Description
Die Erfindung betrifft eine Kathetervorrichtung nach dem Oberbegriff des Anspruchs 1.The The invention relates to a catheter device according to the preamble of claim 1.
Eine
Kathetervorrichtung dieser Art ist aus
Der radial nach innen vorstehende Vorsprung am Katheterhalter zur Fixierung des Federclip im Katheterhalter erfordert hinsichtlich Herstellung und Montage einen gewissen Aufwand. Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Kathetervorrichtung dieser Art so auszubilden, dass sie einfacher hergestellt und montiert werden kann, ohne dass die Haltefunktion des Federclip im Katheterhalter beeinträchtigt wird.Of the radially inwardly projecting protrusion on the catheter holder for fixation the spring clip in the catheter holder requires in terms of manufacturing and Assembly a certain effort. The invention is therefore the The object of the invention is to design a catheter device of this type in such a way that that it is easier to manufacture and assemble without the holding function of the spring clip in the catheter holder is impaired.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale im kennzeichnenden Teil des Anspruchs 1 gelöst. Dadurch, dass der Federclip nur durch Verkeilen oder Verkrallen der Ecken mit der Innenfläche des Katheterhalters in diesem gehalten wird, bis die Eingriffseinrichtung an der Nadel mit der Eingriffseinrichtung am Federclip beim Zurückziehen der Nadel zusammenwirkt, ergibt sich eine einfachere Gestaltung des Katheterhalters und eine einfachere Montage.These The object is achieved by the Characteristics solved in the characterizing part of claim 1. Thereby, that the spring clip only by wedging or clawing the corners with the inner surface held in the catheter holder in this until the engagement means on the needle with the engagement device on the spring clip when retracting the Needle cooperates, results in a simpler design of the Catheter holder and easier assembly.
