Abstract

Un appareil daide à linjection par seringue comprend un corps présentant une ouverture inférieure définie par une bague dactionnement, un piston dinterfaçage de seringue essentiellement contenu de manière coulissante dans le corps et un mécanisme de verrouillage fixé de manière pivotante au corps. Le mécanisme de verrouillage est configuré pour empêcher le mouvement vers lavant du piston dinterfaçage de seringue lorsquil est en position de verrouillage et pour permettre un mouvement vers lavant dudit piston lorsquil est en position déverrouillée. La position déverrouillée est activée par contact externe avec la bague dactionnement.
