Description

Die Erfindung betrifft eine dreilumige Katheter­ vorrichtung zur Infusion und Blutentnahme mit einem ersten Katheter, der konzentrisch von ei­ nem zweiten Katheter umgeben ist.The invention relates to a three-lumen catheter device for infusion and blood sampling with a first catheter concentric with egg is surrounded by a second catheter.

Eine Vorrichtung der gattungsgemäßen Art ist aus der EP-PS 00 00 041 entnehmbar. Die dort ge­ zeigte Vorrichtung besteht aus einem axial ver­ laufenden Katheter, der von einem zweiten Ka­ theter konzentrisch umgeben ist, dessen proxi­ males Ende noch vor der des ersten Katheters liegt. Diese Vorrichtung wird zu Dialysezwecken zur Entnahme und Rückführung von Blut einge­ setzt, wobei grundsätzlich große Blutmengen entnommen, von dort zum Reinigungsgerät gelan­ gen und wieder zum Körper zurückgelangen. Sie besitzt demnach zwei Katheter, wobei der zen­ trale, der gleichzeitig der Führung der Punk­ tionskanäle dient, der Entnahme und der äußere der nach der Reinigung erfolgenden Blutrück­ führung dient. Bei der Dialyse werden ständig relativ große Blutmengen dem Körper entnommen. Bei der Entnahme geringer Mengen stellt sich als nachteilig heraus, daß das Blut ein hohes Maß an Gerinnungsfähigkeit aufweist, so daß der Transport zu einer Analysestation grund­ sätzlich unmöglich ist.A device of the generic type is can be found in EP-PS 00 00 041. The ge there showed device consists of an axially ver running catheter from a second Ka theter is surrounded concentrically, its proxi end before the first catheter lies. This device is used for dialysis purposes for taking and returning blood sets, basically large amounts of blood removed, from there to the cleaning device and get back to the body. they therefore has two catheters, the zen trale, who is simultaneously leading the punk tion channels, the removal and the external the blood return after cleaning leadership serves. During dialysis are constantly Relatively large amounts of blood drawn from the body. When small quantities are withdrawn as a disadvantage that the blood is high Has level of coagulation ability, so that the transport to an analysis station is additionally impossible.

Hiervon ausgehend hat sich die Erfindung die Schaffung einer Kathetervorrichtung zur Aufgabe gemacht, mit deren Hilfe die kontinuierliche Entnahme geringer Blutmengen bei gleichzeitiger Infusion möglich wird.Proceeding from this, the invention has Creation of a catheter device for the task made with the help of the continuous Withdrawal of small amounts of blood with simultaneous Infusion becomes possible.

Gelöst wird diese Aufgabe bei einem Katheter nach dem Oberbegriff erfindungsgemäß da­ durch, daß über den ersten Katheter die Infusion und über den zweiten Katheter die Blutentnahme erfolgt, wobei innerhalb desselben ein weiterer, konzentrisch zum zweiten Katheter befindlicher dritter Katheter angeordnet ist, dessen proxi­ males Ende innerhalb des äußeren zweiten Kathe­ ters endet und der Raum zwischen diesem und dem ersten Katheter der Zufuhr einer gerinnungshem­ menden Lösung dient.This object is achieved according to the invention in a catheter according to the preamble through that the infusion over the first catheter and taking blood via the second catheter takes place, within which another, concentric to the second catheter third catheter is arranged, the proxi males end within the outer second kathe ters ends and the space between this and the first catheter supplying an anticoagulant serving solution.

Über den dritten Katheter wird dann aufgrund der räumlichen Anordnung einzig und allein dem zu entnehmenden Blut ein die Gerinnung verhindern­ des Antikoagulanz beigemischt. Es wird dadurch möglich, das entnommene Blut auch über größere Entfernung zu transportieren und einer Analyse­ station zuzuführen.The third catheter is then used due to the spatial arrangement only to that taking blood to prevent coagulation added to the anticoagulant. It will possible, the drawn blood also over larger Transport distance and analysis feed station.

Die Entnahme auch geringer Blutmengen wird da­ mit durchführbar. Gleichzeitig erfolgt über den ersten Katheter das Einbringen einer Infusions­ lösung, deren Stärke und Konzentration entspre­ chend dem in der Analysestation ermittelten Wert steuerbar ist. Im konkreten Fall kann der Wert des Blutzuckers ermittelt und gleichzeitig ent­ sprechend dem Ergebnis die Infusion des Insulins eingestellt werden. Die erfindungsgemäße Vorrich­ tung erlaubt die Entnahme vergleichsweise gerin­ ger Blutmengen, so daß für den Patienten keine nennenswerten Schwächungen mehr auftreten. Wei­ ter ist von entscheidender Bedeutung, daß das zugeführte Antikoagulanz vollständig dem entnom­ menen Blut beigemischt wird und sich nicht im Körper ausbreiten kann, was eine Verzögerung des Heilprozesses zur Folge hätte. Wenn der der Zu­ führung der Infusion dienende innere Katheter weiter außerhalb endet, ist dem entnommenen Blut keine Infusionslösung beigefügt, so daß die Mes­ sung völlig unbeeinflußt vorgenommen werden kann. Als Vorteil ist noch anzusehen, daß die Entnahme des Blutes aus einem zentralen Gefäß erfolgen kann, so daß die bei peripheren Entnahmen auftre­ tenden Komplikationen und Störungen nicht zu be­ fürchten sind.The withdrawal of even small amounts of blood is there with feasible. At the same time, the first catheter introducing an infusion solution whose strength and concentration correspond according to the value determined in the analysis station is controllable. In the specific case, the value of blood sugar is determined and at the same time ent speaking of the result infusion of insulin can be set. The Vorrich invention tion allows the removal comparatively low  blood quantities, so that none for the patient noteworthy weakenings occur more. Wei It is crucial that the anticoagulant supplied completely from the ENT to whom blood is added and not in the Body can spread, which is a delay of Healing process would result. If the the To Guiding the inner catheter used for infusion ending outside is the blood drawn no solution for infusion added, so that the Mes solution can be made completely unaffected. Another advantage is that the removal of blood from a central vessel can, so that occurs in peripheral withdrawals complications and disorders not to be are afraid.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden nä­ her beschrieben.An embodiment of the invention is in the Drawing shown and is in the following nä described here.

Sie zeigt in schematisch gehal­ tener Darstellung einen Schnitt in axialer Rich­ tung durch die erfindungsgemäße Kathetervorrich­ tung.It shows schematically Gehal representation of a section in the axial direction tion by the catheter device according to the invention tung.

Ein erster Katheter (1), der der Zuführung der In­ fusionslösung dient, ist konzentrisch von einem zweiten Katheter (2) umgeben. An seinem proxima­ len Ende endet der zweite äußere Katheter (2) vor dem, also innerhalb des ersten Katheters (1). Der zweite Katheter (2) wird zur Entnahme des Blu­ tes genutzt.A first catheter ( 1 ), which is used to supply the infusion solution, is concentrically surrounded by a second catheter ( 2 ). At its proximal end, the second outer catheter ( 2 ) ends before, ie within the first catheter ( 1 ). The second catheter ( 2 ) is used to remove the blood.

Für die Erfindung entscheidend ist, daß innerhalb des zweiten Katheters (2) ein dritter Katheter (3) angeordnet ist, dessen proximales Ende sei­ nerseits innerhalb der des äußeren Endes des zweiten Katheters (2) endet. Der Raum zwischen dem dritten Katheter (3) und dem ersten Katheter (1) dient der Zufuhr einer gerinnungshemmenden Lösung.It is decisive for the invention that a third catheter ( 3 ) is arranged within the second catheter ( 2 ), the proximal end of which is on the other side ending within that of the outer end of the second catheter ( 2 ). The space between the third catheter ( 3 ) and the first catheter ( 1 ) serves to supply an anticoagulant solution.

Das Ende des zweiten Katheters (2) ragt etwas über das Ende des dritten Katheters (3) hin­ aus und ist am Ende zusätzlich axial abgerun­ det. Die beiden Katheter (2, 3) sind über einen Schraubmechanismus (4) an ihren Ansatzstücken (5, 6) miteinander verbunden. Um den Totraum mög­ lichst klein zu halten, füllt der vordere Teil des Ansatzstückes (6) des dritten Katheters (3) den Innenraum des hinteren Teils des Ansatzstüc­ kes (5) des äußeren, zweiten Katheters (2) bis zu einem mantelförmigen Spalt fast vollständig aus. Der erste Katheter (1) wird zur Infusion benutzt und steht ca. 15 cm über das Ende der beiden anderen Katheter (2, 3) über, so daß die infudierte Lösung sich nicht mit dem Blut ver­ mischt, welches zwischen zweitem und drittem Ka­ theter angesaugt und abgeleitet wird.The end of the second catheter ( 2 ) protrudes somewhat beyond the end of the third catheter ( 3 ) and is additionally axially rounded at the end. The two catheters ( 2, 3 ) are connected to each other by a screw mechanism ( 4 ) at their attachments ( 5, 6 ). In order to keep the dead space as small as possible, the front part of the extension ( 6 ) of the third catheter ( 3 ) fills the interior of the rear part of the extension ( 5 ) of the outer, second catheter ( 2 ) almost completely up to a jacket-shaped gap out. The first catheter ( 1 ) is used for infusion and protrudes about 15 cm above the end of the other two catheters ( 2, 3 ) so that the infused solution does not mix with the blood which flows between the second and third catheters is sucked in and discharged.

Um das Herausrutschen des ersten Katheters (1) zu verhindern, ist an ihm ein Stopper (7) in Form einer ringförmigen Verdickung vorgesehen. Sie wird mit Hilfe einer Überwurfmutter (8) am An­ satzstück (6) des Katheters (3) fixiert.In order to prevent the first catheter ( 1 ) from slipping out, a stopper ( 7 ) in the form of an annular thickening is provided on it. It is fixed with the help of a union nut ( 8 ) on the set piece ( 6 ) of the catheter ( 3 ).

Um das entnommene Blut nicht gerinnen zu lassen wird eine gerinnungshemmende Lösung z. B. Heparin in den Raum zwischen Katheter (1) und dem dritten Katheter (3) gepumpt und - nach Mischen mit dem Blut an der Spitze des dritten Katheters (3) bzw. innerhalb des zweiten Katheters (2) und ohne in das Gefäßsystem des Patienten zu gelangen - das Blut-Heparin-Gemisch zwischen dem zweiten (2) und dem dritten Katheter (3) angesaugt. Das Men­ genverhältnis zwischen Heparin und Blut wird durch den Innendurchmesser des zu- und abführen­ den Schlauches im Bereich der Förderpumpe bzw. deren Einstellung bestimmt.In order not to let the blood drawn coagulate, an anticoagulant solution z. B. heparin pumped into the space between the catheter ( 1 ) and the third catheter ( 3 ) and - after mixing with the blood at the tip of the third catheter ( 3 ) or within the second catheter ( 2 ) and without in the vascular system of To reach patients - the blood-heparin mixture is sucked in between the second ( 2 ) and the third catheter ( 3 ). The quantitative relationship between heparin and blood is determined by the inner diameter of the supply and discharge of the hose in the area of the feed pump or its setting.
