A pressure plate is connected to the piston and all individual parts are made of plastic. USE/ADVANTAGE - In medical practice, for the admin. of multiple injections of the same dose.

Description

Die Erfindung betrifft ein Dosiergerät nach dem Oberbe­ griff des Anspruches 1.The invention relates to a metering device according to the Oberbe handle of claim 1.

Der gattungsgemäße Gegenstand stellt ein Dosiergerät dar, welches beispielsweise im medizinischen Bereich Mehrfach-Injektionen gleicher Dosis auf einfache Weise und in gewohnter Handhabung erlaubt.The generic object is a dosing device which, for example, in the medical field Multiple injections of the same dose in a simple way and allowed in the usual way.

Zur Erfüllung solcher Aufgaben sind entweder aufwendige, elektrisch betriebene Dosierapparate bekannt, deren mo­ biler Einsatz umständlich ist, oder Einwegspritzen, deren Benützung bei Mehrfachanwendung zeitaufwendig ist und in ihrer Summe einen höheren Werkstoff-Abfall verursachen.To perform such tasks, either complex, electrically operated metering devices known, the mo biler use is cumbersome, or disposable syringes, the Use in multiple applications is time consuming and in cause a higher waste of materials.

Der Erfindung liegt die Aufgabe zugrunde, ein Gerät zu schaffen, welches eine Erweiterung des einfachen und be­ währten Konzepts der Einweg-Spritze darstellt und welches auch in der Handhabung möglichst geringfügig hiervon ab­ weicht und außerdem eine unproblematische Abfallverwer­ tung zuläßt.The invention has for its object to a device create, which is an extension of the simple and be represents the concept of the disposable syringe and which in handling as little as possible gives way and also an unproblematic waste disposal allowed.

Diese Aufgabe wird bei einer gattungsgemäßen Einrichtung durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Um bei einem solchen Dosiergerät sicherzustellen, daß eine unbeabsichtigte Betätigung nicht möglich ist, wird der Kolben in der Ausgangsstellung gegen Längsverschie­ bung dadurch gesichert, daß dieser einerseits an einem Gehäuse-Anschlag, andererseits vermittels einer Griff­ hülse an einer Anschlagklammer zur Anlage kommt. (Fig. 1) Eine andere Ausbildung, die ebenfalls die Sicherung des Kolbens in der Ausgangsstellung gewährleistet, wird da­ durch erreicht, daß ein Gegenhalter zwischen einer Gabel­ klammer, bestehend aus Anschlag und Klammer, zu liegen kommt und daß die besagte Klammer radial zu einer Rille ein- u. ausrastbarbar ist. This object is achieved in a generic device by the characterizing features of claim 1. In order to ensure in such a metering device that an unintentional actuation is not possible, the piston is secured in the initial position against longitudinal displacement by the fact that it comes into contact with a stop on the one hand on a housing stop and on the other hand by means of a grip sleeve. ( Fig. 1) Another training, which also ensures the securing of the piston in the starting position, is achieved by that a counter-holder between a fork, consisting of a stop and a clamp, comes to rest and that the said clamp is radial to one Groove in and out can be disengaged.

In weiterer Ausgestaltung sind zur Begrenzung der Teil­ hübe Anschlagklammern vorgesehen, die federnde Schenkel aufweisen und radial zu einer Rille ein- u. ausrastbar sind.In a further embodiment, the part is limited Rough stop clamps are provided, the resilient legs have and radially to a groove u. can be disengaged.

Die mit der Erfindung erzielbaren Vorteile bestehen ins­ besondere darin,daß mit wenigen und einfachen Mitteln eine mehrfach wiederholbare Dosierung möglich ist, die in ihrer Genauigkeit der Positionsgenauigkeit der Anschlagklammern entspricht, was auf einfache Weise durch den genauen Ab­ stand der Rillen erreichbar ist. Weiterhin ist sicherge­ stellt, daß keine unbeabsichtigte Betätigung, weder in der Ausgangsstellung, noch in einer Zwischenstellung erfolgen kann, solange keine bewußte Entsperrung durch Abziehen der Anschlagklammern vorgenommen wird.The advantages that can be achieved with the invention are special in that with few and simple means a repeatable dosing is possible in their Accuracy of positional accuracy of the stop clips corresponds to what is simply by the exact Ab the groove can be reached. It is also safe represents that no unintentional activity, neither in the starting position, still in an intermediate position can take place as long as there is no deliberate unlocking by Pulling off the stop clamps is made.

Ein weiterer Vorteil besteht darin, daß alle Einzelteile in einer Materialsorte herstellbar sind, ohne daß die Funktion beeinträchtigt wird. Dadurch wird das Dosier­ gerät nach Gebrauch voll recycle-fähig.Another advantage is that all items can be produced in one type of material without the Function is impaired. This makes the dosing fully recyclable after use.

Diese weist ein Mundstück 1 auf, an welches ein Injek­ tionselement mittels Kupplung 2 anschließbar ist. An das Mundstück 1 sind Gegenhalter 3 angeformt, die zur Abstützung der Finger bei Betätigung dienen. Das Mund­ stück 1 ist an einem Zylinder 5, mittels Verbindung 4 fixiert. Am Zylinder 5 befinden sich im Abstand h, Ril­ len 6, in welche eine Anschlagklammer 7 einrastbar ist. Ein Vorratsraum 9 wird begrenzt durch einen Innendurchmesser 8, Mundstück 1 und der Stirnfläche eines Kolbens 10. Der Kolben 10 ist dichtend und gleitend im Innendurchmesser 8 geführt. In der gezeichneten Ausgangsstellung liegt der Kolben 10 an einem Bund 11 an, an welchen eine Dichtung 12 angeformt ist. Der Kolben 10 geht über in einen Schaft 13, der seinerseits mit einer Griffhülse 14 über einen Zapfen 15 steckbar oder fest verbunden ist. Die schrittweise Abgabe des im Vorratsraum 9 befindli­ chen, fließfähigen Stoffes erfolgt dadurch, daß die an der Griffhülse 14 anliegende Anschlagklammer 7 an deren Griff-Fläche 16 senkrecht zur Geräte-Achse abziehbar ist. Dadurch wird der Kolben 10 mittels der Griffhülse 14 um den Dosierweg h bis zur nächsten Anschlagklammer 7 vorrückbar. This has a mouthpiece 1 , to which an injection element can be connected by means of a coupling 2 . Brackets 3 are formed on the mouthpiece 1 and serve to support the fingers when actuated. The mouth piece 1 is fixed to a cylinder 5 by means of connection 4 . On the cylinder 5 are at a distance h, Ril len 6 , in which a stop bracket 7 can be locked. A storage space 9 is delimited by an inner diameter 8 , mouthpiece 1 and the end face of a piston 10 . The piston 10 is sealingly and slidably guided in the inner diameter 8 . In the initial position shown, the piston 10 rests on a collar 11 on which a seal 12 is molded. The piston 10 merges into a shaft 13 , which in turn is pluggable or firmly connected to a grip sleeve 14 via a pin 15 . The gradual release of the Chen in the storage room 9 , flowable material takes place in that the abutting on the grip sleeve 14 stop clip 7 on the handle surface 16 is removable perpendicular to the device axis. As a result, the piston 10 can be advanced by the gripping sleeve 14 by the dosing path h to the next stop bracket 7 .
