ABSTRACT:
This invention involves a multilayer low friction ambulatory pad for treating or preventing bedsores and pressure sores, and for managing fluids discharged from a person's body. The pad may have the form of a diaper with panels fittable to a person's body. The pad has a first slippery nonporous layer on which is a moisture absorbent second layer. A slippery, thin, porous third layer is on the second layer. The three layers are peripherally bonded to form a nonpenable seam which permits unbonded areas of the layers to slide slightly with respect to each other. The third layer may be sprayed with a filmy, dry, slippery fourth layer. A fifth layer of lubricating material which may be a microencapsulated lubricant or a free lubricant is applied to the third and fourth layers to form a very slippery top surface. The fourth and fifth layers do not clog the pores of the third layer to pass air and fluids to the absorbent second layer. In other pads, the absorbent layer is omitted. All pads can be shaped to fit various portions of a person's body to which the pads can be attached. The pads can be discarded after a single use.
