Claims (12)
- 生物の心臓用の循環補助装置(22)であって、少なくとも1つの誘電エラストマー膜によって心臓(10)に周期的に圧力を加えるためのカフを含み、前記少なくとも1つの誘電エラストマー膜は制御装置によってパルス的に血液を運ぶために心拍と同期して制御することができ、前記カフは、前記心臓(10)の外側の上で引っ張られるように設計され、この目的のために少なくとも心室の外側の領域において心臓の外側の輪郭に適合する内側の形状を有し、
前記カフは、前記誘電エラストマー膜を含む外側の収縮層(24)と内側のパッド層(26)とからなり、前記パッド層(26)は非圧縮性の液体で満たされ、少なくとも1つの出口弁(28)を有し、前記出口弁(28)は、通常状態では閉じ、緊急状態では開いていることを特徴とする循環補助装置(22)。 - 前記パッド層(26)は、前記収縮層(24)の少なくとも1回の収縮ストロークに対応する厚さを有することを特徴とする請求項1に記載の循環補助装置(22)。
- 前記収縮層(24)は、時間をずらした順序で別々に電気的に制御可能である多数の環状部分からなることを特徴とする請求項1に記載の循環補助装置(22)。
- 前記収縮層(24)には3から250個の環状部分が設けられていることを特徴とする請求項3に記載の循環補助装置(22)。
- 前記パッド層(26)は、それぞれ収縮層の環状部分の下方に配置された同数の液体で満たされた環状空間からなり、各環状空間は独自の出口弁を有することを特徴とする請求項3に記載の循環補助装置(22)。
- 前記パッド層(26)は、前記出口弁(28)を介して収集バッグ又は身体から排出するための排出ラインと連通することを特徴とする請求項1から5のいずれか一項に記載の循環補助装置(22)。
- 前記パッド層(26)の非圧縮性の液体は生理学的に許容可能であり、前記出口弁(28)を通じて身体の中に放出され得ることを特徴とする請求項1から6のいずれか一項に記載の循環補助装置(22)。
- 前記パッド層(26)の非圧縮性の液体は、正の変力作用を有する少なくとも1つの物質を含むことを特徴とする請求項6に記載の循環補助装置(22)。
- 前記制御装置は、指定された期間に前記収縮層(24)への電力供給が最小値を下回った場合に緊急状態を検出する緊急状態検出ユニットを有することを特徴とする請求項1から8のいずれか一項に記載の循環補助装置(22)。
- 請求項1から9のいずれか一項に記載の循環補助装置(22)と、制御装置(30)と、電源装置と、心周期を検出するための少なくとも1つのセンサ装置とを含む循環補助システム。
- 循環補助装置(22)が生物の心臓の上で引っ張られて固定され、センサユニットが前記心臓(10)に取り付けられることを特徴とする請求項1から10のいずれか一項に記載の循環補助システムを生物の身体に導入する医療方法。
- 前記心臓(10)の心周期が検出され、これに同期して収縮層(24)に電力が供給されることを特徴とする請求項1から10のいずれか一項に記載の循環補助システムを使用して生体の血液の循環を補助する方法。
