Drug injection device and recovery system

A drug injection device consists of a body, a cap, a striker, a runner, a button, a spring, an ampoule and an optional needle. Each of the main body, the cover, the striker, the runner and the button is a molded plastic component, mainly made of polycarbonate, which can be slid, snapped, screwed or resting in place without the use of adhesives or fasteners. Also disclosed is a system for recovering a drug injection device having molded plastic parts made predominantly of polycarbonate, including detaching the drug injection device, separating the molded plastic parts from all other parts, and reprocessing the molded plastic parts together into a regenerated resin, which may be by regrinding, melting, and granulating. 一种药物注射装置由主体、盖、撞件、转轮、按钮、弹簧、安瓿和任选的针头组成。主体、盖、撞件、转轮和按钮中的每一个是模制塑料部件，主要由聚碳酸酯制成，其可以滑动、卡扣、旋拧或搁置就位，无需使用粘合剂或紧固件。还公开了一种用于回收具有主要由聚碳酸酯制成的模制塑料部件的药物注射装置的系统，包括拆卸药物注射装置、将模制塑料部件与所有其它部件分离、以及将模制塑料部件一起再加工成再生树脂，这可以是通过再研磨、熔融和造粒。
