System and method for collecting exudates

A collection canister for use with a reduced pressure treatment system, the collection canister comprising:

• a collection chamber;
• an inlet adapted to be fluidly connected to a tissue site;
• an outlet adapted to be fluidly connected to a reduced pressure source;
• a liquid-air separator positioned adjacent the outlet;
• a baffle positioned within the collection canister to deflect liquid entering the collection canister from prematurely blocking the liquid-air separator, wherein the baffle comprises a shroud and a deflector plate;
• at least one raised member positioned on the deflector plate to burst bubbles that form as fluid enters the collection chamber;
• an entry chamber positioned above the collection chamber, the entry chamber having an open end and a closed end defined by an entry wall, the entry chamber further having a floor separating the entry chamber from the collection chamber, the floor having an aperture allowing communication between the entry chamber and the collection chamber;
• and
• a porous foam positioned in the entry chamber to minimize bubble formation near the open end of the entry chamber,
• wherein the inlet is disposed in the entry wall of the entry chamber.
