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.
Claims31
A wound dressing, ingredient delivery device or IV hold-down comprising:
- a handle defining an outer peripheral edge and an inner peripheral edge forming a window through the handle, the handle including a cut extending between and interconnecting the inner and outer peripheral edges;
- a polymeric film having a first and second side, at least a portion of said first side of the polymeric film being coated with an adhesive layer;
- the handle being adhered to said second side of said polymeric film, the continuity of contact between the handle and the underlying second surface of the polymeric film being interrupted at least in the vicinity of at least a portion of the edge of the handle by a plurality of deformations in the handle forming a plurality of regions wherein the handle is spaced-apart from the film to define a plurality of tunnels.
A wound dressing, ingredient delivery device or IV hold-down comprising:
- a handle defining an outer peripheral edge extending around substantially the entire handle;
- a polymeric film having a first and second side, at least a portion of the first side of the polymeric film being coated with an adhesive layer;
- the handle being adhered to the second side of said polymeric film, the continuity of contact between the handle and the underlying second surface of the polymeric film being interrupted at least in the vicinity of at least a portion of the edge of the handle by a plurality of discrete openings in the handle defining edges that do not connect to the outer peripheral edge of the handle.
A wound dressing, ingredient delivery device or IV hold-down comprising:
- a handle;
- a polymeric film having first and second sides, wherein at least a portion of the first side of the polymeric film is coated with an adhesive material;
- the handle being electrostatically adhered to the second side of the polymeric film without adhesive material, the handle defining an outer peripheral edge extending around substantially the entire handle, and including an enlarged opening through a central portion of the handle defining an inner edge that is spaced-apart from the outer edge, the handle including a first cut through the handle connecting the outer edge of the handle to the inner edge, and a plurality of second cuts through the handle disposed about the enlarged opening, and wherein the second cuts are not connected to either the outer peripheral edge or to the inner edge;
- and
- the handle comprises a layer of the non-conductive material and a layer of conductive metal material.
