Description

GEBIET DER VORLIEGENDEN ERFINDUNGFIELD OF THE PRESENT INVENTION

Die vorliegende Erfindung betrifft ein geschütztes Verschlusssystem für Laborröhrchen bzw. Pfropfenröhrchen, die in medizinischen Labors verwendet werden, z.B. zur Blutentnahme oder für die Behandlung von biologischen Flüssigkeiten.The present invention relates to a protected closure system for laboratory tubes grafted tubes used in medical laboratories, e.g. for blood collection or for the treatment of biological fluids.

BESCHREIBUNG DES STANDES DER TECHNIKDESCRIPTION OF THE PRIOR ART

Seit einiger Zeit sind sogenannte geschützte Verschlusssysteme für Laborröhrchen bekannt; diese Verschlusssysteme werden so genannt, weil sie mit einer Kappe bzw. mit einem Deckel ausgerüstet sind, die sowohl den Pfropfen als auch das obere Teil bzw. das obere Ende des Laborröhrchens schützen, d.h. das Teil des Laborröhrchens, in das der Pfropfen eingesetzt wird.For some time, so-called protected closure systems for laboratory tubes are known; these closure systems are so called because they are with a cap or with equipped with a lid which holds both the plug and the upper part or protect the top of the laboratory tube, i. the part of the laboratory tube into which the plug is inserted.

Im Wesentlichen enthält ein solches geschütztes Verschlusssystem zwei Teile, die formschlüssig miteinander gekuppelt sind:

  • einen inneren Körper aus Elastomer (der echte Pfropfen), der dazu dient, das Laborröhrchen zu verschließen und dazu geeignet ist, durchlöchert zu werden, um somit das Einsetzen der Nadel der Spritze ins Laborröhrchen zu ermöglichen; und
  • eine Kappe, die aus Kunststoffmaterial hergestellt und in entsprechender Weise starr ist.
    • Essentially, such a protected closure system contains two parts that are positively coupled with each other:
  • an elastomeric inner body (the true plug) which serves to seal the laboratory tube and is capable of being perforated to allow insertion of the needle of the syringe into the laboratory tube; and
  • a cap made of plastic material and correspondingly rigid.

    • Im Stand der Technik sind verschiedene geschützte Verschlusssysteme bekannt.Various proprietary closure systems are known in the art.

    Beispielsweise sei das geschützte Verschlusssystem genannt, das in der europäischen Patentschrift EP 0 129.029 beschrieben ist; bei diesem geschützten Verschlusssystem weist die Kappe auf der inneren dem inneren Körper gegenüberliegenden Oberfläche eine Rippe auf, in die eine entsprechende Rille eingesetzt wird, die sich aus dem oben genannten inneren Körper erstreckt.For example, the protected closure system mentioned in the European Patent EP 0 129,029 is described; in this protected closure system has the cap on the inner surface facing the inner body a rib into which a corresponding groove is inserted, resulting from the above extends said inner body.

    Sowohl das oben beschriebene geschützte Verschlusssystem als auch andere bekannte ähnliche Systeme haben den Nachteil, dass der Körper der Kappe Unterteile aufweist, die das Herstellen der Kappe durch Spritzgiessen äußerst kompliziert und schwierig machen.Both the protected closure system described above and other known ones similar systems have the disadvantage that the body of the cap has lower parts, Making the cap by injection molding extremely complicated and difficult do.

    Des Weiteren, weil Rippen auf der inneren Oberfläche des Deckels angebracht sind, muss die Wand des Deckels genügend dick sein; dies widerspricht aber der Voraussetzung, dass der Unterschied zwischen dem äußeren Durchmesser des Pfropfens und dem äußeren Durchmesser des Laborröhrchens so gering wie möglich sein muss, weil sonst das Laborröhrchen im geschlossenen Zustand, d.h. mit dem Verschlusssystem, nicht in Behälter oder andere Adapter von Labormaschinen eingesetzt werden kann.Furthermore, because ribs are mounted on the inner surface of the lid, the wall of the lid must be thick enough; but this contradicts the requirement that the difference between the outer diameter of the plug and the outer diameter of the laboratory tube must be as low as possible, because otherwise the laboratory tube in the closed state, i. with the locking system, can not be used in containers or other adapter of laboratory machines.

    Das europäische Patent EP 0 419 490 hat versucht, solche Nachteile zu überwinden, indem die Verkupplung zwischen den zwei Teilen des geschützten Verschlusssystems allein durch zwei Verlängerungen geschaffen wird, die sich aus der zylindrischen inneren Oberfläche der Kappe in Richtung der Längsachse erstrecken; diese Verlängerungen bilden eine Greifzone, die die Form einer Rippe bzw. eine Aussparung aufweist und dazu geeignet ist, eine ringförmige Rille aufzunehmen, die sich aus dem inneren Körper erstreckt, wobei die Verlängerung, die gegenüber dem Laborröhrchen liegt, sich zwischen dem Vorderteil des Laborröhrchens und der oben genannten ringförmigen Rille befindet. Diese Ausführungsform hat aber den Nachteil, dass das Teil des inneren Körpers, das in das Laborröhrchen eingesetzt wird (der echte Pfropfen) eine reduzierte Länge aufweist; weil aber die Länge des Pfropfens von der Länge der Nadel der Spritze vorbestimmt ist, wird die Reibungskraft zwischen Pfropfen und Laborröhrchen auch minimiert.European patent EP 0 419 490 has attempted to overcome such disadvantages by the coupling between the two parts of the protected closure system created solely by two extensions, resulting from the cylindrical inner Extend surface of the cap in the direction of the longitudinal axis; these extensions form a gripping zone, which has the shape of a rib or a recess and is adapted to receive an annular groove extending from the inner body extends, with the extension, which is opposite the laboratory tube, between the front part of the laboratory tube and the above-mentioned annular groove located. However, this embodiment has the disadvantage that the part of the inner body, which is inserted into the laboratory tube (the real stopper) a reduced Has length; but because the length of the plug depends on the length of the needle of the syringe is predetermined, the frictional force between grafting and laboratory tubes is also minimized.

    Ziel der Erfindung ist es, die oben genannten Probleme zu überwinden.The aim of the invention is to overcome the above-mentioned problems.

    Insbesondere ist ein Ziel der Erfindung, ein geschütztes Verschlusssystem für Laborröhrchen zu schaffen, das aus zwei einzelnen Teilen besteht, nämlich einen inneren Körper (der Pfropfen) aus Elastomer und einen äußeren Körper (die Kappe) aus Kunststoff, wobei die äußere Wand dieses zweiten Körpers so dünn wie möglich sein soll, so dass der Unterschied zwischen dem äußeren Durchmesser des zweiten Körpers und dem Durchmesser des Laborröhrchens so gering wie möglich ist.In particular, an object of the invention is a protected closure system for laboratory tubes to create, which consists of two separate parts, namely an inner Body (the plug) of elastomer and an outer body (the cap) of plastic, the outer wall of this second body being as thin as possible, so that the difference between the outer diameter of the second body and the diameter of the laboratory tube is as low as possible.

    Ein weiteres Ziel der vorliegenden Erfindung ist es, ein geschütztes Verschlusssystem zu schaffen, wobei die Kappe durch Spritzgiessen hergestellt werden kann und wobei ganz einfache Spritzgussformen verwendet werden können, so dass die Herstellungskosten niedriger sind als die Herstellungskosten von bekannten geschützten Verschlusssystemen.Another object of the present invention is to provide a proprietary closure system to provide, wherein the cap can be produced by injection molding and wherein quite simple injection molds can be used, so that the manufacturing cost lower than the manufacturing costs of known protected closure systems.

    Ein noch weiteres Ziel der vorliegenden Erfindung ist es, ein geschütztes Verschlusssystem zu schaffen, wobei der Zusammenbau der zwei Teile, d.h. das Aufsetzen der Kappe auf den inneren Körper schnell und zuverlässig ist.Yet another object of the present invention is to provide a proprietary closure system whereby the assembly of the two parts, i. putting on the Cap on the inner body is fast and reliable.

    Ein weiteres Ziel der vorliegenden Erfindung ist es, ein geschütztes Verschlusssystem zu schaffen, bei dem die Kappe immer in Berührung mit dem äußeren oberen Teil des Laborröhrchens ist, so dass die Verkupplung des Verschlusssystems mit dem Laborröhrchen verbessert wird, ohne dass zu diesem Zweck Schrauben oder Haken verwendet werden müssen.Another object of the present invention is to provide a proprietary closure system in which the cap is always in contact with the outer upper part of the cap Laboratory tube is, allowing the coupling of the closure system with the laboratory tube is improved without using screws or hooks for this purpose Need to become.

Die Kappe 6 weist auf ihrer oberen Schließwand 7 eine mittlere Öffnung 8 auf, um das Einführen der Entnahmenadel zu ermöglichen und besitzt eine zylindrische Wand 9, die den Pfropfen und den oberen Abschnitt des Laborröhrchens umschließt.Furthermore, the closure system has a cap 6 which is substantially cylindrical and is made of a compact plastic; this cap 6 serves to the inner Body 3 and the upper part of the laboratory tube record (see Fig. 1). The Cap 6 has on its upper closing wall 7 a central opening 8 to the insertion to enable the sampling needle and has a cylindrical wall 9, the encloses the plug and the upper section of the laboratory tube.

    Gemäß der vorliegenden Erfindung erstrecken sich aus der zylindrischen Wand 9 in radialer Richtung einige Vorsprünge 11, die in Berührung mit der äußeren Oberfläche 12 des Laborröhrchens 2 kommen und gegen diese äußere Oberfläche 12 einen Druck ausüben, um die Verkupplung des Verschlusssystems mit dem Laborröhrchen zu ermöglichen.According to the present invention extend from the cylindrical wall 9 in radial direction some projections 11 which are in contact with the outer surface 12th of the laboratory tube 2 come and against this outer surface 12 a pressure exercise to allow coupling of the closure system to the laboratory tube.

    Wie in Fig. 1 gezeigt, erstrecken sich die Vorsprünge 11 bis zu einer Entfernung "X" von der oberen Wand 7 der Kappe 6 aus, wobei diese Entfernung größer ist als die Höhe "Y" des Rings 5 des inneren Körpers. Somit wird eine Abstützstufe des Rings dargestellt und wird dadurch gewährleistet, dass in geschlossenem Zustand, die Kappe gegen das obere Teil des Laborröhrchens festgehalten wird.As shown in Fig. 1, the projections 11 extend to a distance "X" from the upper wall 7 of the cap 6, this distance being greater than the height "Y" of the ring 5 of the inner body. Thus, a support stage of the ring is shown and is thereby ensured that in the closed state, the cap against the upper part of the laboratory tube is held.

    Wie in Fig. 2 gezeigt ist, sind die Vorsprünge 11 in Übereinstimmung mit Öffnungen 13 angeordnet, die in der oberen Wand 7 der Kappe 6 angebracht sind, wobei der Querschnitt der Vorsprünge 11 innerhalb der Fläche dieser Öffnung 13 enthalten ist.As shown in FIG. 2, the projections 11 are in correspondence with openings 13 arranged, which are mounted in the upper wall 7 of the cap 6, wherein the cross section the protrusions 11 is contained within the area of this opening 13.

    Schließlich, wie in Fig. 3 und in den anderen Figuren gezeigt ist, können die Vorsprünge 11 verschiedene Formen aufweisen; zum Beispiel können langförmige Vorsprünge 11 in Richtung der Längsachse des Laborröhrchens orientiert sein und einen quadratischen oder dreieckigen Querschnitt aufweisen (Fig. 3).Finally, as shown in Fig. 3 and in the other figures, the projections Have 11 different shapes; For example, long-shaped projections 11 in Oriented towards the longitudinal axis of the laboratory tube and a square or triangular cross section (Fig. 3).

    Des Weiteren können die in Längsrichtung orientierten Vorsprünge durch eckige Vorsprünge 14 verbunden sein (Fig. 4) oder die Vorsprünge können eine kurvenförmige Ausdehnung aufweisen (Fig. 8). Die Vorsprünge können auch aus einer Vielzahl von Elementen 11.4 bestehen, die punktförmig bzw. noppenförmig sind (Fig. 7) oder die Vorsprünge können Winkelsegmente 11.5 sein, die quer zur Längsachse des Laborröhrchens liegen (Fig. 6).Furthermore, the longitudinally oriented projections can by angular projections 14 may be connected (FIG. 4) or the projections may be curved Have expansion (Fig. 8).
