Description
- This application claims the benefit of U.S. Provisional Application No. 61/755,460, filed on Jan. 22, 2013, which application is incorporated herein by reference.
- A preferred embodiment of a version of the invention refers to a manual and automatic, mechanically alternating air pressure relief apparatus and device for placement in wheel chairs and other seating apparatuses.
- The invention relates generally to cushions placed on a sitting apparatus, and particularly to a manual and automatic, mechanically alternating air pressure relief apparatus and device for placement in seating apparatuses. Users, particularly paraplegics, have experienced difficulty with circulation in the lower region of their bodies due to pressure from extended periods of sitting, to the point of suffering decubitus ulcers in the lower region of their bodies. Many patients are incapable of, or unsuccessful in, properly shifting their weight due to loss of sensation in the buttocks and the numerous weight shifts required per day. A means of manually or automatically periodically shifting pressure to different areas of the body would allow adequate blood flow, provide relief to users and prevent decubitus ulcers. This is especially useful to users who spend a significant amount of time sitting due to a handicap, such as users who utilize wheelchairs.
- Therefore, a need exists in the art for a manual and automatic air cell cushion device capable of alleviating the problems associated with long periods of sitting and immobility.
- Accordingly, a version of the invention is directed to a manual or automatic air cushion affixed to a sitting apparatus and preferably covering the horizontal surface of a sitting apparatus. The cushion can be quickly and easily placed on a sitting apparatus. The cushion is preferably controlled by a hand-held multifunction user interface, which can hang from the arm of a sitting apparatus when not in use. The control panel controls the timing of how pressure is to be relieved, through a rotation of inflation and deflation of multiple air chambers. The control panel will preferably control which air chambers are inflated, and when they are inflated. The control panel's keypad will preferably have a flat, easily cleaned surface with no cracks or crevices where food particles can become lodged, to prevent the spread of germs; and backlighting, similar to a telephone, for easy readability under all lighting conditions.
- The cushion may be made of flexible material with an airtight seal, such as plastic or rubber, to contain pressurized air. The cushion may be produced in different sizes to accommodate various sizes of sitting apparatuses. The bottom surface of the cushion may have a layer of gel to provide cushioning even when all air chambers are fully deflated. A multipurpose valve module may be contained within the cushion to electrically control and regulate airflow between the chambers.
- Additional features and advantages of the invention will be set forth in the description which follows, and will be apparent from the description, or may be learned by practice of the invention. The foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention.

Preferably, the connector has at least 9 feedline output ports 11. - In one embodiment of a version of the invention, there is provided an
electrical supply line 21 for providing power to air regulators and valves. In one embodiment, anelectrical supply line 21 provides power to individual port air regulators 12. In a preferred embodiment, amain supply line 41 powers acontrol device 20, thecontrol device 20 then provides individualpower supply lines 21 to each individualport air regulator 12. In a preferred embodiment, thecontrol device 20 will supply the necessary electrical current and signal to properly inflate/deflate eachindividual air cell 6. - In yet another embodiment of a version of the invention, the
multipurpose valve module 10 comprisesindividual air regulators 12 in contact with eachindividual air cell 6. - In one embodiment, the
valve module 10 will rotate inflation and deflation of the air chambers by unsealing and equalizing pressure between all air chambers, then sealing all air chambers and pumping air out of the chambers to be deflated, and into the chambers to be inflated. -
FIG. 3 andFIG. 4 show exemplary embodiments. In the first exemplary embodiment, arectangular air cushion 5 is provided. Theair cushion 5 is preferably composed of flexible material such as rubber, silicon or similar materials capable of an airtight seal to contain pressurized air. In a preferred embodiment of a version of the invention, the air cushion has twelvecircular air chambers 6 that are preferably one and one-half inches in diameter, and preferably about 2-4 inches deep. It is understood that the number ofair chambers 6, and size and shape ofair chambers 6 may be changed and altered and still fall within the scope of this invention. In one embodiment, theair chambers 6 are arranged in rows. Inflation and deflation of theair chambers 6 is rotated to provide periodic pressure relief to the user's lower region. More orfewer air chambers 6 are contemplated. The diameter and arrangement of theair chambers 6, and the dimensions of theair cushion 5 may also be adjusted. This adjustment may specifically accommodate the various sizes of sitting apparatuses currently available to the user. - While the foregoing written description of the invention enables one of ordinary skill to make and use what is presently considered to be the best mode thereof, those of ordinary skill in the art will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should, therefore, not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention.
