The communication unit 25 performs communication control for transmitting and receiving data to and from external devices such as the ear thermometer 1 via wireless communication.

[0025] The audio output unit 26 is configured with a speaker or the like, and generates voice or beep sounds to notify the user.

[0026] [Operation of temperature measurement system 100] Next, the operation of the temperature measurement system 100 in the first embodiment will be described. In addition to the influence of changes in outside air temperature, factors that can cause temperature measurement errors in the ear thermometer 1 that is compatible with long-term measurement include deviations in the position at which the ear thermometer 1 is attached. The temperature inside the ear has a temperature gradient in which the temperature gradually decreases from the eardrum side to the outside of the ear. Therefore, if the position at which the ear thermometer 1 is attached shifts and the location at which the temperature is measured by the first measuring unit 11 changes, the measured temperature may change even though the temperature inside the ear does not change.

[0027] 6 is a graph showing the changes in the ear temperature data D1 acquired from the first measuring unit 11 and the outside air temperature data D2 acquired from the second measuring unit 12 when the wearing position of the ear thermometer 1 is temporarily shifted. As shown by the dashed-dotted rectangle in FIG. 6, the ear temperature data D1 changes when the wearing position of the ear thermometer 1 is shifted, but the outside air temperature data D2 does not change.

[0028] Therefore, in the temperature measurement system 100 of the first embodiment, the magnitude of change in the ear temperature data D1 and the outside air temperature data D2 is used to determine whether or not the wearing position of the ear thermometer 1 has shifted. If it is determined that the wearing position has shifted, the user US is notified or the ear temperature data D1 is corrected. This reduces the measurement error of the ear temperature due to the shift in the wearing position of the ear thermometer 1, making it possible to measure the ear temperature with high accuracy. Hereinafter, the measurement of the ear temperature in the temperature measurement system 100 and the determination of the deviation of the wearing position of the ear thermometer 1 will be described.

[0029] First, the user US wears the ear thermometer 1 on his / her ear, and operates the operation unit 22 of the terminal device 2 to instruct the ear temperature measurement program 231 to be started. When the operation unit 22 instructs the terminal device 2 to start the ear temperature measurement program 231, the control unit 21 starts the ear temperature measurement program 231 and executes the following processing in cooperation with the ear temperature measurement program 231.

[0030] First, the control unit 21 connects to the ear thermometer 1 via the communication unit 25 and instructs the ear thermometer 1 to start measurement. In response to an instruction from the terminal device 2, the ear thermometer 1 starts measurement by the first measurement unit 11 and the second measurement unit 12, and transmits the obtained ear temperature data D1 and outside air temperature data D2 to the terminal device 2 via the communication unit 15 in association with time information. When reception of the ear temperature data D1 and the outside air temperature data D2 from the ear thermometer 1 begins, the control unit 21 waits until the value of the ear temperature data D1 becomes substantially constant (the measurement result of the ear temperature becomes stable). When the value of the ear temperature data D1 becomes substantially constant, the control unit 21 starts the position shift determination process A.

[0031] 7 is a flowchart showing the flow of the positional deviation determination process A. The positional deviation determination process A will be described below with reference to FIG.

[0032] First, the control unit 21 receives (acquires) the ear temperature data D1 and the outside air temperature data D2 transmitted from the ear thermometer 1 via the communication unit 25, and stores the ear temperature data D1 and the outside air temperature data D2 in the memory unit 23 in association with time information (step S101).

[0033] Next, the control unit 21 determines whether or not a change greater than a predetermined gradient occurs in the ear temperature data D1 (step S102). For example, the control unit 21 analyzes the acquired ear temperature data D1, and if the average rate of change (absolute value) of the ear temperature data D1 over the most recent 30 seconds exceeds a predetermined threshold TH1 (e.g., 0.01°C / sec), it determines that the ear temperature data D1 has changed with a larger than predetermined slope. If the average rate of change of the ear temperature data D1 over the most recent 30 seconds is equal to or less than the predetermined threshold TH1, it determines that the ear temperature data D1 has not changed with a larger than predetermined slope.

[0034] Here, the threshold value TH1 may be a predetermined value, or may be changed according to the physical activity state of the user US obtained from a heart rate monitor, etc. For example, the threshold value TH1 may be divided into a positive direction and a negative direction, and if the heart rate increases when a temperature change is detected, the deep body temperature per unit time tends to increase, so the threshold value for the positive direction temperature change rate may be increased, and conversely, if the heart rate decreases, the deep body temperature tends to decrease, so the threshold value for the negative direction temperature change rate may be increased.

[0035] When it is determined that no change greater than a predetermined gradient has occurred in the ear temperature data D1 (step S102; NO), the control unit 21 proceeds to step S110.

[0036] If it is determined that a change greater than a predetermined slope has occurred in the ear temperature data D1 within a specified period (step S102; YES), the control unit 21 determines whether the amount of change in the ear temperature data D1 is within the outside air temperature influence range (step S103). For example, the control unit 21 determines the change in the ear temperature data D1 as the difference between the latest ear temperature data D1 and the average ear temperature data D1 for the previous minute as the change in the ear temperature data D1, and if the change in the ear temperature data D1 is equal to or less than a predetermined threshold TH2 (e.g., 0.3°C). If the difference between the latest ear temperature data D1 and the average ear temperature data D1 for the previous minute exceeds the predetermined threshold TH2, it determines that the change in the ear temperature data D1 is not within the range influenced by the outside air temperature. Here, generally, the range of the change in the ear temperature data D1 due to the influence of the outside air temperature is determined, and if the change in the ear temperature data D1 is outside the range influenced by the outside air temperature, it can be estimated that the temperature change is not due to the influence of the outside air temperature. The threshold TH2 for determining whether or not the temperature is within the range influenced by the outside air temperature may be changed depending on the difference between the outside air temperature and the ear temperature.

[0037] When it is determined that the amount of change in the ear temperature data D1 is not within the outside air temperature influence range (step S103; NO), the control unit 21 notifies an abnormality (step S104). If the change in the ear temperature data D1 is outside the range affected by the outside air temperature, an abnormality may have occurred, such as the ear thermometer 1 falling off from the ear. In this case, the control unit 21 notifies the user of the abnormality. Examples of methods for notifying an abnormality include displaying abnormality notification information (such as a message or icon notifying an abnormality) on the display unit 24, and outputting a message or a beep sound notifying an abnormality by the audio output unit 26.

[0038] Next, the control unit 21 sets the inner ear temperature data D1 of the target section as an abnormal value (step S105), and proceeds to step S110. The target section is, for example, a section in which the ear temperature changes more than a predetermined gradient in the ear temperature data D1. The control unit 21 sets the value of the target section of the ear temperature data D1 stored in the storage unit 23 as an abnormal value.

[0039] On the other hand, in step S103, if it is determined that the amount of change in the ear temperature data D1 is within the outside air temperature influence range (step S103; YES), the control unit 21 determines whether the amount of change in the outside air temperature data D2 is equal to or greater than a predetermined threshold value TH3 (e.g., 0.3°C) (step S106). For example, the control unit 21 determines the amount of change in the outside air temperature data D2 as the difference between the latest outside air temperature data D2 measured by the second measuring unit 12 and the average outside air temperature data D2 for the immediately preceding minute, and determines whether the amount of change in the outside air temperature data D2 is greater than or equal to a predetermined threshold value TH3 (e.g., 0.3°C). Here, it is preferable that the threshold value TH3 is a value determined according to the amount of change in the ear temperature data D1. Instead of step S106, it may be determined whether or not there is a peak in the outside air temperature data D2, and if there is a peak in the outside air temperature data D2, the process proceeds to step S107, and if there is no peak in the outside air temperature data D2, the process proceeds to step S108.

[0040] If it is determined that the amount of change in the outside air temperature data D2 is greater than or equal to a predetermined threshold value TH3 (e.g., 0.3°C) (step S106; YES), the control unit 21 determines that a change has occurred in the ear temperature data D1 due to the change in outside air temperature, corrects the ear temperature data D1 based on the outside air temperature data D2 (step S107), and proceeds to step S110. In step S107, a correction (called outside temperature correction) is performed to remove changes in the internal ear temperature data D1 caused by changes in the outside temperature. As the outside temperature correction, a known general outside temperature correction can be used. For example, as described in Japanese Patent No. 5270422, a method of correcting the internal ear temperature data D1 based on the outside temperature and a previously determined distance from the entrance of the ear canal to the first measuring unit 11 can be used, but the method is not limited to this.

[0041] If it is determined that the amount of change in the outside air temperature data D2 is below the predetermined threshold value TH3 (step S106; NO), the control unit 21 determines that the wearing position of the ear thermometer 1 has shifted, and notifies the user of the shift in the wearing position (step S108). Examples of methods for notifying the misalignment of the wearing position include displaying notification information of the misalignment of the wearing position on the display unit 24 as a notification unit, and outputting a message or a beep sound notifying the misalignment of the wearing position by the audio output unit 26 as a notification unit. The control unit 21 may also notify the ear thermometer 1 of information indicating the misalignment of the wearing position via the communication unit 25, vibrating the ear thermometer 1, or outputting a message or a beep sound notifying the misalignment by an audio output unit (not shown) provided in the ear thermometer 1.

[0042] Next, the control unit 21 performs offset correction on the inner ear temperature data D1 (step S109), and proceeds to step S110. For example, the control unit 21 takes the average temperature for a predetermined period (e.g., the previous 30 seconds) immediately prior to the point at which the temperature change is detected (e.g., the time when the slope of the ear temperature data D1 becomes equal to or greater than a predetermined slope) as the positive value, and corrects (replaces) the ear temperature data D1 for the section at which the temperature change is detected to the above average temperature. Alternatively, the control unit 21 may set the ear temperature data D1 stored in the memory unit 23 in a section where a temperature change is detected (for example, a section where the slope of the change in the ear temperature data D1 is equal to or greater than a predetermined slope) as an abnormal value and not record it.

[0043] In step S110, the control unit 21 determines whether or not a termination condition for the positional deviation determination process A is satisfied (step S110). The conditions for ending the position shift determination process A include, for example, when an abnormality is detected, when the operation unit 22 instructs the ear temperature measurement program 231 to end, when a predetermined measurement time has elapsed, and so on. When it is determined that the end condition of the positional deviation determination process A is not satisfied (step S110; NO), the control unit 21 returns to step S101. When it is determined that the end condition of the position shift determination process A is satisfied (step S110; YES), the control unit 21 ends the position shift determination process A.

[0044] <Second embodiment> Next, a second embodiment of the present invention will be described. The configuration of the temperature measurement system 100 in the second embodiment is the same as that in the first embodiment, and the description thereof will be used. In the second embodiment, the ear temperature measurement program 231 stored in the storage unit 23 of the terminal device 2 includes a program for executing a positional deviation determination process B, which will be described later. The control unit 21 executes the positional deviation determination process B in cooperation with the ear temperature measurement program 231. The positional deviation determination process B will be described below.

[0045] FIG. 8 shows the changes in the ear temperature data D1 acquired from the first measuring unit 11, the outside air temperature data D2 acquired from the second measuring unit 12, and the deep body temperature measurement data D3 in the stomach when the outside air temperature is changed by blowing wind from the outside around the worn ear thermometer 1. As shown in FIG. 8, when wind is blown for the period from time T1 to time T2 (5 minutes), the ear temperature data D1 drops after the outside air temperature data D2 drops. The deep body temperature measurement data D3 does not change. In other words, the change in the ear temperature data D1 is not due to a change in body temperature but due to the influence of the outside air temperature. In this way, the ear temperature data D1 changes after the outside air temperature data D2 changes due to the influence of the outside air temperature.

[0046] Therefore, in the position shift determination process B, the timing of changes in the ear temperature data D1 and the outside air temperature data D2 is used to determine whether or not the wearing position of the ear thermometer 1 has shifted. If it is determined that the wearing position has shifted, the user US is notified or the ear temperature data D1 is corrected. This reduces the measurement error of the ear temperature due to the wearing position shift, and enables the ear temperature to be measured with high accuracy. Hereinafter, the position deviation determination process B will be described with reference to FIG.

[0047] In the positional deviation determination process B, first, the control unit 21 executes the processes of steps S201 to S204. The processes of steps S201 to S203 are similar to steps S101 to S103 in the positional deviation determination process A, and therefore the same explanation will be used.

[0048] In step S203, when it is determined that the amount of change in the ear temperature data D1 is not within the outside air temperature influence range (step S203; NO), the control unit 21 executes the processes of steps S204 and S205, and proceeds to step S210. The processes in steps S204 and S205 are similar to steps S104 to S105 in the position shift determination process A, and therefore the same explanation will be used.

[0049] In step S203, if it is determined that the amount of change in the ear temperature data D1 is within the range influenced by the outside air temperature (step S203; YES), the control unit 21 determines whether the timing of the change in the outside air temperature data D2 precedes (is earlier than) the timing of the change in the ear temperature data D1 (step S206).

[0050] If the control unit 21 determines that the timing of the change in the outside air temperature data D2 precedes the timing of the change in the ear temperature data D1 (step S206; YES), the control unit 21 determines that a change has occurred in the ear temperature data D1 due to the influence of the change in outside air temperature, corrects the ear temperature data D1 based on the outside air temperature data D2 (step S207), and proceeds to step S210. The process of step S207 is similar to step S107 of the position shift determination process A, and therefore the same explanation will be used.

[0051] If it is determined that the timing of the change in the outside air temperature data D2 is later than the timing of the change in the ear temperature data D1 (step S206; NO), the control unit 21 determines that a shift in the wearing position of the ear thermometer 1 has occurred, notifies the user of the shift in the wearing position (step S208), applies an offset correction to the ear temperature data D1 (step S209), and proceeds to step S210. The processing in steps S208 to S209 is similar to steps S108 to S109 in the position shift determination processing A, and therefore the same explanation will be used.

[0052] In step S210, the control unit 21 determines whether or not a termination condition for the positional deviation determination process B is satisfied (step S210). The termination conditions for the position shift determination process B are similar to those for the position shift determination process A, for example, an abnormality is detected, the operation unit 22 instructs the ear temperature measurement program 231 to terminate, a predetermined measurement time has elapsed, etc. When it is determined that the end condition of the position shift determination process B is not satisfied (step S210; NO), the control unit 21 returns to step S201. When it is determined that the end condition of the position shift determination process B is satisfied (step S210; YES), the control unit 21 ends the position shift determination process B.

[0053] As described above, the control unit 21 of the terminal device 2 is provided in the ear thermometer 1 worn by the user US, and acquires ear temperature data D1, which is measurement data of the first temperature, from the first measurement unit 11 that measures a first temperature including the temperature inside the ear of the user US, and acquires outside air temperature data D2, which is measurement data of the second temperature, from the second measurement unit 12 that measures a second temperature including the temperature around the user US. Then, the control unit 21 determines whether or not the wearing position of the ear thermometer 1 has shifted, based on the change in the ear temperature data D1 and the change in the outside air temperature data D2. For example, the control unit 21 determines that a shift has occurred in the attachment position of the ear thermometer 1 when the slope of the change in the ear temperature data D1 exceeds a predetermined threshold, the amount of change in the ear temperature data D1 is within a predetermined range, and the amount of change in the outside air temperature data D2 is below a predetermined threshold. In addition, for example, the control unit 21 determines that a shift has occurred in the attachment position of the ear thermometer 1 if the slope of the change in the ear temperature data D1 exceeds a predetermined threshold, the amount of change in the ear temperature data D1 is within a predetermined range, and the timing of the change in the ear temperature data D1 is earlier than the timing of the change in the outside air temperature data D2. Therefore, if the ear thermometer 1 is misaligned, the misalignment can be detected, making it possible to prompt the user to re-attach the ear thermometer 1 to the correct position or to correct the measurement results, thereby preventing a decrease in measurement accuracy due to the ear thermometer 1 being misaligned.

[0054] Also, for example, when the control unit 21 determines that the wearing position of the ear thermometer 1 is shifted, it notifies the user US. Therefore, the user US can be made aware of the shift in the wearing position and can be prompted to wear the ear thermometer 1 in the correct position.

[0055] Furthermore, if the control unit 21 determines that the ear thermometer 1 is misaligned, it applies offset correction to the ear temperature data D1 acquired from the first measurement unit 11. Therefore, it is possible to obtain correct ear temperature data D1 by correcting the erroneous ear temperature data D1.

[0056] The contents described in the above embodiment are preferred examples of the information processing device, temperature measuring device, temperature measuring system, method for determining misalignment of mounting position, and program according to the present invention, and are not limited to these. For example, in the above embodiment, the functions of the information processing device of the present invention are provided in a terminal device 2 such as a smartphone or a smartwatch, but the present invention is not limited to this. For example, the functions of the information processing device of the present invention may be provided in an ear thermometer 1 (temperature measuring device).

[0057] In the above embodiment, the second sensor is provided in the ear thermometer 1. However, the second sensor may be separate from the ear thermometer 1.

[0058] In the above embodiment, a semiconductor memory such as a ROM or a hard disk is used as a computer-readable medium for the program according to the present invention, but the present invention is not limited to this example. As other computer-readable media, a portable recording medium such as a CD-ROM can be applied. Furthermore, a carrier wave can be applied as a medium for providing data of the program according to the present invention via a communication line.
