  • Patent number: 5580504
    Abstract: A method of making a polyurethane foam mattress overlay so that it has several sections defined in a relatively flat support surface thereof. The sections are longitudinally disposed so as to correspond with different parts of a user's body. Each such section has predetermined support characteristics which are selected in relationship with such characteristics for the other sections so as to define systematized support. Specific numerical ranges and interrelationships for such sections are preferred. A plurality of projections are formed in each surface section. In general, the cross-sectional area of such projections at the overlay support surface or at a given depth therefrom is the same within each section, but differs from one section to another. Separation distances between such projections may also vary with the respective sections. The resulting tailored support characteristics in respective sections provide engineered support for all parts of a user's body.

  • Patent number: 4700447
    Abstract: A unitary support pad constructed of synthetic foam is described especially for use as a mattress pad for hospital patients. The pad has a number of discrete upstanding projections being independently compressible and formed in the pad so as to provide a generally flat surface with voids between the projections, preferably extending entirely through the pad, formed by compressing the foam, in discrete areas, which is severed as through the action of a transverse band saw while compressed.

  • Patent number: 4418514
    Abstract: A package for containing an orthopedic support constructed of open cell foam material may comprise a bag constructed of heat sealable thermoplastic multilayered film which is sealed along a single open edge after insertion of the orthopedic support therethrough into the bag. The orthopedic support is differentially compressed to such an extent as to reduce an irregular height dimension by a major amount with evacuation of a corresponding amount of air from the bag through the open edge prior to application of the heat seal along the open edge. An evacuated marginal portion of the bag extends outwardly about the orthopedic support by an amount corresponding to the reduction in height of the orthopedic support and results from the partial vacuum in the bag and the tendency of the open cell foam to rebound.

  • Patent number: 4210317
    Abstract: Apparatus is disclosed for properly supporting and positioning a patient's arm and shoulder when placed in a prone position on an operating table for laminectomy surgical procedures and the like after correct positioning of the spine is accomplished. The apparatus includes a resilient arm cradle having a trough which supports the arm distally from the shoulders to adjacent the patient's wrist which flexes to support the arm naturally bent and in which the weight of the arm is supported over a greater surface area in a manner which is particularly advantageous in preventing pressure points on the elbow. The apparatus further includes an axilla cuff which fits under the axilla and has an exterior contour which interfaces with the shape of the trough of the arm cradle in such a manner that a desired rotation of the shoulder is maintained so as to preclude brachial plexus damage.

  • Patent number: 4108170
    Abstract: A support strap for use in supporting a patient as when seated to prevent slumping of the patient as when the patient becomes drowsy. An elongated strap is employed which is preferably constructed of polyurethane and the like which has a substantial thickness and a width several times that of the thickness in order to afford a degree of yieldability. The opening formed by the strap is deformable but the strap is of sufficient width to prevent the strap from twisting. Since the strap possesses a substantial cross-sectional area, yielding under limited force to a certain extent is permitted while further yielding will be arrested. Lengths of Velcro fastening members are provided on opposite sides adjacent the ends of the strap permitting fastening of the strap about the body and a supporting member with sufficient adjustability to accommodate various sizes of patients to a variety of positions.
