Patent ID: 8905986

Claim:
A reduced pressure treatment system comprising: a manifold positioned at a tissue site; a collection canister having a collection chamber, an inlet, and an outlet, the inlet being fluidly connected to the manifold and the outlet being positioned on an exit wall of the collection chamber; a reduced pressure source fluidly connected to the outlet of the collection canister to deliver a reduced pressure to the collection chamber and the tissue site such that fluid from the tissue site is drawn into the collection chamber; a liquid-air separator associated with the outlet to prevent liquid from exiting the collection chamber through the outlet; a baffle positioned within the collection canister to deflect liquid entering the collection canister from prematurely blocking the liquid-air separator, the baffle including a deflector plate that is angled, when positioned within the collection canister, relative to a level-liquid line of the collection canister to direct fluid contacting the deflector plate away from the exit wall; wherein the baffle includes at least one raised member positioned on the deflector plate to burst bubbles that form as fluid enters the collection chamber.
