Description

Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to a micro-pressure oxygen chamber control system and a control method thereof. Background Art

[0002] A micro-compression oxygen chamber, also known as a micro-hyperbaric oxygen chamber, is a health device that provides a specific oxygen concentration and atmospheric pressure environment. Its working principle is to increase the blood oxygen content and blood oxygen partial pressure of the human body by simulating a high-pressure environment, thereby improving the blood oxygen diffusion capacity and effectively improving the hypoxic state in the body. However, there is a coupling characteristic between the pressure and oxygen concentration in the existing micro-compression oxygen chamber, that is, changes in pressure will affect the stability of the oxygen concentration. Existing control methods often find it difficult to effectively deal with this coupling relationship, resulting in fluctuations in oxygen concentration when adjusting the pressure, affecting user experience and treatment effects. The control systems of some micro-compression oxygen chambers have a low degree of automation and require more manual intervention and operation, which not only increases the difficulty of use for users, but may also cause safety hazards due to improper human operation. The control systems of some micro-compression oxygen chambers lack intelligent monitoring and early warning functions and cannot monitor the operating status of the equipment and the user's physiological indicators in real time. This will result in the equipment failing or the user feeling unwell and being unable to be handled in time, affecting the treatment effect and safety.

[0066] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0067] Reference Figure 1 As shown, a micro-pressure oxygen chamber control system comprises:

[0068] Oxygen chamber operation monitoring module: The oxygen chamber operation monitoring module is used to monitor and obtain information data of the micro-pressure oxygen chamber in real time. The module uses a high-precision sensor array, including the operation status of the micro-pressure oxygen chamber itself, the air pressure value inside the oxygen chamber, the oxygen concentration in the oxygen chamber, and the vital signs of the user in the oxygen chamber. Through integrated heart rate monitoring and blood oxygen saturation detection, the vital signs of the user are monitored contactlessly.

[0069] The data processing and analysis module is electrically connected to the oxygen chamber operation monitoring module. By processing and analyzing the massive data collected by the oxygen chamber operation monitoring module in real time, the module can accurately identify the complex coupling relationship between air pressure and oxygen concentration, and dynamically adjust the control strategy to ensure that the internal environment of the oxygen chamber is always maintained in the best treatment state, effectively avoiding the user's physical discomfort caused by environmental changes. The module also has fault prediction and health assessment functions, which can warn of potential problems in advance and ensure the long-term stable operation of the equipment;

[0070] An execution control module, which is electrically connected to the data processing and analysis module, and is used to adjust the gas flow entering the oxygen chamber according to the output of the algorithm, and adopt a closed-loop feedback control mechanism to ensure that the actual air pressure value and oxygen concentration respond quickly and stabilize near the set value, and can be quickly adjusted even in the face of slight fluctuations in the external environment, thereby ensuring the stability of the treatment effect;

[0071] The user operation and feedback module is electrically connected to the oxygen chamber operation monitoring module, the data processing and analysis module, and the execution control module. It is designed with an intuitive and easy-to-use touch interface, which displays various operating parameters of the oxygen chamber and the user's vital signs data in real time. Medical staff can set parameters and select treatment modes through the touch screen. The system supports voice prompts and alarm functions, and provides timely feedback on abnormal situations or operating errors, thereby improving the convenience and safety of operation. In addition, the module also has data recording and export functions, which is convenient for subsequent treatment evaluation and scientific research analysis;

[0072] The safety and protection module is electrically connected to the user operation and feedback module. Once the system detects abnormal air pressure inside the oxygen chamber, excessive oxygen concentration, or abnormal vital signs of the user, the system will immediately start the emergency stop procedure, cut off the air supply and start the ventilation system to ensure that the equipment quickly returns to a safe state. At the same time, the module also has remote monitoring and alarm functions, which can send abnormal situations to medical staff's mobile phones or monitoring centers in real time to achieve rapid response and disposal, and fully protect the safety of equipment and users.

[0073] Reference Figure 2 As shown, the oxygen chamber operation monitoring module includes:

[0074] The status monitoring unit is the basis of the oxygen chamber operation monitoring module. The status monitoring unit is used to monitor the operating status of the micro-pressure oxygen chamber itself in real time. The unit not only monitors the opening and closing status of the equipment to ensure that the oxygen chamber works according to the predetermined program, but also goes deep into the various components of the oxygen chamber, including the oxygen supply system, pressure regulation system and ventilation system, to check in real time whether their working status is normal. Once any component is found to be abnormal or faulty, the status monitoring unit will immediately trigger the alarm mechanism, and quickly convey the fault information to medical staff through sound and light alarms, display prompts or remote notifications, so that maintenance measures can be taken in time to prevent the fault from expanding and affecting the treatment effect and user safety;

[0075] The air pressure monitoring unit is the key to ensuring the stability of the internal environment of the oxygen chamber. The air pressure monitoring unit is used to monitor the air pressure value inside the oxygen chamber in real time to ensure that the air pressure is maintained within the set safety range. The unit also has an air pressure over-limit alarm function. Once the air pressure exceeds the preset safety threshold, it will immediately trigger an alarm to prevent discomfort or injury to the user due to excessive or low air pressure;

[0076] Oxygen concentration monitoring unit is an important part of ensuring the therapeutic effect of the oxygen chamber. It is used to monitor the oxygen concentration value inside the oxygen chamber in real time to ensure that the oxygen concentration meets the treatment requirements. The unit also has an oxygen concentration over-limit alarm function. Once the oxygen concentration deviates from the preset range, an alarm will be issued immediately to remind medical staff to adjust the treatment parameters to ensure the treatment effect and the safety of the user;

[0077] The vital signs monitoring unit is used to monitor the vital signs of the user in the oxygen chamber in real time, including respiratory rate, body temperature, pulse and blood pressure.

[0078] Reference Figure 3 As shown, the data processing and analysis module includes:

[0079] Data preprocessing unit, the data preprocessing unit is used to preprocess the raw data received from the oxygen chamber operation monitoring module, including data cleaning, data normalization and data compression, to ensure the integrity and accuracy of the data, and to perform data normalization to convert data of different dimensions and ranges to the same scale to facilitate subsequent algorithm processing. Finally, data compression technology is used to reduce the burden of data storage and transmission, while retaining key information of the data as much as possible to improve processing efficiency;

[0080] The coupling relationship analysis unit is used to analyze the coupling relationship between the pressure and oxygen concentration in the oxygen chamber. The algorithm builds a model of the dynamic changes of oxygen and pressure. By combining historical data and real-time data, an accurate model of the dynamic changes of oxygen and pressure is built. The model can predict the changing trend of the internal environment of the oxygen chamber under different operating conditions, providing a scientific basis for the design of the control algorithm.

[0081] The control algorithm design unit is used to design and implement an algorithm for controlling the operation of the oxygen chamber based on the results of the coupling relationship analysis, aiming to automatically adjust the oxygen supply and pressure of the oxygen chamber according to the preset treatment goals and the current environmental status, so as to maintain the stability of the internal environment of the oxygen chamber and optimize the treatment effect;

[0082] The algorithm optimization and debugging unit is used to continuously optimize and adjust the control algorithm according to actual effect feedback and experimental data. Through a closed-loop optimization process, the performance and adaptability of the control algorithm are continuously improved to ensure the long-term stable operation of the micro-pressure oxygen chamber control system.

[0083] Reference Figure 4 As shown, the user operation and feedback module includes:

[0084] A data display unit, which is responsible for receiving data from the oxygen chamber operation monitoring module in real time, including but not limited to the air pressure value inside the oxygen chamber, oxygen concentration, the user's vital signs and the operating status of the device, and displaying them on the user interface in the form of graphics and numbers;

[0085] A control command input unit, which is used to allow an operator to input control commands through an interactive interface to adjust the operating parameters of the oxygen chamber, including setting target air pressure, oxygen concentration and treatment time;

[0086] The feedback and alarm unit is responsible for receiving feedback signals from other modules, displaying corresponding alarm information on the user interface, and alerting users through sound and light alarms and vibration prompts.

[0087] Reference Figure 5 As shown, the safety and protection module includes:

[0088] The abnormality detection unit is responsible for real-time monitoring of data from the oxygen chamber operation monitoring module and the user operation and feedback module to detect abnormal conditions, including abnormal air pressure, abnormal oxygen concentration, unstable vital signs of the user and equipment failure. Once these abnormal conditions are detected, the abnormality detection unit will immediately issue an alarm and prepare to trigger the subsequent emergency response mechanism;

[0089] The emergency stop control unit is used when the abnormality detection unit detects an abnormality. When the abnormality detection unit issues an alarm, the unit will respond quickly and the emergency stop control unit will immediately trigger the emergency stop mechanism, which will cut off the power supply or gas source of all equipment in the oxygen chamber that may aggravate the dangerous situation, including stopping oxygen supply, adjusting pressure balance and shutting down the ventilation system, so as to put the oxygen chamber into a relatively safe state as quickly as possible;

[0090] Fault recording unit, the fault recording unit is used to record the relevant information of each emergency stop event, including the time of occurrence, abnormality type and processing results. These data are of great value for subsequent accident analysis, equipment improvement and process optimization.

[0091] Reference Figure 6 As shown, a micro-pressure oxygen chamber control method, the control method is:

[0092] Before starting the micro-pressure oxygen chamber, the system first performs a comprehensive self-check procedure. This process involves checking all key components and equipment inside the oxygen chamber one by one, including but not limited to the oxygen supply system, pressure regulation system, ventilation system, monitoring system and emergency stop system. The system uses built-in sensors and status monitoring units to collect the start-up status, working current and temperature of each component in real time, and compares them with the preset normal range. Once any abnormality or fault alarm is found, the system will immediately display a warning message on the user interface and suspend the startup process, waiting for further processing by the operator. Only after confirming that all components are in normal condition will the oxygen chamber be allowed to enter the next operation stage;

[0093] After confirming that there is no problem with the equipment, the user enters the micro-pressure oxygen chamber according to the instructions and closes the door. The micro-pressure oxygen chamber enters the operating state and all monitoring units begin to work fully.

[0094] The status monitoring unit monitors the opening and closing status of the micro-pressure oxygen chamber, the working status of each component, and equipment failure alarms in real time. The air pressure monitoring unit and the oxygen concentration monitoring unit monitor the air pressure value and oxygen concentration value inside the oxygen chamber in real time respectively. The vital sign monitoring unit monitors the vital signs of the user in the oxygen chamber in real time, including respiratory rate, body temperature, pulse and blood pressure. Once an abnormality is found, the alarm mechanism is triggered immediately.

[0095] The data preprocessing unit cleans, normalizes and compresses the raw data received from the oxygen chamber operation monitoring module to eliminate noise, improve data quality and reduce storage requirements. The coupling relationship analysis unit analyzes the coupling relationship between the pressure and oxygen concentration in the oxygen chamber, and constructs a model of the dynamic changes of oxygen and pressure through an algorithm. The control algorithm design unit designs and executes an algorithm for controlling the operation of the oxygen chamber based on the results of the coupling relationship analysis, so as to solve the problem of user physical discomfort caused by the coupling relationship between pressure and oxygen concentration during the operation of the oxygen chamber.

[0096] The execution control module adjusts the gas flow entering the oxygen chamber according to the output of the control algorithm to keep the air pressure and oxygen concentration in the oxygen chamber stable;

[0097] The data display unit receives data from the oxygen chamber operation monitoring module in real time and displays it on the user interface in the form of graphics and numbers for medical staff to view. Medical staff enter control commands on the interactive interface through the control command input unit to adjust the operating parameters of the oxygen chamber. The feedback and alarm unit receives feedback signals from other modules and immediately displays corresponding alarm information on the user interface once an abnormal situation is detected.

[0098] As the core component of the safety and protection module, the anomaly detection unit continuously monitors the data streams from the oxygen chamber operation monitoring module and the user operation and feedback module to detect abnormal conditions. Once an abnormal condition is detected, the emergency stop control unit will immediately trigger the emergency stop mechanism to stop the operation of the oxygen chamber to protect the safety of the equipment and users. The fault recording unit records the relevant information of each emergency stop event, including the time of occurrence, abnormality type and processing results;

[0099] In order to ensure the continued effectiveness and adaptability of the control algorithm, the algorithm optimization and debugging unit continuously optimizes and adjusts the control algorithm based on actual effect feedback and experimental data.

[0100] The method by which the coupling relationship analysis unit constructs a model of dynamic changes in oxygen and pressure through an algorithm is:

[0101] Based on the oxygen chamber operation monitoring module, time series data is regularly obtained, and the data includes regular observation values ​​of oxygen concentration and pressure;

[0102] Taking oxygen concentration and pressure as endogenous variables, the information criterion was used to determine the optimal lag order of the model;

[0103] Based on the oxygen concentration and pressure observation data, a dynamic change model is constructed, in which the basic form of the model is:

[0104]

[0105] In the formula, O2 represents oxygen concentration, P represents pressure, c represents constant term, z represents lag order, t represents total number of samples, i represents the value of the i-th group in the sample, φ 11,i ,φ 12,i ,φ 21,i and φ 22,i is the coefficient of the endogenous variable to its own lagged value, ∈ o2,t and ∈ P,t represents the error terms for oxygen and pressure;

[0106] The model was fitted using the least squares method, and the dynamic relationship between oxygen concentration and pressure was predicted in the model by the lag order;

[0107] Check the properties of the residuals to ensure there is no autocorrelation, heteroskedasticity, and nonlinear relationships, and perform model stability tests.

[0108] The method for executing the control module to regulate and control the oxygen and pressure in the micro-pressure oxygen chamber is:

[0109] The execution control module first relies on the data collected in real time by the oxygen chamber operation monitoring module, which includes but is not limited to the oxygen concentration, air pressure, temperature, humidity and vital signs of the user in the oxygen chamber;

[0110] Based on the preprocessed data, the coupling relationship analysis unit uses the dynamic change model it constructs to make short-term and long-term predictions of the oxygen concentration and pressure in the micro-pressure oxygen chamber. This model takes into account the interaction and coupling relationship between multiple factors.

[0111] Based on the prediction results of the dynamic change model and multi-variable coordination as the control strategy, the influence of multiple variables will be comprehensively considered when adjusting the oxygen supply system and pressure regulation system of the oxygen chamber;

[0117] Compare the actual measured value with the set value and calculate the error value;

[0118] Prepare an evaluation report based on the error calculation results and accuracy standards.

[0119] The user operation and feedback module sets personalized treatment parameters according to the user's own health status and needs, including but not limited to target oxygen concentration, air pressure range, treatment duration, and monitoring thresholds of specific vital signs. The system automatically memorizes and saves personalized settings.
