An inflatable tourniquet cuff for surrounding the extremities in one place, and a tourniquet instrument for releasably connectable to the cuff, tourniquet apparatus for quickly and accurately measuring limb occlusion pressure of the patient, the tourniquets vessel is responsive to said cuff pressure signal to a pressure sensing means for producing an indicating cuff pressure signal the pressure level in the cuff in is connected to the cuff, and adjusting the pressure of the cuff in the vicinity of the reference pressure level blood flow and conversion means applied to produce the pressure adjusting means for, the blood flow signal indicative of the blood flow in the partial is applied to the portion of the terminal from the cuff of the limb, the cuff pressure and the blood flow signal the magnitude of the arterial pulsation is small lowest cuff pressure than the minimum detection threshold and in response to the signal, detects the arterial pulsation of blood flow, also, increase the reference pressure level in synchronization with the arterial pulsation and an operable closure means pressure to produce a limb occlusion pressure values shown. [Selection] Figure Figure 1患者の四肢閉塞圧力を迅速かつ正確に測定するためのタニケット装置は、一箇所で四肢を取り巻くための膨張可能なタニケットカフと、該カフに解放可能に接続可能なタニケット器とを含み、該タニケット器は、カフ中の圧力レベルを指示するカフ圧力信号を生じるための圧力感知手段と、カフと接続され、基準圧力レベルの近傍に前記カフ中の圧力を調節するために前記カフ圧力信号に応答する圧力調整手段と、前記四肢の前記カフから末端側の部分に適用され該部分で血流を示す血流信号を生じるように適用される血流変換手段と、前記血流信号および前記カフ圧力信号に応答し、血流の動脈の拍動を検出し、動脈の拍動と同期して前記基準圧力レベルを増大させ、また動脈の拍動のマグニチュードが最小検出閾値より小さな最も低いカフ圧力を示す四肢閉塞圧力値を生じるように動作可能な閉塞圧迫手段とを含む。【選択図】図1
