Abstract: A mattress pad primarily intended for use with a standard hospital bed frame to reduce the development of decubitus ulcers or bed sores in patients using the pad. The pad is multi-layered and includes a cover or casing containing interior strata of a plastic film layer atop a fluid bladder layer supported on an underlying layer of foam. The pad is specially designed to reduce lateral and normal pressures and forces on the patient which can lead to the development of such ulcers. The reduction of the lateral shearing forces is accomplished in a number of ways including by oversizing the plastic film layer and fluid bladder layer on the underlying layer of foam and by positioning microbeads between the plastic film layer and fluid bladder layer to dramatically reduce the frictional drag or lateral shearing forces between the layers.

Abstract: A wheelchair back system is disclosed having a bolster with an improved mounting means. The bolster has a rear surface which is positioned on a lateral portion of the wheelchair back. A strap attached to the front surface of the bolster extends to and engages the front surface of the back, toward the center of the back. The strap provides the bolster with enhanced resistance to lateral forces which may be applied to the bolster during the use of the wheelchair.

Abstract: Disclosed is a wheelchair seat system which may be adapted to fit virtually any wheelchair frame and provides a high degree of adjustability in order to fit virtually any user and to achieve various therapeutically significant functions. Specifically, the wheelchair seat system of the present invention provides a seat which may be raised or lowered, pitched forwardly or rearwardly, rolled to one side or the other, and slide forward or backward to accommodate the wheelchair user's needs. Further, the seat system of the present invention provides for ready adjustments, and, at the same time, provides for easy disengagement and set-up of the seat system when it is desired to fold up the wheelchair for transport or storage.

Abstract: A wheelchair back system provides height adjustability of the back, adjustment of the tilt and a lumbar support for a user. The back system is removably-affixed to vertical wheelchair posts by pairs of upper and lower channels at the lateral edges of the back. One of the channels on each side is open to the rear and the other of said channels is open to the front, whereby the channels engage the wheelchair posts. A clip, affixed to the rear side of the wheelchair posts, releasably engages the front opening channels to secure the back in engagement with the wheelchair post.

Abstract: A customized seat cushion for the human body comprises securable, removable supports which are used in combination with a shaped tray and a pad containing a fluid filling material. In the preferred embodiment, the supports are fastened to selected contours of the shaped tray, and the surface presented by the supports and shaped tray are covered by the pad which is fastened to the exposed surfaces of the tray and pads to form a customized seat cushion.

Abstract: A light-weight, low-profile seat cushion is attached to a body engaging sling. The cushion includes a foam base having a dished out central portion, and an envelope, partially filled with fluid, positioned over the dished out portion of the base. In the preferred embodiment, a self-supporting back support is attached to the rear of the seat cushion.

Abstract: A hemorrhoid supporting pad assembly comprises a pad on a supporting surface which may be a seat cushion assembly. The pad is formed from a flexible envelope partially filled with a fluid. The pad is positioned on the supporting surface beneath a seated person. Lateral portions of the envelope containing the fluid extend beneath the seated person. The weight of the seated person causes the fluid in the lateral portions of the envelope to flow toward the central region of the envelope, where the fluid is forced upwardly, beneath the anus, to support the hemorroid.

Abstract: The present invention relates to a seat cushion for the human body which comprises a pad comprising a flexible envelope containing a fluid filling material, which pad is adapted to be used in combination with a shaped tray. In the preferred embodiment, the envelope of the pad is an extensible elastomeric material or the upper surface of the pad comprises excess material, and the pad is partitioned or segmented to limit the flow of the fluid filling material in selected areas of the pad.

Abstract: A hemorrhoid supporting pad, preferably associated with a seat cushion assembly, is formed from a flexible envelope partially filled with a fluid. The pad is positioned beneath a seated person. Portions of the envelope extend beneath the ischial tuberosities of the seated person, which causes the fluid in the envelope to flow into the central region of the envelope, where the fluid is forced upwardly beneath the anus to support the hemorrhoid.
