It integrates home and portable oxygen generation, multi-parameter intelligent control, health data monitoring and innovative respiratory rehabilitation functions, providing COPD patients with a full-scenario respiratory support solution. Background Technology

[0002] Patients with chronic obstructive pulmonary disease (COPD) are highly dependent on oxygen concentrators, requiring their use in various settings, including at home and when out and about. However, traditional home oxygen concentrators have several limitations: their mechanical design is rigid and doesn't blend well with home environments, lacking a human-centered approach; they are bulky and poorly portable, failing to meet the oxygen needs of patients during outdoor activities; their functionality is limited, providing only basic oxygen production and lacking the ability to dynamically adjust oxygen therapy parameters based on the patient's physiological state, nor can they provide long-term monitoring and professional guidance; furthermore, they have poor adaptability to different environments, making it difficult to guarantee the effectiveness of oxygen therapy in special environments such as high altitudes or areas with air pollution. In addition, traditional oxygen concentrators have significant shortcomings in energy management, integration with other medical devices, and patient rehabilitation assistance, failing to provide COPD patients with comprehensive, accurate, and convenient oxygen therapy services. This invention addresses these pain points through modular design, intelligent sensing and algorithm integration, and innovative functional integration, improving the patient's oxygen experience and treatment outcomes. Summary of the Invention

The pollution response unit includes a PM2.5 / VOC sensor and a negative ion generator. The PM2.5 / VOC sensor is installed inside the air inlet, and the negative ion generator is integrated at the air outlet. When the sensor detects a pollution peak, the pollution response unit sends a signal to the central control module to increase the oxygen purity to 93% ± 3% and simultaneously activates the negative ion generator.

[0045] One specific embodiment of the present invention

[0046] 1. The working process of a home oxygen concentrator:

[0047] Ambient air enters the air intake module 41 through the air inlet 4 located on the lower side of the main body shell 3. After preliminary filtration, it is delivered to the air compression module 42 for pressurization. The pressurized air enters the valve switching and control module 31, which can guide the air into the adsorption tower in the separation module 32 according to a preset sequence. Under the action of molecular sieves, oxygen and nitrogen are separated. The enriched oxygen enters the oxygen storage and buffer module 33 for temporary storage, while the nitrogen is discharged from the main body shell 3 through the exhaust module 34.

[0048] Oxygen from the oxygen storage and buffer module 33 is delivered to the flow control and humidification output module 61. Simultaneously, a home-style humidification water tank 7, installed in the middle chamber of the main casing 3, can be easily drawn and refilled via a drawer-type structure. It is connected to the flow control and humidification output module 61 to humidify the oxygen. The humidified oxygen is then output through the home-style oxygen outlet 6 located on the right side of the main casing 3 for patient use.

[0049] The display screen 5, embedded in the upper part of the main casing 3 and arranged at an angle, is electrically connected to the oxygen generation module group. Patients can view and adjust parameters such as oxygen concentration and flow rate through the display screen. The storage drawer 8 at the bottom of the main casing 3 is physically isolated from the oxygen generation module group and can be used to store oxygen tubing and other accessories.

[0050] 2. How to use the portable oxygen concentrator 2:

[0051] The portable oxygen concentrator 2 is charged and powered by a built-in battery when placed in the charging compartment on top of the home oxygen concentrator via an adapter. When you need to go out, simply remove it from the charging compartment and it will operate independently using the built-in battery.

[0052] In use, press the switch 21 embedded on the top side of the portable casing 24 to start the device. Humidification water is added to the portable humidification tank 23 through the water inlet 25 on the side of the portable casing 24. The portable humidification tank 23 can be easily inserted and removed from the portable casing 24 via a pull-out / snap-on structure. Ambient air enters the oxygen generation submodule through the portable air inlet on the lower side of the portable casing 24. After air intake, compression, valve switching control, and separation, oxygen is enriched and temporarily stored in the oxygen storage and buffer submodule. Nitrogen is discharged from the corresponding exhaust port of the portable casing 24 through the exhaust submodule. The enriched oxygen is humidified by the flow control humidification output submodule and the portable humidification tank 23, and then output from the portable oxygen outlet 22 on the upper side of the portable casing 24. The patient connects the oxygen tube to this outlet for oxygen inhalation. Additionally, a waist belt can be threaded through the grooves on both sides of the portable casing 24 and fastened around the waist for easy carrying.

[0053] 3. Operation of Pulse Oxygen Clip 1 and its connection to a home oxygen concentrator

[0054] The pulse oximeter clip 1 can be placed in the wireless charging area on the top of the main body shell 3 for charging. When in use, insert your finger into the detection port 11 in the middle of the pulse oximeter clip shell 13. The detection probe of the pulse oximeter detection module built into the pulse oximeter clip shell 13 is positioned opposite to the detection port 11 to obtain the pulse oximeter data of the user's finger and transmit the data to the display area 12 on the outer surface of the pulse oximeter clip shell 13 for real-time display.

[0055] Meanwhile, the pulse oximeter clip 1 establishes a communication connection with the central control module of the home oxygen concentrator via Bluetooth or Wi-Fi wireless communication, transmitting the detected blood oxygen data to the home oxygen concentrator in real time. Based on the received blood oxygen data, the home oxygen concentrator uses its built-in AI algorithm model to adjust the oxygen output, oxygen concentration, and oxygen flow rate in real time. When the blood oxygen data is abnormal, the display area 12 of the pulse oximeter clip 1 will display a prompt, and the display screen 5 of the home oxygen concentrator will also issue an alarm.

[0057] Dynamic Oxygen Therapy Optimization System: The respiratory monitoring unit integrates three sensors—a microphone, a piezoelectric film, and a millimeter-wave radar—installed inside the oxygen concentrator's casing close to the user's breathing area. These sensors collect real-time data on respiratory rate, tidal volume, and blood oxygen saturation, transmitting this data to the AI ​​adjustment unit via a data bus. The AI ​​adjustment unit has a built-in trained AI algorithm model that automatically adjusts oxygen flow and concentration based on the received respiratory data. During nighttime sleep mode, it identifies sleep apnea events and triggers pulsed oxygen delivery. The pathology model unit constructs a digital twin model based on pre-recorded patient medical history. Using reinforcement learning algorithms, it predicts the risk of acute exacerbations and transmits the risk signal to the AI ​​adjustment unit to adjust parameters in advance or directly trigger an alarm on the oxygen concentrator's display screen.

[0058] Intelligent Environmental Integration System: The environmental sensing unit's built-in air pressure sensor is installed on the core control board inside the oxygen generator. The GPS module is integrated into the antenna area on the top of the main casing. It accesses meteorological API data via a wireless module to acquire real-time environmental air pressure, geographical location, and meteorological parameters, transmitting the data to the air pressure compensation unit and pollution response unit. The air pressure compensation unit automatically calculates the oxygen partial pressure compensation curve based on the environmental air pressure data and sends parameter adjustment commands to the oxygen generation core module. The PM2.5 / VOC sensor in the pollution response unit is installed inside the air inlet. When a pollution peak is detected, it sends a signal to the oxygen generation module to increase the oxygen purity to 93% ± 3%, and simultaneously activates the negative ion generator integrated at the air outlet.

[0059] Medical-grade health central nervous system: The vital signs extension unit is equipped with a standard data interface, which connects to the ECG patch and non-invasive hemoglobin detection module via wired or wireless means to transmit the collected cardiovascular indicators and hemoglobin data to the health analysis unit. The health analysis unit communicates with the vital signs extension unit and the blood oxygen detection module, and uses AI algorithms to cross-analyze the correlation between hypoxia data and cardiovascular indicators, automatically generating reports and storing them in local memory. The drug coordination unit has a built-in respiratory system drug knowledge graph database, which is connected to the health analysis unit.

It has a built-in electricity price period recognition module, which sends a command to the molecular sieve control module to initiate a deep regeneration program during off-peak electricity periods or when solar power generation is sufficient, reducing energy consumption by 30%. Emergency Oxygen Supply Unit: The PEM electrolyzer and energy storage battery pack are installed in an independent chamber at the bottom of the main casing 3, connected to the power failure detection module of the main control board. In the event of a power failure, the AI ​​energy allocation algorithm controls the energy storage battery to supply power to the PEM electrolyzer, decomposing backup distilled water to produce oxygen. After treatment by the catalytic purification module, the oxygen is delivered to the oxygen outlet.

[0062] The collective intelligence network system employs a differential privacy processing module in its data sharing unit to anonymize user blood oxygen data before uploading it to the regional health cloud platform via a 5G module. This data is then combined with meteorological data to generate a respiratory disease risk map. The device collaboration unit, based on a federated learning framework, establishes a local wireless communication network with surrounding oxygen concentrators of the same type, sharing a database of device fault characteristics. When a local molecular sieve is detected as about to fail, maintenance warning information is pushed to surrounding intelligent oxygen concentrators and mobile control terminals such as smartphones and computers via a broadcast protocol.
