Abstract

The adapter is of a cylindrical shape with a slightly concave central area. The insertion areas at the outer ends are long enough for holding a short stretch of the cylindrical part of the syringes for stabilization. The insertion space continues in an asymmetrical shape towards the center in order to facilitate the joining of a syringe with the pointed part located off center. The central duct accommodated inside the concave segment can be fitted with rigid or flexible inner projections which can be permanently or removable attached.

Description

Die Erfindung betrifft einen Adapter für die sichere und stabile Verbindung zweier Spritzen ungleicher Bauart für die Zubereitung von mittels einer Spritze zu verabreichenden Mitteln, wie Diagnostika, Therapeutika und modifiziertes EigenblutThe The invention relates to an adapter for the secure and stable connection two syringes of unequal design for the preparation of means syringes, such as diagnostics, therapeutics and modified autologous blood

Zwei Spritze können so miteinander verbunden werden, so daß das Innere der ersten und zweiten Spritze über den Adapter miteinander kommunizieren.Two Syringe can be so interconnected, so that the interior of the first and second syringe over communicate with the adapter.

Im medizinischen Bereich ist es vielfach erforderlich, bei der Verabreichung von Diagnostika, wie z. B. Echokontrastmittel, und Therapeutika, wie z: B. Lyophilisate und bei der Eigenblut-Behandlung ene Homogenisierung der Mittel zu erreichen, homogene Suspensionen oder Emulsionen herzustellen oder bei Mitteln, wie Echokontrastmitteln, die oberflächenaktive Stoffe enthalten, die Bildung von Mikrobläschen zu fördern.in the medical field, it is often required in the administration of diagnostics, such as. Echo contrast agents, and therapeutics, such as, for example, lyophilisates and, in the case of autologous blood treatment, homogenization of the agents to achieve homogeneous suspensions or emulsions or for agents such as echo contrast agents containing surfactants, the formation of microbubbles to promote.

Aus der DE 4432993 C1 ist eine Mischeinrichtung für Spritzen bekannt, bei der ein Adapter zum Verbinden der beiden Spritzen eingesetzt wird, wobei der durchgehende Fließkanal des Adapters eine zentrale Mischkammer aufweist.From the DE 4432993 C1 a mixing device for syringes is known, in which an adapter for connecting the two syringes is used, wherein the continuous flow channel of the adapter has a central mixing chamber.

Auch die EP 0266 058 A2 zeigt eine Mischeinrichtung mit zwei Spritzen und einem die beiden Spritzen miteinander verbindenden Adapter, wobei der Fließkanal des Adapters einen konstanten Querschnitt aufweist. Diese Anordnung dient zum gleichmäßigen Vermischen eines pulvrigen Materials mit einem flüssigen Material zum Herstellen einer Kollagen-Mineral-KnochenreparaturAlso the EP 0266 058 A2 shows a mixing device with two syringes and an adapter connecting the two syringes with each other, wherein the flow channel of the adapter has a constant cross-section. This arrangement serves to uniformly mix a powdery material with a liquid material to produce a collagen mineral bone repair

Am Markt befindet sich ein einfacher hülsenförmiger Adapter, der in seiner Grundbestimmung darauf ausgelegt ist, medizinische Schläuche zu verbinden (Combidyn Adapter der Firma B. Braun Melsungen)At the Market is a simple sleeve-shaped adapter in his Basic provision is designed to medical tubing connect (Combidyn adapter from B. Braun Melsungen)

Aus der WO 92/11928 A1 ist eine Mischvorrichtung für Mikrobläschen-Echokontrastmittel bekannt, bei der eine Spritze mit einer Mischkammer unlösbar verbunden ist, die an ihren Innenwänden ebenfalls Mischelemente zur Umlenkung des durchströmenden Mediums aufweist und die mit einer Spritze, enthaltend das Medium, in dem die Mikrobläschen erzeugt werden sollen, verbunden wird, um durch Hin- und Herpumpen des Mediums durch die Mischkammer hindurch, die Mikrobläschen zu erzeugen. Das definierte Volumen der Mischkammer ermöglicht hierbei eine definierte Anzahl von Mikrobläschen zu erzeugen, wenn eine gleiche Agitationsleistung, d. h. hin- und herpumpen, vorliegt.Out WO 92/11928 A1 discloses a mixing device for microbubble echo contrast agents, in which a syringe is permanently connected to a mixing chamber, the their inner walls as well Having mixing elements for deflecting the medium flowing through and with a syringe containing the medium in which the microbubbles are generated be connected to by pumping the medium back and forth through the mixing chamber to produce the microbubbles. That defined Volume of the mixing chamber allows in this case to produce a defined number of microbubbles, if one same agitation power, d. H. pumping back and forth present.

Die bekannten Mischeinrichtungen gemäß DE 4432993 C1 , EP 0266 058 A2 und Combidyn Adapter erfüllen ihre Funktion dann sicher und zuverlässig, wenn gleichartige Spritzen verwendet werden und die Bewegung beim vielfachem Hin- und Herpumpen streng axial verläuft. Die Verwendung gleichartiger Spritze wird explizit empfohlen ( DE 4432993 C1 ). Werden beim Hin- und Herpumpen und bei großen Pumpdrücken die Spritzen nur leicht verkantet d.h. die Pumpbewegung wird nicht streng axial ausgeführt werden die Adapter undicht bzw. brechen. Es kann auch zum Bruch der Spritzen am Konus kommen. Die Combidyn Adapter sind für diese Belastung per se nicht ausgelegt, da sie nur zur statischen Vebindung vn Schläuchen vorgesehen sind. In der Medizin kommen Spritzen mit zentriertem Konus und Spritzen mit seitlich versetztem Konus zum Einsatz. Werden Spritzen unterschiedlicher Bauart mit dem Adapter verbunden, liegen die Kolbenachsen der zwei Spritzen zwangläufig nicht mehr in einer Achse und das Hin- und Herpumpen wird erschwert und die Zerstörung des Adapters ist vorprogrammiert, da das System in einer Verbiegung ausweicht.The known mixing devices according to DE 4432993 C1 . EP 0266 058 A2 and Combidyn adapters perform their function safely and reliably when similar syringes are used and the movement is strictly axial with multiple reciprocating pumping. The use of a similar syringe is explicitly recommended ( DE 4432993 C1 ). When pumping back and forth and at high pumping pressures, the syringes are only slightly tilted ie the pumping movement is not strictly carried out axially, the adapter leaking or breaking. It can also come to break the syringes on the cone. The Combidyn adapters are not designed for this load per se, as they are only intended for the static connection of hoses. In medicine, syringes with centered cone and syringes with laterally offset cone are used. If syringes of different types are connected to the adapter, the piston axes of the two syringes are inevitably no longer in one axis and the reciprocating pumping is made more difficult and the destruction of the adapter is preprogrammed, since the system evades in a bend.

Der Erfindung liegt die Aufgabe zugrunde, einen Adapter zu schaffen, der beim Einsatz von zwei Spritzen gleicher oder unterschiedlicher Bauart das sichere und effektive Einbringung von Energie zum Vermischen unterschiedlicher Medien ermöglicht. Der Adapter soll beim kräftiges Hin- und Herpumpen der Substanzen zwischen den Spritzen, die Spritzen stabilisieren und das Durchbrechen des System auf Höhe des Adapters und im Bereich des Spritzenkonus verhindern. Gleichzeitig soll diese Anforderung auch gelten wenn nicht gleiche Spritzentypen verwendet erden, sonder Spritzen unterschiedlicher Bauart.Of the Invention has for its object to provide an adapter the same or different when using two syringes Design the safe and effective introduction of energy for mixing different media possible. Of the Adapter should be strong Pumping the substances between the syringes, stabilizing the syringes and breaking the system at the level of the adapter and in the area prevent the syringe cone. At the same time, this requirement should also apply if the same syringe types are not used, but Syringes of different types.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein Adapter der eingangs angegebenen Art mit einer verbesserten Eigenschaften zu schaffen und damit die oben beschriebenen Nachteile zu eliminieren.From that Based on the object of the invention, an adapter of the type specified above with improved properties to create and thus eliminate the disadvantages described above.

Die technische Lösung ist gekennzeichnet durch die Merkmale im Anspruch 1.The technical solution is characterized by the features in claim 1.

Die Grundidee des erfindungsgemäßen Adapters besteht darin, daß nicht nur der Konus der Spritzen im Adapter fixiert ist, sondern auch ein Anteil des Spritzenzylinders vom Adapter teilweise umschlossen und damit stabilisiert wird. Die Bohrung im Adapter ist nicht wie zu erwarten rund sondern länglich. Dies ermöglicht die stabile Führung und Fixierung auf etwa die Hälfte des Umfanges des Spritzenkolbens beliebiger Bauart.The Basic idea of the adapter according to the invention is that not only the cone of the syringes is fixed in the adapter, but also a portion of the syringe barrel partially enclosed by the adapter and thus stabilized. The hole in the adapter is not like to be expected round but oblong. this makes possible the stable leadership and fixation to about half the size of the syringe plunger of any design.

Um die universelle Anwendbarkeit des erfindungsgemäßen Adapters und damit der Mischeinrichtung zu ermöglichen, wird vorgeschlagen, den Adapter so zugestalten, daß die jeweiligen Anschlüsse als Luer- Lock weiblich-weiblich oder Luer-Lock männlich-weiblich oder Luer-Lock männlich-männlich ausgebildet sind. Das heißt entweder sind die freien Enden beide als weibliche Anschlüsse, wie in dem gezeigten Beispiel oder ein Ende als männlicher Anschlug mit einem entsprechenden Außenkegel und das andere Ende als weiblicher Anschluß ausgebildet. Oder beide freien Ende sind als männliche Anschlüsse ausgebildet. Des weiteren ist bevorzugt, den Adapter im Anschlußbereich so auszubilden, daß er an handelsübliche Spritzen mit Luer-Lock-Kegel nach, DIN 13090, insbesondere für Spritzen der Größen 2 ml bis 50 ml montiert werden kann.Around the universal applicability of the adapter according to the invention and thus the To enable mixing device It is proposed to design the adapter so that the respective connections as Luer-Lock female-female or Luer-Lock male-female or Luer-Lock male-male are. This means either the free ends are both female connectors, like in the example shown or an end as a male contact with a corresponding outer cone and the other end is designed as a female connection. Or both free End are as male connections educated. Furthermore, it is preferred, the adapter in the connection area so that he to commercially available Spraying with Luer-Lock cone according to DIN 13090, especially for syringes the sizes 2 ml up to 50 ml can be mounted.

Ein nicht zu übersehender Vorteil der Erfindung ist dann zu sehen, daß der Adapter bei der Herstellung oder nachträglich mit Mischelementen versehen werden kann. Hierzu werden in den Fließkanal statische oder flexible Widerstände, Schikanen oder Blenden eingebracht.One not to be overlooked Advantage of the invention is then seen that the adapter in the manufacture or subsequently can be provided with mixing elements. For this purpose, in the flow channel static or flexible resistors, Baffles or apertures introduced.
