Description
Die Erfindung betrifft eine Kanüle, bestehe« aus einem vorzugsweise aus einem aus Met' 1 gefertigten Röhrchen , da£ an Einern einen Ende in einer Spttee endet und an seinem analeren Ende an eisiea Si-aa·;.? bef?*tigt ist .The invention relates to a cannula, consisting of a tube, preferably made of metal, which ends in a spout at one end and is attached to a silicone tube at its anal end.
Bei Spritzen aller Art, die in den Körper stechen ««innen, seien es Injektionesprits Spritze;-; zur Infusion, oder zum Blut abnehmen, besteht die groBe Gefahr der Übertragung von Krankheiten, wenn man sich an ihnen nach Gebrauch verletzt.With any kind of syringe that goes into the body, whether it is an injection syringe for infusion or for taking blood, there is a great risk of transmitting diseases if you injure yourself after using them.
Bekannterweise ist & es eine der Übertragungsarten von Hepatitis und Aids. Sie gefährdet insbesondere im Gesundheitswesen tatige Personen. Die Erfindung hat daher die Aufgabe, die Kanüle einer Spritze so zu sichern, daß man eich nach "^brauch der Kanüle nicht mehr an ihr verletzen kann.It is known that it is one of the ways in which hepatitis and AIDS are transmitted. It is particularly dangerous for people working in the health sector. The invention therefore has the task of securing the needle of a syringe in such a way that it cannot cause injury after the needle has been used.
Die Problemlösung muß auch auf größtmögliche Einfachheit achttiv, damit keine großen Kosten entstehen und allgemeine Akzeptanz erzeugt wird, Erfindungsgemäß wird diese Aufgabe im speziellen Fall der BlutentnahmekanUle bzw. der Kantile zum Zweck der intravenösen Injektion dadurch gelöst, daß zwei seitlich der KanUle jeweils parallel verlaufende Federn am KanUlenansatz befestigt sind. Diese Federn laufen zur KanUlenspitze hin in einem Rundbogen aus, so, daß sie einen Kreis um die KanUlenspitze schlagen.The solution to the problem must also be as simple as possible so that no great costs are incurred and general acceptance is achieved. According to the invention, this problem is solved in the specific case of the blood collection cannula or cantilever for the purpose of intravenous injection by attaching two springs running parallel to the sides of the cannula to the cannula attachment. These springs run out in a round arc towards the cannula tip, so that they form a circle around the cannula tip.
Vorteilhaft ist weiter,auf halbem Wege zwischen den beiden Federn einen Verbindungssteg
anzubringen, der die Aufgabe hat, die Federn in der gewünschten Position zur KanUle zu halten.
Ale Material zur Fertigung der KanUlenschutzfedern wird Plastik vorgeschlagen.It is also advantageous to attach a connecting bar halfway between the two springs, which has the task of holding the springs in the desired position relative to the cannula.
Plastic is suggested as the material for manufacturing the cannula protection springs.

In allen 3 Figuren ist die tCanüle, bestehend aus einem vorzugsweise aus Metall (j gefertigtem Röhrchen 9 , das MT an seinem einen Ende in einer Spitze 5 endet, und an seinem anderen Ende an einem Ansatz 4 befestigt ist, dargestellt. Die zu verwendende Spritze wird an den Ansatz angesteckt.In all three figures, the cannula is shown, consisting of a tube 9, preferably made of metal (j) , which ends in a tip 5 at one end and is attached to an attachment 4 at its other end. The syringe to be used is attached to the attachment.
Figur 3 zeigt die Seitansicht der Kanüle mit einer der beiden Federn 6 , die am Ansatz 4 unverrückbar befestigt ist und an ihrem anderen Ende in einem Rundbogen 6 um die KanUlenspitze 5 herum ausläuft. Die Federn siad leicht so gespannt, daß sie mit ihrem Verbindungssteg 7 leicht gegen die Kanüle 9 drücken . Auf diese Art und Weise ist gewährleistet, daß Verletzungen durch die KanUlenspitze 5 infolge unbeabsichtigten BerUhrens vermieden werden.Figure 3 shows the side view of the cannula with one of the two springs 6, which is fixedly attached to the attachment 4 and ends at its other end in a round arch 6 around the cannula tip 5. The springs are slightly tensioned so that their connecting bar 7 presses lightly against the cannula 9. In this way it is ensured that injuries caused by the cannula tip 5 as a result of unintentional contact are avoided.
Den-selben Sachverhalt zeigt Figur 1 in halbschräger Aufsicht. In Figur 2 ist die-selbe Kanüle kurz vor der Venenpunktion dargestellt. Durch entsprechenden Druck auf den KanUlenansatz 4 , dargestellt durch den Finger 8 , bewegt sich die KanUlenspitze 5 dadurch aus dem Federnrundbogen 6 horava, da der Federnrundbogen auf der gestrichelt eingezeichneten Hautoberfläche 10 aufliegt. Hierbei ist die KanUlenspitze 5 bereits als unter die Hautoberfläche eingedrungen eingezeichnet. In dem Maße, wie die Kanüle 9 weiter unter die Hautoberfläche 10 vordringt, gleitet der Federnrundbogen, ähnlich einem Schlitten , über die Hautoberfläche entlang. C**'2l· <OFigure 1 shows the same situation in a semi-oblique view. In Figure 2, the same cannula is shown shortly before the venipuncture. By applying appropriate pressure to the cannula attachment 4, represented by the finger 8, the cannula tip 5 moves out of the spring arch 6, as the spring arch rests on the skin surface 10 shown in dashed lines. The cannula tip 5 is shown as having already penetrated under the skin surface. As the cannula 9 penetrates further under the skin surface 10, the spring arch slides along the skin surface, similar to a slide. C**'2l· <O
. ) Nach Herausziehen der Kanüle bewirkt die Spannung der Federn ein «automatisches ZuTiickschftappen in die Position wie in Figur 3 beschrieben. Als Material für die beiden Federn wird Kunststoff vorgeschlagen.. ) After the cannula has been pulled out, the tension of the springs causes it to automatically return to the position described in Figure 3. Plastic is suggested as the material for the two springs.
