A pressure redistribution system, including: a chair having a frame; a back cushion inflation system operatively connected to an upper portion of the frame, wherein the back cushion inflation system includes a back cushion and a plurality of back cushion air bladders located within an opening in the back cushion; a pump system operatively connected to the back cushion inflation system for inflating and deflating the back cushion air bladders; a seat cushion sensor system operatively attached to the wheelchair frame and the pump system, wherein the seat cushion sensor system includes a seat cushion and a plurality of seat cushion air bladders located within an opening in the seat cushion and a plurality of load sensors located adjacent to the plurality of seat cushion air bladders and wherein the pump system is able to inflate and deflate the plurality of seat cushion air bladders; a light display operatively connected to the back cushion inflation system, wherein the light display provides a visual indication as to a pressure being experienced by each of the plurality of load sensors; and a microcontroller located adjacent to the pump system, the seat cushion sensor system and the light display to assist in a determination of the pressure being experienced by each of the plurality of load sensors and to assist in providing the visual indication as to a pressure being experienced by each of the plurality of load sensors.

A seating system for a chair in the form of a deflatable cushion. The two-inch-thick cushion, divided into nine rectangular sections, will have an open-end casing comprised of viscoelastic foam. The air compressor, connected to the battery power source, shoots pressurized gas into a check valve and then into branched rubber tubing's. The sequence of deflation is as follows: pressurized gas passes through the air compressor's plastic compartment, which encases antibacterial liquid that the gas can pass through before entering the check valve. Having exited the air compressor and entered the check valve, the valve will regulate the flow of air to the cushion based on synchronization with the compressor and electronic feedback from the application or manual control. Having entered the check valve, the pressurized, sanitary gas enters the rubber tubing's and the porous rubber tubes' eight subsections. This will cause deflation of the cushion. In addition, a heat sensor will be on the top-layer of the cushion and it can be linked to a computer for the user to monitor which areas of contact are too high in heat.

According to at least one embodiment, a pressure-eliminating seating apparatus for preventing formation and/or treating existing pressure ulcers, sores, or lesions, and/or relieving nerve pain in a lower region of an immobilized person, or any other user, is disclosed. The seating apparatus may include a body having a front edge, a pair of opposed side edges, a rear edge, a depth, and an aperture defined therein. To allow for the immobilized person, or other user, to sit comfortably and properly on top of the seating apparatus, the seating apparatus may be compressed to a depth of approximately 4 inches. The seating apparatus may also include a cover to prevent the depth from expanding to greater than approximately 4 inches. The apparatus may allow for suspension of bony prominences in the lower region of the immobilized person, or other user, in air.

The invention is directed to a device comprising a body that defines a first surface and a second surface and defines a first, second, third and fourth lateral sides. In one embodiment, the first surface defines a first aperture and a second aperture. In one embodiment, the thickness of the body along the first lateral side is greater than the thickness of the body along the third lateral side such that the first surface slopes downwards from the first lateral side towards the third lateral side. The device not only reduces the pressure on the tailbone or on the hemorrhoids for a person in a seated position, but also reduces the discomfort or pain associated with settling into a seated position or emerging from a seated position.

The invention provides a contouring system configured to be modified to provide a support surface, such as a backrest, seat base, or mattress, having contours to suit the needs of its user.

A cushion has at least one fluid chamber and at least one cushion conduit to enable fluid to be added to or removed from the at least one fluid chamber of the cushion. A management system for the cushion has a pressure sensor to measure a pressure of fluid in the at least one fluid chamber of the cushion and to transmit a sensor report with the measured pressure, a tube having a first end connecting to the cushion conduit, a second end leading to the pressure sensor, and a valve to enable fluid to be added to or removed from the at least one fluid chamber of the cushion through the cushion conduit and a processor to receive the sensor report, determine a pressure value of the at least one fluid chamber of the cushion based on the measured pressure in the sensor report, and generate a status indicative of the pressure value of the fluid chamber of the cushion.

A method for controlling a cushion is disclosed. The method involves receiving digital data that corresponds to signals from at least one pressure transducer that is pneumatically coupled to a bladder of a cushion, determining that the digital data includes an indication of at least one of a heart beat and breathing, determining that a person is sitting on the cushion in response to determining that the digital data includes an indication of at least one of a heart beat and breathing, and applying a control signal within the controller in response to determining that a person is sitting on the cushion.

Multi-layer cushion supports are described which may generally comprise a first support having a first contact surface for contacting a portion of a body and a second surface opposite to the first surface, the first support defining a central chamber and a peripheral chamber surrounding the central chamber, wherein the first support is filled with a first gas or liquid and a second support attached to the first support along the first contact surface. The second support may be filled with a second gas or liquid which is relatively more viscous than the first gas or liquid. In particular, the first support may be filled with a volume of air and the second support may be filled with oil which is less than the volume of air.

A dynamic support apparatus. The dynamic support apparatus includes a cushion, at least one actuator wherein the at least one actuator defines an interior volume and wherein the interior volume may be configured to be at least partially filled with a fluid, and a support disposed in the interior volume wherein the support configured to support an occupant when the interior volume is not filled with the fluid such that the support is sufficient to support the occupant.

A wheelchair seat cushion comprises a back pad module and a seat pad module which is connected with the back pad module. A resilient intermediate layer is provided within the back pad module and the seat pad module. A heat generating device is provided within in the resilient intermediate layer, wherein the heat generating device is positioned corresponding to at least one acupuncture point of a back of a user, and heat generated by the heat generating device is conducted to a body of the user via the at least one acupuncture point in order to keep the body of the user warm.
