Abstract

The invention relates to a guiding rod for the introduction of a vascular catheter whose intracorporeal tip is conductive and in electrically conducting contact with a contact on the extracorporeal end-piece of the guiding rod. The extracorporeal end-piece is expediently designed such that commercially available ECG cables can be connected directly.

Description

Translated fromGerman

Führungsstab zum Einbringen eines Katheters in ein BlutgefäßGuide rod for inserting a catheter into a blood vessel

mit der Möglichkeit einer EKG- Ableitung Die Erfindung betrifft einenFührungsstab, auch Mandrin genannt der üblicherweise im Inneren von Gefäßkatheternliegt, um diese zur leichteren Einführung in das Blutgefäß zu versteifen. Es istbekannt, solche Führungsstäbe aus Kunststoff, Stahldraht oder künststoffummanteltemStahldraht herzustellen. Nach dem Einbringen eines Katheters in ein Blutgefäß istes von außerordentlicher Wichtigkeit, daß die exakte Lage der Katheterspitze imBlutgefäßsystem des Patienten lokalisiert werden kann. Dies geschah früher üblicherweisedurch eine Röntgenaufnahme. Um den damit verbundenen Aufwand und die Stahlenbelastungdes Patienten zu vermindern, setzt sich zunehmend die Lagekontrolle durch eine EKG-Ableitungüber den Katheter durch. Dazu entfernt man üblicherweise den Führungsstab aus demKatheter, füllt den Katheter mit Kochsalzlösung und leitet über die Kochsalzlösungmit Hilfe einer Stahlkanüle die EKG- Spannung aus dem Blutgefäß des Patienten ab.Dieses Verfahren ist sehr umständlich und mit dem Risiko bakterieller Kontaminationbehaftet. Die vorgestellte Erfindung ist eine Weiterentwicklung der bisher bekanntenFührungsstäbe insofern, als daß eine leitende Verbindung zwischen der Spitze desFührungsstabes, die im Blutgefäß liegt, und dem Ende des Führungsstabes, das austlem Katheter herausragt, hergestellt wird.with the possibility of an EKG lead. The invention relates to aGuide rod, also known as the stylet, which is usually used inside vascular cathetersto stiffen them for easier introduction into the blood vessel. It isknown, such guide rods made of plastic, steel wire or plastic-coatedManufacture steel wire. After inserting a catheter into a blood vessel it isit is extremely important that the exact position of the catheter tip in theBlood vessel system of the patient can be localized. This used to be what usually happenedthrough an x-ray. About the effort involved and the exposure to steelof the patient, the position control is increasingly set by an EKG leadthrough the catheter. To do this, you usually remove the guide rod from theCatheter, fills the catheter with saline and passes through the salineWith the help of a steel cannula, the ECG voltage is taken from the patient's blood vessel.This procedure is very cumbersome and carries the risk of bacterial contaminationafflicted. The presented invention is a further development of the previously knownGuide rods insofar as that a conductive connection between the tip of theStylus, which lies in the blood vessel, and the end of the stylet, which consists oftlem catheter protrudes.

Dadurch ist es möglich, direkt beim Einschieben des Katheters einEKG abzuleiten, und den Katheter sofort in die richtige Position zu bringen. Diebislang vorhandenen Risiken, der Auslösung von Herzrhythmusstörungen, werden dadurcherheblich vermindert.This makes it possible to insert the catheter directly when inserting the catheterRecord an EKG and immediately position the catheter in the correct position. thePreviously existing risks, the triggering of cardiac arrhythmias, are therebyconsiderably reduced.
