A dispense interface for use with a drug delivery device. The dispense interface comprises a main outer body and an inner body. The inner body may be configured for connection to a drug delivery device and defines a first reservoir and a second reservoir. A first piercing needle is in fluid communication with the first reservoir and positioned for piercing a first cartridge of a drug delivery device. A second piercing needle is provided and in fluid communication with the second reservoir and positioned for piercing a second cartridge contained with a drug delivery device. A manifold is positioned adjacent the inner body and comprises a fluid groove arrangement. A valve arrangement is positioned between the inner body and the manifold and controls fluid communication of a first fluid contained in the first cartridge and a second fluid contained in the second cartridge by way of the fluid groove arrangement to a holding chamber. The dispense interface may further comprise a lockout preventing dispense interface reuse.

Dispense interface for use with a drug delivery device for delivery of two or more drug agents

The invention faces the technical problem of providing a tight connection between a tube and an dispense interface, while at the same time the biocompatibility of the connection can be improved. The technical problem is solved by an apparatus comprising a tube configured to guide a medium and a dispense interface. The tube comprises a first opening and a second opening, while the dispense interface comprises a recess. The recess has a first opening and a second opening and the tube is at least in part inserted into the recess. The tube is permanently affixed to the dispense interface by a combination of an interference fit and an adhesive, such that the interference fit prevents the adhesive from contaminating the medium.
