Abstract

L'invention concerne une seringue pour injecter de la poudre, cette seringue comprenant un cylindre (11), sur lequel est montée une aiguille (2), ainsi qu'un flacon de médicament divisé en une cavité supérieure (12) et une cavité inférieure (7), des éléments d'étanchéité se trouvant entre les cavités et sur l'orifice de la bouteille. La partie raccord (20) du cylindre (2) de la seringue est insérée dans un orifice découpé de l'élément d'étanchéité sur l'orifice du flacon. L'aiguille (11) du cylindre (2) de la seringue est disposée dans la cavité supérieure (12) du flacon de médicament. Un élément de sécurité est placé entre le cylindre (2) de la seringue et la double cavité pour éviter un déplacement relatif de ceux-ci. Lors de l'utilisation de la seringue, tant que l'élément de sécurité entre le cylindre (2) et la double cavité est rompu, le cylindre (2) de la seringue peut être poussé pour insérer l'aiguille (11) dans la cavité inférieure (7). Si le piston (1) du cylindre (2) de la seringue est poussé davantage, le solvant (14) se mélange alors à la poudre (13). La solution étant homogène après avoir été agitée, l'injection peut être réalisée par extraction de l'aiguille. La seringue de la présente invention est ainsi de structure simple et de manipulation aisée. En outre, elle ne provoque pas de contamination et son utilisation est sûre.
