Description
第2のシールドはハブの非注入端で、第2の凹部の内側で移動する。ハブ中間壁の非注入側に対して押された第2の弾性部材は、非注入端シールドを完全移動位置にハブの非注入端に向けて保持している。したがって、非注入端のシールドは、ハブの非注入端に針がペン注射器の隔壁に挿入される圧縮された位置から、ペン注射器が取り外されたときシールドが針の非注入端をカバーする完全移動位置へ移動し、弾性部材により適所に保持される。
図1はアンロック位置、すなわち、機器が最初に組み立てられて、無菌の外装において出荷される状態の安全ペン針を示す。この状態において、非注入端のシールド40(「第2のシールド」としても参照される)は、伸長され、針カニューレ20をカバーし、ペン注射器に組み立てる準備が整っている。ペン注射器190(図2示される)は、時々、カートリッジとしても参照され、医薬品のガラスびんを備えている。「ペン注射器」または「カートリッジ」は、ハウジング、またはガラスびんを含む全体の組立品を事情に応じて参照できる。ペン注射器190は、ねじ切りされた接続部によりハブ11の凹部54への挿入に適合してもよいが、ペン注射器をハブに挿入し保持する特定のメカニズムは特定的ではない。
