System and method for collecting exudates

A collection canister for use with a reduced pressure treatment system, the 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;
• and
• a baffle positioned within the canister to deflect liquid entering the canister from prematurely blocking the liquid-air separator;
• wherein the baffle includes a deflector plate;
• wherein at least one raised member is positioned on the deflector plate to burst bubbles that form as fluid enters the collection chamber.

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

• a 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;
• an inlet disposed in the entry wall of the entry chamber, the inlet adapted to be fluidly connected to a tissue site;
• an outlet in communication with the collection chamber and adapted to be fluidly connected to a reduced pressure source;
• a hydrophobic filter positioned adjacent the outlet to prevent liquid from exiting the collection chamber through the outlet;
• and
• a baffle having a base and a deflector plate, the base being removably positioned within the entry chamber through the opening of the entry chamber;
• wherein the deflector plate of the baffle deflects liquid entering the entry chamber through the inlet from prematurely blocking the hydrophobic filter;
• wherein at least one raised member is positioned on the deflector plate to burst bubbles that form as fluid enters the collection chamber.

A collection canister for use with a reduced pressure treatment system, the 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;
• and
• a baffle positioned within the canister to receive droplets or spray from bubbles bursting within the canister;
• wherein the baffle includes a deflector plate;
• wherein at least one raised member is positioned on the deflector plate to burst bubbles that form as fluid enters the collection chamber.

A method for collecting exudate from a tissue site comprising:

• creating a reduced pressure within a collection canister to draw exudate from the tissue site to the collection canister, the collection canister having an outlet and a liquid-air separator associated with the outlet;
• and
• minimizing deposition of protein from the exudate on the liquid-air separator;
• wherein said minimizing said deposition of protein further comprises:
• providing a baffle within the collection canister to deflect exudate entering the canister;
• wherein the baffle includes a deflector plate;
• wherein at least one raised member is positioned on the deflector plate to burst bubbles that form as exudate enters the collection chamber.
