Abstract

An absorptive and protective patient underpad is characterized by its ability to absorb substantial volumes of liquid, while maintaining a relatively dry top surface and the underpad is further characterized by a layer between a top cushioning layer and a lower absorbent layer which will permit liquid flow into the absorbent layer and reduce to a minimum the generation and release of offensive odors from the absorbent layer.
