Abstract
Abstract Waterfloatation systems to prevent decubitus ulcers are known, but they suffer the disadvantages that systems having foam frames require a large volume for storage and transport. Modular systems which are very handy for hospitals normally are too expensive for home patients. This invention provides a floatation system having a foam frame which can be reduced to a very small volume and which can be used as a waterfloatation support for home patients at a considerably lower cost than conventional systems.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
91 words
A one piece, integral waterproof frame and basin apparatus for anti-decubitus waterfloatation comprising longitudinal side frame members fabricated of a highly compressible plastic foam material which is heat sealed into plastic side compartments each said compartment having at least one air escape opening to permit the compression of the foam frame members for storage and shipping, thereby reducing the total volume of the frame to a fraction of its uncompressed volume, and having a plastic bottom and end members forming, together with said frame members, said watertight frame and basin apparatus.
Claim 2
Dependent Claim
91 words
A one piece, integral waterproof frame and basin apparatus for anti-decubitus waterfloatation comprising longitudinal side frame members fabricated of a highly compressible plastic foam material which is heat sealed into plastic side compartments each said compartment having at least one air escape opening to permit the compression of the foam frame members for storage and shipping, thereby reducing the total volume of the frame to a fraction of its uncompressed volume, and having a plastic bottom and end members forming, together with said frame members, said watertight frame and basin apparatus.
Claim 3
Dependent Claim
77 words
The apparatus of claim 1 in combination with a water mattress made of a soft plastic material and having at least two independent compartments which are each equipped with a water valve, fitting snugly into said frame and basin, the two specific dimensions of the individual compartments of said mattress providing a choice as to water support for a bed-ridden patient, either head or body or both, corresponding to the degree of the decubitus-risk of said patient.
Claim 4
Dependent Claim
22 words
The combination anti-decubitus apparatus of claim 2 in which said frame and basin and said water mattress are fabricated in one piece.
