PATIENT SUPPORT

摘要

A patient support includes a cover and a compressible layer that includes air flow passages extending laterally, longitudinally, and transversely through the layer. The cover envelopes the compressible layer and forms a patient support surface thereon and further is adapted to be liquid impermeable, yet allow moisture vapor flow through the cover into the compressible layer and also allow moisture vapor flow out of the cover at a location other than the interface between a patient's body and patient support surface so that together the cover and the compressible layer will transport away moisture from the patient's body at the interface at the patient support surface and direct the moisture vapor to the location other than the interface at the patient support surface.
