ABSTRACT:
A patient support system has a fluidizable surface formed by air fluidizing a mass of fluidizable material. The fluidizable material is contained by a member which is at least partially collapsible so as to facilitate the patient's ingress and egress to and from the support system. 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. The fluidizable surface can be formed by a plurality of fluidizable cells disposed and attached atop an air permeable support. Each of these cells is detachably removable from the support for ease of cleaning and replacement. A blower inflates the sacks, the inflatable elastic wall embodiments and the fluidizable material via a network including manifolds, valves, and flexible tubing. A microprocessor controls actuation of the various valves and the blower according to signals inputted by operating personnel or supplied by various sensors which monitor the patient support system.
