Description

Technical Field

[0001] The present invention relates to the technical field of intelligent health care, and particularly relates to an intelligent comb. Background Art

[0002] Combs have been widely used by people since a very early time. Its history can be traced back to more than 6,000 years ago. From the perspective of traditional Chinese medicine clinical practice, combing hair is not only a daily care behavior, but also an important means to regulate qi and blood and strengthen the brain and soothe the nerves by stimulating the meridian acupoints on the head.

[0003] In the prior art, for middle-aged and elderly people and young people with high-intensity life and work, the increase in age or work pressure will greatly increase the occurrence of neurodegenerative diseases. At present, the relatively effective way to relieve them is health care physiotherapy of the neuromodulation type. However, at present, the physiotherapy equipment using transcranial magnetic stimulation devices is bulky, complex to operate, and not highly portable. Therefore, people generally need to go to the hospital or large physiotherapy places for experience, which is very inconvenient. If the comb is combined with the concept of health care, it can make physiotherapy intervention no longer limited to hospitals and professional institutions, enabling more people to benefit, providing a convenient health management method for specific populations, helping to relieve family and social pressure, and promoting the popularization of a healthy life.

[0004] Therefore, it is necessary to provide an intelligent comb product with health care physiotherapy effects. Summary of the Invention

[0005] Based on the above requirements, the present application provides an intelligent comb, which can perform health physiotherapy intervention through non-invasive multi-modal nerve stimulation based on brain wave signals.

The network communication module supports remote algorithm iteration and data sharing, enabling the stimulation strategy to be continuously optimized based on the cloud training model and user group data, improving the intervention accuracy. The system upgrades traditional physical care to an intelligent neuromodulation tool with adaptive capabilities through a closed-loop mechanism of bio-signal feedback and dynamic adjustment of stimulation parameters, and at the same time integrates complex monitoring and intervention processes into the daily hair combing action with a non-invasive design, taking into account both the convenience of use and the depth of health management, and expanding the cross-border integration potential of wearable devices in the fields of scalp care, stress relief and brain-computer interface applications.

[0037] To further elaborate on the technical means and effects adopted by the present invention to achieve the intended invention purpose, the following detailed description is given in conjunction with the accompanying drawings and preferred embodiments.

[0038] The positions of the shape, structure, modules, etc. of the intelligent comb shown in the embodiments of the present application are all schematic, and the present disclosure does not limit the positions of the shape, structure, modules, etc. of the intelligent comb.

[0039] As Figures 1-4 shown, the embodiment of the present application provides an intelligent comb, which includes a comb body 10 and comb teeth 20 arranged in an array on the comb body.

[0040] It further includes an electroencephalogram signal acquisition module 30, a data storage module 40, a multi-modal stimulus generation module 50, a control module 60, a power supply module 70, an impedance signal acquisition module 80, a user interaction module 90, a model algorithm module 100, and a networking communication module 200.

[0041] Among them, the brain wave signal acquisition module 30 is arranged at the end of the comb teeth 20 or in the gap of the comb teeth 20, and is used to acquire brain wave signals and send them to the control module 60; specifically, the inside of the comb body 10 is designed as a hollow structure for placing the control module 60, and the comb teeth 20 are also designed as hollow structures with cables for signal transmission placed inside. The cables are connected to the control module 60 and the brain wave signal acquisition module 30. The brain wave signal acquisition module 30 can be used for EEG brain wave acquisition, which includes acquisition electrodes and an amplifier. The electrical signals acquired by the acquisition electrodes are digitized and sent to the amplifier, and the amplified data can be displayed as a sequence of voltage values and transmitted to the control module 60.

[0042] The data storage module 40 is connected to the control module 60 and is used to store brain wave data and the corresponding stimulation schemes for the brain wave data. In an optional embodiment, the brain wave signal acquisition module 30 detects brain wave bioelectrical signals, and the brain wave data in the data storage module 40 is a dataset of brain wave bioelectrical signals of a person in various states, including but not limited to the brain wave characteristic values in various mental states such as sleep, wakefulness, excitement, exhaustion, tension, loss, happiness, sadness, etc. For example, it stores various characteristic values of Delta wave, Theta wave, Alpha wave, Beta wave, and Gamma wave, and there are multiple stimulation schemes preset for the characteristic parameters corresponding to each characteristic value, such as unimodal stimulation or multimodal mixed stimulation.

[0043] The control module 60 is connected to the multimodal stimulation generation module 50 and the data storage module 40, and is used to determine an initial stimulation scheme based on the brain wave signal and the brain wave database, and control the multimodal stimulation generation module 60 to generate corresponding stimulation behaviors according to the initial stimulation scheme.

[0044] The model algorithm module 100 is connected to the network communication module 200 and the data storage module 40, and is used to store the model algorithm and update the stimulation scheme corresponding to the brain wave data based on the data transmitted through the network communication module 200. The network communication module 200 is used to transmit data through the network and upgrade the model algorithm of the model algorithm module 100; specifically, it transmits data through communication protocols such as wifi, Bluetooth, or XingShan, and upgrades the model algorithm of the model algorithm module 100 through OTA (Over-the-Air Technology).

[0045] The intelligent comb further includes an impedance signal acquisition module 80 connected to the control module 60. The impedance signal acquisition module 80 is used to acquire skin or limb impedance signals, and the control module 60 adjusts the stimulation intensity, frequency, or mode of the stimulation behavior based on the impedance signals.

[0046] The control module 60 determines an initial stimulation plan based on the brain wave signals and the brain wave database, and controls the multi-modal stimulation generation module 50 to generate corresponding stimulation behaviors according to the initial stimulation plan.

[0047] The control module 60 is usually composed of a chip module and an integrated circuit. It matches the received voltage value sequence with the voltage value sequence in the data storage module 40. After determining the corresponding initial stimulation plan, it controls the multi-modal stimulation generation module 50 to generate corresponding stimulation behaviors according to the initial stimulation plan.

[0048] Among them, the power supply module 70 is used to supply power to the brain wave signal acquisition module 30, the data storage module 40, the multi-modal stimulation generation module 50, the control module 60, the power supply module 70, the impedance signal acquisition module 80, the user interaction module 90, the model algorithm module 100, and the networking communication module 200.

[0049] The light, sound, and vibration stimulations of this application are realized according to the neural oscillation effect. For example, Gamma oscillation (30 - 150 Hz) is the key rhythm of the brain's cognitive function. It plays an important role in the neural network and can enhance the effectiveness, accuracy, and selectivity of information communication between brain regions. It is related to the following mechanisms:

[0050] a) Neuron synchronization: The Gamma frequency promotes the synchronization of the neuron network and enhances the information processing efficiency;

[0051] b) Synaptic plasticity: Regulates the sensitivity of neurotransmitter receptors and affects memory and learning abilities;

[0052] c) Vascular coupling: The Gamma oscillation optimizes the blood flow supply to brain regions through the neurovascular coupling mechanism.

[0053] When external stimuli (such as light, sound, vibration) act on the sensory system at a specific frequency (such as 40 Hz), the brain neurons may synchronize with the stimulation frequency through the resonance mechanism, which is called the "entrainment effect". For example, sound stimuli can be transmitted to the cerebral cortex through the auditory nerve, mechanical vibrations can be transmitted to the cerebral cortex through the skull, and light stimuli can penetrate the skull (such as near-infrared light) and activate the visual cortex or affect the brain region activities through non-visual photoreceptors. This is called neural oscillation synchronization.

[0054] The odor stimulation of this application exerts a stimulating effect by connecting to the brain limbic system through the olfactory pathway. Specifically, odor molecules are converted into neural signals through the olfactory epithelial cell receptors in the nasal cavity and are transmitted to the olfactory bulb through the olfactory nerve. Subsequently, they bypass the thalamus and directly reach the amygdala (emotional center) and the hippocampus (memory center). This "fast track" enables odors to quickly trigger emotional responses and memory retrieval, forming the "Proust effect".

[0055] Functional magnetic resonance imaging (fMRI) shows that linalool in lavender enhances alpha brain waves (8-13 Hz) by regulating the level of gamma-aminobutyric acid (GABA), putting the brain into a relaxed and focused state. These regions are also involved in attention regulation, which can improve memory efficiency.

[0056] Research data from Tel Aviv University in Israel show that the efficiency of information integration between the hippocampus and the cerebral cortex of the subjects receiving odor stimulation is improved. Long-term exposure to specific scents (such as mint and rosemary) can increase the attention duration by about 20%, which may have a delaying effect on cognitive decline in the elderly.

[0057] Research data from the Baltimore Longitudinal Study of Aging at the University of California, Baltimore and the neuroscience research at the University of California, Irvine show that olfactory enhancement can significantly improve the memory of the elderly (after 6 months, the memory test score increases by 226%) and enhance the integrity of the left uncinate fasciculus in the brain.

[0058] Research data from phytomedicine research in Austria and Germany show that aromatherapy scents regulate emotions by activating the amygdala. For example, rose and jasmine essential oils can reduce the cortisol level (stress hormone) by 15%-25%, relieve emotional stress, and improve depressive symptoms. Research data from Kagoshima University and Kyorin University in Japan show that lavender relieves pre-sleep stress by enhancing alpha wave activity in the brain and simultaneously improves sleep quality. Their research data show that the sleep onset time of the subjects is shortened by 35% and the deep sleep stage is extended by 25%.

[0059] Therefore, in the embodiment of the present application, the multi-modal stimulation generation module 50 includes, in addition to the light stimulation unit 51 for generating light stimulation, the sound wave stimulation unit 52 for generating sound wave stimulation, and the vibration stimulation unit 53 for generating vibration, an odor stimulation unit 54 for generating a predetermined odor.

[0060] The light stimulation unit 51 includes an LED array or an optical fiber conduction array with adjustable wavelength or frequency within a predetermined range, and the optical fiber conduction array is arranged at the intervals of the comb teeth.

[0061] For example, a light source is formed by an LED array with an adjustable wavelength range of 460-1100 nm, and the light is transmitted to the cerebral cortex using an optical fiber conduction array. Among them, the frequency of the light stimulation is adjustable within 0.5-100 Hz, and the duty cycle of 10%-90% is programmable, so as to achieve a more flexible and multi-faceted light stimulation scheme.

[0062] The sound wave stimulation unit 52 includes one or more of bone conduction speakers and air conduction speakers.

[0063] In this embodiment, the sound wave stimulation unit 52 is formed by combining a bone conduction speaker and an air conduction speaker to form a composite sound wave stimulation, which is pre-modulated so that the fundamental frequency and the target brain wave frequency maintain a proportional harmonic relationship.

[0064] The vibration stimulation unit 53 includes a composite vibration system composed of an embedded micro motor, a piezoelectric ceramic vibration piece, or multiple mechanical vibration mechanisms.

[0065] Among them, in this application, a mechanical resonance frequency of 0.5 - 50 Hz is set, and the amplitude of vibration is adjusted in levels according to a preset setting.

[0066] The odor stimulation unit 54 includes a multi - cavity fragrance storage structure and a temperature - controlled volatilization module. The temperature - controlled volatilization module is used to control the fragrance in the multi - cavity fragrance storage structure to release odor at a predetermined volatilization rate.

[0067] In an alternative embodiment, the multi - cavity fragrance storage structure is a closed - type aromatherapy box 541. The temperature - controlled volatilization module includes a heating element and an electric control valve for controlling the opening and closing degree of the aromatherapy box, and can achieve the release of odor molecules with an accuracy of up to 0.1 ml / min.

[0068] In order to adjust according to the usage situation of the user, this application also introduces a closed - loop feedback regulation mechanism. Specifically, the brain wave signal acquisition module 30 acquires the brain wave signal during use. The built - in model algorithm intelligently analyzes the brain wave database and the stimulation plan in the data storage module based on the brain wave signal and the impedance signal during use, and triggers the control module to adjust the stimulation intensity, frequency, or mode of the stimulation behavior.

[0069] Preferably, the closed - loop feedback regulation mechanism performs algorithm iteration based on a neural network model, so as to improve the stimulation plan according to the user's demand habits and enhance the intervention and health care effects.

[0070] Specifically, it further includes a comb handle 11. The comb body 10 is detachably connected to one end of the comb handle 11. The comb body 10 is provided with bristles 101 formed by an optical fiber bundle. The optical fiber bundle is used to collect and transmit near - infrared light for the acquisition of skin impedance signals. During actual use, more real and effective skin impedance data is formed according to the simultaneous acquisition of multiple optical fiber bundles and weighted processing according to regions, strengthening the efficiency and quality of the closed - loop feedback regulation.

[0071] The following are two example combined stimulation plans. Those skilled in the art can adaptively modify the preset stimulation plan of this intelligent comb according to requirements, so as to form more diversified health care and physical therapy plans.

[0072] The first stimulation plan: Alzheimer's disease intervention mode

[0073] Activating γ - wave stimulation: Set a 40 Hz light pulse (duty cycle 30%), cooperate with an 80 Hz harmonic audio frequency, the mechanical vibration adopts a 40 Hz main frequency superimposed with a 5 Hz modulation wave, and the aromatherapy box releases a compound preparation of huperzine A microcapsules and rosemary essential oil.

[0074] Second Stimulation Program: Bedtime Stress Relief and Sleep Aid Mode

[0075] Activate the theta wave dominant program: 7Hz photoacoustic synchronous stimulation, the vibration module generates a 0.5 - 3Hz imitation cradle fluctuation, the aromatherapy box releases a mixed volatile agent of lavender and valerian extracts, and adjusts the stimulation intensity according to the heart rate variability (HRV).

[0076] To enable users to have a more personalized experience when using this intelligent comb, it also includes a user interaction module 90 connected to the control module 50. The user interaction module 90 is used to feedback the parameters of the stimulation program and stimulation behavior. The user interaction module 90 includes a touch screen, a voice control module, or a multi-modal interaction system composed of multiple interaction modules. Users can edit and input or select the stimulation program or adjust the corresponding parameters of the stimulation behavior through the user interaction module, such as selecting the stimulation program or adjusting the parameters of the stimulation behavior by touching the touch screen or voice input.

[0077] It can be understood that the initial stimulation program is default determined by the control module 60 and the data storage module 40 based on the brain wave signal and the brain wave database. However, when users have personalized needs and perform manual settings or adjustments on the initial stimulation program, the priority of this setting or adjustment is higher than that of the initial stimulation program default by the system.

[0078] More preferably, the user interaction module 90 is connected to the network communication module 200, and users can directly customize and control the work of each stimulation module through software apps or mini-programs on mobile terminals (such as mobile phones, tablets).

[0079] As an optional embodiment, the comb body 10 is detachably connected to one end of the comb handle 11 by plugging. The inside of the comb handle 11 serves as a housing for the power module 70. The end of the comb handle 11 and the comb body 10 are designed in a power plugging manner. The power module 70 can be removed separately for charging. The comb body 10 can be used as an ordinary comb without being powered on, which enriches the usage scenarios and functions of the comb.

[0080] As Figure 2 shown, the aromatherapy box 541 can be set on the comb body 10. However, in some embodiments, due to the large number of modules set on the comb body 10, it can also be as Figure 3 shown, and the aromatherapy box 541 is set on the comb handle 11.

[0081] To make the comb body 10 have a comfortable feeling when contacting the human body, the surface of the comb body 10 is provided with a biocompatible material substrate, such as silicone.

[0082] When in use, with the power module 70 turned on, the user touches the end of the comb teeth 20 to the scalp and stays still for about 1 - 2s, asFigure 5 As shown, the brain wave signal acquisition module 30 acquires brain wave signals and sends them to the control module 60. The control module 60 determines an initial stimulation plan based on the brain wave signals and the brain wave database. During the process of the stimulation behavior generated by the multimodal stimulation generation module 50 according to the initial stimulation plan, the impedance signal acquisition module 80 acquires skin impedance signals, and the control module 60 adjusts the stimulation intensity of the stimulation behavior based on the skin impedance signals, thereby performing intelligent closed-loop feedback type head stimulation. It is also possible to directly use the touch screen of the user interaction module 90 or the voice control module to implement the selection of the initial stimulation plan or the adjustment of parameters during the stimulation behavior.

[0083] Generally speaking, through modular integration of dual-modal biosensing of brain waves and skin impedance signals, combined with multimodal physical stimulation and cloud collaborative algorithms, this intelligent comb constructs a dynamic closed-loop neuro-physiological collaborative intervention system. The core of its technology lies in using the brain wave acquisition module and impedance detection module distributed in the comb teeth gaps or at the ends to synchronously obtain scalp neural electrical activities and skin impedance changes, forming a multi-dimensional physiological state assessment system; through built-in model algorithms for cross-analysis of the brain wave database, stimulation plans and data, intelligently triggering combined modes of composite stimulations such as light, sound, smell, vibration, etc., to achieve intelligent intervention and regulation for health needs such as cognitive function protection, emotion and sleep improvement, prevention of neurodegenerative diseases, and optimization of daily functions. The networking communication module supports remote algorithm iteration and data sharing, enabling the stimulation strategy to be continuously optimized based on cloud training models and user group data, improving the accuracy of intervention. Through the closed-loop mechanism of biological signal feedback and dynamic adjustment of stimulation parameters, the system upgrades traditional physical care to an intelligent neuromodulation tool with adaptive capabilities. At the same time, with a non-invasive design, it integrates complex monitoring and intervention processes into daily hair combing actions, taking into account both the convenience of use and the depth of health management, expanding the potential for cross-border integration of wearable devices in fields such as scalp care, stress relief, and brain-computer interface applications.

[0084] The above are only preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the above-disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
