Convex barrier ring
First Claim
Patent Images
1. A barrier ring adapted for attaching an ostomy appliance to a peristomal skin surrounding a stoma, the barrier ring comprising:
- a cat-eye shaped body defining a major axis and a minor axis and having elongated peripheral end portions that taper along the major axis of the cat-eye shaped body;
a convex proximal bodyside surface;
a flat bottom surface; and
a stoma-receiving apertures;
wherein the elongated peripheral end portions include ridges that are configured to fit in skin folds or creases to improve a seal between the barrier ring and the peristomal skin.

Abstract
A convex barrier ring, that includes a generally oval shaped body and tapered peripheral end portions, is provided. In use, the convex barrier ring is sealed against peristomal skin surfaces such that the tapered peripheral end portions are aligned with folds or creases in the skin surfaces to reduce leakage of stomal effluent. The convex barrier can also have an oval stoma-receiving aperture to provide an improved fit for oval or loop stomas.

15. A barrier ring adapted for attaching an ostomy appliance to a peristomal skin surrounding a stoma, comprising:
-
a cat-eye shaped body defining a major axis and a minor axis and having elongated peripheral end portions that taper alone the major axis of the cat-eye shaped body; a bodyside surface; a bottom surface; a stoma-receiving aperture; and wherein the bodyside surface, when viewed in a cross-section taken along the major axis defines a convex surface transitioning to a concave surface from the stoma-receiving aperture to a respective elongated peripheral end portion, wherein the elongated peripheral end portions include ridges that are configured to fit in skin folds or creases to improve a seal between the barrier ring and the peristomal skin. - View Dependent Claims (16)

17. A method adapted for of attaching an ostomy appliance to peristomal folded or creased skin surfaces surrounding a stoma of a wearer, the method comprising:
-
providing a convex barrier ring comprising; a convex proximal bodyside surface; a flat bottom surface; an oval stoma-receiving aperture; and a cat-eye shaped body defining a major axis and a minor axis and having elongated peripheral end portions that taper along the major axis of the cat-eye shaped body, wherein the elongated peripheral end portions include ridges that are configured to fit in skin folds or creases to improve a seal between the convex barrier ring and the peristomal folded or creased skin surfaces; placing the flat bottom surface on an adhesive side of a faceplate of the ostomy appliance; arranging the ostomy appliance assembled with the convex barrier ring around the stoma such that the stoma is arranged in the oval stoma-receiving aperture; sealing the convex proximal bodyside surface against the peristomal folded or creased skin surfaces such that the elongated peripheral end portions are aligned with the skin folds or creases. - View Dependent Claims (18)
