Abstract

An inflatable cushion apparatus for maintaining a person'"'"'s lower leg, ankle and foot, in an elevated and substantially horizontal position relative to the person'"'"'s head and upper body. The inflatable cushion apparatus includes an angled front wall for supporting a person'"'"'s upper leg in an inclined position. A top wall is provided which extends horizontally when the apparatus is inflated. A valve is provided to facilitate filling of the cushion apparatus.

Claims

1. An inflatable cushion apparatus for supporting and maintaining a person'"'"'s lower leg, ankle and foot, in an elevated and substantially horizontal position relative to said person'"'"'s head and upper body and for supporting said person'"'"'s upper leg in an inclined position, said inflatable cushion apparatus being formed as an envelope portion, fabricated from substantially fluid-impermeable material, said envelope portion including a plurality of walls, operable assembled so as to be able to enclose and maintain a volume of fluid therewithin, such that said envelope portion, when so filled with fluid, is capable of supporting loads placed thereon, said inflatable cushion apparatus comprising:

a substantially rectangular bottom wall, having a leading edge and a rear edge;

a top wall, operable disposed to extend substantially parallel to said bottom wall when said envelope portion is inflated, and having a leading edge and a rear edge;

a back wall, operably disposed to extend from said rear edge of said bottom wall to said rear edge of said top wall;

a front wall, operably disposed to extend from said leading edge of said bottom wall upwardly, at an incline, to said leading edge of said top wall, said front and bottom walls thereby defining an acute included angle therebetween;

first and second side walls, operably disposed to connect said top, bottom, rear and front walls;

valve means, operably disposed in one of said walls, said valve means being operably openable and closable so as to enable said envelope portion to be filled when said valve is opened, and to retain its contents when said valve is closed;

horizontal partition means operably disposed within said envelope portion so as to divide said envelope portion into at least an upper and lower chamber,

said valve means comprising separate fluid filling means for each of said upper and lower chambers;

at least one padding member operably attachable to and removable from at least said top wall for providing further cushioning of said person'"'"'s leg; and

cooperating fastener means on each of said envelope portion and said at least one padding member, for removably attaching said at least one padding member to said top wall of said envelope portion,

2. The inflatable cushion apparatus according to claim 1 in which the invention further comprises:

said upper chamber having a height equal to or less than that of said lower chamber;

said upper chamber substantially fillable with a non-gaseous fluid, so that when said person'"'"'s lower leg is placed on said cushion apparatus, said non-gaseous fluid flows to enable said top surface to at least partially conform to said person'"'"'s lower leg.

3. The inflatable cushion apparatus according to claim 1, further comprising:

a retaining lip member operable disposed along said leading edge of said bottom wall for collecting and retaining fluid.

4. The inflatable cushion apparatus according to claim 1 in which said at least one padding member comprises an absorbent padding member operably attachable to and removable from at least said top wall for providing absorption of drainage from said person'"'"'s lower leg.

5. The inflatable cushion apparatus according to claim 1 wherein said cooperating fastener means for removably attaching said at least one padding member comprises:

buttons operably affixed proximate to said top wall of said envelope portion; and

buttonholes operably disposed in said at least one padding member for engagement with corresponding ones of said buttons.

6. The inflatable cushion apparatus according to claim 1 wherein said cooperating fastener means for removably attaching said at least one padding member comprises:

at least one corresponding pair of mated hook-and-loop fastener members,

at least one of said fastener members operably arranged on said envelope portion and configured to cooperate with at least another of said fastener members arranged on said at least one padding member.

7. The inflatable cushion apparatus according to claim 1, further comprising:

air pumping means, operably connectable to said valve means, for facilitated inflation of said envelope portion.

8. The inflatable cushion apparatus according to claim 1, wherein said fluid filling said upper chamber comprises:

a liquid, such as water.

9. The inflatable cushion apparatus according to claim 1, wherein said fluid filling said upper chamber comprises:

a gel.

10. The inflatable cushion apparatus according to claim 1 wherein said front wall and said bottom wall define an included angle therebetween of 45 degrees or less.

11. The inflatable cushion apparatus according to claim 1 wherein said at least one padding member comprises a removable cover member configured to insertingly receive said envelope portion.
