Abstract:
Objective To explore the methods for suppressing the interferences during the application of medical electronic devices.Methods Kinds of signal sources interfering medical electronic devices were analyzed,and the suppression methods were discussed from the aspects of shielding protection,selection of ground point,filtering,circuit design and etc.Results Interference suppression could be executed by proper grounding,shielding protection,component protection and etc.Conclusion Suppression methods have to be selected according to inference source during the clinical application of medical electronic devices.
