摘要：
A multi-use needle assembly (200) for an injection device (50), wherein the injection device (50) comprises: a housing (52) and a cartridge (54) for storing a liquid drug for multiple injections, the multi-use needle assembly comprises: a support structure (201), needle cannula (210), a movable shield assembly comprising a movable shield (220) and an actuation member (222) fixed to the shield (220), and a cleaning assembly (230) adapted to change configuration by deformation. The shield (220) is adapted to be in a locked distal position, an unlocked distal position and an unlocked proximal position, and the cleaning assembly (230) is adapted to be configured in (i) an open configuration, wherein a gap is provided between an outer surface of the cannula (210) and the cleaning assembly (230) to allow adjustment of the relative axial position between the cleaning assembly and the cannula, (ii) a closed configuration, wherein the cleaning assembly (230) is configured to provide contact with the outer surface of the cannula to enable cleaning of the cannula. The actuation member (222) is adapted to deform and thereby operate the cleaning assembly (230) between the open and the closed configuration, in response to turning the shield between the unlocked and the locked configuration. The needle assembly (200) is adapted to enable cleaning of the cannula (210), when the shield (220) is in the locked distal position, and to allow exposure of the cannula (210), when the shield (220) is in the unlocked distal position.La présente invention concerne un ensemble aiguille multi-usage (200) pour un dispositif d'injection (50), le dispositif d'injection (50) comprenant : un boîtier (52) et une cartouche (54) pour stocker un médicament liquide pour de multiples injections, l'ensemble aiguille multi-usage comprenant : une structure de support (201), une canule d'aiguille (210), un ensemble de protection mobile comprenant une protection mobile (220) et un élément d'actionnement (222)
