Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
A therapeutic bed for reducing the effective weight of a human body and for uniformly supporting the entire length of the body, said bed comprising, a fluid-tight bed bath having a cavity therein defined by internal surfaces of said bed bath for the reception and containment of liquid; said internal surfaces of said bed bath surrounding said cavity being contoured, both horizontally and vertically, to conform approximately to the shape of a person who is to be placed on said bed; a fluid impervious, flexible sheet draped loosely over said cavity above the liquid to be received within said cavity; whereby said sheet maintains the person lying thereon in a state of dry flotation on the liquid contained within said cavity, and whereby the proximity of said internal surfaces defining said cavity to a body floating on said sheet materially reduces the amount of liquid necessary to float the body.
Claim 2
Dependent Claim
150 words
A therapeutic bed for reducing the effective weight of a human body and for uniformly supporting the entire length of the body, said bed comprising, a fluid-tight bed bath having a cavity therein defined by internal surfaces of said bed bath for the reception and containment of liquid; said internal surfaces of said bed bath surrounding said cavity being contoured, both horizontally and vertically, to conform approximately to the shape of a person who is to be placed on said bed; a fluid impervious, flexible sheet draped loosely over said cavity above the liquid to be received within said cavity; whereby said sheet maintains the person lying thereon in a state of dry flotation on the liquid contained within said cavity, and whereby the proximity of said internal surfaces defining said cavity to a body floating on said sheet materially reduces the amount of liquid necessary to float the body.
Claim 3
Dependent Claim
42 words
The therapeutic bed of claim 1, having a body positioned on the sheet thereof and floating over said liquid in said cavity; said body being spaced from said internal surfaces of said cavity by a distance ranging between 2 and 4 in.
Claim 4
Dependent Claim
29 words
The apparatus of claim 1 wherein said bed bath is constructed from a block of lightweight plastic material, the interior portion of which is removable to form said cavity.
Claim 5
Dependent Claim
12 words
The apparatus of claim 3 wherein said plastic material is foamed polystyrene.
Claim 6
Dependent Claim
27 words
The apparatus of claim 3 wherein said interior portion is removably replaceable in said cavity to form a flat surface upon which a body may be rested.
Claim 7
Dependent Claim
13 words
The apparatus of claim 1 wherein said bed bath is an inflatable tub.
Claim 8
Dependent Claim
34 words
The apparatus of claim 6 wherein said tub is comprised of a plurality of individually inflatable air chambers, one or more of which may be selectively inflated to vary the contour of said cavity.
Claim 9
Dependent Claim
35 words
The apparatus of claim 1, and further including a net draped over said cavity, said net having apertures on opposite sides thereof for the reception of rigid bars by which said net may be lifted.
