Abstract

L'invention porte sur un seringue utilisée pour des préparations de nécessaires d'injection et comprenant une valve coulissante intermédiaire accueillie dans le cylindre de la seringue, rempli d'un liquide médicinal au moins sur un côté d'actionnement du plongeur de la valve coulissante intermédiaire. Cette valve comprend une lèvre annulaire venant en contact avec la paroi interne du cylindre de la seringue afin de diviser l'espace de façon hermétique en un espace côté aiguille du cylindre et un espace côté actionnement plongeur ; un trou traversant contournant la lèvre annulaire et établissant une communication entre l'espace côté aiguille du cylindre et l'espace côté actionnement plongeur ; un dispositif de fermeture destiné à obturer le trou traversant et un dispositif de rupture du joint qui rompt le joint lorsqu'une injection oblige la valve coulissante intermédiaire à atteindre l'extrémité côté aiguille du cylindre ou sa proximité. Cet agencement permet de réaliser des injections successives, fiables, de liquide médicinal au moyen d'un cylindre spécifique de seringue.
