<p><P>PROBLEM TO BE SOLVED: To provide an electronic sphygmomanometer detecting the index indicating the degree of arterial sclerosis by person. <P>SOLUTION: The electronic sphygmomanometer for measuring the blood pressure based on the volume compensation method detects the cuff pressure within a cuff attached to a blood pressure measuring region. An arterial volume detection circuit 74 detects an arterial volume signal of the measuring region. A driving control part 101 servo-controls a cuff pressure adjusting part to regulate the arterial volume based on the detected arterial volume signal after setting the cuff pressure at initial cuff pressure. The quantity of variation of the arterial volume is detected based on the detected arterial volume signal while the servo-control is performed. If it is detected that the quantity of variation of the arterial volume is the minimum in the servo-control, a volume variation elimination rate calculating part 110 calculates the elimination rate of the volume variation (amplitude of the artery volume signal during the control/amplitude of the artery volume signal before the control), and outputs the elimination rate as the index of the arterial sclerosis. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
