Stand der Technik : Ein System zur kontinuierlichen Blutentnahme aus einer peripheren Vene liegt in Form eines Loppellumenkatheters vor, dessen prinzipieller Aufbau aus einer Veröffentlichung von E.F. Pfeiffer et al (Horm.Met.Res.Suppl.Series 7, (1977), 95) hervorgeht. Ein System zur intermittierenden Blutentnahme und gleichzeitigen Infusion über einen axial liegenden Subclaviakatheter liegt in Form des Cordis Catheter Sheath Introducer Systems vor, das aus einem axial liegenden Katheter und einer Schleuse besteht, durch die der Katheter führt und aus der durch einen Seitenhahn Blut entnommen werden kann.State of the art: A system for continuous blood collection a peripheral vein is in the form of a double lumen catheter, its principal Structure from a publication by E.F. Pfeiffer et al (Horm.Met.Res.Suppl.Series 7, (1977), 95). A system for intermittent and simultaneous blood sampling Infusion via an axially positioned subclavian catheter is in the form of the Cordis Catheter Sheath Introducer Systems, which consists of an axially positioned catheter and a There is a sluice through which the catheter leads and from which there is a side cock Blood can be drawn.

Kritik des Standes der Technik : Für die kontinuierliche Blutentnahme bei ungünstigen peripheren Gefäßverhältnissen bzw. zentralisiertem Kreislauf ist der periphere Gefäßanschluß ungeeignet bzw. oft nicht möglich. Außerdem ist in den kleinen Gefäßen der Peripherie häufig mit mechanischen Störungen durch Anliegen des Katheters bzw. Gefäßkollaps zu rechnen.Criticism of the state of the art: For continuous blood collection in unfavorable peripheral vascular conditions or centralized circulation the peripheral vascular connection is unsuitable or often not possible. In addition, the small vessels of the periphery often with mechanical disturbances due to concerns of the catheter or vascular collapse to be expected.

Aufgabe : Mit dem vorgeschlagenen System wird ermöglicht, daß über einen zentralen Gefäßzugang infundiert und gleichzeitig kontinuierlich Blut entnommen werden kann.Task: The proposed system enables over a central vascular access is infused and blood is continuously withdrawn at the same time can be.

Lösung : Durch zwei ineinander gesteckte und miteinander verschraubte Schleusen wird ein axial liegender Katheter geführt, welcher 15 cm oder mehr über das Ende der Schleusenhülsen ragt. So kann durch den Katheter infundiert werden, zwischen Katheter und innerer Schleusenhülse Heparinlösung zugeführt werden und zwischen innerer und äußerer Schleusenhülse Blut-Heparin-Gemisch angesaugt werden, wobei die Heparin-Blut-Mischung an der Spitze der Hülsen erfolgt und kein Heparin in den Patienten gelangt.Solution: With two nested and screwed together An axially lying catheter is passed through the sheath, which is 15 cm or more across the end of the lock sleeves protrudes. So can be infused through the catheter, heparin solution is supplied between the catheter and the inner sheath and blood-heparin mixture is sucked in between the inner and outer sheath sleeve, with the heparin-blood mixture at the tip of the pods and no heparin gets into the patient.

Die Strecke, die der lnfusionskatheter über die Schleusenhiilsen hinausragt, ist mittels eines Stoppers in Enorm eines hervorstehenden Rings des Katheters und einer Überwurfmutter, die diesen Stopper an das Ansatzstück der inneren Schleuse preßt, fixiert. The distance the infusion catheter takes over the sheath sleeves protrudes, is by means of a stopper in enormous of a protruding ring of the Catheter and a union nut that attach this stopper to the end piece of the inner Lock presses, fixed.

Erzielbare Vorteile : Möglichkeit, (i) aus einem zentralen Gefäß wie der Vena Subclavia kontinuierlich Blut zu entnehmen mit dem Vorteil der geringeren Störanfälligkeit dieses Gefäßzugangs und (2) über ein und denselben Zugang gleichzeitig zu infundieren.Achievable Benefits: Ability to (i) like from a central vessel continuously withdrawing blood from the subclavian vein with the advantage of less This vascular access is susceptible to failure and (2) via one and the same access at the same time to infuse.

Beschreibung : Ein Ausführungsbeispiel dieses Systems ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.Description: An embodiment of this system is shown in the drawing and is described in more detail below.

Das Katheterset besteht aus folgenden Teilen : 1. Metallkanüle zur Subclaviapunktion mit 5 ml Spritze 2. Seldinger Draht 3. äußere Schleuse (Zeichnung) 4. Introducer passend für die äußere Schleuse 5. innere Schleuse (Zeichnung) 6. Katheter passend zur inneren Schleuse (Zeichnung) 7. bberwurfmutter (Zeichnung) Die Zeichnung zeigt das System, wie es im Gefäß zu liegen kommt. Die Hülse der äußeren Schleuse ragt 2 mm über das Hülsenende der inneren Schleuse vor und ist am Ende etwas nach axial abgerundet. Beide Schleusen sind durch einen Schraubmechanismus an ihren Ansatzstücken dicht miteinander verbunden. Um den Totraum so klein wie möglich zu halten, füllt der vordere Teil des Ansatzstückes der inneren Schleuse den Innenraum des hinteren Teils der äußeren Schleuse bis auf einen mantelförmigen Spalt fast vollständig aus. Durch die innere Schleuse kann dann der Katheter zur Infusion geführt werden, der ca. 15 cm über das Ende der Schleuse ragt, sodaß die infundierte Lösung sich nicht mit dem Blut vermischt, welches zwischen innerer und äußerer Schleuse angesaugt wird. The catheter set consists of the following parts: 1. Metal cannula for Subclavia puncture with 5 ml syringe 2. Seldinger wire 3. Outer sluice (drawing) 4. Introducer suitable for the outer lock 5. Inner lock (drawing) 6. Catheter matching the inner sheath (drawing) 7. Union nut (drawing) The drawing shows the system as it comes to rest in the vessel. The sleeve of the outer The lock protrudes 2 mm beyond the sleeve end of the inner lock and is at the end slightly rounded axially. Both locks are by a screw mechanism closely connected at their attachments. To make the dead space as small as to keep possible, the front part of the extension of the inner lock fills the interior of the rear part of the outer lock except for a jacket-shaped one Almost completely split. The catheter can then pass through the inner sheath Infusion are performed, which protrudes about 15 cm above the end of the lock, so that the infused solution does not mix with the blood flowing between the inner and the outer lock is sucked in.

Um ein Herausrutschen des Katheters zu verhindern, ist an ihm ein Stopper in Form einer ringförmigen Verdickung vorgesehen. Dieser wird mit einer Überwurfmutter an dem Ansatzstück der inneren Schleuse fixiert. To prevent the catheter from slipping out, there is a Stopper provided in the form of an annular thickening. This one comes with a Union nut fixed to the extension piece of the inner lock.

Um das entnommene Blut nicht gerinnen zu lassen, wird Heparinlösung in den Raum zwischen Katheter und innerer Schleuse gepumpt und - nach Mischung mit dem Blut an der Spitze der inneren Hülse und ohne in das Gefäßsystem des Patienten zu gelangen - Blut-Heparin-Gemisch zwischen innerer und äußerer Schleuse angesaugt. Das Mengenverhältnis zwischen Heparinlösung und Blut wird durch die Innendurchmesser des zu- und abführenden Schlauches im Bereich einer Segmentpumpe bestimmt.Heparin solution is used to prevent the blood drawn from clotting pumped into the space between the catheter and the inner sheath and - after mixing with the blood at the tip of the inner sleeve and without entering the patient's vasculature to get there - blood-heparin mixture sucked between the inner and outer lock. The quantity ratio between heparin solution and blood is determined by the inner diameter of the inlet and outlet hose determined in the area of a segment pump.
