Objective The bioreactor is an important facility for tissue engineering research. A research platform of bioreactor system for blood vessel on the virtual instrument was built. Method Slider-crank mechanism was used in this system to strain the bellows so as to simulate pulse flow of human blood vessels. This system can measure and control such parameters as pressure by using LabVIEW platform, and by connected with PC, the remote watch and control could be realized, which primarily achieved step-control and automatization. Result Experiments show that the bioreactor was able to exert appropriate biomechanical stimulation to cells, and detect various parameters accurately. Conclusions This bioreactor system for bloodvessel on the virtual instrument was valuable in practical application.
