Non-invasive arteriovenous pressure measuring device and arteriovenous pressure measuring method using the measuring device

摘要

A non-invasive arteriovenous pressure measuring device capable of measuring an arteriovenous pressure noninvasively and accurately and an arteriovenous pressure measuring method using the measuring device are provided. A non-invasive arteriovenous pressure measuring device, a probe (20) that irradiates ultrasonic waves toward blood vessels in the skin, and a pressing unit that is sandwiched between the skin and the probe (20) and presses the skin (10) and a pressure sensor (33) for detecting a pressing force on the skin in the pressing portion (10), the pressing portion (10) includes water (36) that transmits ultrasonic waves, water ( 36) and a balloon (31) formed of a flexible material that transmits ultrasonic waves, and presses the skin on the outer surface of the balloon (31).
