[0034] Specifically, first, you can turn knob 3, and the rotation of knob 3 drives gear 5 to rotate inside protective shell 4, thereby adjusting the size of the closed loop of headband 1. After the position and size of headband 1 are adjusted, turn handle 26 to drive screw 25 to rotate inside fixed plate 24. This process can make rubber pad 27 fit tightly against the patient's head, further ensuring that headband 1 fits tightly against the patient's head.

During the ultrasonic stimulation treatment, the coil 30 connected by the elastic band 29 can also generate electromagnetic waves to perform magnetic stimulation treatment on the patient. This design provides patients with a variety of treatment options.

[0037] The outer wall of the headband 1 is fixedly connected to a temperature sensor 48, the upper surface of the fixed ring 8 is fixedly connected to a centrally symmetrical elastic band 29, the outer wall of the elastic band 29 is fixedly connected to a coil 30, the bottom end of the elastic band 29 is fixedly connected to a top plate 31, the upper surface of the top plate 31 is fixedly connected to a biofeedback sensor 32, the lower end of the outer wall of the elastic band 29 is fixedly connected to a water bag 28, the outer wall of the water bag 28 is fixedly connected to a magnet 2 40, the outer wall of the magnet 2 40 is provided with a magnet 1 39, the outer wall of the magnet 1 39 is fixedly connected to an outer shell 33, the inner wall of the outer shell 33 is fixedly connected to a dustproof net 2 34, the interior of the outer shell 33 is fixedly connected to a fan 35, and the interior of the outer shell 33 is fixedly connected to a mounting plate 36 The interior of the mounting plate 36 is fixedly connected with a semiconductor refrigeration sheet 37, the cooling surface of the semiconductor refrigeration sheet 37 is in contact with the outer wall of the fan 35, the heating surface of the semiconductor refrigeration sheet 37 is fixedly connected with a heat dissipation fin 38, one end of the heat dissipation fin 38 is arranged on the outer wall of the shell 33, the interior of the head ring 1 is rotatably connected with a connector 41, the outer wall of the connector 41 is fixedly connected with an adjusting rod 42, the interior of the adjusting rod 42 is rotatably connected with an adjusting handle 46, the outer wall of the adjusting rod 42 is rotatably connected with an adjusting rod 2 43, the bottom end of the adjusting rod 2 43 is fixedly connected with a connector 2 44, the outer wall of the connector 2 44 is rotatably connected with a support block 45, and the outer wall of the support block 45 is fixedly connected with a base 47.

[0038] Specifically, the patient needs to sit on a special chair. After the patient sits down, pull the adjustment rod 2 43 to rotate the connecting head 2 44 on the support block 45. This step is to adjust the angle of the device to adapt to the patient's head. Next, turn the adjustment rod 1 42 to rotate the connecting head 1 41 inside the head ring 1.
