Abstract

Ce groupe d'inventions se rapporte au domaine de la médecine et des techniques médicales, et peut être utilisé pour mélanger et distribuer des matériaux de stomatologie à deux composants. La seringue comprend un corps (1) avec une buse d'extrémité de dosage amovible (2), une cavité pour installer une cartouche à deux chambres, et deux pistons (4, 5) qui sont disposés dans le corps (1) de manière à pouvoir se déplacer en parallèle le long de chaque chambre de la cartouche (3). La buse d'extrémité de dosage (2) comprend des éléments tubulaires creux effilés (5, 6) afin de percer les chambres de la cartouche (3). La cartouche (3) est faite d'un matériau de type film élastique. Les pistons (4, 5) comportent des tiges (7, 8) qui comprennent des cavités (9) sous les éléments tubulaires creux effilés (5, 6). Les extrémités des pistons (4, 5) sont biseautées afin de comprimer les surfaces externes des parois des chambres de la cartouche (3) vers la surface interne de la cavité du corps (1). Le but est d'augmenter la commodité de dosage manuel de deux ingrédients d'un matériau de stomatologie que l'on envoie dans une quantité voulue et selon un rapport voulu en vue du mélange immédiatement avant l'utilisation de la composition obtenue dans la bouche.
