Description
本発明は、薬剤送達装置用の投与量設定機構に関し、特に、予め規定された最大許容量を有する投与量設定機構に関する。また、本発明は、このような投与量設定機構を含む薬剤送達装置に関する。
市場には、薬剤を送達するための装置が多数存在している。このような装置において、薬剤は、例えば、シリンジ、カートリッジなどの容器に配置されており、容器内に設けられた可動ストッパを押すことによって、注射針またはノズルなどの送達部材を通って排出される。
本発明の目的は、従来装置の欠点を解消する薬剤送達装置を提供することである。
他の局面、特徴および利点は、上記の概要から、ならびに図面および特許請求の範囲を含む以下の説明から明らかになるであろう。
図1は、本発明の一実施形態に係る薬剤送達装置を示す斜視図である。薬剤送達装置は、近位端および遠位端を有し、近位部または近位端11と遠位部または遠位端12とを有するハウジング10を備える。組み立てられた薬剤送達装置において、ハウジング10は、薬剤送達装置の外表面または外観の一部を形成する。本明細書に記載されたハウジングの技術的特徴が任意のスリーブ状または管状の部材に含まれ得るため、以下、ハウジング10を管状部材10と称する。
