Abstract
An ostomy appliance has a base plate and a convex element. The base plate includes a film and an adhesive disposed on a proximal surface of the film, with the convex element attached to a distal surface of the film. A first hole is formed in the base plate and a second hole is formed in the convex element and co-axially aligned with the first hole. The second hole defines an inner perimeter edge that provides a lubricating edge that changes from a solid state to a semi-liquid state when exposed to moisture.
