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.

An absorbent pad comprising:
- a) a first layer comprising a nonwoven material;
- and b) a base layer disposed under the first layer, the base layer comprising a breathable film;
- wherein the absorbent pad has a tensile strength at break, when measured by the ASTM D 882 method, in the range of 45 N/25 mm to 100 N/25 mm in the machine direction.
An absorbent pad comprising:
- a) a first layer comprising a nonwoven material;
- and b) a base layer disposed under the first layer, the base layer comprising a breathable film;
- wherein the absorbent pad has a tensile strength at 25% elongation, when measured by the ASTM D 882 method, in the range of 35 N/25 mm to 55 N/25 mm in the machine direction.
