A safety syringe (11) is disclosed. The safety syringe has a retractable needle facility (14/15) incorporated therein, the syringe comprising a barrel (12) and plunger (13) and needle assembly. The needle is caused to retract into the barrel of the syringe upon completion of injection once it has been used, by means of engagement between the needle assembly and the end of the plunger. Locking means (28) preferably in the form of a locking bush is provided in the body of the syringe to engage the plunger once it is retracted after use, so that the syringe is rendered incapable of being used further.
La présente invention vise une seringue de sécurité (11) à fonctionnalité intégrée d~aiguille rétractable (14/15). La seringue comprend un cylindre (12), un piston (13) et un ensemble d~aiguille. Un moyen de prise entre l~aiguille et l~extrémité du piston entraîne la rétraction de l'aiguille dans le cylindre de la seringue après usage à la fin de l~injection. Un moyen de blocage (28) ayant de préférence la forme d~une garniture de blocage est installé dans le corps de la seringue pour venir en prise avec le piston après usage une fois qu~il est rétracté, de façon à rendre toute autre utilisation de la seringue impossible.
