Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
148 words
A pneumatic splint-like device of the type to be applied circumferentially around a portion of the body, such as the knee-joint, to provide support and protection and so as not to impede arterial or venous circulation therefor comprising, inner and outer sections made from a resilient fabric material, said inner section comprising a plurality of pneumatically inter-connected generally circular hollow tubes, said outer section comprising a plurality of pneumatically inter-connected longitudinal hollow tubes extending generally at right angles to said inner tubes, said inner circular and outer longitudinal tubes are pneumatically inter-connected by a plurality of apertures so as to be substantially simultaneously inflated to the same approximate pressure, and said outer longitudinal tubes having greater flexion characteristics than said inner circular tubes whereby said inner circular tubes act as air reservoirs so as to return excess pressure to said outer longitudinal bundles upon extension of said knee-joint.
Claim 2
Dependent Claim
148 words
A pneumatic splint-like device of the type to be applied circumferentially around a portion of the body, such as the knee-joint, to provide support and protection and so as not to impede arterial or venous circulation therefor comprising, inner and outer sections made from a resilient fabric material, said inner section comprising a plurality of pneumatically inter-connected generally circular hollow tubes, said outer section comprising a plurality of pneumatically inter-connected longitudinal hollow tubes extending generally at right angles to said inner tubes, said inner circular and outer longitudinal tubes are pneumatically inter-connected by a plurality of apertures so as to be substantially simultaneously inflated to the same approximate pressure, and said outer longitudinal tubes having greater flexion characteristics than said inner circular tubes whereby said inner circular tubes act as air reservoirs so as to return excess pressure to said outer longitudinal bundles upon extension of said knee-joint.
Claim 3
Dependent Claim
30 words
A device made in accordance with claim 1, wherein said outer longitudinal tubes have a greater cross-sectional area as compared to the corresponding cross-sectional area of said inner circular tubes.
Claim 4
Dependent Claim
32 words
A device made in accordance with claim 1, wherein said outer longitudinal tubes have a reduced cross-sectional wall thickness as compared to the corresponding cross-sectional wall thickness of said inner circular tubes.
