In view of the obvious subjectivity and individual differences caused by the dependence on hand-brain feedback in traditional medicine,in order to improve the accuracy of symptom judgment,a three-part pulse collection wristband diagnosis system is designed by combining modern pulse diagnosis theory with modern sensor technology.The system is designed based on micro-balloon.Three inflatable wristbands are inflated by air pump,and the air pressure in the wristbands is controlled to simulate the pulse taking pressure.Air pressure sensor is selected to represent the information of pulse diagnosis with digital signal,and the gas in the wristband is exhausted through the exhaust valve.The upper computer software is designed to realize the functions of system control,pulse visualization and storage.The system has been tested multiple times in the clinic,with good accuracy and stability,and can record the patient's pulse image information completely.
