Abstract: A pulse diagnostic device and a system of pulse diagnosis are provided. The pulse diagnostic device includes a cuff and a main monitor. The cuff includes a tube and an air bag arranged with an air path interface. A gas medium is received in the air bag. The tube is connected to the air path interface. The main monitor includes a pressure sensor and a controller. The tube extends to reach the main monitor and is connected to the pressure sensor, and the pressure sensor further connects to the controller. When the pulse diagnostic device is working, the cuff contacts an artery, the pressure sensor senses a pressure of the gas medium in the tube. The pressure sensor transmits the pressure of the gas medium to the controller. The controller obtains the pulse information and the blood pressure information based on the pressure of the gas medium.
