  • Patent number: 8468624
    Abstract: A multi-purpose air mattress apparatus is disclosed for use in at least a bed of a vehicle having an opposing pair of inwardly protruding wheel wells. The apparatus comprises, in one embodiment, an inflatable air mattress having a pair of opposing sidewalls, each defining a lateral recess sized for accepting at least a portion of the wheel wells therewithin and further defining recess ledges that selectively sit atop the wheel wells. With the apparatus positioned within the vehicle bed and the wheel wells positioned at least partially within the lateral recesses, the recess ledges in combination with a perimeter ledge cover substantially any exposed portions of the wheel wells, while a set of upper and lower perimeter chambers further maintain a stable structure of the apparatus during use both within a vehicle bed as well as on any other relatively flat surface in otherwise conventional fashion.

    Abstract: A method and apparatus for coupling and decoupling an air supply hose to an inflatable device. The inflatable device may be adapted to support a patient, such as an air mattress or an inflatable patient transfer mat that rides on an air cushion. The method and apparatus utilize an air inlet that normally assumes a flat orientation. The air inlet includes resilient members that allow the air inlet to flex out of the flat orientation in response to a compressive force. The compressive force changes the air inlet's orientation into a generally round orientation that is sized to accept an air supply hose. A collar on the air supply hose is able to frictionally engage an edge in the air inlet in order to prevent undesired removal of the hose from the inlet. Magnets may be used to help return the inlet to the flat orientation when not in use.

The crib surrounds the perimeter of the fluid bladder system and the cover overlies the top surface of the crib and fluid bladder system. The fluid bladder systems provide at least one conventional bladder therapy to a patient positioned on the mattress system. The fluid bladder system interconnects to the crib to not form a hammock effect so the crib functions as a restraint. The fluid bladder is also designed to bottom out to form an exterior cavity. A second cushion is inserted into the exterior cavity and positioned so the crib continues to function as a restraint. The second cushion provides a therapy to the patient that is different from the fluid bladder system.

  • Publication number: 20120036645
    Abstract: An inflatable bed includes a bedstead assembly, a mattress assembly, and an electrical air pump unit. The mattress assembly is disposed on and above the bedstead assembly, and includes a top sheet, a bottom sheet disposed under the top sheet, and a plurality of surrounding sheets interconnecting the top and bottom sheets to form a plurality of air chambers, which are not in fluid communication with each other. Each of the air chambers is defined among the top sheet, the bottom sheet, and a respective one of the surrounding sheets. The electrical air pump unit is disposed on the bedstead assembly, and is operable to inflate the air chambers individually so that air pressures in the air chambers may be different.

  • Patent number: 8104125
    Abstract: A self-contained gatching mattress is provided having a gatching mattress sleep deck, a first air bladder cushion, a second cushion material, a control box having an air pump system and a manifold, a conduit distribution unit, a sliding bridge, and a cushion material positioned above the sliding bridge and the control box. The sliding bridge forms a gap area for conduits to extend from the control box to the conduit distribution unit which decreases the chances of the conduits being kinked or the conduits altering the cushion's tissue interface pressure to a patient positioned on the cushion when the sleep deck is gatched and/or portions are retracted or extended.

  • Patent number: 8087113
    Abstract: An alternating pad comprises a first set and a second set of alternately inflatable cells. Both sets of inflatable cells are supplied with air from a pump via a rotary valve. A sensor is positioned under the pad to receive pressure exerted by a patient upon movement and to be compressible relative to the applied pressure. Any change in patient position or movement will cause an alteration in the airflow in the sensor pad tube and will reduce or increase the differential pressure measured at the pressure transducer. Based on this feedback the microprocessor directly controls the power level to the pump and increases or decreases the air flow to the cells to alter the amplitude of the cells and also controls the timing of the rotary valve to change the timing of the inflation and deflation cycle.
