Description

Technical Field

[0001] This invention relates to the field of human body state regulation technology, specifically to a non-therapeutic method for respiratory and neural regulation based on bilateral nasal cavity control. Background Technology

[0002] With the increasing demand for respiratory health management, breathing training, as a non-invasive and self-administered health intervention, is becoming a promising development direction in daily health scenarios. Currently, the dominant technology in the industry is mouth breathing resistance training, which focuses on strengthening respiratory muscle function; nasal breathing-related implementation methods are only a niche branch, primarily aimed at correcting mouth breathing habits and helping to reduce snoring; while autonomic nervous system regulation based on breathing patterns, as a high-value emerging direction, has not yet formed a mature technical system and implementation methods.

[0003] Currently, the field of breathing training has formed two clearly defined and non-overlapping technical routes, each corresponding to specific application scenarios, focusing on different niche needs. However, both routes have inherent limitations that cannot be overcome, and neither has achieved effective autonomic nervous system regulation.

[0004] The first technical approach is mouth breathing resistance training (the industry mainstream). It creates concentrated airflow obstruction through a direct airway via the mouth, generating significantly higher local abdominal pressure than the nasal route. This effectively improves the respiratory muscles' maximum strength and basic endurance, and is currently the standard implementation method in respiratory muscle training, playing an irreplaceable role in specialized respiratory muscle strength training. However, this technique has three inherent limitations:

[0005] 1. It cannot rely on nasal ventilation to coordinate with the autonomic nervous system, only generating single sympathetic nerve excitation and lacking multimodal autonomic nervous regulation ability; it cannot coordinate with bilateral nasal airflow distribution and physiological nasal cycle operation, directly abandoning all targeted upper respiratory tract training functions.

[0006] 2. When wearing the device, the user cannot speak normally or carry out daily activities, limiting its applicability and making it difficult to use continuously for extended periods.

[0007] 3. Compared to nasal training, mouth training requires the lips to be tightly closed to lock in air, and the facial muscles are constantly tense. When exhaling, it is easy to actively contract the face to increase pressure. Under the same intensity, the muscle load is higher and fatigue is very easy. At the same time, it cannot optimize the original breathing pattern. Long-term use can easily lead to the solidification of incorrect breathing and the compensation of trunk muscle groups. It is only suitable for short-term specific training.

[0008] The second technical approach involves nasal breathing assistance and training, with the core function of correcting mouth breathing habits and helping to reduce snoring. It also has only a very limited basic respiratory muscle training effect and currently has three major limitations:

[0009] 1. Respiratory resistance is only passively controlled: Existing implementation methods employ only two types of passive resistance control logic, failing to achieve active and precise intervention. One type is a fixed-quantity resistance method, where resistance parameters are preset. Essentially, airflow accommodates resistance, and the user can only passively adapt to the fixed resistance with no room for adjustment. The other type is a passive adaptive method, where expiratory resistance remains constant, while only inspiratory resistance can passively change with breathing intensity. Essentially, resistance accommodates airflow, only slightly buffering resistance fluctuations during inhalation. Neither type can actively set resistance parameters based on preset training goals and neural regulation needs, nor can it achieve independent and differentiated ratios of inspiratory and expiratory resistance. Furthermore, the human body has a physiological nasal cycle, and the baseline resistance of both nasal cavities changes naturally and periodically. Existing methods cannot correct for these resistance fluctuations, ultimately leading to a continuous deviation in actual respiratory resistance, making training intensity and intervention effects uncontrollable.

[0010] 2. Insufficient bilateral nasal cavity control: Existing methods cannot achieve independent allocation and differentiated control of the effective ventilation area of ​​the left and right nasal cavities, cannot set the bilateral ventilation ratio according to usage needs, and have failed to utilize the physiological nasal cycle and the neural bias pattern dominated by unilateral ventilation to develop an implementation approach related to autonomic nervous system regulation.

[0011] 3. The wearing and ventilation methods have inherent physiological defects: The existing nasal intervention ventilation method goes deep into the nasal cavity and crosses the nasal threshold, directly compressing the anterior end of the inferior turbinate which participates in the physiological nasal cycle, disrupting the normal alternating congestion and relaxation rhythm of both turbinates. Long-term use can easily cause problems such as nasal mucosal edema, persistent nasal congestion, and nasal cycle disorder. At the same time, the foreign body sensation is obvious, the comfort is insufficient, and it is difficult to use stably for a long time.

[0012] In summary, the two existing technical approaches are each limited to their own specific scenarios and have failed to form a complete implementation system covering all scenarios. They cannot achieve refined layered training of the entire respiratory airway, nor can they explore the core value of the nasal cavity pathway in terms of autonomic nervous regulation.

[0013] Based on this, the present invention proposes a breathing and neural regulation method based on bilateral nasal cavity control, applicable to healthy individuals and for non-therapeutic purposes. It aims to break through the limitations of existing technologies, actively adapt to and regulate the nasal cycle, and achieve an organic combination of breathing training and neural regulation. Summary of the Invention

[0014] The purpose of this invention is to provide a non-therapeutic method for respiratory and neuromodulation based on bilateral nasal cavity control. This invention achieves multi-modal regulation of respiratory mode optimization and autonomic nervous system state by adjusting the airflow distribution relationship between the two nasal cavities and combining the ratio configuration of respiratory resistance parameters.

[0015] In order to achieve the above-mentioned objectives of the present invention, the following technical solution is adopted:

[0016] The first aspect of this invention provides a non-therapeutic method for respiratory and neural regulation based on bilateral nasal cavity control, the method comprising:

[0017] By adjusting the airflow distribution relationship between the two nasal cavities and combining it with the ratio configuration of respiratory resistance parameters, multi-modal regulation of breathing pattern optimization and autonomic nervous system state can be achieved.

[0018] Preferably, the bilateral nasal airflow distribution relationship is divided into three working states:

[0019] When the effective ventilation area of ​​the left nasal cavity is greater than that of the right nasal cavity, left-side ventilation becomes dominant, corresponding to different autonomic nervous system regulatory states.

[0020] When the effective ventilation area of ​​the right nasal cavity is greater than that of the left nasal cavity, right-side ventilation becomes dominant, corresponding to different autonomic nervous system regulatory states.

[0021] When the effective ventilation area of ​​the left nasal cavity is equal to that of the right nasal cavity, the ventilation of the left and right nasal cavities is balanced, maintaining the body's autonomic nervous system in a balanced state.

[0022] Preferably, by adjusting the ratio of the effective ventilation area of ​​the left and right nasal cavities, different neurofunctional effects can be achieved in a gradient manner:

[0023] When the ratio of the effective ventilation area of ​​the left and right nasal cavities reaches the maximum effect point, the nerve function effect formed by the original unilateral nasal ventilation reaches its maximum value.

[0024] When the ratio of the effective ventilation area of ​​the left and right nasal cavities exceeds the maximum effect point but does not reach the effect decay threshold, the original nerve function effect gradually decays with the change of the ratio.

[0025] When the ratio of the effective ventilation area of ​​the left and right nasal cavities exceeds the effect attenuation threshold, the original nerve function effect is suppressed and approaches ineffectiveness.

[0026] Preferably, the configuration of the respiratory resistance parameters reflects the ratio of inspiratory resistance to expiratory resistance. Different ratios regulate the autonomic nervous system through the dual effects of respiratory load and respiratory duration. Simultaneously, by utilizing different resistance ratios to create a gradient respiratory load, targeted training of the respiratory muscles is achieved.

[0027] When the expiratory resistance is greater than the inspiratory resistance, the respiratory load increases during the expiratory phase. The parasympathetic nerve afferent signals are strengthened by the proprioceptors of the respiratory muscles. At the same time, the expiratory resistance passively prolongs the expiratory duration, continuously lengthening the activation duration of the parasympathetic nerves, enhancing the body's tendency to relax and promote sleep, and simultaneously strengthening the strength and endurance of the expiratory muscle groups.

[0028] When the inspiratory resistance is greater than the expiratory resistance, the respiratory load increases during the inspiratory phase. At the same time, the inspiratory resistance passively prolongs the inspiratory duration, continuously lengthening the activation duration of the sympathetic nervous system, enhancing the body's regulatory effect towards wakefulness and alertness, and simultaneously strengthening the muscle strength and endurance of the inspiratory muscle groups.

[0029] When the inspiratory resistance is equal to the expiratory resistance, the respiratory load is balanced during the inspiratory and expiratory phases, the respiratory phases remain symmetrical, and the intensity and duration of alternating activation of the sympathetic and parasympathetic nervous systems tend to be consistent, maintaining the balance of the body's autonomic nervous system and simultaneously achieving balanced training of the inspiratory and expiratory muscles.

[0030] Preferably, a gradient respiratory load is formed by adjusting the overall nasal cavity occlusion ratio; the ventilation area is divided into a fixed ventilation section and an adjustable section. The fixed ventilation section is always kept ventilated, and the ratio adjustment is carried out within the range of the adjustable section; the adjustable section has an inherent physiological boundary benchmark. When the adjustment ratio is lower than the boundary benchmark, breathing is mainly driven by the diaphragm. When the adjustment ratio is higher than the boundary benchmark, breathing is mainly driven by the abdominal muscles and accessory respiratory muscles.

[0031] Preferably, the duration ratio of the respiratory phases is mainly determined by the ratio of inspiratory and expiratory resistance and the overall respiratory load; using the duration ratio of the respiratory phases as a control variable, a gradient neural regulation effect is achieved:

[0032] When the respiratory phase duration ratio has not reached the maximum effect point, the neural regulation effect gradually increases;

[0033] When the respiratory phase duration ratio reaches the maximum effect point but has not reached the effect decay threshold, the original neural bias effect gradually decays.

[0034] When the respiratory phase duration ratio exceeds the effect decay threshold, the original neural regulatory effect is suppressed and approaches ineffectiveness.

[0035] Preferably, the working mode centered on respiratory muscle training relies on the load formed by respiratory resistance to achieve the training effect. It can adopt a balanced working condition in which the effective ventilation area of ​​the left and right nasal cavities is equal and the inspiratory resistance and expiratory resistance are equal. At the same time, it can be used in conjunction with a working condition with neural bias, and the neural bias will not affect the training effect of the respiratory muscle group.

[0036] Preferably, the working mode centered on neural state regulation establishes a basic neural bias based on the ratio of the effective ventilation area of ​​the left and right nasal cavities, corresponding to the regulatory effects of wakefulness, relaxation, sleep, and post-exercise recovery. By adopting a differentiated resistance ratio for inhalation and exhalation, changes in resistance parameters can alter both the proprioceptive input level of the respiratory muscle groups and the respiratory duration ratio. The aforementioned basic neural bias is amplified and regulated by the synergistic effect of changes in proprioceptive input and respiratory duration ratio.

[0037] Preferably, the method objectively forms two working modes through parameter adjustment:

[0038] The core working mode is respiratory muscle training, and the corresponding functions include respiratory muscle training, exercise-assisted enhancement, sleep breathing rhythm stabilization, oral and maxillofacial muscle care, and oral cavity and airway self-cleaning.

[0039] The working mode is based on the regulation of the nervous state, and the corresponding functions include wakefulness and alertness, relaxation, nerve-induced sleep aid, and post-exercise recovery.

[0040] Preferably, the bilateral nasal cavity controlled breathing regulation device for implementing the method includes a control unit; the control unit is worn in the nasal vestibule and does not exceed the nasal threshold, and has the dual functions of independently adjusting the ventilation area of ​​the left and right nasal cavities and independently adjusting the ratio of inhalation and expiration resistance; during operation, the ventilation range is limited to the nasal vestibule and does not exceed the nasal threshold, avoiding interference with the human physiological nasal cycle and improving the safety and comfort of use.

[0041] Compared with the prior art, the beneficial effects of the present invention include at least the following:

[0042] This invention optimizes breathing patterns and strengthens respiratory muscle function by adjusting the airflow distribution between the two nasal cavities and configuring the respiratory resistance parameters. Simultaneously, it achieves multi-modal regulation of the autonomic nervous system, enabling precise control of different neural states such as wakefulness, relaxation, sleep, and post-exercise recovery without the need for drugs or complex equipment. This method is safe, non-invasive, and easy to implement, and can be applied to non-therapeutic scenarios such as daily status management, respiratory function improvement, fatigue relief, or sleep improvement. Detailed Implementation

[0043] The embodiments of the technical solution of the present invention will be described in detail below with reference to the examples. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, and are therefore only examples, and should not be used to limit the scope of protection of the present invention.

[0044] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0045] This invention provides a non-therapeutic method for respiratory and neural regulation based on bilateral nasal cavity control, the method comprising:

[0046] By adjusting the airflow distribution relationship between the two nasal cavities and combining it with the ratio configuration of respiratory resistance parameters, multi-modal regulation of breathing pattern optimization and autonomic nervous system state can be achieved.

[0047] The parameter thresholds set in each embodiment of this invention are all calibrated based on publicly available academic literature and clinical studies related to respiratory physiology, nasal nerve reflexes, and respiratory muscle load characteristics. The respiratory muscle activation threshold is an inherent physiological parameter of the human body. Due to individual differences in the physical condition and respiratory tolerance of different users, conditions where parameters exceed the normal usage range can only be used for limited periods. Users need to independently control the usage time based on their own circumstances. This invention is not suitable for individuals with severe nasal diseases, respiratory diseases, or other conditions unsuitable for airway resistance adjustment.

[0048] The control unit described in this application is a component adapted for wearing in the nasal vestibule. It enables the adjustment of the ventilation area of ​​both nasal cavities in stages and the independent ratio of inspiratory and expiratory resistance. This can be achieved by combining a conventional bilateral throttling structure and an independent breathing resistance component in nasal breathing devices of the art. All parameters of this invention are calibrated based on a total cross-sectional area of ​​50 mm² for one nasal cavity in an adult, and a total cross-sectional area of ​​100 mm² for both nasal cavities. In actual use, it can be linearly adjusted proportionally according to the user's nasal cavity size.

[0049] Parameter logic description:

[0050] This invention comprises three core adjustment parameters: the nasal cavity occlusion ratio controls overall ventilation resistance, the ratio of effective ventilation area between the left and right nasal cavities distributes airflow bilaterally, and these parameters are used in conjunction with different inspiratory and expiratory resistance modes. These three parameters collectively govern the respiratory phase.

[0051] 1. Nasal cavity occlusion ratio:

[0052] 35% is the reference threshold for normal use: when the occlusion ratio is below 35%, the human respiratory compensation mechanism can completely offset the additional breathing resistance, and it can be used for a long time in a normal manner; when the occlusion ratio is above 35%, the work done by the respiratory muscles increases non-linearly, and it can only be used for a limited time.

[0053] 70% is the intrinsic respiratory muscle threshold. Below this value, breathing is mainly controlled by the diaphragm, while above this value, breathing is mainly controlled by the abdominal muscles and accessory respiratory muscles.

[0054] The nasal cavity cross-section is divided into an adjustable working zone and a fixed ventilation zone. The fixed ventilation zone is a permanently retained ventilation structure that cannot be adjusted for occlusion; the occlusion ratio is set within the adjustable working zone, with an adjustment range limited to 0%–80%.

[0055] 2. The ratio of the effective ventilation area of ​​the left and right nasal cavities:

[0056] A ratio of 2:8 represents the maximum effect point, and 0.5:9.5 represents the effect decay threshold. When the ratio reaches the maximum effect point, the neural regulation effect is optimal; when the ratio is between the maximum effect point and the effect decay threshold, the regulation effect gradually decays; when the ratio exceeds the effect decay threshold, the targeted regulation effect weakens significantly and approaches ineffectiveness.

[0057] At the same occlusion ratio, the higher the occlusion ratio, the higher the corresponding baseline breathing resistance.

[0058] 3. Respiratory phases and resistance patterns:

[0059] There are three types of resistance modes: inspiratory resistance equals expiratory resistance, inspiratory resistance is greater than expiratory resistance, and expiratory resistance is greater than inspiratory resistance.

[0060] Different resistance modes, in combination with the aforementioned parameters, form corresponding respiratory phases. The neural regulation effect is optimal when the ratio of inhalation to exhalation duration is 1:3; the regulatory effect gradually weakens within the range of 1:3 to 1:5; and the regulatory effect essentially disappears beyond the 1:5 range.

[0061] In one embodiment, the bilateral nasal airflow distribution relationship is divided into three working states:

[0062] When the effective ventilation area of ​​the left nasal cavity is greater than that of the right nasal cavity, left-side ventilation becomes dominant, corresponding to different autonomic nervous system regulatory states.

[0063] When the effective ventilation area of ​​the right nasal cavity is greater than that of the left nasal cavity, right-side ventilation becomes dominant, corresponding to different autonomic nervous system regulatory states.

[0064] When the effective ventilation area of ​​the left nasal cavity is equal to that of the right nasal cavity, the ventilation of the left and right nasal cavities is balanced, maintaining the body's autonomic nervous system in a balanced state.

[0065] In one embodiment, by adjusting the ratio of the effective ventilation areas of the left and right nasal cavities, different neurofunctional effects are achieved in a gradient manner:

[0066] When the ratio of the effective ventilation area of ​​the left and right nasal cavities reaches the maximum effect point, the nerve function effect formed by the original unilateral nasal ventilation reaches its maximum value.

[0067] When the ratio of the effective ventilation area of ​​the left and right nasal cavities exceeds the maximum effect point but does not reach the effect decay threshold, the original nerve function effect gradually decays with the change of the ratio.

[0068] When the ratio of the effective ventilation area of ​​the left and right nasal cavities exceeds the effect attenuation threshold, the original nerve function effect is suppressed and approaches ineffectiveness.

[0069] In one embodiment, the configuration of the respiratory resistance parameters reflects the ratio of inspiratory resistance to expiratory resistance. Different ratios regulate the autonomic nervous system through the dual effects of respiratory load and respiratory duration. Simultaneously, by using different resistance ratios to form a gradient respiratory load, targeted training of the respiratory muscles is achieved.

[0070] When the expiratory resistance is greater than the inspiratory resistance, the respiratory load increases during the expiratory phase. The parasympathetic nerve afferent signals are strengthened by the proprioceptors of the respiratory muscles. At the same time, the expiratory resistance passively prolongs the expiratory duration, continuously lengthening the activation duration of the parasympathetic nerves, enhancing the body's tendency to relax and promote sleep, and simultaneously strengthening the strength and endurance of the expiratory muscle groups.

[0071] When the inspiratory resistance is greater than the expiratory resistance, the respiratory load increases during the inspiratory phase. At the same time, the inspiratory resistance passively prolongs the inspiratory duration, continuously lengthening the activation duration of the sympathetic nervous system, enhancing the body's regulatory effect towards wakefulness and alertness, and simultaneously strengthening the muscle strength and endurance of the inspiratory muscle groups.

[0072] When the inspiratory resistance is equal to the expiratory resistance, the respiratory load is balanced during the inspiratory and expiratory phases, the respiratory phases remain symmetrical, and the intensity and duration of alternating activation of the sympathetic and parasympathetic nervous systems tend to be consistent, maintaining the balance of the body's autonomic nervous system and simultaneously achieving balanced training of the inspiratory and expiratory muscles.

[0073] In one embodiment, a gradient respiratory load is formed by adjusting the overall nasal cavity occlusion ratio; the ventilation area is divided into a fixed ventilation section and an adjustable section. The fixed ventilation section is always kept ventilated, and the ratio adjustment is carried out within the range of the adjustable section; the adjustable section has an inherent physiological boundary benchmark. When the adjustment ratio is lower than the boundary benchmark, breathing is mainly driven by the diaphragm, and when the adjustment ratio is higher than the boundary benchmark, breathing is mainly driven by the abdominal muscles and accessory respiratory muscles.

[0074] In one embodiment, the duration ratio of the respiratory phases is mainly determined by the ratio of inspiratory and expiratory resistance and the overall respiratory load; using the duration ratio of the respiratory phases as a control variable, a gradient neural regulation effect is achieved:

[0075] When the respiratory phase duration ratio has not reached the maximum effect point, the neural regulation effect gradually increases;

[0076] When the respiratory phase duration ratio reaches the maximum effect point but has not reached the effect decay threshold, the original neural bias effect gradually decays.

[0077] When the respiratory phase duration ratio exceeds the effect decay threshold, the original neural regulatory effect is suppressed and approaches ineffectiveness.

[0078] In one embodiment, the working mode centered on respiratory muscle training relies on the load formed by respiratory resistance to achieve the training effect. It can adopt a balanced working condition in which the effective ventilation area of ​​the left and right nasal cavities is equal and the inspiratory resistance and expiratory resistance are equal. At the same time, it can be used in conjunction with a working condition with neural bias, and the neural bias will not affect the training effect of the respiratory muscle group.

[0079] In one embodiment, the working mode centered on neural state regulation establishes a basic neural bias based on the ratio of the effective ventilation area of ​​the left and right nasal cavities, corresponding to the regulatory effects of wakefulness, relaxation, sleep, and post-exercise recovery. By adopting a differentiated resistance ratio for inhalation and exhalation, changes in resistance parameters can alter both the proprioceptive input level of the respiratory muscle groups and the respiratory duration ratio. The aforementioned basic neural bias is amplified and regulated by the synergistic effect of changes in proprioceptive input and respiratory duration ratio.

[0080] In one embodiment, the method objectively forms two working modes through parameter adjustment:

[0081] The core working mode is respiratory muscle training, and the corresponding functions include respiratory muscle training, exercise-assisted enhancement, sleep breathing rhythm stabilization, oral and maxillofacial muscle care, and oral cavity and airway self-cleaning.

[0082] The working mode is based on the regulation of the nervous state, and the corresponding functions include wakefulness and alertness, relaxation, nerve-induced sleep aid, and post-exercise recovery.

[0083] In one embodiment, it is preferable to limit the ventilation range to the user's nasal vestibule and not exceed the nasal threshold during use, so as to avoid interfering with the human physiological nasal cycle and improve the safety and comfort of use.

[0084] The technical solution of the present invention will be further described in detail below through specific embodiments.

[0085] Example 1

[0086] This embodiment is a non-therapeutic method for respiratory and neuromodulation based on bilateral nasal cavity control (diaphragm training), the method including:

[0087] Bilateral nasal cavities were simultaneously blocked, with a blocking ratio of 50%. The ratio of the effective ventilation area of ​​the left and right nasal cavities was 3:7, and the resistance mode was such that the inspiratory resistance was equal to the expiratory resistance.

[0088] Technical Description: A 50% occlusion rate, exceeding the 35% reference threshold for normal use, necessitates time-limited use. When this rate is below the 70% respiratory muscle threshold, respiratory work during quiet breathing is primarily mediated by the diaphragm. The ratio of the effective ventilation area of ​​the left and right nasal cavities is within an effective controllable range; inspiratory resistance equals expiratory resistance, allowing the respiratory phase to approach a 1:1 ratio. The occlusion rate, the ratio of effective ventilation area per cavity, and the respiratory phase work synergistically for overall stability.

[0089] Usage requirements: Use only for short periods of time; do not run continuously for extended periods.

[0090] Example 2

[0091] This embodiment is a non-therapeutic method for respiratory and neural regulation based on bilateral nasal cavity control (sleep breathing rhythm stabilization), the method including:

[0092] Bilateral nasal cavity occlusion was performed simultaneously, with an occlusion ratio of 35%. The ratio of the effective ventilation area of ​​the left and right nasal cavities was 1:1, and the resistance mode was such that the expiratory resistance was greater than the inspiratory resistance.

[0093] Technical Description: The occlusion ratio reaches the reference threshold for normal use and can be used for extended periods. The effective ventilation area of ​​each bilateral single-chamber ventilation is balanced, and the various parameters work synergistically to smoothly regulate the respiratory rhythm, making it suitable for sleep scenarios.

[0094] Usage requirements: Can be used as needed in different time periods.

[0095] Example 3

[0096] This embodiment is a non-therapeutic method for respiratory and neural regulation based on bilateral nasal cavity control (morning wakefulness regulation), the method including:

[0097] Bilateral nasal cavity occlusion was performed simultaneously, with an occlusion ratio of 50%. The ratio of the effective ventilation area of ​​the left and right nasal cavities was 3:7, and the resistance mode was that the inspiratory resistance was greater than the expiratory resistance by 2:1.

[0098] Technical Notes: A 50% occlusion rate, exceeding the 35% reference threshold for normal use, necessitates time-limited use. The effective ventilation area of ​​the left and right nasal cavities is predominantly on the right side, effectively achieving neural arousal. The respiratory phase corresponding to inspiratory resistance exceeding expiratory resistance is determined by the resistance base. Under this parameter combination, the 3:1 ratio of inspiratory to expiratory time does not reach the optimal state; however, a good neural arousal effect can still be achieved by utilizing the three-dimensional parameters.

[0099] Usage requirements: Each use should not exceed 10 minutes and should not be used continuously for extended periods.

[0100] Example 4

[0101] This embodiment describes a non-therapeutic method for respiratory and neural regulation based on bilateral nasal cavity control (nighttime neural induction sleep aid), the method comprising:

[0102] Only the right nasal cavity was blocked, with a right nasal cavity blockage rate of 28%. The left nasal cavity was not blocked, and the resistance mode was that the expiratory resistance was greater than the inspiratory resistance.

[0103] Technical Description: The left nasal cavity remains fully open, while the right nasal cavity is 28% blocked, a level within the normal usage range. Based on the body's natural nasal cycle physiological rhythms, when nasal cycle ventilation tends to induce wakefulness, this unilateral blocking method can intervene to counteract this trend, restoring bilateral ventilation and nerve tension to a balanced state, smoothly inducing sleep. Most users experience no noticeable physical sensation during use.

[0104] Usage requirements: Can be used as needed in different time periods.

[0105] Example 5

[0106] This embodiment is a non-therapeutic method for respiratory and neuromodulation based on bilateral nasal cavity control (maintenance of maxillofacial muscles and self-cleaning of the oral cavity and airway), the method including:

[0107] Bilateral nasal cavity occlusion was performed simultaneously, with an occlusion ratio of 75%. The ratio of the effective ventilation area of ​​the left and right nasal cavities was 2:1, and the resistance mode was such that the expiratory resistance was greater than the inspiratory resistance.

[0108] Technical Description: This system achieves 75% overall occlusion, exceeding the 35% threshold for conventional use. This value breaches the respiratory muscle's critical value, leading to compensatory work by the abdominal muscles during resting breathing, thus requiring time-limited use. Combined with a 2:1 ventilation ratio between the left and right nasal cavities and a setting where expiratory resistance is greater than inspiratory resistance, it prolongs expiratory time to induce parasympathetic nerve excitation and promote relaxation. Expiratory positive airway pressure drives passive activity of the maxillofacial muscles. Saliva secretion is promoted through a dual pathway of muscle mechanical compression and parasympathetic nerve regulation. Saliva flows through the oral cavity and upper airway with physiological swallowing, leveraging its inherent physiological functions to achieve maxillofacial muscle maintenance and internal oral and airway cleansing.

[0109] Usage requirements: Use only for short periods of time; do not run continuously for extended periods.

[0110] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them.

When the respiratory phase duration ratio exceeds the effect decay threshold, the original neural regulatory effect is suppressed and approaches ineffectiveness.

7. The method according to claim 4, characterized in that, The working mode, which focuses on training respiratory muscle groups, achieves its training effect by relying on the load formed by respiratory resistance. It can adopt a balanced working condition in which the effective ventilation area of ​​the left and right nasal cavities is equal and the inspiratory resistance and expiratory resistance are equal. It can also be used in situations with neural bias, and the neural bias will not affect the training effect of the respiratory muscle group.

8. The method according to claim 4, characterized in that, The working mode, which is based on the regulation of the neural state, establishes a basic neural bias based on the ratio of the effective ventilation area of ​​the left and right nasal cavities, and achieves the regulatory effects of wakefulness, relaxation, sleep, and post-exercise recovery. It adopts a differentiated resistance ratio for inhalation and exhalation. When the resistance parameter changes, it can change both the proprioceptive input level of the respiratory muscle group and the respiratory duration ratio. By relying on the synergistic effect of the changes in proprioceptive input and respiratory duration ratio, the aforementioned basic neural bias is regulated and amplified.

9. The method according to claim 1, characterized in that, The method objectively forms two working modes through parameter adjustment: The core working mode is respiratory muscle training, and the corresponding functions include respiratory muscle training, exercise-assisted enhancement, sleep respiratory rhythm stabilization, oral and maxillofacial muscle care, and oral cavity and airway self-cleaning. The working mode is based on the regulation of the nervous state, and the corresponding functions include wakefulness and alertness, relaxation, nerve-induced sleep aid, and post-exercise recovery.

10. A bilateral nasal cavity controlled breathing regulation device for implementing the method of any one of claims 1 to 9, characterized in that: It includes a control unit; the control unit is worn in the nasal vestibule and does not exceed the nasal threshold, and has the dual functions of independently adjusting the ventilation area of ​​the left and right nasal cavities and independently adjusting the ratio of inhalation and exhalation resistance.
