Abstract An ostomy appliance intended for attachment to a peristomal area of a wearer includes a pad of medical-grade skin-attachable adhesive material, a first coupling element secured thereto, the element having a medically-extending flange attached to a surface of the pad and an upstanding rib of closed loop form constructed to couple with a couterpart (second) coupling element on a bag or pouch. An inner chute member is located radially within and adjacent to the first coupling element, the chute member having a substantially cylindrical wall covering the whole of the radially inner surface of the first coupling element. At one of its ends, the chute has a radially outwardly extending flange positioned so that it traps the chute member in position when the two coupling elements are coupled together.
An ostomy appliance intended for attachment to a peristomal area of a wearer including a pad of medical -grade skin-attachable adhesive material, a first coupling element secured thereto, the element having an extending flange attached to a surface of the pad and an upstanding rib of closed loop form constructed to couple with a counterpart second coupling element on a bag or pouch having a stomal orifice, said second coupling element comprising inner and outer parallel spaced apart upstanding walls which form a channel surrounding the stomal orifice to accept the upstanding rib of the first coupling element and a separate inner chute member located radially within and adjacent to the first coupling element, the chute member having a substantially cylindrical wall covering the whole of the radially inner surface of the first coupling element and, at one of its ends, a radially outwardly extending flange positioned to be engaged under the end of the inner wall of said second coupling element said chute member is trapped when the two coupling elements are coupled together.
