Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a closed-loop adaptive hydrogen-oxygen mixture supply control system and method. Background Technology

[0002] Hydrogen-oxygen mixed inhalation technology is increasingly widely used in the medical and health management fields. The human body requires a higher proportion of oxygen during respiration, but existing hydrogen-oxygen supply equipment has many shortcomings and cannot meet the personalized, safe, and intelligent needs of clinical practice.

[0003] 1. The hydrogen and oxygen supply architecture is unreasonable: Existing equipment mostly adopts a single gas generation module or a large-capacity hydrogen storage design, which either cannot meet the high oxygen demand of the human body or poses serious safety hazards. In addition, the continuous operation of the hydrogen generation module leads to energy waste and high manufacturing costs.

[0004] 2. Insufficient accuracy in proportioning adjustment: The flow regulation components of existing equipment are mostly general-purpose valves, lacking a special design for hydrogen-oxygen mixed gas supply. This results in problems such as cross-flow, slow response, and low adjustment accuracy. Furthermore, there is no adaptive adjustment mechanism linked to human physiological state, leading to poor adaptability.

[0005] 3. Poor gas supply stability: Hydrogen and oxygen gases are mostly directly mixed before output without an independent mixing buffer structure. Fluctuations in the output of dual-source equipment lead to uneven concentration of the mixed gas, affecting the performance.

[0006] 4. Disconnection between monitoring and control: Most equipment lacks non-contact vital sign monitoring function, or the monitoring data and gas supply regulation do not form a closed loop, relying on manual experience to adjust the ratio, resulting in low level of intelligence;

[0007] 5. Inadequate safety protection system: The design for preventing cross-contamination, hydrogen embrittlement, and emergency handling of hydrogen-oxygen mixed gas supply is insufficient. At the same time, it lacks full-cycle data management functions, which is not conducive to health management and solution optimization.

[0008] Therefore, there is an urgent need for a hydrogen-oxygen mixture gas supply system that is suitable for the human body's high oxygen demand, safe and energy-saving, intelligent and stable, and has a wide protection range, in order to solve the core defects of existing technologies. Summary of the Invention

[0009] The present invention aims to at least improve one of the technical problems existing in the prior art. To this end, the present invention proposes a closed-loop adaptive hydrogen-oxygen mixture supply control system and method thereof.

[0010] The technical solution of the present invention is as follows:

[0011] A closed-loop adaptive hydrogen-oxygen mixture supply control system integrates eight core modules to construct a fully closed-loop control system encompassing "monitoring-decision-supply-mixing-protection-management," with the specific structure as follows:

[0012] Wireless Non-Contact Monitoring Module: This innovative module utilizes non-contact sensing technology and wireless transmission to collect vital signs such as heart rate, respiratory rate, and blood oxygen saturation, penetrating obstacles like clothing. It eliminates the need for direct contact with the human body, avoiding discomfort and interference. Data transmission is wireless, resulting in low latency and strong anti-interference capabilities, ensuring accurate real-time data for gas supply adjustment and overcoming the drawbacks of traditional contact-based monitoring and wired transmission. The module employs sensing technologies including, but not limited to, microwave radar sensing and optical sensing, which can be flexibly adapted to different application scenarios.

[0013] Dual-Source Coordinated Gas Supply Module: This module innovatively adopts a dual-source architecture of a miniaturized hydrogen generation unit and a continuous oxygen supply unit, precisely matching the high oxygen requirements of human respiration. The miniaturized hydrogen generation unit, based on water electrolysis technology, is compact and has a moderate capacity. It can dynamically start and stop according to actual hydrogen supply needs, avoiding energy waste caused by continuous operation. It is equipped with an electrode self-cleaning component that periodically removes deposits from the electrode surface through reverse pulse current and other methods. Simultaneously, it is paired with a water quality monitoring component to monitor the resistivity of electrolyzed water in real time, ensuring stable hydrogen purity. The continuous oxygen supply unit, as the primary oxygen source, continuously produces high-purity oxygen. Equipped with an oxygen purity regulation component, it ensures that the oxygen purity meets usage requirements by dynamically adjusting adsorption pressure and other methods, working in synergy with the miniaturized hydrogen generation unit to meet the gas requirements of human respiration.

[0014] Small-capacity hydrogen storage unit: This miniaturized unit stores excess hydrogen produced by a smaller hydrogen generator, avoiding the safety risks associated with large-capacity hydrogen storage while reducing manufacturing costs and size. Linked with a pressure monitoring module, the unit stops hydrogen production when the internal pressure reaches a preset threshold; when the pressure falls below the threshold and there is a demand for hydrogen, it restarts production, achieving on-demand hydrogen buffering and balancing supply continuity and safety.

[0015] The self-designed proportional control module, as the core regulating component of the system, includes two independent flow regulation components, connected in series in the hydrogen supply circuit and the oxygen supply circuit respectively. The flow regulation components include, but are not limited to, proportional valves and servo valves, specifically designed for hydrogen-oxygen mixed gas supply scenarios. It incorporates a built-in flow feedback component and an integrated drive module, directly receiving control commands from the AI ​​closed-loop control module, offering fast response and high regulation accuracy. It adopts a dual-path collaborative feedback structure, including dual independent sealed valve cores and a built-in flow sensing component. The dual valve cores achieve synchronous regulation through mechanical coupling, ensuring the hydrogen-oxygen ratio accurately follows the target value. An anti-cross-gas isolation structure and self-cleaning function are added. The anti-cross-gas isolation structure uses an inert gas isolation chamber and a composite sealing ring design to prevent cross-contamination between hydrogen and oxygen. The self-cleaning function is achieved through a built-in ultrasonic vibration component, periodically removing impurities and condensate from the flow channel to prevent blockage. Simultaneously, it incorporates overcurrent, overpressure, and overheat protection components to meet the safety requirements of hydrogen-oxygen mixed gas supply.

[0016] Independent Mixing Buffer Module: This module features a mixing container independent of the dual-source co-supply module and the proportional control module, equipped with agitator mixing components (including but not limited to baffles, stirring components, and airflow disturbance units). The hydrogen and oxygen output from the dual-source equipment, after proportional adjustment, first enter the mixing container, where they are thoroughly mixed by the agitator mixing components, effectively eliminating concentration unevenness caused by fluctuations in output from a single device. The mixing container is connected to the preceding and following modules via pipelines, forming an independent mixing buffer, ensuring a stable and uniform concentration of the mixed gas delivered to the user, thus improving safety and comfort.

[0017] Multi-level safety protection modules: Constructing a full-chain safety protection system for "hydrogen production-hydrogen storage-hydrogen supply-mixing," including pressure monitoring components, hydrogen leak detection components, and emergency control components. The pressure monitoring component monitors the pressure status of small-capacity hydrogen storage units, mixing containers, and gas transmission pipelines in real time, with high accuracy and fast response; the hydrogen leak detection component uses high-sensitivity sensors to monitor the hydrogen concentration in the operating environment in real time, ensuring early detection of leaks; the emergency control component works in conjunction with other modules to immediately trigger protection mechanisms when hydrogen leaks, abnormal pressure, or substandard water quality are detected, including adjusting the opening of flow regulation components to maintain basic oxygen supply, controlling the shutdown of miniaturized hydrogen generator units, issuing audible and visual alarms, and recording fault information, thus mitigating safety risks at the source.

[0018] The AI ​​closed-loop control module, as the core control unit of the system, is electrically connected to other modules and has built-in parameter recognition and ratio optimization models. Based on real-time vital sign parameters collected by the wireless non-contact monitoring module, combined with historical gas supply schemes and parameter changes stored in the full-cycle health management module, it dynamically optimizes the hydrogen-oxygen flow ratio through intelligent algorithms, generates precise control commands, and sends them to the proportional regulation module and the dual-source collaborative gas supply module. This achieves fully closed-loop adaptive control of "monitoring-decision-adjustment-feedback," ensuring precise matching of gas supply parameters to human needs without manual intervention. It also features scene recognition and adaptation capabilities, automatically adjusting control strategies according to different usage scenarios.

[0019] The full-cycle health management module features gas supply parameter storage, historical protocol tracking, multiple protocol presets, and health data management. It records the hydrogen-oxygen ratio, flow rate, usage duration, and corresponding vital sign parameters for each use, supporting data export for health management analysis. Multiple commonly used ratio protocols are preset to meet the need for rapid switching in different scenarios. It also supports long-term management of user health data, providing data support for subsequent treatment plan optimization and multi-center clinical research, overcoming the shortcomings of traditional equipment data management.

[0020] Cross-scenario adaptation modules: Adopting a pluggable modular design, including but not limited to respiratory disease adaptation components, cardiovascular disease adaptation components, and home-based health care adaptation components. Different adaptation components are optimized for specific scenarios. For example, the respiratory disease adaptation component adds airway pressure compensation, while the home-based health care adaptation component optimizes energy consumption and ease of operation. Users can quickly switch between them according to their usage scenarios, enabling a single device to cover the needs of multiple scenarios such as medical, home, and rehabilitation, without the need for targeted device customization, thus improving device adaptability and practicality.

[0021] A closed-loop adaptive hydrogen-oxygen mixture supply control method, which uses the above-mentioned system to provide a closed-loop adaptive hydrogen-oxygen mixture to the human body, includes the following steps:

[0022] S1: After the wireless non-contact monitoring module is started, it collects human vital signs parameters through non-contact sensing technology. After preprocessing by anti-interference algorithms such as Kalman filtering, the data is sent to the AI ​​closed-loop control module through wireless transmission.

[0023] S2: The AI ​​closed-loop control module analyzes real-time vital signs parameters through a parameter recognition model, combines historical gas supply data and preset schemes stored in the full-cycle health management module, and outputs a suitable target hydrogen-oxygen ratio and corresponding flow control commands through a ratio optimization model.

[0024] S3: The dual-source coordinated gas supply module responds to control commands. The continuous oxygen supply unit continuously outputs high-purity oxygen, and the miniaturized hydrogen generation unit starts and stops producing hydrogen as needed according to the target hydrogen supply. The excess hydrogen produced is stored in a small-capacity hydrogen storage unit. The pressure monitoring component collects the hydrogen storage pressure in real time and feeds it back to the AI ​​closed-loop control module. When the pressure reaches the preset upper limit, the miniaturized hydrogen generation unit is controlled to stop producing hydrogen. When the pressure is lower than the preset lower limit, hydrogen production is started.

[0025] S4: The two sets of flow regulation components of the self-designed proportional regulation module regulate the output flow of hydrogen and oxygen according to the instructions, ensuring that the two gases are accurately delivered to the independent mixing buffer module in the target ratio;

[0026] S5: After hydrogen and oxygen gas enter the independent mixing container, the disturbance mixing component is activated to fully disturb and mix the gas, eliminate concentration fluctuations, and make the mixed gas concentration uniform and stable before being delivered to the human body through delivery components such as nasal cannulas.

[0027] S6: The hydrogen leak detection and pressure monitoring components of the multi-level safety protection module work continuously, providing real-time feedback of monitoring data. The AI ​​closed-loop control module compares the actual gas supply ratio with the target ratio in real time, and dynamically optimizes the flow regulation command in combination with the safety monitoring signal to ensure stable and safe gas supply. If an abnormal state is detected, the emergency control component will immediately trigger the protection mechanism.

[0028] S7: The full-cycle health management module records the current hydrogen-oxygen ratio, flow rate, usage time, and corresponding vital signs parameters, repeating S1 to S6 to achieve a closed-loop adaptive supply and exhaust control process for the hydrogen-oxygen mixture.

[0029] Beneficial effects of the present invention

[0030] 1. Innovative dual-source collaborative architecture: It adopts the design of "miniaturized hydrogen generation unit + continuous oxygen supply unit" to accurately adapt to the high oxygen demand of human breathing. The hydrogen generation unit starts and stops on demand and cooperates with small-capacity hydrogen storage, while the oxygen generation unit continuously supplies gas, taking into account energy saving, safety and gas supply stability, while reducing equipment size and manufacturing cost, breaking through the limitations of traditional single large-capacity equipment or fixed ratio equipment.

[0031] 2. Innovative self-designed proportional adjustment module: Specifically designed for hydrogen-oxygen mixed gas supply scenarios, it integrates functions such as dual-path collaborative feedback, anti-cross-flow, self-cleaning, and safety protection. It features high adjustment accuracy, fast response, and strong safety, solving the problem of poor compatibility of general valves and forming a core technology barrier.

[0032] 3.

Innovative end-to-end safety protection: Integrating multiple safety designs such as small-capacity hydrogen storage, leak detection, pressure monitoring, and emergency response, it avoids risks throughout the entire chain from hydrogen production to gas supply, while maintaining basic oxygen supply under abnormal conditions, significantly improving safety;

7. A closed-loop adaptive hydrogen-oxygen mixture supply control method, characterized in that, The system described in any one of claims 1 to 6 comprises the following steps: S1: After the wireless non-contact monitoring module is started, it wirelessly collects human vital signs parameters, and transmits them to the AI ​​closed-loop control module after anti-interference preprocessing. S2: The AI ​​closed-loop control module analyzes real-time vital signs parameters through intelligent algorithms, combines historical gas supply data and preset schemes stored in the full-cycle health management module, and outputs the target hydrogen-oxygen ratio and corresponding flow control commands. S3: The dual-source coordinated gas supply module responds to commands, the continuous oxygen supply unit continuously outputs oxygen, the miniaturized hydrogen generation unit starts and stops producing hydrogen as needed according to the target hydrogen supply, the surplus hydrogen is stored in the small-capacity hydrogen storage unit, and the pressure monitoring component provides real-time feedback on the hydrogen storage pressure. S4: The self-designed proportional control module uses two sets of flow control components to regulate the output flow of hydrogen and oxygen respectively, ensuring that the two gases are delivered to the independent mixing buffer module in the target ratio; S5: The independent mixing buffer module promotes the full mixing of hydrogen and oxygen gas by disturbing the mixing components, and outputs it to the human body after eliminating fluctuations; S6: The multi-level safety protection module monitors hydrogen leakage and system pressure status in real time, and the AI ​​closed-loop control module compares the actual ratio with the target ratio and dynamically optimizes the adjustment parameters; S7: The full-cycle health management module records the current gas supply parameters and vital signs data, repeating S1 to S6 to achieve closed-loop adaptive gas supply control.

8. The closed-loop adaptive hydrogen-oxygen mixture supply control method according to claim 7, characterized in that, In S3, when the pressure of the small-capacity hydrogen storage unit reaches the preset threshold, the AI ​​closed-loop control module sends a stop command, and the miniaturized hydrogen generator unit stops producing hydrogen; when the pressure is lower than the preset threshold and there is a demand for hydrogen supply, the miniaturized hydrogen generator unit starts producing hydrogen to ensure that hydrogen is supplied on demand and avoids ineffective hydrogen production and energy waste.
