Description

Die Erfindung betrifft ein aufklappbares Klemmstück mit einem Balgaufsatz zur Aufnahme eines Primärpackmittels in Form eines langgestreckten zylindrischen Röhrchens.The invention relates to a hinged clamping piece with a bellows attachment for receiving a primary packaging in the form of an elongated cylindrical tube.

Zur Verabreichung geringer Mengen von Arzneimittelflüssigkeiten bediente man sich bisher der Mikropipetten. Bei der Verwendung von Mikropipetten ist es notwendig, daß die Arzneimittelflüssigkeit in größeren Vorratsbehältern, die das Abfüllen der Mikropipetten gestatten, vorliegt. Arzneimittelflüssigkeiten, die sehr leicht kontaminieren oder die in ihrer Herstellung sehr teuer sind (z. B. Interferonlösungen) lassen sich so nicht bereitstellen; sie können also nicht z. B. mittels Mikropipetten verabreicht werden.Up to now, micropipettes have been used to administer small amounts of pharmaceutical liquids. When using micropipettes, it is necessary for the medicinal liquid to be present in larger storage containers which allow the micropipettes to be filled. Medicinal liquids that contaminate very easily or that are very expensive to produce (e.g. interferon solutions) cannot be provided in this way; so you can not z. B. administered by means of micropipettes.

Erfindungsgemäß läßt sich dieses Problem dadurch lösen, daß ein langgestrecktes Röhrchen, bespielsweise eine Kapillare, welches die Arzneimittelflüssigkeit enthält und an seinen beiden Enden verschlossen ist, in eine aufklappbare Haltevorrichtung, bestehend aus zwei Halbschalen, eingangs als aufklappbares Klemmstück bezeichnet, bündig mit den Innenwandungen dieser Haltevorrichtung eingelegt wird. Vor dem Zusammenklappen dieses Klemmstückes wird das Röhrchen an seiner, dem hinteren Ende des Klemmstückes zugekehrten Seite, unmittelbar vor der Applikation, geöffnet. Nach dem Zusammenklappen des Klemmstückes wird auf einen am hinteren Ende des Klemmstückes vorgesehenen Schaft ein Balg sattsitzend aufgeschoben; anschließend wird das andere, noch verschlossene Ende des Röhrchens geöffnet, wobei sich durch einen manuellen Druck auf den Balg das Füllgut aus dem Röhrchen entnehmen läßt, beispielsweise in Form einzelner Tropfen oder eines dünnen Strahls.According to the invention, this problem can be solved in that a Elongated tube, for example a capillary, which contains the medicinal liquid and is closed at both ends, in a hinged holding device, consisting of two half-shells, initially referred to as a hinged clamping piece, is inserted flush with the inner walls of this holding device. Before this clamping piece is folded up, the tube is opened on its side facing the rear end of the clamping piece, immediately before application. After the clamping piece has been folded together, a bellows is pushed onto the shaft provided at the rear end of the clamping piece; the other, still closed end of the tube is then opened, the contents being removed from the tube by manual pressure on the bellows, for example in the form of individual drops or a thin jet.

Das Klemmstück ist mit einer Halte- und Stützvorrichtung versehen, durch die es mittels zweier Finger jeweils soweit geöffnet werden kann, daß das einzulegende Röhrchen einwandfrei in die vorgesehene Lage gebracht werden kann. Beim Schließen des Klemmstückes zentriert sich das Röhrchen selbsttätig zwischen den beiden Halbschalen. Damit die Halbschalen das Röhrchen dauerhaft umschließen, wird eine Schließvorrichtung, z. B. eine Einrastvorrichtung, beispielsweise im Bereich der obengenannten Halte- und Stützvorrichtung, vorgesehen.The clamping piece is provided with a holding and supporting device by means of which it can be opened by means of two fingers to such an extent that the tube to be inserted can be brought into the intended position without problems. When the clamp is closed, the tube automatically centers between the two half-shells. So that the half-shells permanently enclose the tube, a closing device, for. B. a locking device, for example in the area of the above-mentioned holding and supporting device.

Das Klemmstück ist so konstruiert, daß das aufzunehmende Röhrchen beim Aufeinanderklappen und Zusammendrücken seiner beiden Halbschalen in der Halte- und Stützvorrichtung, die die beiden Halbschalen an einer geeigneten Stelle umgibt, zentriert eingebettet wird. Die Kalibrierung des Innendurchmessers des aus den beiden Halbschalen gebildeten Klemmstückes im zusammengeklappten und eingerasteten Zustand entspricht genau der Außenkontur des Röhrchens. Damit wird erreicht, daß das Röhrchen im Klemmstück fixiert ist, daß der Überdruck, der durch das Zusammendrücken des Balges entsteht und zum Ausdrücken der Flüssigkeit aus dem an den beiden Enden geöffneten Röhrchen führt, nicht auf Nebenwegen wirkungslos entweichen kann.The clamping piece is constructed in such a way that the tube to be accommodated is centered when the two half-shells are folded open and pressed together in the holding and supporting device which surrounds the two half-shells at a suitable point. The calibration of the inner diameter of the clamping piece formed from the two half-shells in the folded and locked state corresponds exactly to the outer contour of the tube. This ensures that the tube is fixed in the clamping piece so that the overpressure which arises from the compression of the bellows and leads to the squeezing out of the liquid from the tube opened at both ends cannot escape ineffectively on secondary paths.

Die mit den beiden Halbschalen fest verbundene Halte- und Stützvorrichtung entspricht den ergonomischen Anforderungen beim Einlegen des Röhrchens, beim Applizieren der Tropfen und bei der anwendungsbedingten Pause zwischen zwei Applikationen, in dem hierbei jeglicher Kontakt des Röhrchenendes mit anderen Gegenständen vermieden wird.The holding and support device, which is firmly connected to the two half-shells, corresponds to the ergonomic requirements when inserting the tube, when applying the drops and during the application-specific break between two applications by avoiding any contact of the tube end with other objects.

Als ein zum Ausdrücken der Tropfen aus dem Röhrchen erforderlicher Balg dient vorzugsweise ein Faltenbalg. Der Faltenbalgaufsatz besteht dabei aus einem zylindrischen Schaft, der in einem Faltenbalg mit einer oder mehreren Lamellen übergeht. Der Balgaufsatz wird nach dem Abtrennen des entsprechenden Röhrchenendes am hinteren Ende des Klemmstückes, nachdem dessen Halbschalen über dem Röhrchen zusammengeklappt und arretiert sind, an einem dafür vorgesehenen und entsprechend angepaßten Schaft sattsitzend aufgeschoben. Der Balg ist am hinteren Ende mit einer ausreichend großen öffnung versehen, die ein vorzeitiges Zustandekommen eines Über- oder Unterdruckes beim Aufschieben des Faltenbalgaufsatzes auf den Schaft verhindert.A bellows is preferably used as the bellows required to squeeze the drops out of the tube. The bellows attachment consists of a cylindrical shaft that merges into a bellows with one or more fins. After the corresponding end of the tube has been cut off, the bellows attachment is pushed onto the rear end of the clamping piece, after its half-shells have been folded and locked over the tube, on a specially provided and appropriately adapted shaft. The bellows is provided with a sufficiently large opening at the rear end that prevents premature overpressure or underpressure when the bellows attachment is pushed onto the shaft.

Die beiden Halbschalen des Klemmstückes sind durch ein Scharnier miteinander verbunden. Als Scharnier dient z. B. eine ausgedünnte Zone aus demselben Material, aus dem die Halbschalen gefertigt sind (bei-Kunststoffen ist dies spritztechnisch gesehen die beste Lösung), oder ein die beiden Halbschalen zusammenhaltender Film. Dieses Scharnier kann sich über die ganze Länge der Halbschalen erstrecken, es kann aber auch nur im Bereich der Halte- und Stützvorrichtung angebracht sein.The two half-shells of the clamping piece are connected to one another by a hinge. As a hinge z. B. a thinned zone of the same material from which the half-shells are made (for plastics this is the best solution from a spraying point of view), or a film holding the two half-shells together. This hinge can extend over the entire length of the half-shells, but it can also be attached only in the area of the holding and supporting device.

Durch einen Fingerdruck auf die Halte- und Stützvorrichtung werden die beiden Halbschalen soweit auseinander gespreizt, daß das Röhrchen einwandfrei eingelegt werden kann. Die problemlose Handhabung wird ermöglicht durch eine an der Scharnierseite in der Stütz- und Haltevorrichtung angebrachte Aussparung, die, in ihrer maßlichen Auslegung, auch als öffnungsanschlag dient.By pressing the holding and supporting device with a finger, the two half-shells are spread apart so far that the tube can be inserted properly. The problem-free handling is made possible by a recess on the hinge side in the support and holding device, which, in its dimensional design, also serves as an opening stop.

Nach dem Einlegen des Röhrchens werden durch eine Verlagerung des Fingerdruckes auf der Halte- und Stützvorrichtung in Richtung der offenen Kanten der Halbschalen die beiden Halbschalen geschlossen und mittels einer Einrast- bzw. Schnappvorrichtung oder einer anderen adäquaten Vorrichtung fest miteinander verbunden.After inserting the tube, the two half-shells are closed by shifting the finger pressure on the holding and supporting device in the direction of the open edges of the half-shells and firmly connected to one another by means of a snap-in or snap-on device or another suitable device.

Für eine Applikation wird zuerst das in Richtung Schaft zum Aufstecken des Balges zeigende Ende des Röhrchens entfernt; dies geschieht z. B. dadurch, daß die Röhrchenspitze an einer Sollbruchstelle abgebrochen oder daß sie mit einem Messer abgeschnitten oder mit einer Säge abgesägt wird. Anschließend wird über dieses offene Röhrchenende der Balgaufsatz geschoben und auf dem dafür vorgesehenen Schaft aufgesteckt. Erst dann wird das andere Ende des Röhrchens in analoger Weise entfernt. Die Kapillarkräfte verhindern, daß die Flüssigkeit auch beim senkrechten Halten der Applikationsvorrichtung noch vor der eigentlichen Applikation auslaufen kann.For an application, the end of the tube pointing towards the shaft for attaching the bellows is first removed; this happens e.g. B. by breaking the tube tip at a predetermined breaking point or by cutting it off with a knife or sawing it off with a saw. The bellows attachment is then pushed over this open tube end and attached to the shaft provided for this purpose. Only then is the other end of the tube removed in an analogous manner. The capillary forces prevent the liquid from leaking out even before the application is actually held when the application device is held vertically.

Zum Applizieren wird die Halte- bzw. Stützvorrichtung an dafür vorgesehenen Aussparungen zwischen dem Daumen und dem Mittelfinger gehalten. Die Zeigefingerkuppe wird auf die Stirnseite des Balges, z. B. eines Faltenbalges, gelegt, womit gleichzeitig die dort liegende Balgöffnung automatisch abgedeckt bzw. verschlossen wird. Durch ein leichtes, gleichmäßiges Niederdrücken des Balges in Richtung Halte- und Stützvorrichtung wird das Austropfen der Flüssigkeit aus dem Röhrchen ermöglicht.For application, the holding or supporting device is held at recesses provided between the thumb and the middle finger. The index finger tip is on the front of the bellows, for. B. a bellows, laid, whereby the bellows opening located there is automatically covered or closed. By gently and evenly pressing down the bellows in the direction of the holding and supporting device, the liquid can drip out of the tube.
