1. A tympanic thermometer having a proximal end and a distal end, the thermometer comprising:
- a thermally conductive nozzle extending from the distal end of the thermometer, the nozzle being located and shaped to receive a probe cover thereon, a sensor can housing temperature sensing electronics for sensing temperature, the sensor can including a base thermally connected to the nozzle to define a path of conductive heat transfer from the nozzle to the base of the can, the sensor can being otherwise free of thermal connection with a thermally conductive structure of greater mass than the sensor can.

Abstract
A tympanic thermometer includes a thermally conductive nozzle extending from a distal end of the thermometer. A base of a sensor can is thermally connected to the nozzle to define a path of conductive heat transfer from the nozzle to the base of the can thereby minimizing a thermal gradient between proximal and distal ends of the sensor can when temperature is measured in the ear.
