    摘要： The present invention discloses a closed-loop hydraulic circuit for in vitro simulation of blood flow and for testing the effect of such simulated flow on a biological sample, comprising:
    - a tank for storing a flowing liquid;
    - a constant flow pump for pumping the liquid out of the tank for imposing, in use, an average constant flow in the hydraulic circuit;
    - a pulsating pump for superimposing to said average constant flow a variable flow having a zero average flow rate;
    - a test section for receiving a biological sample to be tested under flow conditions imposed by the said means;
    - means for regulating the pressure downstream of the test section;
    - pressure and flow sensors for sensing pressure and flow conditions in the test section;
    - means for measuring and collecting biological data in the test section;
    - a control unit comprising regulation means for controlling the constant flow pump and the pulsating pump.
