Abstract
The current invention relates to a base plate (1) for an ostomy collection device, the base plate comprises at least one backing layer (3) whereon an outer adhesive layer (4) is disposed on the proximal side of said backing layer, wherein the outer adhesive layer encircles an inner adhesive layer (7) also disposed on the proximal side of at least one backing layer, said inner adhesive layer encircles a through-going hole (5) of the base plate defining a central axis A-A, wherein at least a part of the backing layer whereon the inner adhesive layer is disposed is extendable in a radial direction in respect to the central axis A-A. By allowing the backing layer to be radially extendable with the inner adhesive layer, the backing layer functions as a barrier to output from the stoma. Thus, output from the stoma will not come in direct contact with the distal side of the inner adhesive layer, which is shielded by the backing layer and thus extends the wear time of the ostomy appliance and reduces the risk that leakage may occur.
