Ostomy bag coupling
First Claim
1. An ostomy bag coupling including a body side coupling which includes first seal means surrounding an inlet or stoma aperture and body side support means supporting and integrally formed with said first seal means, and a bag side coupling which includes second seal means for cooperating with said first seal means and a bag side support means associated with said second seal means, said bag side support means including, at a plurality of locations spaced therearound, walls extending radially in the plane of the bag side support means, said walls defining respective generally arcuately extending slots, each of which lies in the plane of its respective radially extending wall and is open at one end and closed at the other and has sidewalls defining the sides of the slots, and the body side support means including a plurality of spaced projections for being releasably received in said slots, whereby on engagement of said first and second seal means and subsequent relative rotation of said support means in the appropriate sense, said projections are received in respective slots thereby releasably locking the coupling against separating movement.

Abstract
An ostomy bag coupling appliance has body side and bag side couplings each including a seal means. The bag side coupling includes one ring like member carrying the seal means associated with a locking ring which can be rotated relative to the member. The locking ring and the body side coupling have interengaging parts whereby upon relative rotational movement (about the axis of the coupling) these cooperating parts can be engaged and disengaged so locking together, or allowing to be released, as the case may be, the body side and bag side couplings.

16. An ostomy bag coupling including a body side coupling which includes first seal means surrounding an inlet or stoma aperture and body side support means supporting said first seal means, and a bag side coupling which includes second seal means for cooperating with said first seal means and a bag side support means associated with said second seal means, said bag side support means including, at a plurality of locations spaced therearound, walls extending radially in the plane of the bag side support means, said walls defining respective generally arcuately extending slots, each of which lies in the plane of its respective radially extending wall and is open at one end and closed at the other and has sidewalls defining the sides of the slots, and the body side support means including a plurality of spaced projections for being releasably received in said slots, wherein the sidewalls of each of said slots on said one support means converge axially towards a flange portion of the other support means and each associated projection is generally complementarily shaped to the slot and at least one of said slots and projections include complementary detent members, whereby on engagement of said first and second seal means and subsequent relative rotation of said support means in the appropriate sense, said projections are received is respective slots thereby releasably locking the coupling against separating movement.
- 17. An ostomy bag coupling including a body side coupling which includes first seal means surrounding an inlet or stoma aperture and body side support means supporting said first seal means, and a bag side coupling which includes second seal means for cooperating with said first seal means and a bag side support means associated with said second seal means, said body side and bag side support means being in contact or closely separated when the body side coupling is coupled to the bag side coupling, one of said body side and bag side support means including, at a plurality of locations spaced therearound, walls extending radially in the plane of the body side or bag side support means, as the case may be, said walls defining respective generally arcuately extending slots, each of which lies in the plane of its respective radially extending wall and is open at one end and closed at the other and has sidewalls defining the sides of the slots, and the other support means including a plurality of spaced projections for being releasably received in said slots, whereby on engagement of said first and second seal means and subsequent relative rotation of said support means in the appropriate sense, said projections are received in respective slots thereby releasably locking the coupling against separating movement.
