Abstract
The present invention provides an arteriovenous pressure measurement device which allows noninvasive and accurate measurement of arteriovenous pressure, and also provides an arteriovenous pressure measurement method using the measurement device. The noninvasive arteriovenous pressure measurement device comprises a probe (20) for radiating ultrasound toward a blood vessel in the skin, a pressing part (10) for pressing the skin in a state of being placed between the skin and the probe (20), and a pressure sensor (33) for detecting a pressing force applied to the skin at the pressing part (10), the pressing part (10) having water (36) permeable to the ultrasound and a balloon (31) accommodating the water (36), the flexible container (31) being made of a flexible material permeable to the ultrasound, and an outer surface of the balloon (31) presses the skin.
