What are the domestic and international EMC (electromagnetic compatibility) standards for air wave pressure therapy devices?

Air wave pressure therapy devices (used for lymphedema, varicose veins, etc.) must meet GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international) EMC standards. They generate cyclic pressure by controlling the sequential inflation and deflation of air bladders through an air pump and multiple solenoid valves. Standards require accurate air pressure control timing, stable pressure sensor readings, and immunity to electrical noise from the air pump motor and solenoid valves, ensuring the reliability of treatment modes and pressure levels. The equipment is typically used in rehabilitation departments, where the environment is relatively mild.
