Claims22
An ostomy wafer comprising:
- an external layer having an opening to permit the passage of effluent therethrough and a first adhesive to adhere to external skin around a stoma of an ostomate;
- a convex layer coupled to the external layer that includes a stoma channel sized to at least partially receive the stoma, at least one groove radially spaced from the stoma channel that extends at least partially through the convex layer to facilitate deformation of the convex layer complementary to a shape of the stoma, and a second adhesive to further adhere to the ostomate,
- wherein the external layer includes a three layer tri-laminate adhesive structure.
