Electronic clinical thermometer.

摘要

An electronic clinical thermometer which is provided with a bridge circuit (2) having a heat sensitive element (1) connected to at least one side thereof, first detecting means (3, 4) for detecting wheter or not the ratio of increase of a temperature signal from the bridge circuit (2) is higher than a certain value, and second detecting means (5) for detecting, based on the temperature signal from the bridge circuit (2), whether or not the temperature of the heat sensitive element (1) has reached a set temperature substantially equal to the bodily temperature. When it is detected by the first detecting means (3, 4) that the ratio of increase of the temperature signal has become higher than the certain value, the heat sensitive element (1) is made to be self-heated up to the set temperature substantially equal to the bodily temperature, by which the bodily temperature can be measured in a short time and with small power dissipation.
