MEDICATION DELIVERY DEVICE, USE OF MEDICATION DELIVERY DEVICE AND METHOD OF PRODUCTION OR ASSEMBLAGE OF MEDICATION DELIVERY DEVICE

摘要

The invention refers to a medication delivery device (1) comprising a housing (3) having a proximal and a distal end, a medication receptacle (2) designed to be engaged with the distal end of the housing (3) by engagement of first engagement means (5) with second engagement means (4) and a dosing mechanism. The dosing mechanism includes a piston rod (17) which is moveable in a distal direction for medication delivery and a drive device for moving the piston rod (17) in the distal direction for medication delivery. The medication receptacle (2) comprises an actuation means (70) for bringing and holding a guiding means (11) in a guiding position in which the guiding means (11) guides the piston rod (17) for medication delivery. The first engagement means (5) and the second engagement means (4) are moveable into engagement by a movement of the medication receptacle (2) which ends in a rotational movement without axial movement of the medication receptacle (2) with respect to the housing (3), the actuation means (70) thereby bringing the guiding means (11) in the guiding position.
