Wound dressing, ingredient delivery device and IV hold-down, and method relating to same
View Patent ↗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.
1. 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.
2. The device of claim 1 , wherein:
the handle includes a cut extending between and interconnecting the perimeter and the inner edge of the handle that defines the enlarged opening.
3. The device of claim 2 , wherein:
the tab is disposed immediately adjacent the cut.
4. The device of claim 3 , wherein:
the inner edge of the handle defines first and second portions on opposite sides of the tab, and the tab defines an edge that projects into the enlarged opening relative to the first and second portions, and wherein the edge of the tab forms a corner at an intersection with the first portion of the inner edge, and wherein the cut extends from the corner to the perimeter.
5. The device of claim 4 , wherein:
the cut is defined by first and second end edges of the handle extending along opposite sides of the cut, wherein the first end edge continues past the corner to form an edge of the tab adjacent the corner.
6. The device of claim 5 , wherein:
the first and second end edges are linear.
7. The device of claim 5 , wherein:
the corner defines a corner point, and the first end edge intersects the perimeter to define an intersection point, and wherein the intersection point is spaced apart from an imaginary line extending through the corner point, and wherein the imaginary line is perpendicular to the first portion of the inner edge of the corner.
8. The device of claim 4 , wherein:
the edge of the tab at the corner and the first portion of the inner edge at the corner are both linear.
9. The device of claim 1 , wherein:
the tab includes substantially parallel opposite edge portions and a convexly curved end edge extending between the opposite edge portions.
10. 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.
11. The device of claim 10 , wherein:
the tab defines a center line extending in the first direction, and wherein the tab includes opposite edge portions that are mirror images of one another.
12. The device of claim 11 , wherein:
a first one of the opposite edge portions of the tab intersects the inner peel point.
13. The device of claim 10 , wherein:
the tab is defined by a tab portion of the inner peripheral surface, the tab portion including a convexly curved portion.
14. The device of claim 10 , wherein:
the tab includes linear opposite edges that are parallel to one another and parallel to the first direction.
15. The device of claim 10 , wherein:
the obtuse angle is between about 120 degrees and about 150 degrees.
