Abstract

A medical connector system including a first connector and a second connector. The first connector has a housing, a biasing member, and at least one projection. The second connector has at least one groove for receiving the at least one projection. The proximal end of the second connector is configured to be at least partially disposed within the distal end of the housing of the first connector. Upon application and release of a first set of opposing axial forces applied to the connector system, the first connector is locked to the second connector and, upon application and release of a second set of opposing axial forces, the first connector is released from the second connector. The connectors may include indicators to show when the connector system is in the locked position.

First claim

The invention claimed is:

1. A medical connector system comprising:
a first connector having a proximal end and a distal end, the first connector comprising a housing defining a central opening that receives a needle cannula and a cam member, the cam member having at least one projection extending into the central opening of the housing of the first connector with the cam member being rotatable relative to the housing of the first connector; and
a second connector having an outer surface, a proximal end, and a distal end, the outer surface of the second connector defining a groove comprising a substantially vertical receiving channel, a substantially non-vertical locking channel extending substantially perpendicular to the receiving channel, and a substantially vertical exit channel extending substantially perpendicular to the locking channel,
wherein the proximal end of the second connector is configured to be at least partially disposed within a distal end of the housing of the first connector, and
wherein, upon application and release of a first set of opposing axial forces applied to the proximal end of the first connector and the distal end of the second connector, the at least one projection is directed into the receiving channel and then into the locking channel to lock the first connector to the second connector and, upon application and release of a second set of opposing axial forces to the proximal end of the first connector and the distal end of the second connector, the at least one projection is directed out of the locking channel and then out of the exit channel to unlock the first connector from the second connector.

2. The medical connector system according to claim 1 , wherein the second connector includes at least two projections extending from the outer surface to define the groove.

3. The medical connector system according to claim 1 , wherein the locking channel comprises a locking recess configured to receive the at least one projection of the first connector when the first connector and the second connector are locked.

4. The medical connector system according to claim 3 , wherein the locking channel further comprises a substantially vertical wall to direct the at least one projection of the first connector into the locking recess.

5. The medical connector system according to claim 1 , wherein the receiving channel includes a chamfered surface for directing the at least one projection of the first connector into the receiving channel.

6. The medical connector system according to claim 1 , wherein the first connector further comprises a carrier member received in the housing, wherein the carrier member comprises a sealing member in at least one of a distal end of the carrier member and a proximal end of the carrier member.

7. The medical connector system according to claim 1 , wherein the first connector further comprises a cap connected to a proximal end of the housing, the cap comprising an attachment to connect the first connector to a medical device.

8. The medical connector system according to claim 7 , wherein a proximal end of the needle cannula is held in the cap.

9. The medical connector system according to claim 1 , wherein the second connector further comprises an attachment on a distal end thereof for connection to a medical connection member.

10. The medical connector system according to claim 1 , wherein the first connector further comprises a first indicator and the second connector further comprises a second indicator, and wherein, upon application and release of the first set of opposing axial forces applied to the proximal end of the first connector and the distal end of the second connector, the first connector is locked relative to the second connector in an axial direction and the first indicator is aligned with the second indicator.

11. The medical connector system according to claim 10 , wherein the first indicator and the second indicator are axial bands.

12. The medical connector system according to claim 10 , wherein the first indicator is a dot and the second indicator is a circle.

13. The medical connector system according to claim 10 , wherein the first indicator includes a window defined in the cam member and the second indicator is an axial band.

14. The medical connector system according to claim 10 , wherein the first indicator includes a window defined in the cam member and the second indicator is a symbol.

15. The medical connector system according to claim 1 , wherein the housing of the first connector comprises planar gripping portions.

16. The medical connector system according to claim 1 , wherein the housing of the first connector comprises a plurality of annular ribs extending circumferentially around an outer surface of the housing.

17. The medical connector system according to claim 1 , wherein the first connector defines a concave grip portion.

18. The medical connector system according to claim 1 , wherein at least one of the proximal end and the distal end of the first connector is conical shaped.

19. A method of transferring a fluid from a first medical device for receiving or dispensing fluids to a second medical device for receiving or dispensing fluids, the method comprising:
providing a first connector having a proximal end and a distal end, wherein the proximal end is connected to the first medical device and the distal end is open, the first connector comprising a housing and a cam member, wherein the cam member comprises at least one projection extending from an inner surface of the cam member;
providing a needle cannula within the housing of the first connector to transfer the fluid from the first medical device to the second medical device;
providing a second connector having a proximal end and a distal end, wherein the distal end is connected to the second medical device, the second connector comprising a groove defined in an outer surface of the second connector;
inserting the proximal end of the second connector at least partially into the open distal end of the first connector;
applying and releasing a first set of opposing axial forces to the proximal end of the first connector and the distal end of the second connector, wherein the at least one projection of the first connector is directed into and locked in the groove of the second connector;
transferring the fluid from the first medical device to the second medical device through the first connector and the second connector; and
applying and releasing a second set of opposing axial forces to the proximal end of the first connector and the distal end of the second connector, wherein the at least one projection of the first connector is released from and directed out of the groove of the second connector.
