The invention relates to an implantable infusion pump with a housing in which a a steam pressure-generating propellant space and a drug receiving drug are trained, and with one with a cathete connecting choke element, the one with a plurality of through fine depressions in one Surface formed throttle sections provided base plate and has a cover plate placed on the base plate.
Eine derartige implantierbare Infusionspumpe ist aus der DE 195 15 722 C1 bekannt.Such an implantable infusion pump is out known from DE 195 15 722 C1.
Die Aufgabe besteht nun darin, die einzelnen Drossel strecken des Drosselelements zu- und abschalten zu kön nen, wobei die kompakte Anordnung beibehalten werden soll.The task now is to single choke stretch the throttle element on and off NEN, keeping the compact arrangement should.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Grundplatte mit in der Ebene der Grundplatte an geordneten Mikro-Ventilen versehen ist, die Abdeckplat te mit mit den Eingängen und den Ausgängen der Drossel strecken und den Ventilen kommunizierenden Bohrungen versehen ist und eine auf die Abdeckplatte aufgelegte Trägerplatte vorgesehen ist, die mit die Ein- und Aus gänge der Drosselstrecken und die Ventile miteinander verbindenden Kanälen versehen ist.According to the invention this object is achieved in that the base plate in the plane of the base plate orderly micro-valves is provided, the cover plate with the inputs and the outputs of the choke stretch and the valves communicating holes is provided and one placed on the cover plate Carrier plate is provided with the on and off gears of the throttle sections and the valves with each other connecting channels is provided.
Eine bevorzugte Ausführungsform zeichnet sich dadurch aus, daß die Grundplatte weiter in der Ebene der Dros selstrecke angeordnete Mikro-Drucksensoren aufweist, und die Trägerplatte mit von den Drucksensoren zu den Meßorten führenden weiteren Kanälen versehen ist.A preferred embodiment is characterized by this from that the base plate continues in the plane of the Dros micro-pressure sensors arranged in the line, and the carrier plate with from the pressure sensors to the Measuring channels leading further channels is provided.
Besonders bevorzugt ist eine Ausgestaltung, bei der die Drosselstrecken, die Ventile und ggf. die Drucksensoren als gesondert voneinander gefertigte und sodann in einer Ebene nebeneinander angeordnete Elemente ausge bildet sind.An embodiment is particularly preferred in which the Throttle sections, the valves and possibly the pressure sensors as separately manufactured and then in elements arranged next to each other on one level forms are.
Der vorgeschlagene Aufbau erlaubt es, ein Drosselele ment mit Drosselstrecken, Mikro-Ventilen und Drucksen soren zu schaffen, der kompakt ist und bei dem sich be züglich der Konnektierung der einzelnen Elemente keine Probleme stellen. The proposed structure allows a throttle element ment with throttling sections, micro-valves and pressure sockets to create sensors that are compact and that are easy to use none regarding the connection of the individual elements Pose problems.
Die Erfindung wird im folgenden anhand einer Zeichnung erläutert. Dabei zeigt:The invention is described below with reference to a drawing explained. It shows:

Fig. 4 eine Draufsicht auf die Grundplatte in Richtung der Pfeile C-C von Fig. 1. Fig. 4 is a plan view of the base plate in the direction of arrows CC in Fig. 1,.
Das Drosselelement besteht aus einer Grundplatte 10, die mit vier Drosselstrecken 20 versehen ist, wobei diese Drosselstrecken durch feine Vertiefungen in der Fläche der Grundplatte ausgebildet sind. Seitlich an die Drosselstrecken angrenzend sind vier in bekannter Weise von außen steuerbare Mikro-Ventile 22 angeordnet, in der in Fig. 4 unten rechts angeordneten Ecke sind zwei Mikro-Drucksensoren 28 vorgesehen. Die Drossel strecken 20, die Mikro-Ventile 22 und die Drucksensoren 28 sind dabei in einer Ebene angeordnet.The throttle element consists of a base plate 10 , which is provided with four throttle sections 20 , these throttle sections being formed by fine depressions in the surface of the base plate. Four micro-valves 22, which are controllable from the outside in a known manner, are arranged laterally adjacent to the throttle sections. Two micro-pressure sensors 28 are provided in the bottom right corner in FIG. 4. The throttle stretch 20 , the micro-valves 22 and the pressure sensors 28 are arranged in one plane.
Die Drosselstrecken 20, die Mikro-Ventile 22 und die Drucksensoren 28 sind in der Grundplatte 10 nicht mit einander kommunzierend verbunden. Sie können insbeson dere auch jeweils aus gesondert hergestellten Wavern herausgesägte, nebeneinander angeordnete Elemente sein. The throttle sections 20 , the micro-valves 22 and the pressure sensors 28 are not connected to one another in a communicating manner in the base plate 10 . In particular, they can also be sawn-out elements arranged next to one another from separately produced wafers.
Die Grundplatte 10 wird von einer Abdeckplatte 12 abge deckt (in Fig. 1 von unten), die mit Bohrungen 24 ver sehen, im übrigen aber hocheben ist. Die Bohrungen 24 kommunizieren mit den Eingängen und Ausgängen der Dros selstrecken 20, der Ventile 22 und der Drucksensoren 28. The base plate 10 is covered by a cover plate 12 (in Fig. 1 from below), which see ver with holes 24 , but is otherwise raised. The bores 24 communicate with the inputs and outputs of the throttle sections 20 , the valves 22 and the pressure sensors 28.
Auf der Abdeckplatte 12 wiederum liegt eine Trägerplat te 14 auf (in Fig. 1 von unten), die mit zu der Abdeck platte 12 hin offenen Kanälen 26, 30 versehen ist, wo bei diese Kanäle 26, 30 mit den Bohrungen 24 in der Ab deckplatte 12 kommunizieren, so daß die Kanäle 26, 30 die Ein- und Ausgänge der Drosselstrecke und der Venti le in geeigneter Weise miteinander verbinden sowie eine Kommunikation der Drucksensoren 28 mit den Meßorten be wirken.On the cover plate 12 in turn lies a Trägerplat te 14 (in Fig. 1 from below), which is provided with the cover plate 12 towards open channels 26 , 30 , where in these channels 26 , 30 with the holes 24 in the Ab cover plate 12 communicate, so that the channels 26 , 30 connect the inputs and outputs of the throttle section and the Venti le in a suitable manner and a communication of the pressure sensors 28 with the measuring locations be effective.
