Assessment of the severity of behind blunt trauma in case of non penetration of body armor

Abstract

One of the main indicators of the quality of the body armor is analyzed - the level of the behind armor blunt impact when its protective structure is not penetrated. The main provisions of the current methodology for assessing the behind armor contusion injury used during medical and technical tests of body armor for military personnel of the Armed Forces of the Russian Federation are considered. In general, regression dependencies are presented that are used to predict the severity of damage caused by non-penetration of fabric-based body armor and body armor with rigid armor panels. The results of laboratory studies with different types of shock effects (under the same conditions) on biological soft tissue simulators (gelatin blocks) and biological objects – large experimental animals (pigs) weighing 60–80 kg are presented. It was established that when conducting tests using the currently accepted method, there is a statistically significant relationship between the predicted (based on the results of experiments on gelatin blocks) and the actual severity of damage according to the results of experiments on large animals. However, it was shown that the prediction of the severity of damage according to the existing dependencies intended for this purpose is somewhat overestimated and in most cases does not correspond to reality. Proved the need to continue research in this direction. The accumulation of experimental data on large experimental animals and the analysis of the clinical data of real victims who received an injury as a result of exposure of the injurious elements to a bulletproof vest will make it possible to refine the prognostic estimates of the tests of body armor and increase the effectiveness of their tests by the criterion of the level of impactor contusion.
