Abstract: A needle magazine (1, 100) attachable to an injection device containing a liquid drug and which magazine (1, 100) comprises a main part (10, 110) and revolving part (20, 120) which can be rotated to bring a selected needle cannula (35, 135) into an injection position. The magazine (1, 100) is provided with a centrally located tube (13, 113) for penetrating into the injection device and has an internal conduit (14, 114, 115) for guiding the liquid drug from the tube (13, 113) and to a peripheral area of the magazine (1, 100). In this peripheral area a plurality of needle cannulae (35, 135) are provided which needle cannulae (35, 135) successively can be brought into liquid communication with the liquid drug in the conduit (14, 114, 115) by axial movement of the revolving part (20, 120).

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.
