Abstract

Abstract An improved thermistor holder structure is disclosed which facilitates skin-temperature measurement. The device includes a cylindrical plastic housing with tab extensions that permits the apparatus to be held to a skin surface by suitable elastic members or the like. Ventilation openings are provided in the plastic housing to permit air circulation. An adjustable, resilient metal arm with a thermistor holding cup formed at one end is secured to the interior surface of the plastic housing such that the holding cup is located at the center of the housing. A thermistor temperature sensor is inserted into and held in the cup by interference fit.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 119 words
An apparatus for holding a temperature sensitive element for monitoring skin temperature, comprising: an enclosure having two open ends, one of which is adapted to be placed against said skin; a peripheral wall surrounding said enclosure, said peripheral wall including a plurality of apertures for permitting air circulation within said enclosure; resilient support means secured to the interior of said enclosure for retaining said temperature sensitive element, said resilient support means being adjustable to adjust the biasing force exerted by said temperature sensitive element against said skin, said resilient support means including an arm coupled to said peripheral wall on an interior surface of said enclosure; and tab means secured to said enclosure for retaining said enclosure in place.
Claim 2
Independent Claim 119 words
An apparatus for holding a temperature sensitive element for monitoring skin temperature, comprising: an enclosure having two open ends, one of which is adapted to be placed against said skin; a peripheral wall surrounding said enclosure, said peripheral wall including a plurality of apertures for permitting air circulation within said enclosure; resilient support means secured to the interior of said enclosure for retaining said temperature sensitive element, said resilient support means being adjustable to adjust the biasing force exerted by said temperature sensitive element against said skin, said resilient support means including an arm coupled to said peripheral wall on an interior surface of said enclosure; and tab means secured to said enclosure for retaining said enclosure in place.
Claim 3
Dependent Claim 29 words
