Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
In combination, a probe member and a disposable probe cover attachable thereto, said probe member having a handle and an elongated generally cylindrical metallic probe element depending outwardly therefrom, said probe element being deformed to define at least one integral, substantially rigid salient section flaring outwardly from a longitudinal axis of said probe element and towards said handle portion, said section terminating in a sharp edge, said probe cover being composed of a material deformable and penetrable relatively to the metallic material of said section, said handle portion including means for slidably inserting said probe element into said probe cover, said means for inserting forcing said probe cover to deform over said salient section and causing said sharp edge to inscribe itself fixedly into said probe cover, whereby said probe cover is rigidly mounted onto said probe member.
Claim 2
Dependent Claim
138 words
In combination, a probe member and a disposable probe cover attachable thereto, said probe member having a handle and an elongated generally cylindrical metallic probe element depending outwardly therefrom, said probe element being deformed to define at least one integral, substantially rigid salient section flaring outwardly from a longitudinal axis of said probe element and towards said handle portion, said section terminating in a sharp edge, said probe cover being composed of a material deformable and penetrable relatively to the metallic material of said section, said handle portion including means for slidably inserting said probe element into said probe cover, said means for inserting forcing said probe cover to deform over said salient section and causing said sharp edge to inscribe itself fixedly into said probe cover, whereby said probe cover is rigidly mounted onto said probe member.
Claim 3
Dependent Claim
54 words
Apparatus as described in claim 1 wherein said handle portion further includes plunger means, slidably movable with respect to said means for inserting, for exerting removal force against said probe cover and against the sharp edge of said section, and for forcing said sharp edge to cut its way free of said probe cover.
Claim 4
Dependent Claim
15 words
The probe member of claim 2 in which said sharp edge is a knife edge.
Claim 5
Dependent Claim
30 words
The probe member of claim 3 in which said salient section holds said probe cover in place with its tip sealingly engaged with the free end of said probe element.
Claim 6
Dependent Claim
16 words
The probe member of claim 3 in which said salient section has a thin cross section.
Claim 7
Dependent Claim
52 words
Apparatus as described in claim 1 wherein said probe element includes a first tubular portion extending outwardly from said handle portion, and a second tubular portion connectably fit over the end of said first portion opposite said handle, said tubular portion being flared outwardly at its end fitting over said first portion.
Claim 8
Dependent Claim
24 words
Apparatus as described in claim 1 wherein said salient sections are formed as finned elements cut partially and bent outwardly from said probe element.
