Abstract
Abstract An orthopedic traction harness which engages the skin around the limb to be put in traction. The traction harness comprises an inner, circumferentially adjustable, laminated traction band having an outer layer of a compressible sponge material, a central layer of a flexible unidirectional stretch mesh and an inner layer of another compressible sponge material, and an outer, variable pneumatic pressure cuff including a flexible air bladder inside an adjustable containment cuff having a squeeze bulb and a pressure indicator.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
55 words
A substantially flat sheet of material comprising: a first layer of two-way stretch material; and at least one pad of unidirectional stretch mesh bonded to said first layer at a selected location thereof and having selected angular orientation to restrict said selected location to a one-way stretch in a direction determined by said selected orientation.
Claim 2
Dependent Claim
55 words
A substantially flat sheet of material comprising: a first layer of two-way stretch material; and at least one pad of unidirectional stretch mesh bonded to said first layer at a selected location thereof and having selected angular orientation to restrict said selected location to a one-way stretch in a direction determined by said selected orientation.
Claim 3
Dependent Claim
34 words
A substantially flat sheet of material as recited in claim 1 in which a plurality of unidirectional stretch mesh pads are bonded to said first layer at selected locations and having selected angular orientations.
Claim 4
Dependent Claim
54 words
A substantially flat sheet of material as recited in claim 2 in which a second layer of two-way stretch material is bonded to the surface of said first layer to which said pads are bonded to form a laminate of two layers of two-way stretch material with unidirectional stretch mesh pads sandwiched between them.
Claim 5
Independent Claim
54 words
The method of restricting the stretch of a piece of two-way stretch material to a one-way stretch at selected locations and in selected directions comprising the step of: bonding a unidirectional stretch mesh to said piece of two-way stretch material of said selected locations and orientation angularly to provide stretch in said selected directions.
Claim 6
Independent Claim
54 words
The method of restricting the stretch of a piece of two-way stretch material to a one-way stretch at selected locations and in selected directions comprising the step of: bonding a unidirectional stretch mesh to said piece of two-way stretch material of said selected locations and orientation angularly to provide stretch in said selected directions.
