摘要：
The drive mechanism comprises a piston rod, a dose member with a thread engaging a corresponding thread of the body to allow a helical movement of the dose member with respect to the body, a drive sleeve rotationally coupled to the dose member, and stop means provided to restrict or inhibit a movement of the drive sleeve in the proximal direction and in the distal direction with respect to the body, the drive sleeve and the piston rod being unidirectionally coupled.
