Abstract

The disclosed medical dressing has a dressing body and a flap. The dressing body has a first major surface and opposite second major surface containing a skin-contact adhesive. The flap has a fixed end integrally connected to the dressing body and a movable free end. The second major surface of the flap has a securing adhesive for contact with the first major surface of the dressing body.

First claim

What is claimed is:

1. A medical dressing comprising:
a dressing body comprising:
a first major surface,
a second major surface, opposite the first major surface, comprising a skin-contact adhesive;
a transparent window;
a perimeter surrounding a central portion of the dressing body; and
a recess extending from the perimeter inward to the central portion of the dressing body; and

a flap comprising:
a first major surface,
a second major surface, opposite the first major surface,
a fixed end integrally connected to and provided by a portion of the dressing body, and
a free end,

wherein the second major surface of the flap comprises a securing adhesive for contact with the first major surface of the dressing body;
wherein the dressing body has a proximal end with the flap and recess and a distal end with the transparent window;
wherein the moveable free end is moveable with respect to the dressing body to position in overlapping relationship with and in contact with the first major surface of the dressing body and spanning the recess.

2. The medical dressing of claim 1 , wherein the adhesion of the skin-contact adhesive is less than the adhesion of the securing adhesive.

3. The medical dressing of claim 1 , wherein the adhesion between the second major surface of the dressing body and the skin surface is less than the adhesion between the second major surface of the flap and the first major surface of the dressing body.

4. The medical dressing of claim 1 , wherein the second major surface of the flap comprises a removable release liner covering the securing adhesive.

5. The medical dressing of claim 1 , wherein the skin-contact adhesive comprises a silicone adhesive and wherein the securing adhesive comprises an acrylate adhesive.

6. The medical dressing of claim 1 , wherein the flap is formed by a portion of the dressing body, wherein the dressing body includes a base layer and a top layer, and wherein the flap is formed by the top layer of the dressing body to secure at least a portion of a medical article between the top layer and the base layer of the dressing body.

7. The medical dressing of claim 6 , wherein the top layer comprises a first major surface and a second major surface, wherein the second major surface of the top layer is positioned to be coupled to a first major surface of the base layer, wherein a second major surface of the base layer is configured to be coupled to skin, and wherein the second major surface of the base layer includes a silicone adhesive and the second major surface of the top layer includes an acrylate adhesive.

8. The medical dressing of claim 6 , wherein the flap is separated from a remainder of the top layer by a living hinge, and wherein the living hinge is positioned to extend transversely with respect to a longitudinal axis of the dressing body, separating a distal portion of the top layer from a proximal portion of the top layer.

9. The medical dressing of claim 1 , wherein the dressing body further comprises a perimeter surrounding a central portion of the dressing body.

10. The medical dressing of claim 9 , wherein the fixed end of the flap is integrally connected to the dressing body at the perimeter of the dressing body.

11. The medical dressing of claim 10 , wherein the medical article includes a catheter system comprising a catheter, and wherein the portion of a medical article includes a proximal portion of the catheter, located proximally with respect to an insertion site covered by a distal portion of the dressing body that is free of the flap.

12. The medical dressing of claim 9 , wherein the fixed end of the flap is integrally connected to the dressing body at a central portion of the dressing body.

13. The medical dressing of claim 9 , wherein the dressing body further comprises a recess from the perimeter into the central portion of the dressing body.

14. The medical dressing of claim 13 , wherein the free end of the flap overlaps at least a portion of the recess in the dressing body.

15. The medical dressing of claim 14 , wherein the recess is configured to allow a portion of the medical article to extend from the second major surface of the dressing body to the first major surface of the dressing body, and wherein the flap is positioned to secure the portion of a medical article to the first major surface of the dressing body, adjacent the recess in the dressing body.
