Abstract
The present invention relates to a disposable absorbent pad comprising multiple layers. In particular, the absorbent pad of the present invention maintains skin dryness by absorbing moisture while preventing leakage to the skin or the bed linens, allowing air circulation at the surface of the patient's skin to prevent heat buildup, and is strong enough to allow the patient to be repositioned, even when the pad is wet. In a particular embodiment the first layer is comprised of a fluid-permeable, porous material, the second layer is disposed under the first layer and is comprised of at least one super absorbent material, and a base layer disposed under the second layer.
Claims44
An absorbent pad comprising:
- a) a first layer which is fluid permeable and air permeable;
- b) a second layer disposed under the first layer, comprising at least one super absorbent material;
- c) a base layer disposed under the second layer, comprising a hydrophobic breathable film disposed over an air-permeable material, wherein the tensile strength of the base layer at break, when measured by the ASTM D 882 method, is in the range of about 45 to about 100 N/25 mm in the machine direction and about 30 to about 60 N/25 mm in the cross direction, wherein the base layer comprises:
- d) a third layer disposed under the second layer, comprising a hydrophobic, breathable film;
- and e) a fourth layer disposed under the third layer, comprising an air-permeable material.
