Abstract
Abstract An adhesive dressing comprises a backing layer (2) having over one surface a pressure sensitive adhesive layer (3). A removable protector (4) covers the adhesive layer and a handling means (5) is present at one edge of the backing layer. The dressing has a fold (8) in a direction substantially parallel to the handling means so that the backing layer is on the outside of the fold. The portion of the dressing beyond the fold is releasably attached to the portion of the dressing before the fold preferably by means of a double-sided tape (10). In use the protector may be peeled from the adhesive layer up to the fold when peeling will stop. The protector and handling means may be used to position the dressing on the skin. Application of a further force peels the protector from the rest of the adhesive surface. The dressings are for use as I.V. dressings.
