Abstract: Apparatus for an electrically powered fluid feature comprises a unit including a fluid pump and a rechargeable power source arranged to provide power to the pump for operation of the fluid feature. The power source may be rechargeable via electrical contacts. The unit may comprise upper and lower housing portions that are separable to allow cleaning, replacement or recycling of components. The unit may be removably installed in a reservoir, which is supported within a container by adjustable supports.

Abstract: A mattress apparatus including a foam layer, an inflatable air cushion superposed with the foam layer, a first pneumatic line in fluid communication with the air cushion, and a non-shearing layer covering at least a portion of the air cushion. The air cushion can be inflated to support a patient such that the air cushion contours the patient's body and disperse pressure portions over a larger area, thereby helping eliminate pressure points which can cause or worsen skin wounds. The non-shearing layer can help prevent further tearing or pulling of the skin as a patient moves on the mattress. The foam layer can comprise viscoelastic polyurethane. The apparatus can include a removable cover at least partially surrounding the foam layer, inflatable air cushion, pneumatic first line, and non-shearing layer. An air passage can be defined through the removable cover.
