US 12,576,203 B2 · Fluid collection canister for use with sub-atmospheric pressure pump

Abstract

A fluid separation and collection canister operable in-line between a sub-atmospheric pump and a source of mixed fluid-gas flow. In one application, the present invention finds particular use in a healthcare environment to assist in the removal of fluids from a patient with internal or external injuries. The enclosed collection canister is made up of two case half shells separable at mid-line overlapping joint. The upper case half shell incorporates a suction port with a sub-micron gas filter, a pass-through port, and an upper fluid extraction port. The lower case half shell incorporates an inlet port with a one-way fluid valve, a lower pass-through port, and a lower fluid extraction port. The pass-through ports are used to carry a pressure monitoring lumen to the source of the mixed fluid-gas flow.
