Abstract: A self-contained handheld infrared medical thermometer having an elongated probe (15) that is reciprocably movable between a retracted position, located fully within the thermometer housing (11), and an extended position, located exterior to the housing. When extended, the probe (15) is adapted for insertion into a patient's outer ear canal to measure the patient's body temperature. When the probe is retracted within the housing (11), a reference plate (21) is pivoted in front of the probe (15), to facilitate calibration. Advancement of the probe (15), to its extended, operative position automatically pivots the reference plate (21) away from the advancing probe (15) and, in addition, automatically advances a disposable protective cover (43), from a container (45) for a large number of such covers into a position where it automatically stretches over the advancing probe (15) to provide hygienic protection.
