  • Patent number: 9439822
    Abstract: A lifting assembly includes a pillow that may be positioned between a user and a support surface after the user has fallen onto the support surface. The pillow may support a weight ranging between approximately 250 pounds and 500 pounds. A valve is attached to the pillow and a pump is selectively attached to the valve. The pump selectively urges air into the pillow thereby facilitating the pump to inflate the pillow. The pillow lifts the user upwardly from the support surface as the pillow is inflated thereby facilitating the user to stand up. The pillow reaches a height ranging between approximately 18 inches and 25 inches with respect to the support surface when the pillow is inflated.

    Abstract: An air delivery system that includes an inflatable cushion device adapted to support at least a portion of a body of a user. The air delivery device includes a supply conduit in fluid communication with both an interior region of the inflatable cushion device and a controller. Using a pressure sensor, the controller is adapted to relatively continuously measure a static air pressure level of the interior region and compare the measured static air pressure level to a target air pressure level. Further, the controller is adapted to intermittently operate an air pump. Moreover, the controller may operate the air pump when measured static air pressure is below the target static air pressure level, and deactivate operation of the air pump, which may include maintaining the air pump in an un-operated condition when the measured static air pressure is within the target static air pressure level.

  • Patent number: 8904584
    Abstract: A cellular cushioning system includes cells or support units arranged in one or more stacked arrays. The cells are hollow chambers that resist deflection due to compressive forces, similar to compression springs. The arrays are attached to one or more intermedial binding layers. The intermedial binding layer(s) links the cells together while allowing the cells to deform independently of one another. An external load compresses of one of the void cells within an independent compression range without significantly compressing at least one void cell adjacent the compressed void cell. The independent compression range is the displacement range of the compressed void cell that does not significantly affect the compression of adjacent void cells. If the void cell is compressed beyond the independent compression range, the intermedial binding layers may be deflected and/or the void cells adjacent the compressed void cell may be compressed.

  • Patent number: 8732877
    Abstract: A body support system for relieving contact pressure on a joint in a body, according to various aspects of the present invention, may be configured to elevate a chest portion of the body with a chest support that may be configured to form a taper disposed between a top portion and a bottom portion such that the weight of the body compresses the chest support, which may result in the chest support assuming a substantially inverted arc shape. The compressed edges of the arc may be occupied by the joint. The chest support may further be adjustable for positioning substantially between a collarbone portion of the body and a xiphoid process portion of the body when the body is in a side rest position.

  • Patent number: 8734372
    Abstract: A traction device comprises a frame, a first bladder portion, a second bladder portion, a strap, and a pump. The first bladder expands in an outward direction a distance greater than in a transverse direction. The second bladder expands in an angular direction. The second bladder is positioned generally below and to the side of the first bladder. The frame is secured to the user's head. Upon expanding in the outward direction, the first bladder bears against the back of the user's neck and forces the cervical spine to curve forwardly. Upon expanding in the transverse direction, the first bladder applies an angular traction to the cervical spine. Upon expanding in the angular direction, the second bladder bears angularly against the back of the user's upper thoracic region and forces the thoracic spine to decompress and reduces hyper-kyphosis of the upper thoracic spine.

  • Patent number: 8719983
    Abstract: An inflatable body contour support cushion comprises a bladder comprising a flexible material. Said bladder is configured to retain a quantity of material to maintain said bladder in a flaccid state in which the material flows freely within said bladder. Said bladder is further configured to support a body contour by filling the space between the body contour and a surface against which the body contour is resting. A valve mechanism is configured to enable addition and removal of the material from said bladder in which a user can adjust a level of the support.

  • Patent number: 8720120
    Abstract: The present invention is related to inflatable devices, and, more specifically, to inflatable devices in combination with rigid surfaces and a method for deflating an inflatable device. According to one embodiment of the present invention an inflatable device is provided. The inflatable device includes a substantially fluid impermeable bladder and an outlet in the bladder. The inflatable device also includes a first substantially rigid surface in contact with a first surface of the fluid impermeable bladder and a second substantially rigid surface in contact with the first surface of the fluid impermeable bladder. In this embodiment, the first and second substantially rigid surfaces collectively are in contact with more than half of the first surface of the fluid impermeable barrier. According to another embodiment of the present invention, a method of deflating an inflatable device is provided.

  • Patent number: 8683632
    Abstract: An internal valve (10, 10? or 10?) and its methods of use for stabilizing and reinforcing inflatable objects are disclosed. The internal valve is a novel, simple modification to conventional check valves with the addition of a discharging means (14, 22 or 28)for external control. An internal supplemental chamber comprises one or more partitions that are secured, directly or by I-beams (40?), to main chamber's walls (40) of an inflatable object and stretched when the main chamber is inflated. With the internal valve as the passage to and from the main chamber, the enclosed or isolated supplemental chamber (30, 30?, 32, 34, 36 or 38) functions as a stabilizing or reinforcing component. A plurality of chambers 36 can form cylinder beams for an inflatable mattress.

  • Patent number: 8678007
    Abstract: A patient support system for a wheelchair is provided. At least a portion of the patient support system components form a no-air-loss patient support surface. At least one fluid pump can supply air pressure to a plurality of no-air-loss air cells, and at least one pressure release valve can release air pressure from the no-air-loss air cells. A computer can compare air pressure within the air cells to a desired air pressure set point and can modulate the air pressure by actuating the at least one fluid pump and/or the at least one pressure release valve to bring the air pressure within the air cells to a desired air pressure. After the initial air pressure adjustments are made and the desired air pressure is achieved, no further adjustments during the operation are able to be made by the computer so that the patient positioned thereon the patient support system will not be moved by the patient support system during an operation.

  • Patent number: 8667632
    Abstract: A pneumatic seat cushion system (10) has a deformable cushion (11) having a seating surface (12) and a self inflating cushion bladder (14) positioned beneath the seating surface (12). The self inflating cushion bladder (14) has an airtight envelope (15) containing compressible material (16) which is in air communication (19) with a displacement bladder (18) such that when in use the airtight envelope (15) and the displacement bladder (18) form a closed system from which no air can enter or escape. When there is no person seated on the seating surface (12), the self inflating cushion bladder (14) is inflated and the displacement bladder (18) is deflated. When there is a person seated on the seating surface, the weight of the person compresses the compressible material (16) so as to partially deflate the self inflating cushion bladder (14) which results in the contained air passing into the displacement bladder (18) which becomes fully inflated.
