Description

Abnehmbarer und zum Tragen der Nadel dienender Spritzenboden. Es gibt Spritzen, hei denen der die Nadel tragende Spritzenboden im Innern des Sprftzenzyliinders ohne äußere Montierung befestigt ist, so daß er in idem Sprtitzenzylinder verschoben, werden und als Kolben dienen kann. Nach vorliegender Erfindung besteht ein solcher Spritzernboden oder Kolben aus zwei ineinander verschieblichen Teilen, die miteinander verschraubt sind und einen elastischen Ring zwischen sich fassen, den sie gegen die Wandung -des Spritzenzylin@ders pressen, wenn sie durch Zusammenschrauben einander genähert werden. Der dabei zusammengepreßte elastische Ring bewirkt ,dann ,eine allseitige Dichtung des Spritzenbodens oder Kolbens an die Zylinderwand.Detachable syringe base that can be used to carry the needle. There is Syringes, called the syringe base carrying the needle inside the syringe cylinder is attached without an external mount, so that it is displaced in the syringe cylinder, and can serve as a piston. According to the present invention, there is one Splash bottom or piston made of two mutually displaceable parts that are connected to one another are screwed and hold an elastic ring between them, which they against Press the wall of the syringe cylinder when they are screwed together to be approached. The thereby compressed elastic ring causes, then, one all-round sealing of the syringe base or piston on the cylinder wall.

Die .Zeichnung gibt ein Ausführungsbeispiel eines solchen Spritzenbodens bzw. Kolbens. In dem beiidersaits offenen Glaszylinder a der Spritze befindet sich das Kopfstück b des Bodens, das in der Längsrichtung zentral durchbohrt ist. Durch die Bohrung wird der lange, auf der einen Seite den Kanülenkonus c, auf der anderen Seite das Bodenstück d tragende, ebenfalls zentral .durchbQhrte Ansatz e von der Basis her durchgeschoben. Er trägt ein Gewinde, welches :das äußere Ende des Kopfstückes etwas überragt. Zwischen Kopf-und Bodenstück ist ein elastischer Ring f eingelegt. Auf das Gewinde ist vorn eine Schraubenmutter g aufgedreht.The drawing gives an embodiment of such a syringe base or piston. In the glass cylinder a of the syringe, which is open on both sides, is located the head piece b of the bottom, which is centrally pierced in the longitudinal direction. By the bore becomes the long one, with the cannula cone c on one side and the cannula cone c on the other Side, the base section d, also centrally pierced, from the Base pushed through. It has a thread, which: the outer end of the head piece something towers above. An elastic ring f is inserted between the top and bottom pieces. A screw nut g is screwed onto the thread at the front.

Hält man das .ganze System am vorderen Konusende und zieht die ,Schraubenmutter an, so preßt sich der Ring dem Glaszylinder und den Metallteilen, mit denen er in Berührung steht, fest an.Hold the whole system at the front end of the cone and pull the screw nut on, the ring presses against the glass cylinder and the metal parts with which it is in Touch stands firm.
