1. A convex ostomy barrier assembly for attaching an ostomy appliance to a peristomal skin surrounding a stoma, the convex ostomy barrier assembly comprising:
a skin barrier comprising an adhesive;
an inlet opening for receiving a stoma;
a convex insert arranged adjacent the skin barrier, the convex insert having a convex ring-shaped body and comprising:
an inner flange;
a middle portion including a pouch-side surface, a core-out portion, and a skin barrier support structure for supporting the skin barrier; and
an outer flange, wherein the inner flange and the outer flange are connected by the middle portion and arranged in different axial planes to define the convex ring-shaped body,
wherein the middle portion comprises a radial wall having the pouch-side surface radially and directly extending from the outer flange toward the inlet opening, and an axial wall extending axially from the radial wall in a body-side direction, wherein the inner flange extends from the axial wall toward the inlet opening, wherein the outer flange, the middle portion, and the inner flange provide a protrusion in the body-side direction, and wherein the pouch-side surface is defined on a pouch-side of the radial wall and located axially between the inner flange and an outer periphery of the outer flange; and
a flange including a body-side coupling ring attached to the pouch-side surface of the convex insert.
 
10. A convex insert for an ostomy barrier having a convex ring-shaped body and comprising:
an inlet opening;
an inner flange;
a middle portion including a pouch-side surface, a core-out portion, and a skin barrier support structure, wherein the core-out portion is configured to improve flexibility of the convex insert; and
an outer flange, wherein the inner flange and the outer flange are connected by the middle portion and arranged in different axial planes to define the convex ring-shaped body,
wherein the middle portion comprises a radial wall having the pouch-side surface radially and directly extending from the outer flange toward the inlet opening, and an axial wall extending axially from the radial wall in a body-side direction, wherein the inner flange extends from the axial wall toward the inlet opening, wherein the outer flange, the middle portion, and the inner flange provide a protrusion in the body-side direction, and wherein the pouch-side surface is defined on a pouch-side of the radial wall and located axially between the inner flange and an outer periphery of the outer flange.
