초록 ▼

Pressure relief for wheelchair patients is improved by use of a relatively higher density foam, such as 2.4 pounds per cubic foot or above and a 25 percent ILD characteristic of at least about 50 pounds, together with independently acting cube shaped segments. The segments have predetermined respective separation and rounded upper edges with a predetermined radius of curvature which is larger about the periphery of the wheelchair pad. A relatively lowered pad thickness of about 3 inches facilitates patient movement onto and off from a wheelchair cushion. A removable covering of laminated materials is stretchable so as to slide over the rounded edges of the segments and down into separations therebetween to maintain independent action of such segments during use with the covering. An upper layer of the covering comprises a base layer of woven fabric of elastic synthetic fibers. A lower layer of the covering comprises a water resistant coating of urethane generally at least about 1 mil thick. The stretchable covering features can be used separately with other forms of patient supports, such as mattress pads having convolutions or other forms of independent support segments with separations therebetween.

대표청구항 ▼

An improved pressure relief support for use by a seated patient such as in a chair, comprising: a generally rectangular support pad comprised of resilient foam material, and having a predetermined thickness substantially in a range of from 5 to 10 centimeters, a generally planar bottom surface on one side thereof, and a plurality of generally cube shaped elements integrally formed with said pad on an opposite side thereof and defining a support pad upper surface, said cube shaped elements being respectively separated from adjacent such elements by a predetermined distance for relative independent movement thereof and having curved edges adjacent to said support pad upper surface which have a predetermined radius of curvature; and a removable elastic covering received over at least said support pad upper surface and stretchable at least part way into said element separations over said element curved edges whenever said pad is sat upon by a patient, said covering comprising a laminated construction of at least two layers, including a first layer turned generally away from said support pad and a second layer turned generally towards said support pad; wherein said covering first layer comprises an elastic synthetic layer which is relatively stretchable in at least one direction, said covering second layer comprises a generally water resistant coating of urethane applied to said first layer for stretching therewith, and said support pad resilient foam material has a density substantially in a range of from 2.4 to 3.0 pounds per cubic foot and a 25 percent ILD substantially in a range of from 50 to 60 pounds , where 25 percent ILD stands for 25 percent indentation load deflection, which is defined by the number of pounds of pressure required to push a 50 square inch plate into said support pad so as to compress same by 25 percent of its predetermined thickness.
