Abstract

L'invention concerne un dispositif médical comprenant un bouchon de type clapet élastique, placé à l'intérieur du col d'un récipient contenant un médicament liquide et une aiguille transperçant ledit bouchon, sur l'extrémité supérieure duquel est ménagée une rainure de guidage. Un clapet élastique s'étend entre la partie inférieure de la rainure de guidage et la surface inférieure du corps de bouchon le long du sens axial. Ce clapet se ferme normalement sous l'effet d'une force élastique et s'ouvre sous l'effet d'une force qui lui est appliquée. La rainure de guidage est fermée par un obturateur élastique. L'aiguille comprend une extrémité supérieure solide de perçage correspondant à la forme de la rainure de guidage et un corps présentant un passage pour liquide, ainsi qu'un pore radical situé sur la paroi latéral du corps, à proximité de l'extrémité supérieure de perçage. Ce pore est en communication fluidique avec le passage ménagé dans le corps.
