Abstract

Abstract Cushions and cushion arrangements for preventing and alleviating bedsores comprising a cushion structure including a casing having a porous upper portion of artificial sheepskin or similar material, a resilient cushion within the casing, means for supplying temperature-controlled air to the casing, and means within the casing for directing the air so as to cause it to pass through the porous upper portion of the casing, over substantially the entire area thereof, into contact with the body of the user.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 124 words
A body cushion for use in the prevention and alleviation of bedsores, comprising: a. a casing comprising upper and lower portions forming an enclosure, at least said upper portion being formed of a porous material, b. a resilient pad substantially filling said casing, c. a relatively thin sheet non-porous of material having at least one surface with substantially parallel spaced grooves formed therein, said sheet overlying said pad with said grooved surface facing said porous portion of said casing and being substantially coextensive therewith, and d. means for supplying air to said casing under pressure to cause said air to pass through the grooves in said sheet and emerge from said casing over substantially the entire area of the porous portion of said casing.
Claim 2
Dependent Claim 124 words
A body cushion for use in the prevention and alleviation of bedsores, comprising: a. a casing comprising upper and lower portions forming an enclosure, at least said upper portion being formed of a porous material, b. a resilient pad substantially filling said casing, c. a relatively thin sheet non-porous of material having at least one surface with substantially parallel spaced grooves formed therein, said sheet overlying said pad with said grooved surface facing said porous portion of said casing and being substantially coextensive therewith, and d. means for supplying air to said casing under pressure to cause said air to pass through the grooves in said sheet and emerge from said casing over substantially the entire area of the porous portion of said casing.
Claim 3
Dependent Claim 18 words
A body cushion according to claim 1 in which said upper casing portion is made of artificial sheepskin.
Claim 4
Dependent Claim 70 words
A body cushion according to claim 1 of a size and form to be placed under the body of the user extending from the region of the buttocks to the region of the shoulders, in which said resilient pad is tapered in thickness longitudinally to provide a relatively thick portion in the region of the buttocks and a relatively thin portion in the region of the shoulders of the user.
Claim 5
Dependent Claim 54 words
An arrangement of body cushions comprising a pair of elongated cushions according to claim 1 adapted to be placed under either side of the body of a user extending from the region of the buttocks to the region of the shoulders and leaving the central spinal portion of the body of the user unsupported.
Claim 6
Dependent Claim 21 words
An arrangement according to claim 4 including spacing means interconnecting the pair of cushions to maintain a desired separation between them.
Claim 7
Dependent Claim 19 words
A body cushion according to claim 1 including means for controlling the temperature of air supplied to said casing.
Claim 8
Dependent Claim 50 words
An arrangement of body cushions comprising a plurality of cushions according to claim 1 adapted to be placed in spaced adjacency to a region of the body of the user susceptible to formation of bedsores so as to support the body in that region without directly contacting the susceptible region.
Claim 9
Dependent Claim 38 words
An arrangement according to claim 7 in which said cushions are tapered to provide maximum thickness in the portions thereof adapted to engage the body in the immediate vicinity of the body region susceptible to formation of bedsores.
Claim 10
Dependent Claim 177 words
A body cushion for use in the prevention and alleviation of bedsores, comprising: a. a casing comprising upper and lower portions forming an enclosure, at least said upper portion being formed of a porous material, the edges of said portions being provided with relatively airtight but readily separable seals to permit convenient access to the interior of said casing, b. a resilient pad within said casing and substantially coextensive with the lower portion thereof, c. a relatively thin sheet of material overlying said resilient pad, substantially coextensive therewith and having substantially parallel spaced grooves formed in its upper surface, d. a plurality of smaller movable resilient pads interposed between said grooved surface of said sheet and the upper portion of said casing so as to be adjustable in position to provide additional support for particular body regions, and e. means for supplying air to said casing under pressure to cause said air to pass through the grooves in said sheet and emerge from said casing over substantially the entire area of the porous portion of said casing.
Claim 11
Dependent Claim 177 words
A body cushion for use in the prevention and alleviation of bedsores, comprising: a. a casing comprising upper and lower portions forming an enclosure, at least said upper portion being formed of a porous material, the edges of said portions being provided with relatively airtight but readily separable seals to permit convenient access to the interior of said casing, b. a resilient pad within said casing and substantially coextensive with the lower portion thereof, c. a relatively thin sheet of material overlying said resilient pad, substantially coextensive therewith and having substantially parallel spaced grooves formed in its upper surface, d. a plurality of smaller movable resilient pads interposed between said grooved surface of said sheet and the upper portion of said casing so as to be adjustable in position to provide additional support for particular body regions, and e. means for supplying air to said casing under pressure to cause said air to pass through the grooves in said sheet and emerge from said casing over substantially the entire area of the porous portion of said casing.
Claim 12
Dependent Claim 40 words
A body cushion according to claim 9 in which the edges of the upper and lower portions of said casing are provided with separable fasteners permitting access to the inside of said casing for adjustment of said movable resilient pads.
Claim 13
Dependent Claim 25 words
A body cushion according to claim 8 in which said air supplying means comprises means for supplying air to said cushion at opposite ends thereof.
Claim 14
Dependent Claim 13 words
A body cushion according to claim 1 having the form of an annulus.
