IR thermometer
First Claim
1. In combination in an IR thermometer for measuring radiation emanating from a tympanic membrane of a patient, the improvement comprising an IR wave guide partially encased in a concentric spacer which is further partially encased by a protective sheath wherein said spacer has a first cross-sectional shape that departs from a second cross-sectional shape of said protective sheath or said IR wave guide, thereby creating a series of axially distributed spaces positioned between the spacer and the wave guide or between the spacer and the protective sheath, or between the spacer and the wave guide and between the spacer and the protective sheath.

Abstract
A novel wave guide assembly for use in an IR thermometer of the type used in measuring temperature of the tympanic membrane of the ear for body temperature determinations. The assembly provides a unique arrangement of spacers and a protective sheath to create a durable yet inexpensive wave guide. The spacer includes radially offset contact points that induce moment arms to absorb shock and other forms of rough handling encountered in daily use.
