Abstract
Abstract A support for pressure sore preventation in a patient such as a hospital or accident patient is made in one piece from plastic foam material and comprises a flexible support surface defined by a plurality of discrete elongate support elements defining the surface, the elements being spaced apart by elongate blind channels, wider at the base than at the surface, for promoting circulation of air adjacent to the support surface.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
204 words
A device for pressure sore prevention in a patient, comprising a generally rectangular block of resilient foam material defined by generally parallel and vertical head and foot ends, and generally parallel sides, said block having a main body portion with a plurality of substantially parallel elongate support elements projecting from one side thereof, said support elements being generally parallel with the sides of the block and extending from the head end of the block, to the foot end of the block, said support elements comprising respective flat-topped head portions of generally semi-elliptical cross-section and respective shank portions of narrower width than the corresponding head portions and joining the head portions to said main body portion, with adjacent support elements being spaced apart by elongate channels each including a narrow part open between the head portions of the adjacent support elements and a wider blind part of approximately elliptical cross-section undercutting the head portions of the adjacent support elements and of smaller width than the shank portions thereof, the support elements defining and extending continuously over a substantially flat resilient support surface effective to maintain interface pressure between the surface and a patient resting thereon sufficiently low as to prevent capillary occlusion in the patient.
Claim 2
Independent Claim
204 words
A device for pressure sore prevention in a patient, comprising a generally rectangular block of resilient foam material defined by generally parallel and vertical head and foot ends, and generally parallel sides, said block having a main body portion with a plurality of substantially parallel elongate support elements projecting from one side thereof, said support elements being generally parallel with the sides of the block and extending from the head end of the block, to the foot end of the block, said support elements comprising respective flat-topped head portions of generally semi-elliptical cross-section and respective shank portions of narrower width than the corresponding head portions and joining the head portions to said main body portion, with adjacent support elements being spaced apart by elongate channels each including a narrow part open between the head portions of the adjacent support elements and a wider blind part of approximately elliptical cross-section undercutting the head portions of the adjacent support elements and of smaller width than the shank portions thereof, the support elements defining and extending continuously over a substantially flat resilient support surface effective to maintain interface pressure between the surface and a patient resting thereon sufficiently low as to prevent capillary occlusion in the patient.
