Description

Gegenstand des Hauptpatentes 1 242796 ist eine Zweikammerspritze mit einem Kolben, der im Ampullenzylinder zwei Räume für die getrennte Aufnahme zweier flüssiger Medikamente bzw. eines trockenen Medikamentes und eines Lösungsmittels abteilt und mittels einer Kolbenstange verschiebbar ist, wobei der Kolben in an sich bekannter Weise nur zum Ausspritzende hin durchlässig und auf eine nach außen führende Kolbenstange unverschiebbar aufgesetzt ist und wobei sich die Kolbenstange am rückwärtigen Ende des Ampullenzylinders in einem diesen dicht abschließenden Stopfen führt, der so ausgebildet oder angeordnet ist, daß der Vorwärtshub des Kolbens nicht behindert wird. The subject of the main patent 1 242796 is a two-chamber syringe with a piston that has two spaces in the ampoule cylinder for separate admission two liquid drugs or a dry drug and a solvent and is displaceable by means of a piston rod, the piston in on is known to be permeable only towards the end of the ejection and to the outside leading piston rod is attached immovably and wherein the piston rod at the rear end of the ampoule cylinder in a tightly closing one Leads plug which is formed or arranged so that the forward stroke of the piston is not hindered.

Es ist die Aufgabe der Erfindung, eine solche Spritze einfach und billig herzustellen, die lange lagerfähig und betriebssicher ist und sich vor allem genauso betätigen läßt wie die heute gebräuchlichen Einkammerspritzen. Ferner soll sich die Spritze schnell und sicher mit dem Medikament bzw. Lösungsmittel füllen lassen. Zur Lösung dieser Aufgabe wird die Zweikammerspritze nach dem Hauptpatent so weitergebildet, daß erfindungsgemäß die Kolbenstange einen der Länge nach durchgehenden und dicht hinter dem Kolben endenden Einfüllkanal aufweist, der mit dem vom Kolben und Stopfen begrenzten Ampulleninnenraum über mindestens zwei im axialen Abstand voneinander angeordnete Radialbohrungen verbunden und nach dem Einfüllen des Medikamentes oder des Lösungsmittels nach außen hin durch einen Verschlußstopfen verschlossen ist. It is the object of the invention to make such a syringe simple and cheap to produce, which can be stored for a long time and is operationally reliable, and above all can be operated in the same way as the single-chamber syringes in use today. Furthermore should fill the syringe quickly and safely with the drug or solvent permit. The two-chamber syringe according to the main patent is used to solve this problem so developed that according to the invention the piston rod is one lengthwise continuous and has a fill channel terminating just behind the piston, the same with that of the piston and stopper delimited ampoule interior over at least two axially spaced apart connected to each other arranged radial bores and after filling the drug or the solvent is closed to the outside by a stopper is.

Der Erfindungsgedanke läßt die verschiedensten Ausführungsmöglichkeiten zu, eine davon ist in der Zeichnung wiedergegeben, und zwar zeigt Fig. 1 einen Längsschnitt durch die Spritze im Augenblick der Füllung, F i g. 2 einen ähnlichen Schnitt wie F i g. 1 durch die gefüllte Spritze im Lagerzustand. The idea of the invention allows the most diverse implementation possibilities to, one of which is shown in the drawing, namely Fig. 1 shows a longitudinal section through the syringe at the moment of filling, FIG. 2 shows a similar section as F i g. 1 by the filled syringe in storage condition.

Die Spritze besteht im wesentlichen aus dem Ampullenzylinderl, der am vorderen Ende einen mit Gewinde versehenen Hals 2 aufweist und in seinem Innern durch den auf der Kolbenstange 16 sitzenden Kolben 17 in zwei Kammern 19 und 20 unterteilt wird, von denen die eine, nämlich 19, beispielsweise ein pulverförmiges Medikament und die andere, nämlich 20, ein flüssiges Lösungsmittel aufnimmt. Im Hals 2 befindet sich ein elastischer Verschlußstopfen 3, der von der an beiden Enden spitzen Ampulle 5 durchstochen wird, wenn die Schraubkappe 4 völlig auf ihren Sitz aufgedreht wird. Die Nadel 5 wird durch die den Nadelschutz bildende Schraubkappe 7 steril umschlossen. Diese Kappe 7 bildet zugleich eine Zweikammerspritze Zusatz zum Patent: 1 242796 Kolbenverlängerung, wenn sie mit ihrem Gewindeansatz 8 auf das mit Gewinde versehene Ende 22 der Kolbenstange aufgeschraubt wird. The syringe consists essentially of the ampoule cylinder, the has a threaded neck 2 at the front end and inside it by the piston 17 seated on the piston rod 16 in two chambers 19 and 20 is divided, of which one, namely 19, for example a powder Drug and the other, namely 20, absorbs a liquid solvent. in the Neck 2 is an elastic plug 3, which is from the at both ends pointed ampoule 5 is pierced when the screw cap 4 is completely on its seat is turned up. The needle 5 is through the screw cap forming the needle guard 7 sterile enclosed. This cap 7 also forms a Two-chamber syringe add-on for patent: 1 242796 piston extension, if it is with its thread extension 8 on the threaded end 22 of the piston rod is screwed on.

Die Kolbenstange führt sich in dem Verschlußstopfen 21. Am rückwärtigen Ende ist der Ampullenzylinder 1 durch die Platte 13 abgeschlossen, welche eine Bohrung zum Hindurchführen der Kolbenstange aufweist. The piston rod is guided in the sealing plug 21. At the rear At the end of the ampoule cylinder 1 is closed by the plate 13, which has a bore for passing through the piston rod.

Die Kolbenstange 16 hat eine Längsbohrung22, die nach außen hin zunächst offen ist und bis dicht an den Kolben 17 heranreicht. Von der Längsbohrung gehen unmittelbar vor dem Kolben 17 Radialbohrungen 24 und vor dem Stopfen 21 weitere Radialbohrungen 23 aus. In die Längsbohrung 22 der Kolbenstange 16 läßt sich ein dünnes Füllrohr25, beispielsweise in Form einer Hohlnadel, einführen. The piston rod 16 has a longitudinal bore 22, which initially extends outwards is open and reaches close to the piston 17. Go from the longitudinal hole immediately in front of the piston 17 radial bores 24 and in front of the plug 21 more Radial bores 23 from. In the longitudinal bore 22 of the piston rod 16 can be a Insert a thin filling tube25, for example in the form of a hollow needle.
