Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of pressure compensation control, in particular to a dynamic compensation device for simulating high-altitude pressure self-adaptation for first aid of wounded persons. Background Art
[0002] In high-altitude environments, air pressure will change dramatically with the rapid increase or decrease in altitude. Traditional airway bags are difficult to maintain stable pressure under such rapid pressure changes, and most existing airway bag devices use fixed pressure setting thresholds or simple manual adjustment methods. They are unable to perceive the rapid changes in high-altitude pressure in real time and automatically make corresponding adjustments. Different target users have individual differences due to factors such as age, physical condition, and underlying diseases, and their tolerance range and requirements for airway bag pressure are also different. However, traditional airway management methods often use a unified airbag pressure standard, which does not fully consider that the individual physiological changes of the target users will also affect the optimal value of the airway bag pressure. Existing airbag devices are unable to monitor the physiological information of the injured in real time and adjust the airbag pressure accordingly.

[0119] Specifically, the ambient pressure prediction unit calculates the average absolute error to measure the degree of error between the pressure prediction value output by the ambient pressure prediction model and the actual high-altitude pressure, thereby evaluating the accuracy of the ambient pressure prediction model. The ambient pressure prediction unit also judges whether the average absolute error meets the standard. In this embodiment, 0.25≤MAE0≤0.5 is set to avoid frequent triggering of adjustments due to small pressure fluctuations, such as when MAE0<0.2, thereby reducing misjudgment and maintaining the stability of error adjustment.

In the early stage of the abnormal pressure change acceleration, the preset absolute error average value is quickly reduced to quickly update the preset absolute error average value. In the later update trend, the acceleration coefficient is set to match the change trend, so as to reasonably avoid the pressure change acceleration changing too fast and affect the accuracy of the environmental pressure prediction model, thereby improving the accuracy of the environmental pressure prediction model.

The preset probability value refers to a preset value for judging whether the final probability value meets the standard. The compliance status of the final probability value refers to the degree of compliance of the final probability value determined based on the final probability value and the preset probability value. The compliance status of the final probability value includes the following: the final probability value meets the standard and the final probability value meets the standard.
[0134] Specifically, the pressure dynamic compensation unit obtains the airway airbag safety dynamic compensation interval according to the individual characteristics of the target user through a generator. In this embodiment, the preset probability value is set to 80%≤Gp0≤100% to avoid slight fluctuations in the final probability value. For example, when Gp0 is less than 80%, the judgment process is frequently triggered to ensure the judgment sensitivity while reducing misjudgment. Age constraints are set for the airway airbag safety dynamic compensation interval according to adults and children, so as to accurately match the airway airbag safety dynamic compensation interval according to target users of different ages, thereby improving the efficiency of pressure dynamic compensation.
[0135] Specifically, when the pressure dynamic compensation unit optimizes the airway bag safety dynamic compensation interval generation method based on the target emergency data, the heart rate change frequency Fx in the target emergency data is compared with the preset heart rate change frequency Fx0, and Fx=100 beats / minute is set. The heart rate change frequency is judged based on the comparison result, and the adult clinical restraint Px1 and the child clinical restraint Px2 are interval optimized based on the judgment result, wherein:
[0136] When Fx≥Fx0, the pressure dynamic compensation unit determines that the heart rate change frequency is normal, and does not perform interval optimization on the adult clinical restraint Px1 and the child clinical restraint Px2;
[0137] When Fx<Fx0, the pressure dynamic compensation unit determines that the heart rate change frequency is abnormal, and performs interval optimization on the adult clinical restraint Px1 and the child clinical restraint Px2. The interval optimization of the adult clinical restraint Px1 and the child clinical restraint Px2 is performed according to the variation coefficient ap, and ap=1.27-0.14×e -0.7×(Fx0-Fx) , where e is the base of the natural logarithm. The optimized adult clinical constraint Px1` and the optimized child clinical constraint Px2` are obtained. Px1`=Px1×ap is set. When Px1`>35cmH2O, Px1`=35cmH2O and Px2`=Px2×ap are set.

[0139] Specifically, the pressure dynamic compensation unit judges the situation of the heart rate change frequency. In this embodiment, Fx is set to 100 times / minute to avoid frequent optimization triggering when the heart rate change frequency fluctuates too little, such as when Fx is less than 100 times / minute, resulting in unstable interval optimization. At the same time, it avoids the situation where it is difficult to accurately capture the heart rate change frequency when the heart rate change frequency fluctuates greatly. When the heart rate change frequency is abnormal, the upper limit value of the airway airbag safety dynamic compensation interval is expanded by the change coefficient. The upper limit value of the airway airbag safety dynamic compensation interval is nonlinear with the change trend of the heart rate change frequency. In the early stage of the abnormal heart rate change frequency, the upper limit value of the airway airbag safety dynamic compensation interval needs to be quickly expanded to quickly optimize the interval. In the later stage, the abnormal rate of heart rate change frequency tends to be gentle. The change coefficient is set to match the change trend so as to reasonably increase the target user's breathing volume and avoid the airway airbag safety dynamic compensation interval affecting the target user's breathing when the heart rate decays, thereby improving the accuracy and efficiency of dynamic compensation.
[0140] Specifically, when the pressure dynamic compensation unit optimizes the airway bag safety dynamic compensation interval generation method according to the target emergency data, the blood flow abnormality value Pb is calculated according to the blood perfusion volume PUs and the baseline value PUb in the target emergency data, and Pb=(PUb-PUs) / PUb×100% is set to obtain the blood flow abnormality value Pb.

The situation of the blood flow abnormality is judged according to the comparison result, and the adult clinical restraint Px1 and the child clinical restraint Px2 are secondary interval optimized according to the judgment result, wherein:
[0141] When Pb≤Pb0, the pressure dynamic compensation unit determines that the abnormal blood flow value is not serious, and does not perform secondary interval optimization on the adult clinical constraint Px1 and the child clinical constraint Px2;
[0142] When Pb>Pb0, the pressure dynamic compensation unit determines that the blood flow abnormality is serious, and does not perform secondary interval optimization on the adult clinical constraint Px1 and the child clinical constraint Px2. Instead, the adult clinical constraint Px1 and the child clinical constraint Px2 are optimized secondary interval according to the contraction coefficient scx, and 0.4≤scx≤0.8 is set to obtain the secondary optimized adult clinical constraint Px1`` and the secondary optimized child clinical constraint Px2``. Px1``=Px1×scx is set. When Px1``<12cmH2O, Px1``=12cmH2O and Px2``=Px2×scx are set. When Px2``<12cmH2O, Px2``=12cmH2O are set.

[0144] Specifically, the pressure dynamic compensation unit judges the situation of the blood flow abnormality value. In this embodiment, Pb0≤15% is set to avoid the situation where the blood flow abnormality value fluctuates greatly and the serious situation of the blood flow abnormality value cannot be accurately captured, resulting in inaccurate optimization results. When the abnormal situation reflected by the blood flow abnormality value is serious, the lower limit of the airway airbag safety dynamic compensation interval is contracted according to the contraction coefficient. The lower limit of the airway airbag safety dynamic compensation interval is nonlinear with the change trend of the blood flow abnormality value. In the early stage of the serious blood flow abnormality value, the lower limit of the airway airbag safety dynamic compensation interval needs to be quickly reduced to quickly optimize. In the later stage, the change state of the blood flow abnormality value tends to be gentle, and the contraction coefficient is set to match the change trend, so as to reasonably avoid the inaccuracy of the airway airbag safety dynamic compensation interval caused by abnormal blood perfusion, thereby improving the efficiency of pressure dynamic compensation.
[0145] Specifically, when the pressure dynamic compensation unit optimizes the interval optimization process according to the pressure change acceleration, the pressure change acceleration Compare with the preset pressure change acceleration Vj0 and set Vj0=10Pa / h 2, judge the pressure change acceleration according to the comparison results, and optimize the contraction coefficient scx according to the judgment results, where:
[0146] when When ≤Vj0, the pressure dynamic compensation unit determines that the pressure change acceleration is normal and does not perform force optimization on the contraction coefficient scx;
[0147] when When Vj0 is higher, the pressure dynamic compensation unit determines that the pressure change acceleration is abnormal, and optimizes the contraction coefficient scx according to the force coefficient ld, setting ldy=1.57-0.23×e -0.38×(Vj-Vj0) , where e is the base of the natural logarithm, and the optimized shrinkage coefficient scx` is obtained. Set scx`=scx×ldy, replace the shrinkage coefficient scx with the optimized shrinkage coefficient scx`, and re-perform quadratic interval optimization on the adult clinical constraint Px1 and the child clinical constraint Px2 based on the optimized shrinkage coefficient scx`.
[0148] Specifically, the pressure dynamic compensation unit determines the acceleration of pressure change. In this embodiment, Vj0 is set to 10Pa / h. 2 , avoid frequent force optimization caused by small fluctuations in pressure change acceleration, thereby reducing misjudgment, and avoid large fluctuations in pressure change acceleration, which makes it difficult to accurately capture abnormal pressure change acceleration. When the pressure change acceleration is abnormal, the contraction coefficient scx is increased according to the force coefficient. The change trend of the contraction coefficient and the pressure change acceleration is nonlinear. In the early stage of the pressure change acceleration, the contraction coefficient needs to be quickly increased and the force optimization needs to be performed in time. In the later stage, the pressure change acceleration trend tends to be flat. The force coefficient is set to match the change trend, so as to reasonably avoid excessive pressure changes and insufficient contraction force in the airway bag safety dynamic compensation range when the blood flow abnormality is serious, thereby improving the efficiency of pressure dynamic compensation.
[0149] Specifically, when the control instruction generation unit obtains the pressure trend according to the ambient pressure prediction value and the airway airbag safety dynamic compensation interval, when the target user is an adult, the pressure change acceleration is calculated. The predicted ambient pressure value P is compared with the second preset pressure change acceleration Vj01 and the adult clinical restraint, which includes the lower limit value Pmin of the airway airbag safety dynamic compensation interval and the upper limit value Pmax1 of the adult airway airbag safety dynamic compensation interval. Vj01 is set to 0, Pmin = 12 cmH2O, and Pmax1 = 35 cmH2O. The high-altitude pressure risk is judged based on the comparison results, and the pressure trend is output based on the judgment results, where:
[0150] when >Vj01 and P>Pmax1, the control instruction generation unit determines that the high altitude pressure risk situation is risky and outputs the risk as a pressure trend;
[0151] when >Vj01 and Pmin<P≤Pmax1, the control instruction generation unit determines that the high-altitude pressure risk situation is no risk, does not control the airway bag pressure according to the airway bag pressure control method, and outputs no risk as the pressure trend;

[0155] when ≤Vj01 and P≤Pmin, the control instruction generating unit determines that the high-altitude pressure risk situation is no risk, does not control the airway bag pressure according to the airway bag pressure control method, and outputs no risk as the pressure trend;
[0156] When the target user is a child, the pressure change acceleration The predicted ambient pressure value P is compared with the second preset pressure change acceleration Vj01 and the child clinical restraint, which includes the lower limit value Pmin of the airway airbag safety dynamic compensation interval and the upper limit value Pmax2 of the child airway airbag safety dynamic compensation interval.
