ABSTRACT:
In a predicting-type electronic clinical thermometer, data acquired from a temperature sensor (51) at a very small time interval (.DELTA.t) is read in on a real-time basis, the data is converted into detected temperature (T) by means of a processor (9), the temperature is stored in a memory (7) and a temperature prediction is performed to obtain a predicted temperature (Tp). The rate of change (.DELTA.T/.DELTA.t) in the detected temperature is obtained based upon the detected temperature (T). The moment at which this rate of change attains a predetermined value is taken as an opportunity to check the temporal fluctuation of the predicted temperature within a fixed reference time range. If the predicted temperature is found to have stabilized, the temperature detection is terminated. If it has not stabilized, the temperature detection is continued. Thus, the process through which an allowable condition for a valid prediction was realized is investigated looking back a predetermined length of time from the moment at which the condition was realized, and the result of the investigation is applied when evaluating the validity of the prediction. As a result, a highly accurate temperature prediction can be performed even if the circumstances in which the thermometer is being used changes during temperature detection.
