Abstract

A medical dressing (100) with a dressing body (102) and a flap (104). The flap can include a fixed end (120) coupled to the dressing body, and a free end (122) movable with respect to the dressing body between a first position and a second position in which the free end is positioned in overlapping relationship with the dressing body. A second major surface (116) of at least the free end of the flap can be configured to be secured to the dressing body, and the flap can be located toward a proximal end of the dressing body, such that a distal portion of the dressing body is free of the flap. The dressing body can be adhered to skin with a skin-contact adhesive (e.g., a silicone adhesive) (115), and the flap can be secured to the dressing body with a securing adhesive (e.g. an acrylate adhesive) (117) that can have a higher adhesion or adhesive strength.

Claims

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; and

a flap comprising

a first major surface,

a second major surface, opposite the first major surface,

a fixed end coupled to the dressing body, and

a free end movable with respect to the dressing body between a first position in which the free end is not positioned in an overlapping relationship with the dressing body and a second position in which the free end is positioned in overlapping relationship with the dressing body,

wherein the second major surface of at least the free end of the flap is configured to be secured to the dressing body, wherein the flap is located toward a proximal end of the dressing body, such that a distal portion of the dressing body is free of the flap, wherein the second major surface of at least the free end of the flap is configured to be secured to the dressing body by a securing adhesive, and 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.

2. The medical dressing of claim 1, wherein the fixed end of the flap is secured to the first major surface of the dressing body with the securing adhesive.

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

4. The medical dressing of claim 1, wherein the dressing body further comprises:

a perimeter surrounding a central portion of the dressing body, and

a recess extending from the perimeter into a central portion of the dressing body.

5. The medical dressing of claim 4, wherein the free end of the flap overlaps at least a portion of the recess in the dressing body when the free end of the flap is in the second position.

6. The medical dressing of claim 4, 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 the medical article to the first major surface of the dressing body, adjacent the recess in the dressing body.

7. The medical dressing of claim 6, wherein the medical article includes a catheter system comprising a catheter, and wherein the portion of the medical article includes a proximal portion of the catheter, located proximally with respect to an insertion site.

8. The medical dressing of claim 7, wherein the insertion site is covered by a distal portion of the dressing body that is free of the flap.

9. The medical dressing of claim 1, wherein the dressing body includes a transparent window, and wherein the flap is located proximally with respect to the transparent window.

10. The medical dressing of claim 1, wherein the second major surface of at least the free end of the flap comprises the securing adhesive.

11. The medical dressing of claim 1, wherein the securing adhesive is provided by at least one adhesive landing pad on the first major surface of the dressing body.

12. The medical dressing of claim 1, wherein the fixed end of the flap is coupled to the dressing body at a location that is proximal with respect to a transparent window of the dressing body, and wherein the free end of the flap moves proximally from the first position to the second position.
