ABSTRACT:
A quick registering thermometer utilizing a sensor that has electrical resistance varying with temperature located at the tip of a probe, the sensor having relatively small thermal mass and short thermal time constant. Within seconds of contact with the patient, the circuitry communicating with the sensor determines the rate of change in resistance of the sensor and, in turn, the temperature that the sensor would reach if allowed the length of time it would need to reach equilibrium with the contact surface of the patient. Based on the equilibrium temperature determined for the surface of the patient, the circuitry calculates and registers the core body temperature. Included in the circuitry is an error adjustment mechanism for changing the calculated temperature as a function of the number of displays of the thermometer in a given period of time.
