<p>PROBLEM TO BE SOLVED: To easily know an ovulatory day for reliably practicing birth control by displaying passed days from the first day of a period when a woman can become pregnant in a current menstrual period to a current date on a display. SOLUTION: A women's clinical thermometer 1 has clock function and calendar function. The thermometer 1 has alarm function, wherein when a preset alarm time is reached, an alarm signal sound is output for approximately 10 minutes from an electronic buzzer to impel to measure a temperature. A temperature sensor 5 is inserted into a mouth of a woman, and when a temperature measuring part 5A attached to the sensor 5 is pushed, temperature measurement is started. Daily temperature data thus measured is recorded in a memory RAM of a computer together with date data. A period when a woman can be pregnant is displayed by a mark M on 2C of a display 2. If a switch 3A is pressed on the first day of a menstrual period, it is registered in the memory RAM. If seven or more days have passed from the first day of the menstrual period and three days when the temperature is higher than the lowest temperature during the current menstrual period by 0.3 deg.C or more have continued, the day three days before is determined to be an ovulatory day.</p> |
