Description
Technical Field
The application relates to the technical field of magnetic field control, in particular to an alternating magnetic field stimulation realization method and magnetic stimulation equipment.
Background
Magnetic stimulation is a non-invasive intervention, and there is a study of applying magnetic stimulation to apply a rapidly changing magnetic field to the brain of a patient so as to induce weak currents in the brain of the patient by electromagnetic induction. These weak currents alter the natural electrical activity of the patient's brain, thereby providing treatment to the patient, helping diagnosis or mapping brain function in neuroscience research.
Conventional magnetic stimulation devices typically include an electromagnetic coil that is fixed in position relative to the patient's head. The fixed structure of conventional devices limits the magnitude of the magnetic field that can be applied to the patient, since the magnetic field applied to the patient is a function of the solenoid configuration, the current through the solenoid, and the position of the solenoid relative to the patient. Furthermore, conventional magnetic stimulation devices typically use very high currents in the electromagnetic coil in order to obtain a sufficiently strong magnetic field strength, which increases the risk of accidental injuries to the patient due to electric shock, burns, seizures, etc.
Clearly, there is a need for a portable magnetic stimulation device that can focus magnetic stimulation on their targets for more powerful magnetic stimulation, while producing less additional impact on healthy tissue is desirable in the marketplace. However, a small electromagnet cannot generate a strong enough magnetic field strength, while a permanent magnet can have both a small volume and a large magnetic field strength, but is a static magnetic field and cannot be applied to the related application fields of magnetic stimulation.

In one embodiment, referring to fig. 5, it is known that the stimulation device can be configured as a therapeutic device, and the stimulation device is adjusted to the appropriate location at the tumor height. The stimulation units are arranged in pairs according to the principles of the application, and preferably, the embodiment is an example of the arrangement of 8 stimulation units.
In another embodiment, as shown in fig. 6, in the same pair of stimulation units, the first permanent magnet 101 and the second permanent magnet 102 are rotated by the first motor 301 and the second motor 302, and a composite alternating magnetic field is obtained therebetween. The first motor 301 and the second motor 302 obtain the voltage and direction provided by the motion control module 800 through switches 701 and 702. Since the first motor 301 and the second motor 302 control the voltage source according to the same rotation speed such that the N pole of the first permanent magnet 101 and the S pole of the second permanent magnet 102 are in the position of fig. 6, the magnetic field strength therebetween reaches the maximum value. If the first motor 301 and the second motor 302 are in uncontrolled free rotation, it cannot be guaranteed that N, S is rotated to opposite positions at the same time to obtain maximum magnetic excitation between the magnets.
In order to control the magnets to rotate exactly to a certain position at the same time the N pole of the first permanent magnet 101 and the S pole of the second permanent magnet 102, the moving positions of the magnets need to be acquired.

The induced voltage signals collected by the first magnetic induction coil 201 and the second magnetic induction coil 202 are amplified and shaped by the first signal processing module 401 and the second signal processing module 402 to become two square wave signals with phase difference. The phase detection module 500 measures the phases of the two signals to obtain the time t of the phase difference. The first switch 701 and the second switch 702 are normally in a closed state, while the same rotation speed is obtained under the control of the motion control module 800. The phase control module 600 controls the first switch 701 and the second switch 702 to cut off the rotation speed control voltage for a period of t according to the phase difference output by the phase detection module 500, so as to realize the synchronous and same-speed rotation of the relative positions of the first permanent magnet 101 and the second permanent magnet 102.
In practical applications, multiple sets of the apparatus shown in fig. 5 may be used to achieve stimulation of a particular location. The systems of the plurality of groups will obtain the strongest magnetic stimulus at the intersection point of their strongest magnetic flux paths.
