- 薬物送達装置であって、
薬物と、薬物容器アセンブリ内部に配置されたプランジャーとを収容し、前記薬物の投与のための出口を有し、初期位置においては前記出口が封止されている、薬物容器アセンブリと、
前記プランジャーまたは前記薬物容器に圧力を加えて前記薬物を加圧するよう構成される第1の蓄積エネルギー源を備える駆動メカニズムと、
使用時に前記薬物を送達する皮下注射針と、
前記針を前記薬物容器アセンブリに対して動かすよう自動的に注射部位に挿入するよう構成される針挿入メカニズムと、
を備え、
前記装置は、前記第1の蓄積エネルギー源の解放によって与えられる前記薬物の液圧が、前記針挿入メカニズムの動作に用いられるよう構成され、第1の解放メカニズムは前記薬物が加圧された後に前記出口を開封し、
前記薬物容器アセンブリの一部であっても分離した部分であってもよい主筐体と、皮膚接触要素とをさらに備え、
前記皮膚接触要素は前記装置の前端部を形成し、前記皮膚接触要素の前記主筐体に対する初期位置から挿入位置への移動により、前記第1の解放メカニズムが動作するまたは動作可能となる、薬物送達装置。 - 前記第1の解放メカニズムは、針ハブ要素を前記薬物容器アセンブリに対して動かすように動作して前記出口を開封する、請求項1に記載の薬物送達装置。
- 前記針の遠位端を封止する第1の封止部材と、前記針の外部と前記薬物容器アセンブリの間の封止となる第2の封止部材とをさらに備える薬物送達装置であって、
前記第1の解放メカニズムは、前記針を前記第1の封止部材に対して動かして前記針の遠位端を開封する、請求項2に記載の薬物送達装置。 - 前記針は、患者に挿入する近位端と、前記薬物を受ける遠位端とを有し、前記針ハブは、前記針ハブが初期位置にあるとき前記出口を封止するよう構成される封止部をさらに有し、前記針ハブは、前記針の遠位端の周囲に位置する入口部を有し、前記入口部は、前記針ハブが挿入位置にあるとき、前記出口と前記針の遠位端の間の流体連結をもたらす、請求項2に記載の薬物送達装置。
