Vorrichtung zur Entnahme τοη Sterilproben * Device for taking τοη sterile samples *

Die Heuerung betrifft eine Vorrichtung sur Entnahme ve» Sterilproben eines durcL ein Leitungssystem strömenden steriles.The hiring relates to a device for taking sterile samples of a sterile flowing through a line system. Mediums.Medium.

Vorrichtungen zur Probeentnahme sind in verschiedenen Ausführungen bekannt. KLt diesen Vorrichtungen ist es jedoch nor unter einem erheblichen Aufwand möglich, Sterilproben eines sterilen Mediums beispielsweise einem Leitungsstrang zu entnehmen.Sampling devices are known in various designs. KLt, however, is not among these devices a considerable effort possible to obtain sterile samples of a sterile Medium, for example, to be taken from a cable harness.

Auch ist bei bekannten Sterilprobeentnahmegeräten vielfach eine Infektion gerade im Augenblick des Eingriffs in den Sterilraum durch Einstich einer infixest'.dn Sterilnadel von außen durch eine Verschiießmembrane lh das Sterilsystem gegeben. Darüber hinaus ist die Be-UiIgV1Hg derartiger Probeentnahmestellen mit erheblichen Schwier ' gkeiten verbunden.In the case of known sterile sampling devices, an infection is often given precisely at the moment of intervention in the sterile room by an infixest'.dn sterile needle piercing from the outside through a sealing membrane lh the sterile system. In addition, the Be-UiIgV 1 Hg of such sampling points is associated with considerable difficulties.

Aufgabe der Neuerung ist es, hier Abhilfe zu schaffen und eine insbesondere zur Entnahme von Sterilproben geeignete und einfache Vorrichtung zu schaffen.The task of the innovation is to remedy this situation and to create a simple device that is particularly suitable for taking sterile samples.

Diese Aufgabe wird gelöst durch ein im Leitungssystem angeordnetes Mehrwegeventil mit einem am verschließbaren Austrittsanschluß lösbar angeordneten Probe entnahme rohr, dessen Aufnahmekammer mittels zweier Einzelventile verschließbar ist.This object is achieved by a multi-way valve arranged in the line system with a sampling tube arranged releasably on the closable outlet connection, the receiving chamber of which can be closed by means of two individual valves.

Mit dieser Vorrichtung können unter Eingliederung eines luptrittsanschlusses an jeder beliebigen Stelle eines Leitungssystems Proben entnommen werden, ferner ist die Sterilisation der Vorrichtung durch Ableiten eines Teilstromes der chemischen Reinigungsflüssigkeit durch das Probeentnahmerohr auf einfache Weise möglich.With this device, samples can be taken at any point in a line system with the integration of a ventilating connection, and sterilization is also possible the device by diverting a partial flow of the chemical cleaning liquid through the sampling tube in a simple manner Way possible.

Gemäß einer Weiterbildung der Neuerung wird vorgeschlagen, daß das Mehrwegeventil unterhalb des Sitzes des den Austritt steuernden Schließventils einen Anschluß an ein Sterilisationssystem aufweist.According to a further development of the innovation, it is proposed that the multi-way valve be below the seat of the outlet controlling closing valve has a connection to a sterilization system.

Auf diese Weise ist es unabhängig vom Durchsatz des sterilen Mediums möglich, das Probeentnahmerohr mit allen Anschlußelementen einwandfrei zu sterilisieren.In this way it is independent of the throughput of the sterile one Medium possible, the sampling tube with all connection elements to sterilize properly.

Zum Aufbau des für die Sterilisationstemperatur erforderlichen Druckes wird ferner vorgeschlagen, daß an der dem Austrittsanschluß gegenüberliegenden Seite des Probeentnahmerohres eine Blende angeordnet ist.To build up the pressure required for the sterilization temperature, it is also proposed that on the side of the sampling tube opposite the outlet connection a Aperture is arranged.

Darüber hinaus wird durch die Anordnung einer Blende an dieser Stelle ein Kondensatstau und der damit verbundenr Temperaturabfall vermieden.In addition, the arrangement of a screen at this point creates a build-up of condensate and the associated drop in temperature avoided.

Schließlich hat es sich insbesondere z-ur Temperaturüberwachung als zweckmäßig erwiesen, in Höhe der Blende einen Temperaturfühler anzuordnen.Finally, it is particularly useful for temperature monitoring proven to be useful to arrange a temperature sensor at the level of the panel.

Die Neuerung und weiter mit ihr zusammenhängende Merkmale sind nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The innovation and further features associated with it are described below using an exemplary embodiment shown in the drawing explained in more detail.

Das sterile Medium fließt durch eine Leitung 1, welche ein Mehrwegeventil 2 aufweist. Am austrittsseitigen Anschluß 3 des Mehrwegeventils 2 ist ein Probeentnahmerohr 4 lösbar befestigt. Das Probeentnahmerohr 4 weist eine Aufnahmekammef 5 auf, welche mittels Einzelventile 6, 7 verschließbar ist. Unterhalb des Ventils 7 ist eine Blende 8 mit einem Staurohr 9 und einem darin eingegliederten Temperaturfühler 10 angeordnet.The sterile medium flows through a line 1, which is a multi-way valve 2 has. A sampling tube 4 is detachably attached to the outlet connection 3 of the multi-way valve 2. The Sampling tube 4 has a receiving chamber 5, which can be closed by means of individual valves 6, 7. Below the valve 7 is a diaphragm 8 with a pitot tube 9 and one therein integrated temperature sensor 10 arranged.

Das Probeentnahmerohr 5 wird vor Entnahme des sterilen Mediums durch Einleiten von Dampf durch die Leitung 12 bei geöffneten Einzelventilen 6 und 7 sterilisiert. Der für die Sterilisations temperatur erforderliche Druck baut sich oberhalb der Blende 8 auf. Die Überwachung der Sterilisation wird über den Temperatur fühler 10 vorgenommen, welcher bei Abfall der Temperatur eine Störmeldung signalisiert. Nach ausreichender Sterilisation des Probeentnahmerohres 4 und aller Anschlußelemente wird die Dampf zufuhr unterbrochen und das in der Leitung 1 angeordnete Mehrwegeventil 2 geöffnet.
