Abstract
The present invention relates to a disposable sheet with an 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.
Claims21
A sheet adapted for covering a patient support structure comprising:
- a first layer having a perimeter and comprising:
- a flexible, fluid permeable, air permeable material, and
- an elastic cord joined to and extending along at least a portion of the perimeter of the first layer;
- a second layer having a perimeter and being disposed under the first layer, the second layer comprising at least one super absorbent material;
- a third layer having a perimeter and being disposed under the second layer, the third layer comprising a hydrophobic breathable film;
- and
- a fourth layer having a perimeter and being disposed under the third layer, the fourth layer comprising an air permeable material,
- wherein the perimeter of the first layer extends beyond the perimeters of the second, third and fourth layers along at least a portion of the perimeters of the second, third and fourth layers.
