Abstract

L'invention concerne un ensemble (10) seringue qui comprend un cylindre (12) présentant une surface (22) interne et une extrémité (24) de distribution sensiblement close délimitant une ouverture (26) de distribution. Une butée (34) est montée sur la surface (22) interne du cylindre (12). Un piston(14) est placé à l'intérieur du cylindre de la seringue de manière à coulisser. Le piston présente une surface de scellement à son extrémité avant et à son extrémité arrière. La surface (39) de scellement de l'extrémité avant et la surface (45) de scellement de l'extrémité arrière sont espacées l'une de l'autre par une première distance. Le piston (14) peut être déplacé entre une première position et une seconde position. La tige (18) de piston comprend au moins un doigt (76) proéminent dont l'extrémité distale est configurée pour venir s'appuyer contre la butée (34) lorsque le piston (14) se trouve dans la seconde position. L'extrémité distale du ou des doigt(s)(76) ne dépasse pas la première distance à partir la butée (34) lorsque le piston (14) se trouve dans la première position.
