Description
Zylinderampulle mit Injektionsnadel Zusatz zum Patent 890 564 Die Erfindung bezieht sich auf eine Zylinderampulle mit Injektionsnadel nach Patent 890 564, bei welcher die Injektionsnadel, durch die die Injektionsflüssigkeit mittels eines als Kolben dienenden Verschlußstopfens ausgetrieben wird, an ihrem unteren Ende mit einem flanschartigen Ansatz ausgestattet ist, der auf der mit einem Rollrand versehenen Ampullenöffnung mittels einer umbördelbaren Kappe befestigt ist. Die Nadel ist durch ein Glasröhrchen geschützt, welches über eine auf dem olivenförmig bzw. geriffelten Teil des Nadelansatzes gezogene Gummimanschette aufge setzt ist.Cylinder ampoule with injection needle Addition to patent 890 564 Die The invention relates to a cylinder ampoule with an injection needle according to the patent 890 564, in which the injection needle, through which the injection liquid by means of a stopper serving as a piston is driven out at its lower one The end is equipped with a flange-like attachment, which on the one with a rolled edge provided ampoule opening is attached by means of a crimped cap. the The needle is protected by a glass tube, which is over an olive-shaped or the corrugated part of the needle hub pulled rubber sleeve is placed.
Eine solche Zylinderampulle muß in ein Spritzbesteck eingespannt werden, welches durch Federdruck die Ampulle in der richtigen Lage festhält. Der Sterilverschluß der Nadel kann von unbefugter Seite durch Abnehmen des Röhrchens und Wiederaufsetzen desselben verletzt werden, ohne daß die Verletzung nachgewiesen werden kann. Such a cylinder ampoule must be clamped in a syringe which holds the ampoule in the correct position by spring pressure. Of the Sterile closure of the needle can be done by unauthorized parties by removing the tube and resumption of the same can be injured without the injury being detected can be.
Es wurde nun gefunden, daß dieser Nachteil behoben ist, wenn erfindungsgemäß zusammen mit der Injektionsnadel eine als Verschluß für die Nadel dienende Hülle aus elastischem Material an ihrem flanschartigen Ende mittels einer Bördelkappe befestigt wird. Auf diese Weise wird ein Originalverschluß der Nadel erreicht. Beim Abziehen der Hülle wird der flanschartige Rand der Hülle, durch die Dehnung dünner geworden, aus der Bördelkappe herausgezogen und ist in seine ursprüngliche Lage nicht wieder einzubringen, so daß ein unbefugtes Öffnen und die dadurch hervorgerufene Unsterilität sofort erkennbar ist. It has now been found that this disadvantage is eliminated when according to the invention together with the injection needle, a sheath serving as a closure for the needle made of elastic material at its flange-like end by means of a crimp cap is attached. In this way an original closure of the needle is achieved. At the Pulling off the cover, the flange-like edge of the cover becomes thinner as a result of the stretching has been pulled out of the crimp cap and is in its original position not to be reintroduced, so that unauthorized opening and the resulting Unsterility is immediately recognizable.
Die Bördelkappe ist zweckmäßig mit einem Außengewinde versehen, auf das ein Spritzbehälter und ein hohlzylindrischer Stößel mit Flansch aufschraubbar sind, wobei der beispielsweise aus Kunststoff bestehende Spritzbehälter die Zylinderampulle aufnimmt und der Stößel die Nadelhülle als Schutz umgibt. Der als Schutz für die Nadel dienende Stößel wird zum Gebrauch des Gerätes von der Bördelkappe abgeschraubt und mit seinem flanschlosen, mit einer Gewindebohrung versehenen Ende auf den Gewindenippel des Kolbens geschraubt und dient somit gleichzeitig auch als Kolbenstange. The crimp cap is expediently provided with an external thread a spray container and a hollow cylindrical plunger with flange can be screwed on are, where the spray container, for example made of plastic, is the cylinder ampoule picks up and the plunger surrounds the needle cover as protection. As protection for them The needle serving plunger is unscrewed from the crimp cap to use the device and with its flangeless end provided with a threaded hole on the threaded nipple of the piston and thus also serves as a piston rod.
Um zu vermeiden, daß Injektionsflüssigkeit in die Nadel kommt und somit durch Verdunstung eine Pfropfenbedienung in der Nadel entsteht, wird die Nadel mit einem Mandrin versehen, der an der Nadelspitze umgebogen ist. Beim Abziehen der Nadelverschlußhülle wird der Mandrin gleichzeitig mit herausgezogen, da die umgebogene Spitze des Mandrins sich am inneren Wulst der Hülse festhakt. To prevent the injection liquid from getting into the needle and thus creating a plug operation in the needle through evaporation, the needle becomes provided with a stylet which is bent over at the tip of the needle. When peeling off the needle lock cover, the stylet is pulled out at the same time as the bent tip of the stylet hooks onto the inner bead of the sleeve.
