By converting blood oxygen saturation into a scoring value, the blood oxygen saturation scoring calculation model not only makes blood oxygen status assessment more intuitive and easier to understand, but also highlights the health hazards of low blood oxygen and enhances the sensitivity to dynamic changes. This provides doctors with real-time and accurate decision support, improving treatment efficiency.

[0200] It should be noted that the Kalman filtering process described above effectively removes noise from body temperature data, especially measurement errors that often accompany real-time monitoring. Kalman filtering extracts more accurate and stable body temperature information, avoiding interference caused by sensor errors or other external factors. Furthermore, Kalman filtering uses a state-space model to describe the body temperature change process, while combining it with a measurement model to correct the temperature estimate. It considers not only the sensor's measurement values ​​but also system dynamics (such as the trend of body temperature changes) to improve the estimate. Therefore, compared to traditional smoothing methods, it is more accurate and reflects reality. In addition, it has significant advantages in improving the real-time performance and accuracy of medical monitoring in complex or dynamically changing environments.

[0201] S242, process the first body temperature value to obtain the body temperature score value.

[0202] It should be noted that the initial body temperature value is processed to obtain a body temperature score, including:

[0207] It should be noted that the normal range for body temperature is 36.5℃-37.5℃, with 37℃ being the average of the normal range. The body temperature scoring model can directly convert body temperature into a score, making it easy for medical personnel or ordinary users to understand. It intuitively maps body temperature to a score range of 0-100, facilitating display and interpretation.

[0208] It is evident that implementing the medical evacuation system for search and rescue aircraft described in the embodiments of the present invention better adapts to rescue missions in various environments, helps meet the needs of transporting the wounded, and efficiently and accurately obtains the physiological parameters of the wounded, thereby playing an auxiliary role in improving the treatment rate of the wounded.

[0209] In an optional embodiment, the heart rate score, blood oxygen saturation score, respiratory rate score, and body temperature score are fused to obtain physiological parameter assessment values, including:

[0210] Using a physiological parameter fusion calculation model, heart rate score, blood oxygen saturation score, respiratory rate score, and body temperature score are fused to obtain physiological parameter evaluation values.

[0211] The physiological parameter fusion calculation model is as follows:

[0212] SLCS=δ4·HRSCORE+δ5·XYSCORE+δ6·HXSCORE+δ7·TWSCORE;

[0213] δ4+δ5+δ6+δ7=1;

[0214] 0.2≤δ4≤0.4;

[0215] 0.3≤δ5≤0.5;

[0216] 0.1≤δ6≤0.3;

[0217] 0.1≤δ7≤0.3;

[0218] In the formula, SLCS is the physiological parameter assessment value, HRSCORE, XYSCORE, HXSCORE and TWSCORE are the heart rate score, blood oxygen saturation score, respiratory rate score and body temperature score respectively, and δ4, δ5, δ6 and δ7 are the fourth weight parameter, the fifth weight parameter, the sixth weight parameter and the seventh weight parameter respectively.

[0219] It should be noted that the fourth, fifth, sixth, and seventh weight parameters can be set by the user or obtained from historical data. Specifically, this embodiment of the invention does not limit the specific weight parameters.

[0220] It should be noted that, since changes in heart rate can rapidly affect health status, the value range of the fourth weighting parameter can be set to [0.2, 0.4]; since changes in blood oxygen have a significant impact on health, especially in cases of hypoxia, this weight needs to be increased, and the value range of the fifth weighting parameter can be set to [0.3, 0.5]; respiratory rate is closely related to changes in body temperature, but compared to heart rate and blood oxygen saturation, its impact on health assessment is slightly lower, and the value ranges of the sixth and seventh weighting parameters can both be set to [0.1, 0.3].

[0221] It's important to note that different physiological parameters (such as heart rate, blood oxygen saturation, and body temperature) have varying degrees of impact on health. Setting weight ranges allows the model to better adapt to changes in various physiological signals. For example, changes in blood oxygen saturation typically have a significant impact on health, especially under hypoxic conditions, where blood oxygen saturation scores contribute significantly to overall health assessments; therefore, a higher weight can be assigned to blood oxygen. Conversely, while abnormal body temperature has a substantial impact on health, changes in body temperature are relatively slow, generally less rapid than changes in heart rate and blood oxygen saturation; therefore, its weight can be relatively lower.

[0222] It should be noted that by setting the value range for each weight, the contribution of each physiological parameter in health assessment can be adjusted more precisely, optimizing the flexibility, adaptability, and accuracy of the assessment model, and ensuring that the influence of each parameter is reasonably reflected in the comprehensive assessment of multiple physiological parameters. In particular, dynamically adjusting the weights according to the uniqueness of the parameters, their range, and the needs of practical applications can improve the model's accuracy in different scenarios, thereby enhancing the ability to analyze and process complex physiological data.

[0223] It should be noted that physiological parameter assessment values ​​can be used to evaluate an individual's health status. An example assessment method is as follows:

[0224] Normal: When the physiological parameter assessment value is greater than a certain normal threshold (e.g., 90 points), it indicates that the health status is good.

[0225] Mild adverse condition: When the physiological parameter assessment value is in a certain middle range (e.g., between 70 and 90 points), it indicates that there is a minor problem with the health condition that needs attention, but is not life-threatening.

[0226] Severe adverse condition: When the physiological parameter assessment value is below a certain threshold (e.g., below 70 points), it indicates that there may be a serious problem with the health condition and that immediate intervention is required.

[0227] It is evident that implementing the medical evacuation system for search and rescue aircraft described in the embodiments of the present invention better adapts to rescue missions in various environments, helps meet the needs of transporting the wounded, and efficiently and accurately obtains the physiological parameters of the wounded, thereby playing an auxiliary role in improving the treatment rate of the wounded.

It intuitively maps body temperature to a score range of 0-100, facilitating display and interpretation.

[0334] It is evident that implementing the medical evacuation data processing method for search and rescue aircraft described in the embodiments of the present invention is beneficial for efficiently and accurately obtaining physiological parameter information of the wounded, thereby playing an auxiliary role in improving the treatment rate of the wounded.

[0335] In an optional embodiment, the heart rate score, blood oxygen saturation score, respiratory rate score, and body temperature score are fused to obtain physiological parameter assessment values, including:

[0336] Using a physiological parameter fusion calculation model, heart rate score, blood oxygen saturation score, respiratory rate score, and body temperature score are fused to obtain physiological parameter evaluation values.

[0337] The physiological parameter fusion calculation model is as follows:

[0338] SLCS=δ4·HRSCORE+δ5·XYSCORE+δ6·HXSCORE+δ7·TWSCORE;

[0339] δ4+δ5+δ6+δ7=1;

[0340] 0.2≤δ4≤0.4;

[0341] 0.3≤δ5≤0.5;

[0342] 0.1≤δ6≤0.3;

[0343] 0.1≤δ7≤0.3;

[0344] In the formula, SLCS is the physiological parameter assessment value, HRSCORE, XYSCORE, HXSCORE and TWSCORE are the heart rate score, blood oxygen saturation score, respiratory rate score and body temperature score respectively, and δ4, δ5, δ6 and δ7 are the fourth weight parameter, the fifth weight parameter, the sixth weight parameter and the seventh weight parameter respectively.

[0345] It should be noted that the fourth, fifth, sixth, and seventh weight parameters can be set by the user or obtained from historical data. Specifically, this embodiment of the invention does not limit the specific weight parameters.

[0346] It should be noted that, since changes in heart rate can rapidly affect health status, the value range of the fourth weighting parameter can be set to [0.2, 0.4]; since changes in blood oxygen have a significant impact on health, especially in cases of hypoxia, this weight needs to be increased, and the value range of the fifth weighting parameter can be set to [0.3, 0.5]; respiratory rate is closely related to changes in body temperature, but compared to heart rate and blood oxygen saturation, its impact on health assessment is slightly lower, and the value ranges of the sixth and seventh weighting parameters can both be set to [0.1, 0.3].

[0347] It's important to note that different physiological parameters (such as heart rate, blood oxygen saturation, and body temperature) have varying degrees of impact on health. Setting weight ranges allows the model to better adapt to changes in various physiological signals. For example, changes in blood oxygen saturation typically have a significant impact on health, especially under hypoxic conditions, where blood oxygen saturation scores contribute significantly to overall health assessments; therefore, a higher weight can be assigned to blood oxygen. Conversely, while abnormal body temperature has a substantial impact on health, changes in body temperature are relatively slow, generally less rapid than changes in heart rate and blood oxygen saturation; therefore, its weight can be relatively lower.

[0348] It should be noted that by setting the value range for each weight, the contribution of each physiological parameter in health assessment can be adjusted more precisely, optimizing the flexibility, adaptability, and accuracy of the assessment model, and ensuring that the influence of each parameter is reasonably reflected in the comprehensive assessment of multiple physiological parameters. In particular, dynamically adjusting the weights according to the uniqueness of the parameters, their range, and the needs of practical applications can improve the model's accuracy in different scenarios, thereby enhancing the ability to analyze and process complex physiological data.

[0349] It should be noted that physiological parameter assessment values ​​can be used to evaluate an individual's health status. An example assessment method is as follows:

[0350] Normal: When the physiological parameter assessment value is greater than a certain normal threshold (e.g., 90 points), it indicates that the health status is good.

[0351] Mild adverse condition: When the physiological parameter assessment value is in a certain middle range (e.g., between 70 and 90 points), it indicates that there is a minor problem with the health condition that needs attention, but is not life-threatening.

[0352] Severe adverse condition: When the physiological parameter assessment value is below a certain threshold (e.g., below 70 points), it indicates that there may be a serious problem with the health condition and that immediate intervention is required.

[0353] It is evident that implementing the medical evacuation data processing method for search and rescue aircraft described in the embodiments of the present invention is beneficial for efficiently and accurately obtaining physiological parameter information of the wounded, thereby playing an auxiliary role in improving the treatment rate of the wounded.
