  • Publication number: 20210113403
    Abstract: The present disclosure relates to a patient support which can be used in a bed or flat surface and in particular to a system and method for support and offloading of the body and for turning and repositioning of a patient in a bed or on a flat surface. Features of the disclosure also relate to markings and other indicators used on the patient support which help guide caregivers in the proper use and correct patient positioning on the patient support.

  • 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.

  • Publication number: 20150105707
    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.

  • Patent number: 8720721
    Abstract: A capless refueling system is provided which utilizes snap-in attachment of a multi-stage valve assembly within a fuel pipe. The valve assembly includes a lower body portion and a cover independent from the lower body portion. The lower body portion and the cover are configured to be lockingly adjoined to one another. The cover is adapted to be adjoined to the fuel pipe. The system is sealed at a position above the primary shutoff valve thereby eliminating the need for a spring pin support bracket.

  • Patent number: 8382188
    Abstract: The connection of a vehicle fuel fill system access door to an access door hinge includes exposed guide members on the access door and the hinge to assist an installer in properly positioning and moving the access door relative to the hinge. Spacing structures between the access door and the access door hinge have a variable relationship for accommodating part variations. An audible sound is generated as the door is connected to indicate final positioning of the door on the hinge.
