    Abstract: This disclosure includes wound dressings and systems for effluent management of topical wound therapy and related methods. Some devices, which are configured to dilute therapeutic gas effluent flowing from a dressing, comprise a therapeutic gas source configured to provide therapeutic gas to the dressing; a container comprising a sidewall that defines a chamber configured to receive therapeutic gas effluent from the dressing; a negative pressure source configured to be coupled to the container such that the negative pressure source can be activated to draw fluid from the dressing through the chamber of the container; and a diluent gas source configured to deliver a diluent gas to dilute therapeutic gas effluent before the therapeutic gas effluent enters the negative pressure source.

    Abstract: A dressing for treating a tissue site may include a base layer, a sealing member, a first and a second wicking layer, and an absorbent layer. The base layer may have a plurality of apertures and may be adapted to cover the tissue site. The sealing member and the base layer may define an enclosure. The first and the second wicking layer may each be disposed in the enclosure with the absorbent layer positioned between the first and the second wicking layer. A conduit comprised of an absorbent material that is vapor permeable and liquid impermeable may be in fluid communication with the dressing for providing reduced pressure to the dressing. Other dressings, systems, and methods are disclosed.

    Abstract: Systems, methods, and apparatuses are presented that facilitate the provision of reduced pressure to a tissue site by using a delivery-and-fluid-storage bridge, which separates liquids and gases and provides a flow path for reduced pressure. In one instance, a delivery-and-fluid-storage bridge includes a delivery manifold for delivering reduced pressure to a treatment manifold at the tissue site and an absorbent layer proximate the delivery manifold adapted to receive and absorb liquids. The delivery manifold and the absorbent layer are encapsulated in an encapsulating pouch. A first aperture is formed proximate a first longitudinal end of the delivery-and-fluid-storage bridge for fluidly communicating reduced pressure to the delivery manifold from a reduced-pressure source, and a second aperture is formed on a patient-facing side of the delivery-and-fluid-storage bridge. Reduced pressure is transferred to the tissue site via the second aperture. Other systems, apparatuses, and methods are disclosed.

    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.
