Abstract: The present invention relates to an injection device (1) for setting and injecting set doses from a held drug cartridge (10). The injection device (1) comprises a housing (110,120,130, 140), a piston rod (800), a rotatable driver (500, 700) and a dose setting device (400). The dose setting device (400) comprises a predetermined stop to limit the amount of an expelled dose corresponding to the amount of a set dose. A secondary stop limiter includes first (700) and second (270) components and a secondary stop track follower (950) arranged between the first (700) and second (270) components. If the predetermined stop fails to stop the driver (500, 700) at the end of injection, the secondary stop track follower (950) moves towards a safety stop (708) to prevent the driver (500, 700) from rotating further.

Abstract: The present invention relates to an injection device (1) for setting and injecting set doses from a held drug cartridge (10). The injection device (1) comprises a housing (110, 120, 130, 140), a piston rod (800), a rotatable driver (500, 700) and a dose control member (350). A stored energy source (560) is configured to drive rotation of the driver (500, 700) to cause the piston rod (800) to expel a set dose. The dose control member (350) rotates during dose setting and during dose expelling. A first clutch (C1) is arranged between the dose control member (350) and the driver (500, 700). A second clutch (C2) is arranged between the driver (500, 700) and the housing (110, 120, 130, 140) to control the expelling movement. During dose setting the first clutch (C1) is disengaged and the second clutch (C2) is engaged. During dose expelling the first clutch (C1) is engaged and the second clutch (C2) is disengaged.
