DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a tab member especially for use as a "nontouch" grip for applying a dressing comprising an adhesive layer and optionally a release liner to the skin without touching the adhesive layer, a method for manufacturing such tab member and a dressing comprising the tab member.
2. Description of Related Art
As it is commonly known thin wound dressings are difficult to apply to wounds, especially in curved areas, without wrinkling or sticking to themselves or to the users, e.g., a nurse or assisting persons fingers. It is desirable to apply all kinds of dressings without touching the adhesive layer in order to avoid reducing the adhesiveness. Because of the risk of introducing bacteria to the wound it is desirable to apply a dressing to a patient's skin without touching the surface of the dressing that is to come into contact with the skin. The prior art discloses several methods for facilitating handling of a wound dressing.
GB Patent APPLICATION 2,128,479 describes a surgical dressing having two release sheets, each covering half of the dressing and having a free edge curved at the center of the dressing. As the curved edges of the release sheets are peeled back, the center of the dressing is applied over a catheter or to a wound, followed by the ends, thereby preserving sterility by eliminating the need to touch the adhesive surface of the dressing.
U.S Pat. No. 4,753,232 discloses a "handle" portion along one edge of the dressing. After the dressing is applied, the handle may be removed by tearing, or it may carry an adhesive coating so that it may be adhered to the skin of the patient.
Another known method of avoiding contact with the edges of a bandage by fingers or forceps is disclosed in U.S. Pat. No. 4,646,731 disclosing a bandage which is coated with an adhesive and the edges of which are protected by a pair of folded V-shaped tabs. After removing the backing sheet from the bandage, one tab is removed and the corresponding end of the bandage is applied to the skin. The second tab is grasped and removed as the entire length of the bandage is then applied.
European Patent Application No. EP 0 168 174 discloses a dressing comprising a first adhesive contact layer and an inner surface of a thin film backing. A release layer covering the first adhesive layer is removed prior to application of the dressing, and the film backing preferable has an edge portion free of adhesive to facilitate the removal of the release layer from the dressing without touch conlaminating the underside of the dressing. A relatively rigid carrier section is secured to the outer surface of the film backing by a second adhesive layer, and the carrier section includes rigid handles keeping the dressing extended during application of the dressing to a skin surface and prevents the dressing from curling or folding up.
U.S. Pat. No. 4,744,355 discloses a solution to a problem associated with excessive peeling force during removal of backings from wound dressings by dividing the release liner in halves. A wound dressing is disclosed in which the release liner halves are each divided into a release liner main body and a release liner edge strip. The release liner main body overlaps a portion of the edge strip and the two are secured to each other by a flexible hinge. As the release liners are pulled away from the wound dressing, the hinge means are employed, thus reducing the peeling force.
U.S. Pat. No. 5,106,629 discloses a dressing having a thin transparent film layer, a stable backing layer over the outer surface of the transparent layer, and a release liner. The backing layer and the release liner each have a corner tab to facilitate the peeling of each from the transparent layer.
Published EP APPLICATION No. EP 0 630 629 discloses a flexible wound dressing product that includes a thin-film layer, an adhesive layer, a backing layer which may be porous, an optional support layer, an optional release liner, and a hydrogel material without the use of an
