Ostomy coupling
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 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 wall, said locking ring including a plurality of tabs projecting radially inwardly through said slots so as to lock said projections in said channel which said coupling members are coupled together, said locking ring including a manually grippable portion, said grippable portion being movable radially outwardly so as to move said locking ring radially outwardly and withdraw said tabs from said slots of said locking ring releasing said projection, said locking resiliently returning to lock said projections in said channel upon release of said grippable portion when said coupling members are coupled together.

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 50, 60 are held together by a springy flexible split locking ring 70. A plurality of tabs 71 symmetrically arranged on each limb of the locking ring 70, can be withdrawn generally radially outwardly by an upward pull on the locking ring to permit separation of the two coupling members. The ring 70 is generally circular in its unstressed condition.
