Description
本発明は、投与量設定機能を備える薬剤送達装置に関する。
注射器などの薬剤送達装置は、時として、ある範囲内で変動し得る特定の投与量をユーザが設定できる機能を備えている。
本発明の目的は、先行技術の薬剤送達装置の欠点を改善することであり、単純かつ直観的な方法で所望のまたは必要な投与量を設定できる装置を提供することである。
本願では、「遠位部/遠位端」という用語が用いられる場合、これは、注射装置の使用下で患者の薬剤注射箇所から最も遠く離れた場所に位置する注射装置の部分/端部またはその部材の部分/端部を指す。対応して、「近位部/近位端」という用語が用いられる場合、これは、注射装置の使用下で患者の薬剤注射箇所の最も近くに位置する注射装置の部分/端部またはその部材の部分/端部を指す。
