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.
Claims44
A system for treating a tissue site on a patient with reduced pressure, the system comprising:
- a treatment manifold for placing proximate to the tissue site;
- a sealing member for forming a fluid seal over the treatment manifold and a portion of the patient's epidermis whereby a sealed treatment space is formed;
- a reduced-pressure source for providing reduced pressure;
- a container for receiving fluids, wherein the container is fluidly coupled to the reduced-pressure source and the sealed treatment space;
- wherein the container comprises:
- a container housing defining an interior space for receiving the fluids;
- a fluid inlet through the container housing, the fluid inlet for receiving the fluids into the interior space of the container housing;
- and
- wherein at least a portion of the container housing comprises a liquid-impermeable, vapor-permeable material that allows egress of evaporated water from the fluids.

A container for receiving and processing body fluids, the container comprising:
- a container housing having an interior space for receiving the body fluids;
- a body fluid inlet through the container housing, the body fluid inlet for receiving body fluids into the interior space of the container housing;
- and
- wherein at least a portion of the container housing comprises a material that is substantially liquid impermeable and vapor permeable.

A method for processing body fluids from a patient, the method comprising:
- causing the body fluids to enter into a container, wherein the container comprises:
- a container housing having an interior space for receiving the body fluids,
- a body fluid inlet through the container housing, the body fluid inlet for receiving body fluids into the interior space of the container housing, and
- wherein at least a portion of the container housing comprises a liquid-impermeable, vapor-permeable material;
- and
- evaporating and removing at least a portion of the water from the body fluids using the liquid-impermeable, vapor-permeable material.
