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 and a stabilizing structure that may aid in wound closure.

An absorbent wound dressing (1) comprising a superabsorbent material (13) that is in fluid communication with the surface of a wound to which the dressing is applied when in use. The superabsorbent material (13) is enclosed in an envelope (14,15) having a wound-facing surface that is knitted or woven from a yarn comprising gelling fibres.

Embodiments of a negative pressure wound closure system and methods for using such a system are described. Certain disclosed embodiments facilitate closure of a wound by preferentially exerting a negative pressure on tissue. Some embodiments may utilize a collapsible sheet with a plurality of cells.

Disclosed is a wound pad with fibers and being provided with at least a first and a second discrete group of incisions, wherein each one of the discrete groups of incisions has at least a first incision, a second incision, and a third incision all extending from a common starting point to a respective end point, wherein each respective end point is spaced from the other end points.

A system, method, and apparatus are disclosed for dressing a wound. The apparatus comprises 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.

An absorbent structure, including a sensor system, can sense and measure the level of wetness contained within the absorbent structure as well as sense and measure environmental conditions. The sensor system may include passive RFID sensors or tags, RFID readers, antenna, a tuning module, a processing module, a memory module and a wireless communication module. The absorbent structure may further include two or more sensors, with a first sensor placed in a first area most likely to first be exposed to liquid and a second sensor spaced apart from the first sensor in an area likely to be exposed to liquid only after the absorbent structure has become more saturated.

A wound dressing comprising a breathable film, a fluid-absorption layer and a fluid-wicking layer, use of the wound dressing for treating or preventing wounds and/or for securement of a device that has been at least partially inserted in the skin, and methods of making said wound dressings.

A method and apparatus are disclosed for dressing a wound. The apparatus comprises an absorbent layer for absorbing wound exudate, a liquid impermeable, gas permeable filter layer over the absorbent layer, a cover layer comprising at least one orifice and a first liquid and gas permeable transmission layer underlying the absorbent layer. The transmission layer is in fluid communication with the filter layer.

A wound treatment system for treating a surgical wound includes a dressing. The dressing includes a manifold layer and an absorbent pouch assembly coupled to the manifold layer. The absorbent pouch assembly includes an absorbent material contained within a pouch. The dressing also includes a drape coupled to the absorbent pouch assembly and configured to be sealable over the surgical wound. The absorbent pouch assembly is positioned between the drape and the manifold layer. The wound treatment system also includes a pump fluidly communicable with the dressing and configured to draw a negative pressure at the manifold layer. The manifold layer is configured to substantially prevent medial collapse of the manifold layer under the negative pressure.

A dressing includes a hydrophilic foam layer having a longitudinal central axis configured to overlay the incision, a drape coupled to an outwardly-facing side of the hydrophilic foam layer, a first row of superabsorbent material positioned on the outwardly-facing side of the hydrophilic foam layer, and a second row of superabsorbent material positioned on the outwardly-facing side of the hydrophilic foam layer. The first row and the second row are spaced laterally apart from, and on opposite sides of, the longitudinal central axis. The drape includes a first window aligned with the first row and a second window aligned with the second row. The first window and the second window include a film, different from the drape, configured to facilitate evaporation therethrough.
