Medical connector having locking engagement

摘要

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.

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 carrier member, a biasing member, a needle cannula, and a cam member, the biasing member engaging and biasing the carrier member towards the distal end of the first connector, 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, the carrier member having at least one sealing member; and a second connector having an outer surface, a proximal end, and a distal end, the outer surface of the second connector comprising at least one groove for receiving the at least one projection, 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 first connector is locked to the second connector with the at least one projection engaged with that at least one groove and the needle cannula extending through the at least one sealing member 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 first connector is released from the second connector with the at least one projection released from engagement with the at least one groove.
