- 耳小骨連鎖の全部又は一部を置換し、患者の中耳における第1の点を第2の点にカップリングするための人工耳小骨(ORP)であって、
圧力差を構成する変化可能な構造を有するカップリングを備え、
前記カップリングは、前記カップリングの構造を変化させるための2つの相対移動可能部を有する流体充填チャンバーを有し、
前記カップリングは、リーク手段、及び前記チャンバー内部の流体移動を可能とする流路手段とを構成する非封止手段を備え、
前記相対移動可能部の相対移動は、前記チャンバー内の流体移動によって制御され、
前記移動可能部の相対移動が圧力の準静的変化に応じて可能とされ、かつ可聴周波数に対応した振動変化に応じて実質的に規制されるように、前記チャンバーは流体移動を制限するように構成されることを特徴とするORP。 - 前記カップリングが、前記非封止手段を備えた流体を収容するコンテナとピストンとを備え、前記コンテナの壁と前記ピストンとの間に設けられたクリアランスが、前記リーク手段および前記流路手段を構成することで前記流体が変位し、かつ
患者の聴覚系内部の要素間においてカップリングされるように構成された第1および第2の取付点を有し、
前記カップリングに対する音振動から導かれる力の付与に応じて、前記流路内部の前記流体の相互作用は、リーク手段を有する前記ピストンと前記コンテナによって、前記カップリングが実質的に非変形でかつ剛体であることを可能とし、さらに前記第1及び第2の取付点が実質的に互いに相対的に固定されることを可能とし、
前記カップリングに対する局地的な周囲圧力の変化から導かれる力の付与に応じて、前記流路内部の前記流体の相互作用は、リーク手段を有する前記ピストンと前記コンテナによって、前記第1及び第2の取付点間の相対移動が可能にされるように前記カップリングを変形させることを可能とすることを特徴とする請求項1に記載のORP。 - 前記流体は、非ニュートン流体であることを特徴とする請求項1または2に記載のORP。
- 前記非ニュートン流体はダイラタント流体であることを特徴とする請求項3に記載のORP。
- 前記非ニュートン流体は、揺変性の流体であることを特徴とする請求項3に記載のORP。
- 前記流体は、ニュートン流体を備えることを特徴とする請求項1又は2に記載のORP。

- 前記カップリングは、前記第1及び第2の取付点間において相対的に回転運動可能なように変形するように構成されることを特徴とする請求項2に記載のORP。
- 前記カップリングの剛性は、変化可能であることを特徴とする請求項1または2に記載のORP。
- 前記カップリングの剛性は、付与された荷重の周波数変化に応じて変化可能であることを特徴とする請求項1または2に記載のORP。
- 前記カップリングの剛性は、付与された荷重の周波数増加に応じて増加することを特徴とする請求項1または2に記載のORP。
- 前記カップリングの剛性は、付与された荷重の大きさの変化に応じて変化可能であることを特徴とする請求項1または2に記載のORP。
- 前記カップリングの剛性は、付与された荷重の大きさの増加に応じて低下することを特徴とする請求項1または2に記載のORP。
- 前記カップリングは、前記第1及び第2の取付点間に与圧が与えられるように構成されることを特徴とする請求項2に記載のORP。
- 前記カップリングの前記ピストンは、前記コンテナ内部に滑動自在に取り付けられ、前記ピストンは流体界面を定義することを特徴とする請求項2に記載のORP。
- 前記カップリングの前記ピストンは、前記コンテナ内部に回転自在に取り付けられる回転可能軸手段を構成することを特徴とする請求項2に記載のORP。
- 前記回転可能軸手段は、その上に取り付けられ、かつそこから径方向に延在する少なくとも1つの翼を備えることを特徴とする請求項16に記載のORP。
- 前記少なくとも1つの翼は、前記コンテナ内部に含まれる流体に係合するように採用されて、流体界面を定義することを特徴とする請求項17に記載のORP。
- 前記翼は、前記流体がそれを通って又はそれを横切って通ることが可能となるように構成されることを特徴とする請求項17又は18に記載のORP。
- 前記カップリングは、第1の摩擦要素が前記第1の取付点を支持し、第2の摩擦要素が前記第2の取付点を支持するように、摩擦カップリングによってともにカップリングされる第1及び第2の摩擦要素を備え、前記摩擦カップリングは、前記カップリングが患者の聴覚系内部の1つの要素から他の1つへ音誘起振動を伝達可能とするように構成されることを特徴とする請求項2に記載のORP。
