DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0037] The embodiment of the present invention provides a head-mounted neural stimulator capable of delaying and improving cognitive function, comprising a head-mounted earmuff 1 for being worn on a patient's head, wherein a 808nm infrared light therapy device 2 for stimulating the patient's brain and having an adjustable angle is provided on one side of the middle part of the head-mounted earmuff 1, wherein the 808nm infrared light therapy device 2 stimulates the patient's head by irradiating the forehead and both sides of the patient with infrared LED light, wherein the 808nm infrared light therapy device 2 is provided with an eye protection device 3 for covering the patient's eyes, wherein a 40Hz light flashing device 4 for visually stimulating the patient's eyes is provided inside the eye protection device 3, wherein a placement hole 11 is provided on the inner wall of the lower end of the middle part of the head-mounted earmuff 1, and an iron sheet is provided inside the placement hole 11, wherein a nasal stimulation device 5 for stimulating the brain by inhaling fragrance through the patient's nose is provided at the lower end of the eye protection device 3, and a 40Hz audio generator 6 for advanced bone conduction of the patient's ears is provided inside both sides of the head-mounted earmuff 1;

[0038] This device can stimulate the patient's brain through 808nm infrared light therapy, 40Hz light flashes for eye visual stimulation, 40Hz audio waves accurately transmitted by bone conduction, transcranial magnetic stimulation, and nasal olfactory stimulation to promote the brain's gamma wave activity, improve cognitive performance, emotional balance, and overall mental health. Different stimulation methods can achieve different stimulation effects, enhance the clearing function of the brain lymphatic system, and optimize the patient's brain performance, sleep, and cognition.

[0039] This device stimulates the patient's brain through 808nm infrared light therapy, 40Hz light flashes for eye visual stimulation, 40Hz audio waves precisely transmitted through bone conduction, transcranial magnetic stimulation, and transnasal olfactory stimulation. These methods can be combined and started synchronously to stimulate the patient's brain to obtain different stimulation effects, which can promote blood circulation and neuron activation.

[0040] This device is connected to an intelligent computer device, which is also the intelligent computer device used by the traditional transcranial navigation magnetic therapy device. After the patient wears the head-mounted earmuffs 1, he can use the remote control to achieve brain stimulation. After the stimulation is completed, the data will be transmitted to the intelligent computer device for subsequent viewing. It can also be placed by others to perform brain stimulation operations;

[0041] This device is suitable for patients with depression, schizophrenia, insomnia, obsessive-compulsive disorder, mania, anxiety, post-traumatic stress disorder, Parkinson's disease, epilepsy, neuropathic pain, neurological tinnitus, stroke, spinal cord injury and complications, peripheral nerve injury, Alzheimer's disease, dystonia, sexual dysfunction, cerebral palsy, autism, epilepsy, attention deficit hyperactivity disorder (ADHD), tics, Internet addiction, drug addiction, smoking cessation, alcohol addiction, etc., and can achieve corresponding effects through different ways of brain stimulation.

[0042] The device realizes multi-sensory fusion training to promote neuron regeneration, thereby improving cognitive function and preventing functional degradation; and solves the problem of single stimulation in existing neural stimulation devices.

[0043] The light stimulation component 22 in the present device is detachable. When the light stimulation component 22 and the lamps in the two 40Hz light flashing devices 4 are damaged and need to be replaced, the adjusting nut is rotated and disengaged from the adjusting bolt 212. At this time, the adjusting bolt 212 can be pulled out from the two fixing blocks 211. At this time, the light stimulation component 22 completes the disassembly operation. The whole process is relatively simple. After the light stimulation component 22 is disassembled, the two 40Hz light flashing devices 4 will also be removed. The corresponding damaged lamps can be replaced, which increases the service life of the present device.

[0044] Preferably, the earmuffs on both sides of the head-mounted earmuff 1 are both openable in the middle, and the connection mode is connected by magnetic attraction. The head-mounted earmuff 1 is provided with a flexible sponge pad 12 at the position where the head-mounted earmuff 1 contacts the head. The placement holes 11 are provided with a plurality of holes, and the plurality of placement holes 11 are irregularly arranged inside the lower end of the head-mounted earmuff 1. The flexible sponge pad 12 is provided with stimulation holes 13 corresponding to the plurality of placement holes 11. The plurality of placement holes 11 are provided with iron sheets, and the plurality of iron sheets can be adsorbed by magnets.

[0045] The earmuffs on both sides of the head-mounted earmuffs 1 are both openable in the middle and are connected by magnetic attraction, so that the advanced bone conduction 40Hz audio generator 6 can be worn easily;

[0046] When stimulating the patient's head through transcranial magnetic stimulation, the magnet for stimulation can be placed in the corresponding placement hole 11 according to the actual situation, and the magnet and the iron sheet can be attracted to each other. Then, the head-mounted earmuff 1 is worn. After wearing, the patient's brain is stimulated by the magnet. The stimulation principle is to use a strong magnetic field to generate a small current, thereby stimulating the nerve tissue on the surface of the brain. Transcranial magnetic stimulation includes a powerful permanent magnet and a coil, which are installed on the scalp of a patient. When the doctor passes an external current to the coil, it will generate a small magnetic field on the skin, which corresponds to another coil on the patient's scalp. When the distance between the two coils is close enough, they will interact to form a very small magnetic field. This tiny The magnetic field can pass through the scalp and produce a magnetic stimulation in the patient's cerebral cortex. The effect of this stimulation depends on the intensity and time of the stimulation, as well as the location and number of stimulations. It can change the membrane potential of neurons, neuronal activity patterns, synaptic plasticity and neural network connections, thereby affecting a variety of neurological diseases and symptoms. The advantages of transcranial magnetic stimulation of this device are its non-invasiveness and reversibility, which means that it can be safely applied to the human body and can treat many neurological diseases and symptoms without the need for long-term use of drugs. According to the above, this device can use the required number and arrangement of magnets according to actual conditions. It only needs to attract the first magnet to the iron sheet inside the corresponding placement hole 11 to stimulate the patient's brain to varying degrees.

[0047] Preferably, the 808nm infrared light therapy device 2 includes an angle adjustment component 21 and a light stimulation component 22, the angle adjustment component 21 is arranged on the side of the middle part of the head-mounted earmuff 1, and the light stimulation component 22 is arranged on the angle adjustment component 21, the angle adjustment component 21 includes a fixed block 211, an adjusting bolt 212, an adjusting nut 213 and an adjusting plate 214, two fixed blocks 211 are provided, and the two fixed blocks 211 are symmetrically arranged on the side of the middle part of the head-mounted earmuff 1, the end of the adjusting bolt 212 passes through the other fixed block 211 from one side of the fixed block 211, the end of the adjusting bolt 212 is provided with an external thread, the middle part of the adjusting bolt 212 has no thread, the middle part of the adjusting bolt 212 is located between the two fixed blocks 211 and is rotatably connected, the adjusting nut 213 is sleeved on the end of the adjusting bolt 212 and is threadedly connected, and the head end of the adjusting plate 214 is sleeved on the adjusting bolt The middle part of 212 is fixedly connected, the arc-shaped setting of the adjustment plate 214 and the angle of the arc is consistent with the arc angle from the top of the head to the eye of a traditional adult, the light stimulation component 22 includes a main 808nm infrared light 221 and a slave 808nm infrared light 222, the main 808nm infrared light 221 is set at the lower end of the adjustment plate 214, and the slave 808nm infrared light 222 is provided with two, the two slave 808nm infrared light lamps 222 are symmetrically arranged on both sides of the main 808nm infrared light lamp 221, and the connection method is the same as the balance arm principle in the traditional shadowless lamp, which can be adjusted in angle and has a certain supporting function, the main 808nm infrared light 221 and the two slave 808nm infrared light lamps 222 all adopt high-brightness and low-heat infrared LED matrices, and the main 808nm infrared light 221 and the two slave 808nm infrared light lamps 222 are arranged in a uniform manner;

[0048] When stimulating the patient's head by irradiating the 808nm infrared LED light, the head-mounted earmuff 1 is worn, and then, according to the required patient's head shape, forehead, and the position of the temples on both sides of the forehead, the adjusting nut is rotated to change the adjusting bolt 212 from a fixed state to a rotatable state, and the adjusting bolt 212 is rotated by a certain angle to drive the light stimulation component 22 to adjust the angle, so that the main 808nm infrared light 221 is just facing the patient's forehead. At this time, the adjusting nut 213 is rotated to lock and fix the adjusting bolt 212, and then, the two slave 808nm infrared light lamps 222 are bent and adjusted to the corresponding direction with the temples on both sides of the forehead. At this time, the light stimulation component 22 is activated to stimulate the patient's brain through the 808nm infrared LED light;

[0049] 808nm infrared LED light is a non-invasive therapy for head-mounted neurostimulators that can delay and improve cognitive function. Its working principle is based on the biophotonics effect. Biophotonics is an interdisciplinary field that involves knowledge from multiple disciplines such as biology, physics, and engineering. Photosensitization is an important branch. When photons enter biological tissues, they are absorbed and scattered, and can stimulate electronic transitions in biological molecules. In some cases, this phenomenon can lead to chemical reactions in biological tissues or changes in physiological processes. During the irradiation of 808nm infrared LED light, photons are used to activate photoreceptors in cells, such as hemoglobin, cytochrome P450, endogenous fluorophores, etc., thereby triggering a series of photochemical and photoelectric processes. This effect will cause a series of biochemical changes, including the opening and closing of ion channels, the activation and inactivation of enzymes, the generation and clearance of metabolites, the signal transduction and communication of cells, etc., which in turn affect the behavior of cells and tissues. Since the wavelength of 808nm infrared LED light matches the biological absorption spectrum of the human body, it can effectively penetrate the skin and tissues and activate deep biological molecules, thereby affecting the organisms and tissues throughout the body. In general, the irradiation method of 808nm infrared LED light is to stimulate the electronic transition of biological molecules through the absorption and scattering of photons, thereby triggering a series of biochemical and photoelectric processes, and ultimately affecting the behavior of cells and tissues.

[0050] Preferably, the eye protection device 3 includes a support block 31, a main rod 32, a slave rod 33, a bolt knob 34, a connecting block 35 and an eye protection mask 36, wherein the support block 31 is arranged on the upper surface of the adjustment plate 214, the main rod 32 is arranged on the support block 31, the slave rod 33 is arranged inside the main rod 32 and is arranged to slide up and down, the outside of the main rod 32 at the end of the bolt knob 34 passes through the inside and contacts the upper surface of the slave rod 33, and the connecting block 35 is arranged at the lower end of the slave rod 33. The eye protection mask 36 is arranged on the inner side of the connecting block 35, and two grooves 361 are symmetrically arranged inside the eye protection mask 36. Two 40Hz light flashing devices 4 are provided, and the two 40Hz light flashing devices 4 are respectively arranged in the corresponding grooves 361. The two 40Hz light flashing devices 4 both use a 40Hz light flashing system to integrate a safe LED light source, and flash subtly at a frequency of 40Hz, which is synchronized with the gamma wave frequency in the electroencephalogram (EEG) to enhance the coordination between brain networks;

[0051] During the stimulation of the patient's head by irradiation with 808nm infrared LED light, the bolt knob 34 can be rotated first, so that the end of the bolt knob 34 is out of the state of abutment with the upper surface of the slave rod 33. At this time, the slave rod 33 is stretched to adjust the position of the eye protection mask 36 and the patient's eyes to a fitting state. Then, the bolt knob 34 is rotated to make the end of the knob bolt abut against the upper surface of the slave rod 33 again to form a fixation, and the patient's eyes can be shielded by the eye protection mask 36 to avoid the occurrence of eye discomfort of the patient during the irradiation of the 808nm infrared LED light.

[0052] During the process of the eye protection mask 36 shielding the patient's eyes, the patient's brain can be stimulated by two 40Hz light flickering devices 4. The stimulation principle is light flickering stimulation generated at a frequency of 40 Hz. This stimulation is usually used in functional magnetic resonance imaging (fMRI) to record brain activity patterns. Specifically, 40 Hz light flickering stimulation is a head-mounted neural stimulator interference technology based on electroencephalogram (EEG) that can delay and improve cognitive functions. Electroencephalogram (EEG) is a head-mounted neural stimulator non-invasive detection technology that records brain electrical activity. It can detect neuronal discharge activities in different areas of the brain and the brain's response to external stimuli. However, EEG signals are affected by many factors, such as muscle movement, eye movement, eye movement, irregular discharge of the visual cortex, etc. In order to reduce the impact of these factors, researchers have developed some technologies to improve the quality of EEG signals. Light flickering technology is an artificial interference technology widely used in EEG research. In this technique, researchers present subjects with a steady background light source while randomly, briefly, and periodically switching brightness and color. These light flicker stimuli are thought to be brief, weak, desensitizing stimuli that have no significant effect on brain function. However, in fact, studies have shown that these light flicker stimuli can cause changes in the brain's electrical activity. In 40 Hz light flicker brain stimulation, the frequency of the light stimulation is similar to the human perception frequency, so it does not attract people's attention or interfere. This light flicker stimulation is mainly used to interfere with the noise in the EEG signal from the eyes, muscles, and other external sources, thereby improving the quality of the EEG signal. In general, 40 Hz light flicker brain stimulation is an EEG-based head-mounted neurostimulator interference technology that can delay and improve cognitive function. It is used to reduce noise in EEG signals and improve the quality of EEG signals.

[0053] Preferably, the nasal stimulation device 5 comprises a nasal connection block 51 and a nasal placement tube 52. The nasal connection block 51 is arranged at the lower end of the eye protection mask 36 and is inclined. The inclination angle is consistent with the inclination angle from the eyes to the highest point of the nose of an adult. Two nasal placement tubes 52 are provided. The two nasal placement tubes 52 are symmetrically arranged at the end of the back connection block. The ends of the two nasal placement tubes 52, that is, facing the patient's nose, are provided with a plurality of odor dispersing holes 53 connected to the inside of the corresponding nasal placement tubes 52. The head ends of the two nasal placement tubes 52 are provided with covers 54.

[0054] When stimulating the patient's head through nasal olfactory stimulation, the two nose placement tubes 52 and the lids 54 are opened, and the same odor substances or different odor substances can be placed in them. The corresponding lids 54 are closed. At this time, the odor substances are inhaled into the nose by the patient through the corresponding odor emission holes 53 to achieve stimulation. The principle of nasal olfactory stimulation is that nasal olfactory stimulation refers to the process of different odor substances acting on the human nose, thereby causing brain nerve reactions. This stimulation is somewhat similar to taste stimulation, but because the odor stimulation mainly stimulates the olfactory cortex located in the limbic system of the brain, rather than the taste cortex, they will cause different cognitive and emotional reactions. When people are exposed to a new odor substance that can delay and improve cognitive function, this substance will first be inhaled into the nasal cavity, and then the odor molecules will bind to the odor receptors on the mucosa in the nasal cavity, causing a chemical reaction, and finally transmitting the signal to the olfactory cortex of the limbic system of the brain. This process is called odor recognition. In the olfactory cortex, odor information is processed into meaningful features, such as the intensity, duration, and category of the odor. This information is used to help us make judgments in our daily lives, such as determining whether something is familiar or whether we should buy a product. When we are exposed to a new odorant, the substance is classified and stored in memory so that we can quickly recognize it in future exposure. This process is called olfactory memory. In general, olfactory stimulation of the nose causes neural responses in the brain's limbic system through the inhalation of odor molecules and the activation of odor receptors, and further triggers related cognitive and emotional responses.

The smart computer device is the same as the smart computer device used in the traditional transcranial navigation magnetic therapy device.

The 808nm infrared light therapy device 2, the two 40Hz light flashing devices 4 and the two 40Hz audio generators 6 use the same Bluetooth connection system and can be started and shut down asynchronously. The smart computer device is connected to a remote control via Bluetooth.

[0056] When using two 40Hz audio generators 6 for advanced bone conduction brain stimulation, two 40Hz audio generators 6 are connected to Bluetooth, and high-frequency mechanical vibrations are transmitted to the brain through the skull, thereby intervening in brain activity. This technology involves multiple disciplines, including biomechanics, material science, and electronic engineering. The following introduces the theoretical basis and some implementation principles of this technology.

[0057] Bone conduction: Bone conduction is a method of sound transmission that transmits the vibration of an object directly to the bone and soft tissue structure. When an object vibrates, its energy is directly transferred to the surrounding objects. This method of energy transfer makes bone conduction an effective way to transmit sound. In advanced bone conduction brain stimulation, the vibrating skull can directly transmit the vibration of the brain bones, converting mechanical energy into neural signals, thereby affecting brain activity;

[0058] Vibration of headed ermosal (HB): When the head is subjected to appropriate vibration, the space between the skull and the bones inside the skull can be used as a sound transmission medium to delay and improve cognitive function, transmitting the vibration force to the skull and then from the skull to the brain. Skull vibration can cause changes in intracranial pressure, thereby affecting the brain tissue inside the skull, especially the cerebral cortex, white matter and ventricles;

[0059] Brain neural response: When the head is subjected to appropriate vibration, this vibration can stimulate specific areas located in the brain's limbic system, such as the prefrontal lobe, parietal lobe, and temporal lobe, thereby causing a series of neural responses, including emotional response, concentration, memory enhancement, etc.

[0060] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
