Abstract
An electronic clinical thermometer has a probe including a temperature sensor and a heat flux sensor which are controlled to make measurements at specified time intervals. The measured values are used in solving the equation of heat conduction to estimate the temperature of an internal body position. A heater may be included to preheat a body part in order to reduce the time required for measurement. The probe may use two temperature sensors to measure temperatures at two body surface positions through insulating members which are different in thermal conductivity.
