For electric acupuncture devices with a maximum output voltage above 40 volts, the maximum output current should be controlled within 1 milliampere to avoid electric shock accidents.
1. When adjusting the current, it should be gradually increased from small to large, and sudden enhancement should be avoided to prevent strong muscle contractions that the patient cannot tolerate, or accidents such as bending, breaking, or fainting of the needle.
2. Patients with heart disease should avoid the current passing through the heart.
3. When using electric acupuncture near the medulla oblongata or spinal cord, the output current should be small.
4. Pregnant women should use with caution.
