Abstract
Body-fluid containers, methods, and systems are presented that include a container that has a container housing formed, at least in part, by a liquid-impermeable, vapor-permeable material. The liquid-impermeable, vapor-permeable material allows water to evaporate and be transmitted outside of the container. The evaporation allows more fluid to be processed by the container than the container could otherwise hold. Other systems, methods, and apparatuses are presented.
Claims20
A system for treating a tissue site with reduced pressure, the system comprising:
- a manifold configured to be placed proximate to the tissue site;
- a sealing member configured to cover the manifold and the tissue site to form a sealed space;
- a reduced-pressure source configured to be fluidly coupled to the sealed space;
- and
- a container for receiving body fluids from the tissue site, the container comprising:
- at least one wall having a plurality of apertures,
- a liquid-impermeable, vapor-permeable material defining a portion of an interior space of the container, wherein the liquid-impermeable, vapor-permeable material is coupled to the at least one wall and covers the plurality of apertures,
- a fluid inlet fluidly coupled to the interior space and configured to be fluidly coupled to the sealed space,
- a fluid outlet fluidly coupled to the interior space and configured to be fluidly coupled to the reduced-pressure source, wherein the fluid outlet is separate from the plurality of apertures, and
- a filter disposed in the fluid outlet;
- wherein the liquid-impermeable, vapor-permeable material is adapted to come into contact with the body fluids received in the container and is adapted to retain the body fluids received in the container.
A container for storing fluids from a tissue site treated with reduced pressure, the container comprising:
- at least one wall having an opening;
- a liquid-impermeable, vapor-permeable material defining a portion of an interior space of the container, wherein the liquid-impermeable, vapor-permeable material is coupled to the at least one wall and covers the opening;
- a fluid inlet fluidly coupled to the interior space;
- a fluid outlet fluidly coupled to the interior space, wherein the fluid outlet is separate from the opening;
- and
- a filter disposed in the fluid outlet;
- wherein the liquid-impermeable, vapor-permeable material is adapted to contact and retain fluids received in the interior space.
A container for storing fluids from a tissue site treated with reduced pressure, the container comprising:
- at least one wall defining a plurality of apertures;
- a liquid-impermeable, vapor-permeable material forming a portion of the wall and covering the plurality of apertures;
- a fluid inlet configured to be fluidly coupled to a sealed space;
- and
- a fluid outlet configured to be fluidly coupled to a reduced-pressure source, wherein the fluid outlet is separate from the plurality of apertures;
- wherein the liquid-impermeable, vapor-permeable material is adapted to contact and retain fluids received in the container.

- a liquid-impermeable, vapor-permeable material defining a portion of an interior space of the container configured to receive body fluids, the liquid-impermeable, vapor-permeable material coupled to the at least one wall, covering the opening, and having a portion configured to cross a fluid level surface of the body fluids,
- a fluid inlet fluidly coupled to the interior space and configured to be fluidly coupled to the sealed space,
- a fluid outlet fluidly coupled to the interior space and configured to be fluidly coupled to the reduced-pressure source, wherein the fluid outlet is separate from the opening, and
- a filter disposed in the fluid outlet.
