Description

Technical Field

[0001] This invention relates to the field of pulsed magnetic therapy medical devices, and more particularly to a transcranial magnetic stimulation device based on a combination of strong and weak magnetic stimulation. Background Technology

[0002] Currently, in existing technologies, pulsed magnetic therapy with adjustable intensity via single-pulse magnetic field has not been accepted by the market due to its limited treatment method and inability to provide continuous treatment.
