Description
Claims (26)
ein Kunststoffgehäuse mit voneinander beabstandeten Front- und Rückwänden und einer zwischen den Front- und Rückwänden an einer Seite zur teilweisen Begrenzung einer ersten Flüs sigkeitsströmungskammer befindlichen Seitenwand, wobei das Gehäuse mit einem ersten Kammereinlaß in die erste Kammer und einem in die Seitenwand eingeformten ersten Kammeraus laß aus der ersten Kammer versehen ist;
einen ersten flexiblen Schlauch, der Flüssigkeit von der er sten Kammer zum Übertragungsgerät führt, wobei der erste Schlauch einen Teil einer für die Einwirkung der Rolle der Schlauchpumpe geeigneten Schleife bildet, ein Ende des er sten Schlauches mit dem Auslaß der ersten Kammer verbunden und ein anderer Teil der Schleife am Gehäuse derart befestigt ist, so daß die Schleife symmetrisch ist bezüglich einer senk recht zur Seitenwand verlaufenden Achse und die Schleifen achse im auf der Einrichtung angebrachten Zustand durch die Pumpenachse verläuft, und
eine Befestigungsvorrichtung zur Befestigung des Gehäuses auf der Einrichtung in zwei Stellungen, in einer ersten Stellung, bei der die Rückwand zur Einrichtung hin gerich tet ist, und einer zweiten Stellung, bei der die Frontwand zur Einrichtung hin gerichtet ist, wobei sich Teile der Schleife auf entgegengesetzten Seiten der Schleifenachse befinden, wenn das Gehäuse aus der ersten Stellung in die zweite Stellung gebracht wird.
Bereitstellung eines Flüssigkeitsübertragungsgerätes, einer arteriellen Kammer und einer venösen Kammer, wobei ein Einlaß des Flüssigkeitsübertragungsgerätes mit einem Auslaß der arteriellen Kammer verbunden ist, ein Auslaß des Flüssigkeitsübertragungsgerätes niedriger angebracht ist als der Einlaß des Flüssigkeitsübertragungsgerätes und mit einem Einlaß der venösen Kammer verbunden ist, die arterielle Kammer über einen in die arterielle Kammer an einer Stelle oberhalb des Auslasses der arteriellen Kammer eintretenden Einlaß verfügt und der Einlaß der ve nösen Kammer in die venöse Kammer an einer oberhalb des Auslasses der venösen Kammer liegenden Stelle eintritt, und
Betriebsvorbereitung des Blutströmungsweges der Einrich tung durch das Pumpen steriler Vorbereitungslösung durch die venöse Kammer, das Flüssigkeitsübertragungsgerät und die arterielle Kammer in gegenüber dem Normalbetrieb der Einrichtung umgekehrter Richtung, nämlich in den Auslaß der venösen Kammer, wobei die sterile Lösung in der venö sen Kammer bis zur Höhe des Eintrittes des Einlasses der venösen Kammer ansteigt, aufwärts durch das Flüssigkeits übertragungsgerät strömt, wobei darin befindliche Luftein schlüsse entfernt werden, und in die arterielle Kammer, wobei sie in der arteriellen Kammer bis zur Höhe des Ein trittes des Einlasses der arteriellen Kammer ansteigt, und wobei die Anfangsflüssigkeitsstände und Luftmengen in den arteriellen und venösen Kammern selbsttätig in vorgesehenen Höhen bzw. Mengen fixiert werden.
eine erste Kammer mit einem Einlaß und einem Auslaß zur Durchströmung der Kammer mit Flüssigkeit und einer star ren Kammerwand mit einer diese durchdringenden Öffnung,
eine impermeable, flexible Membran, die diese Öffnung ab dichtend bedeckt,
eine eine zweite Kammer begrenzende Einrichtung, die mit der Membran auf der der Kammer mit der starren Wand gegen überliegenden Seite der Membran mit dieser dicht verbunden ist, und
einem mit der zweiten Kammer kommunizierend verbundenen Druckmeßwertgeber, um den Druck in der Kammer zu messen,
wobei Druckänderungen in der ersten Kammer eine Verschie bung der Membran und dadurch des Volumens und des Druckes in der zweiten Kammer bewirken.
