Abstract

A menstruation periodic counter is provided with an indicator of a calendar, an indicator of a bodily temperature chart and temperature measuring time, an input switch for receiving numeral values, and an alarm mechanism for sounding at a time set by the input switch, and wherein the calendar indicator indicates through a cursor information concerning the days obtained from the data for indicating the bodily temperature chart. Automatic adjustment of the range sensitivity of the temperature sensor and correction of out-of-range values, based on expected basal bodily temperature period as predicted by the Ogino method is effected by microprocessor.

Claims

1. A menstruation periodic counter, including a first indicator for indicating a calendar and a second indicator, and an operation switch comprising a switch for switching contents shown in the said second indicator and a switch for inputting numerical values, the counter comprising:

means for issuing an alarm at a time set by said numerical value inputting switch;

a temperature measuring sensor for measuring the basal bodily temperature of a subject when said alarm is issued;

an A-D converter for converting said basal bodily temperature measured by said temperature measuring sensor into a digital signal; and

a microprocessor having a memory for storing digital signal outputs from said A-D converter;

said microprocessor calculating through application of Ogino'"'"'s rhythm method, the conceptive period from a menstruation beginning data value input from said operation switch;

said microprocessor determining from the basal bodily temperature signals the conceptive period when the number of measurements made by said temperature measuring sensor exceeds a number representing the length in days of the menstruation period; and

said microprocessor correcting the conceptive period calculated by said Ogino'"'"'s method by the conceptive period determined from said basal bodily temperature outputs, and indicating the corrected conceptive period on the said first indicator,

said microprocessor discriminating by using said Ogino'"'"'s method and said menstruation beginning data value the condition of a high temperature or a low temperature period in the subject, and providing a signal indicative thereof, and

means responsive to said signal for adjusting the output range of said A-D converter.

4. A device as claimed in claim 1, wherein said microprocessor corrects the value of said digital signal if the basal bodily temperature exceeds a predetermined range, and stores said corrected value in said memory as said basal bodily temperature signal.

5. A device as claimed in claim 1, further comprising a heating circuit for pre-heating the temperature measuring sensor prior to measuring of said basal bodily temperature.

2. A menstruation periodic counter, including a first indicator for indicating a calendar and a second indicator, and an operation switch comprising a switch for swtiching contents shown in the said second indicator and a switch for inputting numerical values, the counter comprising:

means for issuing an alarm at a time set by said numerical value inputting switch;

a temperature measuring sensor for measuring the basal bodily temperature of a subject when said alarm is issued;

an A-D converter for converting said basal bodily temperature measured by said temperature measuring sensor into a digital signal; and

a microprocessor having a memory for storing ditigal signal outputs from said A-D converter;

said microprocessor correcting the value of said digital signal if the basal bodily temperature exceeds a pre-determined range, and storing said corrected value in said memory as said basal bodily temperature signal,

said mircroprocessor calculating through application of Ogino'"'"'s rhythm method, the conceptive period from a menstruation beginning data value input from said operation switch;

said mircroprocessor determining from the basal bodily temperature signals the conceptive period when the number of measurements made by said temperature measuring sensor exceeds a number representing the length in days of the menstruation period; and

said microprocessor correcting the conceptive period calculated by said Ogino'"'"'s method by the conceptive period determined from said basal bodily temperature outputs and indicating the corrected conceptive period on the said first indicator.

3. A device as claimed in claim 2, further comprising a heating circuit for pre-heating the temperature measuring sensor prior to measuring of said basal bodily temperature.
