Vascular characteristic measuring device and vascular characteristic measurement manner

摘要

Vascular characteristic measuring device 100, sensor unit 30 of the optical type which is internalized in the blood current measurement sections 20 containment in the position where it opposes to the skin surface 10 of the measured field of the subject and blood current measurement sections 20 and electrocardiograph has 40 and control unit 50. Control unit 50, blood current measurement means 60 and vascular displacement guidance means has 70 and vascular state guidance means 80. Blood current measurement means 60, when from light-emitting part 32 of sensor unit 30 the light which radiation is done absorbing light with light sensing portion 34,36, the displacement of system around vascular and vascular by the blood current on the basis of optical strength, measure. Vascular displacement guidance means 70 guide the displacement of the inner wall of vascular 12 on the basis of the displacement of system around vascular and vascular. As for vascular state guidance means 80, the ripple mark of the heart telegraphic number of electrocardiograph 40 and the pulsating wave propagation velocity in each measurement position the ripple mark of the detection signal which is obtained from light sensing portion 34,36 with the phase contrast is calculated, displacement state of the inner wall of vascular 12 is guided from particular pulsating wave propagation velocity.
