Abstract

A support structure, such as a mattress, is provided for the placement and removal of a human waste container, such as a bedpan, with minimal exertion by the attendant and minimal movement of the person. The mattress is provided with a cavity equipped with a controllable expandable cushion. Prior to use, the bedpan is placed in the cavity on top of the contracted cushion and the cushion is expanded to raise the bedpan directly under the person. A mattress protector extends into the cavity to protect the cavity from leaks or spills which may result during the person'"'"'s use of the bedpan. When fully expanded, the cushion completely fills the cavity so that it is substantially flush with the rest of the mattress. A bedsheet covers the mattress and is provided with a fly or flap for access to the cavity. A disposable wastebag system can be arranged onto the cavity for use in place of a bedpan. For added hygiene of the person using the bedpan or wastebag, the mattress can be arranged with a bidet system that releases a fluidic cleaning agent from a storage container into tubing embedded in the mattress, the fluid being finally expelled onto the part of the person'"'"'s lower body exposed within the cavity.
