Summary: | A drug delivery device (1) comprising a delivery unit (3) including a drug container (6) in the form of a drug cartridge containing a liquid drug (78) therein, a liquid flow system (7), a pumping system (8) and a casing (9) within which the drug container (6), the pumping system (8) and at least a part of the liquid flow system (7) are mounted, the drug container comprising a septum (6c) sealing an end of the drug container, the liquid flow system (7) comprising an injection delivery system (13) including an injection needle (15) configured for injection of the drug in an actuated state of the drug delivery device. The liquid flow system further comprises a container fluidic connection system (17) including a septum needle (18) mounted on a movable septum needle support (19), a spring (23) pressing the septum needle support towards the septum of the drug container, and a blocking organ (24) movable by an actuation mechanism from a blocking position in which the septum needle support (19) is held in a retracted position where the septum needle (18) is not in contact with the septum (6c), to an actuated position in which the septum needle support is released and allowed to travel towards the drug container septum such that the septum needle (18) pierces through the septum (6c) under the force of the spring (23). |
