  • Inflatable decubitis mat with vent structures controlled by heat sensors
    Patent number: 7278179
    Abstract: A decubitis mat includes a plurality of individual cells (16 which are pressurized by air. A polymer sensor/vent structure (20) is mounted on the top surface of each cell and defines a plurality of polymer filled channels (28) and a vent valve (26) which is biased to a closed position. As a body resting on the mat heats the polymer, it undergoes a phase change an expands, causing biasing forces (30) which bias the vent valve to open, permitting air in the cell to be released providing air flow to the body.
