Abstract

The canula (5) which serves to guide the catheter into position in the vein or other vessel has U shape. Pref. the catheter (1) and the canula (5) are separated intravenously by withdrawing the canula from the vessel. A transparent receiver (7) is used to ensure correct placing of the canula in the blood vessel as the flow of blood can be seen in the receiver. Canula and catheter have different lengths, diameters and shapes according to requirements. A radio-opaque strip (2) is provided in the catheter for radiological tracting of the correct position of the catheter in the blood vessel.

Description

Kathe tersystem betrifft Die Zusatsanmeldungfweitere verbessernde Merkmale der Patentanmeldung P 24 54 502.6 und der Hilfsgebrauchsmusteranmeldung G 74 38 357.6.Kathe tersystem concerns the additional registrationf further improving Features of patent application P 24 54 502.6 and the utility model application G 74 38 357.6.

Wesentliche Merkmale der Zusatzanmeldung sind eine nahezu U - förmige Auslegung der Kanüle, die dann auch eine intervenöse Trennung des Katheters von der Einführungskanüle ohne mechanischen, pneumatischen oder hydraulischen Drucgermöglicht sowie ein nur unwesentlicher Unterschied der Außendurchmesser von Kanüle und Katheter.The essential features of the additional application are almost U - shaped Design of the cannula, which then also separates the catheter from intervening the insertion cannula without mechanical, pneumatic or hydraulic pressure and only an insignificant difference in the outer diameter of the cannula and catheter.

Die Placierung langer Katheter kann derart erfolgen, daß ein im Katheter liegender und mit dem Dichtstopfen verbundener Dichtfaden mit Kontrastmaterial versehen ist, und somit röntgenologisch auf dem Röntgenschirm verfolgt werden kann.Long catheters can be placed with one in the catheter Provide the lying sealing thread connected to the sealing plug with contrast material and can therefore be followed radiologically on the X-ray screen.

Die sichere intervenöse Placierung der Kanüle kann mittels einem Aufnahmeteil erfolgen, das, aus transparentem Material bestehend, in dieses Aufnahmeteil einflreßendepf Blut sofort anzeigt. Es ist auch denkbar, diese Anzeige durch den transparenten Katheter selbst zu ermöglichen.The safe intervenous placement of the cannula can be achieved by means of a receiving part take place, consisting of transparent material, einflreßendepf in this receiving part Showing blood immediately. It is also conceivable to have this display through the transparent To enable catheter itself.

Ein Ausführungsbeispiel der Zusatzanmeldung zeigt Fig.1, in der das Kathetersystem in einer Seitansicht und einem Schnitt nach der Linie A-A dargestellt ist.An embodiment of the additional application is shown in FIG Catheter system shown in a side view and a section along the line A-A is.

Im Ausführungsbeispiel nach Fig.1 ist mit 1 der Katheter bezeichnet, der, beliebig lang, in der U - förmig ausgebildeten Kanüle 5 tief in das Gefäß eingeführt werden kann. Ein Dichtfaden 2 dichtet den Katheter ab und kann, mit #trastmaterial versehen, die Verfolgung der Placierung auf einem Röntgenschirm ermöglichen. Teil 3 ist eine mit dem Katheter fest verbundene Female-Kupplung und ein mit dem Dichtfaden verbundener Stopfen^4.In the exemplary embodiment according to FIG. 1, 1 denotes the catheter, which, of any length, is inserted deep into the vessel in the U-shaped cannula 5 can be. A sealing thread 2 seals the catheter and can, with #trastmaterial provided that allow tracking of the placement on an X-ray screen. part 3 is a female coupling firmly connected to the catheter and one to the sealing thread connected plug ^ 4.

Im Aufnahmeteil 7 ist die Kanüle eingepreßt, die im hinteren Teil einen Formstab 6 enthält, der den Katheter dichtend führt.In the receiving part 7, the cannula is pressed in, which is in the rear part contains a shaped rod 6 which guides the catheter in a sealing manner.

Der Formstab 7 kann auch mit einer Bohrung versehen oder entsprechendem sowie ein Aufnahmebehälter in dem Aufnahme teil 7 vorgesehen werden, damit die Placierung der Kanüle in der Vene angezeigt wird.The shaped rod 7 can also be provided with a bore or the like and a receptacle in the receiving part 7 are provided so that the placement the cannula in the vein is displayed.
