Main and collateral channel detection device and method

The invention relates to a main and collateral channel detection device and method. The main and collateral channel detection device comprises a fixed position signal collection module, a control module and a plurality of measurement position signal collection modules. The fixed position signal collection module makes contact with a selected fixed acupuncture point. The measurement position signal collection modules make contact with acupuncture points relevant to the main and collateral channels of the human body. The fixed position signal collection module making contact with the selected fixed acupuncture point and any one of the measurement position signal collection modules fixed to the acupuncture points relevant to the main and collateral channels of the human body form a closed electric loop along the main and collateral channels. The control module controls collection and transmission of electric signals of the closed electric loop along the main and collateral channels. Multi-path main and collateral channel electric signals can be nearly collected at the same time, and therefore the detection speed, efficiency and accuracy for the main and collateral channels of the human body are greatly improved.
