Abstract
Abstract An incontinent care pad (10) having three layers and a method for making same. The top layer (11) provides a soft surface for patient contact. The second layer (12) provides a waterproof bottom. The third layer (13) comprises an absorbant inner material. The third layer connects to the first layer, but not to the second and the second layer connects to the first layer but not to the third.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
95 words
An incontinent care pad comprising: a top layer of soft liquid permeable non-abrasive material; a bottom layer of liquid repellant material secured about a substantial portion of the periphery thereof to said top layer; an inner layer of soft absorbent material having smaller lateral and longitudinal dimensions than said top layer, said inner layer being disposed directly between said top and bottom layers and attached to said top layer but not to said bottom layer whereby the inner layer can slide with respect to the bottom layer but not with respect to said top layer.
Claim 2
Dependent Claim
95 words
An incontinent care pad comprising: a top layer of soft liquid permeable non-abrasive material; a bottom layer of liquid repellant material secured about a substantial portion of the periphery thereof to said top layer; an inner layer of soft absorbent material having smaller lateral and longitudinal dimensions than said top layer, said inner layer being disposed directly between said top and bottom layers and attached to said top layer but not to said bottom layer whereby the inner layer can slide with respect to the bottom layer but not with respect to said top layer.
Claim 3
Independent Claim
135 words
A method of making an incontinent care pad, the method including the following steps: (a) step 1--the securement of an absorbant layer of material along the periphery thereof to a soft, non-abrasive layer of material, said absorbant layer having smaller lateral and longitudinal dimensions than said soft, non-abrasive layer; (b) step 2--the securement of a water repellent layer of material to said soft, non-abrasive layer about part, but not all, of the periphery thereof on the side of said soft, non-abrasive layer opposite said absorbant layer; (c) step 3--everting said soft, non-absorbant layer and said water repellant layer to thereby place said absorbant layer between said soft, non-abrasive layer and said water repellent layer; and (d) step 4--the securement of said soft, non-abrasive layer and said water repellent layer along the previously unconnected periphery thereof.
Claim 4
Independent Claim
135 words
A method of making an incontinent care pad, the method including the following steps: (a) step 1--the securement of an absorbant layer of material along the periphery thereof to a soft, non-abrasive layer of material, said absorbant layer having smaller lateral and longitudinal dimensions than said soft, non-abrasive layer; (b) step 2--the securement of a water repellent layer of material to said soft, non-abrasive layer about part, but not all, of the periphery thereof on the side of said soft, non-abrasive layer opposite said absorbant layer; (c) step 3--everting said soft, non-absorbant layer and said water repellant layer to thereby place said absorbant layer between said soft, non-abrasive layer and said water repellent layer; and (d) step 4--the securement of said soft, non-abrasive layer and said water repellent layer along the previously unconnected periphery thereof.
Claim 5
Dependent Claim
21 words
The apparatus of claim 1 wherein said inner layer connects to said top layer proximal the periphery of said inner layer.
Claim 6
Dependent Claim
22 words
The improvement of claim 3 wherein said top layer connects proximal the edges thereof to said bottom layer proximal the edges thereof.
