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.
Claims25
A system for treating a tissue site 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 to form a sealed treatment space;
- a reduced-pressure source for providing reduced pressure;
- and
- a container fluidly coupled to the reduced-pressure source and the sealed treatment space;
- wherein the container comprises:
- an interior space;
- a fluid inlet fluidly coupled to the sealed treatment space and the interior space;
- a reduced-pressure inlet fluidly coupled to the reduced-pressure source and the interior space;
- and
- a window having a hydrophilic polymer adapted to allow water vapor to egress from the interior space separately from the reduced-pressure inlet while retaining liquids and maintaining reduced pressure.
A container for receiving and processing body fluids, the container comprising:
- an interior space;
- a body fluid inlet fluidly coupled to the interior space;
- a reduced-pressure inlet fluidly coupled to the interior space;
- and
- a window having a hydrophilic polymer adapted to allow water vapor to egress from the interior space separately from the reduced-pressure inlet while retaining liquids and maintaining reduced pressure.
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:
- an interior space;
- a body fluid inlet fluidly coupled to the interior space;
- a reduced-pressure inlet fluidly coupled to the interior space;
- and
- a window having a hydrophilic polymer adapted to allow water vapor to egress from the interior separately from the reduced-pressure inlet while retaining liquids and maintaining reduced pressure;
- and
- evaporating and removing at least a portion of the water from the body fluids using the hydrophilic polymer.
