Abstract

The present invention relates to a coupling assembly such as a coupling assembly for coupling an ostomy bag to a base plate, said base plate being adhered around a stoma. The present invention especially relates to a coupling assembly comprising a first, second and third coupling part, which are coupled together to form a coupling assembly.

Claims

1. A coupling assembly comprising a first, second and third coupling element for coupling a first and second part to each other in an axial direction, wherein

the first coupling element comprises a first engagement area, extending between a first inner radius and a first outer radius,

the second coupling element comprises a second engagement area, extending between a second inner radius and a second outer radius, the second engagement area being radially displaceable between an engagement position, where the second outer radius is larger than the first inner radius, and a disengagement position, where the second outer radius is smaller than the first inner radius,

the third coupling element comprising a locking member and being axially displaceable in relation to the second coupling element between a locking position and an unlocking position, and wherein the second engagement area is secured in its engagement position when the locking member is in its locking position.

2. A coupling assembly according to claim 1, wherein the coupling assembly is a coupling assembly for a two-piece ostomy bag including a body-side coupling part and a bag-side coupling part.

3. A coupling assembly according to claim 1, wherein the third coupling element is a lock ring.

4. A coupling assembly according to claim 1, wherein the body-side coupling part comprises the first coupling element.

5. A coupling assembly according to claim 1, wherein the body-side coupling part comprises the second coupling element.

6. A coupling assembly according to claim 1, wherein the body-side coupling part comprises the third coupling element.

7. A coupling assembly according to claim 1, where the third coupling element is a plastic part.

8. A coupling assembly according to claim 7, where the third coupling element is a plastic part with at least two components.

9. A coupling assembly according to claim 1, wherein the first coupling element is provided with additional sealing means.

10. A coupling assembly according to claim 1, wherein the second coupling element is provided with additional sealing means.

11. A coupling assembly according to claim 9, wherein the sealing means is a sealing lip.

12. A coupling assembly according to claim 9, wherein the sealing means is a sealing rib.

13. A coupling assembly according to claim 1, wherein the first coupling element on a proximal surface is provided with a U-shaped groove seen in cross-section.

14. A coupling assembly according to claim 1, wherein the second coupling element and the third coupling element are provided with first and second guiding means respectively, the first and second guiding means being in the form of a thread.
