Description
前記説明した手段によってインペラ1の磁石14と磁気駆動装置3の磁石31とのマグネットギャップを異ならせた血液ポンプを準備し、インペラの回転速度とインペラの回転軸の頂部すなわち上部ピボットの頂部の公転直径(revolutional diameter)との関係を測定した。その結果を図11に示している。公転直径は上部ピボットの頂部の振れ回りを表わしており、小さい方が好ましい。図11は公転直径を最小とするマグネットギャップがインペラの回転速度に応じて異なっており、回転数が高くなると、マグネットギャップを小さくした方がよいことを示している。図11において星印マークは磁気駆動装置の磁石の回転トルクがインペラの磁石に伝達できなくなる状態すなわち脱調(de-coupling) が生じたことを示すもので、マグネットギャップが大きい場合に脱調が生じ易い。
