摘要：
The disclosure relates to an injection device for expelling of a number of preset or user-selectable doses of a medicament. The injection device includes an elongated housing extending along an axial direction and configured to accommodate a cartridge containing the medicament and having a bung sealing a proximal end of the cartridge, a windup expelling mechanism, and a dose setting mechanism. The dose setting mechanism includes a handle, a dose tracking member, and a limiter. The dose tracking member is rotatable relative to the housing within a range of positional states and operatively connectable to the handle for tracking a rotation thereof. The limiter is operationally engageable with the dose tracking member and a trigger of the windup expelling mechanism for blocking actuation of the trigger when the dose tracking member is in one of a number of predetermined sections of the range of positional states.
