  • Patent number: 11116326
    Abstract: An endoskeleton elastomer that variably impacts the mattress firmness head-to-toe is described. The elastomer fills voids cut into the foam using contour cutting or spherical cap-shaped cutouts. The elastomer is poured as a hot liquid into the voids, and cools to a solid elastomer. The specific incarnation involves the creation of a set of parallel inclusions at the center of the mattress or a set of spherical cap-shaped cutouts that help prop up the hip area to maintain proper spinal alignment by firming the center of the mattress. The depth, width, shape, spacing, elastomer durometer, and location (both head-to-toe and depth in the mattress) may be varied to impact firmness in any desired manner. The mattress may also include a series of horizontal-oriented cutouts that are cut into various portions of the mattress layers. These cutouts may extend along the width of the mattress and may be placed at portions of the top and portions of the bottom of the mattress.

  • Patent number: 10335335
    Abstract: For each air cell, air is supplied and discharged through one of three lines independent of one another, every third cell being connected to the common line. The control unit controls inflation and deflation of air cells in turn in such an alternate manner that first the pressure of air in the air cells on the first line is increased and decreased, secondly the pressure of air in the air cells on the second line is increased and decreased, then the pressure of air in the air cells on the third line is increased and decreased. Thereafter, when the back tilt angle of the back bottom has reached a predetermined angle or greater, the control unit increases the pressure of air cells whose pressure is being lowered at that moment so as to produce an inflated mode similar to that of the other air cells. Then, while the back bottom is being raised, the control unit performs an inflation and deflation control of individual lines alternately on a cycle shorter than that in a normal control mode.

  • Patent number: 9277829
    Abstract: A method for monitoring pressure at one or more points on an individual and automatically adjusting one or more sections of a support structure. The method includes periodically receiving pressure data from one or more radio frequency addressable sensors placed on an individual; determining, based on the received pressure data, whether an adjustment in the support structure is required; systematically adjusting cells located within the plurality of zones, one zone at a time, until an improvement in pressure data is indicated. If an improvement in pressure data is indicated for a zone, systematically adjusting cells within the plurality of subzones for that zone, one subzone at a time, until an improvement in pressure data is indicated. If an improvement in pressure data is indicated for a subzone, systematically adjusting cells in that subzone, one cell at a time, until an improvement in pressure data is indicated.

  • Patent number: 9265352
    Abstract: A sleeping system is described in which comfort systems for a foam mattress assembly are mounted in a foundation assembly supporting the mattress assembly. The comfort systems include an air heating and cooling system, a firmness system and an elevation system. The foam mattress assembly includes a flexible encasement dish into which one or more foam layers are disposed. Blowers for the air system are mounted adjacent the foundation assembly top in direct fluid communication with apertures in the top, minimizing the air flow path from the blower exhaust to the mattress top to reduce air pressure loss and diminishment of the heated or cooled air.

  • Patent number: 9205011
    Abstract: A pneumatic mattress (1) has two edge cells (2,3) and a even plurality of transverse inner cells, arranged in adjacent pairs as alternate cells (4) and cells (5). An umbilical inflation hose (6) is provided with three internal pipes (7,8,9). Pipe (7) receives constant pneumatic pressure and has a pipe extension (17) to pneumatic connectors (27) for the edge cells (2,3). Pipe (8) receives alternating pressure for cells (4) via extensions (18) to connectors (28). Pipe (9) receives alternating pressure for cells (5) via extensions (19) to connectors (29). The connectors (28,29) are T connectors having a stem welded into the bottom of their cells (4,5). The connectors (28,29) are in lines (38,39). Each cell has a connector at both ends, whereby there are lines (38 & 39) at both sides of the plurality of inner cells (4,5). The edge cells (2,3) are formed by folding and seaming a sheet of polyurethane material leaving a pair of strips (11) on top of each other.

  • Patent number: 9192533
    Abstract: A patient positioning wedge, mattress, pillow, pod, or other surface or apparatus for preventing or relieving pressure ulcers or other types of wounds through low air loss therapy, alternating pressure therapy, or both, and the ports, controllers, and manifolds used in combination. The mattress includes a plurality of perforated or otherwise porous air cells for supporting the patient's body weight. The mattress further includes valves and accessory ports to pump air into accessories, such as patient positioning wedges, pods, and pillows. Each accessory also includes perforated or otherwise porous air cells. The air cells in the mattress and accessories allow for low air loss therapy and/or alternating pressure therapy by passing air between the contact surface of the mattress or accessory and the contact surface of the patient, thus helping alleviate pressure, heat, friction, and moisture, while maintaining support and stability of the patient.
