Abstract

A reduced pressure treatment system includes a porous pad positioned at a tissue site and a canister having a collection chamber, an inlet, and an outlet. The inlet is fluidly connected to the porous pad. A reduced pressure source is fluidly connected to the outlet of the canister to such that fluid from the tissue site may be drawn into the collection chamber. A hydrophobic filter is positioned adjacent the outlet to prevent liquid from exiting the collection chamber through the outlet. A baffle is positioned within the canister to create a tortuous path between the inlet and the outlet to prevent premature blocking of the hydrophobic filter.

Claims (9)

1. 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.

2. The system of claim 1 , wherein the baffle creates a tortuous path between the inlet and the outlet.

3. The system of claim 1 , wherein the baffle is a screen.

4. The system of claim 1 , wherein the liquid-air separator is a hydrophobic filter.

5. The system of claim 1 , wherein the baffle is positioned between a droplet-formation area and the outlet.

6. The system of claim 1 , wherein:

the baffle is positioned within the collection canister to receive droplets or spray from bubbles bursting within the collection canister;

the bubbles burst in a droplet-formation area of the collection canister; and

the baffle is positioned between the droplet-formation area and the outlet.
