COMPOUND HYDROGEL WOUND DRESSING

摘要

The compound hydrogel wound dressing of the invention consists of an absorbent hydrogel layer, a mesh or scrim embedded in the hydrogel layer and an oxygen- and vapour-permeable outer or backing layer arranged to overlie the mesh reinforced hydrogel layer in use. The mesh includes winglets which extend beyond the peripheral boundary of the hydrogel layer. The undersurface of the outer layer is coated, either adjacent the periphery of the outer layer or over the entire surface, with a medical-grade, hypoallergenic pressure-sensitive adhesive. The arrangement is such that when the mesh reinforced hydrogel layer is applied over a wound the winglets of the mesh adhere to the coated undersurface of the backing layer. When the wound dressing is to be removed, the backing layer is peeled away from the patient's skin, drawing the mesh and hydrogel layer away from the wound.
