  • Patent number: 5651151
    Abstract: An alternating pressure pad has two sets of alternately inflatable cells. The alternately inflatable cells overlie additional base cells in a lower layer of the mattress. These base cells are all simultaneously inflated whilst each of the sets of upper cells are repeatedly inflated and deflated in alternation over an inflation and deflation cycle. During a cycle each set of upper cells is deflated at least once while the patient is primarily supported by the other inflated set of cells. During each inflation and deflation cycle, the additional base cells are reduced in pressure at least once. In this way, even if a part of the patient is temporarily supported only on the lower base cells, the support pressure is temporarily reduced each cycle to minimize pressure effects on the patient.

  • Patent number: 5632291
    Abstract: An air mattress for supporting an individual within a circular tent. The inventive device includes a circular upper web coupled to a circular lower web by a perimeter sidewall extending therebetween. An air valve is directed through the sidewall for permitting pneumatic inflation of the mattress. A plurality of spacing projections extend from the lower circular web and cooperate to support the mattress above a floor web of an associated tent.

  • Patent number: 5608931
    Abstract: Apparatus and method for controlling outward movement of flexible walls defining an enclosed chamber of a device inflatable by air or other compressible fluid, the outward movement occurring in response to application of an external force over portions of a flexible wall to decrease the volume and increase the internal pressure of the chamber. Spring-like couplings, preferably in the form of elastic members such as "rubber bands," are attached at spaced points to portions of the flexible, relatively moveable walls inside and/or outside the chamber. The couplings are so attached as to be expanded or stretched by relative movement of the flexible wall portions as the external force is applied, whereby the members exert a force resiliently opposing movement of the flexible walls in response to the increase in internal pressure caused by application of the external force.

  • Patent number: 5603131
    Abstract: A water filled mattress including a top sheet of flexible material that is capable of having a bottom sheet of flexible material joined by heat sealing. The top and bottom sheet are joined at their peripheries and form a waterproof enclosure. The waterproof enclosure is capable of retaining an amount of water. The waterproof enclosure has a circumferential border with a front end and a rear end. A plurality of heat welds intermittently join the top sheet and the bottom sheet to form a plurality of seams. Each seam is linearly aligned along the waterproof enclosure. Each seam ends at an identical distance. A headrest is formed within the waterproof enclosure adjacent the seam ending.

  • Patent number: 5581828
    Abstract: An airbed mattress assembly comprised of an air core disposed within a mattress cover, a layer of impact absorbing material with a thickness of from 0.5 to 1.5 inches contiguous with the bottom surface of the air core, an air blower having an intake to atmospheric air and having an exhaust to atmospheric air and having a pressurized air outlet, an air line connected to the pressurized air outlet and connected to the air core, an air valve, means for actuating the first air valve for opening air flow through said first air line and for simultaneously energizing the air blower, and means for actuating the air valve for opening air flow through the air line without simultaneously energizing the air blower. The air core has a depth from about 8 to about 12 inches, a length of from about 80 to about 84 inches and is formed from vulcanizing a multiplicity of sections of calendared material which comprises elastomeric material bonded to a fabric material.

  • Patent number: 5566409
    Abstract: A modular air mattress including three separate pieces, one to support the head region, the middle abdomen region, and the lower leg region of a human body, respectively. The mattress pieces include a low air loss ventilating air mattress piece and conventional, non-ventilating mattress pieces. The ventilating mattress piece is positioned to support a body region susceptible to bed sores, while the conventional mattress pieces are positioned to support non-bed-sore susceptible body regions. Each piece has means for releasably coupling to each of the other pieces so that the ventilating air mattress piece and conventional mattress pieces may be conveniently positioned, and securely coupled, in any longitudinal series. The releasable coupling means also facilitates easy and convenient replacement and/or rearrangement of the mattress pieces.

  • Patent number: 5561873
    Abstract: An inflatable flexible pallet having generally rectangular dimensions defined by top and bottom sheets within which an array of structurally interrelated inflatable chambers are formed to support a load when inflated. The flexible pallet is configured to resist lateral and longitudinal shrinkage of the load support surface, resist ballooning and hot dogging, and reduce rotational instability by providing a greater load surface support area having sufficient rigidity to support the desired load, while simultaneously achieving improved air dispersion for a more uniform jacking of the load, and maintaining a preset internal pressure using an automatic self-regulating valve to provide circulatory therapy to a patient lying atop the pallet for an extended period.

  • Patent number: 5560057
    Abstract: A turning air mattress serving to facilitate the therapeutic benefits of turning a bed ridden patient includes a combination of elongated transverse and longitudinal air cells disposed on a base and encompassed by a cell liner. The air cells are attached to a plurality of cell manifolds in communication with a control system. A top cover covering the air cells is attached to the base, and a fleece and top sheet are fittedly retained over the air cells.The control system having a microprocessor monitors the pressure within the air cells, along with overall system functions. The control system also enables a patient to be rotated from side to side, and leveled after being turned, in a smooth transition from a level position to a turned position, or from a turned position to a level position, while substantially maintaining spinal alignment.
