Abstract
Abstract The instant invention comprises a laminated cushioning means disposed between the skin of an amputee''s leg and the encompassing cupped wall of the appliance, the inner side of said means remaining soft, pliable and dry at all times while transferring latent moisture away from the skin of the amputee and storing same in spaced relation thereto and to said wall. Said means may be readily removed from the appliance as well as the stump and disposed of and replaced by a new one with the minimum of trouble and expense.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
81 words
A disposable stump sock composed of an inner tubular stumpshaped layer of hydrophobic paper closed at the bottom, open at the top and adapted to embrace the skin of an amputee''s stump, said hydrophobic paper layer being highly porous and being surrounded by a layer of absorbent material, and an outer layer of waterproof material surrounding said layer of absorbent material, whereby said inner layer will remain dry while transferring moisture from the skin of said stump to said absorbent material.
Claim 2
Dependent Claim
81 words
A disposable stump sock composed of an inner tubular stumpshaped layer of hydrophobic paper closed at the bottom, open at the top and adapted to embrace the skin of an amputee''s stump, said hydrophobic paper layer being highly porous and being surrounded by a layer of absorbent material, and an outer layer of waterproof material surrounding said layer of absorbent material, whereby said inner layer will remain dry while transferring moisture from the skin of said stump to said absorbent material.
Claim 3
Dependent Claim
25 words
The disposable stump sock of claim 1 in which said absorbent layer is adhesively attached to the outer side of said highly porous inner layer.
Claim 4
Dependent Claim
27 words
The disposable stump sock of claim 1 in which the inner hydrophobic layer is turned over and adhesively connected to the upper edge of said absorbent layer.
Claim 5
Dependent Claim
25 words
The disposable stump sock of claim 3 in which a stump-shaped layer of waterproof material frictionally engages said absorbent layer and is readily separable therefrom.
Claim 6
Dependent Claim
44 words
The disposable stump sock of claim 1 in which said inner layer is stump shaped and composed of an extremely thin and tough layer of hydrophobic porous paper to the outer side of which is adhesively attached a similarly shaped layer of absorbent material.
Claim 7
Dependent Claim
32 words
The disposable stump sock of claim 1 in which the stump-receiving lining is composed of a porous hydrophobic paper which is covered on one side by a pad composed of creped cellulose.
Claim 8
Dependent Claim
20 words
The disposable stump sock of claim 2 in which the absorbent material comprises a pad composed of creped cellulose wadding.
Claim 9
Dependent Claim
55 words
A disposable stump sock comprising a plurality of tubular layers of highly flexible paperlike materials which are adhered together, said layers being all open at the top and closed at the bottom, the outer layer of which is waterproof, the inner layer of which is hydrophobic and porous and the intermediate layer is highly absorbent.
Claim 10
Dependent Claim
55 words
A disposable stump sock comprising a plurality of tubular layers of highly flexible paperlike materials which are adhered together, said layers being all open at the top and closed at the bottom, the outer layer of which is waterproof, the inner layer of which is hydrophobic and porous and the intermediate layer is highly absorbent.
