Abstract
Abstract A thermometer for temperature measurement of a body is provided wherein a temperature probe electrically connects to a temperature read-out means and a probe cover or sheath fits over such probe. The sheath has a temperature sensor e.g. a thermistor mounted thereon, which sensor is electrically connected to the probe when such probe is inserted into such sheath to provide a rapid measurement and read-out of the temperature of a body. The sheath with temperature sensor is disposable and readily replaced for the next use of the electric thermometer of the invention. Alternatively, the sheath can be sterilized for reuse.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
121 words
An instrument for measuring the temperature of a body and comprising: a probe; probe connector means retained by said probe and adapted for connection to a temperature read-out means, said probe connector means comprising a plurality of electrical conductors on said probe; a cover sheath adapted to be friction fitted over said probe; a temperature sensor means mounted at an end of said cover sheath and extending to an outside surface thereof; and sheath connector means comprising a plurality of electrical conductors in said cover sheath and electrically coupled to said sensor means, said electrical conductors in said cover sheath being shaped and arranged to interconnect with said electrical conductors on said probe with said cover sheath fitted over said probe.
Claim 2
Dependent Claim
121 words
An instrument for measuring the temperature of a body and comprising: a probe; probe connector means retained by said probe and adapted for connection to a temperature read-out means, said probe connector means comprising a plurality of electrical conductors on said probe; a cover sheath adapted to be friction fitted over said probe; a temperature sensor means mounted at an end of said cover sheath and extending to an outside surface thereof; and sheath connector means comprising a plurality of electrical conductors in said cover sheath and electrically coupled to said sensor means, said electrical conductors in said cover sheath being shaped and arranged to interconnect with said electrical conductors on said probe with said cover sheath fitted over said probe.
Claim 3
Dependent Claim
18 words
The instrument of claim 1 wherein said cover sheath is removable from said probe and disposable or reusable.
Claim 4
Dependent Claim
33 words
The instrument of claim 1 wherein said probe and said cover sheath are elongated with clearance between the end of said probe and the portion of said cover sheath supporting said sensor means.
Claim 5
Dependent Claim
35 words
