Canister for wound therapy and related methods therefor

摘要

A portable system for subatmospheric pressure therapy in connection with healing a surgical wound includes a wound dressing dimensioned for positioning relative to a wound bed and a collection canister in fluid communication with the wound dressing. The canister includes a first vacuum chamber for drawing a vacuum and a second fluid chamber for collecting fluids removed from the wound dressing under the vacuum. The canister further includes a hydrophobic membrane separating the first and second chambers. The hydrophobic membrane is dimensioned to span a major portion of the cross-sectional area of the canister. The hydrophobic membrane may be dimensioned to substantially span an internal dimension of the collection canister. The hydrophobic membrane may include one or more outwardly extending lobes. The hydrophobic membrane may be releasably mountable to the canister, and, may be supported within a divider separating the first vacuum chamber and the second fluid chamber.

主权项

1. A collection canister comprising:
a first chamber fluidly connectable to a vacuum source for drawing a vacuum; a second chamber including a cavity for receiving fluid drawn under the vacuum; a hydrophobic membrane separating the first chamber and the second chamber, the hydrophobic membrane dimensioned to span at least a portion of the cross-sectional area of the collection canister and including one or more lobes extending outwardly relative to a central longitudinal axis extending along a length of the collection canister, the one or more lobes positioned and dimensioned for permitting vacuum draw upon tilting, inverting, or placing the collection canister on a side thereof; and a divider supporting the hydrophobic membrane between the first chamber and the second chamber, wherein the divider includes one of a screen, grill, or a mesh.
