Disclosed herein is a wound dressing and composition comprising a backing layer having disposed thereon a discontinuous layer of hydrogel, wherein the discontinuous layer of hydrogel is in the form of discrete islands of hydrogel on the backing layer. Methods of treating a wound using the dressing or the composition are also disclosed. Methods of forming the dressing or the composition are also disclosed.

Flexible hydrogel wound dressings

The invention provides a layered composition comprising: a first layer comprising a first material, wherein the first material comprises a gel material; a second layer comprising a second material, wherein the second material is harder is than the first material; and a third layer comprising a third material, wherein the third material has a lower tensile modulus than the second material, wherein the second layer is disposed between the first and third layers. The composition may be used in a wound dressing, in which preferably the first layer is in fluid flow communication with the wound.

Multilayer compositions and dressings

A dressing for covering a wound of a patient comprises a sheet member adapted to be adhered to the patient's skin in use to provide an airtight seal around the wound, wherein the skin-adhesion is provided by a hydrogel layeron the skin-facing face of the sheet member, wherein the sheet member defines in use a substantially enclosed spaceabove the wound, and wherein a plurality of mutually spaced-apart flutter valves formed by holesin a thin filmoverlying an upper face of a layerof the sheet member permit one-way air, blood and/or other fluid flow communication from the spaceabove the wound to the exterior of the dressing.
