Hybrid air immersion mattress

Abstract

The hybrid air immersion mattress is a non-powered complete support system using an adjustable zoned air/foam filled cells and self inflating automatic pressure relief system that surrounds the patient and conforms to an individual's shape to provide skin/soft tissue injury protection and assist in wound healing providing greater immersion and comfort. The air/foam filled cells conform to an individual's shape to provide skin/soft tissue injury protection and assist in wound healing. The air immersion mattress stimulates a fluid environment which enhances the prevention and management of pressure ulcers, skin flaps, and grafts. The hybrid air immersion mattress is designed for comfort and enhanced circulation utilizing adjustable air bladders together with high density support foam. The apparatus includes a low friction mattress cover top, memory foam topper, mattresses air bladder containing air and foam elements, foam foundation, mattress bottom, inflation valve for the bolsters, and adjustable valves for the air bladders.

I claim: 
     
         1 . A hybrid air immersion mattress, comprising:
 a base pad comprising a high density foam pad enclosed by a fire sock;   an inflatable air bladder assembly consisting of a plurality of high density foamed filled inflatable cross member cells comprising a gas impermeable polymer supported by said base pad, at least some of said inflatable cross member cells including air bladder hook and loop material adhering to a top surface thereof;   an inflatable left bolster and an inflatable right bolster supporting said plurality of high density foamed filled inflatable cross member cells disposed therebetween supported by said base pad;   a top pad comprising a high density visco elastic foam including a top cover comprising a low friction silicone sheet connecting to a stretchable fabric covering a bottom surface of said top pad and said bottom surface of said sleeve having spaced apart patches of top pad hook and loop material adhering thereto for cooperative engagement with said air bladder hook and loop material; and   a cover comprising a top sheet of stretchable air permeable fabric connecting to a vinyl bottom sheet of material connecting thereto by a zipper.
