FIG. 3 is a diagram showing a body temperature acquisition processing flow, and FIG. 4 is a diagram showing a display example. The present invention is not limited to the examples, and the temperature measuring unit may be a pasting type in which the outside is surrounded by a heat insulating member.

In FIG. 1, reference numeral 1 denotes a temperature measuring unit that incorporates an IC tag 100 having a temperature measuring unit and is formed of an elastomer or the like in a liquid-tight manner. In order to prevent accidental ingestion during measurement, the outer diameter is about 1.5 to 2.0 cm and the thickness is about 3.0 to 5.0 mm. The weight is about 0.5 to 1.0 gw. The IC tag 100 having a temperature measuring unit is fixed with a synthetic adhesive such as an epoxy resin.

The subject (woman, woman) P takes out the temperature measuring unit 1 from the main body 50 and measures the temperature measuring unit 100 in her mouth. The main body 50 stores a control unit (CPU) 10, a display unit 11, an external communication unit 12, an IC tag reading unit 13, an input unit 14, a storage unit 15, a clock unit 16, a processing flow, and the like, and can be read by a computer. It includes a RAM 17 and a ROM 18 that store programs. The main body 50 and the management site / medical site and membership-based service site (not shown) can transmit information to each other via the external communication unit 12 and an information communication network (not shown). In addition, it is convenient that the clock unit 16 is time-corrected by receiving a radio wave, and it is convenient to adjust the time by providing a radio clock function.

The input unit 14 can also input medication (prescription) information and physiological information such as menstruation as a memo input when used by women. The IC tag reading unit 13 generates an electromagnetic wave of 13.56 MHz after a predetermined time, for example, 5 minutes after the subject (woman) gets in the mouth, and reads the body temperature information. The end of the measurement may be detected when the temperature measuring unit 100 is taken out from the main body (case) 1 and the elapsed time (minutes) is detected by the clock 16 using that as a base point.

<Configuration of IC tag>
In FIG. 1, reference numeral 101 denotes a RAM which is a computer-readable storage medium that stores a program that receives a signal from the IC tag reading unit 13 and operates the logic unit 110 in a predetermined flow. An EEPROM 102 stores an offset value, a temperature correction value, and the like corresponding to each temperature sensor 106. In addition, measured body temperature information, information on the subject P, and the like can be stored. The logic unit 110 may be a CPU that can control a more complicated processing flow.

The temperature sensor 106 outputs an analog output almost linearly with respect to the temperature change, and can be miniaturized and integrated with an IC tag, with a temperature resolution of 0.1 to 0.05 ° C. between 32 to 42 ° C. A semiconductor type temperature sensor such as a C-MOS temperature sensor is preferably used, but a thermistor type or a thermopile (thermocouple) type is also possible. When used as a thermometer for women, a semiconductor type temperature sensor having a temperature resolution of 0.05 ° C. between 35 ° C. and 38 ° C., such as a C-MOS temperature sensor, is preferably used, but thermistor type, thermopile (thermoelectric It is also possible with the pair type. Reference numeral 103 denotes a transmission / reception circuit for acquiring body temperature information of an IC tag (RFID) 100 having a temperature measurement unit provided in the subject P, 103a denotes an antenna, and 104 denotes a power supply unit. The power supply unit 104 supplies power to each unit of the IC tag 100 having the temperature measurement unit when the body temperature information is read through the antenna unit 103a having a coil. Reference numeral 107 denotes an A / D converter, which A / D converts a body temperature signal generated by the temperature sensor 106 and an oscillation circuit (not shown).

The IC tag 100 has a size of about 5 mm × 5 mm and a thickness of about 1.5 mm including the antenna 103a. The IC tag 100 may be any frequency as long as it can communicate (transmit / receive) with an electromagnetic wave having a frequency that can pass through a living body, but preferably can transmit with an electromagnetic wave of 13.56 MHz. . Further, it is possible to prevent the acquisition of incorrect information about the subject P, or to provide a security function by enabling encryption processing of a signal output from the antenna 103a.

<Processing flow for acquiring body temperature information>
The measurement starts when the subject P takes out the temperature measuring unit 1 from the main body 50, or starts counting the measurement start time or inputs a measurement start instruction at the input unit 14 or the like. The body temperature information includes time conditions set and input in advance by the input unit 14, for example, when the temperature measuring unit 1 is taken out from the main body 50, when a measurement start instruction is input, when a predetermined temperature rise is confirmed, and the like. As a base point, for example, an electromagnetic wave of 13.56 MHz or 860 to 960 MHz (UHF band) is transmitted from the IC tag reading unit 13 to the IC tag 100 after 5 minutes (the transmission / reception distance is about 10 cm to 1 m) and synchronized with the signal. The body temperature information of the temperature sensor 106 obtained in this manner is read (step S1). The 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. as default values. The upper limit value and the lower limit value may be changeable according to the subject P. 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). When there is an abnormality (for example, basal body temperature at the time of fever), “fever” is displayed on the display unit 11, a note to that effect is input by the input unit 14, and the storage unit 15 stores it. If abnormal, reset as necessary (step S6), return to step S1, and measure the body temperature again. If there is no abnormality, the measured body temperature is stored, and the body temperature measurement is terminated.

Information such as body temperature and memo input stored in the storage unit 15 is displayed as a trend on the display unit 11 as shown in FIG. Such information, together with the ID of the subject P, is encrypted and transmitted over the Internet, a dedicated LAN, etc. to the server of a health-related service provider or a medical site such as the attending physician, and if necessary, such as comments from the attending physician You can get advice.

<Operation and function of female thermometer>
The operation and function of the female thermometer will be described in detail below.
(1) Measurement mode When the power switch 20 is turned on or reset with the cancel key 21, the measurement mode is entered. In this measurement mode, the measurement value of the current day indicated by the clock 16 in the initial state is displayed. Further, by operating the + key or the-key of the body temperature display / movement key 22, a memo display bar (not shown) corresponding to the memo item set as the date data is displayed together with the measured value of the specified day. . In this measurement mode, the measurement value from the temperature sensor 106 is monitored, and body temperature measurement is started if the next measurement start condition is satisfied (not limited to this measurement start condition).
Measurement start conditions:
In the measurement mode, when the subject P holds the temperature measuring unit 1 in the mouth, the temperature measuring unit 1 starts to warm in the mouth. After being put in the mouth, at first, for example, every 10 seconds, an electromagnetic wave (13.56 Mz) is generated from the IC tag reader as a read signal for reading, and temperature data is sampled. In the body temperature measuring apparatus for ladies, when the sample data exceeds 30 ° C. and the rate of temperature increase is 0.25 ° C./4 seconds (moving average value) or more, body temperature measurement is started from that point.

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, a vibrator, and light, and a measured value is read from the storage unit 15 by the CPU 10 and displayed on the display unit 11. When it is determined that there is an abnormality and heat generation is recognized, a note is input on the input unit 14 that “heat generation” has occurred. By doing so, discrimination from body temperature in the high temperature period becomes possible.

(2) In the memo mode measurement mode, when the memo key constituting the key panel as the input unit 14 is pressed, the mode transits to the memo mode. When this mode is entered, notes related to six items of physiological items such as menstrual memo, fever memo, menstrual pain, cage, intercourse, etc. can be input for the date set in the measurement mode. Each time the memo key is pressed, the items to be set are shifted sequentially. At that time, the memo display bar corresponding to the item currently set is flashed. The subject P can know the item to be set by looking at the blinking display. When the confirmation key is pressed for each item, the fact that the memo item has been set is stored, a memo display bar corresponding to the item is displayed, and the measurement mode is restored. Also, no item is confirmed, and the measurement mode is returned to when the sixth memo key is pressed. The memo item set in this way is read for each date specified in the measurement mode, and a memo display bar corresponding to the set item is displayed.

(3) Estimated date display mode When the function key 23 is pressed in the measurement mode, the mode shifts to the estimated date display mode. When entering this mode, the next ovulation date is first displayed from the various data already calculated and stored. There are a total of three items displayed in this mode, and each time the function key is pressed, the displayed items shift to the next menstruation date and the scheduled delivery date, and the measurement mode is returned to the third function key.

(4) Data processing mode This mode is a mode for executing data processing. In this mode, transition is made when the power switch 20 is turned off or after 5 hours have elapsed from the set time of the alarm. However, data processing is only performed once a day, and if the mode is shifted to this mode more than once a day, the data processing is not performed in the second and subsequent times, and the processing ends immediately and the stop mode is entered. Migrate to

The mode of the present embodiment is the above mode. When the cancel key is pressed in each mode, the measurement mode is restored. In each mode other than the measurement mode, the time elapsed without key input is measured, and when a predetermined time elapses, the state returns to the same state as when the cancel key is pressed. Similarly, when a predetermined time elapses in the measurement mode, the mode automatically shifts to the stop mode. Further, the key input for transitioning from the measurement mode to each mode is considered to be input when the key is pressed for a predetermined time in order to prevent erroneous input.

<Contents of data processing>
In the data processing mode, the accumulated measurement value is used to determine the first day of menstruation, and if the first day of menstruation is updated from the previous date, the latest menstrual period from the first day of menstruation before the update to the day before the first day of menstruation is updated. In addition to obtaining the average high-temperature phase period and average low-temperature phase period for the cycle, the average menstrual cycle and reference body temperature are calculated using data on past menstrual cycles accumulated so far. Further, it is determined whether the day of measurement (hereinafter referred to as today) is a high-temperature phase or a low-temperature phase, an ovulation day is detected, and an average body temperature is calculated. Finally, these data are used to predict the next menstruation date, the next ovulation date, and the expected birth date.

The feminine body temperature measuring device predicts (estimates) the next ovulation day and menstrual day with high accuracy when in a certain menstrual cycle, and also predicts the expected delivery date if it is determined to be pregnant from the measurement results It is possible to (estimate).

(1) The calculation timing calculation process is performed once a day by shifting to the data processing mode when the power switch 20 is turned off or after the wake-up alarm set time has elapsed 5 hours. After the second time, nothing is performed and the process ends. It is assumed that the initial value of the wake-up time is set at exactly 6:00 am. Next, the process in each step will be described in more detail.

(2) Menstruation first day determination / When menstruation memo input continues for a predetermined number of days or more, for example, three days or more, the first day of menstrual memo input is determined to be the menstrual first day. When it is less than a predetermined number of days, for example, less than 3 days, it is considered as a physiological misperception.
・ If there is no menstrual memo and the low temperature phase is started, the start date of the low temperature phase is the first day of menstruation. However, if the menstrual memo is input before the high temperature phase is started, the first menstrual period is corrected.

(3) Average menstrual cycle (not shown)
・ The period from the first day of menstruation to the day before the first day of menstruation is the menstrual cycle.
-The average menstrual cycle is calculated after the first day of menstruation is confirmed, and the calculation result is retained until the next menstruation day is confirmed.

-The low temperature phase period is valid for a predetermined number of days, for example, 5 days to 30 days. Ineffective low-temperature phase periods are excluded from the calculation. In addition, when there is no more than a predetermined number (three) of effective low-temperature phase periods in a predetermined menstrual cycle, for example, in the June menstrual cycle, or when the average low-temperature phase period is not valid as a result of calculation, the average low-temperature phase period data is Make it not exist.

(6) Next menstruation schedule (display)
-The next menstrual day is calculated after the calculation of the average menstrual cycle and the average high temperature phase period is completed after a predetermined period, for example, the fourth menstrual first day has been determined.
The next menstrual day is calculated (estimated) as a predetermined period, for example, a period of 3 to 7 days (XX month XX day to XX month XX day).
-If the day of this calculation process is a low-temperature phase (determined by phase determination described later) Next menstrual day = recent menstrual first day + average menstrual cycle-possible period-recent menstrual first day + average menstrual cycle + possible period To do. However, the possible period is assumed to be equivalent to 1.5σ / 2, with the distribution of the menstrual cycle used for calculating the average menstrual cycle as a normal distribution. The possible period is rounded to the first decimal place.・ When the day of this calculation is the high-temperature phase (determined by the phase judgment described later) Next menstruation day = recent ovulation date + average high-temperature phase period−possible period to recent ovulation date + average high-temperature phase period + possible Period. However, the possible period is equivalent to 1.5σ / 2, assuming that the distribution of the high temperature phase period used for the calculation of the average high temperature phase period is a normal distribution. The possible period is rounded to the first decimal place.

When the next menstruation estimated in this way is displayed on the display unit 11, display control is performed as follows according to the conditions on the display day.
-When the display day is not included in the period of the next period, the calculated next period is displayed as it is.
-If the display date is within the period of the next menstruation period, and if it is a predetermined number of days before the last day of the period, for example, 3 days ago, the period displayed is from the date of the display day to the next period The last day of the period. That is, from the display date to the latest menstrual first day + average menstrual cycle + possible period, or from the date of display to the latest ovulation date + average high-temperature phase period + possible period.
When the display day is the last day of the next menstrual day-after the third day, the display is from the date of the display day to the date of the display day + 3 days until the first day of menstruation.
-As a result of the calculation, when the next menstruation period is a predetermined number of days, for example, a period of 8 days or more, the display is "--month--day --- month--day".
-When the display day is the high temperature phase and the number of days from the ovulation date is a predetermined number of days, for example, 17 days or more, the display is "--month--day to --- month--day".
・ If the average menstrual cycle or average high-temperature phase period has not been established, the display shall be "--month--day to --- month--day".

(7) Reference body temperature (not shown)
The reference body temperature is calculated as Reference body temperature = (High temperature phase average body temperature for past predetermined times (for example, 3 times) + Low temperature phase average body temperature for past predetermined times (for example, 3 times)) / 2. However, the high temperature phase average body temperature and the low temperature phase average body temperature are obtained by the average body temperature.

(8) Average body temperature (not shown)
As the average body temperature, each of the high-temperature phase average body temperature and the low-temperature phase average body temperature is calculated after the first physiological first day is determined.
The high-temperature phase average body temperature is calculated based on the body temperature up to a predetermined day, for example, 3 days before the start of the low-temperature phase, with the body temperature on the predetermined day, for example, the third day, from the start of the high-temperature phase as an initial value.
For the low-temperature phase average body temperature, the body temperature on the predetermined day, for example, the third day from the start of the low-temperature phase is used as an initial value, and the average body temperature is calculated by the body temperature up to a predetermined day, for example, three days before the high-temperature phase.

(9) Phase judgment (not shown)
Determine the phase of the day of measurement.・ If body temperature on the day ≥ reference body temperature, the body temperature is set to hyperthermia.
・ If the body temperature of the day <the reference body temperature, hypothermia.
The phase determination is performed every predetermined day, for example, every day after the low temperature phase is first confirmed from the start of recording.
-If hypothermia continues for a predetermined number of days on the day, for example, 3 consecutive days, the low temperature phase starts from a predetermined number of days, for example, 2 days. Alternatively, when the first day of menstruation is confirmed, the low temperature phase starts from the menstruation start date.
If the hyperthermia continues for a predetermined number of days, such as 3 days, on the same day, the high temperature phase starts from a predetermined number of days, such as 2 days. However, when there is a fever memo input within a predetermined number of consecutive days, for example, within 3 days, or when the body temperature is 37.5 ° C. or higher, the measurement result is excluded from the calculation.

(10) Ovulation day detection (not shown)
・ The ovulation date is calculated after the start date of the high temperature phase is updated in the phase determination.
・ Ovulation date is the last day of the low-temperature phase.
Ovulation date = high temperature phase start date -1

(11) Next ovulation day schedule (display)
The next ovulation day is calculated (estimated) after the calculation of the average menstrual cycle and the average low-temperature phase period after a predetermined number of times, for example, the fourth menstrual first day is determined. Since it cannot be calculated in the sections a to d, “−−month−−day −−− month−−day” is set.
-The next ovulation day is displayed as a predetermined period, for example, a period of 3 to 7 days (XX month XX day to XX month XX day).
・ If the day is the low temperature phase,
Next ovulation date = recent menstrual first day + average low-temperature phase period-possible period to recent menstrual first day + average low-temperature phase period + possible period. However, the possible period is assumed to be 1.5σ / 2, assuming that the distribution of the low temperature phase period used for the calculation of the average low temperature phase period is a normal distribution. The possible period is rounded to the first decimal place.
・ If the day is the high temperature phase,
Next ovulation date = recent ovulation date + average menstrual cycle−possible period to recent ovulation date + average menstrual cycle + possible period. However, the possible period is assumed to be equivalent to 1.5σ / 2, with the distribution of the menstrual cycle used for calculating the average menstrual cycle as a normal distribution. The possible period is rounded to the first decimal place.

When displaying the next ovulation date estimated in this way, display control is performed as follows according to the conditions on the display day.
・ If the displayed date is not included in the next ovulation date period, the calculated next ovulation date is displayed as it is.
-If the current day is within the calculated period of the next ovulation, and the period from the last day of the period to a certain day before, for example, 3 days before, the displayed period is from the date of the displayed day to the period of the next ovulation day. The last day. That is, from the display date to the latest physiological first day + average low-temperature phase period + possible period, or from the display date to the latest ovulation date + average menstrual cycle + possible period.
-If the display day is the last day of the next ovulation day-after the third day, the display will be from the date of the display day to the date of the display day + 3 days until the ovulation day.
-As a result of the calculation, when the next ovulation day is a predetermined number of days, for example, 8 days or more, the display is "--month--day to --- month--day".
When the day is a high temperature phase and the number of days from ovulation is a predetermined number of days, for example, 17 days or more, the display is "--month--day to --- month--day".
• If the average menstrual cycle or average low-temperature phase period has not been established, the display shall be "--month--day to --- month--day".

(12) Expected delivery date prediction (display)
When the number of days from the last ovulation day exceeds a predetermined number of days, for example, 20 days, and that day (latest measured body temperature) is a hyperthermia, it is estimated by the following equation.
Expected delivery date = ovulation date + 265 days-If the expected delivery date is not requested, the display shall be "--month--day to --- month--day".

(13) Missing data of measured body temperature (forgotten) Post-treatment basal body temperature should be measured every day in principle, but if data is missing due to forgetting to measure, missing as internal data Calculated from the measured body temperature before and after. However, the missing data is not displayed, and the temperature display on the missing date is “−−.−− ° C.”. The missing data is compensated so as to linearly interpolate the measured value immediately before and after the missing value. That is, the following example. If the measured body temperature data is missing for one day (the Nth day), if the measured value on the (N-1) th day is a and the measured value on the (N + 1) th day is b,
Date | N-1 day | N day | N + 1 day body temperature | a | a + (ba) / 2 | b
・ When the measured body temperature data is missing for 2 days (day N, day N + 1)
Date | N-1 day | N day | N + 1 day | N + 2 day body temperature | a | a + (ba) / 3 | a + 2 (ba) / 3 | b
Similarly, when the measured body temperature data is missing for m days, the body temperature on the missing day n = a + n (ba) / (m + 1)
The number of consecutive days m of the measured body temperature missing data is allowed up to a predetermined number of days, for example, up to 8 days. If there is an omission that exceeds the predetermined number of days, for example, 8 days, the body temperature data is invalidated by going back to the latest menstrual day.
When the valid data of the measured body temperature is not less than a predetermined ratio of the number of days in the menstrual cycle, for example, 50% or more, the data in the menstrual cycle is valid. When the ratio is less than a predetermined ratio, for example, less than 50%, the data in the menstrual cycle is invalidated.

<Contents of data processing>
In the data processing mode, the accumulated measurement value is used to determine the first day of menstruation, and if the first day of menstruation is updated from the previous date, the latest menstrual period from the first day of menstruation before the update to the day before the first day of menstruation is updated. In addition to obtaining the average high-temperature phase period and average low-temperature phase period for the cycle, the average menstrual cycle and reference body temperature are calculated using data on past menstrual cycles accumulated so far. Further, it is determined whether the day of measurement (hereinafter referred to as today) is a high-temperature phase or a low-temperature phase, an ovulation day is detected, and an average body temperature is calculated. Finally, these data are used to predict the next menstruation date, the next ovulation date, and the expected birth date.

<Judgment / correction process for menstrual first day>
When the menstruation memo input is continued for a predetermined number of days or more, for example, three days or more, the first day of the menstrual memo input is determined as the menstrual first day. When it is less than a predetermined number of days, for example, less than 3 days, it is considered as a physiological misperception.
・ When there is no physiology memo and the low temperature phase is started, the start date of the low temperature phase is set as the first day of menstruation. However, if the menstrual memo is input before the high temperature phase is started, the first menstrual period is corrected.
