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 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 support system for the human body, or a human body segment, is provided. The system comprises a covering lining in which a plurality of pockets is defined in which there are inserted one or more filling elements forming together a cushioning arrangement of the support system. Filling elements with different physical properties, for example different stiffnesses, are inserted in the different pockets of the covering lining. The pockets may be independent of one another and removably connected to one another, so that they can be combined with one another in the way that best adapts to the specific morphology of a single user. The support system can be made, for example, in the form a cushion, a seat, a backrest, a mattress or with any other shape that may be desired.

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.

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 seat cushion assembly includes a base defining a leg support, a support portion recessed relative to the leg support, and a well recessed relative to the support portion, and an air pad assembly including a first air support member and a second air support member, the first air support member being positioned on the recessed support portion, and the second air support member being removably received by the well.

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.

A seat system for a wheelchair. The seat system comprises: a left-thigh support comprising an upper-thigh support part and a lower-thigh support part; and a right-thigh support comprising an upper-thigh support part and a lower-thigh support part; wherein the lower-thigh support part of the left-thigh support is separate to the lower-thigh support part of the right-thigh support, and either the upper-thigh support part or the lower-thigh support part of each of the left- and right-thigh supports comprises one or more first engagement members and the other of the upper-thigh support part or the lower-thigh support part of each of the left- and right-thigh supports comprises two or more second engagement members, each of the first engagement members being received or receivable between two of the two or more second engagement members such that the one or more first engagement members and the two or more second engagement members are configured to cooperate with one another in a slidable relationship, such that a length of each of the left- and right-thigh supports is adjustable.
