Abstract
【解決手段】保護遮蔽システム100は、ハブ70の注入側に位置する注入端遮蔽物10であって、注射の後あるいは偶発的な始動の場合に注射針60の注入端を遮蔽する注入端遮蔽物を少なくとも具える。注入端遮蔽物は付勢しているばね80の圧力に対してハブに向かって圧縮されている。注入端遮蔽物はスリーブ50と係合し、このスリーブはハブの上に同軸に配置され、これにより、注射が行われた後に、付勢ばねが注入端遮蔽物を押してスリーブを注入端遮蔽物と共に運び注射針の注入端を覆う。スリーブはハブと係合し、注射針の注入端が注入端遮蔽物によって覆われる位置に注入端遮蔽物を固定する。本システムは非注入端遮蔽物を含むこともでき、この非注入端遮蔽物は、ペン型注射器がハブとのねじ係合を外されるとき、非注入端遮蔽物を、注射針の非注入端を保護する位置に固定する。
