<Normal health management and processing flow based on body temperature information>
As described above, the second temperature measuring unit including the IC tag (RFID) 100 having the temperature measuring unit on the subject P is inserted into the external auditory canal with respect to the subject P, or a hook-and-loop fastener is attached. It is enclosed with an enveloping member, and is attached or pasted at a proper position on the body so that the IC tag 200 comes into contact with the diaper which can be detachably attached or provided on a wristband. The measurement is started by starting the measurement of the measurement start time or by inputting a measurement start time setting (time setting) instruction using the input unit 14, the function key 14a, or the like. For the body temperature information, a time condition set in advance by the input unit 14, for example, a second temperature measuring unit including an IC tag (RFID) 100 having a temperature measuring unit is attached to the subject P and a measurement start instruction is input. For example, after 5 minutes, the IC tag reading unit 13 transmits an electromagnetic wave having a predetermined frequency, for example, 13.56 MHz to the IC tag 100 (in this case, for example) The transmission / reception distance is about 3 cm to 10 cm), and body temperature information of the temperature sensor 106 obtained in synchronization with the signal is read (step S1). The measured body temperature information is stored in the storage unit 15 (step S2). This body temperature information is compared with a threshold value (step S3). For example, in the case of body temperature, the upper limit value is 37.0 ° C. and the lower limit value is 35.5 ° C. If it is determined that the body temperature information is abnormal (including abnormalities during measurement), an alarm is generated (step S4). When the measurement is completed, a buzzer, a vibrator, light, etc. are notified (step S5). If there is an abnormality, “fever” is displayed on the display unit 11, and the pulse and blood oxygen saturation (SPO ₂ ) measured by the pulse oximeter are also displayed (see FIG. 3). If necessary, a note to that effect is input by the input unit 14 and stored in the storage unit 15. If abnormal, reset as necessary (step S6), return to step S1, and measure the body temperature again. When there is no abnormality, the measured body temperature is memorized and displayed on the display unit 11, and then the operation is terminated (see FIG. 3). The body temperature is preferably displayed on the display unit 11 together with the measurement date. When fever occurs, the body temperature trend for the predetermined time shown in FIG. 4, for example, 24 hours in winter, and a pulse oximeter, the pulse during measurement, and the blood oxygen saturation (SPO ₂ ) are displayed in an overlapping manner. Then, respiratory diseases due to infections such as influenza and RS (Respiratory Syncytial) virus can be easily grasped.

Information such as body temperature, blood pressure, memo input, and blood glucose stored in the storage unit 15 can be displayed on the display unit 11 for a predetermined period, for example, 30 days, as shown in FIG. The cursor can be moved.

<Other functions and operations>
Other functions and operations will be described in detail below.
(1) Time setting When the terminal device 5 is turned on or a battery (not shown) is inserted into the portable terminal 50, it is necessary to include the current year / month / day / hour and its sum value from the ROM 16 which is a nonvolatile memory. Read the data. When the terminal device 5 is turned on or while the battery is inserted in the portable terminal 50, a signal is sent to the arithmetic processing unit 10 once every hour from the clock (timer) in a process not shown. When the arithmetic processing unit 10 receives the signal, it writes the current year / month / day / hour in the ROM 16.

  Next, the read sum value of the current year, month, date, and hour is calculated, and it is confirmed whether it is equal to the read sum value. If they are equal, the process proceeds to the SLEEP state. If they are not equal, it is determined that the read value is invalid, and the error flag FLAGerr is set (= 1).

Next, it waits in the SLEEP state until the power is turned on.

When the power is turned on, FLAGerr is confirmed, and if it is a predetermined condition, for example, if it is other than 1, the operation proceeds to a temperature detecting operation. If FLAGerr is 1, the process proceeds to date / time input processing. Here, a screen prompting the user to input the date / time is displayed, and the user inputs the current year / month / date / time according to the screen. As another method, regardless of the value of FLAGerr, a method of always shifting to the date / time input process when the power is turned on for the first time after inserting the battery is also conceivable. In this case, the sum value and sum check functions are unnecessary. Further, by providing the radio timepiece, the sum value and sum check functions become unnecessary. In this way, the user can quickly and easily set the year, month, day, hour, and minute, and even if the current year, month, day and hour of the EEPROM is damaged, the subject P can quickly set the correct date. Yes. Thus, the set current time is displayed on the display unit 11 by the calendar function based on the clock function and the calendar. That is, while AM and PM indicating AM and PM are displayed, the current time is displayed, and the date is updated every time the time count by the clock function elapses 24 hours, and this date is displayed on the display unit 11 by the calendar function. Is done. In addition, “year” may be displayed on the display unit 11.

(1) Measurement mode when using the second temperature measuring unit The measurement mode is entered when the power switch is turned on or when the function key 14a is reset. In this measurement mode, the measurement value of the current day is displayed in the initial state.
Measurement start conditions:
In the measurement mode, when the temperature measuring unit is attached to the subject P, the temperature measuring unit starts to warm. Initially, at a predetermined interval, for example, every 10 seconds, an electromagnetic wave (13.25 MHz) having a predetermined frequency is generated from the IC tag reader as a read signal for reading, and temperature data is sampled. In the feminine body temperature measuring device, if the sample data exceeds 30 ° C. and the rate of temperature increase is a predetermined value, for example, 0.25 ° C./4 seconds (moving average value) or more, the body temperature is measured from that time as a starting point. To start.

When the measurement is started, the temperature is detected by the temperature sensor 106 every predetermined sampling period (for example, 10 seconds), the A / D converted temperature is sampled, and the body temperature is measured by a predetermined method based on the sample data. Here, the peak hold method is used for measurement. In the peak hold method, the temperature is periodically sampled, and the highest value among the sampled temperatures is held in the storage unit 15. The measurement is terminated when the rate of increase of the sample data becomes a predetermined value, for example, 0.019 ° C./16 seconds or less, and the highest value obtained at that time is stored as a measurement value in the storage unit 15 by the CPU 10. (Alternatively, the measurement may be ended after elapse of a predetermined time, for example, 5 minutes from the start of measurement.) The sample data used for the measurement does not use the measurement value from the temperature sensor 106 as it is, and as the sample data at a certain time point, the arithmetic addition average of the three sample data is obtained by adding the data itself and the front and back thereof, and this is calculated at that time point Used as sample data. By doing so, it is possible to perform measurement more accurately while suppressing variations in sampling. When one measurement is completed in this manner, a notification to that effect is notified by a buzzer, vibrator, light, and voice by the notification unit, and the measurement value is read from the storage unit 15 by the CPU 10 and displayed on the display unit 11. The If it is determined that there is an abnormality and heat generation is recognized, a note indicating that “heat generation” has occurred is entered using the function keys 14 a and the input unit 14. In addition, the blood pressure value (maximum blood pressure / minimum blood pressure) measured separately and medication information are also input together with the function key 14a and the input unit 14. An example of trend display of input and stored information is shown in FIG.

<Other usage patterns>
It can use as a normal electronic thermometer using the portable terminal 50 and 1st temperature measuring part which are used for the nursing facility of this invention and / or the monitoring apparatus in the home. In this case, when the temperature is measured for a predetermined time (about 1 to 5 minutes) by attaching the first temperature measuring unit to an appropriate place on the body of the infant P, the temperature information is stored in the EEPROM 202 together with the time. The The stored body temperature information is stored in the storage unit 15 of the portable terminal 50 from the external transmission unit 203 via the connection terminal 12a (a reading start switch or the like may be provided to instruct reading start). The maximum value of the stored body temperature information is displayed on the display unit 11 as the measured body temperature.
