Abstract: The present invention relates to an injection device for automatic torsion spring driven injection of a liquid drug. The injection device is of the type wherein a telescopically movable needle shield (20) activates the release of the torque of the torsion spring to drive the injection when the needle shield is moved from its extended position to a retracted position. The injection device is provided with a needle interface (30) carrying the injection needle, which needle interface is provided with means (32) preventing axial movement of the shield when no injection needle is mounted. Further, other means are provided to restrain the needle shield in the retracted position when the injection device is its “zero” position such that a user has access to the injection needle in order to exchange the injection needle.

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.

Abstract: The present invention relates to a medical injection system comprising a medical injection device (100) of the type comprising a rotatable dose setting member (160). The system further comprises a dose limiter module (200) adapted for being releasably coupled to the injection device (100). The dose limiter module (200) comprises a dose limiter base (201) and a limiter (240) arranged relative to the dose limiter base (201) so that their relative position is adjustable to set an adjusted dose limiting position. When the dose limiter module (200) is coupled to the injection device (100), the limiter (240) cooperates with the dose setting member (160) to define a blocking means for preventing rotation of the dose setting member (160) beyond the adjusted dose limiting position.

Abstract: The present invention relates to a medical delivery comprising a) a housing (101) adapted to accommodate a drug in a drug reservoir (110), the housing (101) having an exterior surface defining at least one non-circular section, b) a drive mechanism for expelling doses of drug from the drug reservoir (110) and c) an operable control member (150) arranged at the non-circular section of the housing, the operable control member (150) being movable relative to the non-circular section of the housing for altering a parameter relating to the operation of the medical delivery device. The operable control member (150) comprises a belt-like structure arranged to move along the non-circular section of the housing so that respective portions of the operable control member change radius of curvature as the respective portions move relative to the non-circular section of the housing.

Abstract: The present invention relates to an injection device for administering doses of liquid drug. The injection device comprises a user operable dose adjustment structure configured to adjust, in a prepared state of the device, a dose of liquid drug of a first size to set a dose of a second size. The present injection device is particularly suitable for self-injection of liquid drugs such as insulin for treating diabetes by the user or patient.
