Abstract
An electronic clinical thermometer has a probe including a variable-temperature heater and one or more temperature sensors and may also include a heat flux sensor. Physical variables such as temperature, time rate of change in temperature and/or heat flow rate are directly measured at positions on the surface of a patient while being heated by the heater through a thermally insulating member. Such measured values are used to solve a heat transfer equation rewritten as lower-order equations. Measurements may be controlled to be taken at a desired timing such as at specified intervals. The probe for contacting the patient'"'"'s body may be planar or in an elongated bar-shape.
