Abstract

An adapter for connection with a fluid container includes an outer housing having a distal end, a proximal end, and a generally cylindrical sidewall extending between the distal end and the proximal end, an inner member comprising a body rotatably inserted within the outer housing, a first locking arrangement configured to restrict the inner member from rotating relative to the housing in a first direction, and a second locking arrangement configured to restrict the inner member from rotating relative to the housing in both the first direction and a second direction. The adapter is transitionable between: a disengaged state, in which the first locking arrangement and the second locking arrangement are not engaged with the inner member; a partially engaged state in which the first locking arrangement engages the inner member; and a fully engaged state in which the second locking arrangement engages the inner member.

First claim

The invention claimed is:

1. An adapter for connection with a fluid container comprising:
an outer housing having a distal end, a proximal end, and a generally cylindrical sidewall extending between the distal end and the proximal end;
an inner member comprising a body rotatably inserted within the outer housing and a connector extending from the body configured to connect the adapter to a fluid container;
a first locking arrangement engageable with the body of the inner member and configured to restrict the inner member from rotating relative to the housing in a first direction; and
a second locking arrangement engageable with the body of the inner member and configured to restrict the inner member from rotating relative to the housing in both the first direction and a second direction,
wherein the adapter is transitionable between: a disengaged state, in which the first locking arrangement and the second locking arrangement are not engaged with the inner member; a partially engaged state in which the first locking arrangement engages the inner member; and a fully engaged state in which the second locking arrangement engages the inner member.

2. The adapter according to claim 1 , wherein the inner member is rotatable in both the first direction and the second direction when the connector is in the disengaged state.

3. The adapter according to claim 1 , wherein the inner member is transitionable from an extended position to a recessed position by applying a compressive force to the inner member.

4. The adapter according to claim 3 , further comprising a biasing member that maintains the inner member in the extended position.

5. The adapter according to claim 4 , wherein the biasing member is a leaf spring.

6. The adapter according to claim 3 , wherein the first locking arrangement comprises at least one protrusion extending inward from an inner surface of the sidewall of the housing and a corresponding protrusion on the body of the inner member configured to engage the protrusion on the sidewall.

7. The adapter according to claim 6 , wherein the at least one protrusion extending inward from an inner surface of the sidewall of the housing and the corresponding protrusion on the body of the inner member are one-way ratchets comprising a sloped face and a substantially vertical face.

8. The adapter according to claim 1 , wherein the first locking arrangement comprises at least two protrusions positioned on opposing circumferential sides of the sidewall of the housing and at least two corresponding protrusions extending from the body of the inner member.

9. The adapter according to claim 1 , wherein the second locking arrangement comprises at least one inwardly extending tab connected to a portion of the sidewall of the housing and configured to selectively engage a portion of the inner member.

10. The adapter according to claim 9 , wherein the at least one tab comprises a pressing surface configured such that applying a compressive force to the pressing surface biases the tab inward to engage the portion of the inner member.

11. The adapter according to claim 10 , wherein the tab is connected to the sidewall of the housing at a flexible joint, such that application of the compressive force to the pressing surface biases the tab inward about the flexible joint.

12. The adapter according to claim 10 , wherein the second locking arrangement further comprises a beam that connects the tab to the sidewall of the housing, and wherein applying a compressive force to the pressing surface deflects the beam inward thereby extending the at least one tab toward the inner member.

13. The adapter according to claim 12 , wherein the second locking arrangement comprises two beams connected to opposing sides of the tab.

14. The adapter according to claim 9 , wherein the second locking arrangement further comprises at least one tooth extending radially from the inner member, the tooth being configured to engage the at least one tab.

15. The adapter according to claim 1 , wherein the second locking arrangement comprises at least two inwardly extending tabs positioned on opposing sides of the sidewall of the housing.

16. The adapter according to claim 1 , wherein the connector comprises an outer surface with helical threads, configured to engage corresponding threads on an inner surface of a portion of the fluid container.

17. The adapter according to claim 16 , wherein the connector comprises a luer connector configured to receive a corresponding luer connector of the fluid container.

18. The adapter according to claim 1 , wherein the inner member is transitionable from an extended position to a recessed position relative to the outer member, wherein the inner member is in the disengaged state when in the extended position, and wherein the inner member is in one of the partially engaged state and the fully engaged state when in the recessed position.

19. The adapter according to claim 18 , wherein the inner member is in the fully engaged state when the inner member is in the recessed position and when the second locking arrangement is engaged with the body of the inner member.

20. A method of disconnecting a fluid container to an adapter comprising:
providing an adapter comprising:
an outer housing having a distal end, a proximal end, and a generally cylindrical sidewall extending between the distal end and the proximal end;
an inner member comprising a body rotatably inserted within the housing and a connector extending from the body comprising a connector configured to engage with the fluid container;
a first locking arrangement engageable with the body of the inner member and configured to restrict the inner member from rotating relative to the housing in a first direction; and
a second locking arrangement engageable with the body of the inner member and configured to restrict the inner member from rotating relative to the housing in both the first direction and a second direction;

moving the fluid container in an axial direction towards the adapter;
engaging the second locking arrangement; and
rotating the fluid container to disconnect the fluid container from the inner member of the adapter.
