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、少なくとも注射器胴部と、前記注射器胴部の内部において移動可能であり前記注射器胴部の内容物を通常は中空針を介して放出するピストン手段とを備え、
前記デバイスは、中空本体(10)と、ばね(20)と、プランジャ(30)とを具備し、前記中空本体(10)は、内部の係止構成(18)を有し、かつ、前記注射器胴部(41)と、前記中空本体(10)の外部に突出した針(42)を有するピストン手段(45,46)とを収容するように構成されており、前記ばね(20)は前記デバイスの使用初期において前記中空本体(10)と前記注射器胴部(41)との間で圧縮されるように配され、その結果前記注射器胴部(41)は前記係止構成(18)によって前記ばね(20)の力に抗して保持され、前記プランジャ(30)は、前記注射器(40)の前記ピストン手段(45,46)を動かすように前記中空本体(10)内にスライド可能に位置すると共に、前記プランジャ(30)の前端部において前記中空本体(10)への挿入方向に、前記中空本体(10)の前記係止構成(18)を前記注射器胴部(41)から開放するように作動する係止開放構成(34)を有し、前記係止開放構成(34)の作動によって前記ばね(20)が前記針(42)を含む前記注射器(40)全体を前記中空本体(10)の内部へ引き込むことが可能となり、また、前記プランジャ(30)は前記ばね(20)がそのように作動した後に前記注射器(40)の少なくとも一部分を受入れるチャンバ(36)を更に提供しており、
前記プランジャ(30)は、前記プランジャ(30)の前端部において前記中空本体(10)への挿入方向に、かつ前記係止開放構成(34)から離れた位置に、前記ピストン手段(45,46)のピストンロッド(45)に当接し移動させることが可能な可撓性先端部材(33)を有し、前記中空本体(10)は、前記注射器胴部(41)を保持する前記係止構成(18)から離れた位置に、前記プランジャ(30)の前記可撓性先端部材(33)を前記注射器胴部(41)の引き込み行路外に撓ませる働きをする内部撓み手段(22)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有し前記主チャンバから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延びている前方チャンバを画成する、請求項1に記載のデバイス。
- 前記中空本体の前記係止構成は、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対して半径方向の外側に位置する、請求項2に記載のデバイス。
- 前記係止構成は、前記デバイスの使用初期において前記中空本体の長手方向の軸と平行に、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自由端まで延びており、前記係止構成は半径方向外側に可撓性を有することにより、前記捕獲手段により前記注射器胴部を捉えることができると共に、前記捕獲手段から前記注射器胴部を開放することが可能である、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開放を行う、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中空本体の前記長手方向軸にほぼ平行に延び、前記中空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、前記プランジャのうち、前記プランジャの移動方向の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(40)及び請求項1〜10のいずれかに記載の注射器のためのアクチュエータおよび収容デバイスを備えた組立体であって、前記注射器(40)は少なくとも、前記注射器胴部(41)、および前記注射器胴部(41)の内部において移動可能であり前記注射器胴部(41)の内容物を通常は針(42)を介して放出するピストン手段(45,46)を具備し、前記デバイスの前記中空本体(10)は、前記注射器胴部(41とピストン手段(45,46)を収容し、前記ばね(20)は前記中空本体(10)の内部に配置されて前記デバイスの中空本体(10)と前記注射器胴部(41)との間で作動する組立体。
- 注射器及び請求項11に記載の注射器のためのアクチュエータおよび収容デバイスを備えた組立体であって、前記針は、初期には前記本体外部に突出している。
