Abstract
Abstract A body-support floatation system comprising a reversible gelatinizing agent added to water within a flexible bladder. Further, a fungicide is added to the gel to inhibit bacterial growth which otherwise would cause deterioration of the gel. As the gelatinizing agent is reacted with the water, the mixture is aspirated so as to carry the mixing of the gelatinizing agent and the water to completion and, to entrap air in the gel to reduce the amount of gel required to fill the bladder, with a proportionate reduction in weight.

Claim 1
Independent Claim
116 words
A floatation system for supporting at least a portion of the human body, said floatation system comprising: a flexible enclosure; a gel-like substance encapsulating a plurality of air pockets within said enclosure for uniform distribution of body supportive forces by the floatation system, wherein said gel-like substance is water and a gelatinizing agent reversibly reactive with said water to form said gel, so that said gel-like substance is readily broken down into its original components, such agent being amoniated salt of Carbopol resin supended in a carrier, said Carbopol being of a weight between 0.15% and 0.30% of said water with which it is ultimately mixed; and a fungicide to prevent bacterial growth within said gel.
