(Medical Engineering Department, Daping Hospital and Institute of Surgery Research ，Third Military Medical University, Chongqing, 400042) [Abstract]　A pulse wave monitoring system based on LabVIEW was designed which can automatically, efficiently and accurately real-time collect and record human pulse parameters .With a single chip processor as the core, the system used a lower computer and a upper computer to measure the pulse of human body. The system could magnify, filter analog signal and rise the voltage through the pulse sensor. It realized the communication between the MCU and the PC through a CH341T chip connecting with the PC’s USB interface. The processed data could be transmitted to the upper computer for analysis. The upper machine based on LabVIEW could realizes user login management, pulse wave filtering, eliminating baseline drift, feature recognition and print of reports, etc.The characteristic parameters could effectively reflect and feedback the patients’ physical features and functions.
