内容記述 | 体内埋込型圧センサーの実用化を目指して、体内埋込型定常流補助人工心臓用流入圧センサーの自動校正方法に関する基礎研究を行った。自動校正ロジックとしては、大気圧の代わりに胸腔内圧を利用し、かつ流入カニューレによる心室のサッキング現象を利用して、サッキングが解除された瞬間の流入圧が胸腔内圧を反映するため、この圧をゼロ点補正のための校正圧とした。流入圧波形から校正圧を検出するアルゴリズムを、模擬循環回路を用いて検証した結果、ばらつきの少ない検出ができることがわかった。また、動物実験より、高精度の校正はできないものの、校正圧の平均値を用いれば、流入圧センサーの自動校正が可能であることがわかった。 | |||||
