Abstract: A sealing drape may be suitable for use with a reduced-pressure treatment system for treating a tissue site. The sealing drape may have an interior surface adapted for positioning adjacent to a peripheral surface of the tissue site. The sealing drape may include a sealing material and an absorbent material. The sealing material may be hydrophobic and substantially free of hydrophilic components. Further, the sealing material may be positioned between the interior surface of the sealing drape and the absorbent material. The sealing drape may be used with a manifold for positioning at the tissue site, a reduced-pressure interface, and a reduced-pressure source. Methods of manufacture and treatment are also disclosed.

Abstract: Systems, methods, and dressings for treating a linear wound, such as an incision, on a patient are presented. The systems, dressings, and methods involve a sealed wound dressing assembly that helps form a fluid seal around the linear wound while simultaneously encompassing a subcutaneous delivery conduit to deliver fluid to or from a subcutaneous tissue site. In one instance, a reduced-pressure interface is used to allow the subcutaneous delivery conduit to pass through tissue at or near the linear wound and through a wound dressing assembly to a drainage receptacle.

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 periphery surrounding a central portion and a plurality of apertures disposed through the periphery and the central portion. At least one of the apertures in the periphery may be positioned at an edge of the periphery, and may have an interior exposed at the edge. 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. Other dressings, systems, and methods are disclosed.

Abstract: A wound therapy system includes a wound dressing fluidly connected to a fluid canister. The fluid canister is attached to a canister receiving attachment of a housing structure. A pump is fluidly coupled to the canister and is configured to draw a negative pressure within an interior of the canister. A controller of the wound therapy system is configured to operate the pump to apply a vacuum to the interior of the canister and to obtain one or more measurements representative of at least one or a flow rate of air that is exhausted from the canister interior, a pressure within the canister interior and pump ripple. The controller is configured to estimate the volume of the canister based on the comparison of the measured parameters against model data stored by the controller that is representative of the operation of the therapy system with canisters of varying volumes.

Abstract: Dressings, systems, and methods for treating a tissue site on a patient involve allowing liquids from the tissue site or a priming fluid to evaporate and exit the dressing through a liquid-impermeable, vapor-permeable membrane. The dressing is able to process more liquids than would otherwise be possible without evaporation and potentially to create reduced pressure. Other dressings, systems, and methods are disclosed.

Abstract: A system for treating a tissue site of a patient includes a dressing filler adapted to be positioned at the tissue site. The dressing filler includes a porous substrate having at least one compressed region and at least one expanded region. The compressed region of the porous substrate is held in a compressed state by a first coating capable of dissolving in the presence of a fluid, and the expanded region of the porous substrate is held in an expanded state by a second coating.

Abstract: Systems and methods for a reduced-pressure interface for connecting a multi-lumen conduit to a distribution manifold. The interface includes a housing having a flange portion and a cavity wall portion. The cavity wall portion forms a cavity having a tissue-facing cavity opening. The interface further includes an attachment device, a conduit port, and a multi-lumen conduit. The attachment device is coupled to a tissue-facing side of the flange portion for coupling the housing to a sealing member. The conduit includes a distal end and a proximal whereby the distal end extends through a conduit aperture and past the cavity wall portion into the cavity. The conduit further includes a primary lumen and a plurality of sensing lumens. The primary lumen and the plurality of sensing lumens extend from the proximal end of the conduit to the distal end. The conduit is adapted to contact the distribution manifold.

Abstract: Systems, kits, methods of manufacturing, and a sealing member for creating a sealed space are described. The sealing member can include a film layer and a first adhesive layer coupled to the film layer. The sealing member can also include a second adhesive layer coupled to the first adhesive layer. A plurality of apertures may extend through the second adhesive layer. Each aperture can expose at least a portion of the first adhesive layer through the second adhesive layer. A plurality of polymer particles may be disposed in the first adhesive layer. The polymer particles can be configured to dissolve in response to interaction with a switching solution.

Abstract: Systems, methods, and connectors are provided that introduce a working gas at certain times into a reduced-pressure dressing into order to break or avoid vacuum locks in the conduits removing fluids. In one instance, a reduced-pressure connector includes a connector body for applying a reduced pressure to the tissue site. The connector body is formed with a venting port, a body conduit, and a receptacle to receive a reduced-pressure delivery conduit. The reduced-pressure connector includes a flexible member coupled to the connector body over the venting port. The flexible member is formed with at least one venting aperture. The flexible member is biased away from the venting port and is configured to collapse and seal the venting port under a reduced pressure greater than a threshold pressure. Other systems, apparatuses, and methods are disclosed.
