Abstract
Abstract A unitary orthopedic cast material is provided which comprises a layer of plaster splint material, a relatively thick padding layer on one side of the plaster splint material, and a resilient covering fabric enclosing the plaster splint layer and the padding layer. The padding layer and covering fabric are each fabricated from a hydrophobic textile material, such as polypropylene fibers, which acts to wick moisture from the skin of the wearer to the outer surface of the cast material, where the moisture readily evaporates, to thereby alleviate skin irritation and odor beneath the cast.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
72 words
A prepadded, unitized orthopedic cast material characterized by the ability to be quickly applied, and improved comfort to the wearer, and comprising a layer of plaster splint material, a relatively thick padding layer comprising a hydrophobic textile material overlying at least one side of said plaster splint layer, and a covering fabric comprising a hydrophobic textile material enclosing said plaster splint layer and said padding layer, to thereby maintain the assembly thereof.
Claim 2
Dependent Claim
72 words
A prepadded, unitized orthopedic cast material characterized by the ability to be quickly applied, and improved comfort to the wearer, and comprising a layer of plaster splint material, a relatively thick padding layer comprising a hydrophobic textile material overlying at least one side of said plaster splint layer, and a covering fabric comprising a hydrophobic textile material enclosing said plaster splint layer and said padding layer, to thereby maintain the assembly thereof.
Claim 3
Dependent Claim
31 words
The orthopedic cast material as defined in claim 1 wherein said hydrophobic textile material of each of said padding layer and said covering fabric consists essentially of a non-wetting polymeric material.
Claim 4
Dependent Claim
22 words
The orthopedic cast material as defined in claim 2 wherein said padding layer comprises at least one sheet of a non-woven fabric.
Claim 5
Dependent Claim
19 words
The orthopedic cast material as defined in claim 3 wherein said covering fabric is of a resilient knit construction.
Claim 6
Dependent Claim
25 words
The orthopedic cast material as defined in claim 4 wherein said layer of plaster splint material comprises a plurality of superposed sheets for such material.
Claim 7
Dependent Claim
35 words
The orthopedic cast material as defined in claim 1 wherein said hydrophobic textile material of each of said padding layer and resilient covering fabric consists essentially of polymeric fibers having an antimicrobial agent carried thereby.
Claim 8
Dependent Claim
27 words
The orthopedic cast material as defined in claim 1 wherein said padding layer overlies one side and the two longitudinal side edges of said plaster splint layer.
Claim 9
Dependent Claim
48 words
The orthopedic cast material as defined in claim 1 wherein said cast material is of a four-sided configuration in plan view, and wherein the four side edges of said covering fabric are closed so as to totally enclose the layer of plaster splint material and padding layer therewithin.
Claim 10
Dependent Claim
80 words
A prepadded, unitized orthopedic cast material characterized by the ability to be quickly applied, and improved comfort to the wearer, and comprising a plurality of superposed sheets of plaster splint material, a relatively thick padding layer of non-woven hydrophobic textile material overlying at least one side of said sheets of plaster splint material, and a tubular stockinet of resilient hydrophobic knit fabric material enclosing said sheets of plaster splint material and said padding layer, to thereby maintain the assembly thereof.
Claim 11
Dependent Claim
80 words
A prepadded, unitized orthopedic cast material characterized by the ability to be quickly applied, and improved comfort to the wearer, and comprising a plurality of superposed sheets of plaster splint material, a relatively thick padding layer of non-woven hydrophobic textile material overlying at least one side of said sheets of plaster splint material, and a tubular stockinet of resilient hydrophobic knit fabric material enclosing said sheets of plaster splint material and said padding layer, to thereby maintain the assembly thereof.
Claim 12
Dependent Claim
33 words
The orthopedic cast material as defined in claim 9 wherein said cast material is of elongate, relatively narrow configuration, and further includes a line of sinusoidal stitching extending along the longitudinal length thereof.
Claim 13
Dependent Claim
34 words
The orthopedic cast material as defined in claim 10 wherein said padding layer overlies one side, the two longitudinal side edges, and a portion only of the other side, of said plaster splint material.
Claim 14
Dependent Claim
33 words
The orthopedic cast as defined in claim 11 wherein said sinusoidal line of stitching engages at longitudinally spaced locations said portion of said padding overlying said other side of said plaster splint material.
Claim 15
Dependent Claim
74 words
The orthopedic cast material as defined in claim 11 wherein said sinusoidal line of stitching comprises threads of differing color, with the thread of one color being visible on one side of the cast material and the other thread being visible on the other side, whereby the thread colors serve to distinguish the two sides of the cast material and thereby facilitate its application with the padded side adjacent the body of the patient.
Claim 16
Dependent Claim
29 words
The orthopedic cast material as defined in claim 9 wherein said padding layer and said stockinet each consist essentially of polypropylene fibers having an anti-microbial agent intimately admixed therein.
