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.
