Abstract

A digital thermometer with enhanced conformity to the anatomy, such as in and around the mouth of a human being. A non-linear probe has a temperature sensor at a first end adapted to be inserted into the mouth and under the tongue, and a downwardly disposed housing portion at the second end. An intermediate portion of the probe is shaped to rest on the lower lip and/or teeth. The probe can be rotatably or pivotally attached to the housing to protect the probe by being recessed in the housing when not in use and/or to adjust to any size mouth. A plurality of ribs at the intermediate portion of the probe can be included to contact the lips and/or teeth for greater positional stability of the thermometer. A display component displays the measured temperature. Electronic circuitry receives a temperature signal from the temperature sensor, translates the signal into a value representative of the measured temperature, and provides the translated value to the display for displaying the temperature.
