A pen needle assembly (701) includes a hub (731) and a metal needle (721) fixedly connected to the hub (731). A cover member (711) removably receives the hub for covering a first end of the needle (721). A sealing member (741) covers a second end of the needle (721). At least one component of the pen needle assembly (701) other than the metal needle (721) is manufactured of a biodegradable polymer, thereby providing a more environmentally friendly pen needle assembly (701) for a drug delivery device (100).

Un partie couvercle (711) reçoit de façon amovible l'embase pour couvrir une première extrémité de l'aiguille (721). Un élément de fermeture (741) recouvre une seconde extrémité de l'aiguille (721). Au moins un élément de l'ensemble (701) autre que l'aiguille (721) est en polymère biodégradable, donnant un ensemble aiguille de stylet (701) plus respectueux de l'environnement pour un dispositif de délivrance de médicament (100).
