Abstract
An orifice coupling, e.g. an ostomy coupling, includes a first coupling part (10) securable to a second coupling part (20) by a springy split locking ring (30). The locking ring (30) is held captive on the first coupling member (10) by lugs (13) extending radially from outside the locking ring and which enable the locking ring (30) to engage the second coupling member (20) substantially continuously around the periphery of the second coupling member. The coupling can be released when the ends (26,27) of the locking ring (30) are manipulated to expand the ring. The locking ring (30) may be integrally moulded with the first coupling member, and folded into an operative position on the first coupling member.
Claims15
A coupling for a medical device comprising:
- first and second coupling members adapted for surrounding a body opening;
- a resilient split locking ring integral with and mounted on said first coupling member, said first and second coupling members being releasably securable together by said locking ring, said locking ring engaging said second coupling member substantially continuously around said periphery of said second coupling member so as to secure said coupling members together, said locking ring releasing said second coupling member when external forces are applied to expand said locking ring.
A coupling for a medical device comprising:
- first and second coupling members adapted for surrounding a body opening;
- a resilient split locking ring retained on said first coupling member, said first and second coupling members being releasably securable together by said locking ring,
- said first coupling member including retaining means radially outward of said locking ring for retaining said locking ring thereon, said retaining means permitting expansion of said locking ring when an external force is applied to said locking ring, said locking ring being expandable for releasing said second coupling member and permitting said coupling members to be seperated.
