Description

Chemical emergency drilling wound simulation and first-aid training system and method Technical Field The invention belongs to the technical field of chemical engineering safety, and particularly relates to a chemical engineering emergency exercise wound simulation and first-aid training system and method. Background In the chemical industry field, as the production process involves numerous inflammable, explosive, toxic and harmful chemicals, once accidents occur, personnel are extremely easy to suffer various serious wounds, such as chemical burns, poisoning, mechanical wounds and the like, traditional first-aid training is often limited to theoretical explanation and simple manned model practical operation, and the existing wound simulation and first-aid training technology also has obvious defects: firstly, the general wound simulation system cannot adapt to special chemical injuries, namely, although the wound training system disclosed in U.S. patent No. 9342996B2 can simulate bleeding, the general wound simulation system is not designed aiming at special injuries such as chemical burns, chemical poisoning and the like, and cannot simulate abnormal physiological parameters caused by body fluid exudation, electrolyte disorder or poison. Secondly, virtual reality training and physical simulators lack effective integration, namely, three-dimensional emergency exercise systems are proposed by Chinese patents CN105976670A and CN101075275A, but the virtual scene construction and multi-role cooperation are focused, the virtual reality training and physical simulators are not organically combined with high-simulation physical simulators, and a learner cannot obtain immersive virtual experience and real touch feeling of physical operation at the same time. In addition, a dynamic feedback and intelligent assessment mechanism is lacking, for example, chinese patent CN120260369A discloses an artificial intelligence-based simulated live wire treatment training method, and the injury mapping and assessment are realized through mixed reality and motion capture, but the artificial intelligent live wire treatment training method is applied to battlefield environments, and is not related to special injury characteristics (such as chemical burns and poisoning) of chemical accidents, and an injury model depends on preset conditions, so that the injury evolution cannot be adjusted in real time according to the operation of students. In summary, the prior art cannot meet the requirements of high-simulation injury simulation, virtual-real integration, real-time feedback and intelligent evaluation in the emergency training of chemical accidents, so that the training effect is limited, and the participants are unskilled in emergency operation in actual rescue.
