Title
(DE) INJEKTIONSSPRITZENKOPF
(EN) SYRINGE HEAD
(FR) TETE DE SERINGUE
Abstract
(DE)
Injektionsspritzenkopf mit Originalitätsverschluß für eine Spritzenzylinder-Kolbeneinheit, die einen Zylinderhals aufweist, der mit einem axialen Flüssigkeitsaustrittskanal und einem Umfangswulst zur Verankerung des Injektionsspritzenkopfes versehen ist, mit einer Injektionskanüle, die in einem Kanülenträger (5) montiert ist, einer Kanülenträgerführung (6), in welche der Kanülenträger über ein Gewinde einschraubbar ist, und einer Schutzkappe (1), an die über eine Sollbruchstelle ein die Kanülenträgerführung aufnehmender, mit dem Umfangswulst des Zylinderhalses zusammenwirkender Verankerungsteil anschließt, wobei die Schutzkappe am Innenumfang in Axialrichtung verlaufende Rippen (16, 16') aufweist, welche in entsprechende Nuten des Kanülenträgers für einen Drehantrieb desselben eingreifen, wobei im Verankerungsteil zwischen Kanülenträgerführung und Zylinderhals eine vom distalen Ende der Injektionskanüle durchstoßbare Dichtungsscheibe aufgenommen ist, und wobei die Schutzkappe am Innenumfang im Bereich der Kanülenträgerführung eine Anschlagrippe (16') aufweist, die in der Ruhelage der Schutzkappe an einer Seite eines am Außenumfang der Kanülenträgerführung vorspringenden Anschlages (18) anliegt.
(EN)
A syringe head with tamper evident closure for a syringe having a piston and cylindrical barrel which has a neck with an axial liquid outlet channel and a circumferential bead to secure the syringe head, with a hollow needle fitted in a holder (5), a needle holder guide (6) into which the needle holder can be screwed on a thread and a protective cap (1) against which bears, at a break point, a securing section receiving the needle holder guide and acting together with the circumferential bead on the barrel neck. The protective cap has axial ribs (16, 16') at the inner periphery which engage with corresponding grooves in the needle holder to rotate it. Between the needle holder guide and the barrel neck, there is, in the securing section, a sealing disc which can be pierced by the distal end of the needle, and the protective cap has a stop rib (16') on its inner periphery, in the region of the needle holder guide, which with the protective cap in the inoperative position bears against one side of a stop (18) projecting from the outer periphery of the needle holder guide.
(FR)
L'invention concerne une tête de seringue munie d'un dispositif de fermeture inviolable pour une seringue à corps de pompe et à piston, qui comporte un col cylindrique pourvu d'un canal axial de sortie du liquide d'injection et d'un rebord périphérique servant à ancrer la tête de seringue, une canule d'injection montée dans un porte-canule (5), un guide de porte-canule (6) dans lequel le porte-canule (5) peut être vissé par l'intermédiaire d'un filetage, et un protecteur d'embout (1) auquel se raccorde une pièce d'ancrage qui reçoit le guide de porte-canule au niveau d'un point destiné à la rupture et coopère avec le rebord périphérique du col cylindrique. Le protecteur d'embout présente des nervures (16, 16') s'étendant dans le sens axial au niveau de la périphérie intérieure. Ces nervures (16, 16') s'engagent dans des rainures correspondantes du porte-canule afin de tourner avec ledit porte-canule. Dans la pièce d'ancrage située entre le guide de porte-canule et le col cylindrique, il est prévu une bague d'étanchéité perçable par l'extrémité distale de la canule d'injection. Le protecteur d'embout comporte une nervure de butée (16') au niveau de la périphérie intérieure dans la zone du guide de porte-canule. Lorsque le protecteur d'embout est en position de repos, la nervure de butée (16') s'appuie sur un côté d'une butée (18) faisant saillie au niveau de la périphérie extérieure du guide de porte-canule.
