Abstract
A clinical thermometer having a probe with a thermopile mounted thereon. The probe is inserted into a connector housing which includes a resistance thermometer for measuring the temperature of the cold junctions of the thermopile. The connector housing includes a portion of an electrical circuit mounted on a circuit board which is electrically connected to the resistance thermometer. The circuit board is electrically connected to a meter box having the remaining portion of the electrical circuit contained therein. The meter box includes a dial which is calibrated in degrees of temperature for visually indicating the temperature sensed by the hot junctions of the thermopile. The probe is releasably secured within the connector housing so that probes can be easily inserted and removed. The clinical thermometer provides a mechanism whereby the body temperature of a patient can be measured quickly and easily and without maintaining the cold junctions of the thermopile at a constant reference temperature.
