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 triple-lumen catheter apparatus for infusion and blood collection with a first catheter, which is concentrically surrounded by egg nem second catheter.

Eine Vorrichtung der gattungsgemäßen Art ist aus der EP-PS 00 00 041 entnehmbar. A device of the generic type can be taken from EP-PS 00 00 041st 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. The ge there showed device consists of an axially running ver catheter which is concentrically surrounded by a second Ka theter whose proximal end males is still ahead of the first catheter. 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. This device is set to dialysis purposes for removal and return of blood is, in principle taken from large amounts of blood, gene gelan from there to the cleaning device and then jump back to the body. 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. Accordingly, it has two catheter, the spectral zen, which also serves the guiding of the puncture canals, the removal and the outer of the post cleaning blood recirculation is used. Bei der Dialyse werden ständig relativ große Blutmengen dem Körper entnommen. In dialysis, relatively large amounts of blood are taken from the body permanently. 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. Upon removal of small amounts is found to be disadvantageous that the blood has a high degree of clotting ability, so that the transportation is in principle impossible to an analysis station.

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 made to provide a catheter device for the object, by means of which the continuous removal of small amounts of blood with simultaneous infusion is 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 there through with a catheter according to the preamble in that the blood collection is performed via the first catheter, the infusion and via the second catheter, inside the same another concentrically befindlicher the second catheter third catheter is arranged, the proximal males end terminates within the outer second Kathe ters and the space between this and the first catheter, the supply of a gerinnungshem Menden solution is used.

Über den dritten Katheter wird dann aufgrund der räumlichen Anordnung einzig und allein dem zu entnehmenden Blut ein die Gerinnung verhindern des Antikoagulanz beigemischt. the anticoagulant is via the third catheter then due to the spatial arrangement solely the blood to be taken prevent the clotting admixed. Es wird dadurch möglich, das entnommene Blut auch über größere Entfernung zu transportieren und einer Analyse station zuzuführen. It is thereby possible to transport the collected blood over longer distance and to supply to an analysis station.

Die Entnahme auch geringer Blutmengen wird da mit durchführbar. The withdrawal also small amounts of blood is there with feasible. 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. At the same time via the first catheter introducing an infusion solution, whose strength and concentration entspre is accordingly controlled to the value determined in the analysis station. Im konkreten Fall kann der Wert des Blutzuckers ermittelt und gleichzeitig ent sprechend dem Ergebnis die Infusion des Insulins eingestellt werden. In the specific case, the value of blood sugar can be determined and at the same time the result of the infusion of insulin can be set accordingly. Die erfindungsgemäße Vorrich tung erlaubt die Entnahme vergleichsweise gerin ger Blutmengen, so daß für den Patienten keine nennenswerten Schwächungen mehr auftreten. The Vorrich tung invention allows the removal comparatively clotting ger amounts of blood, so that arise for the patient, no significant weaknesses more. 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. Wei ter is crucial that the supplied anticoagulant is completely mixed with the entnom menen blood and can not spread in the body, which would delay the healing process result. 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. When the guide to the infusion serving inner catheter ends further out, the collected blood is attached to no infusion solution so that the solution Mes can be made completely unaffected. 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. An advantage is still to be considered that the removal of the blood can be done from a central vessel, so that the occurring defects in peripheral withdrawals Tenden complications and disorders are afraid not to be.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden nä her beschrieben. An embodiment of the invention is illustrated in the drawing and will be described below nä forth.

Sie zeigt in schematisch gehal tener Darstellung einen Schnitt in axialer Rich tung durch die erfindungsgemäße Kathetervorrich tung. It shows in schematic representation a supported tener section in the axial Rich processing by the inventive Kathetervorrich processing.

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

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. Is critical to the invention that within the second catheter (2), a third catheter (3) is arranged, whose proximal end is within the nerseits ends of the outer end of the second catheter (2). Der Raum zwischen dem dritten Katheter ( 3 ) und dem ersten Katheter ( 1 ) dient der Zufuhr einer gerinnungshemmenden Lösung. The space between the third catheter (3) and the first catheter (1) is used 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. The end of the second catheter (2) projects slightly beyond the end of the third catheter (3) out from and is additionally axially abgerun det at the end. Die beiden Katheter ( 2, 3 ) sind über einen Schraubmechanismus ( 4 ) an ihren Ansatzstücken ( 5, 6 ) miteinander verbunden. The two catheter (2, 3) are connected via a screw mechanism (4) at their end pieces (5, 6) joined together.
