Abstract

L'invention porte sur une seringue d'addition de médicament antipollution de type à résorption automatique pour préparer un médicament liquide à injection qui comprend : un corps (1), une plaque alaire (1a) fixée à l'extrémité arrière du corps (1), un piston (2) fixé dans le corps (1), une plaque de recouvrement de guidage (1b) placée au niveau de la partie d'extrémité arrière du corps (1), une tige de poussée columnaire (3) se connectant au piston (2) après pénétration à travers la partie médiane de la plaque alaire (1a), et un filtre à air (4) connecté à la partie arrière du corps (1) communiquant avec la cavité interne du corps (1). La périphérie de la tige (3) entre la plaque alaire (1a) et le piston (2) est équipée d'un tuyau de manchon de membrane flexible élastique (5), et la longueur normale du tuyau de manchon (5) est plus courte que la longueur de course du piston (2) dans le corps. La seringue pourra économiser l'intensité de travail et est pratique à utiliser.
