Abstract
A probe for use in sensing body temperature includes a longitudinally elongated tubular member having a wall defining a hollow interior, a distal end having a closed tip, and a temperature sensing element mounted in the tip producing a signal indicative of the temperature of the tip. A lighted indicia is provided by one or more light passages disposed in the wall of the tubular member and a light emitting device is disposed in operative association therewith for illuminating the light transmissive indicia from interiorly of the tubular member. The lighted indicia is disposed at a selected distance longitudinally inwardly of the end of the tip portion of the probe commensurate with the desired depth of rectal insertion during use of the probe in rectal application. The region in front of the probe may be illuminated by light passing through a light passage in the probe tip.
