Abstract
Abstract Medical suction apparatus is disclosed including in combination a rigid outer canister having a cover and a disposable semi-rigid inner liner or container. Mounting assembly means coacts with the canister and cover to seal the container within the canister. The container is a cup-like member which maintains its cup-like shape before, during and after use within the canister. A simple and efficient snap-fit mounting assembly includes an annular sealing support lid on the upper peripheral lip of the container. The lid is snap-fit mounted to the rim of the canister to support the container therefrom. This mounting also establishes a gap between the container and canister, as well as sealing such gap. The cover is snap-fit mounted to the annular lid to compress the container lip and an upper section of the container sidewall between the cover and the lid. This mounting seals the interior of the container. The lid may be released from the canister without breaking the seal between the cover and container. There is further disclosed an overall system for saving hospital storage space.
