Description
Die Erfindung betrifft ein Filter mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a filter with the features of Preamble of claim 1.
Derartige Filter, wie sie aus der DE 38 31 786 A1, der DE 33 33 461 A1, der EP 477 966 A1 und dem JP-Abstract C-460, 1989, Vol. 13, No. 431 bekannt sind, finden in vielfältiger Weise, insbesondere auch im medizinischen Bereich, Verwendung. Such filters, as described in DE 38 31 786 A1 DE 33 33 461 A1, EP 477 966 A1 and the JP abstract C-460, 1989, Vol. 13, No. 431 are found in in many ways, especially in medical Area, use.
Das zu reinigende Fluid tritt dabei über einen durch die Verschlußkappe gebildeten Raum in die offenen Stirnflä chen der Kapillaren der Hohlfasern ein. Das ungeleitete Fluid bildet in diesem Bereich Verwirbelungen, die den von dem Filter dem zu reinigenden Fluid entgegengebrach ten Strömungswiderstand erhöhen und Bestandteile des zu reinigenden Fluids schädigen können.The fluid to be cleaned passes through the Cap formed space in the open end face Chen the capillaries of the hollow fibers. The unguided Fluid forms eddies in this area, which the from the filter to the fluid to be cleaned increase flow resistance and components of the cleaning fluid can damage.
Der Erfindung liegt die Aufgabe zugrunde, das vorbekann te Filter dahingehend zu weiterzubilden, daß die Entste hung von Verwirbelungen in den Verschlußkappen weitge hend vermieden wird.The invention has for its object that previously te filter to further develop that the Entste swirling in the caps largely is avoided.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des einzigen Anspruchs gelöst. According to the invention, this object is achieved by the features of the only claim solved.
Die Erfindung wird im folgenden anhand einer Zeichnung erläutert. Dabei zeigt die einzige Figur eine Schnittan sicht durch ein derartig ausgebildetes Filter.The invention is described below with reference to a drawing explained. The only figure shows a section view through such a filter.
Das Filter besteht aus einem im wesentlichen rohrförmi gen Gehäuse 10, einer an der einen Stirnseite des Gehäu ses angeordneten Einlaß-Verschlußkappe 12 zum Einlassen des zu reinigenden Fluids, einer an der anderen Stirn seite des Gehäuses angeordneten Auslaß-Verschlußklappe 14, durch die das gereinigte Fluid wieder ausgelassen wird, einem von dem Gehäuse 10 aufgenommenen, von dem zu reinigenden Fluid durchströmten Hohlfaserbündel 16, einem seitlich an das Gehäuse angesetzten Einlaßstutzen 18 zum Zuführen eines die Fasern des Hohlfaserbündels 16 umströmenden Reinigungsfluids und einem seitlich an das Gehäuse angesetzten Auslaßstutzen 20 für das Reinigungs fluid.The filter consists of a substantially tubular housing 10 , one on one end of the hous ses arranged inlet cap 12 for admitting the fluid to be cleaned, one on the other end side of the housing arranged outlet flap 14 through which the cleaned Fluid is released again, a hollow fiber bundle 16 received by the housing 10 and through which the fluid to be cleaned flows, an inlet connection 18 attached laterally to the housing for supplying a cleaning fluid flowing around the fibers of the hollow fiber bundle 16, and an outlet connection 20 attached laterally to the housing for the Cleaning fluid.
Die Verschlußkappen 12, 14 sind mit einem Flanschab schnitt auf das Gehäuse 10 aufgesetzt.The caps 12 , 14 are cut with a flange section placed on the housing 10 .
Im Bereich der beiden äußeren Bereiche des Hohlfaserbün dels sind diese umfassende Klebeblöcke 24 angeordnet, die den von dem Reinungsfluid umströmten Raum von dem Bereich der Verschlußkappen 12, 14 hermetisch abschlie ßen.In the area of the two outer areas of the Hohlfaserbün dels these comprehensive adhesive blocks 24 are arranged, which hermetically seal the space around which the cleaning fluid flows from the area of the sealing caps 12 , 14 .
Im Bereich der Verschlußklappen 12 und 14 sind jeweils in einem nach innen durch die Klebeblöcke 24 und nach außen einerseits durch die Flanschabschnitte 22 der Verschluß kappen 12, 14 und andererseits durch das Gehäuse 10 be grenzte Bereiche Kompensationsringe 26 angeordnet. In the area of the flaps 12 and 14 are each in an inward through the adhesive blocks 24 and outwardly on the one hand through the flange portions 22 of the closure caps 12 , 14 and on the other hand through the housing 10 be limited areas compensation rings 26 are arranged.
Zwischen den Klebeblöcken 24 und den Verschlußkappen 12, 14 ist jeweils ein Dichtungsscheibenring 28 vorgesehen.A sealing disk ring 28 is provided between the adhesive blocks 24 and the sealing caps 12 , 14 .
Die Verschlußkappen 12, 14 sind sich von außen nach in nen trompetenförmig erweiternd ausgebildet, in den Ver schlußkappen 12, 14 ist jeweils ein Strömungsleitkörper 30 angeordnet, so daß in den Verschlußkappen 12, 14 jeweils ein trichterförmiger Ringraum gebildet ist, durch den das zu reinigende Fluid in den Filter einge führt bzw. aus dem Filter ausgeführt wird. Die Strö mungsleitkörper 30 wirken einer Bildung von Wirbeln in dem Raum, in dem das zu reinigende Fluid in die Hohlfa sern eintritt, entgegen, wodurch zum einen der Strö mungswiderstand des Filters reduziert und zum anderen die Bestandteile des zu reinigenden Fluids geschont wer den, was insbesondere dann von Bedeutung ist, wenn es sich dabei um eine Körperflüssigkeit handelt.The caps 12, 14 are themselves formed trumpet-shaped widening from the outside to NEN, final hats in the Ver 12, 14, a flow guide 30 is arranged in each case so that in each case a funnel-shaped annular space is formed in the end caps 12, 14, to be purified by the Fluid is introduced into the filter or is carried out of the filter. The flow guide body 30 counteract the formation of vortices in the space in which the fluid to be cleaned enters the hollow fibers, which on the one hand reduces the flow resistance of the filter and on the other hand protects the components of the fluid to be cleaned, which is what is particularly important if it is a body fluid.
Bei der Verwendung werden die Verschlußstopfen 36, 38 entfernt. Sodann wird ein geeignetes Schlauchsystem für das zu reinigende Fluid an die beiden Verschlußkappen 12, 14 angelegt. Das Fluid strömt sodann - von den Strö mungsleitkörpern 30 geeignet verteilt - durch das eine Membran darstellende Hohlfaserbündel 16.In use, the plugs 36 , 38 are removed. A suitable hose system for the fluid to be cleaned is then placed on the two caps 12 , 14 . The fluid then flows - appropriately distributed by the flow guide bodies 30 - through the hollow fiber bundle 16 which represents a membrane.
Ein Reinigungsfluid mit einer gegenüber dem zu reinigen den Fluid hohen Affinität wird über den Einlaßstutzen 18 in den Filter eingebracht und umströmt die als Membran wirkenden Fasern des Hohlfaserbündels 16 im Gegenstrom, um sodann durch den Auslaßstutzen 20 wieder abgeführt zu werden. A cleaning fluid with a high affinity for the fluid to be cleaned is introduced into the filter via the inlet connection 18 and flows around the fibers of the hollow fiber bundle 16 acting as a membrane in countercurrent, in order then to be discharged again through the outlet connection 20 .
Die Verschlußkappen 12, 14 können auf das Gehäuse aufge schraubt, aufgeschweißt, aufgeklebt, an diese ange spritzt oder aber an diese angeklippst sein.The caps 12 , 14 can be screwed onto the housing, welded, glued, injected onto this or clipped onto it.
