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: 10
Claim 1
Independent Claim
68 words
An orthopedic traction harness comprising: a traction band dimensioned for placement directly against the skin around the limb to be placed in traction, said traction band being of laminate construction having at least one layer of a two-way stretch material and one layer of a unidirectional stretch mesh; and a stirrup attached to an end portion of said traction band and adapted to have a load attached thereto.
Claim 2
Dependent Claim
68 words
An orthopedic traction harness comprising: a traction band dimensioned for placement directly against the skin around the limb to be placed in traction, said traction band being of laminate construction having at least one layer of a two-way stretch material and one layer of a unidirectional stretch mesh; and a stirrup attached to an end portion of said traction band and adapted to have a load attached thereto.
Claim 3
Dependent Claim
45 words
An orthopedic traction harness as recited in claim 1 further including pressure means for placement around said traction band to apply substantially constant pressure on said band and to urge said traction band uniformly against the skin of the limb to be placed in traction.
Claim 4
Dependent Claim
33 words
A orthopedic traction harness as recited in claim 2 in which said pressure means comprises a pneumatic pressure cuff, said cuff including means to pump up the pressure therein to a desired pressure.
Claim 5
Dependent Claim
26 words
An orthopedic traction harness as recited in claim 2 in which said layer of two-way stretch material is neoprene and is placed directly against the skin.
Claim 6
Dependent Claim
29 words
An orthopedic traction harness as recited in claim 2 in which said traction band includes two layers of two-way stretch material which sandwiches said unidirectional stretch mesh between them.
Claim 7
Dependent Claim
25 words
An orthopedic traction harness as recited in claim 5 in which at least the layer of two-way stretch material immediately adjacent the skin is neoprene.
Claim 8
Dependent Claim
30 words
An orthopedic traction harness as recited in claim 6 in which the unidirectional stretch mesh is oriented such that the direction of stretch is orthogonal to the direction of traction.
Claim 9
Dependent Claim
53 words
An orthopedic traction harness as recited in claim 2 in which said traction band has a pair of edges in a direction substantially parallel to the direction of traction and which further includes fastening means along said edges which cooperates to fasten said band securely around the limb to be placed into traction.
Claim 10
Dependent Claim
20 words
An orthopedic traction harness as recited in claim 8 in which said fastening means comprises loop and hook Velcro-type pads.
