<p>An external counterpulsation device with precise control and movement includes a precise power system, a hydraulic bag (A,B,C) filled with liquid, a transmission system for liquid pressure, and a control system (9) for acquiring, processing and displaying information, as well as sending commands. The precise power system is moved linearly by a servomotor (1) cooperated with a ball screw (2). A liquid enwrapping and compressing device using water as medium receives the power from the ball screw and quickly transmits the pressure to a human body surface, so as to achieve the purpose of counterpulstion. The counterpulstion device precisely controls the counterpulstion by relevant information acquired from human body.</p> |
