Patent ID: 8172818

Claim:
A reduced pressure treatment system for applying reduced pressure treatment to a tissue site, the system comprising: a liquid-collection canister comprising: a first space configured to collect the liquid from the tissue site; a second space configured to receive a reduced pressure; a plurality of liquid-air separators positioned within the canister between the first space and the second space such that the liquid in the first space is substantially prevented from entering the second space, the plurality of liquid-air separators allowing transfer of a gas between the second space and the first space, at least two of the plurality of liquid-air separators being substantially planar and each of the two located within different planes, wherein a first plane associated with a first of the two liquid-air separators is parallel to a second plane associated with a second of the two liquid-air separators; a canister inlet associated with the first space; and a canister outlet associated with the second space; a reduced pressure source in fluid communication with the canister outlet to deliver a reduced pressure to the second space; and a manifold positioned at the tissue site and in fluid communication with the canister inlet to distribute the reduced pressure to the tissue site.
