Portable wound therapy system

A system for storing fluid from a tissue site, the system comprising:

• a wound cover configured to surround a perimeter of a wound and the wound cover comprising a first wound facing side and a second side opposite the first side;
• a collection container adapted to be positioned on the second side of the wound cover and configured to be in fluid communication with the wound cover, wherein the collection container comprises a plurality of channels arranged in a general parallel, relation along a major portion of the respective lengths of the channels, wherein the collection canister comprises a first fluid channel of the plurality of channels and a second fluid channel of the plurality of channels and a channel separator between the first fluid channel and the second fluid channel, wherein the direction of fluid flow in the first channel of the plurality of channels is substantially opposite the direction of fluid flow in the second channel of the plurality of channels;
• wherein at least one of the first channel and the second channel are adapted to contain liquid from the tissue site.

A method of storing fluid from a tissue site, the method comprising:

• via a fluid flow path comprising a subatmospheric pressure source fluidically connected to a wound cover via a collection container, applying subatmospheric pressure to the wound cover to draw fluid away from the tissue site, wherein the collection container comprises a plurality of channels arranged in a general parallel relation along a major portion of the respective lengths of the channels, wherein the collection canister comprises a first fluid channel of the plurality of channels and a second fluid channel of the plurality of channels and a channel separator between the first fluid channel and the second fluid channel, wherein the direction of fluid flow in the first channel of the plurality of channels is substantially opposite the direction of fluid flow in the second channel of the plurality of channels, and wherein the wound cover comprises a first wound facing side and a second side opposite the first side and the collection container is positioned on the second side of the wound cover;
• and
• storing liquid from the tissue site in at least one of the first channel and the second channel.
