Device for setting a stopper in a syringe cylinder

摘要

The device has a cylinder sleeve (3) i.e. flow channel, guided into a lumen of a syringe cylinder (1) in an axial direction. The sleeve supports a stopper (2) in the interior of the sleeve. Another cylinder sleeve (5) is axially displaced against the former cylinder sleeve and is arranged coaxial to the former sleeve. The latter sleeve comprises a conical centering surface (6) e.g. outer cone surface and sealing surface, at an end turned towards the cylinder. A free end of the latter sleeve projects over an end of the former sleeve in an initial position.
