A needle assembly (10; 210) for a prefilled injection syringe is described. A needle holder (12; 212) has a needle (14; 214) secured to it and is adapted to be secured to a syringe barrel of the injection syringe. A needle sheath (16; 216) has a distal end forming a releasable sterile seal with the needle holder (12; 212), and surrounds and shields the needle (14; 214) . A needle seal (18; 218) surmounts the needle tip and is arranged at least in part in the proximal end of the needle sheath (16; 216) and closed off by a closure element (20; 220) . A closure connection between the closure element (20; 220) and the needle sheath (16; 216) is configured as a non-releasable and sterile barrier (54; 254) produced by means of bonding or welding.
La présente invention concerne un ensemble aiguille (10; 210) pour un système de seringue préremplie. En l'occurrence, on utilise un porte-aiguille (12; 212) équipé de son aiguille (14; 214) et conçu pour être solidaire du corps de la seringue d'injection. On utilise également un protège-aiguille (16; 216) dont l'extrémité distale forme avec le porte-aiguille (12; 212) une enveloppe stérile amovible. Un bouchon d'aiguille (18; 218) enserrant la pointe d'aiguille prend sur une partie au moins du protège-aiguille (16; 216), une coiffe (20; 220) venant fermer l'ensemble. Entre la coiffe (20; 220) et le protège-aiguille (16; 216), on a réalisé par collage ou soudage une liaison étanche faisant office de barrière stérile non séparable (54; 254).
