ABSTRACT:
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.
