CLINICAL THERMOMETER

PURPOSE:To make it possible to estimate and measure body temperature at freely selected accuracy by a measuring person from the output of the first fuzzy inference at a fuzzy inference part by displaying the body temperature based on the output from a body-temperature inference part when the display temperature is estimated, and from the actually measured body temperature based on the output of a temperature sensor when the temperature is actually measured; and displaying whether the body temperature is being measured or has been already measured or not from the second fuzzy inference. CONSTITUTION:The following data are imparted to a fuzzy inference part 12 from a data outputting means: selected data at inference accuracy in a body temperature inference mode; analyzed data of the increase in body temperature; and the time-elapse data in body temperature measurement. The inference part 12 performs the following inferences by using said data: first fuzzy inference y1 for determining whether the measured body temperature is based on the inference or the actual measurement in accordance with fuzzy rules; and second fuzzy inference y2 for determining whether at least the body temperature is being measured or has been already measured. Thus the temperature of the inference value outputted from a temperature inference part 10 or the actually measured value outputted directly from a temperature sensor is displayed. At this time, whether the body temperature is being measured or has been already measured can be displayed.
