Description

Die vorliegende Erfindung betrifft eine Metallkanüle, die bis zu ihrem Schliff bzw. bis kurz davor von einem flexiblen Katheter oder einer Kanüle aus einem flexiblen Kunststoff überzogen ist und die zu deren Einführen in ein Blutgefäß dient. The present invention relates to a metal cannula to its cut or until shortly before covered by a flexible catheter or cannula of a flexible plastic material and which serves for its introduction into a blood vessel.

Kunststoffkanülen und Katheter werden in der Medizin zum Zuführen von Blut oder Infusionslösungen in das Gefäßsystem von Patienten verwendet. Plastic cannulas and catheters are used in medicine for supplying blood or infusion solutions in the vascular system of the patient. Die Kunststoffkanüle oder der Katheter werden mit Hilfe einer Metallkanüle, die sich in deren Inneren befindet, durch die Haut sowie das Gewebe gestochen und in ein Blutgefäß eingeführt. The plastic cannula or the catheter with the aid of a metal cannula that is located in the interior thereof, pierced through the skin and the tissue and inserted into a blood vessel. Nach der Punktion wird die Metallkanüle herausgezogen, so daß nur die Kunststoffkanüle oder der Katheter in dem Blutgefäß des Patienten verbleibt. After the puncture, the metal cannula is pulled out, so that only the plastic cannula or catheter remains in the patient's blood vessel.

Bei bekannten Einrichtungen ist der Metallteil der Kanüle starr, so daß beim Einführen der Kanüle in das Gewebe ein bestimmter Einstichwinkel nicht unterschritten werden kann. In known devices, the metal portion of the cannula is rigid, so that a specific injection angle can not be undercut during insertion of the cannula into the tissue.

Aufgabe der vorliegenden Erfindung ist es daher, durch die Verbiegbarkeit des Metallteils der Kanüle diesen Einstichwinkel zu vergrößern. Object of the present invention is, therefore, by the deformability of the metal part of the cannula to enlarge this insertion angle.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Metallkanüle in einem mittleren Abschnitt (in Längsrichtung) an der Ober- und Unterseite Öffnungen oder Durchbrechungen aufweist, die eine Flexion der Metallkanüle nach oben und unten zulassen. This object is inventively achieved in that the metal cannula has in a middle section (in longitudinal direction) at the top and bottom openings or perforations, which permit a flexion of the metal cannula up and down. Auf diese Weise wird beim Einführen der Metallkanüle in bezug zum Einstichwinkel eine größere Freiheit erreicht. In this way, the insertion of the metal cannula with respect to the insertion angle greater freedom is achieved. Dabei können beispielsweise in Längsrichtung hintereinander angeordnete durch Materialstege der Metallkanüle beabstandete etwa rechteckige Öffnungen an Ober- und Unterseite in diesem mittleren Abschnitt der Metallkanüle vorgesehen sein. Here may arranged by material webs of the metal cannula spaced substantially rectangular openings at upper and lower sides in this central portion of the metal cannula can be provided for example in the longitudinal direction one behind the other. Alternativ dazu können beispielsweise auch in Längsrichtung hintereinander angeordnete beabstandete parallele quer zur Längsachse der Metallkanüle ausgerichtete Schlitze vorgesehen sein, die schmaler sind als die vorgenannten rechteckigen Öffnungen. Alternatively, successively arranged spaced parallel aligned transverse to the longitudinal axis of the metal cannula slits may for example be provided, which are narrower than the aforementioned rectangular openings in the longitudinal direction. Dabei ist es bevorzugt, diese Schlitze alternierend anzuordnen, dh, daß in der Projektion in die Ebene betrachtet sich jeweils Schlitze in der Oberseite der Kanüle und Schlitze in der Unterseite der Kanüle in Längsrichtung gesehen abwechseln. In this case, it is preferable to arrange these slits alternately, ie that in projection in the plane in each case slits in the top of the cannula and the slots in the bottom of the cannula viewed alternate viewed in the longitudinal direction.

Im folgenden wird die vorliegende Erfindung anhand von Ausführungsbeispielen unter Bezugnahme auf die beiliegenden Zeichnungen näher beschrieben. In the following the present invention will be described in more detail by means of embodiments with reference to the accompanying drawings. Dabei zeigen show Here

Zunächst wird auf die Fig. 1 Bezug genommen. Referring first to FIG. 1, reference. Die in den Zeichnungen dargestellte erfindungsgemäße Kanüle besteht aus einer innenliegenden im Prinzip rohrförmigen Metallkanüle 1 , die an ihrem vorderen Einstichende spitz ist. The cannula according to the invention illustrated in the drawings consists of an inner tubular, in principle, a metal cannula 1, which is pointed at its front end puncture. Die Metallkanüle 1 ist von einem durchsichtigen Kunststoffschlauch 2 überzogen, der nach dem Herausziehen der Metallkanüle 1 im Blutgefäß des Patienten verbleibt. The metal cannula 1 is covered by a transparent plastic tube 2, which remains after extraction of the metal cannula 1 in the blood vessel of the patient. Gemäß der Erfindung sind mehrere in Längsrichtung hintereinander angeordnete durch Materialstege der Metallkanüle beabstandete in der Draufsicht etwa rechteckige Öffnungen 4 in der Metallkanüle vorgesehen und zwar wie sich aus der Draufsicht und Unteransicht ergibt befinden sich diese rechteckigen Öffnungen, die sich natürlich über die Krümmung der rohrförmigen Metallkanüle erstrecken, sowohl an der Unterseite der Metallkanüle als auch an der Oberseite der Metallkanüle. According to the invention a plurality of longitudinally arranged behind one another by material webs of the metal cannula spaced in plan view approximately rectangular openings 4 provided in the metal cannula and indeed as can be seen from the top view and bottom view are these rectangular openings, which, of course, on the curvature of the tubular metal cannula extending, at both the bottom of the metal needle as well as on top of the metal cannula.

Die Darstellung der Fig. 2 zeigt eine alternative Variante der erfindungsgemäßen Kanüle. The illustration of FIG. 2 shows an alternative variant of the cannula according to the invention. Diese besteht wiederum aus der innenliegenden prinzipiell rohrförmigen Metallkanüle 1 , die von einem durchsichtigen Kunststoffschlauch 2 überzogen ist. This in turn consists of the inner principle tubular metal cannula 1, which is covered by a transparent plastic tube. 2 Bei dieser Ausführungsform der Erfindung sind in der Metallkanüle 1 in Längsrichtung parallel mit Abstand angeordnete Schlitze 3 sowohl an der Oberseite als auch an der Unterseite der Metallkanüle 1 angeordnet. In this embodiment of the invention, are arranged both at the top and at the bottom of the metal cannula 1 in the metal cannula 1 having spaced parallel slots in the longitudinal direction. 3 Dabei ist wie bei der obenbeschriebenen Ausführungsform zunächst ein durchgehender Abschnitt der Metallkanüle im vorderen Bereich der Spitze ohne Schlitze vorgesehen, der also starr ist und die Schlitze 3 erstrecken sich über einen mittleren Bereich der Kanüle in Längsrichtung, der dadurch flexibel wird und an den sich zum hinteren Ende hin wiederum ein starrer Bereich der Metallkanüle ohne Schlitze anschließen kann. In this case, as in the above described embodiment, a continuous portion of the metal cannula is initially provided in the front region of the tip without slots, ie the rigid and the slots 3 extend across a central region of the cannula in the longitudinal direction, which is thereby flexible and is adjoined by the in turn may be followed without slots rear end a rigid portion of the metal cannula. Wie aus der Draufsicht, der Ansicht von unten und der Seitenansicht ersichtlich ist, sind die quer zur Längsrichtung angeordneten Schlitze 3 so angeordnet, daß sich Schlitze an der Oberseite und Schlitze an der Unterseite der Metallkanüle jeweils abwechseln. As can be seen from the plan view, the bottom view and the side view transversely to the longitudinal direction arranged slots 3 are arranged so that slots on the top and slots on the underside of the metal cannula alternate respectively. Aufgrund dieser alternierenden Anordnung liegt einem Schlitz 3 in der Oberseite ein durchgehender Abschnitt der Unterseite gegenüber und umgekehrt liegt einem Schlitz in der Unterseite ein durchgehender Bereich der Oberseite gegenüber. Because of this alternating arrangement of a slit 3 is located in the top of a continuous portion of the bottom up and vice versa a slot located in the bottom of a continuous region of the top opposite.
