[0002] The microcurrent therapy device is a low-frequency electrical stimulation with a frequency of less than 1000Hz and a current intensity of less than 1mA (1000uA).

[0042] On the basis of the original embodiment 2, this embodiment preferably has three electrode points 24 on the cylindrical electrode head 2, and the electrode point 24 is located on the end face of one end of the cylindrical electrode head 2.
