  • Patent number: 10596051
    Abstract: The present invention relates to a system and method for sacral and trochanteric support and off-loading. The system provides a ultra low pressure plenum and a positioner. The patient body size and size and corresponding surface area of the positioner control the amount of gas which is displaced evenly against the walls of the ultra low pressure plenum to allow the combination of the ultra low pressure plenum and the positioner to slightly lift a patient from a bed surface, thereby offloading the sacrum and trochanter. The positioner can be an ultra low pressure bladder.

  • Patent number: 10363185
    Abstract: The present invention relates to a system and method for support and off-loading. The system includes an inner bladder filled with a flowable composition. An outer bladder filled with a flowable composition is positioned adjacent to the inner bladder. The composition of the inner bladder has greater flow characteristics than the composition of the outer bladder. The inner bladder micro-contours to the received body part and the outer bladder macro-contours to the inner bladder after the inner bladder is micro-contoured to the received body part. Alternatively, the system provides a pair of ultra low pressure plenums and a positioner. The patient body size and size and corresponding surface area of the positioner control the amount of gas which is displaced evenly against the walls of the ultra low pressure plenums.

  • Patent number: 10016326
    Abstract: The present invention relates to a support for a body part including a compression device in combination with a lower leg protection system. The compression device can be integral with the outer support at a position received over the lower leg. One or more valves can extend from a compression bladder for attachment to a pneumatic device. Inflation of the compression bladder positioner adjacent the lower leg also displaces air in the outer support toward the foot which causes simultaneous massaging of the foot. The pneumatic device can be adjusted to provide either sequential or intermittent therapies. The outer support can include a rigid outer shell for providing support.

  • Patent number: 9814642
    Abstract: The present invention relates to a mattress system in which a ultra low pressure plenum is positioned within the mattress system. In one embodiment, the ultra low pressure plenum is a bladder which is sandwiched between layers of a foam material. A plurality of ultra low pressure plenums formed as columns extending longitudinally or laterally along the length of the mattress system can be used.

  • Patent number: 9120666
    Abstract: The present invention provides a method and system for customization of flow characteristics of a support using permanent and controlled evacuation of interstitial gas during the manufacturing process. The flow characteristics can be customized to provide a stiffer or less stiff support by a comparative degree. The flow characteristics can be permanently changed. The support includes a bladder filled with a fluidized particulate material. The medium of the fluidized particulate material includes interstitial spaces. A predetermined amount of gas can be removed to provide a support having a desired specific support characteristic.

  • Patent number: 8858478
    Abstract: The present invention relates to a fluidized lower leg protection and support system and method. The system can include an inner positioner. The inner positioner can displace and contour three-dimensionally as though it was fluid to the sides and top of the leg while not having flow characteristics that would result in migration of the medium under the force of gravity. The system can also include an outer support which is received over the inner positioner. The outer support can be in the shape of an open boot. The outer support can include an ultra low pressure plenum. The ultra low pressure plenum is filled at a predetermined low pressure for distributing pressure along the length of the outer support, but not providing significant elevation of the lower leg and heel by itself.

  • Publication number: 20070083995
    Abstract: The present invention provides a fluidized positioning system including an inner bladder formed of a medium that has no memory or substantially no memory. An outer bladder is placed adjacent to or coupled to the inner bladder. The outer bladder is partially filled with a composition. The composition can be beads, such as polystyrene beads, or beads made of a similar medium. A valve extending from the outer bladder permits the evacuation of all or some of the air from the outer bladder which causes the outer bladder to be reduced in size due to loss of air between the beads and adjusts the rigidity of the outer bladder to allow the outer bladder to form fit the inner bladder around whatever body extremity it is being used on.
