Abstract
An adhesive dressing comprises a backing layer having over one surface a pressure sensitive adhesive layer. A removable protector covers the adhesive layer and a handling means is present at one edge of the backing layer. The dressing has a fold 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. 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.

An adhesive dressing comprising a backing layer having over a surface thereof a pressure sensitive adhesive layer, a removable protector having a release coated surface which covers the adhesive layer and handling means at one edge of the backing layer, the dressing having a fold in a direction parallel to the handling means with the backing layer on the outside of the fold and means releasably attaching a portion of the dressing beyond the fold to a portion of the dressing before the fold, the protector extending beyond the edge of the backing film at the edge opposite the handling means, and wherein the extended portion of the protector is folded so that a portion of its release coated surface contacts an adhesive surface of the means releasably attaching the portion of the dressing beyond the fold to the portion of the dressing before the fold.
A method of treating a patient by applying thereto an adhesive dressing comprising a backing layer having over one surface thereof a pressure sensitive adhesive layer, a removable protector having a release coated surface which covers the adhesive layer and handling means at one edge of the backing layer, the dressing having a fold in a direction parallel to the handling means with the backing layer on the outside of the fold and means releasably attaching a portion of the dressing beyond the fold to a portion of the dressing before the fold the protector extending beyond the edge of the backing film at the edge opposite the handling means, and wherein the extended portion of the protector is folded so that a portion of its release coated surface contacts an adhesive surface of the means releasably attaching the portion of the dressing beyond the fold to the portion of the dressing before the fold, which method comprises peeling the protector from the adhesive layer up to the fold, applying the adhesive surface to the skin and then peeling off the remainder of the protector.
A method of retaining an indwelling catheter on the body of a patient by employing an adhesive dressing which comprises a backing layer having over one surface thereof a pressure sensitive adhesive layer, a removable protector having a release coated surface which covers the adhesive layer and handling means at one edge of the backing layer, the dressing having a fold in a direction parallel to the handling means with the backing layer on the outside of the fold and means releasably attaching a portion of the dressing beyond the fold to a portion of the dressing before the fold the protector extending beyond the edge of the backing film at the edge opposite the handling means, and wherein the extended portion of the protector is folded so that a portion of its release coated surface contacts an adhesive surface of the means releasably attaching the portion of the dressing beyond the fold to the portion of the dressing before the fold, which method comprises peeling the protector from the adhesive layer up to the fold, applying the exposed adhesive surface to the skin surrounding the catheter and then peeling off the remainder of the protector.
