DRIVE ASSEMBLY SUITABLE FOR USE IN A DRUG DELIVERY DEVICE AND DRUG DELIVERY DEVICE

摘要

A drive assembly (1) for use in a drug delivery device (50) is proposed, the drive assembly comprising: a housing (2) having a proximal end (3) and a distal end (4); an axis (A) extending between the proximal end and the distal end;
at least one drive member; a piston rod (6) adapted to be driven along the axis by the drive member; an indicator (5) adapted to provide positional information about a position of the piston rod relative to the proximal end, wherein
the indicator and the piston rod are configured to convert a relative movement along the axis of indicator and piston rod with respect to one another into a rotational movement of the indicator. Additionally, a drug delivery device comprising the drive assembly is provided for.
