Problems solved by technology
However, because the magnetic induction intensity decays exponentially with distance, it is difficult for existing instruments to effectively stimulate the deep part of the brain, or to allow the superficial layer of the brain to receive super-strong stimulation in exchange for effective stimulation of the deep part; although, patents: (96180330.4) and other technologies are expected to meet There is a need for deep focused magnetic stimulation, but it is difficult to generate a high-energy magnetic field at the same time to achieve a high frequency. At present, the operating frequency of rTMS is generally up to 25Hz
In addition, the current magnetic stimulation devices commonly used in biomedical applications usually use one or more circular coils arranged in a plane, and are used on one side of the part that needs to be stimulated, so the research direction is limited to magnetic stimulation. focus and the resulting neurophysiological significance

Embodiment 2
[0045] Another embodiment 2 of the present invention has the same structure as embodiment 1. Through the setting and control of the control circuit, a combination of the other two waveforms is generated, so that the coil pair generates a corresponding magnetic field, such as Figure 7As shown, waveform A is a continuous sawtooth wave with a frequency of 1000 Hz and lasts for 3 minutes, waveform B is an intermittent triangle wave with a frequency of 2 Hz and a duration of 3 minutes. Minutes constitute a magnetic stimulation process.

The invention relates to a central nervous system magnetic activate system, relative control circuit and application, wherein the invention uses control circuit to output wave signal to the drive power supply to output relative current to the coil; via the shape, size, coils and distance of coil, generating time-change magnetic field between coupled coils, to function the brain; and the central nervous system will receive the magnetic activation with accurate wave, high frequency, and multi-frequency combined cooperated magnetic activation, to treat insanity or recover brain.
Description
technical field [0001] The invention relates to a central nervous system magnetic stimulation device, a control circuit thereof, and a method for using the device. Background technique [0002] Diseases of the central nervous system are considered to be the number one killer in the 21st century: with the increase in the rhythm and pressure of life, more and more people suffer from mental diseases such as depression; epidemiological surveys have found that schizophrenia and depression have a high prevalence rate, especially the lifetime prevalence rate is extremely high. After the 1990s, the survey results of depressive disorders in some special groups showed that the prevalence rate was more than 10-20 per thousand. At present, in addition to drugs and psychotherapy, in terms of physical factor therapy, it is mainly realized by electrical stimulation or magnetic stimulation. Among them, the main development field of magnetic stimulation technology is TMS (time-varying magn...
