目的 探讨半预制破片杀爆弹致伤动物后的伤情特点。方法 采用西北健康山羊 32只 ,雌雄不拘。某型半预制破片杀爆弹 1发 ,立于地面约 1.6m高 ,电引信起爆。动物均为右侧面向爆心 ,呈扇形分布 ,距离分别为 10、10 (战壕 )、15、15 (战壕 )、2 0、2 5、30、4 0、5 0、6 5、80m ;相应距离的动物数分别是 3、3、3、2、3、3、3、3、3、3、3只。结果 32只实验动物中 ,经杀爆弹致伤后 ,有 2 1只动物即刻死亡 ,占动物总数的 6 5 .6 3% ;伤后 18小时内死亡 3只 ,占 6 .2 5 % ,活存 18小时动物 8只 ,占 2 5 .0 0 % ;全身毁损为 6只 ,占动物总数的18.75 %。其中两种距离战壕的动物存活率为 1/ 3和 2 / 2。破片伤、冲击伤、多发伤、多处伤和骨折的发生率分别为 6 8.75 %、37.5 %、6 5 .6 3%、6 .2 5 %和 4 3.75 %。其中盲管伤和贯通伤分别为 12 .2 0 %、87.80 %。结论 某型半预制破片杀爆弹由于破片和冲击波的复合作用造成动物伤型和伤情均较为复杂 ,在救治中必须给予特别的重视 ;同时 ,战壕对杀爆弹的破片和冲击波的损伤有一定的防护效果。
Objective To investigate the characteristics of the injury after the semi-prefabricated fragments were killed by the bomb. Methods 32 healthy goats in Northwest China were used, both male and female. A semi-prefabricated piece of explosive bomb 1 shot, standing on the ground about 1.6m high, electric fuses detonated. Animals are on the right side facing the heart of the explosion, was fan-shaped, the distance was 10,10 (trench), 15,15 (trench), 20,25,30,4 0,5 0,6 5,80 m; the corresponding distance The number of animals are 3,3,3,2,3,3,3,3,3,3,3,3. Results In 32 experimental animals, 21 animals died immediately after being killed by the bomb, accounting for 65.36% of the total number of animals; 3 died within 18 hours after injury, accounting for 6.25% Eight live animals survived for 18 hours, accounting for 25.0% of the total; 6 were systemic lesions, accounting for 18.75% of the total number of animals. Two of these animals survived from trenches at rates of 1/3 and 2/2. The incidence of fragmentation, impact injury, multiple injuries, multiple injuries and fractures were 6 8.75%, 37.5%, 65.33%, 6.25% and 4.75%, respectively. Blind wounds and penetrating wounds were 12.0% and 87.80% respectively. Conclusion A certain type of semi-prefabricated fragment projectile bomb explodes and the injury caused by the compound action of fragments and shock waves are complicated. Special care must be taken in the treatment. At the same time, the tornadoes damage the fragments and shock wave of the bomb A certain protective effect.
