Date Jun. 10, 1993A pen-shaped syringe comprises a first part containing a dose setting and driving mechanism from which a piston rod is advanced by a carrier to actuate a piston of a reservoir in a second part. The first and second parts are coupled together by a bayonet coupling, wherein the bayonet coupling element of the second part has members for rotating a piston rod guide mounted on the bayonet coupling element of the first part. The piston rod determines the rotational position of the piston rod which rotational position again determines the engagement between the carrier and the piston rod.</p> |
