Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
108 words
A lumbosacral surgical support comprising a substantially rectangular semirigid intermediate panel including a fabricencased core of resilient porous spongelike material secured thereto, first and second elongate opposing end panels of elastic textile fabric connected to and extending outwardly from respective opposing side edges of said intermediate panel, the elastic fabric of said end panels being stretchable both longitudinally and transversely thereof to readily conform to the physiognomy of the patient when worn in the lumbosacral region, and fastening means for detachably interconnecting the distal end portions of said end panels opposite from said intermediate panel when the support is placed about the patient''s trunk in the lumbosacral region.
Claim 2
Dependent Claim
108 words
A lumbosacral surgical support comprising a substantially rectangular semirigid intermediate panel including a fabricencased core of resilient porous spongelike material secured thereto, first and second elongate opposing end panels of elastic textile fabric connected to and extending outwardly from respective opposing side edges of said intermediate panel, the elastic fabric of said end panels being stretchable both longitudinally and transversely thereof to readily conform to the physiognomy of the patient when worn in the lumbosacral region, and fastening means for detachably interconnecting the distal end portions of said end panels opposite from said intermediate panel when the support is placed about the patient''s trunk in the lumbosacral region.
Claim 3
Dependent Claim
51 words
A surgical support according to claim 1, wherein said core is composed of discrete particles of polyurethane foam material bonded together and having a density of about 6 pounds per cubic foot and an enhanced porosity comparable to that of common polyurethane foam of about 2 pounds per cubic foot density.
Claim 4
Dependent Claim
37 words
A surgical support according to claim 1 including a plurality of spaced substantially parallel and transversely extending rows of binder thread stitching penetratingly secured to said intermediate support panel to stabilize said core relative to said fabric.
Claim 5
Dependent Claim
80 words
A surgical support according to claim 1, in which the fabric-encased core includes two layers of fabric sandwiching said spongelike material therebetween, and further comprising a plurality of spaced transverse rows of thread stitching compressively securing the layers of said fabric and said core together in the area of said intermediate support panel, and said rows of stitching serving to hold the core in compressed condition thereat to impart a transversely ribbed configuration to opposing faces of said intermediate panel.
Claim 6
Dependent Claim
31 words
A surgical support according to claim 1, wherein each of said end panels includes a longitudinally extending medial portion of substantially lesser elasticity than its outer portions straddling said medial portion,
Claim 7
Dependent Claim
52 words
A surgical support according to claim 1, wherein each of said end panels is provided with outwardly converging longitudinal side edges such that each end panel is of lesser width at its outer end than said intermediate panel, and wherein opposing sections of each end panel are disposed in overlapping superimposed relationship.
Claim 8
Dependent Claim
82 words
A surgical support according to claim 1, wherein said fastening means comprises means forming a napped surface on one face of one of said end panels adjacent the outer end thereof, and a plurality of hook-shaped fiber members secured to and projecting from the opposing face of the other of said end panels adjacent the outer end thereof for grippingly engaging said napped surface on said one end panel to fasten together the distal ends of said end panels in overlapping relationship.
Claim 9
Dependent Claim
96 words
A lumbosacral surgical support comprising an elongate web comprising multiple plies of elastic textile fabric, a substantially rectangular core of resilient porous spongelike material sandwiched between and secured to medial portions of said plies and defining with the plies a semirigid intermediate support panel, said plies defining end panels extending outwardly from opposing side edges of said intermediate panel, said plies being interconnected along their opposing longitudinal side edges, and fastening means positioned on the distal ends of said end panels for securement of such ends together when the support is placed about a patient''s trunk.
Claim 10
Dependent Claim
96 words
A lumbosacral surgical support comprising an elongate web comprising multiple plies of elastic textile fabric, a substantially rectangular core of resilient porous spongelike material sandwiched between and secured to medial portions of said plies and defining with the plies a semirigid intermediate support panel, said plies defining end panels extending outwardly from opposing side edges of said intermediate panel, said plies being interconnected along their opposing longitudinal side edges, and fastening means positioned on the distal ends of said end panels for securement of such ends together when the support is placed about a patient''s trunk.
Claim 11
Dependent Claim
32 words
A surgical support according to claim 8, wherein said end panels are elastically Stretchable both longitudinally and transversely to readily conform to the physiognomy of the patient''s trunk in the lumbosacral region.
