Ostomy coupling
First Claim
1. An ostomy coupling comprising:
- a first and a second annular coupling part; and
a locking ring for locking together the two coupling parts,each of the two coupling parts having an attachment surface for attaching a part associated with the corresponding coupling part,the first coupling part comprising;
a collar having a radially outwardly projecting annular edge, the edge defining a groove with an in radial direction innermost groove section, and an annular recess positioned in the radial direction inner side of the collar,the second coupling part comprising;
an axially projecting part having an annular radially outwardly projecting beak, the beak being structured and arranged on the second coupling part so as to engage the annular recess in the first coupling part when the first coupling part is positioned around the second coupling part, andthe locking ring having an annular in the radial direction inwardly projecting protrusion, and the locking ring is positioned in the groove of the first coupling part,wherein when the locking ring is in a locked position with respect to the first and second coupling parts, an innermost diameter of the locking ring is smaller than a largest diameter of the beak of the second coupling part, andthe annular recess at the inner side of the first coupling part is closer to the attachment surface of the first coupling part than the groove section of the first coupling part.

Abstract
An ostomy coupling including two annular coupling parts and a locking ring. Each coupling part is attached to one of an adhesive disc, or a collection receptacle or a closing plug. The first coupling part has a collar with a radially outwardly projecting annular edge. The edge forms a groove with an in the radial direction innermost groove section. An annular recess is positioned in the radial direction inner side of the collar. The second coupling part has an axially projecting part with an annular radially outwardly projecting beak capable of engaging the annular recess in the first coupling part. The locking ring has an annular protrusion that projects inwardly in the radial direction. The locking ring is positioned in the groove of the first coupling part, so that its innermost diameter when it is in its locked position, is smaller than the largest beak diameter of the second coupling ring, and the annular recess of the first coupling part is closer to the attachment surface of this coupling part to the collection receptacle, the closing plug or the adhesive disc than the annular innermost groove section.

16. An ostomy coupling comprising:
-
a first and a second annular coupling part; and a locking ring for locking together the two coupling parts, each of the two coupling parts having an attachment surface for attaching a part associated with the corresponding coupling part, the first coupling part comprising; a collar having an edge, the edge defining a groove with a groove section at an inner portion of the groove, and an annular recess provided at an inner side of the collar, the second coupling part comprising; a projecting part having an annular beak, the beak being structured and arranged on the second coupling part so as to engage the annular recess in the first coupling part when the first coupling part is positioned around the second coupling part, and the locking ring having a protrusion, wherein when the locking ring is in a locked position with respect to the first and second coupling parts, an innermost diameter of the locking ring is smaller than a largest diameter of the beak of the second coupling part, and the annular recess of the first coupling part is closer to the attachment surface of the first coupling part than the groove section of the first coupling part. - View Dependent Claims (17, 18)
