Title: 呼吸器の状態の音響検出
IPC: A61B7/04
Filed: 2001-10-01
Abstract: 患者の呼吸器系の状態を検出するための診断方法を提供する。この方法では、患者の胸部・肺での音の発生やその伝播の特徴を、基準音の特徴及び／又は所定のしきい値と比較分析した上で、患者に異常な呼吸器の状態が存在するかどうかを決定する。本方法では、患者内の呼吸器の状態と相互に作用し、胸壁にぶつかる音波や振動を処理する。その音波や振動は、患者（１２）の口及び気管内に音波を放射するスピーカー（２０）によって生成されても、また、固有の音であってもよい。その代わりには、患者（１２）の胸壁を叩いて音波・振動を生成する方法も採用される。上記音波の処理（３８）においては、この診断方法は、高及び低周波数帯域内のエネルギー値，信号の時間遅延及び又は優位周波数を用いてエネルギー比を算出し、その算出値を所定の基準しきい値と比較して、患者内の特定の呼吸器の状態をあらわす出力を生成する。
