Patent ID: 8377018

Claim:
A reduced pressure treatment system for applying reduced pressure treatment to a tissue site, the system comprising: a canister comprising: a plurality of walls forming a liquid collection chamber, each wall having an inner surface and an outer surface; a first wall of the plurality of walls having a first recess formed in the outer surface of the first wall; a second wall of the plurality of walls having a second recess formed in the outer surface of the second wall; a first cover disposed over the first recess to form a first space; a second cover disposed over the second recess to form a second space; a first aperture disposed in the first wall to fluidly connect the first space and the liquid collection chamber; a second aperture disposed in the second wall to fluidly connect the second space and the liquid collection chamber; a first liquid-air separator positioned to substantially prevent liquid from the liquid collection chamber from entering the first space through the first aperture of the first wall; a second liquid-air separator positioned to substantially prevent liquid from the liquid collection chamber from entering the second space through the second aperture of the second wall; and a reduced pressure port fluidly connected to the first space and the second space; a reduced pressure source in fluid communication with the reduced pressure port to deliver a reduced pressure to the liquid collection chamber; and a manifold in fluid communication with the liquid collection chamber and adapted to be positioned at the tissue site to distribute the reduced pressure to the tissue site; wherein: the first recess is substantially L-shaped and includes a first leg portion intersecting a second leg portion at an apex region of the first recess; the first aperture is positioned in the apex region of the first recess; the second recess is substantially rectangular in shape and includes a first end and a second end; the second aperture is positioned at the first end of the second recess; the canister further comprises: a third aperture positioned in the first leg portion of the first recess opposite the apex region; a fourth aperture positioned in the second leg portion of the first recess opposite the apex region; a fifth aperture positioned at the second end of the second recess; a third liquid-air separator positioned to substantially prevent liquid from the liquid collection chamber from entering the first space through the third aperture; a fourth liquid-air separator positioned to substantially prevent liquid from the liquid collection chamber from entering the first space through the fourth aperture; and a fifth liquid-air separator positioned to substantially prevent liquid from the liquid collection chamber from entering the second space through the fifth aperture.
