Abstract: A mechanical injection device for injecting apportioned doses of a liquid drug. The injection device comprises a dose setting assembly comprising a cap and a cap receiving part, adapted to abut or engage with the cap when the cap is mounted on the injection device, and an injection assembly. Mounting and/or dismounting of the cap on/from the injection device causes the dose setting assembly to set a dose. Thereby a correct dose of drug is automatically set during a cap on/cap off cycle. Since such a cycle is normally performed between two subsequent injections, the number of steps required to be performed by the user is reduced.

The forcing of liquid into the vial provides a pressure therein, which can be used for infusion of the reconstituted drug directly from the vial. The device also comprises a suction unit (13) for aspiration.

Abstract: A refillable injection device (1) having a dose setting mechanism with a dose setting member (4) and a dose rod (11). The dose setting member and the dose rod engage during normal operation of the injection device, and they do not engage during change of cartridge. The dose setting member and the dose rod need to be moved into engagement when a new cartridge is inserted in the injection device. Thereby there is a risk that stress is build-up in the piston rod. In order to prevent this, the cartridge holder is operatively connected to the dose rod in such a manner that when a cartridge is being inserted in the cartridge holder, the dose rod is caused to move along with the piston rod in an axial direction, at least while the dose setting member and the dose rod are moved into engagement.

Abstract: A drug delivery device capable of working in at least two different modes which includes a dose injection mode and a set-up mode. The drug delivery device automatically changes from the dose injection mode to the set-up mode and vice versa in accordance with the detection of the cover by a cover detection switch. In the dose injection mode doses can be set and injected; in the set-up mode various parameters assisting the use of the drug delivery device can be set. This setting is preferably done by selecting the parameters from a menu, also in this mode historical data stored in the device can be viewed.

Abstract: A cartridge having a distal end provided with a mechanical coding. The coding has the form of a circular protrusion where the circular outer diameter is dedicated a specific concentration of insulin contained in the cartridge. The distal end of the cartridge is fitted in to a circular contour in the housing. The outer diameter of the protrusion on the distal end of the cartridge is chosen as a larger diameter for a higher concentration of insulin. In this way only a cartridge containing the correct concentration or a lower concentration fits into a delivery system designed for a specific concentration of insulin.
