Reduced-pressure, multi-orientation, liquid-collection canister

1. A liquid-collection canister for collecting liquid from a tissue site to which reduced pressure treatment is applied, the canister comprising:

a plurality of walls defining a liquid collection chamber configured to contact the liquid from the tissue site;

a first fluid pathway formed within a first wall of the plurality of walls;

a second fluid pathway formed within a second wall of the plurality of walls;

a first aperture disposed in the first wall and fluidly coupling the first fluid pathway and the liquid collection chamber; and

a second aperture disposed in the second wall and fluidly coupling the second fluid pathway and the liquid collection chamber.

2. The liquid-collection canister of claim 1 , further comprising:

a first liquid-air separator positioned over the first aperture to substantially prevent liquid passing through the first aperture; and

a second liquid-air separator positioned over the second aperture to substantially prevent liquid passing through the second aperture.

3. The liquid-collection canister of claim 2 , further comprising:

a third aperture disposed in the first wall to fluidly connect the first fluid pathway and the liquid collection chamber;

a fourth aperture disposed in the second wall to fluidly connect the second fluid pathway and the liquid collection chamber;

a third liquid-air separator positioned to substantially prevent liquid from the liquid collection chamber from entering the first fluid pathway through the third aperture of the first wall; and

a fourth liquid-air separator positioned to substantially prevent liquid from the liquid collection chamber from entering the second fluid pathway through the fourth aperture of the second wall.

4. The liquid-collection canister of claim 3 , wherein:

the first and third liquid-air separators are coplanar; and

the second and fourth liquid-air separators are coplanar.

5. The liquid-collection canister of claim 2 , wherein the first liquid-air separator and the second liquid-air separator are hydrophobic.

6. The liquid-collection canister of claim 2 , wherein the first liquid-air separator and the second liquid-air separator are oleophobic.

7. The liquid-collection canister of claim 1 , wherein:

the first aperture is one of a plurality of apertures covered by a first liquid-air separator; and

the second aperture is one of a plurality of apertures covered by a second liquid-air separator.

8. The liquid-collection canister of claim 1 , wherein the first wall is opposite the second wall.

9. The liquid-collection canister of claim 1 , wherein the first wall is adjacent the second wall.

10. The liquid-collection canister of claim 1 , wherein the canister further comprises:

a manifold chamber fluidly connected to the first fluid pathway and the second fluid pathway; and

a reduced pressure port fluidly connected to the manifold chamber.

11. The liquid-collection canister of claim 1 , further comprising an absorbent pad disposed within the liquid collection chamber.

12. The liquid-collection canister of claim 11 , wherein the absorbent pad comprises cellulose and sodium polyacrylate.

13. The liquid-collection canister of claim 12 , wherein the cellulose and sodium polyacrylate are contained within a non-woven polypropylene pouch.

14. The liquid-collection canister of claim 1 , wherein the first fluid pathway extends across substantially an entire width and length of the first wall.

15. The liquid-collection canister of claim 1 , wherein the second fluid pathway extends across substantially an entire width and length of the second wall.

16. The liquid-collection canister of claim 1 , wherein:

the first fluid pathway is integral with the first wall; and

the second fluid pathway is integral with the second wall.
