Abstract
A probe cover of a tympanic thermometer and tympanic thermometer assembly includes a base and a sheath attached on the base. The base is a ring-shaped thin film object with a central opening permitting pass of the probe of a tympanic thermometer, and is engaged with flanges at the bottom of the probe. The sheath includes a circumferential wall that strains and circles around the sidewall of the probe, and an infrared window fitted on an opening at the front end of the probe. Since the thickness of the infrared window is thicker than that of the circumferential wall and the infrared window is free of pleats to keep a very uniform thickness, infrared can accurately penetrate through the infrared window to the probe of a tympanic thermometer for measuring a precise body temperature.
