Vacuum port connector assembly on fluid collection apparatus

Claim 1

A suction apparatus for suctioning and collecting fluid from a patient comprising: a rigid outer canister having an annular rim defining an upwardly opening mouth; a disposable semi-rigid inner container having an annular lip extending laterally from said container sidewall and overlying a portion of said canister rim, said container removably disposed within said canister and supported from the top of said canister with a space between the sidewalls of said canister and said container; a removable cover for said canister and container having formed therein an inlet port for receiving fluid from the body of a patient, and a vacuum port for effecting a vacuum within said container for drawing fluid through said inlet port for collection in said container; an inlet line; a vacuum line; a tee connection attached directly to the rigid outer canister and communicating with the interior of the rigid outer canister to allow easy disconnection and reconnection of the vacuum line to the vacuum source; a flexible autoclavable vacuum leader line having first and second ends and having a length for extending between said tee connection and said vacuum port, said tee connection and said vacuum port, said first end being permanently attached to said tee connection and said second end having detachable vacuum coupling means for attaching said second end to the vacuum port, such that a vacuum applied to said tee from the vacuum line is applied to the exterior and interior of the inner liner; said vacuum coupling means including a male-type connector attached to said second end of said vacuum leader line and said vacuum port including a female-type connector, said male connector being dimensioned to interfit with said female-type connector and being inoperable to couple said vacuum leader line to said inlet port; and inlet coupling means for attaching the inlet line to the inlet port, said inlet coupling means being inoperable to couple the inlet line to the vacuum port, said inlet coupling means being readily distinguishable from said vacuum coupling means such that attempts to miscouple are minimized.
