Abstract: A moisture drying mattress comprised of at least one cushion that has opposite top and bottom surfaces and a plurality of apertures that extend through the cushion from the bottom surface to the top surface. An air channel mat is positioned below the cushion. The air channel mat is adapted and dimensioned to fit beneath the cushion and support the cushion bottom surface in a spaced relation above a bottom base of the mat to thereby form an air flow space between the cushion and mat through which air can flow. A vapor permeable, liquid impermeable cover encases the air channel mat and the cushion defining a vapor evaporation area under the cover. The air channel mat defines a moisture drying zone within the vapor evaporation area. An air pump is provided for selectively supplying a flow of air to the air channel mat. A controller is provided to control the flow of air to the air channel mat to evaporate the vapor in the vapor evaporation area.

Abstract: A moisture drying mattress comprises a cover that encloses an air cell mattress and a plurality of air channel mats. The cover has a top portion that is vapor permeable and liquid impermeable. The air cell mattress has a plurality of apertures between the air cells. The plurality of air channel mats have a base and are positioned beneath the air cell mattress and within pockets located in the interior of the cover on a bottom portion of the cover. The air channel mats have a plurality of projections extending upwardly from the base that support the air cell mattress in a spaced relation from the air channel mat base. The air channel mats communicate with an air pump that is selectively controlled by a controller to selectively supply a flow of air to any of the air channel mats.

Abstract: A wheelchair back support assembly is both lightweight and sturdy, is designed to be inexpensively retrofit to an existing wheelchair of tubular frame construction, is designed to comfortably support the back of wheelchair user's of different sizes and having different physical characteristics and also flexes and moves relative to the wheelchair in response to movements of the back, shoulders and arms of the wheelchair user to thereby provide comfortable dynamic support to the back of the wheelchair user.

Abstract: A size-adjustable wheelchair seat comprises a first size-adjustable frame member, a second size-adjustable frame member and a cross frame member. The first frame member extends generally in a longitudinal direction. The first frame member includes a first penetrating frame element and a first receiving frame element. An end of the first penetrating frame element is telescoped within an end of the first receiving frame element. The second frame member is spaced laterally from and extends generally parallel to the first frame member. The second frame member includes a second penetrating frame element and a second receiving frame element. An end of the second penetrating frame element is telescoped within an end of the second receiving frame element. The cross frame element extends between the first frame member and the second frame member.

Abstract: A size-adjustable load supporting device comprising a load supporting top panel and a size-adjustable support frame. The support frame is adjustable laterally and longitudinally to fit a variety of wheelchairs and to accommodate different sized patients. The load supporting top panel is removably attached to the size-adjustable frame with VELCRO.RTM.. The support frame is comprised of four T-shaped components which are nestingly interfit with one another and slidable relative to one another to form a generally square support frame. With the top panel removed, the length and width of the support frame can be quickly adjusted by sliding the T-shaped components relative to one another to vary the amount of nesting. Once the support frame is adjusted to the desired size, the top panel is reattached, thereby securing the support frame. Four J-shaped brackets are provided, two on each side, to allow the device to be easily mounted on a standard wheelchair.

Abstract: A vacuum or heat formed cushion having upstanding cells of thin (15-40 mil) wall thickness and having rectangular body sections with upwardly inclined (10.degree.-40.degree.) triangular top panels. The cushions can be attached together to form a mattress or used individually as a wheelchair or other chair or back cushion. The cells of the cushion can all be interconnected or the cushion can be divided in two or more independently inflated compartments. A special wheelchair cushion has cells of different shapes, sizes and heights to promote positioning of a user on a wheelchair.The cushion has openings through the base to allow it to be placed on a manifold so that body fluids can drain away from the patient and conditioned air can be supplied to the patient.The top surfaces of the cells are textured to prevent sealing off the pores of the user's skin.
