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 tubings. 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 tubings 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.

An area support surface seating system designed to optimize conditions that will avoid interrupting the healing procedure of pressure injuries in the area of the buttocks while an individual is placed in the seated position through the control of individual cells within the support surface to create a lower than capillary pressure site under an open wound and modulate external pressure over time on different regions of the buttocks to minimize secondary causes of pressure injuries. The area support surface also provides through its operation the means to restrain the progress of spinal deformities.

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. The bathing apparatus may be used in combination with a support wall that includes a plurality of channels to hold household items.

Technologies are provided for determining a likelihood or risk of a human patient for developing pressure injury based on patterns of movement by the patient determined using a specialized measurement support surface. Some embodiments automatically ascertain whether patterns of movements of a human subject, whose weight is supported on the support surface, exhibit sufficient frequency and variability of activity such as will confer either certain health benefits or expose the individual to certain health risks, such as development of pressure ulcers in the load-bearing skin and soft tissues. The measurement support surface can include a contact layer, a pressure-measuring layer having an air bladder subjacent to the measurement support surface, and a substrate layer with a density and stiffness to mechanically isolate the pressure-measuring layer from ambient vibrations transmitted through a floor, furniture, or other intervening articles upon which the measurement support surface is mounted.

A wheelchair is provided. First supports for supporting a user of the wheelchair are unevenly disposed to form a perimeter, and second supports for supporting the user of the wheelchair are unevenly disposed at least partially within the perimeter of the first supports. The first supports support the user when the first supports are in a raised position and the second supports are in a lowered position. The second supports support the user when the second supports are in a raised position and the first supports are in a lowered position. A alternation of supporting the user with the first supports or the second supports facilitates reduction of pressure sores of the user. In various embodiments, multiple groups of supports are used, the supports contour to a user's anatomy and/or the supports are pneumatic.

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.

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.

An inflatable cushion comprising; a cover; a base; a communication device; a microcontroller; a power source; a gas pump; a primary tube; a blow off valve; two-way valves; a plurality of secondary tubes; and a plurality of bladder pods with pressure sensors.

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. The bathing apparatus may be used in combination with a support wall that includes a plurality of channels to hold household items.

Provided is an air-cushion block structure, and a mattress including the air-cushion block structure installed therein. The mattress of the present invention is provided with an air-cushion block structure which includes: an upper cushion having a first core hole vertically formed therein; and a lower cushion which has a second core hole vertically formed therein, and is disposed at a lower portion of the upper cushion. Accordingly, it is possible to stably transfer a weight of a user applied from an upper portion of the air-cushion block structure to a lower portion thereof, as well as, achieve a structure that stably supports the weight of the user by minimizing an occurrence of torsional deflection caused by the weight.
