First Claim
Patent Images
1. An ostomy coupling comprising:
- first and second coupling members capable of being coupled together, each of said members having a central stomal opening, said first coupling member having a flange with a projection-receiving channel, said channel being defined at least in part by a concentric inner wall and outer wall, said inner wall being positioned closer to said stomal opening, said outer wall having a plurality of tab-receiving slots extending therethrough, said second coupling member having a projection receivable in said channel when said first and second members are properly pushed together, said projection being lockable in said channel, anda resilient, circular, releasably lockable locking ring positionable circumferentially about said outer wail, said locking ring including a plurality of tabs projecting radially inwardly, said tabs being extendable through said slots so as to restrain said projection in said channel when said locking ting is in a latched condition, said tabs being withdrawable from said slots when said locking ring is released into an open condition, said locking ring having two ends that are latched to form said locked condition, and unlatched to form said open condition.

Abstract
It would be desirable to have improved designs of ostomy couplings which embody a springy or resilient split ring as a locking ring.
In an ostomy coupling, first and second coupling members 80, 90 are held together by a springy flexible split locking ring 100. A plurality of tabs 101 symmetrically arranged on each limb of the locking ring 100, can be withdrawn generally radially outwardly by movement of the locking ring to permit separation of the two coupling members. The split ring 100 is for the most part circular in its unstressed condition.
