The present invention relates to wound dressings. In particular, the invention relates to antimicrobial wound dressings, methods of making the same and uses of the same. The wound dressing of the present invention comprises a wound contact layer and an absorption layer, wherein the wound contact layer comprises at least one antimicrobial agent and wherein the lateral wicking rate of the wound contact layer is the same or higher than the lateral wicking rate of the absorption layer. The wound dressing of the present invention provides an absorbent, conformable and anti-microbial medical device that may be used in a variety of medical situations, including post and/or pre-operative.

The present invention relates to wound dressings. In particular, the invention relates to antimicrobial wound dressings, methods of making the same and uses of the same. The wound dressing of the present invention comprises a wound contact layer and an absorption layer, wherein the wound contact layer comprises at least one antimicrobial agent and wherein the wound contact layer is compressed and/or wherein the wound contact layer has a density of greater than 0.06 g/cm.sup.3. The wound dressing of the present invention provides an absorbent, conformable and anti-microbial medical device that may be used in a variety of medical situations, including post and/or pre-operative.

This disclosure relates to a wound care device which contains capillary force one-way pumps that are capable of transporting fluid, such as wound exudate, away from a wound site to the opposite side of the wound care device, which functions as a segregated fluid reservoir. This fluid transport mechanism generally aids in reducing wound maceration by removing excess wound fluid and the protease enzymes and infectious bacteria contained within the wound fluid. The wound care device performs this function, often times for multiple days, without the loss of the physical integrity of the wound care device. In addition to providing a uni-directional fluid transport mechanism, the wound care device contains a perforated adhesive layer.

The present application is concerned with an improved wound dressing for use in the treatment of skin wounds with some level of exudation, especially for use in those wounds which are infected or under risk of being infected by microorganisms.

A wound dressing includes a hydrophilic foam layer, a drape layer, superabsorbent projections, and printed indicators. The hydrophilic foam layer is configured to engage a wound bed and has a first side and a second side, the second side configured to face the wound bed. The drape layer has a first side and a second side, the second side configured to face the first side of the hydrophilic foam layer. The plurality of non-contiguous superabsorbent projections are fixed to and extend from the first side of the hydrophilic foam layer towards the second side of the drape layer. The one or more non-contiguous printed indicators surround one or more of the plurality of superabsorbent projections.

A dressing includes an evaporative film layer having a wound-facing side and a non-wound¬ facing side. The evaporative film layer has a high moisture vapor transfer rate. The dressing includes a carrier film layer coupled to the non-wound-facing side of the evaporative film layer. A plurality of holes extends through the carrier film layer. The dressing includes a superab sorbent layer coupled to the wound-facing side of the evaporative film layer and a wicking layer coupled to the superab sorbent layer. The superab sorbent layer is positioned between the wicking layer and the evaporative film layer. The wicking layer is configured to wick fluid from a wound, the superab sorbent layer is configured to absorb fluid from the wicking layer, and the evaporative film layer and the carrier film layer allow evaporation of fluid from the superabsorbent layer through the holes. The carrier film layer provides structural support to the evaporative film layer.

Disclosed herein are several embodiments of a wound treatment apparatus employing glue on the backing layer of a wound dressing. In some embodiments, the glue limits saturation of an absorbent layer beneath the backing layer.

The invention relates to a dressing (1) for treating wounds in damp or wet situations, comprising: a) a suction/rinsing body (2) which is supplied by the manufacturer with a saline aqueous solution, particularly a Ringer's solution, said solution preferably containing a substance exhibiting an antimicrobial effect, b) a planar carrier material (3) which is arranged on the side of the suction/rinsing body (2) that faces away from the wound and which projects over said suction/rinsing body (2) such that an edge extending around all sides of the suction/rinsing body (2) is formed, said edge being provided, with a layer of a skin-compatible silicone adhesive (4) on the side facing the wound, and c) a first protective layer (5) that covers the layer of a skin-compatible silicone adhesive (4) on the side facing the wound, characterized in that the wound dressing (1) comprises a second protective layer (6) arranged on the side of the carrier material (3) facing away from the wound, wherein both the first and the second protective layers (5,6) fully project beyond the carrier material (3), wherein the first protective layer (5) forms an opening that leaves the suction/rinsing body (2) uncovered, and wherein the first and second protective layers (5,6) protect the layer of a skin-compatible silicone adhesive (4) from contact with liquid and steam.

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.
