Systems and methods for reduced pressure tissue treatments, including a multi-orientation canister. The canister includes an inlet for receiving fluids from a tissue site, and a main chamber in fluid communication with the inlet for receiving fluids from the inlet. The canister includes a filter chamber separated from the main chamber by one or more filter chamber walls. The one or more filter chamber walls includes a primary hole having a first diameter and a secondary hole having a second diameter smaller than the first diameter. The primary hole provides a first path of fluid communication between the filter chamber and the main chamber. The canister includes an outlet for providing fluid communication between the filter chamber and a reduced pressure source.

1. A canister for use in a reduced pressure tissue treatment, the canister comprising: a main chamber having an inlet adapted to receive liquid from a tissue site;a filter chamber isolated from the main chamber by one or more walls, the filter chamber having an outlet adapted to be fluidly coupled to a reduced pressure source;a first aperture and a second aperture extending through the one or more walls, wherein the first aperture is configured to provide fluid communication between the main chamber and the filter chamber when the liquid in the main chamber reaches the first aperture and the second aperture, and wherein the second aperture is vertical to a force of gravity when the canister is in a primary operating orientation; anda filter positioned within the filter chamber. 2. The canister of claim 1, further comprising a liquid-air separator positioned adjacent the outlet. 3. The canister of claim 1, the filter being isolated from the main chamber by the one or more walls. 4. The canister of claim 1, further comprising a baffle positioned adjacent the inlet to inhibit splashing of fluids as the fluids enter the canister through the inlet. 5. The canister of claim 1, further comprising a gelling agent positioned within the main chamber for creating a gel upon contact with fluids received from the tissue site. 6. The canister of claim 1, wherein the first aperture is positioned beneath the second aperture in the canister's primary operating orientation. 7. The canister of claim 1, wherein the first aperture is horizontal to a force of gravity when the canister is in the primary operating orientation. 8. The canister of claim 1, wherein: the first aperture is positioned beneath the second aperture in the canister's primary operating orientation; andthe first aperture is horizontal to a force of gravity when the canister is in the primary operating orientation. 9. The canister of claim 1, wherein the second aperture is smaller than the first aperture. 10. The canister of claim 1, wherein the first and the second aperture are configured to provide fluid communication between the main chamber and the filter chamber when the liquid in the main chamber reaches the second aperture. 11. The canister of claim 1, wherein the first aperture is configured to provide less restrictive fluid communication between the main chamber and the filter chamber than fluid communication through the second aperture when the liquid in the main chamber reaches the first aperture and the second aperture. 12. A liquid-collection canister comprising: a first chamber and a second chamber fluidly isolated by one or more walls; anda plurality of apertures positioned in the one or more walls to provide fluid communication between the first chamber and the second chamber, wherein one of the plurality of apertures is located at a centroid of the liquid-collection canister. 13. The liquid-collection canister of claim 12, wherein the first chamber is a main chamber and the second chamber is a filter chamber, the liquid-collection canister further comprising: an inlet capable of receiving fluids from a tissue site, the inlet adapted to provide fluid communication between the tissue site and the main chamber;one aperture of the plurality of apertures positioned in a plane perpendicular to another of the plurality of apertures, the one aperture having a first diameter and the another aperture having a second diameter smaller than the first diameter; andan outlet providing fluid communication with the filter chamber, the outlet adapted to be fluidly connected to a reduced pressure source. 14. The liquid-collection canister of claim 13, further comprising a liquid-air separator positioned adjacent the outlet. 15. The liquid-collection canister of claim 13, further comprising a filter positioned within the filter chamber and isolated from the main chamber by the one or more walls. 16. The liquid-collection canister of claim 13, further comprising a baffle positioned adjacent the inlet to inhibit splashing of fluids as the fluids enter the liquid-collection canister through the inlet. 17. The liquid-collection canister of claim 13, further comprising a gelling agent positioned within the main chamber for creating a gel upon contact with fluids received from the tissue site. 18. The liquid-collection canister of claim 13, wherein the liquid-collection canister has a primary operating orientation. 19. The liquid-collection canister of claim 18, wherein the one aperture is positioned beneath the another aperture in the liquid-collection canister's primary operating orientation. 20. The liquid-collection canister of claim 18, wherein the one aperture is horizontal to a force of gravity when the liquid-collection canister is in the primary operating orientation. 21. The liquid-collection canister of claim 18, wherein the another aperture is vertical to a force of gravity when the liquid-collection canister is in the primary operating orientation. 22. A reduced pressure delivery system for applying a reduced pressure tissue treatment to a tissue site comprising: a liquid-collection canister comprising: a first chamber and a second chamber fluidly isolated by one or more walls, anda plurality of apertures positioned in the one or more walls to provide fluid communication between the first chamber and the second chamber,wherein at least one of the apertures is vertical relative to a force of gravity in a primary operating position of the liquid-collection canister;a reduced pressure source for applying reduced pressure the tissue site;a manifold positioned adjacent the tissue site; anda conduit fluidly connected between the first chamber and the manifold for delivering fluids from the tissue site to the first chamber. 23. A reduced pressure delivery system for applying a reduced pressure tissue treatment to a tissue site comprising: a liquid-collection canister comprising: a first chamber and a second chamber fluidly isolated by one or more walls, anda plurality of apertures positioned in the one or more walls to provide fluid communication between the first chamber and the second chamber, andwherein at least one of the apertures is vertical relative to a force of gravity in a primary operating position of the liquid-collection canister. 24. A canister for use in a reduced pressure tissue treatment, the canister comprising: a main chamber having an inlet adapted to receive liquid from a tissue site;a filter chamber isolated from the main chamber by one or more walls, the filter chamber having an outlet adapted to be fluidly coupled to a reduced pressure source; anda first aperture and a second aperture extending through the one or more walls, wherein the first aperture is configured to provide fluid communication between the main chamber and the filter chamber when the liquid in the main chamber reaches the first aperture and the second aperture, and wherein the second aperture is smaller than the first aperture. 25.
