Abstract
A patient support system has a first surface formed by one or more of a choice of structures. A fluidizable surface formed by air fluidizing a mass of fluidizable material is disposed adjacent the first surface. Examples of structures suitable for the first surface include a conventional mattress, with or without springs, polyurethane foam, and a plurality of inflatable sacks. The structure forming the first surface can be disposed on an articulatable member. The two surfaces are disposed end to end, and preferably the fluidized material supports at least the buttocks of the patient. the fluidizable material is laterally restrained by a member which is at least partially, vertically collapsible so as to facilitate the patient's ingress and egress to and from the support system. An interface member such as an inflatable sack, a non-rigid panel or a polyurethane foam member forms the part of the lateral restraint member which connects the two surfaces. The collapsible member can comprise an air impermeable panel which can form an inflatable elastic wall having one or more internal webs defining separately pressurizable compartments. A blower inflates the sacks, the elastic wall, and …
