EVAPORATIVE FLUID POUCH AND SYSTEMS FOR USE WITH BODY FLUIDS
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.
1 . An inline pouch for delivering reduced-pressure to a reduced-pressure dressing, comprising:
a pouch body;
a dividing member disposed within the pouch body, the dividing member partitioning the pouch body into a first chamber and a second chamber;
a wicking member disposed within the first chamber;
a manifold member disposed within the second chamber;
a first port disposed on the pouch body, the first port being in fluid communication with the first chamber, the first port adapted to fluidly couple the first chamber to a reduced-pressure source; and
a second port disposed on the pouch body, the second port being in fluid communication with the second chamber.
2 . The inline pouch of claim 1 , wherein the dividing member is adapted to permit vapor transfer between the first chamber and the second chamber.
3 . The inline pouch of claim 1 , wherein the second port is configured to allow air to enter the second chamber from an external environment.
4 . The inline pouch of claim 1 , wherein:
the second port is located at an end of the pouch body; and
the second port is configured to allow air to enter the second chamber from an external environment and flow along a length of the second chamber.
5 . The inline pouch of claim 1 , further comprising a third port in fluid communication with the second chamber.
6 . The inline pouch of claim 5 , wherein:
the second port is located at an end of the pouch body; and
the second port is configured to allow air to enter the second chamber from an external environment and flow along a length of the second chamber to exit the second chamber through the third port.
7 . The inline pouch of claim 5 , further comprising a fourth port in fluid communication with the first chamber.
8 . The inline pouch of claim 7 , wherein:
the first port is disposed at an end of the pouch body;
the first port is configured to allow reduced-pressure to enter the first chamber from the reduced-pressure source; and
the fourth port is configured to allow reduced-pressure to be communicated from the first chamber to the dressing.
9 . The inline pouch of claim 1 , wherein the pouch body comprises is formed with exterior walls having an interior portion.
10 . The inline pouch of claim 9 , wherein the dividing member divides the interior portion into the first chamber and the second chamber.
11 . The inline pouch of claim 9 , wherein the exterior walls are formed by a first sealing member and a second sealing member.
12 . The inline pouch of claim 11 , wherein the first sealing member is bonded to the second sealing member at a periphery of the first sealing member and the second sealing member.
13 . The inline pouch of claim 12 , wherein the dividing member is disposed between the first sealing member and the second sealing member.
14 . The inline pouch of claim 1 , wherein the wicking member comprises a non-woven fabric.
15 . The inline pouch of claim 1 , wherein the wicking member comprises a 3D spacer fabric.
16 . The inline pouch of claim 1 , wherein the wicking member comprises a textile.
17 . The inline pouch of claim 1 , wherein the wicking member comprises an open-cell foam.
18 . The inline pouch of claim 1 , wherein the wicking member comprises a fabric layer.
19 . The inline pouch of claim 1 , wherein the wicking member is configured to allow fluid to flow in the first chamber.
20 . The inline pouch of claim 1 , wherein the manifold member is configured to allow air to flow in the second chamber.
