Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
78 words
A thermally conductive surgical dressing comprising a body of fibrous material having high liquid absorbency, said body having a first surface and a second surface, a plurality of thermally conductive elements distributed throughout said high-absorbency fibrous material between said surfaces, said thermally conductive elements being arranged to establish a heat conductive path through said body between the inner and outer surfaces thereof, to thereby provide a surgical dressing having a high liquid absorbency and uniformly high thermal conductivity.
Claim 2
Dependent Claim
78 words
A thermally conductive surgical dressing comprising a body of fibrous material having high liquid absorbency, said body having a first surface and a second surface, a plurality of thermally conductive elements distributed throughout said high-absorbency fibrous material between said surfaces, said thermally conductive elements being arranged to establish a heat conductive path through said body between the inner and outer surfaces thereof, to thereby provide a surgical dressing having a high liquid absorbency and uniformly high thermal conductivity.
Claim 3
Dependent Claim
49 words
A surgical dressing according to claim 1 which includes yarns interwoven to form a layer of gauze, wherein each of said yarns comprises at least one strand of highly absorbent fibrous material and at least one strand of a high thermally conductive metal spun together to form said yarns.
Claim 4
Dependent Claim
33 words
A surgical dressing according to claim 1 which includes a least one layer of gauze formed of alternately interwoven yarns of highly absorbent fibrous material and yarns of thermally conductive fine metallic strands.
Claim 5
Dependent Claim
36 words
A surgical dressing according to claim 1 which includes at least one layer of gauze formed of interwoven fibrous yarns having a high degree of absorbency, and particles of thermally conductive particles impregnated in said yarns.
Claim 6
Dependent Claim
22 words
A surgical dressing according to claim 1 which includes alternate layers of thermally conductive fine wire mesh gauze and absorbent fibrous gauze.
Claim 7
Dependent Claim
22 words
A surgical dressing according to claim 1 which includes a wad of highly absorbent fibrous material impregnated with thermally conductive metallic particles.
Claim 8
Dependent Claim
29 words
A surgical dressing according to claim 1 which includes at least one adhesive strip secured to said surgical dressing, said adhesive strip including thermally conductive metallic particles impregnated therein.
Claim 9
Dependent Claim
41 words
A surgical dressing according to claim 1 which includes a thick layer of highly absorbent fibrous material and at least one layer of thermally conductive metallic gauze on each of the top and bottom surfaces of said layer of fibrous material.
Claim 10
Dependent Claim
13 words
A surgical dressing according to claim 1 wherein said fibrous material comprises cotton.
Claim 11
Dependent Claim
15 words
An article of clothing formed of the material comprising surgical dressing according to claim 1.
