Patent number: 7434283Abstract: A mattress or another type of support surface which allows for discrete manipulation of the pressure on a supported body. The present invention includes resilient fluid cells having a spring bias, grouped to allow adjustable dynamic control of the pressure exerted on various locations of the body support. Each of the fluid cells has a multiple port air distribution system, either integral to the fluid cell or attached to the fluid cell. The multiple port air distribution system includes ports and allows for the control of intake flow, outflow, and sound. A harnessing system is attached to the ports of the multiple port air distribution system and interconnects the fluid cells in a pattern desired by the user. The harnessing system controls the directions and flow volume of air into the fluid cells creating selected zones. The harnessing configuration is customizable to a particular patient. The fluid cells are held together by a casing.Type: GrantFiled: February 11, 2005Date of Patent: October 14, 2008Assignee: M.P.L. LimitedInventors: John W. Wilkinson, John C. Wilkinson

Patent number: 6036271Abstract: A seating system is designed for self-adjusting pressure relief for use with wheelchairs and other generally confined seating arrangements. One or more support chambers filled with resilient foam and a fluid such as air are arranged on an upper support surface. A self-adjusting reservoir is provided and arranged in fluid communication with the chamber. A constant force spring cooperates with a pivoting plate arrangement and acts on the reservoir so as to balance fluid pressure between the reservoir and the support chamber with a patient received thereon. In some embodiments, three fluid/resilient foam chambers may be provided for independent operation with three respective adjustable reservoirs. In other embodiments, fluid filled chambers may be operatively associated with respective reservoirs and pivoting actuation plates specially adapted to fit below a wheelchair seat without interfering with the wheelchair support structure, or specially adapted to be carried in a pack on the wheelchair seat back.Type: GrantFiled: November 14, 1995Date of Patent: March 14, 2000Assignee: Span-America Medical Systems, Inc.Inventors: John W.

Patent number: 5699570Abstract: A pressure relief valve vent line mattress system utilizes a self-adjusting approach with a single air source to obtain in combination a low air loss feature for beneficial cooling and drying of a patient's skin. A single air supply source outputs a predetermined positive flow of air into one or more patient air support bladders. An air distribution manifold received within a mattress body receives and disperses overflow pressure routed thereto from the patient air support bladders via an air passageway having a first pressure relief valve with an established set point. A second pressure relief valve is associated with a pump return line adjunct to the constant air flow pump. The net effect is to disperse overflow pressure from the mattress bladders (tending to keep such bladders at a constant pressure) while providing low air loss through the mattress for patient cooling and drying effects, all utilizing a single air flow source.Type: GrantFiled: June 14, 1996Date of Patent: December 23, 1997Assignee: Span-America Medical Systems, Inc.Inventors: John W.
