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

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 einen Führungsstab, auch Mandrin genannt der üblicherweise im Inneren von Gefäßkathetern liegt, um diese zur leichteren Einführung in das Blutgefäß zu versteifen. Es ist bekannt, solche Führungsstäbe aus Kunststoff, Stahldraht oder künststoffummanteltem Stahldraht herzustellen. Nach dem Einbringen eines Katheters in ein Blutgefäß ist es von außerordentlicher Wichtigkeit, daß die exakte Lage der Katheterspitze im Blutgefäßsystem des Patienten lokalisiert werden kann. Dies geschah früher üblicherweise durch eine Röntgenaufnahme. Um den damit verbundenen Aufwand und die Stahlenbelastung des Patienten zu vermindern, setzt sich zunehmend die Lagekontrolle durch eine EKG-Ableitung über den Katheter durch. Dazu entfernt man üblicherweise den Führungsstab aus dem Katheter, füllt den Katheter mit Kochsalzlösung und leitet über die Kochsalzlösung mit Hilfe einer Stahlkanüle die EKG- Spannung aus dem Blutgefäß des Patienten ab. Dieses Verfahren ist sehr umständlich und mit dem Risiko bakterieller Kontamination behaftet. Die vorgestellte Erfindung ist eine Weiterentwicklung der bisher bekannten Führungsstäbe insofern, als daß eine leitende Verbindung zwischen der Spitze des Führungsstabes, die im Blutgefäß liegt, und dem Ende des Führungsstabes, das aus tlem Katheter herausragt, hergestellt wird.with the possibility of an EKG lead. The invention relates to a Guide rod, also known as the stylet, which is usually used inside vascular catheters to stiffen them for easier introduction into the blood vessel. It is known, such guide rods made of plastic, steel wire or plastic-coated Manufacture steel wire. After inserting a catheter into a blood vessel it is it is extremely important that the exact position of the catheter tip in the Blood vessel system of the patient can be localized. This used to be what usually happened through an x-ray. About the effort involved and the exposure to steel of the patient, the position control is increasingly set by an EKG lead through the catheter. To do this, you usually remove the guide rod from the Catheter, fills the catheter with saline and passes through the saline With 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 contamination afflicted. The presented invention is a further development of the previously known Guide rods insofar as that a conductive connection between the tip of the Stylus, which lies in the blood vessel, and the end of the stylet, which consists of tlem catheter protrudes.

Dadurch ist es möglich, direkt beim Einschieben des Katheters ein EKG abzuleiten, und den Katheter sofort in die richtige Position zu bringen. Die bislang vorhandenen Risiken, der Auslösung von Herzrhythmusstörungen, werden dadurch erheblich vermindert.This makes it possible to insert the catheter directly when inserting the catheter Record an EKG and immediately position the catheter in the correct position. the Previously existing risks, the triggering of cardiac arrhythmias, are thereby considerably reduced.
