Abstract：Objective To study the compatibility between different brands of injectors and injection pump, and to provide the basis for
purchasing more suitable consumptive materials for clinical departments. Methods Before using the injection pump and injectors, the
injectors should be calibrated firstly. Then the accuracy of A and B channel in injection pump under different brands of injectors could
be tested by a certain detector. Results After calibration, we found that the parameters of each brand’s injector were inconsistent. The
maximum relative error of injection accuracy in A and B channel was 12.64% and 12.4% by using Willie Ark injection pump and 4
syringes. The compatibility between domestic B, domestic C injectors and pump was the best, but the compatibility of import brands
D injectors and pump was poor, which was not recommended for clinical use. Conclusion A large amount of data is used to verify the
results, and it is proved that this research method is feasible. So it may provide a basis for the procurement of consumptive materials.
