Abstract
Abstract A pressure bandage whereby heat is directly transmitted to the body and the therapeutic effect is substantially improved by applying a heatable bandage under pull and pressure to the part of the body to be treated. To this end the heatable pressure bandage is elastically extensible and has self-adhering closures enabling proper application of the bandage to parts of different size of a body.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
145 words
A therapeutic bandage comprising a pair of planar sheets defining a bandage body, a heating element including electric conductor means sealed between said sheets, a supply cable including electric conductors and having one end disposed between said sheets, the ends of said conductor means and said conductors being electrically connected, releasable fastening means on opposed edge portions of said bandage body for cooperatively securing said bandage in operative position, said sheets and heating element being elastically extensible, and pressure proof and inextensible capsules adhered between said sheets and enclosing said electric connections between said conductor means and conductors to relieve said connections of any stress, whereby said bandage and heating element may be stretched over a portion of a body and securely retained in position by said fastening means to preclude air spaces therebetween and uniformly apply pressure and heat to the covered body arEa.
Claim 2
Dependent Claim
145 words
A therapeutic bandage comprising a pair of planar sheets defining a bandage body, a heating element including electric conductor means sealed between said sheets, a supply cable including electric conductors and having one end disposed between said sheets, the ends of said conductor means and said conductors being electrically connected, releasable fastening means on opposed edge portions of said bandage body for cooperatively securing said bandage in operative position, said sheets and heating element being elastically extensible, and pressure proof and inextensible capsules adhered between said sheets and enclosing said electric connections between said conductor means and conductors to relieve said connections of any stress, whereby said bandage and heating element may be stretched over a portion of a body and securely retained in position by said fastening means to preclude air spaces therebetween and uniformly apply pressure and heat to the covered body arEa.
Claim 3
Dependent Claim
29 words
A bandage according to claim 1, wherein said elastically extensible heating element comprises an elongated cable-like member and is cemented with and between said sheets which comprise prevulcanized rubber.
Claim 4
Dependent Claim
38 words
A bandage according to claim 2, wherein said heating element comprises an elastically extensible core a flexible copper litz braided along a helical line around said core with a plait of elastic insulating yarn enclosing said extensible core.
Claim 5
Dependent Claim
35 words
A bandage according to claim 3, wherein the ends of said cable and the ends of said heating element are surrounded by an insulating sleeve and clamped where led though the walls of said capsules.
Claim 6
Dependent Claim
42 words
A bandage according to claim 4, wherein said conductors of the cable and connecting ends of said core and heating conductor respectively are clamped between cuttings of the wall of a capsule body and a capsule cover fixed to the capsule body.
Claim 7
Dependent Claim
34 words
A bandage according to claim 1, wherein said heating conductor is disposed along a zig-zag line with parallel straight portions of the conductor at a distance of 1.5 to 3.5 mm from each other.
Claim 8
Dependent Claim
25 words
A bandage according to claim 1, wherein said heating conductor is connected to a low-voltage source designed for a maximum heating power of 0.043 W/cm2.
Claim 9
Dependent Claim
42 words
A bandage according to claim 1, wherein said fastening means comprises pads of self-adhering closure means disposed at opposite sides of said elastically extensible sheets and at least at one end of said bandage outside the area covered by the heating conductor.
Claim 10
Independent Claim
71 words
A method for producing a pressure bandage for heat treatment of parts of a human or animal body and comprising an elastically extensible heating element enclosed and sealed between elastically extensible sheets, wherein said heating element is cemented in the desired disposition to the inner side of a first vulcanized rubber sheet, whereafter a second vulcanized rubber sheet is cemented to the first rubber sheet and to said heating element respectively.
Claim 11
Independent Claim
71 words
A method for producing a pressure bandage for heat treatment of parts of a human or animal body and comprising an elastically extensible heating element enclosed and sealed between elastically extensible sheets, wherein said heating element is cemented in the desired disposition to the inner side of a first vulcanized rubber sheet, whereafter a second vulcanized rubber sheet is cemented to the first rubber sheet and to said heating element respectively.
Claim 12
Dependent Claim
121 words
A method according to claim 9, wherein said heating conductor is first applied in zig-zag configuration around pins inserted into a flat gauge wherein said pins are shiftable in a direction perpendicular to the plane of the gauge but are secured against removal from the gauge, whereafter a cement is applied to the one surface of one of said rubber sheets and the gauge is applied against this surface with the heating conductor engaging said surface and cement applied thereto respectively, whereafter said gauge is removed as soon as the cement has sufficiently hardened for binding said heating conductor to said sheet, whereafter said second rubber sheet is applied to the surface of said one rubber sheet carrying the heating conductor.
Claim 13
Dependent Claim
26 words
A method according to claim 10, wherein hardening of the cement is accelerated by connection of the heating conductor to an electric source for heating it.
Claim 14
Dependent Claim
17 words
A method according to claim 10, wherein said gauge comprises a flat carrier of transparent insulating material.
Claim 15
Dependent Claim
36 words
A bandage according to claim 1, wherein the elasticity of said sheets enables application substantially throughout the area thereof against the portion of the body under treatment at a pressure in the order of 0.05 Kg/cm2.
Claim 16
Dependent Claim
19 words
A bandage according to claim 1, wherein said bandage has a heating capacity of not more than 0.042 W/cm2.
