摘要： An improved medical thermometer is disclosed 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 configuring the thermometer to include a hollow, thin-walled metallic probe tip sized for secure attachment to the remote end of an elongated base. This defines an elongated cavity within the probe tip, and a thermistor is bonded to the probe tip within that cavity. The cavity is configured to be substantially longer in the direction of the probe's longitudinal axis than it is in a transverse direction, to inhibit the conduction of heat along the probe tip to the elongated base. The temperature of the thermistor, therefore, closely follows the temperature of any surface that contacts the metallic tip.

摘要： 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.
