    Abstract: A system for preventing delivery of less than a predetermined minimum dose of a medicament by providing a dose setting mechanism having a clutch ring rotationally fixed relative to the housing when a dose less than the minimum allowable dose is selected. The dose setting mechanism also includes a drug delivery device housing and a dose dial component positioned in the housing and rotatable during a dose setting step. A drive sleeve is positioned within the dose dial component, a spindle is positioned within the drive sleeve, and a clutch is positioned between the dose dial component and the drive sleeve. When the dose dial component is rotated to select a dose less than a minimum dose, a clutch ring prevents the drive sleeve from rotating to thereby prevent the selected dose from being administered.

    Abstract: A method and system for proving a drug delivery device having a variable dose. The drug delivery device comprising a first tubular member and a second tubular member rotatably coupled to the first tubular member. A maximum stop component is operatively coupled to the first and second tubular member such that the maximum stop component is movable from a first position to a second position. The first position defines a first maximum dose that may be set by a user of said drug delivery device and the second position defines a second maximum dose that may be set by the user of said drug delivery device.

    Abstract: A medicament delivery device (1) comprises a housing (2) for holding a medicament cartridge (9), a drive (18, 32) and a drive control means (46, 52). The medicament cartridge (9) has a medicament outlet and a bung (20) able to be driven via a piston rod (12, 14) driven by the drive force of the drive (18, 32) and controlled by the drive control means (46, 52). Additionally, the medicament delivery device (1) comprises a restraining means (38) for applying a restraining force to the piston rod (12, 14), in a direction opposite to the drive force. By varying the restraining force by the drive control means (46, 52) the movement of the bung (20) along the medicament cartridge can be controlled.
