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

摘要

A liquid-collection canister includes a liquid collection chamber defined by at least one wall and a first and second gas-communication pathway formed within the at least one wall. A first aperture is positioned between the first gas-communication pathway and the liquid collection chamber to allow gaseous communication between the liquid collection chamber and the first gas-communication pathway. A second aperture is positioned between the second gas-communication pathway and the liquid collection chamber to allow gaseous communication between the liquid collection chamber and the second gas-communication pathway. A first and a second liquid-air separator are positioned over the first aperture and the second aperture, respectively, to substantially prevent liquid passing through the first and second apertures.

主权项

1. A system for applying reduced-pressure treatment to a tissue site, the system comprising:
a liquid collection chamber formed by at least a first wall and a second wall, each wall having an inner surface and an outer surface; a first recess formed in the outer surface of the first wall; 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; 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; and a manifold in fluid communication with the liquid collection chamber and adapted to distribute reduced pressure to the tissue site.
