Abstract
An adhesive device used as a wound dressing, ingredient delivery device or IV hold-down in which inadvertent edge release of these devices along the periphery of the polymeric film layer is minimized when the handling layer, which is adhered to the polymeric film layer, is removed after application of the polymeric film layer to the patient.
Claims15
A wound dressing, ingredient delivery device or IV hold-down comprising:
- a handle defining a perimeter and an inner peripheral edge defining an enlarged opening through the handle, and wherein the handle includes a tab projecting into the enlarged opening, the handle having an undersurface with an adhesive coating on the undersurface, the tab having an underside that is not coated with adhesives;
- a polymeric film releasably adhered to the adhesive coating on the undersurface of the handle adjacent the perimeter and having a central portion extending across the enlarged opening;
- and wherein:
- the tab overlies at least a portion of
- the central portion of the polymeric film.

A wound dressing, ingredient delivery device or IV hold-down comprising:
- a handle member having a lower surface, an outer peripheral edge, and an inner peripheral edge defining a central opening through the handle member, wherein portions of the inner and outer peripheral edges define an elongated portion therebetween, wherein the elongated portion extends in a first direction, the handle member further including a cut extending between and intersecting the inner and outer peripheral edges and defining inner and outer peel points at the intersections of the cut with the inner and outer peripheral edges, respectively, and wherein the handle member defines a linear peel line extending through the inner and outer peel points, and wherein the peel line defines an obtuse angle relative to the first direction that is substantially greater than 90 degrees, the handle member defining a tab that extends into the central opening in the first direction adjacent the cut;
- a layer comprising a first adhesive disposed on substantially the entire lower surface of the handle member except at the tab;
- a polymeric film having an upper surface adhered to the lower surface of the handle member by the first adhesive;
- a release liner adhered to a lower surface of the polymeric film by a second adhesive;
- and wherein:
- the first adhesive adheres the handle member to the polymeric film more aggressively than the second adhesive adheres the release liner to the polymeric film, such that the release liner can be peeled off the lower surface of the polymeric film without peeling the handle off the upper surface of the polymeric film;
- and
- the second adhesive adheres the lower surface of the polymeric film to a skin of a patient more aggressively than the first adhesive adheres the handle member to the upper surface of the polymeric film, such that the handle member can be peeled away from the polymeric film when the polymeric film is adhered to the skin of the patient without peeling the polymeric film away from the skin.
