Abstract

See full text

A disposable probe cover for an electronic tympanic ('ear') thermometer is made of closed-cell foam that is laminated with a sheet of high density polyethylene plastic film substantially transparent to infrared radiant energy. The probe cover is hollow, defining a central passageway that accepts an oversized probe and can potentially accommodate a variety of different probe configurations. The foam construction allows the probe cover to stretch over the oversized probe--retaining the probe cover on the probe during use. The foam construction also allows the probe cover to deform when inserted into a patient's ear--sealing the patient's ear canal to prevent external heat and light from affecting the measurement, and providing a high degree of cushioning and comfort not available in any prior disposable probe cover design. The film laminate and foam provide a barrier that is impervious to germs, fluids and other secretions--further reducing the already low risk of cross-contamination. The probe cover design facilitates accurate, repeatable measurements using a temperature measuring instrument based on receiving and analyzing the radiant infrared heat energy emitted by the tympanic membrane (eardrum).
