Description

Technical Field

[0001] This application belongs to the field of wearable devices, and particularly relates to a control method for a bidirectional turbofan nose-wearing device and a bidirectional turbofan nose-wearing device. Background Technology

[0002] With the improvement of people's living standards, the demand for respiratory health and related wearable devices is increasing. In daily life and work, people face air quality problems and the inconvenience of using respiratory assistive devices. Currently, the relevant technologies for respiratory health and related wearable devices mainly fall into three categories: first, traditional passive filtration nose-worn products (such as PM2.5 masks), which rely on physical barriers to achieve basic filtration; second, electrically powered respiratory assistive devices (such as CPAP machines), which assist breathing through mechanical power; and third, smart wearable nose-worn devices (such as the Apple nose ring), which focus on monitoring respiratory status. These technologies have been applied in the fields of filtration, assistance, or monitoring, but have not yet achieved comprehensive synergy of functions.

[0041] With the improvement of people's living standards, the demand for respiratory health and related wearable devices is increasing. In daily life and work, people face air quality problems and the inconvenience of using respiratory assistive devices. Currently, the relevant technologies for respiratory health and related wearable devices mainly fall into three categories: first, traditional passive filtration nose-worn products (such as PM2.5 masks), which rely on physical barriers to achieve basic filtration; second, electrically powered respiratory assistive devices (such as CPAP machines), which assist breathing through mechanical power; and third, smart wearable nose-worn devices (such as the Apple nose ring), which focus on monitoring respiratory status. These technologies have been applied in the fields of filtration, assistance, or monitoring, but have not yet achieved comprehensive synergy of functions.

[0042] Traditional nasal wearable devices suffer from increased breathing resistance due to their passive filtration design and lack of active oxygen supply, making them ineffective in high-intensity breathing scenarios such as exercise. Electric respiratory assistive devices are bulky and difficult to carry, their unidirectional airflow cannot match breathing rhythms, and their noise can disrupt sleep. Existing smart wearable nasal wearable devices are limited to monitoring functions, lacking active air purification and respiratory coordination control capabilities, thus failing to meet the comprehensive respiratory health needs in various scenarios. There is an urgent need for a smart wearable device that combines air purification, respiratory assistance, and health monitoring functions to meet respiratory health needs in different scenarios. To address these issues, this application provides a bidirectional turbofan nasal wearable device control method and a bidirectional turbofan nasal wearable device. For details, please refer to... Figure 1 The bidirectional turbofan nose-mounted device control method includes steps 101 to 104.

[0043] Before introducing the control method for the bidirectional turbofan nose-mounted device, it is necessary to introduce the bidirectional turbofan nose-mounted device to which this solution is applied:

[0044] The bidirectional turbofan nose-mounted device includes a sensor, a bidirectional turbofan, and pulsed stimulation electrodes.

[0045] Sensors are used to collect respiratory-related characteristic information (such as airflow velocity, intranasal pressure, temperature changes, etc.) to provide data support for respiratory phase identification. Possible implementations include, but are not limited to, miniature airflow sensors, pressure sensors, or infrared respiratory sensors. The specific principle of the sensor is not limited (such as piezoelectric, thermal, etc.), as long as it can effectively acquire respiratory characteristics.

[0046] A bidirectional turbofan is a miniature fan capable of switching between forward and reverse rotation, serving as the core actuator for controlling airflow direction. When in use, the bidirectional turbofan is placed inside the nasal cavity. In practical implementation, an ultra-miniature bidirectional turbofan system (fan diameter ≤ 8mm) can be used, employing a neodymium magnet brushless motor. It supports rapid forward and reverse rotation switching (switching time < 0.1s). The specific size and drive method of the fan are not limited as long as it meets the requirements for intranasal placement.

[0047] The pulse stimulation electrode is used to output a safe pulse signal during respiratory arrest. It can be placed against the nasal turbinate and stimulates the respiratory reflex arc with a low current (safe current <0.1mA). The specific shape of the electrode is not limited (such as sheet, wire, etc.), as long as it can stably contact the nasal turbinate and meets the biocompatibility requirements.

[0048] In actual implementation, the equipment may also include power supply components, switching components, and communication structures for communicating with user terminals, etc., which are not limited here.

[0049] When the bidirectional vortex fan nasal device is in use, the bidirectional vortex fan is placed inside the nasal cavity, and the pulse stimulation electrode is placed on the nasal turbinate.

[0050] The bidirectional turbofan needs to be adapted to the physiological structure of the nasal cavity to ensure that it can effectively guide outside air into or out of the nasal cavity without affecting normal breathing. Possible implementation methods include fixing it to the nasal vestibule with a flexible bracket or using an arc-shaped design that conforms to the curvature of the nasal passage. The specific fixing method is not limited (such as silicone adhesive), as long as portability and comfort are met. The pulse stimulation electrode needs to be in stable contact with the nasal turbinate mucosa to ensure effective transmission of the stimulation signal. It can be made of flexible material that conforms to the curvature of the nasal turbinate. The fixing position of the electrode is not limited (such as the middle turbinate or inferior turbinate), as long as it can trigger the respiratory reflex arc.

[0051] 101. Obtain sensor information.

[0052] The device uses built-in sensors to collect characteristic data of the breathing process in real time (such as airflow input velocity during inspiration, airflow output velocity during expiration, and airflow stillness during apnea). In actual implementation, a pressure sensor can be used to measure pressure direction, which is then used to determine the current respiratory phase. The sensor collects data at a preset frequency (such as 100Hz). In actual implementation, the data collection frequency is not limited, as long as the real-time requirement for respiratory phase recognition is met and respiratory characteristic information can be stably acquired and transmitted.

[0053] 102. Determine the current respiratory phase based on the sensor information, wherein the respiratory phase includes any one of the inspiratory phase, expiratory phase, and apnea phase;

[0054] In actual implementation, the device control chip can be preset with a "breathing phase recognition algorithm" to identify the phase by analyzing the airflow direction (airflow from outside to inside during inhalation, and from inside to outside during exhalation) or pressure change trend (nasal cavity pressure is lower than the external pressure during inhalation, and vice versa during exhalation). If the sensor data shows that the airflow velocity is 0 and continues for more than a preset time (e.g., 5 seconds), it is determined to be a stagnant phase. Based on the determination result, any one of steps 103, 104, and 105 is executed.

[0055] 103. Control the working airflow direction of the bidirectional turbofan to be from the outside to the nasal cavity.

[0056] Specifically, if the breathing phase is the inhalation phase, the working direction of the bidirectional turbofan is controlled to allow air to enter the nasal cavity from the outside. The control module outputs a positive drive signal to the bidirectional turbofan, causing it to operate at a preset wind speed and actively force outside air into the nasal cavity. In actual implementation, the wind speed of the bidirectional turbofan during the inhalation phase can be consistent with the change pattern of human inhalation wind speed, that is, from low speed to high speed and then back to low speed. In actual implementation, historical data of the user's breathing wind speed can be collected, and the bidirectional turbofan workflow can be established based on this historical data, that is, wind speed changes, duration of each breathing phase, etc., which are not limited here.

[0057] 104. Control the working airflow direction of the bidirectional turbofan to be from the nasal cavity to the outside.

[0058] Specifically, if the breathing phase is the exhalation phase, the working direction of the bidirectional turbofan is controlled to expel air from the nasal cavity to the outside. In actual implementation, the control module outputs a reverse drive signal to reverse the bidirectional turbofan at a preset wind speed of 0.3-0.8 m / s, actively expelling CO2 and waste gas from the nasal cavity and reducing exhalation resistance. In actual implementation, the wind speed of the bidirectional turbofan during the exhalation phase can be consistent with the change pattern of human exhalation wind speed, that is, from low speed to high speed and then back to low speed. In actual implementation, the user's historical breathing wind speed data can be collected, and the bidirectional turbofan workflow can be established based on this historical data, that is, wind speed changes, duration of each breathing phase, etc., which are not limited here.

[0059] 105. Control the pulse stimulation electrode to emit a pulse stimulation signal.

[0060] Specifically, if the respiratory phase is apnea, the pulse stimulation electrode is controlled to emit a pulse stimulation signal. The control module outputs a low-current pulse (safe current <0.1mA) to the pulse stimulation electrode, which stimulates the nerve endings in the nasal turbinate through electrical signal, awakens the respiratory reflex arc, and alleviates apnea.

[0061] As can be seen from the above technical solutions, the embodiments of this application have the following advantages: The embodiments of this application provide a control method for a bidirectional turbofan nasal device, including: the bidirectional turbofan nasal device includes a sensor, a bidirectional turbofan, and a pulse stimulation electrode; when the bidirectional turbofan nasal device is in use, the bidirectional turbofan is placed inside the nasal cavity, and the pulse stimulation electrode is placed on the nasal turbinates; the method includes: acquiring sensor information; determining the current respiratory phase based on the sensor information, the respiratory phase including any one of an inspiratory phase, an expiratory phase, and a stagnation phase; if the respiratory phase is an inspiratory phase, controlling the working airflow direction of the bidirectional turbofan to be from the outside to the nasal cavity; if the respiratory phase is an expiratory phase, controlling the working airflow direction of the bidirectional turbofan to be from the nasal cavity to the outside; if the respiratory phase is a stagnation phase, controlling the pulse stimulation electrode to emit a pulse stimulation signal. This solution determines the current respiratory phase (inspiratory, expiratory, or apnea) by acquiring sensor information and then controls the airflow direction of the bidirectional turbofan or the working state of the pulse stimulation electrode accordingly. During the inspiratory phase, the turbofan is controlled to draw air into the nasal cavity from the outside, actively pressurizing oxygen supply and improving oxygen supply efficiency, thus overcoming the shortcomings of traditional nasal canister products that lack active oxygen supply and have poor performance in exercise scenarios. During the expiratory phase, the turbofan is controlled to expel air from the nasal cavity to the outside, efficiently removing carbon dioxide and reducing expiratory resistance. When the respiratory phase is determined to be apnea, the pulse stimulation electrode is controlled to emit a pulse stimulation signal, which can respond to breathing apnea by activating the respiratory reflex arc, forming an active intervention for respiratory safety and making up for the deficiency of existing smart wearable nasal devices that can only monitor but not intervene.

[0062] In actual implementation, the method of use may also include:

[0063] 201. Determine the presence of snoring based on sensor signals;

[0064] The device collects physiological signals through built-in sensors, analyzes signal characteristics using algorithms, identifies the presence of snoring, and provides triggering conditions for subsequent interventions. The sensors can be acoustic or vibration sensors.

[0065] The system extracts key features from raw signals collected by sensors (such as the time-domain waveform of sound waves and the frequency spectrum of vibrations), including typical snoring frequencies (20-200Hz), amplitude thresholds (amplitudes higher than normal breathing vibrations), and duration (a single snoring sound typically lasts >0.5 seconds). These extracted features are compared to a pre-defined "snoring feature library" (generated through training with a large number of snoring samples). If the matching degree exceeds a threshold (e.g., 80%), snoring is detected. In some scenarios, the device can adaptively adjust feature thresholds based on long-term user data (e.g., the unique frequency of a user's habitual snoring) to better reflect individual differences. Alternatively, it can make judgments based on pre-defined rules, such as frequency and amplitude.

[0066] 202. If snoring is present, increase the efficiency of the bidirectional turbofan when the respiratory phase is the inspiratory phase.

[0067] When snoring is detected, the airflow is optimized by enhancing the turbine power of the inspiratory phase, which helps to alleviate snoring, reduce the probability of airway collapse, and reduce soft tissue vibration.

[0068] Specifically, increasing the efficiency of a bidirectional turbofan can improve airflow speed. For example, the default speed is 0.5-1.2 m / s, which can be increased in increments (e.g., +0.2 m / s each time, with an upper limit not exceeding the nasal comfort tolerance speed, such as 2 m / s). This actively pressurizes and delivers air to the nasal cavity, supporting the airway and reducing collapse vibration. It also improves response speed, shortening the turbofan's startup time from standby / low power to high power (e.g., from 0.1 seconds to 0.05 seconds), allowing airflow to replenish the inhalation phase earlier and more promptly, stabilizing the pressure within the airway.

[0069] The above solution can accurately and effectively alleviate snoring: by using sensors to identify snoring in real time and trigger targeted intervention, it only increases the efficiency of the bidirectional turbofan during the inspiratory phase (such as increasing wind speed and airflow pressure), and uses active air delivery to support the upper airway, reducing soft tissue collapse and vibration, thus directly improving the root cause of snoring from a physical level; at the same time, this "on-demand control" mode only starts efficient operation when snoring occurs, which avoids interference with normal breathing rhythm, adapts to the body's natural breathing cycle to ensure comfort, and reduces unnecessary energy consumption, extending the device's battery life. Compared with traditional intervention methods, it is more intelligent and less invasive, taking into account intervention effect, user experience and practicality.

[0070] In practical implementation, the two-way turbofan nose-worn device may also include a Bluetooth module for user control, specifically including:

[0071] 301. Accept mode selection commands sent by the user via the Bluetooth module.

[0072] Users select a target mode (sleep / exercise / pollution) through the terminal APP, and the command is sent to the device in the form of a Bluetooth signal; after the device control module parses the command, it calls the preset parameters of the corresponding mode (such as power threshold and turbo fan start / stop logic).

[0073] 302. Modulation of bidirectional turbofan nose-mounted device based on mode selection command.

[0074] Specifically, the modes may include: sleep mode, exercise mode, and pollution mode.

[0075] Sleep mode: Reduces the turbine power during the inhalation and exhalation phases, specifically by reducing the motor speed (e.g., reducing the inhalation phase airflow speed from 0.5-1.2m / s to 0.3-0.8m / s, and the exhalation phase airflow speed from 0.3-0.8m / s to 0.2-0.5m / s), thereby reducing airflow noise ("Sleep mode: low airflow + strong filtration") and improving sleep comfort.

[0076] Exercise mode: Increase the power of the turbofan during the inspiratory and expiratory phases, and increase the air volume by increasing the speed (e.g., the inspiratory phase air speed is increased to 0.8-1.5m / s, and the expiratory phase to 0.5-1.0m / s), thereby enhancing active oxygen supply and CO2 removal efficiency to meet the high respiratory demands during exercise.

[0077] Pollution mode: The turbofan stops operating actively (or maintains an extremely low speed), and prioritizes air purification by relying on the three-layer composite structure of the equipment's "nanofiltration system" (electrostatic nanofibers, activated carbon crystals, and antibacterial copper mesh), avoiding the impact of high-speed airflow on filtration efficiency.

[0078] In actual implementation, the device can also send sensor information to the user terminal based on the Bluetooth module. The sensor information includes any one or more of the following: respiratory rate, blood oxygen saturation, PM2.5 concentration, and formaldehyde concentration.

[0079] Wireless data interaction between the device and the user terminal is achieved via a Bluetooth module, synchronizing physiological and environmental data monitored by the device to the terminal, enabling visualization of health status and feedback of environmental information. The Bluetooth module uses a Bluetooth Low Energy (BLE) module (such as BLE 5.0 and above) to meet the miniaturization and low power consumption requirements of the device, ensuring stable communication in nasal wear scenarios (communication distance covers the daily use range, such as 0-10 meters). Respiratory rate is monitored in real time by the device's built-in airflow or pressure sensor, and calculated by the control module (e.g., breaths per minute). PM2.5 concentration and formaldehyde concentration are monitored in real time by the device's integrated gas sensor, directly acquiring environmental pollutant data. Sensor information is packaged and transmitted at a preset frequency (e.g., once every 1-5 seconds), or triggered for immediate transmission when abnormal fluctuations occur (e.g., PM2.5 concentration exceeds the standard); after receiving the data, the user terminal (e.g., a mobile APP) displays it in the form of charts, values, etc., supporting historical data storage and trend analysis.

[0080] The above content introduces the control method of the bidirectional turbofan nose-mounted device. The following section describes the bidirectional turbofan nose-mounted device provided in this solution; please refer to [link / reference needed]. Figure 4 This bidirectional turbofan nose-worn device is a smart wearable device integrating multiple functional components and adapted to specific control methods. Its core components include a sensor 401, a bidirectional turbofan 402, and a pulse stimulation electrode 403. In use, the bidirectional turbofan is placed inside the nasal cavity, and the pulse stimulation electrode is attached to the nasal turbinates, enabling the functions described above. Figures 1 to 3 The methods described (such as controlling the direction of the turbofan based on the respiratory phase, triggering pulse stimulation during respiratory arrest, etc.).

[0081] In terms of key component design, the equipment has several targeted features: a bidirectional micro fan with a diameter of 8mm and a thickness of 3.2mm, a noise level of <15dB, and a neodymium magnet brushless motor with a forward / reverse switching time of <0.1s. Equipped with a Venturi tube structure, the 30° inlet cone angle increases airflow speed by 20%, reducing eddy noise. This ensures efficient drive and rapid forward / reverse switching capabilities while optimizing airflow dynamics through the Venturi effect, improving air supply or exhaust efficiency. The nanofilter, a crucial auxiliary component, is composed of electrostatic nanofibers, activated carbon crystals, and antibacterial copper mesh. It achieves multi-level air purification, effectively filtering PM2.5, formaldehyde, and other pollutants and microorganisms, achieving a filtration efficiency of up to 99.97% and reducing breathing resistance by 40%. The pulse stimulation electrode uses flexible silver nanowire electrodes, possessing excellent biocompatibility and conductivity. It can precisely stimulate the nasal turbinates with a safe current (<0.1mA) to awaken the respiratory reflex arc. The sensor system integrates an infrared gas sensor, a VOC monitoring chip, and a differential pressure gauge, collecting multi-dimensional information such as respiratory rate, gas concentration, and pressure changes, providing data support for functions such as respiratory phase recognition and environmental monitoring.

[0082] The overall architecture of this solution can be referenced. Figure 5 This solution determines the current respiratory phase (inspiratory, expiratory, or apnea) by acquiring sensor information and then controls the airflow direction of the bidirectional turbofan or the working state of the pulse stimulation electrode accordingly. During the inspiratory phase, the turbofan is controlled to draw air into the nasal cavity from the outside, actively pressurizing oxygen supply and improving oxygen supply efficiency, thus overcoming the shortcomings of traditional nasal canister products that lack active oxygen supply and have poor performance in exercise scenarios. During the expiratory phase, the turbofan is controlled to expel air from the nasal cavity to the outside, efficiently removing carbon dioxide and reducing expiratory resistance. When the respiratory phase is determined to be apnea, the pulse stimulation electrode is controlled to emit a pulse stimulation signal, which can respond to breathing apnea by activating the respiratory reflex arc, forming an active intervention for respiratory safety, thus making up for the deficiency of existing smart wearable nasal devices that can only monitor but not intervene.

[0083] Overall, the device, through the coordinated design of its components, takes into account multiple functions such as breathing assistance, health monitoring, air purification, and abnormal intervention, and is suitable for use in various scenarios such as sleep and exercise.
