It is possible to accurately detect the fertilization period or the period of risk of fertilization by observing the period within the body.

Next, the electronic circuit built into the body temperature record/display body 1 will be explained in relation to the various operation keys described above.

The details of the electronic circuit are shown in FIG. 3. The electronic circuit records oral body temperature data measured by the thermometer 16 by operating a predetermined operation key, and records the recorded daily body temperature. It has a function of reading out data, outputting it as display information, and displaying it on a single display screen LCD.

To explain in detail below, the TSR is a temperature sensing element (thermistor) for measuring body temperature as described above, and detects a change in body temperature as a change in the resistance value of the thermistor.

A is an analog processing section, which performs analog calculations such as amplification on the voltage signal depending on the resistance value, converts one body temperature into an analog voltage signal, and sends this to the analog/digital conversion section.

The analog/digital conversion unit A/D is the control/calculation unit CPU
The input analog signal is converted into digital data according to the control signal from the controller and output to the control/arithmetic unit CPU.

ROM is a program memory, which is a read-only memory that stores "software" that controls each part of the electrical circuit that makes up the body temperature recording and display device.

Further, the RAM is a data memory, which is a readable and writable memory that stores body temperature data and various data. The control/arithmetic unit (Ill)
gυn1t (central processing unit) has a function of reading the contents of the program memory and controlling each part according to the software (program).

In addition, the input section to the control/calculation section using the various keys mentioned above is shown.

Furthermore, LCD-C is a display control section for controlling and driving the display screen LCD based on control signals and display data (body temperature data) from the control/calculation section CPU.

Display screen LCD is dot matrix L CD
(Dot Matrix) is used.

As shown in Figure 4, this dot matrix LCD has small dots (minimum display unit) arranged vertically and horizontally, and by turning on or off each dot, it is possible to display graphs, numbers, etc. Control unit LCD
eC controls turning on and off of this Dot.

In the present invention, the body temperature measured by the thermometer 16 is displayed numerically on a display screen typified by the above-mentioned dot matrix LCD, and the daily body temperature data is displayed as a curve graph. That is, the home base is equipped with a function that allows the user to know the body temperature at the time of temperature measurement using a numerical display, and allows the user to know the accumulated oral body temperature data in a graph.

A buzzer B is provided to notify the completion of body temperature measurement by the thermometer 16, and its ringing and stopping are controlled by the control/arithmetic unit CPU. The power source for the electronic circuit is a battery built into the display main body l.

When the power key 27 is pressed as described above, the control/calculation section CPU sequentially reads out programs from the program memory ROM and starts controlling each section.

That is, the control/calculation section CPU first initializes each section (makes each section ready for processing), outputs an initial message to the display screen LCD to notify that the operation standby state has been formed, and then , it enters a state of waiting for an input from the key personnel department K. When the temperature measurement key 7 or the graph display key 9 is pressed in the same state, a program is read from the program memory ROM and processing is started according to either of them.

First, I will explain temperature measurement. The user inserts the temperature measuring device 16 under the tongue or armpit and presses the temperature measuring key 7.

When the control/calculation section CPU receives this input from the key human power section, it starts controlling the body temperature measurement.

The thermistor TSR of the thermometer 16 is warmed by body temperature,
The resistance value changes gradually and eventually becomes stable. This change in the resistance value of the thermistor TSR is converted into a voltage signal in the analog processing section A, and analog calculation processing (amplification, biasing, etc.) is performed to simplify subsequent processing, and a voltage signal proportional to temperature is converted into a voltage signal. Analog/digital converter A/D
is constantly supplied. Analog/digital converter A/D
samples the output voltage signal of the analog processing section A at the timing according to the control signal from the control e calculation section CPU, converts it into digital data, and sends it to the control/calculation section CPU.
Output to.

The control/calculation unit CPU reads the input digital data, performs appropriate calculations, converts it into body temperature display data, and then sends it to the display control unit LCD@C.

The display control unit LCD-C displays the body temperature during temperature measurement on the display screen LCD every moment based on the body temperature display data.

Also, when the temperature measurement key 7 is pressed, the control/calculation unit CPU resets the software timer for the temperature measurement timer and starts counting, continues this counting in parallel with the control of body temperature measurement and display, and starts counting after a certain period of time. When the temperature reaches a predetermined value, the body temperature measurement is stopped, and the buzzer B outputs an alarm sound to notify the end of the body temperature measurement. As a result,
``Accurate measurement data is always obtained by the thermometer 16, and this final temperature is finally displayed numerically (for example, 38.3° C.) on the display screen LCD.This final temperature continues to be displayed on the 0 display screen LCD.

After the above-mentioned temperature measurement operation is completed, the control/arithmetic unit CPU waits for input from any one of the temperature measurement key 7, the measurement data recording key 8, and the graph display key 9.

For example, when the temperature measurement key 7 is pressed again, the control/calculation unit CPU displays the display screen LCD and its control unit LCD-C.
Then, reset the software timer (temperature measurement timer) and repeat the temperature measurement control described above.

Next, when the record key 8 is pressed after the above temperature measurement operation is completed, the control/calculation unit CPU displays the current display screen LCD.
After converting the body temperature (final temperature) displayed on the screen into an appropriate form, it is stored in a "predetermined location in the data memory RAM."

This data memory RAM is, for example, 6 as shown in FIG.
It consists of a daily body temperature data storage RAMI having an address of day 0=60gs, a storage RAM2 for the latest recording date, and a RAM3 for storing the number of cycle days.

The above-mentioned "predetermined location in the data memory RAM" is the beginning of the empty area in the body temperature data storage RAMI, and when there is no empty area in the body temperature data storage RAMI (60 days' worth of daily temperature data has already been recorded). ), delete the oldest body temperature data, move all the data one day earlier to create one day's worth of empty space, and then record the new body temperature data here.

That is, as shown in FIG. 5, the oral body temperature data is stored in order from address 1 of the body temperature data storage section RAMI, and when it is stored up to address 60, the data memory becomes full. After this, when storing new body temperature data (60-day oral temperature data), erase the data at address 1, move the data at address 2 to address 1, the data at address 3 to address 2, and so on. After moving the data at address 60 to address 59, new data is stored at address 60. The same applies below.

After the recording process is completed as described above, the control/calculation unit C
The PU displays a message informing the end of recording on the display screen LCD, and waits for input from the temperature measurement key 7 or the graph display key 9.

Next, a case where the graph display key 9 is pressed will be explained.

As mentioned above, the user can view the past recorded daily body temperature data in the form of a curve graph.

In this case, the user first presses the graph display key 9. When the graph display key 9 is pressed, the control e calculation section CPU first outputs a control signal and data to the display control section LCD@C and clears the display screen LCD. do. After that, one piece of latest body temperature data is read from the daily body temperature data storage RAMI of the data memory RAM, and after performing appropriate calculations, it is displayed in the Dot column in the first column at the right end of the display screen LCD, as shown in Fig. 6. The Detl at the corresponding body temperature scale position is turned on. Next, the second newest data is read from the RAMI of the data memory RAM, and the corresponding Dot2 of the third Dot column from the right on the display screen LCD is lit, and the Dots in the second column are the first and second Dot columns. #h Dotl
Light up Dot' so that Dot2 and Dot2 are connected.

As described above, the past daily body temperature data is read out sequentially from RAMI of the data memory RAM, and the display screen L
The graph is displayed on the CD, and the latest 30 days (latest 60
A curve graph of 31 days after the date trace is created and the graph display operation is completed.

Note that data from 30 days before the latest 60-day mark can be read at any time.

That is, the body temperature recording/display device according to the present invention can move the curve graph in the four directions of the number of days axis, read out the data before the 30th day, and display the data in a graph.

Next, predictive display of future body temperature changes by the body temperature recording/display device of the present invention will be explained.

The user first presses the prediction mode start key 24 on the human power section.
When the control/calculation unit CPU receives the input of this key, it reads out the already recorded basal body temperature data from RAM1 of the data memory RAM, and displays it on the display screen LCD.
Display it as a graph above. After that, the control/calculation unit CPU
reads the preset initial cycle number a from RAM3 of the data memory RAM, and displays it on the display screen LCD.
The data is displayed on the upper display section 18, and the ovulation day indicating cursor b is further displayed at the bottom of the latest data display position (right end of the screen) (see FIG. 7).

Next, the user moves the chevron-shaped cursor b by pressing the lateral movement keys to and it, and moves the cursor b to the position of the ovulation day read from the graph DG on the screen as shown in FIG. Then, the user presses the cycle manual/ovulation day indication switching key 25, which causes the control/calculation unit CPU to proceed to the cycle input step.

The user then selects the periodic date aa displayed on the display screen LCD by pressing the vertical movement key 12.13.
, and presses the prediction graph display key 26 according to the number of cycles E of the user. When the CPU of the control fist calculation unit receives the manual power of this key, it stores the number of cycle days previously set by the user in the data memory RAM. The data is written to the RAM 3 in preparation for subsequent processing.

The written number of cycle days is saved in the data memory RAM along with the body temperature data, and this value will be used when starting the prediction mode next time.If the number of cycle days is constant, the user can use the prediction mode. There is no need to reset the number of cycle days each time you use the mode.

Next, the control fist calculation unit CPU uses the RA of the data memory IIAM.
The latest data record is read from M2, and the ovulation day is calculated from the position of the chevron-shaped cursor b previously set by the user.

Thereafter, the control/calculation unit CPU displays the body temperature cycle change model, bar display, and predicted date of cursor placement on the display screen LCD as shown in FIG.

It should be noted that although the cycle of changes in basal body temperature varies from person to person, the manner of change is the same, so it is possible to display this as a modeled graph.

Therefore, the control/calculation unit CPU has a function of displaying the body temperature cycle change model graph, and after calculating the ovulation day as described above, the control/calculation unit CPU displays the body temperature cycle change model graph as shown in FIG. Graph C, bar display d convex cursor e
and the predicted date f at the position of the convex cursor e are displayed on the display screen LCD.

According to the body temperature cycle change model graph C, the basal body temperature rises after the day of ovulation and enters a high temperature period in 1 to 2 days. Approximately two weeks after the day of ovulation, the body temperature drops, entering the low temperature period, and menstruation begins. After that, a period of low temperature continues, and the next egg collection occurs after a certain cycle for each individual from the previous ovulation day, and it is possible to see how the body temperature rises.

Also, the possibility of conception is highest around the day of ovulation, and the possibility becomes extremely low after 3 days have passed since the onset of the high temperature period.

The bar display d clearly indicates the above-mentioned period.

The bar display d shows a different display for each period.0 For example, the menstrual period is indicated by A, the period when the possibility of pregnancy is very high is indicated by thick line C, and the period in which the possibility of pregnancy is very low is indicated by thin line E, and the probability is slightly high. Moderate line mouth for a period.

2. Set the ovulation day by raising one point in the thick line C one step higher.
It is displayed as shown in .

The convex cursor e is displayed at the position of the break between each period indicated by the bar display d. That is, immediately after the prediction graph display key 26 is pressed, it is displayed at the position A1 in FIG.
Figure Bl, CI.

It moves to the DI, A2 position and is displayed.

Further, the predicted date f of the point where the convex cursor e is currently displayed is displayed on the display section 20 of the display screen LCD.

That is, when the prediction graph display key 26 is pressed, the control/calculation unit CPU displays AI, Bl, CI, Dl, A.
The predicted date of each point in step 2 is calculated based on the ovulation day and the number of cycle days previously set by the user.

The meanings of the points indicated by At, Bl, CI, DI, and A2 and their calculation methods are as follows.

A1: Start of the next menstrual period following the specified ovulation day Go+14 B1: Start of the next period with high pregnancy potential Go+n-
3 01 Day of secondary ovulation Co+nD1: End of period with high possibility of next pregnancy Go+n+I A2: Day of start of next menstrual period AI+n where C
o is the specified ovulation date, and n is the number of cycle days.

The control/calculation unit CPU calculates each predicted date according to the calculation method described above, and first, the predicted date of the point At is displayed on the display screen LCD. After that, the lateral movement key 10.
Every time I receive 11 input.

The predicted date f of Bl, CI, DI, and A2 is displayed on the display section 20. Thereafter, each time the horizontal movement key 10.11 is input, the predicted dates f of Bl, CI, Di, and A2 are displayed.

The user can also predict the next cycle of the prediction graph C displayed on the screen. In this case, the user presses the prediction graph display key 26 again, and the control/calculation unit CP
If U subtracts this key human power, the further calculated AI, Bl
. . . A date is calculated by adding the number of cycle days n to the date of A2, and the display of the predicted date on the display screen LCD is updated. In the same way, the user can know future predicted dates one after another.

Effects of the Invention In short, according to the present invention, by simply inputting the number of days in the body temperature change cycle and the day of ovulation, it is possible to predict the future fertile period, menstrual period, ovulation day, etc. with some degree of accuracy based on this information. , is extremely useful as a female thermometer for pregnancy control.

In other words, a woman's basal body temperature changes periodically, and by understanding the number of days in the temperature change cycle and the day of ovulation from the records, it is possible to accurately predict future fertile periods, menstrual dates, ovulation days, etc. based on these records. It is possible to predict and can be used as a reference for conception control, etc.

The present invention has the advantage that by storing only the number of cycle days and the day of ovulation, it is possible to know the predicted date of each point in the future without any special knowledge.
