Abstract

A connector system for a medical device includes a first connector having an elongate opening, and a second connector including a lock portion, where the first connector is movable relative to the second connector between an initial position where the first connector is not in fluid communication with the second connector and an activated position where the first connector is in fluid communication with the second connector. The system also includes a locking member connected to the first connector. The locking member is transitionable between an unlocked position where the second connector is movable within the elongate opening of the first connector and a locked position where the locking member is configured to engage the lock portion of the second connector to lock the first connector to the second connector in the activated position. The locking member comprises a spring body received by the elongate opening of the first connector.

First claim

What is claimed is:

1. A connector system for a medical device comprising:
a first connector having an elongate opening;
a second connector comprising a housing including a lock portion configured to be received within the elongate opening of the first connector, the first connector movable relative to the second connector between an initial position where the first connector is not in fluid communication with the second connector and an activated position where the first connector is in fluid communication with the second connector, the lock portion of the second connector comprising an undercut defined by a recessed portion of the housing; and
a locking member connected to the first connector, the locking member transitionable between an unlocked position where the second connector is movable within the elongate opening of the first connector and a locked position where the locking member is configured to engage the lock portion of the second connector to lock the first connector to the second connector in the activated position, wherein the locking member comprises a spring body received by the elongate opening of the first connector, and wherein the locking member is configured to engage the undercut to lock the first connector to the second connector when the first and second connectors are in the activated position and the locking member is in the locked position, and further wherein the locking member comprises at least one rib extending radially outward from the spring body,
wherein the lock portion comprises a tapered lead-in surface to automatically move the locking member from the locked position to the unlocked position when the first and second connectors are transitioned from the initial position to the activated position, and
wherein the locking member comprises ramps extending radially inward from the spring body, the ramps configured to automatically move the locking member from the locked position to the unlocked position when the first and second connectors are transitioned from the initial position to the activated position.

2. The system of claim 1 , wherein the spring body is deformable between a rested state when the locking member is in the locked position and a biased state when the locking member is in the unlocked position, the spring body configured to return to the rested state.

3. The system of claim 2 , wherein the spring body at least partially blocks the elongate opening of the first connector when the spring body is in the rested state, and wherein the spring body is open to receive the second connector when the spring body is in the biased state.

4. The system of claim 3 , wherein the spring body is oval-shaped in the rested state and circular in the biased state.

5. The system of claim 2 , wherein the locking member further comprises first and second buttons secured to the spring body, and wherein moving the first and second buttons radially inward transitions the spring body from the rested state to the biased state and moves the locking member to the unlocked position.

6. The system of claim 5 , wherein the spring body is annular and the first and second buttons are positioned on opposite sides of the spring body from each other.

7. The system of claim 6 , wherein the first button is connected to the spring body by a first connecting arm and the second button is connected to the spring body by a second connecting arm.

8. The system of claim 5 , wherein the first and second buttons are positioned outside of the elongate opening of the first connector.

9. A system for closed transfer of fluids comprising:
a syringe adapter having a cannula, a proximal end, a distal end, and a wall defining an elongate opening between the proximal end and the distal end;
a vial access device including a lock portion;
a translating housing having a first seal membrane, the translating housing movable within the elongate opening of the syringe adapter, the translating housing transitionable between an initial position in which the syringe adapter is not in fluid communication with the vial access device and an activated position in which the syringe adapter is in fluid communication with the vial access device via the cannula; and
a locking member engaged with the syringe adapter, the locking member transitionable between an unlocked position where the lock portion of the vial access device is movable within the elongate opening of the syringe adapter and a locked position where the locking member is configured to engage the lock portion of the vial access device to lock the syringe adapter to the vial access device in the activated position, wherein the locking member comprises a spring body received by the elongate opening of the syringe adapter, the spring body being deformable between a rested state when the locking member is in the locked position and a biased state when the locking member is in the unlocked position, the spring body is configured to return to the rested state, wherein the spring body at least partially blocks the elongate opening of the syringe adapter when the spring body is in the rested state and is open to receive the vial access device when the spring body is in the biased state, and wherein the spring body defines an oval cross-sectional shape in the rested state and a circular cross-sectional shape in the biased state, and further wherein the locking member comprises at least one rib extending radially outward from the spring body,
wherein the lock portion comprises a tapered lead-in surface to automatically move the locking member from the locked position to the unlocked position when the syringe adapter and the vial access device are transitioned from the initial position to the activated position, and
wherein the locking member comprises ramps extending radially inward from the spring body, the ramps configured to automatically move the locking member from the locked position to the unlocked position when the syringe adapter and the vial access device are transitioned from the initial position to the activated position.

10. The system of claim 9 , wherein with the translating housing in the activated position, the cannula pierces the first seal membrane of the translating housing.

11. The system of claim 9 , wherein the vial access device includes a second seal membrane and with the translating housing in the activated position, the cannula pierces the first seal membrane of the translating housing and the second seal membrane of the vial access device.

12. The system of claim 9 , wherein the vial access device is attachable to a vial defining a vial chamber such that the vial chamber is in fluid communication with the vial access device.

13. The system of claim 12 , wherein with the vial access device attached to the vial and the translating housing in the activated position, the syringe adapter is in fluid communication with the vial chamber via the cannula.

14. The system of claim 9 , wherein the syringe adapter defines a viewing window and with the translating housing in the initial position, a first indicator is displayed in the viewing window.

15. The system of claim 14 , wherein with the translating housing in the activated position, a second indicator is displayed in the viewing window, the second indicator different than the first indicator.
