## Abstract

A collection, storage and disposal system for human wastes. An externally positionable patient interface directs wastes through a conduit to a storage container. Accumulated wastes are sealed within the storage container to prevent cross-contamination. The patient interface is extendable through an aperture formed within a seat portion of a support structure which can be converted between bed and chair configurations. A mattress has a foam insert which may be selectively inflated to maintain desired supporting pressure for the patient and to provide a resilient support surface should deflation of the mattress occur.

## Claims

### Claim 1

A replacement waste collection unit, comprising:
an outer canister including a closed bottom wall and at least one closed side wall having an upper edge, and a removable top wall having an aperture and a sealing lid removably closing said aperture;
an upstanding supporting liner disposed within said canister, said liner defining a central well;
a reservoir bag within said canister and straddling said supporting liner;
a waste receptacle bag within said canister and straddling said supporting liner; and
a patient interface, adapted for external engagement with an area at least partially surrounding a human anal region and adapted to be operatively connected to said receptacle bag, within the canister.
