Description

Kanüle Die Erfindung betrifft eine Kanüle zum einmaligen Gebrauch, die mit einem Ansatz aus Kunststoff versehen ist. Cannula The invention relates to a single-use cannula, which is provided with a plastic approach.

Die bekannten Kanülen dieser Art sind mit dem Kunststoffansatz entweder verklebt oder verschmolzen oder in den Ansatz auf Festsitz eingeschossen. Diese drei Arten der Verbindung zwischen Kanüle und Eunststoffansatz ergeben aber in vielen Fällen keinen genügend festen Sitz, so daß es vorkommt, daß die Kanüle beim Gebrauch ein Stück in den Ansatz hineingestoßen wird, oder sogar, daß die Kanüle aus dem Ansatz herausfällt.The known cannulas of this type are either with the plastic attachment glued or fused or shot into the neck for a tight fit. These however, there are three types of connection between cannula and plastic attachment in many In some cases, the fit is not sufficiently tight, so that it happens that the cannula is in use a piece is pushed into the hub, or even that the cannula is pushed out of the Approach falls out.

Die Erfindung hat die Aufgabe, für eine zuverlässige Verbindung zwischen Kanüle und Kunststoffansatz zu sorgen die auch bei heftigem Einstoßen der Kanüle in eine Vene nicht nachgibt.The invention has the task for a reliable connection between The cannula and plastic attachment ensure that the cannula is pushed in too hard does not give way into a vein.

Dies wird dadurch erreicht, daß die Kanüle an ihrem im Ansatz zu befestigenden Ende mit einem angestauchten Flansch versehen ist und der Ansatz durch Umspritzen der Kanüle hergestellt ist.This is achieved in that the cannula is to be attached to its neck The end is provided with an upset flange and the approach by overmolding the cannula is made.

Damit der nach außen gerichtete Flansch der Kanüle genügend Halt in dem Ansatz findet, wird vorzugsweise der Ansatz in seinem hinteren Teil verdickt ausgeführt. Dieser verdickte Teil wird vorteilhaft mit Riffeln versehen, um einen sicheren Griff zu ermöglichen.So that the outward-facing flange of the cannula has sufficient hold in finds the approach, the approach is preferably thickened in its rear part executed. This thickened part is advantageously provided with corrugations to a to enable a secure grip.

Die Zeichnung zeigt Ausführungsbeispiele der Erfindung.The drawing shows exemplary embodiments of the invention.

Figur 1 ist ein Längsschnitt durch die Kanüle mit Ansatz.Figure 1 is a longitudinal section through the cannula with attachment.

Figur 2 zeigt in größerem Maßstab nur den Ansatz, wobei die Kanüle weggelassen ist, da hier nur Einzelheiten der Gestaltung des Ansatzes erklärt werden sollen.Figure 2 shows on a larger scale only the approach, with the cannula is omitted, since only details of the design of the approach are explained here should.

In Figur 1 ist die Kanüle mit 1 bezeichnet. Ihr gemäß der Erfindung zu einem Flansch gestauchtes Ende 2 läßt erkennen, daß durch Abrundung der Stauchkante ein glatter Übergang zwischen dem Hohlraum des Ansatzes und dem Inneren der Kanüle erreicht ist.The cannula is denoted by 1 in FIG. You according to the invention End 2 compressed to form a flange shows that by rounding off the compression edge a smooth transition between the cavity of the hub and the interior of the cannula is reached.

Der Kunststoffansatz 3 ist an seinem hinteren Ende 4 so verdickt, daß der Flansch 2 noch von einer starken Kunststoffschicht umhüllt ist. Der Hohlraum des Ansatzes ist in üblicher Weise mit konischer Erweiterung 5 ausgeführt, In Figur 2, bei der die Umrisse des Ansatzes etwas abweichend von Figur 1 gestaltet sind, erkennt man weiter die Riffelung 6 auf dem verdickten Teil 4.The plastic attachment 3 is thickened at its rear end 4 so that that the flange 2 is still covered by a strong layer of plastic. The cavity the approach is carried out in the usual way with a conical enlargement 5, in Figure 2, in which the outlines of the approach are designed slightly different from Figure 1, one can also see the corrugation 6 on the thickened part 4.
