  Injektionsspritze.



   Vorliegende Erfindung betrifft eine In  jektionsspritze für    Serienimpfungen, bei welchen es auf ein rasehes Einstellen und auf genaue Dosierung ankommt. Bei der Injek  tionsspritze gemäss    der Erfindung ist die eingestellte Dosierung vor und nach der   Injek-    tion ablesbar.



     Beiliegende Zeichnung veranschaulicht    ein Ausführungsbeispiel der Erfindung, und zwar zeigt :
Fig.   1    eine Ansicht,    einen      2 einen Querschnitt nach der    Linie .   I7S,   
Fig. 3   einen Querschnitt nach    der Linie
Fig.4 und 5 einen Ansehlag im Axial  setrnitt    und im Quersehnitt naeh der Linie   E-F    in grösserem Massstab.   



   Die gezeiehnete Injektionsspritze besteht    aus dem Zylinder 1, beispielsweise aus Glas oder Metall, und aus dem Kolben 2, dessen Kolbenstange 3 mit dem versehiebbaren und auf die gewünschte Dosis einstellbaren Ansehlag 4 versehen ist. Die Kolbenstange 3 besitzt Gradeinteilung und Einschnitte 7,   8,    9.



  Der Anschlag enthält eine   Einstellvorriehtung    5, bestehend aus einer Stellsehraube 6 und einer   Sehraubenfeder    5, die einander gegen über angeordnet sind. Mittels der Stellschraube 6 kann der Anschlag in der eingestellten Gradeinteilung festgestellt werden.



  Die Feder 5 wirkt beim Verstellen des Ansehlages als Bremse. In einem im Anschlag   angebrachten Guckloch    8 kann die eingestellte Dosis vor und nach der Injektion auf der Skala abgelesen werden.  



   PATENTANSPRUCH :
Injektionsspritze, dadurch gekennzeichnet, dass die Kolbenstange eine   Gradeinteilung    und einen   versehiebbaren    Anschlag aufweist, welcher eine Stellschraube und eine Schraubenfeder besitzt, das Ganze so, dass die Versehiebung des Ansehlages bei der Verstellung durch die   Sehraubenfeder    gebremst und der Anschlag durch die Schraube festgestellt werden kann, ferner gekennzeichnet durch ein im Anschlag angebraehtes   Guckloch,    durch welches die eingestellte Dosis vor und nach der Injektion ablesbar ist.

  Injection syringe.



   The present invention relates to an injection syringe for serial vaccinations, in which it is a matter of a rasehes setting and precise dosage. In the case of the injection syringe according to the invention, the set dosage can be read off before and after the injection.



     The accompanying drawing illustrates an embodiment of the invention, namely shows:
1 shows a view, and FIG. 2 shows a cross section along the line. I7S,
Fig. 3 is a cross section along the line
4 and 5 show a view in the axial section and in the cross section near the line E-F on a larger scale.



   The injection syringe shown consists of the cylinder 1, for example made of glass or metal, and the piston 2, the piston rod 3 of which is provided with the displaceable stopper 4 that can be adjusted to the desired dose. The piston rod 3 has graduation and notches 7, 8, 9.



  The stop contains an adjustment device 5, consisting of an adjusting screw 6 and a screw spring 5, which are arranged opposite one another. The stop in the set graduation can be determined by means of the adjusting screw 6.



  The spring 5 acts as a brake when adjusting the stop position. In a peephole 8 provided in the stop, the set dose can be read on the scale before and after the injection.



   PATENT CLAIM:
Injection syringe, characterized in that the plunger rod has a graduation and a displaceable stop which has an adjusting screw and a helical spring, the whole thing in such a way that the displacement of the stop position is braked during the adjustment by the very cube spring and the stop can be determined by the screw, further characterized by a peephole made in the stop, through which the set dose can be read before and after the injection.
