Technical Field

[0001] This invention relates to the field of transcranial magnetic stimulation (TMS) instruments, and more particularly to a DC pulse transcranial magnetic sleep apnea device and its automatic high-low frequency switching method. Background Technology

[0002] Transcranial magnetic stimulation (TMS) is a physical therapy based on Faraday's law of electromagnetic induction. It uses magnetic fields to non-invasively stimulate brain neurons, generating minute currents through electromagnetic induction to regulate neuronal excitability and restore the balance between excitation and inhibition in the brain. TMS techniques include single-pulse, double-pulse, and repetitive stimulation (rTMS). As a non-invasive neuromodulation method, TMS has shown significant effectiveness in recent years in the treatment of mental illnesses such as depression and anxiety, as well as in stroke rehabilitation and cognitive function improvement. With increasing market demand, numerous TMS therapy devices have emerged both domestically and internationally.

[0003] Currently available transcranial magnetic stimulation (TMS) devices all use alternating magnetic fields generated by alternating current. These devices are large, expensive, and used primarily in hospitals. Each treatment requires payment, is time-consuming, wastes medical resources, and drains medical insurance funds. There are also small, home-use head-mounted TMS devices, but these are complex to use and difficult to promote. Summary of the Invention

By changing AC transcranial magnetic stimulation to DC transcranial magnetic stimulation, it achieves small size, safety, simple use, suitability for home use, low price, and is conducive to popularization.

[0005] A DC pulse transcranial magnetic sleep apnea device includes a main body and a coil body disposed within the main body. The device also includes a DC pulse generator. The main body is a pillow, and the coil body includes multiple coils. The pillow includes a base and a mask, which are assembled into a pillow-shaped structure. The multiple coils are respectively sandwiched between the base and the mask, spaced apart and arranged according to multiple lying positions. Each coil corresponds to a specific brain position in a lying position. The multiple coils are connected to the DC pulse generator via wires. The DC pulse generator outputs pulsed magnetic fields of corresponding frequencies to each coil. At least one coil outputs a high-frequency pulsed magnetic field, and at least one coil outputs a low-frequency pulsed magnetic field. Each pulsed magnetic field is designed to non-invasively penetrate the skull to act on functional areas of the cerebral cortex, and each pulsed magnetic field emits a unipolar positive pulse signal.

[0006] Specifically, the plurality of coil bodies include a first coil, a second coil, and a third coil; the first coil is located at the head position when lying flat, the second coil is positioned to act on the right brain position when in a second predetermined lying position, and the third coil is positioned to act on the left brain position when in a third predetermined lying position; the DC pulser outputs a first pulse magnetic field of a first frequency to the first coil, the DC pulser outputs a second pulse magnetic field of a second frequency to the second coil, and the DC pulser outputs a third pulse magnetic field of a third frequency to the third coil.

[0007] Furthermore, the low-frequency pulsed magnetic field is configured to enhance the secretion of GABA in the brain and inhibit excessive excitation of the cortex, while the high-frequency pulsed magnetic field is configured to enhance the secretion of serotonin and dopamine and excite the cerebral cortex.

[0008] Furthermore, the first coil is positioned at the head when the human body is lying flat, the second coil is positioned corresponding to the right brain when the human body is lying on its right side, and the third coil is positioned corresponding to the left brain when the human body is lying on its left side.

[0009] Specifically, the first coil is located in the middle of the interior of the pillow body, and the second coil and the third coil are located on both sides of the first coil. The second coil and the third coil are symmetrically distributed on both sides of the first coil with the axis of symmetry as the axis of symmetry. The first coil, the second coil and the third coil are arranged in a triangular shape.

[0010] Specifically, the inner side of the mask or base is provided with three coil grooves, which respectively accommodate the first coil, the second coil, and the third coil; the inner side of the mask or base is also provided with a wiring groove for setting up cables connecting each coil to the DC pulser; the DC pulser is provided with a circuit board, on which a control chip is provided, and the control chip has at least three pulse output pins, each pulse output pin being connected to the corresponding coil through a circuit and a corresponding wire, and multiple wires being bundled together to form an integrated cable.

[0011] Preferably, each of the pulsed magnetic fields is a positive polarity square wave pulse, and the pulse waveform of each pulsed magnetic field is above the positive axis. The second pulsed magnetic field is a low-frequency pulsed square wave with a frequency of less than 1 Hz, and the third pulsed magnetic field is a high-frequency pulsed square wave with a frequency of 5 Hz to 10 Hz.

[0012] Furthermore, the inner side of the base or the mask has a concave cavity, and the bottom of the concave cavity is provided with three coil grooves, which respectively accommodate the first coil, the second coil, and the third coil; the second coil and the third coil are respectively spaced apart from the first coil by a predetermined distance, the predetermined distance being 20-40cm, and the thickness of the base and the mask is 3-15cm.

[0013] Furthermore, a method for automatic switching between high and low frequency DC pulse transcranial magnetic stimulation (TMS) is provided, applicable to the DC pulse TMS sleep aid described above. This method includes the following steps: The multiple coils are controlled within their respective frequency ranges; Based on the user's mental state, the appropriate lying position is selected. When lying flat, at least one coil is turned on to provide a low-frequency pulsed magnetic field. Through the low-frequency pulsed magnetic field, a unipolar positive pulse signal acts on the human brain to continuously and unipolarly stimulate the nerve cells of the cerebral cortex, release neurotransmitters, and help to fall asleep. After a predetermined period of action at the first frequency or according to the user's mental state, after the user switches to the second lying position, the low-frequency pulse magnetic field of another coil corresponding to the right brain position of the second lying position acts on the right brain of the human body with a unipolar positive pulse signal. Based on the user's mental state, a third predetermined lying position is selected. A high-frequency pulse magnetic field is emitted by another coil corresponding to the left brain position of the third lying position.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 5This illustration shows an embodiment of a DC pulse transcranial magnetic sleep apnea device 10, comprising a main body and a coil body disposed within the main body. The DC pulse transcranial magnetic sleep apnea device 10 further includes a DC pulse generator 20. The main body is a pillow body 11, and the coil body includes multiple coils. The pillow body 11 includes a base 12 and a mask 15, which are assembled into an integral pillow-shaped structure. The multiple coils are respectively sandwiched between the base 12 and the mask 15, and are spaced apart and arranged according to multiple lying positions. Each coil corresponds to a specific brain position in a lying position. The multiple coils are electrically connected to the DC pulse generator 20, which outputs pulsed magnetic fields of corresponding frequencies to each coil. At least one coil outputs a high-frequency pulsed magnetic field, and at least one coil outputs a low-frequency pulsed magnetic field. Each pulsed magnetic field is designed to non-invasively penetrate the skull to act on functional areas of the cerebral cortex, and each pulsed magnetic field emits a unipolar positive pulse signal.

[0023] Specifically, such as Figure 1 As shown, the pillow body 11 has three functional positions 13 visible on its exterior, each containing a corresponding coil. The functional positions 13 facilitate user identification of the operating location, serving as an identifier. The multiple coil bodies include a first coil 21, a second coil 22, and a third coil 23; the first coil 21 is located at the head position when lying flat, the second coil 22 is positioned to act on the right brain in a second predetermined lying position, and the third coil 23 is positioned to act on the left brain in a third predetermined lying position; the DC pulse generator 20 outputs a first pulse magnetic field of a first frequency to the first coil 21, a second pulse magnetic field of a second frequency to the second coil 22, and a third pulse magnetic field of a third frequency to the third coil 23.

[0024] In some specific implementations, the pulsed magnetic field is configured to stimulate neurons in the cerebral cortex with a single positive DC pulsed magnetic field to release neurotransmitters and aid in falling asleep. Transcranial magnetic stimulation (TMS) is a nationally certified green physical therapy technology that primarily uses a proprietary frequency pulsed magnetic field to non-invasively penetrate the skull and act on the neural regions of the cerebral cortex to balance excitatory and inhibitory neurotransmitters.

[0025] Specifically, the low-frequency pulsed magnetic field is configured to enhance GABA secretion in the brain and inhibit cortical over-excitation. By enhancing GABA secretion and inhibiting cortical over-excitation, it quickly calms and relaxes the mind, improves difficulty falling asleep, light sleep, frequent awakenings at night, prolongs deep sleep cycles, and relieves tension, anxiety, and distracting thoughts. The high-frequency pulsed magnetic field is configured to enhance the secretion of serotonin and dopamine in brain cells and promote cortical excitation.

[0026] Furthermore, the first coil 21 is positioned at the head when the human body is lying flat, the second coil 22 is positioned corresponding to the right brain when the human body is lying on its right side, and the third coil 23 is positioned corresponding to the left brain when the human body is lying on its left side.

[0027] Specifically, the first coil 21 is located in the middle of the interior of the pillow body 11, and the second coil 22 and the third coil 23 are located on both sides of the first coil 21. The second coil 22 and the third coil 23 are symmetrically distributed on both sides of the first coil 21 with the axis of symmetry as the axis of symmetry. The first coil 21, the second coil 22 and the third coil 23 are arranged in a triangular shape.

[0028] Furthermore, such as Figure 4 As shown, the inner side of the mask 15 or base 12 is provided with three coil grooves 17. The example shown is that the coil grooves 17 are provided on the inner side of the mask 15. The three coil grooves 17 are respectively used to install the first coil 21, the second coil 22 and the third coil 23. The inner side of the mask 15 or base 12 is also provided with a wiring groove for providing cables 28 connecting each coil to the DC pulse generator 20. The DC pulse generator 20 is provided with a circuit board 26, and the circuit board 26 is provided with a control chip 25. The control chip 25 has at least three pulse output pins 18. Each pulse output pin 18 is connected to the corresponding coil through a circuit and a corresponding wire 19. Multiple wires 19 are bundled together to form a cable 28.

[0029] In some preferred embodiments, each of the pulsed magnetic fields is a positive polarity square wave pulse, with the pulse waveform of each pulsed magnetic field above the positive axis. The second pulsed magnetic field is a low-frequency pulsed square wave with a frequency less than 1 Hz, and the third pulsed magnetic field is a high-frequency pulsed square wave with a frequency of 5 Hz to 10 Hz. Studies have found that high-frequency transcranial magnetic stimulation can activate brain nerve cells to release neurotransmitters, improve low mood, decreased energy, and loss of interest, resolve early awakening and sleep disorders caused by depression, and break the vicious cycle of sleep and mood.

[0030] In some specific embodiments, the inner surface of the base 12 or the face mask 15 has a concave cavity, and the bottom of the concave cavity is provided with three coil grooves 17. The three coil grooves 17 are respectively fitted with the first coil 21, the second coil 22, and the third coil 23. The second coil 22 and the third coil 23 are respectively spaced from the first coil 21 by a predetermined distance, the predetermined distance being 20-40cm. The thickness of the base 12 and the face mask 15 is 3-15cm. Figure 1 and Figure 2 , Figure 5As shown, the pillow body 11 also has a neck support 16 for supporting the user's neck during sleep.

[0031] like Figure 5 As shown, the DC pulse generator 20 may also contain a battery 27. The battery can be a rechargeable battery or other DC power source, preferably a 12V or 24V battery. A battery adapter or conversion module may also be provided. After connecting to AC power, the adapter / conversion module will step down the voltage and charge the battery 27. In use, the battery 27 directly supplies power, making it safer and more reliable.

[0032] In another aspect of this invention, a method for automatic switching between high and low frequency DC pulse transcranial magnetic stimulation (TMS) is provided, applicable to the DC pulse TMS sleep aid 10 described above. This method can also be considered as a method of using the aforementioned DC pulse TMS sleep aid. The method includes the following steps: Step S10 involves adjusting the multiple coils within their respective frequency ranges. For example, in the above embodiment, three coils are used: the control chip 25 outputs a low-frequency pulse signal to the first coil 21 to cause it to emit a first low-frequency pulse magnetic field; it outputs a second low-frequency pulse signal to the second coil 22 to cause it to emit a second low-frequency pulse magnetic field; and it outputs a high-frequency pulse signal to the third coil 23 to cause it to emit a high-frequency pulse magnetic field. Of course, in practical applications, the high-frequency or low-frequency components of the three coils can be replaced to meet the user's actual needs.

[0033] Step S20: Based on the user's mental state, a suitable lying position is selected. In the supine position, at least one coil is activated to provide a low-frequency pulsed magnetic field. This low-frequency pulsed magnetic field acts on the human brain with a unipolar positive pulse signal, continuously and singly stimulating the nerve cells of the cerebral cortex to release neurotransmitters and aid in falling asleep. In the above embodiment, when the supine position is adopted, the first low-frequency pulsed magnetic field is emitted through the first coil 21 to act on the human brain, specifically the back of the head. Through low-frequency pulsed transcranial magnetic stimulation, difficulties falling asleep, light sleep, and frequent awakenings at night are improved, deep sleep cycles are prolonged, and tension, anxiety, and distracting thoughts are relieved.

[0034] In step S30, after a predetermined period of action at the first frequency, or as selected based on the user's mental state, after the user switches to a second lying position, a low-frequency pulsed magnetic field from another coil corresponding to the right brain location in the second lying position acts on the right brain with a unipolar positive pulse signal. This usually occurs when the user, after the predetermined time in step S20 (e.g., 10-20 minutes), still cannot fall asleep, and then turns to their right side. This allows the low-frequency pulsed transcranial magnetic stimulation from the second coil 22 to further stimulate the neurons in the right brain, increasing GABA secretion, inhibiting cortical over-excitation, and further deepening sleep.

[0035] Step S40: Based on the user's mental state, a third predetermined lying position is selected. A high-frequency pulsed magnetic field is emitted through another coil corresponding to the left brain position of this third lying position. This high-frequency pulsed magnetic field acts on the left brain with a unipolar positive pulse signal. This step is primarily for patients with depression or those who need to increase alertness and improve mental state upon waking in the morning. Specifically, the high-frequency pulsed transcranial magnetic stimulation emitted by the third coil 23 improves low mood, decreased energy, and loss of interest, resolves early awakening and sleep disturbances caused by depression, and breaks the vicious cycle of sleep and mood.

[0036] Therefore, based on actual needs, it can freely and smoothly switch between high and low frequency transcranial magnetic stimulation of the corresponding coil without any obstruction or unnecessary operation. It is convenient for daily use, small in size, safe, simple to use, suitable for home use, inexpensive, and conducive to popularization. This sleep aid is also portable and can be used at home or while traveling, making it suitable for a wide range of people and not limited to fixed locations such as hospitals.

[0037] It should be noted that the present invention is not limited to the above-described embodiments. Based on the inventive spirit of the present invention, those skilled in the art can make other changes, and these changes made in accordance with the inventive spirit of the present invention should be included within the scope of protection claimed by the present invention.
