Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
58 words
An orthopedic cast forming composition for immobilizing a patient's body or portions thereof, said composition comprising a flexible fabric having coated thereon a water-curable prepolymer resin, said prepolymer being one produced by the reaction of an isocyanate with a polyol into which a colorant had been mixed prior to said reaction, said colorant being non-reactive to said patient.
Claim 2
Dependent Claim
58 words
An orthopedic cast forming composition for immobilizing a patient's body or portions thereof, said composition comprising a flexible fabric having coated thereon a water-curable prepolymer resin, said prepolymer being one produced by the reaction of an isocyanate with a polyol into which a colorant had been mixed prior to said reaction, said colorant being non-reactive to said patient.
Claim 3
Dependent Claim
24 words
The composition of claim 1 wherein said fabric is a knit fiberglass of mesh size within the range of 250-280 openings per square inch.
Claim 4
Dependent Claim
19 words
The composition of claim 1 wherein said fabric is fiberglass of mesh size having 265 openings per square inch.
Claim 5
Dependent Claim
10 words
The composition of claim 1 wherein said colorant is blue.
Claim 6
Dependent Claim
24 words
The composition of claim 4 where said colorant is formed of 0.07% by weight of blue colorant and 0.007% by weight of pink colorant.
Claim 7
Dependent Claim
10 words

Claim 8
Dependent Claim
16 words
The composition of claim 6 wherein said colorant is pink in concentration of 0.01% by weight.
Claim 9
Dependent Claim
80 words
A colored orthopedic cast-forming composition for immobilizing a patient's body or portions thereof, said composition comprising a flexible fabric having coated thereon a water-curable prepolymer resin formed by the reaction of one reactant with another reactant wherein the latter reactant was one with which a colorant had been intermixed prior to conducting said reaction, said colorant being one which is patient non-reactive and does not interfere with the shelf life and strength or rapid-hardening characteristics of the cast forming composition.
Claim 10
Dependent Claim
80 words
A colored orthopedic cast-forming composition for immobilizing a patient's body or portions thereof, said composition comprising a flexible fabric having coated thereon a water-curable prepolymer resin formed by the reaction of one reactant with another reactant wherein the latter reactant was one with which a colorant had been intermixed prior to conducting said reaction, said colorant being one which is patient non-reactive and does not interfere with the shelf life and strength or rapid-hardening characteristics of the cast forming composition.
Claim 11
Dependent Claim
24 words
The composition of claim 8 wherein said fabric is a knit fiberglass of mesh size within the range of 250-280 openings per square inch.
Claim 12
Dependent Claim
19 words
The composition of claim 8 wherein said fabric is fiberglass of mesh size having 265 openings per square inch.
Claim 13
Dependent Claim
