Abstract

L'invention concerne une seringue perfectionnée du type ayant un corps creux fermé par un dispositif d'injection à l'une de ses extrémités et ouvert à l'autre. L'extrémité ouverte reçoit un piston de forme allongée qui glisse dans le corps creux et expulse le contenu du corps à travers le dispositif d'injection. L'amélioration réside dans le fait qu'un élément élastique rétracte le dispositif d'injection dans une gaine protectrice.
