Description

Spritze. Bei vorliegender Erfindung handelt es sich um eine Vorrichtung zur Bremsung und Fixierung des, langen zylindrischen Voll-oder Hohlkolbens von Injektionsspritzen. Bekannt ist schon, daß zur Bremsung des Kolbens ein -Metallring um den Glaszylinder der Spritze gestreift wird. Dem gegenüber besteht das Neue darin, daß die Bremsung bewirkt wird durch ein aus dem geschlitzten und darum federnden Metallring nach innen hervorragendes Schräubchen, das durch ein Loch des Spritzenzylinders hindurchgreifend mit seinen kugeligen Ende auf dem Kolben aufsitzt.Syringe. The present invention is a device For braking and fixing the long, cylindrical solid or hollow plunger of injection syringes. It is already known that a metal ring around the glass cylinder is used to brake the piston the syringe is touched. On the other hand, the novelty consists in the braking is effected by a metal ring that is slit out of the and therefore resilient Inside protruding screw that reaches through a hole in the syringe barrel sits with its spherical end on the piston.

Die Zeichnung zeigt eine Ausführungsform.The drawing shows an embodiment.

Um den Kolben K jederzeit in einer beliebigen Stellung festzuhalten und um ihn beim K achuntenhalten der Spritze vor einem ungewollten Herausfallen zu, schützen, ist, wie gesagt, über den Spritzenzvlinder G ein an einer Stelle aufgeschlitzter !Metallring F geschoben, der mit einem Schraubloch zur Aufnahme einer kleinen Madenschraube S versehen ist. Das Schräul;chen ist etwas mehr als doppelt so lang wie die Zylinderwandstärke und in seineirr vorderen Ende kugelig abgerundet. Es greift durch ein am Zylinder eingebohrtes Loch hindurch und wird durch die Federkraft des passenil gewählten Ringmaterials auf den Kolben K zur Bremsung aufgedrückt. Beim Zurückziehen des Kolbens schnappt das Schräubchen in eine in den Kolben gezogene Einschnürunl; oder geschliffene Rille 1Z ein und verhindert hierdurch ein zu weites Zurückziehen oder Herausfallen des Kolbens. Infolge des kugeligen Schraubenendes und der in einer sanften Welle verlaufenden Einschnürungsschnittlinie kann aber der Kolben trotzdem auf Wunsch mittels kräftigeren Zuges ;ederzeit auch ganz aus vier Spritzt= li@rausgezogen werden.To hold the piston K in any position at any time and to prevent the syringe from accidentally falling out when holding the syringe down in the kitchen to protect, is, as I said, a slit at one point over the syringe cylinder G ! Metal ring F pushed, the one with a screw hole to accept a small grub screw S is provided. The little square is a little more than twice as long as the cylinder wall thickness and rounded in its front end in a spherical manner. It engages through a cylinder drilled hole through it and is chosen by the spring force of the passtil Ring material pressed onto the piston K for braking. When the piston is withdrawn the screw snaps into a constriction drawn into the piston; or ground Groove 1Z and thereby prevents it from being pulled back too far or falling out of the piston. As a result of the spherical screw end and that in a gentle wave However, the piston can still use the constriction cutting line on request by means of a stronger pull; at any time, can also be pulled out completely from four syringes = li @.
