The present invention provides a receptacle used in a passive drug delivery system. The receptacle includes first flow path for supplying along a fluid conduit a medical liquid, second flow path for introducing the medical liquid into a container containing a beneficial agent, third flow path for delivering a mixed solution containing the medical liquid and agent, and a guide valve for controlling the flow path by closing or opening the flow path.

Receptacle for passive drug delivery

An adapter for interconnecting in fluid communication a first connection site and a beneficial agent container having a closure. The adapter includes a plate having first and second connection site sides. A wall extends from the plate from the second connection site side and constructed to surround only the closure. This allows containers having varying sized bodies to be received. A cannula structure is rigidly secured in the plate and defines a flow path extending through the plate. The adapter can be provided in an assembly with the beneficial agent contained or in a drug delivery system.

Vial adapter

A drug delivery device is provided comprising a cartridge body including an upper portion defining a vial receiving area and terminating in a wall, the cartridge body including a cannula extending from the wall. A vial including a beneficial agent is coupled by a retaining member to the cartridge body in an inactivated position. The retaining member allows the vial to move to an activated position. The retaining member including an outer member and an inner member, the inner member separating from portions of the outer member as the vial moves from the inactivated position to the activated position.

Drug delivery system

The present invention provides an improved cannula that can be used to reconstitute powdered drugs in a drug delivery system. Furthermore, the present invention provides a cannula and drug delivery system incorporating same. To this end, the present invention provides a cannula structure for use in a reconstitution device for reconstituting a powdered drug comprising a cannula having a first end and a second end, and defining a channel in an interior thereof between the first and second ends. The first end is closed and includes a member for piercing a septum. The cannula includes at least two slots providing fluid communication between the channel and an exterior of the cannula. The slots are located in juxtaposition to the first end and have a width, as measured along a length of the cannula, that is less than a length, as measured around the cannula. The slots also have a minimum projected area equal to or greater than the cross-sectional area of the channel.
