Infrared medical thermometer
First Claim
1. Infrared medical thermometer comprising:
- a housing adapted to be held in a user'"'"'s hand;
an elongated probe adapted to be inserted into a patient'"'"'s ear canal to receive infrared radiation and provide a signal indicating the patient'"'"'s body temperature;
extension/retraction means for selectively extending the elongated probe to an operative position outside the housing when a patient'"'"'s temperature is to be measured and for selectively retracting the elongated probe to an inoperative position fully within the housing when the measurement has been completed; and
probe cover means for positioning a protective cover in alignment with the elongated probe while the probe is retracted within the housing such that, when the extension/retraction mean selectively extends the probe to its operative position, the protective cover is automatically placed over the probe.

Abstract
A self-contained handheld infrared medical thermometer having an elongated probe that is reciprocably movable between a retracted position, located fully within the thermometer housing, and an extended position, located exterior to the housing. When extended, the probe 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, a reference plate is pivoted in front of the probe, to facilitate calibration. Advancement of the probe to its extended, operative position automatically pivots the reference plate away from the advancing probe and, in addition, automatically advances a disposable protective cover from a container for a large number of such covers into a position where it automatically stretches over the advancing probe to provide hygienic protection.

17. Infrared thermometer apparatus comprising:
-
a housing adapted to be held in a user'"'"'s hand; an elongated probe having a longitudinal axis and adapted to be inserted into a patient'"'"'s ear to receive infrared radiation and provide a signal indicating the patient'"'"'s body temperature; extension/retraction means for selectively extending the elongated probe along its longitudinal axis to an operative position outside the housing when a patient'"'"'s temperature is to be measured and for selectively retracting the elongated probe along its longitudinal axis to an inoperative position fully within the housing when the measurement has been completed; a container located within the housing and carrying a plurality of substantially identical protective covers connected together end-to-end to form an elongated chain, wherein each protective cover includes a substantially flat base with a central aperture and further includes a stretchable plastic film extending across the aperture; and wherein each adjacent pair of protective covers in the elongated chain is connected together by a narrow strip aligned with the centers of the covers; probe cover means having a pawl with a U-shaped end adapted to engage the rearward edge of the end-most adjacent cover, to move the end-most cover into alignment protective cover in the elongated chain, on opposite sides of the narrow strip connecting the end-most cover with the with the elongated probe while the probe is retracted within the housing such that, when the extension/retraction means selectively extends the probe to its operative position, the protective cover automatically covers the probe; wherein the extension/retraction means is operable, while it extends the elongated probe to its operative position, to move the probe through the central aperture of the protective cover and stretch the plastic film over the probe, and the extension/retraction means is further operable, while it retracts the elongated probe to its inoperative position, to automatically remove the protective cover from the probe; a calibration reference located within the housing and movable between a position directly in front of the elongated probe when the probe is retracted to its inoperative position fully within the housing and a position alongside the elongated probe when the probe is extended to its operative position outside the housing; and selectable actuator means for substantially simultaneously conditioning the calibration reference to move to its position alongside the elongated probe, conditioning the probe cover means to position a protective cover in alignment with the elongated probe, and conditioning the extension/retraction means to extend the elongated probe to its operative position, wherein the selectable actuator means further includes means for substantially simultaneously conditioning the extension/retraction means to retract the elongated probe to its inoperative position, conditioning the pawl of the probe cover means to engage a further protective cover, and conditioning the calibration reference to move to its position directly in front of the elongated probe.
