[0002] Aeromedical rescue refers to the activity of providing medical rescue using airplanes or other aircraft. It is usually used in emergency situations when land rescue cannot arrive quickly or when the patient needs to be transferred long distance and quickly to a place with professional medical facilities.

[0003] The Chinese patent with publication number CN118453274A discloses an aviation medical rescue unit that integrates a power supply system and an oxygen supply system. The power supply system is designed mainly based on the aircraft power supply parameters and the power supply characteristics of the medical system. It is used to connect the onboard power supply to the medical equipment and lighting in the medical system to ensure the vital signs monitoring and medical treatment services of the wounded during long flights.

The oxygen supply system provides two stable and continuous oxygen outputs to the oxygen supply mask and the emergency ventilator, while meeting the medical oxygen supply needs of two wounded. The medical system cooperates with the power supply system and the oxygen supply system to realize long-distance monitoring and treatment of the wounded during medical evacuation.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In order to solve the problem in the prior art that each oxygen supply device is not subjected to targeted equipment inspection before the aircraft takes off, which results in data failure and unavailability, please refer to Figure 1 and Figure 2 , this embodiment provides the following technical solutions: An aviation medical rescue system with integrated oxygen supply function, comprising: Oxygen supply equipment verification unit, used for: Confirm the oxygen supply equipment in aviation medical rescue and uniquely code each rescue equipment. After the unique coding is completed, the target oxygen supply equipment is obtained; Oxygen supply equipment detection unit, used for: Perform functional tests on the target oxygen supply equipment, and mark the target oxygen supply equipment that has passed the test as the standard oxygen supply equipment; Medical plan confirmation unit, used for: The oxygen supply method is confirmed according to the rescue scene situation, and the on-site oxygen supply plan is confirmed according to the oxygen supply method. After the on-site oxygen supply plan is confirmed, the oxygen supply plan data is obtained; Integrated oxygen monitoring unit for: Implement oxygen supply according to oxygen supply plan data, monitor the patient's vital signs in real time during oxygen supply implementation, generate adjustment instructions for oxygen supply equipment according to the patient's vital signs, and record the oxygen supply process in real time; Monitoring data visualization control unit for: The real-time recorded data of the oxygen supply process is converted into visual data, and the converted visual data is transmitted to the control terminal for display. Medical staff make real-time judgments and controls based on the displayed data at the control terminal.

[0024] Specifically, by formulating a detailed equipment function testing process through the oxygen supply equipment confirmation unit and the oxygen supply equipment testing unit, the standardization and regularization of the aviation medical rescue system can be promoted. The medical plan confirmation unit can optimize the utilization of medical resources and avoid waste and shortage of resources. The integrated oxygen supply monitoring unit can ensure the effective utilization of oxygen and avoid unnecessary waste. By comparing and judging the visualized data with the oxygen supply equipment adjustment instructions through the monitoring data visualization control unit, medical staff can adjust the oxygen supply equipment more accurately to ensure the safety of patients.

[0025] The oxygen supply equipment confirmation unit is also used for: Oxygen supply equipment in aviation medicine includes fixed oxygen cylinders, portable oxygen cylinders, breathing masks and ventilators; Each oxygen supply device is managed through a unified oxygen management system, which includes a regulator, oxygen pipeline, chemical oxygen generator and oxygen concentration monitor; Uniquely code and label fixed oxygen cylinders, portable oxygen cylinders, breathing masks and ventilators and regulators, oxygen lines, chemical oxygen generators and oxygen concentration monitors; The target oxygen supply equipment is obtained after the unique coding number.

[0026] Oxygen supply equipment detection unit is also used for: Before the aircraft takes off, the fixed oxygen cylinders, portable oxygen cylinders, breathing masks, ventilators, regulators, oxygen pipelines, chemical oxygen generators and oxygen concentration monitors shall be tested for equipment functions; Carry out appearance inspection, pressure inspection, leakage inspection and charge and discharge inspection on fixed oxygen cylinders; Perform visual inspection, pressure inspection, leak inspection and weight inspection on portable oxygen cylinders; Conduct integrity testing, seal testing and fit testing on respiratory masks; Perform pressure and process tests on ventilators; Conduct pressure regulation test and flow regulation test on the regulator; Conduct visual inspection and pressure maintenance inspection on oxygen pipelines; Perform activation and output tests on chemical oxygen generators; Perform calibration and response tests on oxygen concentration monitors; After all the equipment has passed the test, they will be marked as target oxygen supply equipment. The equipment that fails the test will be replaced or repaired until all the equipment passes the test.

[0027] Specifically, through a unified oxygen management system, various oxygen supply equipment can be efficiently managed and maintained to ensure that they are in good working condition. The unique coding number allows each device to be accurately tracked and managed, improving management efficiency. The equipment function test process ensures that all oxygen supply equipment undergoes a strict safety inspection before the aircraft takes off. Special tests on different equipment (such as charging and discharging tests on fixed oxygen cylinders, weight tests on portable oxygen cylinders, etc.) further improve the safety performance of the equipment. Replacing or repairing unqualified equipment can ensure that the entire system can work normally in an emergency and provide patients with a continuous and stable oxygen supply. Through the systematic equipment function test, problematic equipment can be discovered and repaired in a timely manner, avoiding waste of resources due to equipment failure. By formulating a detailed equipment function test process, the standardization and normalization of the aviation medical rescue system can be promoted, which will help improve the operating efficiency and service quality of the entire system and provide better medical protection for patients.

[0028] Preferably, since oxygen supply is extremely critical during aviation medical rescue, timely oxygen supply to patients directly affects the rescue effect, so the oxygen concentration needs to be accurately monitored. For this reason, the oxygen concentration monitor needs to be strictly calibrated before being put into use. Specifically, the oxygen concentration monitor is calibrated and responded to, including the following steps: Prepare the calibration gas sample and select oxygen gas with known concentration as the standard gas sample. Start the oxygen concentration monitor, allow it to run and reach a stable state, set calibration parameters and calibrate gas flow; A calibration gas sample is introduced into the oxygen concentration monitor through an oxygen pipeline, and a regulator is arranged on the oxygen pipeline to adjust the oxygen flow rate, and the flow rate of the calibration gas sample is adjusted to meet the preset requirements by adjusting the regulator; Obtain the oxygen concentration detection value detected within a preset time period, divide the preset time period into a plurality of first time interval units, obtain an oxygen concentration detection time value within each first time interval subunit, and obtain the oxygen concentration detection value detected within the preset time period based on the plurality of oxygen concentration detection time values ​​by the following formula: in, is the oxygen concentration detection value, is the oxygen concentration detection time value in the nth first time interval subunit, n is the number of first time interval units, Compare the oxygen concentration detection values ​​in multiple different preset time periods with the concentration values ​​of the standard gas sample, and calculate the deviation value using the following formula:

[0029] is the deviation value, is the concentration value of the standard gas sample, is the oxygen concentration detection value in the i-th preset time period, i is a positive integer less than or equal to m, m is the number of preset time periods and is a positive integer greater than 2, When the deviation value is greater than the preset deviation threshold, it is marked that the accuracy of the oxygen concentration monitor does not meet the requirements, and the oxygen concentration monitor is adjusted or repaired; Recalibrate the adjusted oxygen concentration monitor according to the above steps until the calibration result is qualified.

[0030] The principle and effect of the above technical solution are as follows: by preparing oxygen gas of known concentration as a standard gas sample in advance, after starting the oxygen concentration monitor, it is necessary to wait until the state is stable before starting the calibration process, so as to prevent the instability of the early oxygen pipeline transmission from affecting the calibration effect. After setting the calibration parameters and the calibration gas flow rate, the calibration gas sample is completely filled in the oxygen concentration monitor so that it can be fully detected. In order to ensure that the detected oxygen concentration detection value is the true and objective level of the oxygen concentration monitor, it is continuously detected within a preset time period, and the preset time period is divided into a first time interval unit to obtain a first time interval unit. Since the data obtained by the oxygen concentration monitor is real-time, the oxygen concentration detection time value in each first time interval unit is calculated respectively, and then calculated The oxygen concentration detection value is obtained by averaging, and multiple preset time periods are set. The multiple preset time periods may be discontinuous and are detected separately. The oxygen concentration detection values ​​in the multiple preset time periods are compared with the concentration values ​​of the standard gas samples, and the deviation value is calculated. If the deviation value is greater than the preset deviation threshold, it proves that the accuracy of the oxygen concentration monitor does not meet the standard and needs to be calibrated or repaired. After calibration or repair, recalibration is performed until the calibration is qualified. The above technical solution improves the calibration rate of the oxygen concentration monitor by detecting the qualification of the oxygen concentration monitor at different time nodes based on the detection time as the node, which can ensure that the oxygen concentration monitor can provide accurate monitoring data in the subsequent use process, so as to facilitate medical staff to accurately grasp the patient's oxygen supply situation.

[0031] In order to solve the problem that the oxygen supply method is not confirmed according to the actual situation on site, and the oxygen supply method is not adjusted according to the actual situation of the patient, resulting in poor oxygen supply effect, please refer to Figure 1 and Figure 2 , this embodiment provides the following technical solutions: Medical plan confirmation unit, including: Oxygen supply mode confirmation module, used for: Confirm the oxygen supply method based on the on-site situation on the aircraft. The on-site situation confirmation is based on the patient's condition, environmental factors and equipment availability; Oxygen supply methods include fixed oxygen supply, portable oxygen supply, high-altitude oxygen supply, ventilator oxygen supply, chemical oxygen generator oxygen supply and on-site oxygen production.

[0032] Oxygen supply plan confirmation module is used to: After the oxygen supply method is confirmed, the oxygen supply plan will be formulated; The oxygen supply plan is formulated by setting equipment parameters according to different oxygen supply equipment in the oxygen supply mode. The equipment parameters include oxygen flow, pressure and equipment type; After the equipment parameters are set, medical staff are assigned; Oxygen supply plan data is obtained based on the oxygen supply equipment corresponding to each patient, the parameters set for each oxygen supply equipment, and the medical staff corresponding to each oxygen supply equipment.

[0033] Specifically, the oxygen supply mode confirmation module can flexibly select the most appropriate oxygen supply mode according to the on-site conditions on the aircraft, including patient conditions, environmental factors and equipment availability. This flexibility ensures that the system can provide effective oxygen supply under different flight conditions and emergency medical situations. After the oxygen supply mode is confirmed, the oxygen supply scheme confirmation module can quickly formulate an oxygen supply scheme, including equipment parameter settings and medical staff allocation. This high efficiency helps to respond quickly in emergency situations and provide patients with timely oxygen treatment. Through precise equipment parameter settings, such as oxygen flow and pressure, the system can ensure the stability and accuracy of oxygen supply, thereby improving the treatment effect. It can allocate corresponding oxygen supply equipment and parameter settings to each patient according to their specific conditions and needs, and realize personalized oxygen treatment. This customized service helps to meet the treatment needs of different patients and improve the pertinence and effectiveness of treatment. Through reasonable medical staff allocation and equipment parameter settings, the system can optimize the utilization of medical resources and avoid waste and shortage of resources. This helps to improve the overall efficiency and reliability of the aviation medical rescue system. Through strict equipment parameter settings and medical staff allocation, the safety and reliability of oxygen supply are ensured. This helps to reduce medical risks caused by insufficient or unstable oxygen supply.

[0034] Integrated oxygen supply monitoring unit, including: Vital signs data monitoring module for: When oxygen is supplied to the patient according to the oxygen supply plan data, the patient's vital signs are monitored at the same time; Vital sign monitoring equipment includes ECG monitors, blood oxygen saturation monitors, and respiratory rate monitors; When monitoring the patient's vital signs, record the patient's vital signs monitoring data in real time; The vital signs monitoring data include heart rate, heart rhythm, electrocardiogram, blood pressure and heart rate variability data monitored by an electrocardiogram monitor; Blood oxygen saturation, oxygen saturation trend and body temperature data monitored by the blood oxygen saturation monitor; Respiratory rate and breathing pattern data monitored by a respiratory rate monitor; Finally, the patient's vital signs monitoring data are obtained.

[0035] Oxygen supply equipment real-time adjustment module, used for: Compare the patient's vital sign monitoring data with the normal vital sign data, and determine the patient's abnormal range based on the comparison results, wherein the normal vital sign data is retrieved from the database; Generate oxygen supply equipment adjustment instructions based on the patient's abnormal range; Oxygen supply equipment adjustment instructions include oxygen flow adjustment, ventilator support level adjustment, and oxygen supply strategy adjustment; After the adjustment instruction is generated, the oxygen supply implementation continues, and the process of oxygen supply implementation before and after the patient's adjustment is recorded in real time.

[0036] Specifically, by integrating the vital signs data monitoring module, the aviation medical rescue system can monitor the patient's heart rate, heart rhythm, electrocardiogram, blood pressure, heart rate variability, blood oxygen saturation, oxygen saturation trend, body temperature, respiratory rate and breathing pattern and other key vital signs data in real time. These data provide medical staff with timely patient status information, helping them to make accurate medical judgments quickly, thereby improving medical efficiency and safety. Combined with the oxygen supply plan data, the system can accurately control the oxygen supply to ensure that patients receive the most appropriate oxygen therapy support. This precise oxygen supply helps reduce medical risks caused by insufficient or excessive oxygen supply. Through an integrated system, the costs incurred by multiple examinations and repeated operations in traditional medical processes can be reduced. At the same time, accurate medical judgment and efficient resource management can also help reduce overall medical costs. Real-time monitoring and precise oxygen supply can help reduce patients' pain and discomfort during transfer and improve their comfort. By real-time monitoring of patients' vital signs and comparing them with normal signs, the system can quickly identify the abnormal range of patients. The ability of real-time monitoring and rapid comparison enables the medical team to respond quickly and adjust the oxygen supply equipment in time, thereby improving the efficiency of patient treatment. According to the abnormal range of patients, the system can generate specific oxygen supply equipment adjustment instructions, including oxygen flow adjustment, ventilator support level adjustment and oxygen supply strategy adjustment. This precise adjustment method can ensure that patients receive the oxygen treatment that best suits their current condition, improving the effectiveness and safety of treatment. By accurately adjusting the oxygen supply equipment, the system can ensure the effective use of oxygen and avoid unnecessary waste. Real-time monitoring and rapid response mechanism can help to promptly detect and deal with patients' abnormal conditions, thereby reducing potential risks.

[0037] In the above technical solution, the oxygen flow adjustment and oxygen supply strategy adjustment in the oxygen supply equipment adjustment instruction include the following steps: The electrocardiogram monitored by the electrocardiogram monitor is retrieved, and the values ​​of the R waves in the electrocardiogram are connected by a smooth curve to construct a respiratory characteristic curve, and the duration of the inhalation process and the exhalation process is obtained according to the respiratory characteristic curve; The degree of airflow limitation of the patient is determined according to the ratio of the duration of the inhalation process to the duration of the exhalation process, and the airflow limitation level is divided according to the degree of airflow limitation of the patient, and the airflow limitation level includes the first limitation level, the second limitation level and the third limitation level; When the ratio of the duration of the inhalation process to the duration of the exhalation process is 1:1.5~1:2, the airflow limitation level is the first level; when the ratio of the duration of the inhalation process to the duration of the exhalation process is 1:2~1:3, the airflow limitation level is the second level; when the ratio of the duration of the inhalation process to the duration of the exhalation process is greater than 1:3, the airflow limitation level is the third level; During the process of supplying oxygen to the patient through the breathing mask, the oxygen concentration value in the breathing mask is monitored in real time through the oxygen concentration monitor, and the oxygen flow value of the oxygen pipeline is obtained in real time based on the regulator; When the airflow limitation level is the first limitation level, the first oxygen supply flow strategy of the oxygen pipeline is adjusted by the regulator to supply oxygen at a first oxygen flow value until the oxygen concentration value in the breathing mask reaches the first oxygen concentration value; When the airflow limitation level is the second level, the second oxygen supply flow strategy of the oxygen pipeline is adjusted by the regulator to supply oxygen at a second oxygen flow value, and the oxygen humidity value is adjusted at the same time until the oxygen concentration value in the breathing mask reaches the second oxygen concentration value; When the airflow limitation level is the third limitation level, the third oxygen supply flow strategy of the oxygen pipeline is adjusted through the regulator to supply oxygen at the third oxygen flow value, and the oxygen humidity value is adjusted at the same time until the oxygen concentration value in the breathing mask reaches the third oxygen concentration value.

[0038] The principle and effect of the above technical solution are as follows: the electrocardiogram monitored by the electrocardiogram monitor can most intuitively grasp the patient's breathing condition and obtain the breathing characteristic curve. The duration of the inhalation process and the exhalation process can be obtained according to the breathing characteristic curve. In this way, by analyzing the patient's exhalation process and the inhalation process, it is possible to quickly grasp whether the patient is in a state of hypoxia. The slope of the point on the breathing characteristic curve can reflect the patient's breathing process. If the slope is positive, it indicates that the patient is exhaling. If the slope is negative, it indicates that the patient is inhaling. If the slope is 0, it indicates that the patient is in respiratory stagnation (at the end of inhalation or at the end of exhalation), and the change in the slope can determine whether the patient is changing from the inhalation process to the exhalation process, or from the exhalation process to the inhalation process. In this way, the duration of the patient's inhalation process and the duration of the exhalation process can be obtained, and the degree of airflow limitation of the patient can be judged according to the ratio of the duration of the inhalation process to the duration of the exhalation process. When the ratio is 1:1.5~1:2, it means that the duration of the inhalation process is slightly shorter than the duration of the exhalation process, and the degree of airflow limitation is low. When the ratio is 1:2~1:3, it means that the duration of the inhalation process is lower than the duration of the exhalation process, and the degree of airflow limitation is moderate. When the ratio is greater than 1:3, the duration of inhalation is seriously lower than the duration of exhalation, and the degree of airflow limitation is relatively serious. At the same time, combined with the oxygen concentration value of the breathing mask and the oxygen flow value of the oxygen pipeline, the current oxygen supply situation can be grasped.

[0039] If the patient is at the first restricted level, it means that although the patient has a slight hypoxia, it is not serious. The first oxygen supply flow strategy of the oxygen pipeline can be adjusted through the regulator, basically increasing the oxygen supply flow value until the oxygen concentration value in the breathing mask reaches the first oxygen concentration value, wherein the first oxygen concentration value can be pre-set, and the first oxygen concentration value matches the first restricted level. Through pre-data training and testing, it can be obtained that the patient's airflow limitation can be alleviated at the first oxygen concentration value and the oxygen supply can be increased.

[0040] If the patient is in the second-level restriction level, it indicates that the patient has moderate hypoxia. In this case, the effect of only adjusting the flow of the oxygen pipeline cannot meet the requirements of timely adjustment. It is necessary to appropriately increase the oxygen humidity value. Increasing the oxygen humidity value can improve the oxygen supply effect and oxygen absorption rate until the oxygen concentration value in the breathing mask reaches the second oxygen concentration value. As above, the second oxygen concentration value can also be pre-set and match the second-level restriction level.

[0041] If the patient is in the third level of restriction, it means that the patient's exhalation is severely blocked and there is a serious lack of oxygen. In this case, it is necessary to adjust the flow rate and oxygen humidity value of the oxygen pipeline at the same time until the oxygen concentration value in the breathing mask reaches the third oxygen concentration value. As above, the third oxygen concentration value can also be pre-set and match the third level of restriction.

[0042] The above technical solution, by combining the patient's inhalation duration and expiratory duration, classifies the patient's airflow limitation into levels, and adopts different oxygen supply strategies under different airflow limitation levels to improve the necessity and effect of oxygen supply. Through intelligent settings, it can ensure that the patient receives effective oxygen support in a timely manner.

[0043] In order to solve the problem that the existing technology does not integrate the data of the oxygen supply equipment on the aircraft and does not coordinate and adjust the oxygen supply equipment with the actual situation of the patient, which leads to poor effect of aviation oxygen supply function, please refer to Figure 1 and Figure 2 , this embodiment provides the following technical solutions: The monitoring data visualization control unit is also used for: Confirm the oxygen supply implementation process data recorded in real time before and after the patient is adjusted; After the data is confirmed, data preprocessing is carried out, which includes data cleaning, data conversion and data standardization; After data cleaning is completed, a visualization template is designed. The visualization template includes chart type, color change, label and unit; Map the cleaned data to the designed visualization template, and generate visualization data of charts, equipment and indicators according to the mapping rules; The visual data is transmitted to the control terminal for display. Medical staff analyze the visual data for abnormal conditions at the control terminal, and make a comparison between the analysis results and the oxygen supply equipment adjustment instructions. The oxygen supply equipment is adjusted and implemented according to the judgment results. After the adjustment is implemented, the patient's oxygen supply process continues to be recorded in real time and transmitted to the control terminal. Medical staff make judgments on the transmitted data on the control terminal.

[0044] Specifically, data cleaning can remove redundant, erroneous or inconsistent data and improve data availability. Data conversion and standardization can unify the format of data from different sources to facilitate subsequent analysis and processing. By designing visualization templates, medical staff can intuitively see various data and indicators in the oxygen supply process, making it easier to understand and analyze data. The reasonable design of chart types, color changes, labels and units makes the data display clearer and more intuitive. Visual data is directly transmitted to the control terminal, and medical staff can see the data and make judgments at the first time, which improves the timeliness and accuracy of decision-making. By comparing and judging the visualized data with the adjustment instructions of the oxygen supply equipment, medical staff can adjust the oxygen supply equipment more accurately to ensure the safety of patients. The oxygen supply process of patients is recorded in real time and transmitted to the control terminal, so that medical staff can monitor the status of patients in real time. Once an abnormal situation is found, medical staff can respond immediately and adjust the oxygen supply equipment to ensure that patients receive timely and effective treatment. The steps of data confirmation, preprocessing, visualization, analysis and adjustment implementation are closely combined to form a complete workflow, which enables medical staff to work more efficiently and reduce unnecessary repetitive work.
