Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a magnetic field generator treatment device. Background Art

[0002] Studies have found that magnetic fields have a significant impact on the human body and other organisms, and the effects of magnetic fields can be used to treat various diseases in organisms.

[0003] The magnetic induction therapy device disclosed in a Chinese patent (Publication No. 101601608) generates an alternating magnetic field through an alternating magnetic field generator and an electromagnetic induction coil connected to the alternating magnetic field generator. In order to raise the temperature of the tumor tissue to the therapeutic temperature, the magnetic material implanted in the tumor tissue needs to generate sufficient heat energy under the action of the alternating magnetic field, thus requiring the magnetic induction intensity of the alternating magnetic field to reach a certain value.

[0004] However, existing magnetic field therapy devices have the following shortcomings: 1. Low energy efficiency: high-intensity magnetic fields consume a lot of electricity; 2. Single function: general magnetic field therapy devices can only generate static or low-frequency magnetic fields, and their magnetic fields have poor penetration effect on human tissue, resulting in weak magnetic therapy effects. Summary of the Invention

[0005] The present invention provides a magnetic field generator treatment device to solve the problems raised in the above background technology.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A magnetic field generator therapeutic device comprises a base plate, the upper side of the base plate is fixedly connected to a vertical plate, the side wall of the vertical plate is fixedly connected to a support platform, the side wall of the support platform is fixedly connected to a controller, the controller is electrically connected to an electromyography sensor and a temperature sensor, the side wall of the vertical plate is connected to a mounting tube through a universal tube, the bottom end of the mounting tube is fixedly connected to a fixing ring, the inner ring of the fixing ring is connected to a swivel through a rotating device, a platinum sheet is fixedly connected to the inner bottom of the swivel, arc electrodes are fixedly connected to both sides of the upper side of the platinum sheet, an insulating layer is provided on the surface of the arc electrodes, a current input device is provided on two of the arc electrodes, a ferromagnetic layer is provided between the two arc electrodes, a femtosecond laser is provided on the inner top of the mounting tube, the femtosecond laser is located directly above the ferromagnetic layer, an L-shaped rod is fixedly connected to the bottom side of the fixing ring, one end of the L-shaped rod is fixedly connected to a magnetic field sensor, and the magnetic field sensor is located below the platinum sheet.

[0008] Preferably, the rotating device includes a motor, an annular groove is provided on the inner ring side wall of the fixed ring, the motor is fixedly connected to the side wall of the annular groove, the output shaft of the motor is fixedly connected to a driving gear, the driving gear is meshed with a gear ring, the gear ring is against the side wall of the annular groove, and the gear ring is fixedly connected to the outer wall of the rotating ring.

[0009] Preferably, the current input device includes two L-shaped conductive rods, the two conductive rods are respectively fixedly connected to the side walls of the two arc-shaped electrodes, and a positive conductive block and a negative conductive block are embedded on the inner ring side wall of the mounting cylinder. The femtosecond laser is made of insulating material, and the positive conductive block and the negative conductive block do not contact each other and are at the same center of a circle. The upper ends of the two conductive rods are respectively against the inner side walls of the positive conductive block and the negative conductive block, and the positive conductive block and the negative conductive block are respectively electrically connected to the positive and negative poles of the DC power supply.

[0010] Preferably, the material of the ferromagnetic layer is Co 40 Fe 40 B 20 .

[0011] Preferably, the magnetic field sensor is used to detect the intensity and frequency of the magnetic field, and the magnetic field sensor is electrically connected to the controller.

[0012] Preferably, the steps for using the magnetic field generator treatment device are:

[0013] The first step is to align the bottom of the mounting tube with the area of ​​the patient that needs magnetic field treatment, and then attach the electromyography sensor and temperature sensor to the area of ​​the patient that needs magnetic field treatment;

[0014] The second step is to start the DC power supply, so that the positive and negative conductive blocks transmit positive and negative currents through the conductive rods to the two arc-shaped electrodes, causing the ferromagnetic layer to generate internal magnetization under the action of the external electric field. Then, the femtosecond laser is started, which can emit femtosecond laser pulses into the double-layer structure of the ferromagnetic layer and the platinum sheet. The double-layer structure of the ferromagnetic layer and the platinum sheet is excited by the femtosecond laser to generate a spin current. The spin current is converted into a transverse charge flow through the inverse spin Hall effect, forming an ultrafast current, and then a terahertz-band magnetic field is radiated from the bottom of the platinum sheet to perform magnetic therapy on the patient's body part.

[0015] The third step is to start the motor again. The motor drives the gear ring to rotate through the driving gear. The gear ring can drive the ferromagnetic layer and the platinum sheet to rotate through the rotating ring, thereby causing the magnetic field radiated from the bottom of the platinum sheet to rotate, forming a gyromagnetic magnetic field. At the same time, the rotation of the rotating ring can drive the two conductive rods to rotate. The rotation of the two conductive rods will alternately connect with the positive conductive block and the negative conductive block, so that the electrodes of the two arc electrodes alternate between positive and negative. Then, the direction of the ferromagnetic layer affected by the external electric field changes repeatedly, and the S pole and N pole of the magnetic field generated by the ferromagnetic layer and the platinum sheet also change alternately. The gyromagnetic magnetic field forms a dynamically rotating magnetic field through the alternating changes of the magnetic poles. This dynamic characteristic enables it to more effectively penetrate human tissue and produce stronger biological effects, thereby improving the treatment effect.

[0016] Preferably, a magnetic field therapy quality assessment unit is provided in the controller, and the magnetic field therapy quality assessment unit is used to associate the body impact index with the magnetic field impact index to form a magnetic field therapy quality assessment coefficient. If the magnetic field therapy quality assessment coefficient is lower than the preset magnetic field therapy quality coefficient threshold, control information for controlling the femtosecond laser is formed, and the magnetic field strength and frequency generated by the ferromagnetic layer and the platinum sheet are adjusted by adjusting the energy intensity and frequency of the femtosecond laser pulses generated by the femtosecond laser, so that the magnetic field therapy quality assessment coefficient reaches the preset magnetic field therapy quality coefficient threshold.

[0017] Preferably, the magnetic field treatment quality evaluation unit is used to associate the body impact index with the magnetic field impact index to form a magnetic field treatment quality evaluation coefficient, specifically:

[0018] The muscle electrical activity signal values ​​and skin temperature values ​​of the magnetic therapy site obtained by the electromyography sensor and the temperature sensor are correlated to form a body impact index. The magnetic field intensity and magnetic field frequency obtained by the magnetic field sensor are correlated to form a magnetic field impact index. The obtained body impact index and magnetic field impact index are then correlated to form a treatment quality evaluation coefficient. The correlation model of the treatment quality evaluation coefficient is expressed as follows:

[0019]

[0020] Among them, ZLG represents the treatment quality evaluation coefficient; ZF represents the body impact index; ZG represents the magnetic field impact index; T represents the skin temperature value of the magnetic therapy area; W represents the muscle electrical activity signal value of the magnetic therapy area; Q represents the magnetic field intensity; R represents the magnetic field frequency; α, β, γ, and δ are all weight coefficients set by the user.

[0022] 1. The present invention designs a double-layer structure of a ferromagnetic layer and a platinum sheet, and utilizes the inverse spin Hall effect in spin electronics to convert the spin current excited by the femtosecond laser into a transverse ultrafast current, thereby radiating a terahertz-band magnetic field. The femtosecond pulse energy is on the order of nJ, and the device power consumption is low;

[0023] 2. The magnetic field of the present invention is a gyromagnetic magnetic field with alternating magnetic poles. Compared with static or low-frequency magnetic fields, the dynamically rotating magnetic field can more effectively penetrate human tissue and produce stronger biological effects, thereby improving the therapeutic effect.
