Abstract

200-500 m/l blood can be pumped out, filtered and returned using a system of double ports with common vein connection plus dimensionally adjustable diaphragm as well as port diameter and volume and consistency of puncturing cannula and catheter. The system offers two separate blood input and return chambers to and from the vein and a modifiable septum diameter and material for repeated puncture, e.g. 500 times. The special cannula uses its mandril to pierce the self-sealing plastics diaphragm disc and connect beneath the skin to the blood vessel being tapped. The system necessarily includes blood filter unit prior to return to the vein, using the same system of cannulae, catheters and diaphragm etc.

Description

Bei TITAN-Port D handelt es sich um ein neues medizintechnisches Produkt. Es existieren bereits ähnliche Portsysteme zur Injektions- und Infusionsbehandlung von Medikamenten, Flüssigkeiten und Abnahme kleinerer Blutmengen. Diese sind jedoch nicht geeignet zur Gewinnung größerer Blutvolumen in kurzer Zeit z. B. für Blutwäsche. Zur Dialyse verwendet man üblichweise arteriovenöse Shunt-Anlagen (z. B. Cimino- Shunt, implantierbarer Cortex-Shunt u.ä.) sowie ein Kathetersystem, das jedoch wegen Infektionsgefahr nur kurzfristig eingeführt werden darf (3 Wochen). Zur Erreichung einer Langzeitverweildauer (2 Jahre) mit entsprechend häufigen Punktionsmöglichkeiten (ca. 500 mal) sowie Minderung der Infektionsgefahr wurde dieser TITAN-PORT D entwickelt. Dieses Problem wurde durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.TITAN-Port D is a new medical device product. It Similar port systems already exist for the injection and infusion treatment of Medicines, fluids, and taking smaller amounts of blood. However, these are not suitable for obtaining larger blood volumes in a short time e.g. B. for blood washing. Arteriovenous shunt systems (e.g. cimino- Shunt, implantable cortex shunt, etc.) and a catheter system, however may only be introduced for a short period due to the risk of infection (3 weeks). For Achieve a long-term stay (2 years) with correspondingly frequent Puncture possibilities (approx. 500 times) as well as reduction of the risk of infection was developed this TITAN-PORT D. This problem was solved by the claim 1 listed features solved.

Zwei separate Titan-Kammern mit Hohlraum und Kunststoffscheibe zur Punktion, verbunden mit einem doppellumigen Katheter zur Vene, ermöglichen die Entnahme von ca. 200-500 ml Blut/min, welches über dasselbe System auch wieder zurückgeführt werden kann. Angewendet werden kann dieses System vorteilhaft z. B. für Dialysezwecke.Two separate titanium chambers with cavity and plastic disc for puncture, connected with a double-lumen catheter to the vein, make the removal possible from approx. 200-500 ml blood / min, which again via the same system can be traced back. This system can be used advantageously z. B. for dialysis purposes.

Im Gegensatz zu bereits vorhandenen Portsystemen besteht der Vorteil dieser Erfindung darin, daß der Fluß einer solch großen Blutmenge im Verhältnis zur Zeit ermöglicht wird durchIn contrast to existing port systems, there is the advantage of this Invention in that the flow of such a large amount of blood in relation to time is made possible by

  • 1. die Verbindung von zwei separaten Kammern, zur Entnahme und Rückführung, an einen gemeinsamen Verbindungsschlauch zur Vene1. the connection of two separate chambers, for removal and return a common connecting tube to the vein
  • 2. die Änderung von Durchmesser und Material des Septums, damit mit dicken d. h. großlumigen Kanülen vielfach punktiert werden kann (ca. 500 mal), ohne Beschädigung und Undichtigkeit der selbstverschließenden Kunststoffscheibe. 2. the change in diameter and material of the septum, so with thick d. H. large-lumen cannulas can be punctured multiple times (approx. 500 times) without Damage and leakage of the self-sealing plastic disc.  
  • 3. die Verwendung einer Spezialkanüle zur Punktion mit entsprechend geeignetem Schliff und Mandrin, um die Kunststoffscheibe beim Einstich nicht zu beschädigen und kein Material auszustanzen.3. the use of a special cannula for puncture with a suitable one Cut and stylet so as not to damage the plastic disc during the puncture and no material to be punched out.
  • 4. die sichere und einfache Implantation und Verbindung mit dem Blutgefäß subcutan, d. h. unter dem Schutz der Haut, wodurch das Infektionsrisiko verringert wird.4. the safe and simple implantation and connection with the blood vessel subcutaneously, d. H. under the protection of the skin, which reduces the risk of infection becomes.
