Device for filling a syringe barrel or for inserting a stopper into it

摘要

#CMT# #/CMT# 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. #CMT#USE : #/CMT# Device for setting a stopper in a syringe cylinder of a two-component syringe that injects pharmaceutical substances. #CMT#ADVANTAGE : #/CMT# The free end of the cylinder sleeve projects over the end of the other cylinder sleeve in the initial position, thus ensuring sufficient coaxial adjustment between the syringe cylinder and the cylinder sleeves during retraction of the cylinder sleeve into the syringe, and hence avoiding damages of the syringe cylinder and the cylinder sleeves in a safe manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a device for setting a stopper at a clean cylindrical syringe body. 1 : Syringe cylinder 2 : Stopper 3, 5 : Cylinder sleeves 4 : Support body 6 : Conical centering surface.
