Description

Hilfsmittel zur Befestigung abgebrochener Kanülen an Injektionsspritzen. Es wird vielfach von Ärzten als Übelstand empfunden, eine abgebrochene Kanüle nicht mehr verwenden zu können, einmal weil häufig nicht gleich eine unbeschädigte Ersatzkanüle vorhanden ist, andererseits weil der augenblickliche Gestehungspreis einer neuen Kanüle ein recht bedeutender ist. Die vorliegende Erfindung bezweckt' Jäher .die Weiterverwendbarkeit einer abgebrochenen Kanüle. Hierbei war maßgebend, daß der Arzt bei dem Einbringen der verkürzten Kanüle im wesentlichen keine anderen Handhabungen nötig haben soll, als wenn er eine'fabrikneue Kanüle aufsetzt. Es erscheint das um so mehr am Platz, weil die Kanüle gerade erst beim Gebrauch abbricht und daher deren unmittelbarer Ersatz geboten erscheint.Aids for attaching broken needles to injection syringes. Doctors often see it as a nuisance, a broken cannula is not to be able to use more, once because often not an undamaged replacement cannula exists, on the other hand because the current cost price of a new one Cannula is quite a significant one. The present invention aims to 'die Reusability of a broken cannula. It was decisive that the The physician does essentially no other manipulation when inserting the shortened cannula as if he were putting on a brand-new cannula. It appears that all the more in place because the cannula just breaks off during use and therefore whose immediate replacement appears to be necessary.

Das Wesen des Erfindungsgegenstandes liegt somit in einem geparaturstück, welches an Stelle des Kolber-s'oder Kopfes der Kanüle auf der Düse der-Spritze befestigbar ist und das Bruchstück der Kanüle festzuhalten gestattet.The essence of the subject of the invention lies in a piece of repair, which can be attached to the nozzle of the syringe in place of the piston or head of the cannula and is allowed to hold the fragment of the cannula.

Bekanntlich ist gewöhnlich die Kanüle d in dem verjüngten Ende b einer kleinen Büchse d eingelötet, oder sie wird einfach in das Loch der Büchse d eingesteckt und wird dort durch Reibung festgehalten, während die Höhlung der Büchse d mit der Bohrung e der Düse f der Spritze g in Verbindung steht (Abb. i).As is known, the cannula d is usually soldered into the tapered end b of a small sleeve d , or it is simply inserted into the hole in the sleeve d and is held there by friction, while the cavity of the sleeve d with the bore e of the nozzle f of the syringe g is connected (Fig. i).

Gemäß der Erfindung ist nun ein Reparaturstück für den die Kanüle tragenden, aus Büchse d und Konus b bestehenden Spritzenkopf vorgesehen, der in seinem hülsenförmigen Teil d' dem entsprechenden Teil d des Spritzenkopfes entspricht. Im übrigen ist der Spritzenkopf als Klemmfutter ausgebildet. In dieser Beziehung ist das neue Hilfsmittel verschiedener Abwandlungen fähig, ohne daß dadurch aus dem Schutzumfang herausgetreten würde.According to the invention, a repair piece is now provided for the syringe head, which carries the cannula and consists of a sleeve d and a cone b , which corresponds in its sleeve-shaped part d 'to the corresponding part d of the syringe head. In addition, the syringe head is designed as a clamping chuck. In this regard, the new aid is capable of various modifications without thereby departing from the scope of protection.

In der Ausführungsform nach Abb. 2 hat die Büchse dl einen hülsenförmigen Fortsatz bl mit eingezogener elastischer Tülle i, in deren Verengung die abgebrochene Kanüle & eingesteckt und festgehalten wird. Der Teil d1 wird dann einfach gegen den Teil d ausgetauscht, und die Spritze ist in der gleichen Weise verwendbar wie mit der unbeschädigten Kanüle a.In the embodiment according to Fig. 2, the sleeve dl has a sleeve-shaped Extension bl with retracted elastic sleeve i, in the narrowing of which the broken off Cannula & is inserted and held. The part d1 is then simply against replaced part d and the syringe can be used in the same way as with the undamaged cannula a.

Bei der Ausführung nach Abb. 3 nimmt ein geschlitzter Konus bz die abgebrochene Kanüle & auf, die in ihrer Lage durch einen kleinen Schrumpfring m gesichert wird, der in seiner kegeligen Bohrung der Neigung des Kegels bz folgt.In the embodiment according to Fig. 3, a slotted cone or takes the broken cannula & open that is held in place by a small shrink ring m, which is saved in its tapered bore the inclination of the Kegels bz follows.

Es genügt aber auch ein zylindrischer Fortsatz b8, der durch mehrfache Längsschlitze in Zungen gespalten ist, die durch eine Muffe ml nach dem Einführen des Kanülenstumpfes a1 zusammengepreBt werden und letztere dadurch einklemmen (Abb. q.).But it is also sufficient to have a cylindrical extension b8, which is separated by multiple Longitudinal slits split into tongues, which through a sleeve ml after insertion of the cannula stump a1 are pressed together and thereby pinch the latter (Fig. q.).
