The wound dressing described herein includes a backing layer, absorbent layer, and foam layer. The wound dressing also includes one or more visual indicators. The visual indicators are substantially non-visible in their initial, dehydrated state. As the visual indicators absorb fluid they swell and become visible. The visual indicators enable a caregiver to know when the wound dressing has reached, or is about to reach, its fluid capacity.

A wound care device for debriding a wound, said device is in the form of a foam pad with two layers of different foams. At one surface of the device is provided a pattern of grooved at the central portion. The grooves improve the ability of removing and collecting debris from a wound during cleaning of such.

Systems and methods for managing fluid absorption from a tissue site are described. A dressing having an absorbent is positioned proximate the tissue site to receive fluid from the tissue site. A reduced-pressure source is fluidly coupled to the dressing and supplies reduced pressure to the dressing. The reduced pressure is periodically decreased to distribute fluid in the absorbent and managed fluid absorption. The system includes a reduced-pressure source and a container having an upstream layer, a downstream layer, and an absorbent between the upstream layer and the downstream layer. The system also includes a sealing member for forming a therapeutic environment having the container and a controller configured to operate the reduced pressure source to intermittently supply reduced pressure to the therapeutic environment and periodically decrease the reduced pressure in the therapeutic environment.

Flexible polyurethane (PU) material which comprises a flexible hydrophilic polyurethane foam porous matrix comprising two matrix faces and therebetween a structural matrix framework defining a network of cells, having a cell network surface and therein a network of pores and a powder charge comprising one or more additives loaded in said structural matrix framework wherein said material is a foamed polymer of a system comprising an isocyanate prepolymer or monomer phase and an aqueous phase, wherein said system comprises one or more slurry phases or solid concentrates of said powder charge, or an insoluble portion thereof, as said isocyanate phase or part thereof and/or as said aqueous phase or part thereof and/or in a carrier liquid phase; and/or comprising a powder charge of silver salt loaded in said structural matrix framework in a population of silver salt particles defined by particle size distribution about a mean particle size of greater than or equal to 1 micron, said material comprising silver salt in population of particles corresponding to silver salt comprised in powder charge pre-loading; methods for manufacture thereof, systems for control thereof, devices containing said material and methods for treatment therewith and uses thereof.

An elongate wound dressing for packing a wound is described, the wound dressing being substantially planar and having a first longitudinal edge comprising at least one curved edge portion which is curved in the plane of the wound dressing.

The invention provides a wound dressing, which includes a 1 to 12 mm thick layer of absorbent non-woven fibre material between 150 and 1200 grams per square meter, which layer includes a mixture of viscose fibres and polyester fibres which more viscose than polyester, and of which the fines of the viscose is between 1.5 and 3 dtex and the fines of the polyester is between 2 and 3 dtex.

An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a healing manner while also limiting the formation of adhesions that would prevent the removal of the dressing. The dressing comprises a layer of porous foam material enclosed by sheets of elastomeric material punctuated by a number of appropriately placed holes. Multiple layers of porous foam may also be used. A suction tube connector is provided on an upper surface of a layer of foam for connection to a negative pressure source. At least one layer of foam is enclosed in elastomeric material and is placed in direct contact with the tissue within the open wound. Fluids are drawn by negative pressure through the holes positioned in the elastomeric envelope and through the foam.

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.

Some embodiments have a pump assembly mounted to or supported by a dressing for reduced pressure wound therapy. The dressing can have visual pressure, saturation, and/or temperature sensors to provide a visual indication of the level of pressure, saturation, and/or temperature within the dressing. Additionally, the pump assembly can have a pressure sensor in communication with the flow pathway through the pump, and at least one switch or button supported by the housing, the at least one switch or button being accessible to a user and being in communication with the controller. The pump assembly can have a controller supported within or by the housing, the controller being configured to control an operation of the pump. The pump can be configured to be sterilized following the assembly of the pump such that all of the components of the pump have been sterilized.

Described herein are dressings for incision management comprising a dressing layer that comprises: an elastic layer such as a hydrocolloid or foam layer; and an absorbent layer coupled, for example by lamination, to the elastic layer and which comprises: (i) from about 45% to about 90% carboxymethyl cellulose fibers; and (ii) from about 10% to about 55% elastic reinforcing fibers. Though the elastic layer may be substantially elastically deformable under tissue treatment conditions and the absorbent layer may be not elastically deformable under tissue treatment conditions, the coupling together of the elastic layer and the absorbent layer may result in a dressing layer, and advantageously a dressing, that is substantially elastically deformable under tissue treatment conditions. Methods for manufacturing such dressings and of eliminating, minimizing, or reducing edema using such dressings are also described herein.
