Description
提示される発明は医薬品送達装置に関し、ある大きさの医薬品容器を収容するように配置され、医薬品の用量を排出するための医薬品容器に操作可能に作用する動力パックを設けられた医薬品送達装置に関する。
いくつかの機能を備えるいくつかの医薬品送達装置が特許されおよび/または市場に出回っている。特定の医薬品装置は、しばしばあるドーズ量を有するある処方された医薬品容器を扱うように設計される。
提示される出願では、「遠位部分/端部」という用語が使用されるときには、これは、装置の部分/端部、またはその部材の部分(複数可)/端部(複数可)ということを意味し、装置使用の下では、患者の医薬品送達部位から最も遠く位置する。対応して、「近位部分/端部」という用語が使用されるときに、これは装置の部分/端部、またはその部材の部分(複数可)/端部(複数可)ということを意味し、装置使用の下では、患者の医薬品送達部位から最も近く位置する。
1つの有利な機能によれば、医薬品の排出中にプランジャロッドが移動することができる直線距離を制限するために、プランジャロッドは、上記保持部材上の少なくとも1つの第2の案内係止要素と相互作用するように構成される少なくとも1つの第1の案内係止要素を備え、距離はドーズ量に対応する。この解決策の利点は、プランジャロッドが移動することができる直線距離を選択することによって、ある総体積を有する医薬品容器に作用するときに、体積が決定されることができ、かつまた変更されることができるということである。
図面の簡単な説明
以下に詳細に説明される発明の説明では、添付図面への参照が行われるだろう。
図面に示される実施形態は、ハウジング、より具体的には図1の一般的に管状の近位ハウジング部分10と、一般的に管状の遠位ハウジング部分12とを備える。ハウジング部分は、ハウジング部分を互いに接続するための取付要素とともに配置される。示される実施形態では取付要素は、図2の、遠位ハウジング部分12の近位領域の外側の表面上の周辺の畝部16と相互接続する、近位ハウジング部分10の遠位領域の内面上の、周辺の溝14を備える。しかしながら、いくつか例を挙げるとスレッド、バヨネットコネクタ、スナップインコネクタといった他の種類の取付要素もまた使用されてもよい。
棚部96が今やプランジャロッド76の外側の表面に接するために、舌部100は内向きに曲がることができない。
