Description

Technical Field

[0001] This utility model specifically relates to a high-frequency magnetic field stimulator for the eye, belonging to the field of magnetic therapy technology. Background Technology

[0002] Magnetic eye stimulation (MEPS) is a treatment method that uses magnetic fields to stimulate the eyes, aiming to improve eye health and vision. This method uses the energy of the magnetic field to promote blood circulation in the eyes and relieve eye fatigue. It also has a positive intervention effect on some eye diseases.

[0003] Most existing ocular magnetic stimulators use magnets as actuators. For example, one existing ocular magnetic stimulator uses therapeutic magnetic blocks to provide the magnetic field. Because the magnetic field on the surface of the magnet is basically fixed, the magnetic field strength of the actuator cannot be adjusted; at most, it can only be adjusted by the distance, which is inconvenient. To adjust the magnetic field, one existing ocular magnetic stimulator uses copper wire wound into a stimulation coil, with a maximum magnetic field strength of 1T. However, the controller of this strong magnet directly uses a TMS (transcranial magnetic stimulation) device, resulting in a bulky main unit and high output energy, causing severe heating of the magnetic stimulator coil, thus limiting the maximum frequency to 200Hz.

[0038] In view of the shortcomings of the prior art, the inventor of this case, through long-term research and extensive practice, has proposed the technical solution of this utility model. The following will further explain and illustrate the technical solution, its implementation process and principle in conjunction with the accompanying drawings and specific implementation examples.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model. Example

[0040] Please see Figure 1 As shown in Figure 4, a high-frequency magnetic field stimulator for the eye includes a wearable device, six magnetic stimulators 5, and a controller 8. The wearable device can be worn on the head of a human body. The six magnetic stimulators 5 are arranged in parallel and spaced apart to form a ring-shaped magnetic stimulator. The magnetic stimulator is fixedly mounted on the wearable device. The six magnetic stimulators 5 are respectively connected to the controller 8. The controller 8 is used to independently provide current to the magnetic stimulators 5, and to make the magnetic stimulators 5 generate a first magnetic field and a second magnetic field between adjacent magnetic stimulators, so that the magnetic field acts on the eyes and brain of the human body, thereby realizing magnetic stimulation.

[0041] When the wearable device is worn on the human head, the magnetic field direction of the magnetic field generated by the magnetic stimulation actuator 5 is parallel to the extension direction of the central axis of the human face, and the magnetic field lines pass through the human eye. Six magnetic stimulation actuators 5 can form an array so that multiple points around the eyes can receive magnetic stimulation at the same time.

[0042] In this embodiment, the wearable device includes a rigid headband 7 with a fixed posture and an adjustable telescopic strap 6. The two ends of the telescopic strap 6 are fixedly connected to the two ends of the headband 7, forming a ring-shaped wearable structure. Six magnetic stimulation actuators 5 are fixedly mounted on the headband 7. The size of the wearable structure can be changed by adjusting the length of the telescopic strap 6 to fit different body types. For example, the adjustable structure of the telescopic strap 6 is existing technology. For example, the telescopic strap 6 can be an elastic band or other stretchable structure. Alternatively, the telescopic strap 6 can be fixedly connected using a snap-fit ​​or similar structure, and the telescopic strap 6 can also be fixedly connected to the headband 7 using a snap-fit ​​or similar structure. In this embodiment, the six magnetic stimulation actuators 5 are distributed on the front side of the headband 7. The six magnetic stimulation actuators 5 can work simultaneously or sequentially, thereby producing a better magnetic stimulation effect.

[0043] In this embodiment, please refer to the following: Figure 2 , Figure 3 The magnetic stimulation actuator 5 includes a housing 26 and an iron core 24 and a conductive coil 25 encapsulated inside the housing 26. The iron core 24 is formed by stacking multiple layers of sheet metal. The conductive coil 25 is wound around the outside of the iron core 24 to form a reversible magnet. The housing 26 is a plastic shell, the iron core 24 is made of pure iron or an iron alloy, and the conductive coil 25 is enameled wire with an insulating layer. It should be noted that the conductive coil 25 is arranged around the axis of the iron core 24. For example, the outer diameter of the conductive coil 25 is 10 mm, the inner diameter is 5 mm, and the height is 20 mm. The magnetic field strength can also be changed by altering the size of the conductive coil 25, i.e., changing it to an outer diameter of 15 mm, an inner diameter of 10 mm, and a height of 20 mm. In this embodiment, the housings 26 of six magnetic stimulation actuators 5 are fixedly connected by plastic connectors to form a ring-shaped magnetic stimulation device.

[0044] like Figure 4a , Figure 4b As shown, when the magnetic stimulation device is placed around the eyes, six magnetic stimulation actuators 5 are distributed around the eyes. The central axes of the conductive coils 25 of the six magnetic stimulation actuators 5 are parallel and perpendicular to the human face. When the controller supplies current to the six magnetic stimulation actuators, the external magnetic field directions of the first magnetic field generated by two adjacent magnetic stimulation actuators 5 are opposite and perpendicular to the eyes / face. A second magnetic field is also generated between the ends of the same end of two adjacent magnetic stimulation actuators 5. The magnetic field direction of the second magnetic field intersects the external magnetic field direction of the first magnetic field and is parallel to the circumference of the annular structure of the magnetic stimulation device. The magnetic field lines of the first magnetic field and the second magnetic field pass through the eyes and brain of the human body.

[0045] In this embodiment, please refer to Figures 5-7The controller 8 includes a controller housing 1 and a switching circuit (module) 10 module, a drive module 11, and a power supply 9 encapsulated inside the controller housing 1. The switching circuit (module) 10 module is electrically connected to the drive module 11 and the power supply 9, respectively. The switching circuit (module) 10 module is electrically connected to the magnetic stimulation actuator 5 through a cable 4. The power supply 9 is used to provide DC power. The drive module 11 is used at least to control the conduction time of the switching circuit (module) 10 module by outputting waveform signals of different frequencies. The controller housing 1 is provided with a start / stop button 3 and an indicator light 2. After the power is turned on, pressing the start / stop button 3 will start magnetic stimulation therapy. Pressing the start / stop button 3 will stop the therapy device from working.

[0046] In this embodiment, please refer to the following: Figure 8 The drive module 11 outputs a PWM, maintaining a constant period for each PWM. Initially, the duty cycle is 0%. As time progresses, the duty cycle gradually increases, eventually reaching 50%. Then, as time progresses again, the duty cycle gradually decreases, eventually returning to 0%, thus achieving a set of sinusoidal wave outputs. After this control, the waveform acting on the load (magnetic stimulation actuator 5) becomes: the initial waveform amplitude is 0, the amplitude gradually increases until it reaches its maximum, and then gradually decreases until it returns to 0. An inductor L is added, with a suitable inductance value selected, to achieve voltage boosting, thereby increasing the magnetic field strength.

[0047] For details, please refer to the following document again. Figure 8 The switching circuit in this invention includes a MOSFET or IGBT, a device capable of high-frequency turn-on and turn-off. A magnetic stimulation actuator acts as a load, with one end connected to the power supply and the other end connected to the drain (D) of the MOSFET or the collector (C) of the IGBT. When the MOSFET or IGBT is turned on, the voltage applied to the magnetic stimulation actuator is the power supply voltage. To increase the voltage on the magnetic stimulation actuator, thereby increasing the magnetic field strength without changing the power supply voltage, an inductor is added to the load. One end of this inductor is connected to the power supply, and the other end is connected to the magnetic stimulation actuator in series. As is well known, an inductor, as an energy storage element, has a voltage boosting function. This means that when the MOSFET or IGBT is turned on, the voltage applied to the magnetic stimulation actuator can be approximately twice the power supply voltage, generating a stronger magnetic field to enhance the magnetic stimulation effect on the eye.

[0048] Specifically, the main functional element of the drive module 11 is a transistor. The drive module 11 may contain a single transistor or a push-pull circuit composed of multiple transistors. The conduction of the transistor is controlled by a pulse signal, thereby controlling the operation of the switching circuit (module) 10. Furthermore, the drive module 11 controls the conduction time of the switching circuit (module) 10 by outputting waveform signals of different frequencies, which can be low frequency or high frequency, thereby achieving different therapeutic effects.

[0049] In this embodiment, the power supply 9 includes a power supply circuit (module) 12, a switching power supply (module) 13, and an output circuit (module) 14. The switching power supply 13 is electrically connected to the power supply circuit 12 and the output circuit 14, respectively. The output circuit 14 is electrically connected to the switching circuit (module) 10 module. The switching power supply (module) 13 and the output circuit (module) 14 convert the AC power from the power supply circuit 12 into the DC power required by the power supply 9.

[0050] In this embodiment, please refer to Figure 7 The switching power supply (module) 13 includes a rectifier bridge 15, an input filter circuit 16, an RCD clamp circuit 17, a switching element 18, a high-frequency transformer 19, a rectifier diode 20, an output filter circuit 21, a feedback module 22, and a driver chip 23. The rectifier bridge 15 is connected to the input filter circuit 16. One end of the input filter circuit 16 is connected to one end of the primary side of the RCD clamp circuit 17 and the other end of the primary side of the high-frequency transformer 19. The other end of the RCD clamp circuit 17 and the other end of the primary side of the high-frequency transformer 19 are connected to the switching element 18. One end of the secondary side of the high-frequency transformer 19 is connected to the rectifier diode 20, and the other end of the secondary side of the high-frequency transformer 19 is grounded. The rectifier diode 20 is connected to the output filter circuit 21. One end of the output filter circuit 21 is connected to one end of the feedback module 22, and the other end of the feedback module 22 is connected to the driver chip 23. The rectifier bridge 15 and the input filter circuit 16 convert the AC power input from the previous stage into DC power.

[0051] Specifically, the RCD clamping circuit 17 includes a circuit composed of resistors, capacitors, and diodes, which is used to suppress resonant voltage spikes and protect the switching element 18 from damage. The switching element 18 and the high-frequency transformer 19 are the core components of the switching power supply 13. By controlling the on / off state of the switching element 18, circuit energy is conducted from the primary side to the secondary side of the high-frequency transformer 19, achieving energy transfer while simultaneously reducing voltage. The high-frequency transformer 19 reduces the input voltage to a value lower than the input voltage. The rectifier diode 20 and the output filter circuit 21 convert the AC input from the previous stage into DC. The feedback module 22 detects the voltage value at the output filter circuit 21 and transmits a signal to the driver chip 23 according to the load. The driver chip 23 drives the switching element 18 at a certain frequency based on the transmission signal provided by the feedback module 22. When the load is heavy, the driver chip 23 increases the driving frequency to drive the switching element 18; conversely, when the load is light, the driver chip 23 decreases the driving frequency to drive the switching element 18, ultimately maintaining the stability of the voltage value at the output filter circuit 21.

[0052] In this embodiment, the power supply circuit is connected to the AC mains power, the output filter circuit is connected to the switching circuit, and the switching circuit is connected to the conductive coil of the magnetic stimulator actuator. With this structure, the AC mains power is used to power the switching power supply, which transforms the AC mains power into DC power that is lower than the AC mains power. Finally, the magnetic stimulator actuator is discharged by switching the switching circuit on and off. After the conductive coil is energized, a magnetic field is generated, and the peak value of the magnetic field is located at the end face of the iron core of the magnetic stimulator actuator. The switching circuit includes switching devices such as MOSFETs or IGBTs with high-frequency switching functions. The input filter circuit includes a circuit with capacitors as the main components or a circuit composed of capacitors and inductors. The output filter circuit includes a circuit with capacitors as the main components or a circuit composed of capacitors and inductors. The feedback module includes an optocoupler as the main component and its related circuits.

[0053] In this embodiment, the controller further includes an operation control module, which includes a drive module connected to the switching circuit. With this structure, the drive module controls the on and off time of the switching circuit by outputting waveforms of different frequencies, thereby flexibly adjusting the method and intensity of magnetic stimulation.

[0054] The eye magnetic stimulator provided in this embodiment of the invention is powered by DC power supply. By controlling the conduction frequency of the switching element, a voltage pulse of a certain frequency is generated, which causes the conductive coil to generate a magnetic field of a certain frequency after being energized, thereby achieving the effect of magnetic stimulation.

[0055] In this embodiment, when performing eye care using the ophthalmic high-frequency magnetic field stimulator, the ophthalmic high-frequency magnetic field stimulator is worn on the head, with the magnetic stimulation actuator positioned in front of the eyes. When the magnetic stimulation device is placed around the eyes, six magnetic stimulation actuators 5 are arranged in a ring around the eyes. The central axes of the conductive coils 25 of the six magnetic stimulation actuators 5 are parallel and perpendicular to the human face. A controller applies current to the magnetic stimulation actuators.
