Abstract

La présente invention concerne une seringue jetable à usage unique comportant un corps creux, un ensemble d'aiguille disposé dans le corps creux, et un ensemble de piston dans le corps creux. L'ensemble de piston comporte une portion de châssis de forme allongée comprenant au moins un chemin de guidage entre ses extrémités. Un organe d'escamotage est fixé de manière amovible à une extrémité du châssis et un organe d'accrochage, comprenant un élément d'accrochage, est positionné avec un guide conformé de manière à se déplacer dans le chemin de guidage du châssis de piston. Un organe élastique s'étend entre l'organe d'escamotage et l'organe d'accrochage. Un ensemble de retenue est assujetti à l'extrémité opposée du châssis de piston et est conformé à recevoir et à fixer l'élément d'accrochage procurant ainsi une tension à l'organe élastique. L'ensemble d'aiguille et l'organe d'escamotage présentent des éléments d'accouplement, permettant de relâcher la tension de l'organe élastique et d'escamoter les moyens d'injection dans le corps creux après l'accouplement entre l'ensemble d'aiguille et l'organe d'escamotage. L'invention concerne également un procédé de fabrication d'une telle seringue.
