Abstract
Abstract A disposable probe cover for a heat sensing probe system, which includes a probe member and a heat sensitive element sealingly engaged with and mounted on the probe member, the probe cover comprising a body section and a thermally conductive contact section sealingly engageable with the probe member for forming a thermal chamber, between the probe member and probe cover, including the contact section and heat sensing element spaced from each other, and a low thermal conductivity fluid medium for transferring heat from the contact section to the heat sensitive element.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
121 words
A heat sensing probe system comprising a probe member, a heat sensitive element sealingly engaged with and mounted on said probe member, separate and independent of said probe cover, and a disposable probe cover for mounting on said probe member, said probe cover including a body section and a tip including a thermally conductive contact section sealingly interconnected with said body section, said tip being contiguous to and in sealed engagement with said probe member for forming a thermal chamber, between said probe member and said contact section, by said contact section and said heat sensing element being spaced from each other and a low thermal conductivity fluid medium for transferring heat from said contact section to said heat sensitive element.
Claim 2
Dependent Claim
121 words
A heat sensing probe system comprising a probe member, a heat sensitive element sealingly engaged with and mounted on said probe member, separate and independent of said probe cover, and a disposable probe cover for mounting on said probe member, said probe cover including a body section and a tip including a thermally conductive contact section sealingly interconnected with said body section, said tip being contiguous to and in sealed engagement with said probe member for forming a thermal chamber, between said probe member and said contact section, by said contact section and said heat sensing element being spaced from each other and a low thermal conductivity fluid medium for transferring heat from said contact section to said heat sensitive element.
Claim 3
Dependent Claim
24 words
The heat sensing probe system of claim 1 in which said probe member includes a tube and said heat sensing element is mounted therein.
Claim 4
Dependent Claim
35 words
The heat sensing probe system of claim 1 in which said probe member includes a biasing mecHanism for positively urging said probe cover into sealing engagement with said probe member to form said thermal chamber.
Claim 5
Dependent Claim
35 words
The heat sensing probe system of claim 2 in which at least one of the end of said tube which engages said probe cover and the portion of the probe cover so engaged is flexible.
Claim 6
Dependent Claim
38 words
The heat sensing probe system of claim 4 in which the portion of said probe cover which receives said end of said tube is tapered for increasing the engaging force between said probe member and said probe cover.
Claim 7
Dependent Claim
128 words
A probe cover holding mechanism comprising a housing, at least one locking element for holding a probe cover and one ejection element for ejecting a aprobe cover, an actuator slidably movable in said housing and connected to said elements, a probe member separate and independent of said probe cover and extending from said actuator forwardly, externally of said housing, a guide member for guiding said elements in their forward and rearward movements, a biasing structure for urging said actuator, and said elements rearwardly for compelling said probe cover to sealingly engage said probe member and cam means for spreading said locking elements as they move forwardly against the force of said biasing structure and retracting them as they are moved rearwardly with the force of said biasing structure.
Claim 8
Dependent Claim
128 words
A probe cover holding mechanism comprising a housing, at least one locking element for holding a probe cover and one ejection element for ejecting a aprobe cover, an actuator slidably movable in said housing and connected to said elements, a probe member separate and independent of said probe cover and extending from said actuator forwardly, externally of said housing, a guide member for guiding said elements in their forward and rearward movements, a biasing structure for urging said actuator, and said elements rearwardly for compelling said probe cover to sealingly engage said probe member and cam means for spreading said locking elements as they move forwardly against the force of said biasing structure and retracting them as they are moved rearwardly with the force of said biasing structure.
