The device further comprises user operated actuation means actuatable from a loading state to an intermediate state, and from the intermediate state to an operational state, wherein the cartridge holder is actuated from a receiving state to a holding state when the actuation means is actuated from the loading state to the intermediate state, and the coupling is actuated from a free resetting state to a locked operational state when the actuation means is actuated from the intermediate state to the operational state.

Abstract: A drug delivery device adapted to receive a cartridge and comprising a housing, an expelling assembly with a threaded piston rod, a threaded nut and a drive element arranged in non-rotational engagement with the piston rod, a drive coupling actuatable between a resetting state in which the piston rod can be moved proximally, and an operational state in which the drive element can drive the piston rod distally, wherein the drive element and the threaded nut are not moved axially relative to the housing when the drive coupling is actuated.

Abstract: Drug delivery device adapted to receive a cartridge and comprising a housing, a front-loaded cartridge holder adapted to receive and hold a cartridge in a loaded position, and stop means adapted to engage a proximal surface of a received cartridge The stop means is actuatable between a receiving state in which the stop means is positioned in a first axial position thereby defining how far proximally a received cartridge can be inserted, and an operational state in which the stop means allows an inserted cartridge to be moved axially to a second more proximal position.

Abstract: A drug delivery device has a cartridge holder adapted to receive and hold a cartridge, the cartridge holder having a receiving and a holding state. The device further comprises a drive assembly with a piston rod and a drive spring, setting means allowing a user to set a dose amount to be expelled and strain the drive spring correspondingly, and user actuated release means for releasing the drive spring, wherein the drive assembly spring cannot be released to move the piston rod unless the cartridge holder is in the holding state.

Abstract: A drug delivery device adapted to receive a cartridge and hold it in a mounted position is provided, comprising a housing, an expelling assembly, and a front-loaded cartridge holder assembly adapted to receive and hold a cartridge in a mounted state. The assembly comprises cartridge holding means actuatable between a receiving state and a holding state, as well as a user operated actuation sleeve being rotationally actuatable relative to the housing between a loading state and an operational state, such that the cartridge holding means is actuated from the receiving state to the holding state when the actuation sleeve is actuated from the loading state to the operational state. The actuation sleeve is configured to enclose at least a portion of a mounted cartridge and is provided with inspection means allowing at least a portion of an enclosed cartridge portion to be visually inspected.

Abstract: Drug delivery device comprising a cartridge holder adapted to receive and hold a cartridge in a loaded position, the cartridge holder comprising a distal opening adapted to receive the cartridge. The drug delivery device further comprises an expelling assembly adapted to engage and axially displace a piston in a loaded cartridge to thereby expel a dose of drug from the cartridge, and snap locking means acting on a cartridge being inserted in the cartridge holder, the snap locking means having a locked state in which the cartridge is held in the loaded position and an un-locked state in which the cartridge can be removed from the cartridge holder.

Abstract: Drug delivery system comprising a cartridge with an axially displaceable piston, and a front-loaded cartridge holder adapted to axially receive and hold a cartridge in a loaded position. The cartridge comprises first coupling means arranged at the distal portion, and the cartridge holder comprises second coupling means arranged at the distal portion, wherein the first and second coupling means are configured to engage each other to thereby axially secure a cartridge mounted in the cartridge holder.

Abstract: A drug injector (1) comprising expelling means for expelling a dose of drug from a reservoir, a release member (13) for releasing the drug expelling means, and an actuation member (33) adapted to be moved by a user between an initial, intermediate and actuated position in which the release member is moved to release the drug expelling means. The injector further comprises an electronic capturing system for capturing data representing a dose of drug to be expelled, and a switch (38) for starting initialization of the data capture system, the switch being actuated when the actuation member is positioned in its intermediate position. A spring (34) provides a biasing force against movement of the actuation member between its initial and intermediate position. Thereby the electronic data capturing system is allowed to initialize during the actuation member's movement between the intermediate and the actuated position.

Abstract: An injection device (1) for injecting predetermined doses of liquid drug is disclosed. The injection device (1) comprises a dose setting mechanism and an injection mechanism. A torsion spring (12) is connected to the dose setting mechanism and to the injection mechanism in such a manner that energy is stored in the torsion spring (12) during dose setting, and the energy is released during injection, the stored energy being used for causing the set dose to be injected. A first mode defining element (8) and a second mode defining element (9) are angularly movable relative to each other in response to operation of the dose setting mechanism. They are also axially movable relative to each other between a first position in which the dose setting mechanism can be operated to set a dose and a second position in which the injection mechanism can be operated to inject a set dose.
