ABSTRACT:
An improved prediction-type medical thermometer that provides an accurate estimate of a patient's temperature in substantially reduced time as compared to prior thermometers of this kind. This improved performance is achieved by using a special hollow probe tip having a low heat capacity and incorporating a resistive heater that is actuated only upon removal of the probe from a base housing. In particular, a processor measures an initial temperature upon the probe's removal and applies to the heater an initial electrical signal having prescribed parameter, e.g., pulse duration, that varies according to the initial temperature measurement. This warms the probe to a prescribed temperature at or near about 93.degree. F., after which the processor applies a sequence of pulses to the heater, to controllably regulate the probe's temperature to the prescribed value.
