Nummer: 1236476
Aktenzeichen: D 37061IV a/12 d
Anmeldetag: 19. September 1961

Die Erfindung betrifft einen Dialysator, bestehend aus einem Behälter mit durch Trennwände abgeteilten
Flüssigkeitssammelräumen an beiden Enden, mit Rohranschlüssen für die Zu- und Abführung von
Dialysat und Dialysierflüssigkeit und mit einer Vielzahl im Behälter zwischen den Trennwänden angeordneter,
mit beiden Flüssigkeitssammelräumen in Verbindung stehender röhrenförmiger Dialysiermembranen
in gebündelter Form.
Die röhrenförmigen Membranen haben bei bekannten Vorrichtungen dieser Art einen verhältnismäßig
großen Durchmesser in der Größenordnung von ein Zehntel des Durchmessers des Behälters.
Demgegenüber sind ernndungsgemäß die röhrenförmigen Membranen von an sich bekannten feinen
Hohlfasern gebildet, und diese Hohlfasem sind zu einer Mehrzahl von Teilbündeln zusammengefaßt
und an ihren Enden mittels Teilbündelfassungen in Halterungen der Trennwände eingesetzt. Die feinen
Hohlfasern können als Nachbildung der in echten Nieren vorkommenden feinen Haargefäße aufgefaßt
werden.
Die Zusammenfassung der Hohlfasern zu einer Mehrzahl von Teilbündeln hat den Vorteil, daß diese
leichter montiert werden können als bei einer Ausführungsform, bei der jede Faser einzeln gehaltert
ist, und daß sie leichter ausgetauscht werden können als bei einer Ausführungsform, bei der sämtliche Fasern
ein einziges Bündel bilden.
Die Halterungen in den Trennwänden können von Bohrungen, welche die Teilbündelfassungen
unter Einschaltung von Dichtungen aufnehmen und von Verriegelungsgliedern gebildet sein,
welche die Teilbündelfassungen in den Bohrungen festhalten.
Die Teilbündelfassungen können an den Teilbündelenden
in der Weise befestigt werden, daß sie diese ringförmig umschließen und mit diesen verkittet
sind.
Die Teilbündel können einzeln oder zu mehreren in ihrer Längsrichtung spannbar sein.

(57055,57056),
vom 16. Juni 1961 (117 647)
Fig. 7 eine vergrößerte Teilansicht der Fassung, teilweise aufgebrochen.
In F i g. 1 wird die ganze Einrichtung mit 10 bezeichnet. Sie ist aufgebaut aus einem röhrenförmigen
Behälter 16, an dessen Enden Sammler 14 und 15 angesetzt sind. Der röhrenförmige Behälter 16 weist
eine Flüssigkeitszuleitung 11 und eine Flüssigkeitsableitung 12 für das der Osmosebehandlung zu unterwerfende
Strömungsmittel auf. Die Sammler 14 und besitzen Anschlüsse 13 für dasjenige Strömungsmittel,
welches durch die Osmosezellen hindurchgedrungen ist.
Die Osmosezellen sind als Teilbündel von feinen Hohlfasern ausgeführt. Die Bündel sind in den Figuren
"mit 19 bezeichnet, die einzelnen Fasern mit 20 (s. Fig. 4). Die Teilbündel 19 sind, wie aus Fig. 4
ersichtlich, mit ihren Enden 22 in Durchgänge 27 von
Teilbündelfassungen 25 eingekittet. Die Teilbündelfassungen 25 sind in Bohrungen 24 von Trennwänden
eingesetzt und in diesen Bohrungen 24 durch Dichtungen 26 abgedichtet. Festgehalten sind die
Teilbündelfassungen in axialer Richtung durch Ver-
riegelungsplatten 29 und 31 mit Fenstern 39. Die Fenster 39 können nach Lösen von Langlöcher 41
der Verriegelungsplatten 29, 31 durchsetzenden
709 519/354
Schraubenbolzen 38 zur Deckung mit den Bohrungen 24 gebracht werden, wodurch der Ein- und Ausbau
der Teilbündelfassungen 25 ermöglicht wird. Die Trennwände 17 sind, wie aus Fig. 1, rechte Hälfte,
ersichtlich, durch Zugbolzen 40 in ihrer axialen Lage einstellbar. Die Einstellung der Zugbolzen 40 ermöglicht
ein Spannen der Teilbündel 19.
Zum Einkitten der Bündel in die Teilbündelfassungen kann Epoxyharz verwendet werden.
Die erfindungsgemäße Vorrichtung kann beispielsweise
für folgende technische Zwecke eingesetzt werden: Zur Gewinnung von Süßwasser aus Seewasser;
zum Konzentrieren von Frucht- und Gemüsesäften und von entrahmter Milch; als künstliche Niere.
