Abstract
A probe cover for a tympanic thermometer probe comprises a generally tubular body having an opening for receiving the thermometer probe and an infrared transparent window at a distal end thereof. In one embodiment, a film support extends radially inward from the distal end of the body and supports an infrared transparent film spanning the window. The film support has an inner edge that is substantially free from corners turning in the plane of the window. A plurality of end ribs are spaced apart and disposed about an inner circumference of the distal end of the body to engage a distal end of the thermometer probe and form an insulating gap by preventing contact of the film by the thermometer probe. The insulating gap also extends proximally into spaces between the end ribs, reducing thermal contact between the thermometer probe and a circumferential inner surface of the probe cover.
