While the hoses are on Attach the connecting pieces, the capillary tubes require special Connection elements through which e.g. a bond or jamming with the connection object.
Das Fluid strömt im Anschlussbereich und im anschlussnahen Teil der Schlauch- bzw. Kapillarverbindung in ein und derselben Richtung. Entsprechend groß ist der für den Verbinder erforderliche Platzbedarf. Durch die hohe Flexibilität der Schläuche bzw. Kapillarröhrchen kommt es leicht zu Verschlingungen. Die Verbindungsanordnung wird unübersichtlich.The Fluid flows in the connection area and in the connection near part of the hose or Capillary connection in one and the same direction. Accordingly large is the for the Connector required space. Due to the high flexibility of the hoses or capillary it comes easily to entanglements. The connection arrangement becomes confusing.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen neuen Verbinder zu schaffen, der den auf dem Gebiet der Mikrofluidtechnik erforderlichen Anforderun gen, insbesondere im Hinblick auf die Geometrie der Verbindungsanordnungen, besser gerecht wird.Of the present invention has for its object, a new connector to those required in the field of microfluidic technology Requirements, in particular with regard to the geometry of the connection arrangements, does better.
Der diese Aufgabe lösende Verbinder nach der Erfindung ist dadurch gekennzeichnet, dass das Übertragungselement einen flachen Körper mit in Richtung seiner Dickenausdehnung geringerer Biegesteifigkeit als in dazu senkrechten Richtungen umfasst.Of the solving this task Connector according to the invention is characterized in that the transmission element a flat body with in the direction of its thickness expansion lower flexural rigidity as in perpendicular directions.
Vorteilhaft erlaubt ein solcher, in seiner Flexibilität eingeschränkter Verbinder nach der Erfindung eine übersichtliche Verlegung von Verbindungen, wobei der flache Körper in vorteilhafter Ausgestaltung der Erfindung mehrere Verbindungskanäle aufweisen kann. Vorzugsweise sind die Kanäle zueinander im Abstand angeordnet, so dass Platz für Anschlusselemente geschaffen ist.Advantageous allows such a limited flexibility in its connector according to the invention a clear Laying of connections, wherein the flat body in an advantageous embodiment of the Invention multiple connection channels can have. Preferably, the channels are spaced from one another, leaving room for Connection elements is created.
Bei dem flachen Körper kann es sich um eine extrudierfe Folie handeln, in der wenigstens ein Verbindungskanal gebildet ist. Alternativ können mehrere Schläuche oder Kapillarröhrchen längsseitig unter Bildung eines Flachbands miteinander verbunden sein.at the flat body it may be an extruded film in which at least a connecting channel is formed. Alternatively, several hoses or capillary longitudinally be connected together to form a flat band.
In einer besonders bevorzugten Ausführungsform der Erfindung besteht der flache Körper aus einem Laminat aus wenigstens zwei Folien, zwischen denen der Verbindungskanalgebildet ist. Wie eine einzelne Folie kann auch ein solches, aus dünnen Folien gebildetes Laminat flexibel und in verschiedenen Biegeformen verlegbar sein.In a particularly preferred embodiment According to the invention, the flat body is made of a laminate at least two foils, between which the connecting channel is formed is. Like a single film can also be such, made of thin films formed laminate flexible and can be laid in different bending forms be.
Der Verbindungskanal ist zweckmäßig durch eine Rille in einer der Folien oder durch einander gegenüberliegende Rillen in beiden Folien gebildet, wobei sich die Rillen z.B. durch Prägetechniken erzeugen lassen.Of the Connecting channel is appropriate by a Groove in one of the foils or by opposing one another Grooves are formed in both films, the grooves e.g. by embossing techniques let generate.
Alternativ kann eine Zwischenfolie mit einer Schlitzöffnung gebildet sein, wobei der Kanal durch die beiden, die Schlitzöffnung abdeckenden Folien begrenzt ist.alternative an intermediate foil may be formed with a slot opening, wherein the channel bounded by the two, the slot opening covering films is.
Während es denkbar ist, Öffnungen des Verbindungskanals an den schmalen Randflächen der Folie bzw. des Laminats vorzusehen und in zu verbindenden Objekten Steckschlitze für die Folie bzw. das Laminat zu bilden, endet in der bevorzugten Ausführungsform der Erfindung der Verbindungskanal im Abstand vom Rand des durch die Folie bzw. das Laminat gebildeten flachen Körpers, und durch Löcher in der Folie, in einer der beiden Folien oder in beiden Folien des Laminats ist der Verbindungs kanal seitlich geöffnet. Dabei kann an den seitlichen Öffnungen des Verbindungskanals bzw. den Löchern am Laminat jeweils ein Anschlusselement vorgesehen sein. Ein zu dem Loch bzw. der Kanalöffnung ausgerichteter Durchgang des Anschlusselements steht senkrecht oder im Winkel zu dem Verbindungskanal bzw. der Laminatebene. Das Fluid wird an der Anschlussstelle umgelenkt, was platzsparende Verbindungen ermöglicht.While it is conceivable, openings of the connecting channel on the narrow edge surfaces of the film or the laminate provide and in the objects to be connected slits for the film or forming the laminate ends in the preferred embodiment the invention of the connecting channel at a distance from the edge of the film or laminate formed flat body, and through holes in the film, in one of the two films or in both films of the Laminate is the connection channel opened laterally. It can at the lateral openings of the Connecting channel or the holes be provided on the laminate in each case a connection element. One too the hole or the channel opening aligned passage of the connecting element is vertical or at an angle to the connecting channel or the laminate plane. The fluid is redirected at the connection point, which allows space-saving connections.
