[Therapeutic instrument for brain circulation function on the basis of direct digital synthesis technology]

Electricity can stimulate cerebral fastigial nucleus to increase regional cerebral blood flow (rCBF) and narrow the volume of infarct, therefore its effect on ischemic brain disorder may be helpful. The therapeutic instrument for brain circulation function based on direct digital synthesis (DDS) technology uses the domestic newest scientific findings and others in foreign countries. Adopting the DDS technology directly, it institutes safe and efficacious treatment. Through pasting the electrodes on body surface, the non-invasive instrument introduces electric current to cerebral fastigial nucleus (FN) and hence it improves the state of brain blood supply and nerve conduction, increases cerebral blood flow, reduces the number of necrotic neurons in the district of penumbra, and mitigates brain edema. Consequently, it improves the function of brain circulation.
