ABSTRACT:
An electronic clinical thermometer capable of executing plural temperature prediction functions in which elapsed measurement time is a variable, each function prescribing a temperature change up to a final, stable temperature. One of the temperature prediction functions is set, and actual body temperature is sensed at a specific point in time. Then, based on the sensed temperature and selected function, a final temperature is obtained at least twice in accordance with a time series and the temperatures are compared to obtain a difference between them. When the difference falls outside prescribed limits, a new temperature prediction function is selected, a final temperature is obtained based thereon, and the foregoing process is repeated until a difference is found which lies within the prescribed limits. The final temperature obtained at such time is delivered as an output indicative of measured temperature.
