Description

Technical Field

[0001] The utility model belongs to the field of brain rehabilitation auxiliary equipment, and specifically relates to a head-mounted transcranial magnetic stimulation device. Background Art

[0002] Transcranial magnetic stimulation technology is a painless, non-invasive and green treatment method. Its principle is to stimulate the cerebral cortex by generating low-frequency electromagnetic waves to achieve the effect of treating neurological diseases such as depression. The existing head-mounted transcranial magnetic stimulation device fixes the electromagnetic group on the headgear. The patient wears it on the head, and the electromagnetic group emits electromagnetic waves to the attached part. During the magnetic stimulation process, the electromagnetic wave intensity may be greater than the patient's tolerance, which may cause abnormalities in the patient's physiological indicators such as EEG activity and heart rate. If corresponding adjustments are not made in time, the probability of adverse reactions such as muscle soreness, dizziness and even epilepsy will increase. Therefore, when the existing head-mounted transcranial magnetic stimulation device is used, it must be connected to additional physiological index monitoring equipment, and the relevant professional operators must adjust the electromagnetic group in a timely manner according to the relevant indexes to ensure safe use and reduce the side effects of magnetic stimulation.
