Introduced here are pressure-mitigation systems able to mitigate the pressure applied to a human body by the surface of an object (also referred to as a “structure”). A controller device (or simply “controller”) can be fluidically coupled to a pressure-mitigation device that includes a series of selectively inflatable chambers. When a pressure-mitigation device is placed between a human body and a surface, the controller can continuously, intelligently, and autonomously circulate fluid through the chambers of the pressure-mitigation device. Normally, the controller circulates air through the chambers of the pressure-mitigation device, though the controller could circulate another fluid, such as water or gel, through the chambers of the pressure-mitigation device. The controller may cause the chambers to be selectively inflated, deflated, or any combination thereof.

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.

According to one embodiment, a seat cushion comprises a second air cell section that is located on the rear side of a seat surface and a third air cell section that is located rearward of the second air cell section. The second air cell section and the third air cell section are adjacent to each other and have a common boundary extending diagonally in the front-rear direction of the seat surface such that the ischial region of a user fits in the boundary.

An adjustable anatomical support and seat cushion apparatus for wheelchairs according to some embodiments of the disclosure includes a base member formed of at least one layer of a thermoplastic honeycomb material, a generally rectangular, resilient cushion member formed of upper, intermediate and lower layers of thermoplastic honeycomb material which are bonded together, and at least one pad removably insertable into a pocket in the lower layer. The base member is pivotally attached to the cushion member. The cushion member is rotatable between a non-parallel disposition and a parallel disposition relative to the base member. An open end of the pocket faces the base member when the cushion member is in the parallel disposition.

The invention is related to a wheelchair safety melody apparatus, which comprising: a wheelchair, including a seat pad; at least one handrail, fixed to the wheelchair; a pressure-sensitive seat pad, placed above the seat pad; and a safety melody generator, electrically connected with the pressure-sensitive seat pad, and being removably fixed at one side of the at least one handrail via a fastening element, wherein as a user leaves the seat of the wheelchair, the pressure-sensitive seat pad generates an initiating signal due to release of the pressure of the pressure-sensitive seat pad, thereby to allow the safety melody generator to generate an alarm signal for notifying a medical care person for assistance.

Introduced here are methods, apparatuses, and systems for mitigating the contact pressure applied to a human body by the surface of an object, such as a chair, bed, or table. A pressure-mitigation apparatus can include a series of chambers whose pressure can be individually varied. When placed between a patient and a contact surface, a controller can vary the contact pressure on the human body by controllably inflating one or more chambers, deflating one or more chambers, or any combination thereof. By monitoring the pressure in each chamber over time, the controller can also gain an enhanced understanding of movement(s) performed by the human body when positioned on the pressure-mitigation apparatus.

The present disclosure generally relates to a manifold valve assembly engaged to an inflatable apparatus, such as a cushion to prevent pressure ulcers, for example. The manifold valve assembly is also in communication with a processing device to determine an optimal immersion level for a user seated on the inflatable apparatus. Additionally the processing device, in communication with the manifold valve assembly may save optimal immersion or air pressure levels for comparison to future checks of cushion pressure and send that to a user interface at the processing device. The assembly and processing device may also save and dis play a history of pressure checks.

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.
