Description

  The present invention relates to a female thermometer and a menstrual cycle prediction program used by women for measurement of basal body temperature and prediction of menstrual cycle.

A woman's basal body temperature periodically has two phases, a high temperature phase and a low temperature phase, and a female thermometer is used to measure the basal body temperature. By recording a basal body temperature daily with a female thermometer and creating a trend graph, the measurer can know the cycle of the high temperature phase and the low temperature phase. Digital female thermometers are also used to accurately record basal body temperature trends. In addition to body temperature measurement, some digital female thermometers have the function of recording the measured body temperature and creating a trend graph, and predicting the next menstrual day, the next ovulation day, etc. (for example, patents) Reference 1 etc.).

<Functions of female thermometer>
FIG. 3 is a state transition diagram showing transitions of function modes for performing various functions of the lady's thermometer, such as body temperature measurement, memo input, and estimation result calculation and display. The female thermometer of this embodiment operates in the mode shown in FIG. Note that the key names and modes described here are examples, and for example, the predicted ovulation date display mode or the expected birth date display mode may be used to shift from the direct measurement mode by pressing a specific key. .
(1) Stop mode When the power key 300 is turned off or a predetermined time has elapsed after the power is turned on, the stop mode is entered. Even when the lady's thermometer is in a power-off state, the power supply of the entire circuit is not cut off, and the input unit 44 and the CPU 41 are used to perform the functions in the alarm timer and data processing mode. Electric power is supplied to the portions excluding the display unit 7, the body temperature measurement unit 1, the sensor unit 32a, and the like, although they are weak. In the stop mode, power is supplied only to a portion necessary for restarting in this way.
(2) Measurement mode When the power key 300 is turned on or reset by the cancel key 307, the measurement mode is entered. In this measurement mode, the current day measurement value indicated by the clock 8 is displayed in the initial state. Further, by operating the + key or the-key of the body temperature display / movement key 305, 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, and the body temperature measurement is started when the measurement start condition is met.
(3) Memo mode In the measurement mode, when the memo key 302 constituting the key panel 34 as the input unit 44 is pressed, the mode shifts to the memo mode. When entering this mode, you can enter notes related to multiple items (six items in this example) such as menstrual notes, fever notes, cage notes, menstrual pain notes, and intercourse notes for the date set in the measurement mode. . Each time the memo key 302 is pressed, items to be set are shifted sequentially. At that time, the memo display bar 33b corresponding to the item currently set is displayed blinking. The operator can know the item to be set by looking at the blinking display. When the enter key 304 is pressed for each item, the fact that the memo item has been set is stored, the memo display bar 33b corresponding to the item is displayed, and the measurement mode is returned to. Also, no item is confirmed, and the measurement mode is returned to when the sixth memo key 302 is pressed. The memo item set in this way is read for each date specified in the measurement mode, and a memo display bar 33b corresponding to the set item is displayed.
(4) Predicted physiological date display mode When the function key 301 is pressed in the measurement mode, the mode changes to the predicted physiological date display mode. When entering this mode, the next menstruation date already calculated and stored is displayed. In addition, by pressing the + key 305 in the predicted physiological date display mode, the physiological date of the next menstrual cycle is displayed. Each time the + key 305 is pressed, the menstruation date of the future menstrual cycle that is one cycle apart is displayed. On the other hand, every time the -key 305 is pressed, the menstrual days of the next menstrual cycle are displayed one cycle at a time. However, it does not go back before the next menstruation day. When the cancel key 307 is pressed, the measurement mode is restored. This procedure is described in detail in FIG. 8A.
(5) Predicted ovulation day display mode When the function key 301 is pressed in the predicted menstrual day display mode, the mode changes to the predicted ovulation day display mode. When this mode is entered, the next ovulation date already calculated and stored is displayed. By pressing the + key 305 in the predicted ovulation day display mode, the ovulation day of the next menstrual cycle is displayed. Each time the + key 305 is pressed, the ovulation date of the future menstrual cycle that is one cycle apart is displayed. Conversely, each time the − key 305 is pressed, the ovulation date of the future menstrual cycle is displayed one cycle at a time. However, it does not go back before the next ovulation date. When the cancel key 307 is pressed, the measurement mode is restored. This procedure is described in detail in FIG. 8B.
(6) Expected delivery date display mode When the function key 301 is pressed in the predicted ovulation date display mode, the expected delivery date calculated and stored is displayed. When the function key 301 or the cancel key 307 is pressed in the scheduled delivery date display mode, the mode returns to the measurement mode.
(7) Data processing mode In this mode, the data processing shown in FIGS. This mode shifts when the power key 300 is turned off or after a predetermined time, for example, 5 hours elapses from the set time of the alarm 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 In the data processing mode, various data including the next ovulation date and the next menstruation date are calculated and stored.

  The mode of the female thermometer of this embodiment is the above seven modes. In each mode, when the cancel key 307 is pressed, 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 307 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.

<Body temperature measurement sequence>
In the measurement mode, when the measurement subject inserts the sensor unit 32a at the tip of the probe 32 into the mouth and starts measuring the body temperature, the body temperature measurement unit 1 follows a predetermined procedure based on the temperature input from the sensor unit 32a. Start measuring body temperature. Then, the measurement value obtained when the measurement is completed is stored in the RAM 42. For this purpose, the body temperature measurement unit 1 samples the temperature data detected by the sensor unit 32a every predetermined time. When the measured value exceeds a certain threshold value and the temperature increase rate becomes equal to or higher than a predetermined value, the measurement is started from that point. In this embodiment, for example, when the sample data exceeds 30 ° C. and the rate of temperature increase reaches a predetermined value, for example, 0.25 ° C./4 seconds or more, body temperature measurement is started from that point.

  When the measurement is started, the temperature detected by the sensor unit 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 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 in 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 the measured value on the measurement date. Is stored in the RAM 42 by the CPU 41. Alternatively, the sample data used for the measurement does not use the measurement value from the sensor unit 32a as it is, and as the sample data at a certain time point, obtain the arithmetic addition average of the three sample data including the data itself and the front and back thereof, May be stored as measured values. By doing so, it is possible to perform measurement more accurately while suppressing variations in sampling. When one measurement is thus completed, the measured value is stored, and the measured value is read from the RAM 42 by the display control unit 6 and displayed on the display unit 33.

<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. The average high-temperature phase period and average low-temperature phase period are determined for the period. Moreover, the average menstrual cycle and the reference body temperature are calculated using the data about the past menstrual cycle accumulated so far. Further, it is determined whether the day of measurement (hereinafter referred to as today) belongs to the high-temperature phase or the low-temperature phase, the ovulation day is detected, and the average body temperature is calculated. Finally, using these data, the next menstrual date, the next ovulation date, the future menstrual date and ovulation date, and the expected date of birth are calculated.

  FIG. 4 is a diagram illustrating an example of a menstrual cycle. The encircled numbers represent the first menstrual periods 401 to 408 in each menstrual cycle, and the symbols a to h in between indicate the menstrual cycle. The menstrual cycle is a cycle in which the first day of menstruation is the start date and the day before the next menstruation day is the last day. Each menstrual cycle includes a warm phase period H to N from the first day of menstruation to the day before the day of ovulation, and a high temperature phase period A to G from the day of ovulation to the day before the first day of the next menstruation. That is, if the next menstrual date can be predicted, the date obtained by adding the menstrual cycle predicted to the date becomes the next predicted menstrual date. Further, if the next ovulation day can be predicted, the day obtained by adding the predicted physiological cycle to the date becomes the next predicted ovulation day. This female thermometer predicts (estimates) the next ovulation day and menstrual day with high accuracy when in a certain menstrual cycle, and also predicts (estimates) the expected date of delivery if it is determined to be pregnant from the measurement results To do. Furthermore, long-term menstrual cycles such as ovulation days and menstrual days after the next are predicted with high accuracy. Various data processing will be described with reference to FIG. 4. At this time, it is assumed that the measurement starts from the middle of the menstrual cycle a in FIG. The contents of the processing are as follows. Sections A to G are high-temperature phases (from the day after the ovulation day to the day before the first day of menstruation), and sections b to h are menstrual cycles.

(1) Calculation Timing FIG. 5 is a flowchart showing the entire process. The calculation process shown in FIG. 5 is performed when the power key 300 is turned off or after a predetermined time has elapsed since the alarm alarm set time has elapsed (in this example, 5 hours later). The mode is shifted to the data processing mode once a day. After the second time, nothing is performed and the process ends. Next, the process in each step will be described in more detail.

(2) Menstruation first day judgment (S503)
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.

(3) Average menstrual cycle (not shown) (S506)
As can be seen from FIG. 4, the period from the first menstrual period 401 to 408 to the day before the first menstrual period 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. For example, when the measurement date is in the menstrual cycle g in FIG. 4, the average menstrual cycle is calculated after the first period 406 of the cycle g is determined, and the average menstrual cycle calculated at that time is the first cycle 407 of the next cycle. It is held in the average menstrual cycle storage unit 421a until immediately before. When the next menstrual first day 407 is confirmed, the average menstrual cycle is recalculated.
The average menstrual cycle is obtained by averaging the predetermined menstrual cycle (for example, four times) obtained by removing the longest cycle and the shortest cycle from the menstrual cycle of the latest predetermined times (for example, six times). For example, when the first menstrual period 407 that is the first day of the menstrual cycle h is determined, the menstrual cycle g is determined. In that case, the menstrual cycle g including the menstrual cycle g is recalculated by averaging the menstrual cycle of a predetermined number (4 times) excluding the longest cycle and the shortest cycle from the menstrual cycle of a predetermined time (6 times) from the newest one. The
-If there are more than a predetermined number (for example, three times) of effective menstrual cycles (described later) among the predetermined (four times) average menstrual cycles, the calculated average menstrual cycle is valid.
When data for a predetermined period, for example, 6 periods, has not been obtained since the start of measurement, as an interim measure, if there are effective periods for a predetermined number of times, for example, 3 times, the average is set as the average menstrual period. For example, in the interval e in FIG. 4, the average menstrual cycle = (b + c + d) / 3. However, b, c, and d are effective menstrual cycles. Similarly, in the interval f, the average menstrual cycle = (b + c + d + e) / 4. However, b, c, d, and e are effective menstrual cycles. Also, in the interval g, the average of the effective menstrual cycles over a predetermined number of times (for example, four 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 valid 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 (longest cycle <shortest cycle × 2). For example, the average menstrual cycle is not obtained in the sections a, b, c, and d. In addition, even if there is no predetermined number of effective menstrual cycles, for example, 3 or more in the latest predetermined menstrual cycle, for example, 6 menstrual cycles, or even when there are a predetermined number of effective menstrual cycles, for example, 3 or more (longest cycle <shortest cycle × If 2) is not satisfied, or if the average menstrual cycle is not valid as a result of the calculation, there is no data on the average menstrual cycle.
Thus, the average menstrual cycle is an average of effective menstrual cycles for at least a predetermined number (three times) of the menstrual cycle for a predetermined number of times (for example, six times).

(4) Average high-temperature phase period (not shown)
As shown in FIG. 4, the high-temperature phase periods A to G are the period from the day after the ovulation date to the day before the first day of menstruation, and each period is included in the menstrual cycles b to h.
-The average high-temperature phase period is calculated after the first day of menstruation is confirmed, and the calculation result is retained until the next day of menstruation is confirmed.
The average high temperature phase period is obtained by averaging a predetermined number of recent times, for example, six times of the high temperature phase period, excluding the longest period and the shortest period, for example, four high temperature phase periods.
The calculated average high-temperature phase period is valid if there is an effective high-temperature phase period (described later) for a predetermined number of times, for example, four times of the high-temperature phase period to be averaged.
When data for a predetermined number of times, for example, six times has not been obtained since the start of measurement, as a provisional treatment, in the section e, the average high temperature phase period = (A + B + C) / 3. However, 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 that are valid predetermined times except the longest, for example, three or more high-temperature phase periods 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. Ineffective high temperature phase periods are excluded from the calculation. For example, in the sections a, b, c, and d, the average high temperature phase period cannot be obtained. In addition, there is no average high-temperature phase period data when there is no more than a predetermined number (three) of effective high-temperature phase periods in the latest menstrual cycle, for example, the June menstrual cycle, or when the average high-temperature phase period is not valid as a result of calculation. Shall.

(5) Average low-temperature phase period (not shown)
As shown in FIG. 4, the low-temperature phase periods H to N are periods from the first day of menstruation to the date of ovulation, and each period is included in the menstrual cycles b to h.
・ The average low-temperature phase period is calculated after the first day of menstruation is confirmed, and the calculation result is retained until the next day of menstruation is confirmed.
The average low temperature phase period is obtained by averaging a predetermined number of recent times, for example, six times of the low temperature phase period, excluding the longest period and the shortest period, for example, four low temperature phase periods.
The calculated average low-temperature phase period is effective if there are effective low-temperature phase periods (described later) for a predetermined number of times, for example, four times of the low-temperature phase period averaged, for example, three times or more.
-When data for a predetermined number of times, for example, six times has not been obtained since the start of measurement, as a provisional treatment, the average low temperature phase period = (H + I + J) / 3 is set in the section e. However, H, I, and J are effective high temperature phase periods. Similarly, in the interval f, the average high temperature phase period = (H + I + J + K) / 4. However, H, I, J, and K are effective low temperature phase periods. In the section g, the average of the low-temperature phase periods that are valid predetermined times except the longest, for example, three times or more is defined as the average low-temperature phase period.
-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. For example, in the sections a, b, c, and d, the average low-temperature phase period cannot be obtained. 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) Reference body temperature (not shown)
The reference body temperature is calculated after the first menstrual days 401 to 408 are determined, and the calculated value is held until the next menstrual first day is determined.
The reference body temperature is calculated as (high temperature phase average body temperature for the past predetermined times (for example, 3 times) + low temperature phase average body temperature for the 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 described later. For example, the reference body temperature on the first physiological day 404 is ((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. In addition, on the first day of menstruation 401, the reference body temperature is not updated. On the first day of menstruation 402, reference body temperature = (average body temperature in section A + average body temperature in section H) / 2, and on first day of menstruation 403, 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.
A predetermined value, for example, 36.5 ° C., is given as the reference body temperature in the menstrual cycles ab.

(7) 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 determination.
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.
The average body temperature of the low-temperature phase is calculated based on the body temperature up to a predetermined day, for example, 3 days before the start of the high-temperature phase, with the body temperature on the predetermined day, for example, the third day from the start of the low-temperature phase as an initial value.

(8) Phase judgment (not shown)
It is determined whether the measurement day belongs to the high temperature phase period or the low temperature phase period.
・ If the measured body temperature on the day ≧ the reference body temperature, the body temperature is assumed to be high (high temperature phase).
・ If the measured body temperature on the day <the reference body temperature, the hypothermia (low temperature phase).
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 on the day, for example, 3 consecutive days, the high-temperature phase starts from a predetermined number of days, for example 2 days. However, when there is a fever memo input within a predetermined number of consecutive days, for example, within three days, or when the body temperature is equal to or higher than a predetermined value (for example, 37.5 ° C.), the measurement result is excluded from the calculation.

(9) 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.
-Since the ovulation day is the last day of the low temperature phase, after the phase determination, the ovulation date = the high temperature phase start date -1 is obtained.

(10) Missing data of measured body temperature (forgotten) post-processing Basic 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.
When 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, the body temperature on the Nth day is a + (b- a) / 2.
When the measured body temperature data is missing for 2 days (day N, day N + 1), body temperature on day N is a + (ba) / 3, body temperature on day N + 1 is a + 2 * (ba) / 3.
Similarly, when the measured body temperature data is missing for m days, the body temperature on the missing day n is a + n * (ba) / (m + 1), where a is the body temperature on the day before missing and b is the body temperature after missing.
-The number of consecutive days m of measurement temperature missing data is allowed up to a predetermined number of days, for example, 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.

(11) The next menstruation schedule / next menstruation is calculated after the end of the calculation of the average menstrual cycle and the average high-temperature phase period after a predetermined time, for example, the fourth menstrual first day is determined. In the menstrual cycles a to d in FIG. 4, the next menstrual scheduled date is not obtained, and there is no data for the next menstrual date in that case.
The next period is predicted (estimated) as a predetermined period, for example, a period of 3 to 7 days (year / month / day to year / month / day). Alternatively, only the predicted date of the next menstrual first day is displayed, and “year / month / daily” is displayed. The first menstrual day obtained by the prediction calculation is stored in the next menstrual day storage unit 421b of the RAM.
-If the day on which this calculation processing is performed is a low-temperature phase (determined by phase determination described later), the next menstrual day is (Recent menstrual first day + average menstrual cycle-possible period)-(Recent menstrual first day + average menstrual period) 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.
-If the day on which this calculation process is performed is a high-temperature phase (determined by phase determination described later), the next menstrual day is (recent ovulation day + average high-temperature phase period-possible period) to (recent ovulation day + 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 displaying the next menstruation predicted in this way, 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, three days ago, the period displayed will be The last day of the period. That is, the next menstrual date is from the date of display to (recent menstrual first day + average menstrual cycle + possible period) or from the date of display to (recent ovulation date + average high-temperature phase period + possible period).
-If the display day is the specified number of days after the last day of the next menstrual day, for example after 3 days, the period displayed from the date of the display to the date of the display + the predetermined number of days (eg 3 days) And
-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 shows the year, month, and day with hyphens, respectively, "-/-/ ----- /-// “-”. Note that “/” is a year / month, month / day separator, and the order of the year / month / day can be determined according to the user's preference and custom.
-When the display day is a high temperature phase and the number of days from the ovulation day is a predetermined number of days, for example, 17 days or more, the display is "-/-/ ----- /-/-".
・ If the average menstrual cycle or average high-temperature phase period has not been established, the display shall be "-/-/-to-/-/-".

(12) Schedule for next ovulation day (memory and display)
The next ovulation date is calculated (predicted) 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 physiological first day is determined. In addition, since it cannot be calculated in the menstrual cycles a to d, “− // −− / −− to −− / −− / −−” is displayed.
-The next ovulation day is displayed as a predetermined period, for example, a period of 3 to 7 days (year / month / day to year / month / day). Alternatively, only the predicted date of the next ovulation date is displayed, and “year / month / day” is displayed. The next ovulation date obtained by the prediction calculation is stored in the next ovulation date storage unit 421c of the RAM.
-If the day is in the low temperature phase, the next ovulation date shall be (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 in the high temperature phase, the next ovulation date is (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 day, and if it is from the last day of the period to a certain day before, for example, 3 days before, the displayed period will be the period of the next ovulation day from the date of the displayed 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.
When the display day is a predetermined number of days (for example, 3 days) after the last day of the next ovulation day, the display is made from the date of the display day to the date of the display day + a predetermined number of days (for example, 3 days) until the ovulation day.
-As a result of calculation, when the next ovulation day is a predetermined number of days, for example, 8 days or more, the display is "-/-/ ----- /-/-".
-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 "-/-/ ----- /-/-".
・ If the average menstrual cycle or average low-temperature phase period has not been established, the display shall be "-/-/-to-/-/-".

(13) 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 the current day (latest measured body temperature) is a high body temperature, the expected date of birth is estimated by the formula: expected date of birth = ovulation date + 265 days.
・ If the expected date of delivery is not requested, the display shall be "-/-/-to --- /-/-".

<Data processing procedure>
The contents of the processing have been described for each item of the data processing executed in the procedure of FIG. 5, but the data processing procedure will be described as a series of processing with reference to FIGS. FIG. 5 is a flowchart showing the overall flow of processing, which is realized by executing a program stored in the ROM 43 by the CPU 41 in FIG. Hereinafter, the contents of the processing will be described with reference to a flowchart. 6 to 8 are flow charts showing a part of the contents of the above-described processes, so that only a simple touch can be made.

  In FIG. 5, it is first determined whether today's body temperature measurement has already been completed (step S501). If it has been completed, the process ends. If not completed, the missing data is first interpolated (step S502). That is, if there is a missing period of a predetermined number of days, for example, 8 days or more, the data after the first day of the latest menstrual period is invalidated. Interpolation is performed according to the equation b−a) / (m + 1)). This is as described in item (13) above.

  Next, the first day of menstruation is determined (step S503). The details are as described in item (2) above, but are shown again in FIG. That is, if the physiological memorandum input is continued for a predetermined day or more, for example, three days or more, the first day is updated, that is, the date before the predetermined day, for example, two days before that day (step S803). When the start date of the low temperature phase is updated in step S509, the process returns to step S503. In this case, the physiological first day is updated with the start date of the low temperature phase (step S808). In addition, when the first menstrual day is updated in step S808, the first menstrual day is updated with the date when the menstrual memo is input before the high temperature phase is reached (step S806). The first day of menstruation is updated with any of these three as a trigger.

  Next, if the immediately preceding menstrual cycle is confirmed, that is, if this is the first processing after the new menstrual first day is confirmed, and the data of the immediately preceding menstrual cycle is valid, the calculation of the average menstrual cycle ( Step S506), calculation of average high temperature phase period and average low temperature phase period (step S507), and calculation of reference body temperature (step S508) are performed. These three values are calculated in the manner described in the above items (3) to (6). In particular, when the average menstrual cycle is calculated in step S506, the value is stored in the average menstrual cycle storage unit 421a. If it cannot be calculated, a sign indicating that it has not been calculated is stored in the average menstrual cycle storage unit 421a. Steps S506 to S508 are processes performed once in one menstrual cycle.

  In contrast, steps S509 to S514 are executed every time body temperature is measured. First, phase determination and ovulation date detection are performed (step S509). The details are as described in the above items (8) and (9), but are shown again in FIG. That is, in principle, if the body temperature is low or high for a predetermined day, for example, three consecutive days (S1102-YES or S1104-YES), the first day is set as the start date of the low temperature phase or the high temperature phase, respectively (step S1103). , S1106). However, if the first day of menstruation is updated on that day, even if it is not a hypothermic temperature 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). Further, when the temperature exceeds the predetermined temperature or when a heat generation memo is input, the measurement value of the day is not adopted (S1105—YES). Further, the day before the high temperature phase start date is set as the ovulation day in the menstrual cycle (step S1107).

  When the phase determination is performed in step S509, it is determined in step S510 that the low-temperature phase start date is updated as of today (that is, the measurement day) and the physiological first day is not updated. If this result is affirmative, the first day of menstruation needs to be updated with the start date of the low temperature phase, so the process returns to step S503 to update the first menstruation day again. Accordingly, the first day of menstruation is newly determined, and data processing related to the menstrual cycle immediately before is performed in steps S504 to S508.

  If the determination is negative in step S510, the average body temperature calculation (step S511), the next menstrual day prediction (estimation) calculation (step S512), the next ovulation day prediction (estimation) calculation (step S513), the expected delivery date prediction (Estimation) Calculation (step S514) is sequentially performed, and the process in the data processing mode is terminated.

  Here, as explained in item (7), the average body temperature is determined on the predetermined day from the start date of the immediately preceding phase, for example, from the third day, at the time when the change between the high temperature phase and the low temperature phase is confirmed. The average body temperature up to a predetermined day before the start date, for example, up to 3 days before is obtained.

  Further, as shown in FIG. 8 (A), the next menstrual day is predicted (estimated) by adding an average high temperature phase period based on the last ovulation day in the case of the current high temperature phase, and taking into account variations around that day. (Step S1305). In the case of the current low-temperature phase, an average menstrual cycle is added with reference to the last first physiological period, and prediction (estimation) is performed by taking into account variations around that day (step S1303). This is as described in item (11). The obtained next menstrual date is stored in the next menstrual date storage unit 421b. If it cannot be calculated, a sign indicating that it has not been calculated is stored in the next menstruation date storage unit 421b.

  As shown in FIG. 8 (B), the next ovulation day is predicted (estimated) by adding an average menstrual cycle based on the last ovulation day in the current high-temperature phase, and taking into account variations around that day (step). S1404). If it is the current low-temperature phase, the average low-temperature phase period is added with reference to the first physiological first day, and the prediction is performed by taking into account variations around that day (step S1406). The obtained next ovulation date is stored in the next ovulation date storage unit 421c. If it cannot be calculated, a code indicating that it has not been calculated is stored in the next ovulation date storage unit 421c.

  The expected date of birth is determined as the expected date of birth on the 265th day from the last ovulation date when 20 days or more have passed since the last ovulation date and, for example, in the high temperature phase. If the conditions are not satisfied and the expected date of delivery is not obtained, information indicating that is stored instead of the expected date of delivery.

<Predicted date display processing>
Next, the predicted date display process will be described with reference to FIGS. 9A to 11. The prediction display process is a process executed in the predicted menstrual date display mode, the predicted ovulation day display mode, and the expected delivery date display mode of FIG.

  Hereinafter, prediction and display of menstruation days and ovulation dates from the next time will be described based on flowcharts.

  FIG. 9A shows a predicted date display for the next menstrual day and a forecast processing flow for the subsequent menstrual date. First, the next menstruation date display is selected, and it is determined whether the menstrual cycle average days and the next menstruation date have been obtained (step S902). If the menstrual cycle average number of days and the next menstrual day have been obtained (step S902-Y), the next menstrual date is displayed, and the counter N for counting the menstrual days after the next is cleared to 0 (step S903), and the next menstrual date Is displayed (step S904).

  If the menstrual cycle average number of days has not been finalized or if the next menstrual day has not been predicted (step S902-N), the menstruation date cannot be calculated from the next time, so the next menstruation date is not predicted and the display unit 33 indicates that the prediction is impossible. For example, “-/-/-” is displayed (step S913).

  Thereafter, when the cancel key 307 is pressed (step S913-1-Y), the prediction date display of the next menstrual day and the menstrual day prediction processing flow after the next are terminated. When the function key 301 is pressed without pressing the cancel key 307 (step S913-2-Y), the next ovulation day prediction date display and the subsequent ovulation day prediction processing flow are performed.

  Next, when the next menstruation date is displayed, when the + key 305 as an operation button is pressed (step S905), the counter N is incremented by 1 (step S906), and the counter N × the number of menstrual cycle average days is calculated. By adding to the menstrual day, the menstrual date is obtained one after another (step S907).

  If it is a PC or the like, clicking the + key display on the screen with a mouse or the like displays the calendar for the next month and increments the counter N by +1.

  Next, the menstruation date after the obtained next time is displayed on the display unit 33 (step S908). An example of this is shown in FIG. In this display example 1001, the display of the menstrual date indicates a certain date rather than a range. This date may be a predicted date or may be the first day of a range that may have been obtained by taking into account deviations.

  Further, when displaying the predicted menstrual date, a symbol mark 38 indicating that fact is also displayed. -When the key 305 is pressed (step S909-Y), the counter N is set to -1 DOWN (step S910), and the menstrual date one cycle before is displayed. However, the next menstruation date cannot be traced back.

  FIG. 9B is a prediction process flow for displaying the predicted date of the next ovulation date and the next and subsequent ovulation dates. The next ovulation day display is selected, and it is determined whether the average number of menstrual cycle days and the next ovulation date are obtained (step S914). When the menstrual cycle average days and the next ovulation date have been obtained (step S914-Y), the next ovulation date is displayed, and the counter N for counting the ovulation date after the next is cleared to 0 (step S916).

  When the + key 305 as an operation button is pressed (step S918), the counter N is incremented by 1 (step S919), the counter N × the number of menstrual cycle average days is calculated and added to the next ovulation day to obtain the ovulation date one after another. (Step 5920) and displayed on the display unit 33 (Step S921).

  An example of this is shown in FIG. In this display example 1002, the next ovulation date is not a range but a certain date. This date may be a predicted date or may be the first day of a range that may have been obtained by taking into account deviations. Further, when displaying the predicted ovulation date, a symbol mark 39 for displaying that fact is also displayed. If it is a PC or the like, clicking the + key display on the screen with a mouse or the like displays the calendar for the next month and increments the counter N by +1.

  In step S914, if the menstrual cycle average number of days is not finalized or if the next ovulation date cannot be predicted (step S914-N), the ovulation date cannot be calculated from the next time onward, so the prediction of old ovulation from the next time onward is not possible. The display unit 33 displays that the prediction is impossible (step S926). For example, “-/-/-” is displayed. Thereafter, when the cancel key 307 is pressed (step S926-1-Y), the predicted date display of the next ovulation date and the subsequent ovulation date prediction processing flow are terminated. If the function key 301 is pressed without pressing the cancel key 307 (step S926-2-Y), the process proceeds to the predicted display process flow for the expected delivery date.

  Further, when the -key 305 is pressed in step S918 (step S922-Y), the counter N is decreased by -1 (step 5923), it is determined whether N is 0 or more (step S924), and N is 0 or more (step S924). The process proceeds to step S924-Y) and step S920. When N is not 0 (step S924-N), the process proceeds to step 5914-Y.

  If the -key 305 is not pressed in step S922 (step S922-N), the process proceeds to step 5925, and if the cancel key 307 is pressed (step S925-Y), the predicted date display of the next ovulation date and the prediction of the next and subsequent ovulation dates are performed. The processing flow ends. When the cancel key 307 is not pressed (step S925-N) and the function key 301 is pressed (step S927-Y), the next ovulation date prediction date display and the next and subsequent ovulation date prediction processing flow return to step 5914.

  FIG. 9C is a process flow for displaying a scheduled date for a scheduled delivery date. In step S928, it is determined whether or not the expected delivery date is obtained. If a valid delivery date is obtained (step S928-Y), the derived delivery date is displayed (step S929). When the cancel key 307 is pressed (step S930-Y), the predicted date display processing flow for the expected delivery date is ended. If the function key 301 is pressed (step 5931-Y) without pressing the cancel key 307 (step S930-N), the predicted date display processing flow for the expected delivery date is ended. If the function key 301 is not pressed in step S931 (step S931-N), the process returns to step 5929.

  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 if the value is calculated for each cycle of the menstrual cycle, such as a menstrual cycle, a high temperature phase period, a low temperature phase period, and an average body temperature. Therefore, sufficient data can be stored in order to calculate values obtained based on data in many previous menstrual cycles, such as the average high temperature phase period and the average low temperature phase period.

  Physiological factors such as the first day of menstruation, average menstrual cycle, ovulation date, average high-temperature phase cycle, and average low-temperature phase cycle, obtained from the measured basal body temperature and physiological items such as physiology memo and fever memo by the above-described configuration and processing procedure 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, since the determination of the first physiological period is performed not only based on the input of the physiological memo but also based on the start date of the low temperature phase, the first physiological period can be accurately determined even if the physiological memo is not input. For this reason, it becomes possible to predict a menstrual day and an ovulation date with higher accuracy.

  Furthermore, since the first day is determined as the first day of the high temperature phase for the first time when the body temperature is high for three consecutive days, it is possible to determine with high accuracy that the last day of the low temperature phase is the ovulation day. Further, the accuracy of the start date of the high temperature phase increases, so that the accuracy of data processing using the high temperature phase period or the current phase increases.

  Furthermore, in order to estimate the missing basal body temperature data so as to linearly interpolate the values actually measured before and after the missing period, even if the missing period includes the boundary between the high temperature phase and the low temperature phase The phase boundary can be estimated such that the maximum value of the error is minimized.

  In addition, when using physiological cycles obtained from basal body temperature data, only reliable values are used in order to set conditions to be effective values and to use only those values that match them. Thus, various values can be calculated.

  Furthermore, based on the predicted next menstruation date and the next ovulation date, and the average menstrual cycle obtained from the past record, it is possible to predict and display a further menstrual date and ovulation date than the next time.

<Modification>
In FIG. 9A, if either the average menstrual cycle or the next period is not obtained, the process branches to step S913. However, in step S902, it may be determined whether or not the next menstrual day is obtained, and if the next menstrual date is stored, the next menstrual date may be displayed. Then, it is determined whether or not the average menstrual cycle is obtained between step S904 and step S905. If not obtained, the process branches to step S913, and if obtained, the process branches to step S905 to display the subsequent menstrual days. You may make it do. The same applies to the date of ovulation.

  In addition, the present invention can also create an application that predicts and displays data obtained from an existing female thermometer without using the dedicated female thermometer, by transferring or manually inputting data obtained from an existing female thermometer to a PC, PDA, mobile phone, or the like. It is feasible. For example, a computer having the configuration of FIG. 1 excluding body temperature measurement unit 1 and temperature sensor 32a from body temperature data measured by an independent thermometer having body temperature measurement unit 1 and temperature sensor 32a of FIG. 1 via a known interface. To enter. By using the computer to execute the application program that implements the procedure of the present embodiment and processing the input body temperature data, it is possible to predict and calculate the physiological cycle. The buttons used for the operation can be realized by assigning appropriate keys from a computer keyboard or by selecting a control displayed on the screen with a pointer.

  If the procedure shown in FIGS. 5 to 9C is executed by a PC or the like, a calendar for the next month is displayed when the right button display on the screen is clicked with a mouse or the like, and 1 is added to the counter N. An example of this display is shown in FIG. On the screen 1003 of FIG. 10, a left button 1011c and a right button 1011d are displayed on the left and right of the current month 1011e on which the display operation is being performed. Further, the calendar 1011 of the month is displayed, and the predicted menstrual day 1011a and the predicted ovulation date 1011b included in the month are displayed in an easy-to-understand manner with the respective symbols.
