Description
Einmal-Versandspritze Gegenstand der Erfindung ist eine Einmal-Verandspritze zur Entnahme und zum Ve Versand von Untersuchungsmaterial meist in Form von Blut, Punktionsflüssigkeiten u. a. Disposable shipping syringe The subject of the invention is a disposable shipping syringe for taking and sending test material mostly in the form of blood, Puncture fluids, etc.
Diese Proben können nur selten von dem behandelnden Arzt selbst untersucht werden; sie werden daher einem entsprechenden Labor zugesandt. Hierzu verwendete man bisher Versandgefäße verschiedener Art, Form und Größe. Das Blut z.B. wird mit Hilfe einer Spritze entnommen und in die Versandgefäße gespritzt. Solche Spritzen finden außerdem im allgemeinen mehrfache Verwendung zur Injektion verschiedener Arzneimittel.These samples can only rarely be examined by the treating doctor himself will; they are therefore sent to an appropriate laboratory. Used for this so far, shipping containers of various types, shapes and sizes have been used. The blood, for example, is with With the help of a syringe and injected into the shipping containers. Such syringes also generally find multiple uses for injecting various Drug.
Trotz vermeintlich sorgfältiger Reinigung und Sterilisation können Spuren von Stoffen, die zwar bei erneuter Injektion von Arzneien keinen Schaden machen, das Untersuchungsergebnis des Blutes a,us solchen Spritzen aber verfälschen, wie besonders die Bestimmungswerte der Spurenelemente Calcium, Eisen, Jod usw. Außerdem besteht beim Ausspritzen des Blutes in das Versandgefäß die Gefahr der mechanischen Auflösung der roten Blutkörperchen, was die erforderliche Untersuchung dann ganz und gar unmöglich macht.Despite supposedly careful cleaning and sterilization Traces of substances that do not cause any damage when drugs are injected again make, but falsify the test result of the blood from such syringes, like especially the determination values of the trace elements calcium, iron, iodine etc. In addition there is a risk of mechanical damage when the blood is squirted into the shipping container Dissolution of the red blood cells, which then completely requires the examination and makes it impossible.
Aufgabe der Erfindung ist es, eine Spritze zu schaffen, die einerseits weder zu mehrfachen Injektionen nach Blutentnahmen verwendet werden kann, andererseits gleichzeitig als einmaliges Versandgefäß dient.The object of the invention is to create a syringe that on the one hand neither can be used for multiple injections after blood draws, on the other hand at the same time serves as a one-time shipping container.
Erfindungagemäß ist bei einer Einmal-Versandspritze zur Entnahme und zum Versand von Blut oder ähnlichen Proben der Schaft des Kolbens so elastisch ausgebildet, daß er nur zum Ziehen und nicht zum DrUcken des Kolbens verwendet werden kann, Die Spritze wird mit eingedrücktem Kolben angeliefert und dieser beim Aufziehen der Spritze an dem elastischen Schaft herausgezogen. Da der Schaft keinerlei Druckkraft aufnehmen kann, ist es nicht möglich, den Kolben wieder hineinzudrücken. Damit weist diese Spritze gegenüber den bekannten Spritzen den wesentlichen Vorteil auf, daß eine Wiederverwendung praktisch unmöglich ist.According to the invention, a disposable shipping syringe for removal and For the dispatch of blood or similar samples, the shaft of the piston is designed to be elastic, that it can only be used to pull and not to push the plunger The syringe is delivered with the plunger pressed in and this when the Syringe on the elastic Shaft pulled out. Since the shaft does not have any Can absorb compressive force, it is not possible to push the piston back in. This syringe thus has the essential advantage over the known syringes on that reuse is practically impossible.
Zweckmäßigerweise wird der elastische Schaft des Kolbens durch einen Kunststoffaden vorzugsweise aus Perlon gebildet. Der Faden kann bei aufgezogener Spritze leicht oberhalb des Kolbens in aufgewickeltem Zustand untergebracht werden.Appropriately, the elastic shaft of the piston is through a Plastic thread preferably made of Perlon. The thread can be pulled up The syringe can be placed slightly above the plunger in the coiled state.
Günstig ist es, als Griff an dem elastischen Kolben eine Platte zu befestigen, welche gleichzeitig das eine Ende der Spritze als Stopfen verschließen kann.It is advantageous to use a plate as a handle on the elastic piston fasten, which at the same time seal one end of the syringe as a stopper can.
Die mit der Spritze übersandten Proben werden zur Analyse meist zentrifugiert. Gemäß einer Weiterbildung der Erfindung wird daher die Einmal-Versandspritze mit einer abnehmbaren halbkugelförmigen Kappe ausgerüstet, die eine konische Öffnun zur Aufnahme des Spritzenkonus besitzt. Diese Kappe ermöglicht das unmittelbare Einsetzen der Spritze in die Zentrifuge und macht ein Umfüllen in ein anderes Zentrifugenröhrchen unnötig.The samples sent with the syringe are usually centrifuged for analysis. According to a further development of the invention, the disposable shipping syringe is therefore also included equipped with a removable hemispherical cap that has a conical opening for receiving the syringe cone. This cap enables the immediate Insert the syringe into the centrifuge and transfer it to another centrifuge tube unnecessary.
Die Erfindung wird an Hand der ein Ausführungsbeispiel zeigenden Abb. 1 näher beschrieben. Dabei rist in Abb. la eine erfindungsgemäße leere Spritze dargestellt, wie sie von der Herstellerfirma geliefert wird und in Abb. 1b eine aufgezogene versandfertige Spritze.The invention is illustrated by means of the Fig. 1 described in more detail. An empty syringe according to the invention is shown in Fig. La, as it is supplied by the manufacturing company and in Fig. 1b a mounted ready-to-ship Syringe.
Die Spritze besteht im wesentlichen aus einem Zylinder 1 aus Kunststoff, der in einen Konus 2 ausläuft, auf welchen die Kanüle aufgesteckt werden kann. Der Kolben D-ist ebenfalls aus Kunststoff und mit einer Gummidichtung 4 versehen. Der Kolbenschaft besteht aus einem Perlonseil 5, an dessen einem Ende ein Kunststoffstopfen 6 angebracht ist, der entsprechend Abb. 2a nach dem Aufziehen der Spritze als Verschluß dient.The syringe consists essentially of a cylinder 1 made of plastic, which ends in a cone 2, onto which the cannula can be attached. Of the Piston D is also made of plastic and has a rubber seal 4. Of the The piston skirt consists of a nylon rope 5 with a plastic stopper at one end 6 is attached, which according to Fig. 2a after pulling the syringe as a closure serves.
Um den Perlonfaden leichter unterbringen au können, ist der Kolben an seinem oberen Ende 7 abgerundet. Als Verschluß der Spritze nach Aufziehen des Blutes 8 und Entfernen der Kanüle dient die Kappe 9, die aus Gummi oder Kunststoff bestehen kann und so ausgebildet ist, daß sie einen halbkugelförmigen Abschluß der Spritze bildet. Diese kann damit unmittelbar als Zentrifugenröhrchen verwendet werden. Aus diesem Grund hat die Spritze bei aufgesetzter Kappe eine Länge von 96 mm, was der Länge eines Zentrifugenröhrchens entspricht.In order to be able to accommodate the nylon thread more easily, the Pistons rounded at its upper end 7. As a closure of the syringe after pulling up the For blood 8 and removing the cannula, the cap 9, which is made of rubber or plastic, is used can exist and is designed so that it has a hemispherical conclusion of the Syringe forms. This can then be used directly as a centrifuge tube. For this reason, the syringe has a length of 96 mm when the cap is on, what corresponds to the length of a centrifuge tube.
Der Kolben 3 hat eine Durchbohrung, durch welche eine Kanüle gesteckt und die Gummidichtung 4 durchstochen werden kann.The piston 3 has a through-hole through which a cannula is inserted and the rubber seal 4 can be pierced.
Auf diese Weise wird das völlige Herausziehen des Kolbens ohne Vakuumbildung in der Spritze ermöglicht.In this way, the piston is fully withdrawn without creating a vacuum in the syringe.
Die Erfindung ist nicht auf das beschriebene Ausführungsbeispiel beschränkt, sondern es können Änderungen getroffen werden, die im Rahmen des fachmännischen Könnens liegen, ohne daß damit der Schutzumfang der Erfindung überschritten wird0The invention is not restricted to the exemplary embodiment described, but changes can be made within the scope of the professional May be without thereby departing from the scope of the invention
