A plurality of tabs, arranged, e.g., symetrically, on the limbs of the locking ring can be withdrawn generally radially outwardly by movement of the locking ring to permit separation of the two coupling members. The movement of the locking ring which causes withdrawal of the tabs may be a vertically upward movement of the ring, or a vertically downward movement. The movement of the locking ring which causes withdrawal of the tabs alternatively may be a deformation of the ring in opposed horizontal directions. Preferably, however, the movement of the locking ring which causes a withdrawal of the tabs is a rotational movement relative to the second coupling member.

Abstract: An adhesive faceplate for detachable connection to an ostomy pouch is disclosed. The faceplate has an integrated convex pressure ring for promoting stomal protrusion and a so-called floating flange (i.e., coupling ring) for mechanical attachment to the mating coupling ring of an ostomy pouch. The convex pressure ring is provided with a deep annular recess behind the faceplate's coupling ring to accommodate a user's fingers during a coupling operation, thereby facilitating attachment of a pouch. The recess is also useful because it may accommodate the flexible web (which is preferably pleated to allow greater movement of the faceplate's coupling ring) when the coupling ring is immediately adjacent the remainder of the faceplate.

Abstract: The low profile ostomy system includes an adhesively securable repositionable pouch that bonds to a body-side mounting wafer. The repositionable pouch is removable from the mounting wafer for repositioning if necessary. In a preferred embodiment of the invention, a resealable tape, which is in the form of a foam tape, is located on a face plate of the pouch and a releasable film, which is backed by a foam tape, is located on a body-side mounting wafer. The face plate of the pouch is formed with an extension tab that is accessible before and after the pouch has been secured to the body-side mounting wafer. The extension tab facilitates peeling of the face plate from the body-side mounting wafer during removal of the pouch from the mounting wafer. The foam tape on the body-side mounting wafer and the face plate inhibit formation of wrinkles or kinks at the engagement surfaces of the face plate and body-side mounting wafer when the pouch is removed from the body-side mounting wafer.

Thus when the pouch is deposited in a toilet bottom end first in a carrier sleeve, the pouch can flow in streamlined fashion through the passages of a toilet and any sewer pipe or septic line connected to the toilet. Depending upon the flush capacity of the toilet and the flow rate of water through the toilet and sewer line, the ostomy pouch can be deposited in the toilet without a carrier sleeve.
