Chinese pulse wave measuring device and use method thereof

A pulse wave measuring device for pulse diagnosis, configured to measure a vascular radial displacement pulse wave of an arterial blood vessel at a test area of a subject, the pulse wave measuring device comprising:

• an airbag having a transparent window and a contact part, wherein the contact part is used to contact a skin of the test area of the subject to be tested, at least one arterial vessel is under the test area;
• a pressure control module used to control an internal pressure of the airbag;
• a displacement sensing module used to measure a real-time distance from the skin of the test area of the subject to the displacement sensing module over a period of time, so as to obtain the vascular radial displacement pulse wave of the arterial blood vessel, and wherein a measurement resolution of the displacement sensing module is below 50 μm;
• and
• a computer communicating with the pressure control module and the displacement sensing module respectively, used to transmit control signals to the pressure control module and the displacement sensing module respectively, receiving information sent by the pressure control module and the displacement sensing module, and performing calculations, wherein the computer is configured to process signals from the displacement sensing module to determine the vascular radial displacement pulse wave of the arterial blood vessel.
