为研究机体及各组织器官对冲击力的耐受限值,探讨致伤原因及提出防护措施,利用着陆冲击塔,使实验动物恒河猴在坐姿状态下,进行冲击试验,试验后1h左右处死,作大体解剖观察并取心、肝、脾、肺、颞骨等组织,固定、切片、镜检。同时重点观察了内耳的损伤。结果表明,冲击载荷不大(平台过载值为≤25G)时内脏虽然有轻度损伤,但内耳可避免受损,当冲击力加大到一定程度(平台过载值为30~35G)导致内脏中等损伤时,内耳也有相应损伤,如囊斑耳石脱落、壶腹嵴上皮剥离等。
In order to study the tolerance limits of the body and tissues and organs to impact, explore the cause of injury and propose protective measures, use the landing impact tower to make the experimental animal rhesus monkey in sitting posture, and carry out the impact test and kill about 1 hour after the test , For general anatomy and coring, liver, spleen, lung, temporal bone and other tissues, fixed, section, microscopic examination. At the same time focus on the inner ear damage. The results showed that although the viscera is mildly damaged when the impact load is not large (the platform overload value is ≤25G), the inner ear can be prevented from being damaged. When the impact force is increased to a certain extent (the platform overload value is 30-35G), the visceral medium Damage, the inner ear also has the corresponding damage, such as plaque otolith loss, ampulla ridges epithelial stripping and so on.
