Abstract
Description
Die Erfindung betrifft eine Dialyse-Anordnung nach dem Oberbegriff des Anspruchs 1.The invention relates to a dialysis arrangement according to the preamble of claim 1.
Derartige Anordnungen sind in sogenannten Dialysezentren bekannt. Dabei besteht das Problem, dass die Abzweigleitungen, wenn dort kein Dialysegerät angeschlossen ist oder ein angeschlossenes Dialysegerät nicht betrieben wird, möglicherweise nicht durchströmt werden, was die Gefahr einer Verkeimung in sich birgt. Auch während einer Heißreinigung, bei welcher der Verteiler mit heißer Flüssigkeit durchgespült wird, ist wünschenswert, dass die Abzweigleitungen mitgereinigt werden.Such arrangements are in so-called dialysis centers known. The problem is that the branch lines if no dialysis machine there is connected or a connected dialysis machine is not may not be operated flows through become what the risk of contamination in them. Even during one Hot cleaning, where the distributor is flushed with hot liquid, is desirable that the branch lines are also cleaned.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Dialyse-Anordnung dahingehend zu verbessern, dass diese eine Durchströmung der Abzweigleitungen während einer Heißreinigung und auch während des Dialysebetriebes bei einem Verteiler mit nur einem einzigen Leitungsstrang sicherstellt.The invention has for its object a generic dialysis arrangement to improve in that this is a flow of the Branch lines during a hot cleaning and also during of dialysis operation with a distributor with only one Ensures wiring harness.
Diese Aufgabe wird durch eine Dialyse-Anordnung mit den Merkmalen des Anspruchs 1 gelöst.This task is accomplished through a dialysis arrangement solved with the features of claim 1.
Die Erfindung schlägt mit anderen Worten vor, definierte Strömungswiderstände zwischen zwei Abzweigleitungen im Verteiler vorzusehen. Auf diese Weise wird eine Durchströmung der Abzweigleitung erzwungen. Erfindungsgemäß wird dieser Strömungswiderstand durch ein federelastisches Ventil gebildet. Hierdurch ist sichergestellt, dass unabhängig von Druckschwankungen oder Geschwindigkeitsschwankungen der den Verteiler durchfließenden Strömung ein definierter Fluss durch die Abzweigleitung erfolgt.The invention beats with others Words before, defined flow resistances between provide two branch lines in the distributor. That way a flow the branch line enforced. According to the invention, this flow resistance formed by a spring-elastic valve. This ensures that regardless of pressure fluctuations or speed fluctuations of the Distributor flowing through defined flow through the branch line.
Das Ventil kann beispielsweise als Blattventil ausgestaltet sein, also einen in sich elastisch verformbaren Ventilkörper aufweisen, oder es kann alternativ hierzu einen Ventilkörper aufweisen – der gegebenenfalls in sich starr ausgestaltet ist – welcher federnd gelagert ist, beispielsweise ein trompetenförmiger oder auch als Tellerventil bezeichneter Ventilkörper, der durch eine Wendelfeder abgestützt ist.The valve can, for example, as Leaf valve be designed, that is an elastically deformable valve body have, or it may alternatively have a valve body - if necessary is rigid in itself - which is springy is stored, for example a trumpet-shaped or also as a poppet valve designated valve body, which is supported by a coil spring.
Sobald ausreichende Strömungsverhältnisse im Verteiler vorliegen, öffnet das erfindungsgemäß vorgesehene Ventil. Der bis dahin im Verteiler bewirkte Widerstand bewirkt jedoch eine zuverlässige Durchströmung der Abzweigleitung, die in Strömungsrichtung dem Ventil vorgelagert ist.As soon as sufficient flow conditions present in the distributor, opens that provided according to the invention Valve. However, the resistance brought about in the distributor up to that point a reliable flow through the Branch line in the direction of flow is upstream of the valve.
Mehrere derartige Ventile können im Verteiler hintereinander angeordnet sein. Gegebenenfalls kann in Strömungsrichtung des Verteilers gesehen, zwischen jeweils zwei zusammengehörigen Abzweigleitungen ein derartiges Ventil angeordnet sein, um durch seinen Strömungswiderstand bei Durchströmung des Verteilers zuvor eine Durchströmung des dem Ventil vorgelagerten Abzweigs sicherzustellen.Several such valves can Distributors can be arranged one behind the other. If necessary, in flow direction seen the distributor, between two associated branch lines such a valve can be arranged to by its flow resistance with flow of the distributor has a flow through that upstream of the valve Ensure branch.
Dabei kann aufgrund des sich über die Länge des Verteilers einstellenden Druckverlustes vorgesehen sein, dass in Strömungs richtung die Ventilstärke abnimmt, das heißt, dass eine zunehmend geringere Kraft erforderlich ist, um die Ventile zu öffnen.It can because of the Length of Distributor-setting pressure loss can be provided that in Flow direction the valve strength decreases, that is, that increasingly less force is required to power the valves to open.
Um nicht nur eine Durchströmung der Abzweigleitungen zu sichern, wenn ein daran angeschlossenes Dialysegerät nicht in Betrieb ist oder wenn an diese Abzweigleitung kein Dialysegerät angeschlossen ist, sondern um auch eine Heißreinigung der Dialyse-Anordnung zu ermöglichen, ist das erfindungsgemäß vorgeschlagene Ventil vorzugsweise für die bei der Heißreinigung auftretenden Temperaturen beständig. Je nach Ausgestaltung der Dialyse-Anordnung kann die Heißreinigung bei einem Temperaturniveau von unter 100° C erfolgen, oder bei einer dementsprechend druckbeständigen Ausgestaltung der Dialyse-Anordnung auch bei Temperaturen von oberhalb 100° C, z.B. bei etwa 130° Celsius.To not just a flow of the Secure branch lines if a dialysis machine is not connected is in operation or if no dialysis machine is connected to this branch line is, but also a hot cleaning to enable the dialysis arrangement is that proposed according to the invention Valve preferably for the hot cleaning occurring temperatures resistant. Depending on the design of the dialysis arrangement, the hot cleaning can at a temperature level below 100 ° C, or at a accordingly pressure-resistant Design of the dialysis arrangement even at temperatures from above 100 ° C, e.g. at about 130 ° Celsius.
Ein Ausführungsbeispiel der Erfindung wird anhand der rein schematischen Zeichnung nachfolgend näher erläutert. Dabei zeigtAn embodiment of the invention is explained in more detail below with the aid of the purely schematic drawing. there shows
