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. TITAN port D is a new medical product. Es existieren bereits ähnliche Portsysteme zur Injektions- und Infusionsbehandlung von Medikamenten, Flüssigkeiten und Abnahme kleinerer Blutmengen. There already exist systems for similar port injection and infusion treatment of drugs, fluids and smaller amounts of blood loss. Diese sind jedoch nicht geeignet zur Gewinnung größerer Blutvolumen in kurzer Zeit z. However, these are not suitable for obtaining greater blood volume in a short time for. B. für Blutwäsche. As for hemodialysis. 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). For dialysis is usually used as arteriovenous shunt systems (z. B. Cimino- shunt, implantable Cortex-shunt, etc.) and a catheter system that may be introduced but only in the short term because of risk of infection (3 weeks). Zur Erreichung einer Langzeitverweildauer (2 Jahre) mit entsprechend häufigen Punktionsmöglichkeiten (ca. 500 mal) sowie Minderung der Infektionsgefahr wurde dieser TITAN-PORT D entwickelt. To achieve a long-term stay (2 years) with correspondingly frequent puncture venues (about 500 times), as well as reducing the risk of infection of the TITAN-PORT D was developed. Dieses Problem wurde durch die im Patentanspruch 1 aufgeführten Merkmale gelöst. This problem was solved by the features recited in patent claim 1.

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. Two separate chambers with titanium cavity and plastic disk to puncture, combined with a double-lumen catheter to the vein, allow the removal of approximately 200-500 ml blood / min, which can be returned via the same system again. Angewendet werden kann dieses System vorteilhaft z. this system can be advantageously applied for. B. für Dialysezwecke. As 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 durch Unlike existing port systems, the advantage of this invention is 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 Vene 1 the connection of two separate chambers for the collection and recirculation, to a common connecting tube to the vein
  • 2. die Änderung von Durchmesser und Material des Septums, damit mit dicken dh großlumigen Kanülen vielfach punktiert werden kann (ca. 500 mal), ohne Beschädigung und Undichtigkeit der selbstverschließenden Kunststoffscheibe. 2. the change of diameter and material of the septum, so that can be punctured with thick ie large-bore needles often (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. stamp out the use of a special needle to puncture with a correspondingly suitable grinding and stylet so as not to damage the plastic disc during penetration and no material.
  • 4. die sichere und einfache Implantation und Verbindung mit dem Blutgefäß subcutan, dh unter dem Schutz der Haut, wodurch das Infektionsrisiko verringert wird. 4. safe and easy implantation and connection to the blood vessel subcutaneously, that is causing the risk of infection is reduced under the protection of the skin.

Claims (1)

  1. Verfahren zur Gewinnung einer großen Blutmenge über ein unter der Haut implantiertes Port-System mit Verbindung zu einer Vene, dadurch gekennzeichnet, daß über ein doppeltes Portsystem mit gemeinsamem Anschluß an eine Vene durch entsprechende Ausmaße der Membran, des Portdurchmessers sowie des Lumens und Beschaffenheit der Punktionskanüle und der Katheter eine Blutvolumenmenge von ca. 200-500 ml/min entnommen sowie nach Filterung über dasselbe System zurückgepumpt werden kann. A process for obtaining a large amount of blood via an implanted under the skin port system with connection to a vein, characterized in that a double port system with a common connection to a vein with the appropriate dimensions of the membrane, the port diameter, and of the lumen and nature of the puncture needle and the catheter can be removed from a blood volume amount of about 200-500 ml / min and pumped back after filtering by the same system.
