A drug delivery device comprises a medicament reservoir attached to a housing, a drive mechanism comprising a plunger movable relative to the housing, a dose selecting element releasably coupled to the drive mechanism and rotatable relative to the housing, a trigger axially movable relative to the housing, and a limiter selectively permitting and preventing axial movement of the trigger depending on the amount of a selected dose. The limiter is constrained to the dose selecting element and to the trigger. One of the limiter or a component part is axially coupled to the housing comprises a track which is in engagement with a blocking feature of the other of the limiter or the component part axially coupled to the housing. The track comprises a narrow section limiting relative movement between the track and the blocking feature and a wide section permitting relative movement between the track and the blocking feature.

Drug delivery device

A drive mechanism for an injection device for setting and dispensing of a dose of a medicament includes an inner body fixable inside a housing of the injection device, the inner body including an elongated shaft extending in an axial direction. The elongated shaft includes an outer thread and a blocking structure on an outer circumference. The drive mechanism includes a tubular-shaped display member having an inner thread engaged with the outer thread of the inner body, a dose member axially displaceable between a dose setting position and a dose dispensing position relative to the inner body, and a blocking sleeve axially fixed to the dose member, rotationally fixed to the display member and including at least one blocking element to axially engage with the blocking structure to block an axial displacement of the dose member from the dose setting position towards the dose dispensing position.

Drive mechanism for an injection device

The present disclosure relates to a drive mechanism for an injection device. The mechanism includes an inner body fixable inside a housing of the injection device and including an elongated shaft extending in an axial direction. The shaft includes an outer thread and a blocking structure on an outer circumference. A tubular-shaped display member has an inner thread engaged with the outer thread of the inner body. A dose member is axially displaceable relative to the inner body or the display member between a dose setting position and a dose dispensing position. A blocking ring is axially engageable with the dose member, rotationally fixed to the display member and includes a blocking element to axially engage with the blocking structure for blocking an axial displacement of the dose member from the dose setting position towards the dose dispensing position.
