Abstract: A drive mechanism for a drug delivery device, preferably for a pen-type injector, the mechanism comprises a spindle (6) movable in a first direction during a delivery step, a splined portion (5, 11) operatively coupled to the spindle (6), and retraction means (12, 15, 16, 17, 20) acting on the splined portion (5, 11) at least at the end of the delivery step. Thereby, that after the delivery step the spindle (6) and/or the splined portion (5, 11) is moved in a second direction contrary to the first direction, such that the whole drive mechanism is relieved from stresses.

Abstract: The present invention relates to a drug delivery device for dispensing of a dose of a medicament, comprising a housing to accommodate a cartridge being at least partially filled with a medicament, wherein the housing comprises a dispensing end with an access opening which is closed by a tamper-evident closure.

Abstract: The present invention relates to an arrangement for use in a drug delivery device comprising a cartridge holder, the cartridge holder comprising an opening at its distal end, a needle holder and one or more intermediate elements, wherein when the needle holder is mounted to the cartridge holder and the one or more intermediate elements are arranged in the opening of the cartridge holder whereby the size of the free space within the opening is reduced. Furthermore, it relates to a drug delivery device which is comprising such an arrangement and to a method for stabilizing a septum located at the distal end of a medicament cartridge.

Abstract: A drive mechanism of a drug delivery device is presented having, a piston rod to operably engage with a piston of a cartridge containing a medicament, a first functional component and a second functional component whose position or orientation relative to each other is unambiguously correlated to a predefined axial position of the piston rod, wherein the first and/or the second functional component comprise at least one engaging portion to inseparably and to adhesively engage the first and the second functional component with each other for rendering the drive mechanism inoperable when the predefined axial position of the piston rod has been reached.

Abstract: A drive mechanism of a drug delivery device is presented comprising of a piston rod extending in an axial direction to be operably engaged with a piston of a cartridge, the piston rod being adapted to exert distally directed pressure to the piston for expelling a liquid medicament from the cartridge. A housing component to accommodates the piston rod and has a guiding member extending in a lateral plane and being engaged with piston rod for guiding the same in axial direction relative to the housing component. At least one actuation lock is used to engage with the piston rod to inhibit a proximally directed movement of the piston rod relative to the housing component.

Abstract: A method for securing a cartridge (4) in a cartridge holder (3) is provided, the method comprising the steps of inserting the cartridge (4) into the cartridge holder (3), the cartridge holder (3) having a proximal end and a distal end, axially displacing the cartridge (4) in a proximal direction with respect to the cartridge holder (3) from a distal initial position to a proximal end position and securing the cartridge (4) in the end position against displacement in the distal direction with respect to the cartridge holder (3). An assembly for a drug delivery device (1) is provided comprising a cartridge (4), an adjusting member (12, 25, 28, 34) and a cartridge holder (3). The cartridge holder (3) has a distal end and a proximal end. The adjusting member (12, 25, 28, 34) is secured to the cartridge holder (3).
