Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woman's thermometer for measuring a basal body temperature.

[0002]

2. Description of the Related Art A woman's basal body temperature periodically has two phases, a high temperature phase and a low temperature phase, and a woman's thermometer is used to measure the basal body temperature. By recording the basal body temperature daily with a woman's thermometer and creating a trend graph, the measurer can know the cycle of the high-temperature phase and the low-temperature phase. In order to accurately record the trend of the basal body temperature, a digital female thermometer is also used to eliminate a reading error by a measurer. With a digital-type woman's thermometer, it is not only to measure body temperature, but also to record the measured body temperature and create the trend graph itself. Some have an estimation function of estimating the next scheduled ovulation date based on the day.

[0003]

However, in the conventional female thermometer having such an estimation function, the accuracy of the estimation cannot be improved unless the accuracy of the judgment on the first day of menstruation, which is the reference, is sufficiently high. For this reason, it was necessary to determine the first day of menstruation with sufficient accuracy.

The present invention has been made in view of the above-mentioned conventional example, and has as its object to provide a woman's thermometer capable of judging the first day of menstruation with high accuracy.

[0005]

According to the present invention, there is provided a body temperature measuring means for measuring a basal body temperature, an input means for inputting physiological data, and a physiological data as physiological data by the input means. When a predetermined number or more of memos are continuously input, a determination means for determining the first day as the first day of menstruation is provided.

It includes a schedule display bar 33a for displaying a date estimated based on the measurement result of the basal body temperature, such as a scheduled birth date. Also included is a memo display bar 33b for indicating each memo item, such as a physiological memo or a fever memo, which is input in association with the measurement of the basal body temperature. Although FIG. 2 shows a state in which all the display bars 33a and 33b are displayed,
These are not all displayed at the same time, and each display bar is displayed when the corresponding item is displayed or input.

The key panel 34 as an input unit is provided with various keys such as a power key, a memo key, a function key, an enter key, a body temperature display / move key (+ and-keys), an alarm key, and a cancel key. ing. In addition, item names indicating what each display bar means are described corresponding to each of the above-mentioned display bars.

FIG. 1 is a block diagram showing the overall configuration of a thermometer (women's thermometer) for controlling the temperature measurement by the thermometer of FIG.

In FIG. 1, a CPU 41 executes a predetermined program to control the entire apparatus, measures a body temperature in a procedure described later, and obtains various intermediate data and estimated values based on the measurement result. The clock 8 is a clock that ticks real time. The display unit 7 is a liquid crystal panel or the like, and measures a measured body temperature,

If a non-volatile rewritable memory is used for the storage units 421 to 422, there is no need to back up with a battery. The ROM 43 stores a program 431 executed by the CPU 41 in addition to the fixed data. The thermometer can also be connected to a host device (not shown) via the host interface 45.

<Functions of Woman Thermometer> FIG. 3 is a state transition diagram showing transitions of function modes for performing various functions by the present woman thermometer, such as measurement of body temperature, input of memos, calculation and display of estimation results, and the like. . (1) Stop mode When the power switch is turned off or a predetermined time has elapsed after the power is turned on, the stop mode is set. Even when the thermometer is turned off, the power of the entire circuit is not cut off. The input section 44 and the input timer 44 for performing the functions in the alarm timer such as the clock 8 and the CPU 41 and the data processing mode. Display unit 7, body temperature measurement unit 1, sensor unit 3
Electric power is supplied to portions other than 2a, etc., slightly.
In the stop mode, power is supplied only to a part necessary for restart in this way. (2) Measurement mode The measurement mode is entered when the power switch is turned on or when reset by the cancel key. In this measurement mode, the measurement value of the current day indicated by the clock 8 is displayed in the initial state. By operating the + or-key of the body temperature display / movement key, the memo display bar 33b corresponding to the memo item set as the data of the day is displayed together with the measured value of the specified day. In this measurement mode, the measurement value from the sensor unit 32a is monitored.
If the measurement start condition is satisfied, the body temperature measurement is started. (3) Memo mode In the measurement mode, the key panel 3 as the input unit 44
When the memo key constituting No. 4 is pressed, the mode transits to the memo mode. When entering this mode, memos relating to six physiological items, such as a physiological memo and a fever memo, can be input for the date set in the measurement mode. Each time the memo key is pressed, the items to be set shift sequentially. At this time, the memo display bar 33b corresponding to the item currently set is blinked. The operator can know the item to be set by looking at the blinking display. When the enter key is pressed for each item, the fact that the memo item is set is stored, the memo display bar 33b corresponding to the item is displayed, and the process returns to the measurement mode. Also, if no item is determined and the sixth memo key is pressed, the process returns to the measurement mode.

The memo items set in this way are read out for each date specified in the measurement mode, and a memo display bar 33b corresponding to the set items is displayed. (4) Estimated date display mode When the function key is pressed in the measurement mode, the mode transits to the estimated date display mode. When this mode is entered, the next ovulation date is first displayed from various data already calculated and stored. There are three items displayed in this mode,
The item displayed every time the function key is pressed is the next period,
It moves to the expected date of delivery and returns to the measurement mode with the third function key. (5) Data processing mode This is a mode for executing data processing described later. This mode shifts when the power switch is turned off or after 5 hours have passed from the set time of the alarm. However, data processing is performed only once a day. If you switch to this mode more than once a day,
In the second and subsequent times, no data processing is performed, and the processing is immediately terminated and the mode shifts to the stop mode.

The modes of the female thermometer of the present embodiment are the above five modes. When the cancel key is pressed in each mode, the mode returns to the measurement mode. In each mode other than the measurement mode, the time elapsed without any key input is measured, and after a predetermined time elapses, the state returns to the same state as when the cancel key is pressed. When a predetermined time elapses in the measurement mode, the mode automatically shifts to the stop mode. The key input for transitioning from the measurement mode to each mode is regarded as being input when the key is pressed for a predetermined time to prevent erroneous input.

<Body Temperature Measurement Sequence> In the measurement mode, when the user inserts the sensor section 32a at the tip of the probe 32 into the mouth to start measuring the body temperature, the body temperature measurement section 1
Starts the measurement of the body temperature according to a predetermined procedure based on the temperature input from the sensor unit 32a. When the measurement is completed, the measured value obtained is stored in the RAM 42. For this purpose, the body temperature measuring section 1 samples temperature data detected by the sensor section 32a at predetermined time intervals. When the sample data exceeds 30 ° C. and the temperature rise rate becomes 0.25 ° C./4 seconds or more, the main body thermometer starts measuring the body temperature starting from that time.

When the measurement is started, the temperature detected by the sensor section 32a is sampled every predetermined sampling period (for example, 2 seconds), and the body temperature is measured by a predetermined method based on the sample data. Here, the peak hold method is used for the measurement. In the peak hold method, the temperature is periodically sampled and the highest value among the sampled temperatures is held. The temperature measurement unit 1 ends the measurement when the rate of increase of the sample data becomes a predetermined value, for example, 0.019 ° C./16 seconds or less, and sets the highest value obtained at that time as a measurement value, and the CPU 41 It is stored in the RAM 42. Further, the sample data used for measurement does not use the measurement value from the sensor unit 32a as it is, but as the sample data at a certain point in time, calculates the arithmetic average of the data itself and the three sample data before and after the data itself, Used as sample data.
By doing so, it is possible to perform measurement more accurately while suppressing variation between samplings. When one measurement is completed in this way, the measurement value is read from the RAM 42 by the display control unit 6 and displayed on the display unit 7.

<Contents of Data Processing> In the data processing mode, the first day of menstruation is determined using the accumulated measured values. If the first day of menstruation is updated from the previous date, the first day of menstruation is updated from the first day of menstruation before the update. For the latest menstrual cycle up to the day before the first day, calculate the average high-temperature phase and average low-temperature phase, and calculate the average menstrual cycle and reference body temperature using the data of the past menstrual cycle accumulated until then. I do. Furthermore, the day when the measurement was performed (hereinafter referred to as today)
The ovulation day is detected by determining whether the phase is a high temperature phase or a low temperature phase, and the average body temperature is calculated. Finally, using these data, the next menstrual day, the next ovulation day, and the expected birth date are predicted.

FIG. 4 is a diagram showing an example of a menstrual cycle. The numbers with circles represent the first day of menstruation in each menstrual cycle, and the symbols a to h between them represent menstrual cycles, respectively. Each menstrual cycle includes low-temperature phases H to N starting from the first day of menstruation and high-temperature phases starting from the ovulation day ◎. This woman's thermometer predicts (estimates) the next ovulation date and menstrual date with high accuracy when in a certain menstrual cycle, and predicts (estimates) the expected date of childbirth if it is determined to be pregnant from the measurement results. I do. In addition, various data processing will be described with reference to FIG.
It is assumed that the measurement is started from the middle of the menstrual cycle a in FIG. The contents of the processing are as follows.

(1) Calculation Timing FIG. 5 is a flowchart showing the entire processing. The arithmetic processing shown in FIG. 5 shifts to the data processing mode when the power switch is turned off or five hours after the wake-up alarm setting time has elapsed. It is performed once a day. After the second time, the process ends without performing anything. The initial value of the wake-up time is
It is assumed that it is set to exactly 6:00 am next,
The processing in each step will be described in more detail.

(2) Judgment of the first day of menstruation If the input of the menstruation memo has continued for a predetermined number of days or more, for example, three days or more, the first day of the input of the menstruation memo is judged to be the first day of the menstruation. If the number of days is less than a predetermined number of days, for example, less than three days, it is determined that the menstruation is incorrect. -If there is no physiological note and the low-temperature phase is started, the start date of the low-temperature phase is the first day of menstruation. However, if a menstrual note is entered before the high temperature phase is started, the first day of menstruation will be corrected.

(3) Average menstrual cycle (not shown) In FIG.
Becomes the menstrual cycle. That is, the period from the first day of menstruation to the day before the first day of next menstruation is a one-month menstrual cycle. -The average menstrual cycle is calculated after the first day of menstruation is determined, and the calculation result is retained until the next day of the first menstruation is determined. For example, when in the menstrual cycle g of FIG. 4, the average menstrual cycle is calculated after the first day of the menstruation of the cycle g is determined, and is held until immediately before the first day of the menstruation of the next cycle. The average menstrual cycle is obtained by averaging predetermined (four times) menstrual cycles obtained by removing the longest cycle and the shortest cycle from the most recent (six) menstrual cycles. -If there is an effective menstrual cycle (described later) for a predetermined number (three times) of the predetermined (four) menstrual cycles to be averaged, the calculated average menstrual cycle is valid. -If data for a predetermined period, for example, six periods, has not been obtained since the start of measurement, as a provisional measure, a predetermined number of times,
For example, if there are three or more effective menstrual cycles, the average is taken as the average menstrual cycle. For example, in the section e of FIG.
Average menstrual cycle = (b + c + d) / 3. However,
b, c, and d are effective menstrual cycles.

Similarly, in the section f, the average menstrual cycle =
(B + c + d + e) / 4. Where b, c, d,
e is the effective menstrual cycle.

In the section g, the average of the effective menstrual cycles for a predetermined number of times (three times) excluding the longest is defined as the average menstrual cycle. The menstrual cycle is valid for a predetermined number of days, for example, 21 days or more and 42 days or less. The average menstrual cycle is effective if the longest cycle and the shortest cycle in the menstrual cycle (maximum 4 cycles) used for calculating the average menstrual cycle satisfy the relationship of (longest cycle <shortest cycle × 2).

For example, in the sections a, b, c and d, an average menstrual cycle cannot be obtained. Further, a predetermined number of effective menstrual cycles, for example, 3
If there are not more than one, or if there is a predetermined number of valid ones, for example, three or more (the longest cycle <shortest cycle x 2) is not satisfied, or if the average menstrual cycle is not valid as a result of calculation, the average It is assumed that no data exists.

As described above, the average menstrual cycle is the average of the effective menstrual cycles of at least a predetermined number (three times) of the most recent (six) times of the menstrual cycle excluding the maximum and the minimum.

(4) Average high-temperature phase period (not shown) In FIG. 4, the symbol ~ indicates the first day of menstruation, は indicates the ovulation day (determined by detection of the ovulation day described later), and the sections A to G indicate the high-temperature phase period (the ovulation day). From the next day to the day before the first day of menstruation), sections b to h
Is the menstrual cycle. -The average high temperature phase period is calculated after the first day of menstruation is determined, and the calculation result is held until the first day of the next menstruation is determined. The average high-temperature phase period is obtained by averaging predetermined high-temperature phase periods, for example, four times, excluding the longest period and the shortest period from the high-temperature phase periods for the last predetermined number, for example, six times. The calculated average high-temperature phase period is effective if there are effective high-temperature phase periods (described later) for a predetermined number, for example, three or more, of the predetermined number of high-temperature phase periods to be averaged, for example, four times. -If data for a predetermined number of times, for example, six times, has not been obtained since the start of the measurement, the average high-temperature phase period is set to (A + B + C) / 3 in the section e as a provisional measure. Here, A, B, and C are effective high-temperature phase periods.

Similarly, in the section f, the average high-temperature phase period = (A + B + C + D) / 4. However, A, B,
C and D are effective high temperature phase periods.

In the section g, the average of the high-temperature phase periods of three or more effective predetermined times excluding the longest, for example, three times, is defined as the average high-temperature phase period. -The high-temperature phase period is valid for a predetermined number of days, for example, 12 days or more and 16 days or less. Non-effective high temperature phase periods are excluded from the calculation.

For example, in the sections a, b, c, d, the average high temperature phase period cannot be obtained. In addition, if the effective high-temperature phase period is not equal to or more than a predetermined number (three) in the most recent menstrual cycle, for example, the 6-month menstrual cycle, or if the calculation indicates that the average high-temperature phase period is not valid, there is no average high-temperature phase period data. Shall be.

(5) Average low-temperature phase period (not shown) In FIG. 4, the symbol ~ indicates the first day of menstruation, ◎ indicates the ovulation day (determined by detection of ovulation day described later), and the sections H to N indicate the low-temperature phase period (from the first day of menstruation). Until the day of ovulation), sections b to h are menstrual cycles. -The average low-temperature phase period is calculated after the first day of menstruation is determined, and the calculation result is held until the next day of the first menstruation is determined. The average low-temperature phase period is obtained by averaging a predetermined number of low-temperature phase periods, for example, four times, excluding the longest period and the shortest period from the low-temperature phase period for the last predetermined number, for example, six times. The calculated average low-temperature phase period is valid if there is an effective low-temperature phase period (to be described later) for a predetermined number of times, for example, three or more, out of a predetermined number of low-temperature phase periods, for example, four times. If data for a predetermined number of times, for example, six times, has not been obtained since the start of the measurement, the average low-temperature phase period is set to (H + I + J) / 3 in the interval e as a provisional measure. Here, H, I, and J are effective high-temperature phase periods.

Similarly, in the section f, the average high-temperature phase period = (H + I + J + K) / 4. Where H, I,
J and K are effective low-temperature phase periods.

In the section g, the average of the low-temperature phase periods for three or more effective predetermined times excluding the longest, for example, three times, is set as the average low-temperature phase period. -The low-temperature phase period is valid for a predetermined number of days, for example, 5 days or more and 30 days or less. Non-effective cold phase periods are excluded from the calculation.

For example, in the sections a, b, c and d, an average low-temperature phase period cannot be obtained. Also, recently prescribed menstrual cycle,
For example, a predetermined number of effective low-temperature phase periods (3
If not, or if the calculation results show that the average low-temperature phase period is not valid, there is no average low-temperature phase period data.

(6) Schedule of next menstrual day (display) In FIG. 4, symbol 符号 indicates the first day of menstrual memo input, and sections a to g indicate the menstrual cycle. -The next menstrual date is calculated after the average menstrual cycle and the average high-temperature phase period are completed after a predetermined number of times, for example, the fourth menstrual period first day is determined. In the sections a to d in FIG. 4, the next scheduled menstrual date is not obtained, so that there is no data of the next menstrual day in that case. The next menstrual date 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).
I do.・ If the day of this calculation is the low-temperature phase (determined by the phase determination described later) Next menstrual date = recent first menstrual cycle + average menstrual cycle-possible period-recent menstrual cycle + average menstrual cycle + possible period I do. However, the possible period is equivalent to 1.5 σ as the normal distribution of the menstrual cycle used for calculating the average menstrual cycle.
Let it be 2. The possible period is rounded to the first decimal place.・ If the day of this calculation is in the high temperature phase (determined by the phase determination described later) Next menstrual date = recent ovulation date + average high temperature phase period-possible period-recent ovulation date + average high temperature phase period + possible Period. However, the possible period is assumed to be 1.5σ equivalent / 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 menstrual date estimated in this way is displayed, the display is controlled as follows according to the conditions of the display day. If the display date is not included in the next period, the calculated next period is displayed as it is. If the display day is within the calculated next menstrual period, and if it is a predetermined number of days before the last day of the period, for example, three days before, the displayed period is from the date of the display day to the next menstrual day The last day of the period. That is, on the day of display
The first day of menstruation + the average menstrual cycle + possible period, or the date on the display day to the latest ovulation date + the average high-temperature phase period + possible period. -If the display day is the last day of the next menstrual day minus three days or more, the display is from the date of the display day to the date of the display day + three days until the first day of the menstruation. As a result of the calculation, when the next menstrual day extends over a predetermined number of days, for example, a period of eight days or more, the display is “−−month−−day −−− month−−day”.・ The day of display is the high temperature phase, the number of days from the ovulation day is the prescribed number of days,
For example, in the case of 17 days or more, the display is “−−month−−day to −−−
Month-day ". -When the average menstrual cycle or the average high-temperature phase period is not determined, the display is "--month--day---month--day".

(7) Reference body temperature (not shown) In FIG. 4, the symbol ~ is the first day of menstruation, は is the day of ovulation, sections A to G are the high temperature phase period, sections H to N are the low temperature phase period, and sections b to h are Menstrual cycle. The reference body temperature is calculated after the first day of menstruation is determined, and is maintained until the next first day of menstruation is determined. The reference body temperature is calculated as: reference body temperature = (average high-temperature phase body temperature for a predetermined number of past times (for example, three times) + average low-temperature phase body temperature for a predetermined number of past times (for example, three times)) / 2. However, the high temperature phase average body temperature and the low temperature phase average body temperature are obtained from the below-mentioned average body temperature.

For example, the reference body temperature on the first day of menstruation is as follows: reference body temperature = ((average body temperature in section A + average body temperature in section B + average body temperature in section C) / 3 + (average body temperature in section H + average body temperature in section I + Average body temperature in section J) / 3) / 2.

On the first day of menstruation, the reference body temperature is not updated.

On the first day of menstruation, reference body temperature = (average body temperature in section A + average body temperature in section H) / 2 On the first day of menstruation, reference body temperature = ((average body temperature in section A + average body temperature in section B) / 2
+ (Average body temperature in section H + average body temperature in section I) / 2) / 2. -The reference body temperature in the section a to b is the reference body temperature = 36.5.
Pregiven as ° C.

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

(9) Phase determination (not displayed) The phase on the day of measurement is determined.・ If body temperature on the day ≥ reference body temperature, hyperthermia is considered.・ If body temperature on the day <reference body temperature, hypothermia is assumed. The phase determination is made every predetermined day, for example, every day after the low temperature phase is first confirmed from the start of recording. -If the hypothermia continues for a predetermined number of days, for example, three consecutive days on the day, the low-temperature phase is started a predetermined number of days from the day, for example, two days. Alternatively, when the first day of menstruation is determined, the low-temperature phase starts from the day of menstruation. -If the hyperthermia continues for a predetermined number of days, for example, three consecutive days, on the day, the high-temperature phase is started for a predetermined number of days, for example, two days from the day. However, if there is a fever memo input within a predetermined number of consecutive days, for example, within three days, or if the body temperature is 37.5 ° C. or higher, the measurement result is excluded from the calculation.

(10) Ovulation day detection (not displayed)-The ovulation day is calculated after the start date of the high temperature phase is updated in the phase determination. -The ovulation day is the last day of the low-temperature phase, so it can be obtained by the following formula after the phase determination.

Ovulation date = high-temperature phase start date-1 (11) Schedule of next ovulation day (display) The next ovulation date is a predetermined number of times, for example, after the first menstrual period is determined, the average menstrual cycle and the average low-temperature phase period Calculate (estimate) after the calculation is completed. In addition, since calculation cannot be performed in the sections a to d, “−−month−−day −−− month−−day” is used.・ The next ovulation day is a predetermined period, for example, a period of 3 to 7 days (×
X month xx day to xx month xx day).・ If the day is the low temperature phase, the next ovulation date = recent first period of menstruation + average low temperature phase period-possible period-recent first period of menstruation + average low temperature phase period + possible period. However, the possible period is assumed to be 1.5σ equivalent / 2, where 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, the next ovulation date = recent ovulation date + average menstrual cycle-possible period ~
Recent ovulation date + average menstrual cycle + possible period. However, the possible period is equivalent to 1.5 σ as the normal distribution of the menstrual cycle used for calculating the average menstrual cycle.
Let it be 2. The possible period is rounded to the first decimal place.

When the next ovulation day estimated in this way is displayed, the display is controlled as follows according to the conditions of the display day. -If the display day is not included in the period of the next ovulation day, the calculated next ovulation day is displayed as it is.・ If the current day is within the calculated next ovulation day and the last day of the period is a predetermined day before, for example, 3 days before, the displayed period is from the date of the display to the next ovulation day The last day. That is, the date of the display to the latest first day of menstruation + the average low-temperature phase period + the possible period, or the date of the display to the latest ovulation date + the average menstrual cycle + the possible period. -If the display day is the last day of the next ovulation day-3 days or later, the display is from the display day date to the display day date + until the ovulation day.
3 days. As a result of the calculation, if the next ovulation day is a predetermined number of days, for example, 8 days or more, the display is “−−month−−day −−− month−−day”. -If the day is the high-temperature phase and the number of days since ovulation is a predetermined number of days, for example, 17 days or more, the display is "-------------------------------------------------------------------
Day ”. -When the average menstrual cycle or the average low-temperature phase period is not determined, the display is "--month--day---month--day".

(12) Prediction of expected birth date (display) If the number of days from the last ovulation day exceeds a predetermined number of days, for example, 20 days, and the day (the latest measured body temperature) is a high body temperature, it is estimated by the following equation.

Expected birth date = ovulation date + 265 days ・ If the expected birth date is not obtained, the display is “−”
−month−−day to −−month−−day ”.

(13) Post-processing of missing data (forgetting) of measured body temperature The basal body temperature should be measured every day in principle, but if data is missing due to forgetting to measure, etc., the internal data As calculated from the measured body temperature before and after the missing day. However, it does not display missing data,
The body temperature display on the missing day is “−−−−− ° C.”. The missing data is compensated so that the measured value immediately before the missing value and the measured value immediately after the missing value are linearly interpolated. That is, the following example is obtained. When the measured temperature data is missing for one day (day N), if the measured value on day N-1 is a and the measured value on day N + 1 is b, date | N-1 day | N day | N + 1 day body temperature | a | a + (ba) / 2 | b ・ If 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 days Body temperature | a | a + (ba) / 3 | a + 2 (ba) / 3 | b ・ Similarly, when the measurement temperature data is lost for m days, the body temperature on the day before the loss is a and the body temperature after the loss is a As b, the body temperature on the nth day of the missing = a + n (ba) / (m + 1) The number of consecutive days m of the measured body temperature missing data is a predetermined number of days, for example, 8
Allow until the day. If there is a loss exceeding the predetermined number of days, for example, eight days, the body temperature data is invalidated by going back to the most recent menstrual day. When the effective data of the measured body temperature is equal to or more 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. If the ratio is less than the predetermined ratio, for example, less than 50%, the data in the menstrual cycle is invalidated.

<Procedure of Data Processing> The contents of the processing have been described for each item. The data processing procedure will be described as a series of processing with reference to FIGS. FIG. 5 is a flowchart showing the flow of the entire process.
This is realized by the PU 41 executing a program stored in the ROM 43. Hereinafter, the contents of the processing will be described with reference to a flowchart. 6 to 9 are flowcharts showing a part of the contents of each of the above-described processes, and thus will be described only briefly.

In FIG. 5, it is first determined whether the body temperature measurement of the day has already been completed (step S501). If so, the process ends. If not, first, the missing data is interpolated (step S501). That is, if a predetermined number of days, for example, 8 days or more are missing, the data after the first day of the latest menstruation is invalidated, and if the number of days is less than the predetermined number of days, for example, 7 days or less, the data of the mth day missing n days is replaced by (a + n ( b-
a) / (m + 1)). This is as described in the above item (13).

Next, the first day of menstruation is determined (step S5).
03). The details are as described in item (2) above, but are shown again in FIG. That is, if the input of the menstrual memo continues for a predetermined day or more, for example, three days or more, the first day, that is, the first day of the period, for example, two days before the current day, is updated (step S803). Step S51
When the start date of the low-temperature phase is updated at 09, step S50
3, the first day of menstruation is updated with the low-temperature phase start date (step S808). If the first day of menstruation is updated in step S808, the first day of menstruation is updated with the date on which the menstrual memo was input before the high temperature phase is reached (step S808).
806). The first day of menstruation is updated using any of these three as a trigger.

Next, if the last menstrual cycle is determined,
That is, if the process is the first process after the new first day of menstruation is confirmed, and the data of the immediately preceding menstrual cycle is valid, the average menstrual cycle is calculated (step S506), the average high temperature phase period and the average low temperature phase period (Step S5)
07), the reference body temperature is calculated (step S508).
These three values are calculated in the manner described in the items (3) to (5) and (7) described above.

Steps S506-S508 are processes performed once in one menstrual cycle. On the other hand, steps S509-S514 are executed every time the body temperature is measured every day.

First, phase determination and ovulation date detection are performed (step S510). The details are as described in the above items (9) and (10), but are shown again in FIG. That is, in principle, for a predetermined period, for example, 3
If it is hypothermia or hyperthermia for consecutive days, the first day is set as the start date of the low-temperature phase or high-temperature phase, respectively (steps S1103, S1106). However, if the first day of menstruation is updated on that day, even if it is not hypothermia for three consecutive days, for example, the updated first day of menstruation is set as the start date of the low-temperature phase (steps S1108 and S1109). When the temperature exceeds a predetermined temperature or when a heat generation memo is input, the measured value on that day is not used. The day before the high temperature phase start date is set as the ovulation day in the menstrual cycle (step S1107).

When the phase is determined in step S509, it is determined in step S510 that the low-temperature phase start date is updated today and the first day of menstruation is not updated. If the result is affirmative, the first day of menstruation needs to be updated with the low-temperature phase start date.
Returning to 503, the first day of menstruation is updated again. Accordingly, the first day of menstruation is newly determined, and the data processing relating to the immediately preceding menstrual cycle is performed in steps S504 to S508.
Will be performed.

Thereafter, the average body temperature calculation (step S5)
11), calculation (estimation) of next menstrual day prediction (step S51)
2), Next ovulation day prediction (estimation) calculation (step S51)
3), Prediction of birth expected date (estimation) calculation (step S51)
4) are sequentially performed, and the processing in the data processing mode is completed.

The average body temperature is calculated as described in the item (8).
When the change of the high-temperature phase and the low-temperature phase is confirmed, the average of the body temperature from a predetermined date from the start date of the immediately preceding phase, for example, from the third day to a predetermined day before the start date of the current phase, for example, three days before is obtained. .

The next menstrual day is predicted (estimated) by adding the average high-temperature phase period based on the last ovulation day if the current high-temperature phase is as shown in FIG. ) (Step S1305). If it is the current low-temperature phase, the average menstrual cycle is added based on the last day of the last menstruation, and prediction (estimation) is performed with the variation centered on that day (step S1303). This is as described in the items (6), (11), and (12).

As shown in FIG. 8B, the next ovulation day is predicted (estimated) by adding an average menstrual cycle based on the last ovulation day in the case of the current high-temperature phase and adding a variation around that day. (Step S1404). If it is the current low-temperature phase, the average low-temperature phase period is added based on the first day of the last menstruation, and the prediction is made with the variation centered on that day (step S1406).

The expected birth date is, as shown in FIG. 9, a predetermined day or more after the last ovulation day, for example, 20 days or more, and in the case of a high-temperature phase, the birth date is 265 days after the last ovulation day. The date is obtained (step S1503).

The measured body temperature and the values calculated as described above are all stored in the RAM 421 and stored for 240 days. That is, for example, about 6 to 10 cycles are stored as long as the value is calculated for each cycle of the menstrual cycle, such as a menstrual cycle, a high-temperature phase, a low-temperature phase, and an average body temperature. Therefore, sufficient data can be stored in order to calculate a value obtained based on data in many previous menstrual cycles, such as an average high-temperature phase period and an average low-temperature phase period.

The first day of menstruation, the average menstrual cycle, the ovulation day, the average high-temperature phase cycle, and the average low-temperature phase cycle obtained from the measured basal body temperature and physiological items such as physiological notes and fever notes by the above-described configuration and processing procedure. Based on the physiological cycle, the next menstrual day or the next ovulation day is predicted according to the current phase (low temperature phase or high temperature phase). At this time, the first day of menstruation is determined not only based on the input of the menstrual note but also based on the start date of the low temperature phase, so that the first day of the menstrual period can be accurately determined even without input of the menstrual note. For this reason, it is possible to more accurately predict the period of menstruation and ovulation.

Furthermore, since the first day is determined to be the first day of the high-temperature phase for the first time in the case of hyperthermia for three consecutive days, the determination that the last day of the low-temperature phase is the ovulation day can be performed with high accuracy. In addition, as the accuracy of the start date of the high-temperature phase increases, the accuracy of data processing using the high-temperature phase cycle or corresponding to the current phase increases.

Further, since the missing basal body temperature data is estimated so as to linearly interpolate the values measured before and after the missing period, the missing period includes the boundary between the high temperature phase and the low temperature phase. Even so, the phase boundary can be estimated so that the maximum value of the error is minimized.

Further, when using various physiological cycles obtained from the basal body temperature data, in order to set conditions for valid values and to use only those values that conform to the conditions,
Various values can be calculated using only reliable values.

[0065]

As described above, the woman's thermometer according to the present invention determines that the first day is the first day of menstruation when the physiological memo is continuously input for a predetermined number of days. Therefore, the accuracy of the determination can be improved. Further, as the criterion, the first day when the input of the physiological memo continues for a predetermined number of days,
Since the start date of the low-temperature phase, even if the start date of the low-temperature phase is determined to be the first day of menstruation, if there is a physiological memo input until the high-temperature phase, on that day, etc., there are multiple criteria,
Judgment can be made only from basal body temperature, or from physiological memos alone. For this reason, even if there is an input omission, the accuracy of the determination is not lost.

As described above, the gynecological thermometer according to the present invention is based on the basal body temperature and the inputted physiological data.
If the low-temperature phase, based on the first day of the last menstruation, around the date that the average hypothermic period was added, the range of the possible period of variation in the average hypothermic period is estimated as the ovulation day,
In the case of the high-temperature phase, a range in which a variation in the average menstrual cycle is possible as a possible period is estimated as the ovulation day, centering on the date obtained by adding the average menstrual cycle, based on the last ovulation day. In this way, as a reference date for estimation, a date as low as possible on the last day of menstruation is used according to the phase on the day of the measurement, and the date as new as possible is used, so that the estimation accuracy of the next scheduled ovulation date can be improved.
