    Abstract: In one example embodiment, a dressing connector is described that provides a first fluid path between a first connector and a second connector, and a second fluid path between a third connector and a fourth connector. A liquid barrier may be disposed in the first fluid path. The first fluid path and the second fluid path are generally exposed to an exterior surface of the dressing connector. In some embodiments, a tube may also be bonded to the third connector to provide a third fluid path between the dressing connector and another component. In more particular embodiments, the liquid barrier may be a filter, such as a hydrophobic bacterial filter, a sintered polymer filter, and/or a charcoal filter.

    Abstract: Systems, methods, and dressing are presented for treating a tunnel wound on a patient. In one instance, a reduced-pressure, tunnel-wound dressing includes a longitudinal core member formed from a closed-cell foam that is surrounded by a first longitudinal concentric member formed from a manifolding material. When subjected to reduced pressure, the longitudinal core member expands and the first longitudinal concentric member compresses. These actions create intimate contact between the tunnel wound and the dressing, oppose collapse of the tunnel, and when reduced pressure is removed provide clearance to remove the dressing. Other embodiments are presented.

    Abstract: A system is illustratively described herein that generally comprises a vacuum chamber, an ambient pressure chamber, a valve configured for unidirectional flow from the vacuum chamber to the ambient pressure chamber during a charging stroke, and a liquid filter configured to retain liquid in the pump. In some embodiments, the liquid filter is configured to retain liquid in the vacuum chamber during the charging stroke. In other embodiments, it may be configured to retain liquid in the ambient pressure chamber during an operating stroke. In more particular embodiments, a piston may be disposed between the vacuum chamber and the ambient pressure chamber, a passage may fluidly couple the vacuum chamber and the ambient pressure chamber, and the valve can be configured to control fluid flow through the passage. Additionally, a lumen may couple the vacuum chamber to a dressing to deliver negative pressure to the dressing in some illustrative embodiments.

    Abstract: A bodily fluid collection system includes a reduced pressure treatment unit for providing reduced pressure to a fluid collection system through a canister having a container with an inlet adapted to be fluidly coupled to the fluid collection system, an outlet adapted to be connected to a source of reduced pressure, and an absorptive lamination disposed within the container. The absorptive lamination may be formed from a plurality of absorptive layers and wicking layers interleaved between the absorptive layers that collectively manifold bodily fluids from a tissue site into and throughout the absorptive lamination to trap and collect the bodily fluids. The container expands as the absorptive lamination swells with the bodily fluid being collected.

    Abstract: A wound fluid collection system includes a canister with a chamber fluidly connected to a wound dressing in a tissue site through an inlet and also fluidly connected to a reduced pressure source through an outlet. At least a portion of the canister is collapsible and yet can be maintained in an extended state when exposed to subatmospheric pressure. The canister is releasably attachable to a supporting member.
