Abstract

The present disclosure provides a coupling assembly ( 12 ) for an ostomy appliance ( 10 ) comprising a clamp arrangement ( 60 ), a first coupling and a second coupling. The clamp arrangement ( 60 ) comprises a clamp ring ( 61 ) mounted to the first and/or second coupling and a clamp locked mounted to the clamp ring ( 61 ). The clamp ring ( 61 ) comprises an inner circumference ( 62 ) adjustable between clamped and unclamped configurations. In the clamped configuration the clamp ring ( 61 ) is for maintaining the first and second couplings ( 20, 40 ) in a coupled configuration. The clamp lock ( 80 ) is adjustable into a locked configuration to lock the clamp ring ( 61 ) in the clamped configuration. The clamp lock ( 80 ) comprises a clamp actuator ( 81 ) moveable radially relative to the inner circumference ( 62 ) to unlock the clamp lock ( 80 ) from the locked configuration.

First claim

The invention claimed is:

1. A coupling assembly for an ostomy appliance, the coupling assembly comprising:
a clamp arrangement, a first coupling and a second coupling, wherein the clamp arrangement comprises:
a clamp ring, mounted to the first and/or second coupling, comprising an inner circumference adjustable between clamped and unclamped configurations, wherein in the clamped configuration the clamp ring is for maintaining the first and second couplings in a coupled configuration, and wherein the clamp ring comprises a continuous member defining an annulus; and
a clamp lock mounted to the clamp ring and adjustable into a locked configuration to lock the clamp ring in the clamped configuration, wherein the clamp lock comprises a clamp actuator moveable radially relative to the inner circumference to unlock the clamp lock from the locked configuration, wherein the clamp actuator is moveable radially to unlock the clamp lock and the clamp lock comprises a latch, wherein the latch comprises a lever engageable with a catch, the clamp actuator being configured to disengage the lever from the catch when moved radially relative to the inner circumference to unlock the clamp lock from the locked configuration.

2. A coupling assembly as claimed in claim 1 wherein the clamp lock is mounted to and extends radially outwardly from the clamp ring.

3. A coupling assembly as claimed in claim 1 , wherein the clamp lock comprises a snap-fit mechanism.

4. A coupling assembly as claimed in claim 1 , wherein the clamp actuator is mounted to the lever.

5. A coupling assembly as claimed in claim 4 wherein the catch comprises a hoop and the lever comprises a hook configured to engage with the hoop in the locked configuration.

6. A coupling assembly as claimed in claim 4 , wherein the lever is resiliently biased to engage the catch when the clamp ring is in the clamped configuration.

7. A coupling assembly as claimed in claim 1 , further comprising first and second tabs mounted to and extending radially outwardly from the clamp ring.

8. A coupling assembly as claimed in claim 7 wherein the first and second tabs comprise the clamp lock.

9. A coupling assembly as claimed in claim 8 , wherein the lever extends from the first tab and the second tab comprises the catch.

10. A coupling assembly as claimed in claim 7 wherein the first and second tabs are positioned about the clamp ring to be moveable towards one another to reduce the inner circumference and adjust the clamp ring from the unclamped configuration to the clamped configuration.

11. A coupling assembly as claimed in claim 1 , wherein:
the inner circumference of the clamp ring is greater in the unclamped configuration than in the clamped configuration; and/or
wherein the clamp ring is springy and resiliently biased to return from the clamped configuration to the unclamped configuration; and/or
wherein the clamp ring comprises first and second clamp ring ends moveable relative to one another between the clamped and unclamped configurations; and/or
wherein the second coupling is configured to be mounted within the first coupling in the clamped configuration; and/or
wherein the second coupling is press-fitted to the first coupling in the clamped configuration.

12. A coupling assembly of claim 1 , comprising an ostomy appliance comprising a pouch and a wafer, wherein the first coupling is attached to the pouch and the second coupling is attached to the wafer or vice-versa such that the wafer and pouch can be disconnected by uncoupling the first and second couplings.

13. The coupling assembly of claim 1 , wherein the clamp ring is split.

14. The coupling assembly of claim 1 , wherein the clamp lock is configured to transition from the locked state to the unlocked state in response to radially-inward movement of the lever.

15. A coupling assembly for an ostomy appliance, the coupling assembly comprising:
an inner coupling;
an outer coupling mounted about the inner coupling; and
a clamp arrangement comprising:
a clamp ring mounted about the outer coupling, wherein the clamp ring comprises a continuous member defining an annulus; and
a clamp lock having a locked state in which the clamp lock retains the clamp ring in a clamped state and retains engagement between the inner coupling and the outer coupling, and an unlocked state in which the clamp ring is in an unclamped state and permits separation of the inner coupling and the outer coupling;
wherein the clamp lock comprises a lever configured to transition the clamp lock between the locked state and the unlocked state as the lever moves radially relative to the outer coupling; and
wherein the clamp ring is rotatable relative to the outer coupling when the clamp ring is in the unclamped state.

16. The coupling assembly of claim 15 , wherein the clamp lock is configured to transition from the locked state to the unlocked state in response to radially-inward movement of the lever.

17. The coupling assembly of claim 15 , wherein the clamp ring is split.
