Description
Es sind Impfspritzen bekannt, bei denen die Kolbenbewegung über Förderklinken
in Verbindung mit einer gezahnten Kolbenstange druchgeführt werden, und wobei die
Rückführbewegung dieser Kolbenstange durch besondere Steuermittel erfolgt, die die
Förderklinke jeweils ausser Eingriff mit der Zahnstange bringen, um diese dann von
Hand in jede neue Anfangsstellung zurückführen
zu kennen. Hierfür
sind besondere Lagerstellen und Zwischenglieder innerhalb des Bewegungsablaufes
der Vorder-
Um den jeweiligen Kolbenweg festzulegen, entsprechend
Um zu verhindern, dass der Kolben bei der Rtickführbewegung aus dem
Gehäuse und damit auch ausserhalb des Klinkeneingriffes für die neue Anfangsstellung
herausläuft, ist dieser als Wegbegrenzung mit einer umlaufenden Ringnut versehen,
in die dann
die Förderklinke bei der Bückbewegung zwangläufig einrastet
ohne
Die Lagerung des Drehpunktes des Abzugshebels 3 in Verbindung mit
der davor in Griffnähe liegenden Druckfeder 4 ergibt eine ruhige Lage beim Betrieb
ohne störende Nickbewegungen des Gehäuses l. Die Feder 4 selbst ist dabei ohne Behinderung
des Abzugsbügels in besonderen Ausnehmungen des Gehäuses 1 und jeder des Abzugbügels
3 eingelassen. Auf diese @eise legt sich der Abzugsbügel 3 in der Abzugsstellung
unmittelbar gegen eine Fläche des Gehäuses 1. ohne von der Feder 4 behindert zu
werden. Durch den Drehpunkt und diese Gehäusefläche ist damit der Hubweg genau festlegbar.
Die
Kolbenstange 8 ist in dem Gehäuse 1 in Umfangsrichtung
Eine selbsttätige Sperrvorrichtung 14, beispielsweise in Form eines Winkelhebels mit entsprechender Eigenfederung sorgt dafür, dass der Vorschub der Zahnstange genau festgelegt ist. Die Sperrvorrichtung greift dabei in die Verzahnung 7 ein. In dem Aus rungsbeispiel ist die Sperrvorrichtung als Winkelhebel ausgeführt, wobei das freie Ende mit einer Öffnung 15 die Zahnstange umfasst, sodass die untere öffnungskante 16 in die Verzahnung 7 einrastet. An automatic locking device 14, for example in the form of a Angle lever with its own suspension ensures that the advance of the Rack is precisely defined. The locking device engages in the toothing 7 a. In the exemplary embodiment, the locking device is designed as an angle lever, wherein the free end with an opening 15 includes the rack, so that the lower opening edge 16 engages in toothing 7.
Auch diese Sperrvorrichtung 14 wird bei Verdrehung der Kolbenstange 8 über die Griffteile 12 ausser Tätigkeit gesetzt.This locking device 14 is also activated when the piston rod is rotated 8 set on the handle parts 12 out of action.
Die Auswechslung der Ampulle lo kann über einen nicht näher Dargestellten
Schlitz in dem Hülsenteil 17 erfolgen. welches auf
das Gehäuse 1
aufschraubbar ist. Weiterhin besteht die Möglichkeit, die Ampulle 10 in ein Hülsenteil
einzulegen, und dieses mit
