Description

Injektionsspritze Die Erfindung betrifft eine Injektionsspritze mit einem in einem Spritzenzylinder axiel verschieblichen Kolben und einer mit dem Kolben lösbar verbindbaren Kolbenstange. Injection syringe The invention relates to an injection syringe with a plunger axially displaceable in a syringe cylinder and one with the plunger releasably connectable piston rod.

Eine derartige Spritze ist beispielsweise in der Auslegeschrift 2 024 117 gezeigt und beschrieben. Derartige Spritzen eignen sich insbesondere such zur Entnahme von Blutproben, wobei der Spritzonzylinder nach Abnahme der Kolbenstange vom Kolben als Versandgefäß benutzt werden kann.Such a syringe is, for example, in Ausleschrift 2 024 117 shown and described. Such syringes are particularly suitable for taking blood samples, the injection cylinder after removing the piston rod can be used by the flask as a shipping container.

Weiterhin eignen sich die Spritzenzylinder bei entsprechender Gestaltung als Zentrifugengefäß, wobei bei entaprechender Durchmesserabstufung die größeren Spritzenzylinder als Adapter für die kleinerer Zpritzenzylinder dienen können, um so alle Spritzenzylinder als Zentrifugengefäß in einer im Durchmesser genormten Zentrifugenaufnahme verwenden zu können.Furthermore, the syringe cylinders are suitable if they are designed accordingly as a centrifuge vessel, the larger with the corresponding diameter graduation Syringe cylinder can serve as an adapter for the smaller syringe cylinder to so all syringe cylinders as a centrifuge vessel in a standardized diameter To be able to use centrifuge holder.

kenn nun erwänncht sein, von einem größeren Probenvolukann nun erwünscht sein, aus einer großvolumigen Spritze mehrere kleinere Mengen für unterschiedliche Untersuchungen abzugeben, was bisher nur in der Weise geschehen kann, daß man aus der großen Spritze kleinere mengen entweder über die Spritztülle oder am anderen Ende nach Entfernung des Kolbens offen abgibt, was insbesondere bei infizierten Proben unerwtinacht sein kann.can now be asked for a larger sample volume well It may be desirable to obtain several smaller quantities for different quantities from a large-volume syringe To submit investigations, which so far can only be done in such a way that one can get out the large syringe smaller amounts either via the nozzle or on the other End after removal of the piston releases openly, which is especially true for infected people Rehearsals can be unexpected.

Der Erfindung liegt die Aufgabe zugrunde, Spritzen der eingangs geschilderten Art so auszugestalten, daß jedezeit der Inhalt einer Spritze ganz oder teilweise in ein anderes, mit einer Hohlnadel versehenes Gefäß, insbesondere eine andere Injektionsspritze wagefuilt werden kann, ohne daß der Spritzeninhalt mit der Umgebung in Kontakt kommt.The invention is based on the object of providing syringes of the initially described Kind of such a way that at all times the contents of a syringe wholly or partially into another vessel provided with a hollow needle, in particular another injection syringe can be wagefuilt without the contents of the syringe coming into contact with the environment.

Zur Lösung dieser Aufgabe wird vorgeschlagen, daß der Kolben mit einem den Durchtritt einer Hohlnadel gestattenden axialen kanal versehen ist, der durch einen Verschluß aus Silikongummi oder einem entsprechenden, nach Entfernung der Nadel einen dichten Abschluß gewährleistenden Material, verschlossen ist.To solve this problem it is proposed that the piston with a the passage of a hollow needle is provided permitting axial channel through a closure made of silicone rubber or a corresponding one, after removal of the Needle a tight seal ensuring material, is closed.

Vorzugsweise befindet sich der Verschluß auf der von der Kolbenstange abgewandten Seite des Kolbens.The closure is preferably located on that of the piston rod remote side of the piston.

Eine weitere zweckmäßige Ausgestaltung ist es, daß der Kanal auf der der Kolbenstange abgewandten Stirnseite des Kolbens mit einer Ansenkung zur Aufnahme des Verschlusses versehen ist.Another advantageous embodiment is that the channel on the the piston rod facing away from the end face of the piston with a countersink for receiving the closure is provided.

Anhand der nun folgenden 3eschreibung der Erfindung wird diese näher erläutert.This will be explained in more detail on the basis of the description of the invention that now follows explained.

Es zeigt: Fig. 1 eine erfindungsgemäß ausgestattete Injektionsspritze in schematischer Darstellung, Fig. 2 einen Axialschnitt durch einen in der Spritze zu verwendenden erfindungsgemäßen Kolgen.It shows: FIG. 1 an injection syringe equipped according to the invention in a schematic representation, FIG. 2 an axial section through one in the syringe to be used Kolgen according to the invention.

Die in Fig. 1 gezeigte Spritze besteht aus einem Spritzenzylinder 10 einem in diesem verschiebbaren Kolben 12, einer dem Kolben zugeordneten Kolbenstange 14 und einem in der Kolbenstange beweglichen Stellglied 16.The syringe shown in Fig. 1 consists of a syringe cylinder 10 a piston 12 displaceable in this, a piston rod assigned to the piston 14 and an actuator 16 movable in the piston rod.

Der Kolben 12 ist mit einem pil"frmigen Ansatz 18 versehen, der von durch Axialsohlitze am ihm zugewandten Ende der Kolbenstange 14 ausgebildeten federnden Zungen umgriffen werden kann. An ihrer Innenseite besitzen die Zungen 20 mit axialem Abstand zwei Nocken 22 und 24, zwischen die eine Durchmessererweiterung 26 am Stirnende des Stellgliedes 16 eindrtickbar ist. Wird das Stellglied weiter in axialer Richtung gegen den Kolben 12 gedruckt, so driickt os die Nockan 24 nach außen und spreizt damit die Zungen 20, so daß die Kolbenstange 14 vom Kolben 12 geldat werden kann.The piston 12 is provided with a pil "-shaped extension 18, which is of resilient formed by Axialsohlitze at the end of the piston rod 14 facing it Tongues can be grasped. On their inside, the tongues 20 have an axial Distance between two cams 22 and 24, between which a diameter enlargement 26 at the front end of the actuator 16 can be pressed in. If the actuator continues in the axial direction When pressed against the piston 12, the cam 24 pushes outwards and expands so that the tongues 20, so that the piston rod 14 from the piston 12 can be geldat.

Nimmt mau die Kolbenstange aus den Spritzenzylinder 10 heraus, so kann die Injektionsnadel einer weiteren Spritze oder eines anderen mit einer Hohlnadel versehenen Gefaßes in den Spritzenzylinder eingeführt werden Ura diese Hohlnadel in den vom Kolben 12 abgeschlossenen Innenraum 28 der Spritze einführen zu Können, ist der Kolben 12 mit einem aien Durohgpgskanal 30 versehen dessen Querschnitt derart bemesssen ist, daß er im wesentlichen nur den Durchtritt eine Hchluadel angemessener Größe gestattet. Auf der vom pilzförmigen Ansatz 18 abge wandten Seite des Kollbene 12 ist der Kanal 30 mit einer Ansenkung verschen, die mit 32 bezeichnet ist und zur Aufnahme eines Verschlusselements 34 dient, daß z.B. aus einem Stück oder Tropfen Silikongummi besteht.If you take the plunger rod out of the syringe cylinder 10, so can use the injection needle of another syringe or another with a hollow needle provided vessel are inserted into the syringe cylinder Ura this hollow needle into the interior space 28 closed off by the piston 12 insert the syringe To be able to, the piston 12 is provided with an aien Durohgpgskanal 30 whose cross section is dimensioned such that it is essentially only the passage of a hatchet more appropriate Size allowed. On the side of the Kollbene turned away from the mushroom-shaped extension 18 12, the channel 30 is given away with a countersink, which is denoted by 32 and is used to receive a closure element 34 that, for example, consists of one piece or a drop Made of silicone rubber.

Die zur Entnahme einer Probe aus dem Spritzeninnenraum 28 dienende hohlnadel wird durch das Verschlußelement 34 gedrückt und durch den ana1 30 in den Innenraum 28 ein geführt. Nach der Entnahme der Probe wird die Hohlnadel zurückgezogen, wobei sich das Verschlußelement 34 über dem Kanal 30 aufgrund seiner elastischen Eigenschaft wieder schließt.The one used to take a sample from the interior of the syringe 28 hollow needle is pressed through the closure element 34 and through the ana1 30 into the Interior 28 led. After the sample has been taken, the hollow needle is withdrawn, wherein the closure element 34 over the channel 30 due to its elastic Property closes again.
