Description
Hohlnadel Die Erfindung betrifft eine Hohlnadel, wie sie beispielsweise als kanüle in medizinischen Spritzen oder in Schreibgeräten verwendet wird.Hollow needle The invention relates to a hollow needle such as that used for example Used as a cannula in medical syringes or in writing implements.
Es ist eine Hohlnadel bekannt, die eine vollkommen glatte Oberfläche aufweist und als Injektionskanüle für medizinische Spritzen verwendet wird. Diese Hohlnadel ist an ihrem hinteren Ende mit einem Plastekonus bestückt, dessen durchgehende Bohrung aus zwei koaxil angeordneten, unterschiedliche Durchmesser besitzende Bobrungen besteht. Die unterschiedlichen t)urchmesser der Bohrungen sind vorgesehen, um der Hohlnadel einen Anschlag zu verschaffen, damit diese beim einstechen in beispielsweise eine Vene nicht in die Spritze gedrückt werden kann. nachteilig an dieser Hohlnadel ist, da# nach der Beendigung eitr intravenosen Injektion die Nadel aus dem Plastekonus gleiten und in der Vene stecken bleiben Kann, während der Konus an uer zuräckgezogenen spritze verbleibt. Ein weiterer Nachteil ist, da# nicht alle Kanülen brauchbar sind, weil bei dem umständlichen iierstellungsvert'ahren nicht in jedem Fall im Konus eine durchgehende Durchtrittsöffnung erzielt werden kann.A hollow needle is known which has a perfectly smooth surface and is used as an injection cannula for medical syringes. These Hollow needle is equipped at its rear end with a plastic cone whose continuous Bore from two coaxially arranged, different diameters possessing stanchions consists. The different diameters of the bores are provided in order to Hollow needle to provide a stop so that when piercing in, for example a vein cannot be pushed into the syringe. disadvantage of this hollow needle is because # after the completion of the purulent intravenous injection, the needle comes out of the plastic cone Can slide and get stuck in the vein while the cone is pulled back on the outside syringe remains. Another disadvantage is that # not all cannulas can be used, because not always in the cone with the cumbersome manufacturing process a through opening can be achieved.
Um diese Nachteiie zu beseitigen wurde eine Hohlnadel mit einem ain hinteren Ende angebrachten Gewinde entwickelt.To eliminate this disadvantage, a hollow needle with an ain thread attached to the rear end.
Hier wird der Flastekonus auf das Gewinde der Hohlnadel aufgespritzt. bei dieser Hohlnadel besteht die Gefahr, daß sie am Ans lauf des Gewindes abbricht oder sehr leicht aus dem Konus herausgedreht wird.Here the bottle cone is sprayed onto the thread of the hollow needle. with this hollow needle there is a risk that it will break off at the start of the thread or is very easily twisted out of the cone.
Zweck der Erfindung ist die Bereitstellung einer Hohlnadel bei der keine Gefahr des Abbrechens besteht und die in der einmal festgelegten Stellung im Konus oder im jeweiligen Dauteil unverändert verbleit.The purpose of the invention is to provide a hollow needle in the there is no risk of breaking off and in the position once determined leaded unchanged in the cone or in the respective dome.
Der Erfindung liegt die Aufgabe zugrunde, eine Hohlnadel zu schaffen, die Üich in honen und ähnlichen Bauteilen so anordnen läßt, daß ein einwandfreier Durchgang durch Hohlnadel und Ronus gewährleistet bleibt, die abbruchsicher ist und bei der ein Herausschrauben aus dem konus oder aus dem an ihr befestigen bauteil unmöglich ist.The invention is based on the object of creating a hollow needle, the Üich can be arranged in honing and similar components so that a flawless Passage through the hollow needle and ronus remains guaranteed, which is break-proof and when unscrewing from the cone or from the component attached to it is impossible.
Erfindungsgemä# wird das durch spanlos auf der Hohlnadel angebrachte, nach aer Kanülenmitte flach auslaufende Vertiefungen erreicht.According to the invention, the attached by non-cutting on the hollow needle, Reached depressions tapering towards the center of the cannula.
Vorteilhaft hieran ist, da# durch die allmählich auslaufenden Vertiefungen, die beim Gewinde vorhandene nachteilige Kerbwirkung ausgeschlossen wird, wodurel die Nadel abbruchsicher ist. Ein weiterer Vorteil ist, da# ein Herausdrehen der Hohlnadel infolge der willkürlich wählbaren Vertiefungsformeh verhindert wird. iLnhand einer Zeichnung soll ein Ausführungsbeispiel die Erfindung näher erläutern.The advantage here is that # due to the gradually tapering depressions, the negative notch effect present in the thread is excluded, wodurel the needle is break-proof. Another advantage is that # the Hollow needle is prevented due to the arbitrarily selectable recess shape. iLnhand a drawing is intended to explain an embodiment of the invention in more detail.
Eine Hohlnadel 1 ist an ihrem hinteren binde mit spanlos hergestellten, in ihrer Form frei wählbaren Vertiefungen 2 versehen. Diese Vertiefungen 2 laufen nach der Mitte der Hohlnadel 1 flach aus.A hollow needle 1 is on its rear bandage with non-cutting manufactured, Provided in their shape freely selectable wells 2. These wells 2 run towards the middle of the hollow needle 1.
