Core Technology

PSA Oxygen Production Technology

（1）Basic Principle
Pressure Swing Adsorption (PSA) oxygen production technology exploits the differences in adsorption properties of adsorbents for different gases, separating gases and producing oxygen by periodically varying the pressure. This technology exploits the differences in the adsorption capacity of molecular sieves for different gas molecules. Under a given pressure, molecular sieves adsorb nitrogen much more strongly than oxygen. When compressed air enters an adsorption tower equipped with a molecular sieve, nitrogen is adsorbed on the sieve surface, while oxygen is separated as the product gas. When adsorption reaches a certain level, the pressure is reduced (desorption), releasing nitrogen and other impurities adsorbed by the molecular sieve, regenerating the molecular sieve for the next round of adsorption and separation. By alternating the operation of multiple adsorption towers, continuous and stable oxygen production is achieved.

（2）System Components
Air pretreatment system: Includes equipment such as an air compressor, air buffer tank, degreaser, and dryer. The air compressor compresses ambient air, raising its pressure for subsequent adsorption and separation. The air buffer tank stabilizes the compressed air’s pressure. The degreaser removes oil from the compressed air. The dryer removes moisture from the compressed air to prevent it from affecting the molecular sieve’s adsorption performance.
Adsorption tower: The core equipment of the PSA oxygen production system, filled with molecular sieve adsorbent. Typically, at least two adsorption towers are used. A valve switches between them, allowing one adsorption tower to adsorb oxygen while the other desorbs and regenerates, alternating operation to ensure continuous oxygen production.
Valve control system: Consisting of various pneumatic or solenoid valves, it controls the flow of compressed air and oxygen according to a pre-programmed sequence, switching the adsorption towers between different process steps, such as adsorption, pressure equalization, desorption, and flushing.
Oxygen buffer tank: Stores the produced oxygen, stabilizes its pressure and flow, and reduces fluctuations in the output pressure and flow.

（3）Process Flow
Adsorption Phase: Pre-treated compressed air enters the adsorption tower. Under high pressure, the molecular sieve adsorbs impurities such as nitrogen and carbon dioxide. Oxygen flows out of the tower outlet as product gas and enters the oxygen buffer tank.
Pressure Equalization Phase: When an adsorption tower nears saturation, air intake is stopped and the tower is connected to another adsorption tower undergoing desorption to equalize the pressure between the two towers. This recovers some of the energy from the high-pressure gas, reducing energy consumption and also serves as a preliminary fill for the adsorption tower about to begin adsorption.
Desorption Phase: After pressure equalization is complete, the adsorption tower’s exhaust valve is opened to rapidly reduce the pressure within the tower. Nitrogen and other impurities adsorbed by the molecular sieve are desorbed from the adsorbent surface at low pressure and discharged from the system, restoring the molecular sieve’s adsorption capacity.
Flushing Phase: At the end of the desorption phase, a portion of the produced oxygen is used to flush the adsorption tower back into the adsorption tower to further remove impurities remaining in the adsorbent and ensure full regeneration of the molecular sieve for the next adsorption cycle. The adsorption tower then re-enters the adsorption phase, repeating this cycle for continuous oxygen production.

（4）Technical Features

High Purity: Through optimized processes and equipment, our machines can produce oxygen with a purity of approximately 90%-95%.
Relatively Low Energy Consumption: Compared to cryogenic oxygen production, PSA oxygen production consumes less energy for small- to medium-scale production. The primary energy consumption is concentrated in the air compression process, and the equipment operates stably with minimal fluctuations in power consumption.
Fast Startup: From startup to producing oxygen with a purity exceeding 90% of the required standard, it typically takes only 3 minutes. This allows for rapid response to user oxygen needs and allows for flexible start and stop operations at will.
Low Equipment Investment: Compared to cryogenic oxygen production equipment, PSA oxygen production equipment has a relatively simple structure, occupies a smaller footprint, and offers lower equipment investment costs.

International Intelligent AI Algorithm

（1）Millisecond-level Respiratory Signal Detection and Recognition
Multi-sensor fusion: The oxygen concentrator is equipped with a variety of high-precision sensors, such as pressure sensors and flow sensors, which monitor pressure changes and airflow velocity generated by the user’s breathing in real time. The pressure sensor can keenly detect pressure fluctuations in the nasal cavity during breathing, while the flow sensor accurately measures the flow of air in and out, collecting hundreds of sets of data per second.
Real-time AI algorithm analysis: An intelligent AI algorithm analyzes the massive amount of data collected by the sensors in real time, using pattern recognition technology to quickly and accurately identify the inhalation and exhalation phases. Through deep learning and feature extraction of respiratory waveforms, the algorithm adapts to individual user breathing habits, including respiratory rate (from the faster breathing rate of children to the relatively stable breathing rate of adults) and breathing depth. It accurately determines the user’s breathing status even when the user’s breathing state changes, such as shortness of breath after exercise.

（2）Millisecond-level Synchronized Pulse Oxygen Supply Control
Real-time calculation of oxygen delivery timing: After identifying the user’s inhalation signal, the AI ​​algorithm accurately calculates the optimal oxygen delivery time based on preset parameters and real-time monitoring data. Combined with continuous tracking and prediction of the respiratory cycle, the algorithm can pre-prepare oxygen, ensuring timely and accurate delivery to the respiratory tract the moment the user begins to inhale, achieving a millisecond-level synchronized response with a synchronization rate of up to 99.99%.
Pulse control strategy: The AI ​​algorithm controls the solenoid valve and other actuators within the oxygen machine to release oxygen in a pulsed manner. The pulse width and frequency are intelligently adjusted based on the user’s breathing needs. For users with weak breathing, the pulse width is appropriately increased to ensure sufficient oxygen delivery each time; for users with a faster breathing rate, the pulse frequency is increased to meet their continuous oxygen needs. This precise pulse control method avoids oxygen waste while providing users with an efficient oxygen inhalation experience.

（3）Dynamic adaptive adjustment
User habit learning: The AI ​​algorithm possesses machine learning capabilities. As the user uses the oxygen machine, it continuously analyzes the user’s breathing data and learns their breathing patterns and habits. With increased usage, the algorithm becomes more precise in understanding the user’s breathing characteristics, enabling increasingly personalized oxygen delivery plans. For example, after a period of use, the algorithm can automatically identify the different breathing needs of users when asleep and awake, and adjust the oxygen delivery strategy accordingly.
Environmental Adaptation: In addition to adapting to the user’s breathing, the algorithm also responds to changes in the usage environment. When factors such as ambient temperature and air pressure change (such as when used at high altitudes), the AI ​​algorithm automatically adjusts oxygen delivery parameters based on a built-in environmental parameter model, ensuring that the oxygen machine operates stably and efficiently in all environments, continuously providing the oxygen supply that meets the user’s needs.

（4）Algorithm Advantages and Significance
Improved Oxygen Utilization: By precisely tracking oxygen delivery with the human respiratory rhythm, unnecessary oxygen release during exhalation is largely avoided, significantly improving oxygen utilization. Compared to traditional continuous oxygen delivery methods, this method can conserve significant amounts of oxygen, reducing usage costs while also minimizing oxygen waste.
Improved User Experience: Oxygen delivery is tailored to the user’s real-time breathing status, making the oxygen inhalation process more natural and comfortable. This reduces discomfort caused by untimely or excessive oxygen delivery. This is particularly beneficial for patients requiring long-term oxygen inhalation, improving their compliance and quality of life.
Enhanced Device Intelligence: This AI algorithm empowers pulse oxygen machines with intelligent and personalized features, enabling them to better meet the diverse needs of different users.
