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。
Objective To explore the feasibility of underwater impact injury protection and some basic principles and methods to lay the foundation for the development of protective clothing for underwater impact injury. Methods Fifty rabbits were randomly divided into control group and protection group. Animals were respectively placed in pairs of decontamination centers of 500, 750, 100, 7500, 12500, 1500, Department, with 200 gTNT explosive ball underwater explosion, the use of pressure sensors to test underwater shock wave physical parameters. The animals were observed for survival and pathomorphology 6h after injury. Results The self-developed protective device has a significant protective effect against underwater impact injuries, especially in the lungs and gastrointestinal tract of the target organs, which are impacted by underwater impact. The total injury after the use of protective devices is reduced by 2 to 3 levels. Conclusion The protective device can greatly reduce the injury of the underwater impact injury.
