Description

Die Forderung, jede Injektionskanüle nach Gebrauch durchzuspülen, um Reste des Injektionsmittels aus dem Kanüleninnern zu entfernen, konnte bisher bei Verwendung einer handelsüblichen Zylinderampullenspritze nicht erfüllt werden. Da eine solche Spritze keine geschlossene Wandung hat, kann mit ihr keine Flüssigkeit aufgesaugt werden. Dies ist auch dann nicht möglich, wenn in sie eine Zylinderampulle eingelegt ist, da der beim Gebrauch in das Innere der Ampulle gedrückte Gummikolben nicht mehr zurückgezogen werden kann. The requirement to flush every injection cannula after use, in order to remove residues of the injection agent from the inside of the cannula, it was previously possible cannot be met when using a commercially available cylinder ampoule syringe. Since such a syringe does not have a closed wall, no liquid can be used with it be absorbed. This is not possible even if it has a cylinder ampoule in it inserted because the rubber plunger pressed into the interior of the ampoule during use can no longer be withdrawn.

Der Gegenstand vorliegender Erfindung gibt die Möglichkeit, Inj ektionskanülen von Zylinderampullenspritzen durchzuspülen; hierzu ist ein Zylinder von den Abmessungen einer in das Spritzengestell passenden Zylinderampulle vorgesehen, der an einem Ende einen innerhalb des Zylinders verschiebbaren Kolben hat, am anderen Ende fest durch einen zu durchbohrenden Deckelstopfen verschlossen ist und zwischen Kolben und Deckelstopfen eine Druckvorrichtung (Druckfeder) aufweist. Ferner können erfindungsgemäß Plättchen an beiden Enden der Druckfeder angebracht sein, von denen das am Deckelstopfen anliegende in der Mitte eine Öffnung hat. In den Zeichnungen ist eine Spülampulle gemäß der Erfindung beispielsweise dargestellt, und zwar in Fig. I für sich allein und in Fig. 2 eingefügt in eine Zylinderampullenspritze. The subject matter of the present invention provides the possibility of injection cannulas flush with cartridge syringes; this is a cylinder of the dimensions a cylinder ampoule that fits into the syringe rack and is attached to a End has a piston displaceable within the cylinder, at the other end fixed is closed by a cover plug to be pierced and between the piston and cover plug has a pressure device (compression spring). Furthermore, according to the invention Small plates should be attached to both ends of the compression spring, of which the one on the cover plug adjacent has an opening in the middle. In the drawings is a flushing vial according to the invention shown for example, in Fig. I by itself and in Fig. 2 inserted into a cylinder ampoule syringe.

In der Spülampulle I befindet sich zwischen dem Kolben 2 und dem Deckelstopfen 3 eine Druckvorrichtung, z. B. eine Druckfeder 6. Drückt man vermittels des Stempels 7 der Zylinderampullenspritze 8 den Kolben der Spülampulle in diese hinein, so wird die Druckvorrichtung, z. B. die Feder, gespannt. Hört der Stempeldruck auf, so drückt die Druckvorrichtung den Kolben der Ampulle wieder heraus. Taucht man die Kanülenspitze g in Flüssigkeit, so wird, nachdem beim Hineindrücken des Ampullenkolbens die Luft aus der Ampulle herausgedrückt wurde, bei dem durch den Druck der Druckvorrichtung (Feder) verursachten Heraustreten des Kolbens die Flüssigkeit durch die Kanüle hindurch in die Ampulle hineingesaugt. Beim erneuten Hineindrücken des Kolbens wird die Flüssigkeit wieder herausgedrückt. Dieser Vorgang wird so lange wiederholt, bis die Kanüle gereinigt ist. In the rinsing ampoule I is located between the piston 2 and the Cover plug 3 a pressure device, for. B. a compression spring 6. If you press by means of of the plunger 7 of the cylinder ampoule syringe 8, insert the plunger of the rinsing ampoule into it into it, the printing device, e.g. B. the spring, stretched. Heard the stamp pressure up, the pressure device pushes the plunger of the ampoule out again. Dives if the tip of the cannula is immersed in liquid, after pressing the Ampoule piston, the air was forced out of the ampoule, in which by the Pressure of the pressure device (spring) caused the piston to pop out the liquid sucked through the cannula into the ampoule. When pushing in again the piston pushes the liquid out again. This process will take so long repeatedly until the cannula is cleaned.

Damit sich in der Spülampulle der Druck der Druckvorrichtung, z. B. der Feder, gleichmäßig auf Kolben und Deckelstopfen verteilt und eine Beschädigung dieser Teile durch die Enden der Druckvorrichtung vermieden wird, werden zweckmäßig zwischen Kolben und Deckelstopfen einerseits und Druckvorrichtung andererseits Plättchen aus festem Material eingelegt, 4, 5. Das Plättchen, das beim Deckelstopfen eingefügt wird, 5, muß in der Mitte eine Öffnung haben, damit die Injektionskanüle mit ihrem hinteren Ende in das Innere der Spülampulle gelangen kann. So that the pressure of the pressure device, z. B. the spring, evenly distributed on the piston and cover plug and damage these parts avoided by the ends of the printing device become expedient between the piston and cover plug on the one hand and pressure device on the other hand platelets made of solid material, 4, 5. The plate that is inserted at the lid plug is, 5, must have an opening in the middle so that the injection cannula with its rear end can get into the interior of the rinsing ampoule.

Die Spülampulle kann viele Male verwendet werden. The flushing vial can be used many times.
