Abstract
Abstract Disclosed herein is a disposable, foldable and inflatable protective sleeve for a conventional, re-usable, rigid splint board. The sleeve comprises three juxtaposed sheets of thermoplastic material fastened together to form two expansible pockets. One of the pockets is provided with an opening for insertion of the rigid splint board to provide a sanitary splint to support, in an immobile position, the limb of a patient. A valve is associated with the other of the pockets so that it may be inflated to provide a yieldable, cushion-like surface between the splint and the limb for maximum patient comfort. Advantageously, the inflated pocket will apply a stretching force to the first pocket to retain the rigid splint board securely therein. Prior to use, the protective sleeve is compactly foldable for convenient, sanitary storage. The disclosed structure affords easy insertion of a conventional splint board and subsequent inflation for a highly effective limb support. After use, the sleeve is disposable.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
179 words
A foldable, disposable, inflatable protective sleeve for use in association with a re-usable, rigid splint board, which comprises (a) three rectangular sheets of thermoplastic material each being formed to be slightly in excess of the rigid splint board width and length dimensions and being arranged and configured in juxtaposed layers comprising two outer sheets and one intermediate sheet, (b) fastening means to form an air-tight seal between the three juxtaposed sheets at the peripheral portions thereof, (c) a first expansible pocket defined by the air-tight seal, one of said outer sheets and the intermediate sheet, (d) a second expansible pocket defined by the air-tight seal, the other of said outer sheets and the intermediate sheet, (e) an access slot being formed in said first pocket, (f) said rigid splint board being insertable into the first pocket through said access slot, and (g) selectively operable valve means associated with said second pocket whereby pressure fluid may be admitted to said second pocket, thereby inflating the second pocket to provide a yieldable, pillow-like supporting surface over the inserted rigid splint board.
Claim 2
Dependent Claim
179 words
A foldable, disposable, inflatable protective sleeve for use in association with a re-usable, rigid splint board, which comprises (a) three rectangular sheets of thermoplastic material each being formed to be slightly in excess of the rigid splint board width and length dimensions and being arranged and configured in juxtaposed layers comprising two outer sheets and one intermediate sheet, (b) fastening means to form an air-tight seal between the three juxtaposed sheets at the peripheral portions thereof, (c) a first expansible pocket defined by the air-tight seal, one of said outer sheets and the intermediate sheet, (d) a second expansible pocket defined by the air-tight seal, the other of said outer sheets and the intermediate sheet, (e) an access slot being formed in said first pocket, (f) said rigid splint board being insertable into the first pocket through said access slot, and (g) selectively operable valve means associated with said second pocket whereby pressure fluid may be admitted to said second pocket, thereby inflating the second pocket to provide a yieldable, pillow-like supporting surface over the inserted rigid splint board.
Claim 3
Dependent Claim
29 words
The protective sleeve according to claim 1, further characterized by (a) said fastening means comprising a heat seal formed at the outer perimeter of the three juxtaposed thermoplastic sheets.
Claim 4
Dependent Claim
28 words
The protective sleeve according to claim 1, further characterized by (a) said valve means comprising a plastic two-way valve mounted to the outer sheet defining said second pocket.
Claim 5
Dependent Claim
37 words
The protective sleeve according to claim 1, further characterized by (a) said sheets being formed to have dimensions slightly in excess of the width and length dimensions of a splint board arranged to support a human arm.
Claim 6
Dependent Claim
37 words
The protective sleeve according to claim 1, further characterized by (a) said sheets being formed to have dimensions slightly in excess of the width and length dimensions of a splint board arranged to support a human leg.
Claim 7
Dependent Claim
267 words
A foldable, disposable, inflatable protective sleeve for a re-usable, rigid splint board, which comprises (a) three rectangular sheets of thermoplastic material each being formed to be slightly in excess of the rigid splint board width and length dimensions and being arranged and configured in juxtaposed layers comprising two outer sheets and one intermediate sheet, (b) fastening means to form an air-tight seal between the three juxtaposed sheets at the peripheral portions thereof, (c) a first expansible pocket defined by the air-tight seal, one of said outer sheets and the intermediate sheet, (d) a second expansible pocket defined by the air-tight seal, the other of said outer sheets and the intermediate sheet, (e) an access slot being formed in said first pocket for insertion of said rigid splint board, and (f) selectively operable valve means associated with said second pocket whereby pressure fluid may be admitted to said second pocket, thereby inflating the second pocket to provide a yieldable supporting surface, (g) said fastening means comprising a heat seal formed at the outer perimeter of the three juxtaposed thermoplastic sheets, (h) said heat seal being formed in a spaced, parallel relation to the side edges of the sheets to form wing flap portions along the sides of said protective sleeve, (i) a plurality of slot openings formed in said wing flaps, and (j) a plurality of supporting straps whereby after insertion of said rigid splint board into said first pocket and inflation of said second pocket, said straps may be laced through said slot openings to attach said protective sleeve and rigid splint board to a patient's limb.
