An ostomy appliance that comprises a convex ring insert member. The insert member can have a curved body-side surface, an opposing pouch-side surface defining an internal cavity and an annular curved body portion between an outside flange and an engagement portion encircling a centrally-located input opening. The engagement portion can comprise a plurality of spaced-apart flexible tabs. The internal cavity can be defined by interior surfaces of the flexible tabs and the curved body portion. The flexible tabs can have flexibility to bend toward the internal cavity. A backfill material can be applied into the internal cavity along the interior surfaces of at least some of the flexible tabs. The backfill material can be removable from the ring insert. Upon application of the backfill material, the flexibility of some of the flexible tabs can be reduced to provide a localized rigid support segment along the engagement portion.

A convex shell for use in a base plate of an ostomy appliance includes an annular ring with a through-going hole and a plurality of grooves extending transversely across the annular ring. The grooves alter the flexibility of the annular ring as a first portion of the annular ring is folded around a folding axis toward a second portion of the annular ring.

Certain embodiments of the present application relate to an adjustable ostomy wafer system including an ostomy wafer and an insert ring. The ostomy wafer includes an adjustable layer with an effluent opening through which effluent flows, and the adjustable layer has a body-facing side and a non-body-facing side. The insert ring is capable of providing or increasing convexity of the adjustable layer when the insert ring is pressed against the non-body-facing side of the adjustable layer.

An ostomy barrier appliance for attaching an ostomy appliance to peristomal skin surrounding a stoma is provided. The ostomy barrier appliance includes a skin barrier, an inlet opening for receiving a stoma, and a convexity adjusting device arranged adjacent the skin barrier. The convexity adjusting device is configured to adjust the convexity of the skin barrier.

An adaptable ostomy base plate having a substantially convex shape for initial engagement with a peristomal skin surface and can be inverted to a substantially concave shape to fittingly engage to a topography of the peristomal skin surface for permanent engagement thereto. The base plate comprises a reinforcement ring arranged on a distal surface of the top film and the inner section of the base plate, being inside the reinforcement ring is provided with undulations defined by a series of concentric ridges and valleys, said series progresses outwardly from the stoma-receiving through-going hole towards the reinforcement ring and at least partly under the reinforcement ring.

A base plate of an ostomy appliance includes a film, an adhesive disposed on a proximal surface of the film, an annular ring connected to the distal surface of the film, and a release liner removably attached to the adhesive. A stoma-receiving through-going hole is formed through the film and the adhesive and the release liner. A first section of the base plate extends radially from the stoma-receiving through-going hole to a second section of the base plate, and the second section extends radially from the first section to an outermost perimeter edge of the base plate. The base plate is formed to have a heat-set curvature such that a proximal side of the second section is convex and a distal side of the second section is concave relative to the annular ring.

A locking ring (1) for an ostomy coupling as well as an ostomy coupling is provided. The locking ring includes two extension arms (4,5) connected at a common fulcrum (6) that will act as a hinge, when the arms are rotated with respect to each other. A toggle-mechanism may be used in the locking ring. The extension arms will through a connection to the locking ring close the locking ring upon rotation.

A convex ostomy barrier for attaching an ostomy appliance to a peristomal skin surrounding a stoma includes a skin barrier formed from a skin friendly adhesive, an inlet opening for receiving a stoma, and a convex insert system arranged adjacent the skin barrier to provide a convex body-side contour of the convex ostomy barrier. The convex insert system includes a convex insert and a ring, which are configured to be assembled together to form the convex insert system.
