Abstract：The color doppler ultrasound is one of the fully functional examination AIDS, which can provide a clear and
comprehensive picture for doctors to help them make further diagnosis. The basic working principle of Philips IU22 color doppler
ultrasound was analyzed in this paper, and then the repair methods for two typical faults were summarized, one of which was the
occurrence of black screen, the other was the unrecognized convex array probe. Through the gradual analysis and maintenance,
the color doppler ultrasound equipment returned to normal. We summarized a set of maintenance methods, which could provide a
