常温环境下38mm软体变形弹生物致伤效应实验研究

目的:从生物学角度评估38mm软体变形弹的杀伤威力,并阐明其生物致伤效应。方法:常温条件下,对生物模型进行实弹射击,将猪和羊(各9只)按照射击距离的不同(3 m、5 m、10 m)分成三组,每组三只,射击部位为四肢、胸部、腹部及臀部。结果:局部损伤主要表现为单纯血液循环障碍或血液循环障碍伴随表皮剥落;临床解剖发现,在5 m距离上可致羊脏器破裂、肋骨骨折,在3 m距离上可致猪肺广泛性出血,同等条件羊的损伤程度较猪重。结论:我们认为,5 m距离内被38 mm软体变形弹击中,对人有可能造成血气胸,5 m距离外局部创伤可在数天后自行吸收、消退或愈合,一般无需医学处理。

Study on Biotraumatosenic Effect of 38 mmSoft-DeformedBullets Under Constant Temperature

Objective:In order to appraise lethality of 38 mm soft-deformed bullets in the biological perspective, and explain thebiotraumatosenic effect.Methods:Pigs and sheep were shot under constant temperature, the nine pigs and sheep were divided into 3groups according to distance of 3 m, 5 m and 10 m, each group contained three pigs or sheep, the shooting location were limb, chest,abdomen and buttock.Results:Clinical anatomy shows performance for local damage of animals was disturbance of blood circulation, ordisturbance of blood circulation in according with epidermal detachment; shoot in the distance of 5 m, viscera of sheep was broken, andrib fracture; in the distance of 3 m, the lung of pig was extensive blooding. Compared with pig, ability of sheep to fight off 38mmsoft-deformed bullets was weaker.Conclusion:we consider that shot by 38 mm soft-deformed bullets within 5m for person, thepneumohemothorax may occur, and the injured position could be self-absorbing, extinction or healing, generally medical treatment wasunnecessary.
