## Abstract

A system and apparatus for treating a tissue site with reduced pressure and collecting fluids from the tissue site is disclosed. The system may include a reduced-pressure source, a pouch in fluid communication with the reduced pressure source, and a dressing in fluid communication with the pouch. The pouch may include a first wall, a second wall having a periphery coupled to the first wall to form an interior, and a third wall extending through the interior to form a first chamber in fluid communication with the dressing and a second chamber in fluid communication with the reduced pressure source. A plurality of filters are positioned in the third wall. The filters permit fluid communication between the first chamber and the second chamber.

## Claims

forming a pouch with a first chamber and a second chamber;
disposing an absorbent material within the first chamber;
disposing a manifold within the second chamber;
coupling a first port to the pouch, the first port being configured to fluidly couple the first chamber to a dressing for receiving fluids;
coupling a second port to the pouch, the second port being configured to fluidly couple the second chamber to a therapy unit for supplying reduced pressure; and
disposing a plurality of air bridges between the first chamber and the second chamber to provide fluid communication between the first chamber and the second chamber.

### Claim 2

An apparatus for storing liquid, the apparatus comprising:
a first chamber and a second chamber;
a first manifold disposed in the first chamber;
a second manifold disposed in the second chamber;
at least two air bridges coupling the first manifold and the second manifold; and
an absorbent disposed in the second chamber proximate to the second manifold.

### Claim 3 (depends on 2)

### Claim 5 (depends on 2)

The apparatus of claim 2, wherein the first chamber and the second chamber have a common wall.

### Claim 6 (depends on 2)

The apparatus of claim 2, wherein a first of the air bridges is disposed at a first extremity of the first manifold and a second of the air bridges is disposed at a second extremity of the first manifold.

### Claim 7 (depends on 2)

The apparatus of claim 2, further comprising a first port adapted to fluidly couple the first manifold to a reduced pressure source, and a second port adapted to fluidly couple the second manifold to a dressing; and wherein a first of the air bridges is disposed proximate to the first port and a second of the air bridges is disposed proximate to the second port.

### Claim 8 (depends on 2)

The apparatus of claim 2, wherein the first chamber comprises at least two adjoining cavities forming at least three extremities disposed along a periphery of the apparatus, and at least one air bridge is disposed at each of the three extremities.

### Claim 9 (depends on 2)

The apparatus of claim 2, wherein the first chamber comprises at least two orthogonal cavities forming at least three extremities disposed along a periphery of the apparatus, and at least one air bridge is disposed at each of the three extremities.

### Claim 10 (depends on 2)

The apparatus of claim 2, wherein the first chamber comprises at least four adjoining cavities forming at least four extremities disposed along a periphery of the apparatus, and at least one air bridge is disposed at each of the four extremities.

### Claim 11 (depends on 2)

The apparatus of claim 2, further comprising:
a first port adapted to fluidly couple the first manifold to a reduced pressure source, and a second port adapted to fluidly couple the second manifold to a dressing;
wherein the first chamber and the second chamber have a common wall;
wherein the first chamber comprises at least two adjoining cavities forming at least three extremities disposed along a periphery of the apparatus;
wherein at least one air bridge is disposed at each of the three extremities; and
wherein each air bridge comprises an aperture in the common wall that is a gas-permeable liquid barrier.

### Claim 12 (depends on 2)
