Abstract
A moisture trap for removing liquid from a fluid drawn from a tissue site treated with reduced pressure and systems and methods for using the same are described. The moisture trap may include a barrier adapted to be fluidly coupled to and define an indirect fluid path between a fluid reservoir and a reduced-pressure source. The barrier may have a hydrophilic surface. The moisture trap also may include a sump adapted to receive condensation from the barrier.
Claims28
A system for treating a tissue site with reduced pressure, the system comprising:
- a dressing adapted to be placed adjacent to the tissue site;
- a reduced-pressure source adapted to be fluidly coupled to the tissue site;
- a canister having three pairs of opposing walls forming a fluid reservoir adapted to be fluidly coupled to the dressing and adapted to be fluidly coupled to the reduced-pressure source through at least one wall of one of the three pairs of opposing walls;
- and
- a trap disposed in the canister adjacent the at least one wall of one of the three pairs of opposing walls and fluidly separating a portion of the fluid reservoir, the trap comprising a barrier and a sump adapted to receive condensation from the barrier, the barrier having a hydrophilic surface and defining an indirect fluid path between the fluid reservoir and the reduced-pressure source.
A canister for collecting fluids, the canister comprising:
- a fluid reservoir formed by at least a top wall and a bottom wall;
- a fluid outlet formed in the top wall and adapted to be fluidly coupled to a reduced-pressure source;
- and
- a trap disposed in the fluid reservoir adjacent the fluid outlet and fluidly separating a portion of the fluid reservoir, the trap comprising a barrier and a sump adapted to receive condensation from the barrier, the barrier having a hydrophilic surface and defining an indirect fluid path between the fluid reservoir and the reduced-pressure source.
A method of manufacturing a canister for a reduced-pressure therapy system, the method comprising:
- providing three pairs of opposing walls forming a fluid reservoir;
- providing a fluid inlet through at least one wall of one of the three pairs of opposing walls, the fluid inlet configured to be fluidly coupled to a reduced-pressure inlet of a fluid reservoir;
- providing a fluid outlet in at least one wall of one of the three pairs of opposing walls, the fluid outlet configured to be fluidly coupled to a reduced-pressure source;
- forming a barrier having a hydrophilic surface;
- positioning the barrier within a separately enclosed space in the fluid reservoir, between the fluid inlet and the fluid outlet to define an indirect fluid path between the fluid reservoir and the reduced-pressure source;
- and
- positioning a sump to receive liquid condensed by the barrier.
