Abstract
A wound dressing patch includes a backing film; an absorbent foam pad coupled to a portion of one surface of the backing film; an adhesive sheet provided on a remaining portion of the one surface of the backing film; and a lining material provided along a peripheral edge portion of the adhesive sheet and configured to impart a predetermined stiffness to the backing film. The lining material is spaced apart from the absorbent foam pad to surround the absorbent foam pad in a form of a substantially closed curve along the peripheral edge portion of the adhesive sheet, and a distance between the lining material and an end of the adhesive sheet is shorter than a distance between the lining material and an edge of the absorbent foam pad.

A wound dressing patch, comprising:
- a backing film;
- an absorbent foam pad coupled to a portion of one surface of the backing film;
- an adhesive sheet provided on a remaining portion of the one surface of the backing film, wherein the adhesive sheet is coated with an adhesive agent, and made of a material through which an exudate discharged from a wound passes;
- and
- a lining material provided along a peripheral edge portion of the adhesive sheet and configured to impart a predetermined stiffness to the backing film, wherein the lining material is at least partially embedded within the adhesive sheet without being embedded within the backing film and the absorbent foam pad,
- wherein the lining material is spaced apart from the absorbent foam pad in a radially outward direction to surround the absorbent foam pad in a form having a substantially closed curve along the peripheral edge portion of the adhesive sheet,
- wherein a distance between the lining material and an end of the adhesive sheet is shorter than a distance between the lining material and an edge of the absorbent foam pad, and
- wherein a cross section of the lining material has a circular shape with a diameter equal to or smaller than a thickness of the adhesive sheet.
