Evaporative fluid pouch and systems for use with body fluids
First Claim
Patent Images
1. A system for treating a tissue site on a patient with reduced-pressure, the system comprising:
- a reduced-pressure dressing for disposing proximate to the tissue site;
a first reduced-pressure conduit fluidly coupled to the reduced-pressure dressing for delivery of reduced pressure thereto; and
an inline storage-and-liquid-processing pouch having a first chamber and a second chamber, wherein the first chamber is fluidly coupled to the first reduced-pressure conduit and configured to be fluidly coupled to a reduced-pressure source, and wherein the second chamber has an evaporation port adapted to allow air to flow out of the second chamber and is configured to be fluidly coupled to a positive-pressure source.

Abstract
An inline storage-and-liquid-processing pouch for use with body fluids from a patient is presented that involves introducing body fluids into a first chamber in the storage-and-liquid-processing pouch and flowing air through a second chamber. The chambers are separated by a high-moisture-vapor-transfer-rate member. The air flow in the second chamber enhances liquid removal from the first chamber across the high-moisture-vapor-transfer-rate member. Other systems, devices, and methods are disclosed herein.
