【摘要】：目的　探讨水下冲击伤防护的可行性和一些基本原理和方法 ,为研制水下冲击伤的防护服奠定基础。方法　 5 0只兔 ,随机分为对照组和防护组 ,分别将动物成对置于离爆心 5 0 0、7 5 0、8 75、10 0 0、12 5 0、15 0 0、17 5 0m处 ,用 2 0 0 gTNT炸药球进行水下爆炸 ,采用压力传感器测试水下冲击波的物理参数。观察伤后 6h动物的存活情况和病理形态学改变。结果　自行研制的防护装置对水下冲击伤具有明显的防护作用 ,尤以对水下冲击伤的靶器官肺和胃肠道最为明显 ,使用防护装置后其总伤情降低了 2～ 3级。结论　防护装置可大大减轻水下冲击伤的伤情。
[Abstract]:Objective to explore the feasibility and some basic principles and methods of underwater blast injury protection, so as to lay a foundation for the development of underwater blast injury protective clothing. Methods Fifty rabbits were randomly divided into two groups: the control group and the protective group. The animals were placed in pairs at a distance of 8 750 m from the center of detonation. The animals were subjected to underwater explosion with 2 000 gTNT explosive ball. The physical parameters of underwater shock wave were measured by pressure sensor. The survival and pathomorphological changes were observed 6 hours after injury. Results the self-made protective device had obvious protective effect on underwater blast injury, especially on the target organ lung and gastrointestinal tract of underwater blast injury. The total injury condition was reduced by 2 ~ 3 grade after the use of the protective device. Conclusion the protective device can greatly reduce the injury of underwater blast injury.
