Description

Kanülenhalter für Injektionsspritzen Die bei Injektionsspritzen angewendeten Kanülen sind in der Regel an einem ganz aus Messing hergestellten Ansatz befestigt, in dessen konischer Bohrung der Spritzenkonus Halt findet und abgedichtet wird, indem er sich gegen die innere Wandung klemmt. Damit ein sicherer Halt und eine gute Abdichtung erzielt werden, muß beim Aufstecken des Kanülenhalters auf den Spritzenkonus ein kräftiger Druck mit einer gleichzeitig drehenden Bewegung ausgeübt werden, wobei es nicht selten geschieht, daß der Glaskonus der Injektionsspritze abbricht, weil die Wandung des aus Hartmetall hergestellten Kanülenhalters nicht nachgibt. Bei der Herstellung der Kanülenhalter und der Spritzen ergeben sich auch oft Unterschiede in den Konusmassen, besonders wenn die Spritze und der Kanülenhalter verschiedenen Ursprungs sind, so daß der Hartmetallkanülenhalter weder fest noch genügend dicht auf dem Spritzenkonus aufsitzt. Diese Nachteile könnten beseitigt werden, indem man den Kanülenhalter ganz aus Weichmetall herstellt. Da derselbe jedoch während des Sterilisierens, wenn er den Boden des Sterilisiergefäßes berührt, als Wärmeleiter dient, würde er an der Auflagefläche schmelzen. Weichmetallansätze verlieren auch- bald die Politur und werden im Gebrauch unansehnlich.Needle holder for injection syringes The one used for injection syringes Cannulas are usually attached to a neck made entirely of brass, in the conical bore of which the syringe cone is held and sealed, by wedging against the inner wall. So a secure hold and a A good seal must be achieved when attaching the needle holder to the syringe cone a strong pressure can be exerted with a simultaneous rotating movement, whereby It is not uncommon for the glass cone of the injection syringe to break off because the wall of the cannula holder made of hard metal does not yield. at There are also often differences in the manufacture of the cannula holder and the syringes in the cone dimensions, especially if the syringe and the needle holder are different Are of origin, so that the hard metal cannula holder is neither tight nor tight enough sits on the syringe cone. These drawbacks could be eliminated by the cannula holder is made entirely of soft metal. Since the same however during of sterilization, when it touches the bottom of the sterilization vessel, as a heat conductor serves, it would melt on the contact surface. Soft metal approaches also lose soon the polish and become unsightly in use.

Alle diese Übelstände beseitigt der Erfindungsgegenstand, indem die Kanüle d an einem aus Hartmetall. hergestellten Kanülenhalter e befestigt ist, dessen innere Wandung mit Weichmetall a ausgefüttert ist. Der in den Kanülenhalter e eingeführte Spritzenkonus wird nur von der Weichmetallschicht a gehalten und abgedichtet. Das Weichmetall gibt beim Aufdrücken auf den Spritzenkonus etwas nach, wodurch selbst bei abweichenden Konusmassen ohne Bruchgefahr ein sicheres Festklemmen und vollkommenes Abdichten des Kanülenhalters ermöglicht wird.The subject of the invention eliminates all these inconveniences by the Cannula d on one made of hard metal. Manufactured cannula holder e is attached, its inner wall is lined with soft metal a. The inserted into the cannula holder e Syringe cone is only held and sealed by the soft metal layer a. That Soft metal yields somewhat when it is pressed onto the syringe cone, which itself With deviating cone dimensions, secure clamping and complete without the risk of breakage Sealing of the cannula holder is made possible.

Da der Außenmantel e des Kanülenhalters aus Hartmetall besteht, ist er widerstandsfähig gegen mechanische Beanspruchung und wird durch die thermische Einwirkung während des Auskochens nicht beschädigt. Der Kanülenhalter ist auf zwei Seiten (Fig. z) oder auf vier Seiten (Fig. a) mit längs durchlaufenden Vertiefungen b versehen, damit er die Heizfläche des Sterilisiergefäßes nur mit den Kanten c des Ansatzes berührt.Since the outer jacket e of the cannula holder is made of hard metal it is resistant to mechanical stress and is affected by the thermal Effect during boiling is not damaged. The cannula holder is on two Sides (Fig. Z) or on four sides (Fig. A) with longitudinally continuous indentations b provided so that only the edges c of the approach.
