摘要：A pressure cuff (200; 500) is fastened to the brachium to cause ischemia in thebrachium by a blood impediment bladder (210; 520) of the cuff. A sound wave sensor(110) and a pressure sensor (120) are provided in the rear bladder (230; 530) on the

downstream side of the blood impediment bladder to detect Korotkoff sound and pulsewave. The standard internal pressure in the pressure cuff is controlled by an air pumpand a leak valve controlled by the CPU (130; 430; 0). By monitoring the Korotkoffsound or the pulse wave, the standard internal pressure in the pressure cuff can bemaintained at a diastolic pressure. The pulse wave obtained in the brachium at the time ofthis pressure approximates to the aortic wave. This approximate aortic wave is displayedtogether with the Korotkoff sound and its envelope curve, and an output that givesinformation on the trouble of the blood circulation in the circulatory organ system isperformed.
