An encapsulated zonal dual air and foam spring bed system with noise suppression wherein air zones are created for individual or multiple sleepers that permit costs saving by providing manifold controls to enable a single pump to serve multiple circuits simultaneously (both pressure level increase and pressure level decrease) that is contained within a complete noise deadening structure whose body is easily formed to reduce cost and provide sanitation. Through the reduction of stress by cycling air support between two areas that in unison and each at half pressure support subject fully.

The apparatuses and methods of making and using the same are directed to bathing apparatus to support an object while bathing the object with a fluid. The bathing apparatus may comprise a support assembly constituting a support structure of the apparatus; a support surface to support the object, the support surface supported by the support portion; and a fluid catch disposed on at least three sides of the support surface, the fluid catch serving as a basin for the fluid in such manner to contain the fluid separate from the support surface.

A multi-position airflow control assembly includes a valve body fluidly connected to at least three inflation zones of a cushion, a control assembly partially received by the valve body, the control assembly including a seal member, and an actuation assembly operably connected to the seal member and configured to rotate the seal member relative to the valve body between at least a first position and a second position. In the first position, the seal member is configured to fluidly isolate the at least three inflation zones from each other. In the second position, the seal member is configured to group the at least three inflation zones into a first group of inflation zones being fluidly connected, and a second group of inflation zones being fluidly connected, the first group of inflation zones being fluidly isolated from the second group of inflation zones.

Therapeutic cushions having a plurality of inflatable columnar cells, pumping mechanism, and a manifold or valve system for moving a fluid between the pumping mechanism and the inflatable columnar cells. The inflatable columnar cells are constructed such that inflation and deflation of the cells cause vertical expansion/contraction of the cells with limited lateral expansion/contraction. The manifold or the valve system connect the pumping mechanism with the inflatable columnar cells such that a plurality of zones are created. A valve assembly can include a plurality of valves and is adjustable among at least three valve configurations to vary fluid connections to the inflatable columnar cells to produce rearwardly advancing waves. A venting manifold may vent air from the cells between the cushions.

It is common for people who have postural problems to use wheelchairs. It is a problem that extended periods spent in the wheelchair can cause pressure on a particular body part. The invention discloses a seat comprising a cushion. The cushion comprises a flexible bag containing a plurality of pads and a liquid. The cushion is such that the liquid facilitates movement of the pads with respect to one another to mould the cushion in the event that a human user places body weight on the cushion.

A wheelchair cushion comprises a dual stiffness fluid. A cushion also comprises an ability to adjust fluid volume.

A double-shell helmet is disclosed. The double-shell helmet includes an outer shell, an impact absorbing material layer affixed to the outer shell on a first side of the impact absorbing material layer, an inner shell affixed to the impact absorbing material layer on a second side of the impact absorbing material layer opposite the first side of the impact absorbing material layer, and a foam layer affixed to the inner shell.

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.

A medical rehabilitation chair includes a main frame, multiple castor devices mounted on the bottom of the main frame, and two armrest boards mounted on two sides of the main frame. A telescopic damping driver, a seat frame assembly, a backrest frame assembly, a leg support assembly, a lifting mechanism, and a foot support assembly are assembled on the main frame. The seat frame assembly has a front section connecting the leg support assembly and a rear section connecting the backrest frame assembly. The telescopic damping driver drives the backrest frame assembly, the seat frame assembly, and the leg support assembly, to produce different swinging angles. The lifting mechanism drives the seat frame assembly to lift or lower. The foot support assembly is movable in a horizontal direction to protrude from the front section of the main frame.

A cushioning device for supporting a user in seated or recumbent posture, e.g., in a wheelchair, comprises a resiliently compressible foam base layer with an upper surface formed of a configuration generally conforming to the user's body and defining a fluid drainage path to a fluid drainage and collection area in case of incontinence episodes, an absorbent layer disposed in association with the fluid collection area for collection and holding fluids draining to the collection area, a fluid-impermeable bottom layer covering the underside of the base layer, and a non-absorbent top layer covering the upper surface of the base layer. Together, the fluid permeability and non-absorbent character of the top layer and the compressible resiliency and drainage configuration of the foam base layer for draining fluids to the absorbent layer, mitigate pressure, heat, moisture, shear and friction conditions that are the main contributing causes to formation of decubitus ulcers.
