Described is a negative wound therapy (NPWT) dressing that includes a backing layer and an adhesive skin contact layer, the adhesive skin contact layer being configured to detachably adhere the dressing to a dermal surface, wherein the backing layer includes a coupling member. The coupling member includes a tubing configured to connect the dressing to a negative pressure source and to a remote fluid collector.

A controlled oxygen dressing includes a flexible drape that is selectively permeable to air and is adhere to skin to define a first volume around a tissue site. A cover layer, impermeable to air, is sealed to the drape to thereby define a second volume between the cover layer the drape. An oxygen scavenger is arranged in the second volume and consumes oxygen in the second volume, which produces an oxygen concentration differential between the first and second volumes, This differential causes oxygen to diffuse through a covered portion of the drape, from the first volume to the second volume, thus decreasing the amount of oxygen in the first volume. Oxygen entering into the first volume from the surrounding environment diffuses through a non-covered portion of the drape. Therefore, an area of the cover layer can be selected to produce a desired level of oxygen in the first volume.

A wound dressing is disclosed, the wound dressing comprising a first adhesive layer with a proximal surface configured for attachment of the wound dressing to the skin surface of a user; an absorbent core layer; an electrode assembly comprising a plurality of electrodes arranged on a distal side of the absorbent core layer, the electrode assembly comprising a plurality of sensor points distributed along a distal surface of the absorbent core layer; and a top layer on a distal side of the electrode assembly.

A dressing includes a drape, a metal coating provided on a skin-facing surface of the drape, a pressure-sensitive adhesive provided on a lower surface of the metal coating, and a gasket having a frame shape. The drape is a thin film. The gasket includes an inner edge defining an opening and an outer edge offset inwardly from an outer periphery of the drape. The gasket is in contact with the metal coating and leaves a margin of pressure-sensitive adhesive around the gasket.

Disclosed herein are several embodiments of a negative pressure appliance and methods of using the same in the treatment of wounds. Some embodiments are directed towards wound dressings comprising a liquid and gas permeable transmission layer, an absorbent layer for absorbing wound exudate, the absorbent layer overlying the transmission layer, a gas impermeable cover layer overlying the absorbent layer and comprising a first orifice, wherein the cover layer is moisture vapor permeable. Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters.

A dressing including a film which is impermeable to fluids and permeable to water vapor, and the entire surface of which is covered by a perforated reinforcement coated with a medically acceptable adhesive which is the same or different on each of the faces thereof, the face opposite to the face in contact with the impermeable film of an adhesive being partially covered by an absorbent pad, The dressing further includes a layer for distributing the fluids which is positioned between the impermeable film and the perforated reinforcement.

Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters.

Embodiments disclosed herein are directed to negative pressure treatment systems and wound dressing systems, apparatuses, and methods that may be used for the treatment of wounds. In particular, some embodiments are directed to improved wound dressings comprising an obscuring layer that may hide fluid contained therein. Some embodiments may further comprise one or more viewing windows disposed therethrough so as to enable monitoring or examination of fluids contained therein.

A wound dressing is disclosed, the wound dressing comprising a first adhesive layer with a proximal surface configured for attachment of the wound dressing to the skin surface of a user; an absorbent core layer; an electrode assembly comprising a plurality of electrodes arranged on a distal side of the absorbent core layer, the electrode assembly comprising a plurality of sensor points distributed along a distal surface of the absorbent core layer; and a top layer on a distal side of the electrode assembly.

A wound treatment system for includes a wound dressing with a moisture vapor permeable backing layer and a moisture management system. The moisture management system includes a film layer, and a spacer assembly configured to be supported atop the upper surface of the wound dressing. Upon assembly, a flow path is defined between an upper surface of the wound dressing and a lower surface of the film layer. An air displacement device is configured to generate a forced airflow through the flow path. As air flows through the flow path, the dry air accelerates the diffusion and evaporation of fluid from the wound dressing, increasing the fluid capacity of the wound dressing.
