Claims (14)
- カテーテルの作業ルーメンに対して可変的な速度の吸引を提供するのに適している装置であって、マニホルドとポンプとばねとを備えている装置において、
前記マニホルドが入口ポートと出口ポートと滑り弁とを有しており、前記滑り弁が前記入口ポートと前記出口ポートとの間に配置されていて、前記滑り弁は開位置と閉位置とを有していて、そして第一逆止め弁が前記マニホルドの中に配置されており、前記入口ポートと流体連通していて、前記入口ポートは前記カテーテルの前記作業ルーメンと流体連通しており、
前記ポンプが前記マニホルドに連結されていて、前記ポンプはポンプルーメンと前記ルーメン内に配置されているプランジャとを画定するハウジングを有していて、前記プランジャが前記ポンプルーメンの中で完全に遠位方向に前進させられる場合、前記プランジャが前記滑り弁に接触し、そして前記滑り弁を前記開状態に保つように前記ポンプは前記マニホルドに連結されており、
前記ばねは前記滑り弁を閉位置に付勢するために前記滑り弁に結合されていて、
前記プランジャを近位方向に後退させることにより前記滑り弁が前記閉位置に移動し流体が前記ポンプルーメンに流入し、従って前記プランジャを近位方向に後退させることにより、前記カテーテルの前記作業ルーメンに対する吸引速度が変化し、そして前記プランジャを遠位方向に前進させることにより、前記ポンプルーメンの中の流体が前記出口ポートを介して流出する、
装置。 - 前記出口ポートは、患者の静脈脈管構造と流体連通している静脈管路に連結されている請求項1に記載の装置。
- 前記マニホルドの前記出口ポートに連結されている、中に配置されているフィルタを有するフィルタチャンバをさらに備える請求項1に記載の装置。
- 前記フィルタチャンバは前記出口ポートから取り外し可能である請求項3に記載の装置。
- 前記入口ポートと前記出口ポートとの間の前記マニホルドの区画の中に配置されている滑り弁をさらに備える請求項1に記載の装置。
- 前記滑り弁は、第1の端部と、第2の端部と、そのブロックの中央領域を横方向に通って延びる穴とを有するブロックをさらに備える請求項5に記載の装置。
- 前記ブロックは楕円形の形状を有する請求項6に記載の装置。
- 前記ブロックは長方形の形状を有する請求項6に記載の装置。
- 前記マニホルドは、前記カテーテルの前記作業ルーメンと流体連通している吸入/注入ポートをさらに備える請求項1に記載の装置。
- 前記ハウジングは、ポンプ補助吸引速度の量を表示するための複数の印をさらに備える請求項1に記載の装置。
- 体液が前記入口ポートから前記ハウジングのポンプチャンバの中に流れ込むことを可能にするように構成されている、前記マニホルド内に配置されている第1の逆止弁をさらに備える請求項1に記載の装置。
- 前記第1の逆止弁は、前記プランジャが遠位方向に前進させられる時に閉じるように構成されている請求項11に記載の装置。
- 前記ハウジングのポンプチャンバから前記出口ポートに向かう方向に体液が流れることを可能にするように構成されている、前記マニホルド内に配置されている第2の逆止弁をさらに備える請求項1に記載の装置。
- 前記第2の逆止弁は、前記プランジャが近位方向に後退させられる時に閉じるように構成されている請求項13に記載の装置。
