Description

Injektionsspritze. In dem Patent 338830 ist eine Injektionsnadel geschützt, beider die eigentliche Nadel a in ihrem Innern mit .einem weichen bzw. biegsamen, einer Bruchgefahr nicht ausgesetzten Röhrchen c ausgestattet ist und mit diesem als Innennadel zu; bezeichnenden Röhrchen c an der Nadelspitze d durch Lot oder andere geeignete Mittel fest verbunden ist.Injection syringe. In the patent 338830 an injection needle is protected, in which the actual needle a is equipped in its interior with .einem soft or flexible tube c, which is not exposed to the risk of breakage, and closes with this as an inner needle; denoting tube c is firmly connected to the needle tip d by solder or other suitable means.

Die Verlötung der Verbindung der Innennadel c mit der eigentlichen Nadel ax an der Spitze machte bisher erhebliche Schwierigkeiten, weil bei der Verlötung leicht das Rohr der Innennadel verstopft wird.The soldering of the connection of the inner needle c with the actual The needle ax at the tip has so far caused considerable difficulties because of the soldering the tube of the inner needle becomes easily clogged.

Um diesen Übelstand zu vermeiden, wird die Verbindung ,der Innennadel c mit der Außennadel durch Verlötung in folgender Weise her-Mgeführt.In order to avoid this inconvenience, the connection, the inner needle c with the outer needle by soldering in the following way.

Die Außennadel wird in der Nähe der Spitze mit einer Ausschleifung e versehen, bevor die Innennadel c in die Außennadel eingeführt wird. Durch diese Ausschleifung e, welche gewissermaßen ein Fenster bildet, erscheint die Innennadel c. In dieses Fenster c kann das weiche Lat feingefüllt und die Aushöhlung edadurch ausgefüllt werden, so daß eine gute und sichere Verbindung zwischen Innennadel c und Außennadel a. herbeigeführt ist, die eine Verschiebung der beiden Röhrchen gegeneinander ausschließt. Die Lötstelle f kann geeignet glatt poliert werden.The outer needle is looped out near the tip e provided before the inner needle c is inserted into the outer needle. Through this The inner needle appears in loop e, which in a sense forms a window c. The soft lat can be finely filled into this window c and the hollowing out thereby be filled in, so that a good and secure connection between the inner needle c and outer needle a. is brought about that a displacement of the two tubes against each other excludes. The soldering point f can be polished smoothly in a suitable manner.
