Claims (12)
- 注射器のためのアクチュエータおよび収容デバイスであって、少なくとも胴部と、前記胴部のどんな内容物でも通常は中空針を介して放出するための前記胴部の内部における移動可能なピストン手段とを備え、前記デバイスは、中空本体と、ばねと、プランジャとを具備し、ここで前記中空本体は、内部の係止構成を有し、かつ前記本体の外部に突出した針を有するピストン手段と前記注射器胴部とを収容するのに適合しており、前記ばねは前記本体と前記注射器胴部との間で作動するように配され、その胴部は前記デバイスの使用初期においては前記係止構成を使用して前記ばねの力に抗してそのまま保持され、前記プランジャは前記注射器の前記ピストン手段の代わりをするために前記本体内にスライド可能に位置し、前記本体の前記係止構成がそれによって前記注射器胴部から解除され、前記ばねがいかなる針をも含む前記注射器全体を前記中空本体内部へ引き込み可能とするような手段を供給し、またさらに前記ばねがそのように作動した後に前記注射器の少なくとも一部分を受入れるためのチャンバを供給するもので、前記プランジャは、それによって前記ピストンロッドに当接し変位させることが可能な可撓性先端部材を有し、前記中空本体は前記プランジャの前記先端部材を前記注射器胴部の引き込み行路外に撓ませる働きをする内部撓み手段を有すること、を特徴とする注射器のためのアクチュエータおよび収容デバイス。
- 前記中空本体は一般的に円筒形状であり、長手方向の軸を有し、また、その内部に前記プランジャがスライド可能に位置された主チャンバと、前記主チャンバより小さな断面をしていてプランジャの移動終端を超えて前記注射器胴部の奥まで前記主チャンバから伸びている前記注射器胴部前方チャンバを画成する、請求項1に記載のデバイス。
- 前記本体の係止構成は前記本体の前記主チャンバ内に前記前方チャンバに隣接して供され、前記前方チャンバに関して外側半径方向に位置する、請求項2に記載のデバイス。
- 前記係止構成は一般的に前記中空本体の長手方向軸と平行に伸び、前記ばねの力に抗して前記注射器胴部を保持するための半径方向内側に方向付けされた捕獲手段を有する端部を解放していて、前記係止構成はまた半径方向外側に可撓性があり、そのため前記捕獲手段により前記注射器胴部を捉えることが出来、後でそれからの開放を可能にする、請求項2または3に記載のデバイス。
- 前記プランジャと前記係止構成は協働する平面部を有し、それにより前記プランジャは前記係止構成の半径方向外側への撓みを可能にし、前記注射器胴部の前記捕獲手段からの解放を行う、請求項4に記載のデバイス。
- 前記中空本体と前記プランジャは前記本体の前記長手方向軸にほぼ平行に伸び、前記本体と前記プランジャとの間の相対回転を最小にする互いに協働する案内手段を有する、請求項2〜5のいずれかに記載のデバイス。
- 前記中空本体は1部品として型成形され、前記係止構成はそれとともに一体に成形される、請求項1〜6のいずれかに記載のデバイス。
- 前記係止構成は前記中空本体の内部に対称的に配置された請求項1〜7のいずれかに記載のデバイス。
- 前記可撓性先端部材は前記プランジャの前記前方先端に対称的に配置された請求項1〜8のいずれかに記載のデバイス。
- 中空本体と、ばねと、プランジャのみで構成された請求項1〜9のいずれかに記載のデバイス。
- 注射器とアクチュエータを備えた組立体、および前記注射器のための請求項1から10のいずれかに記載の収容デバイスであって、前記注射器は胴部、中空針および胴部内容物を前記針を介して放出する前記胴部内の排除移動可能なピストン手段、を具備し、前記デバイスの前記中空本体は、前記注射器胴部と初期には前記本体外部に突出した針の付いたピストン手段を収容し、前記ばねは前記本体内部に配置されて前記デバイス本体と前記注射器胴部との間で作動する、組立体およびデバイス。
- 注射器とアクチュエータを備えた組立体、および前記注射器のための請求項1〜10のいずれかに記載の収容デバイスであって、前記注射器は少なくとも前記胴部および前記胴部の内容物を通常は針を介して放出する前記胴部内の排除移動可能なピストン手段、を具備し、前記デバイスの前記中空本体は、前記注射器胴部とピストン手段を収容し、前記ばねは前記本体内部に配置されて前記デバイスの本体と前記注射器胴部との間で作動する、組立体およびデバイス。
