Trauma affect between 3 and 7% of all pregnancies in industrialized countries, and the leading cause of these traumas is car crashes. The difficulty to appreciate physiologic and anatomic changes occurring during pregnancy explain that majority of studies were not based on anatomical data. We present a protocol to create a realistic anatomical model of pregnant woman using a post mortem human subject (PMHS).
We inserted a physical model of the gravid uterus into the pelvis of a PMHS. 3D acceleration sensors were placed on the subject to measure the acceleration on different body segments. We simulated three frontal impact situations at 20 km/h between two average European cars.
Two main kinematics events were identified as possible causes of injuries: lap belt loading and backrest impact.
Cadaver experiments provide one interesting complementary approach to study injury mechanisms related to road accidents involving pregnant women. This anatomical accuracy makes it possible to progress in the field of safety devices.
在工业化国家，创伤影响3%至7%的所有妊娠，而这些创伤的主要原因是车祸。难以理解孕期发生的生理和解剖学变化，这说明大多数研究并非基于解剖学数据。我们提出了一个使用尸体（PMHS）创建逼真的孕妇解剖模型的方案。
我们将妊娠子宫的物理模型插入一具尸体的骨盆中。在该尸体上放置三维加速度传感器，以测量不同身体部位的加速度。我们模拟了两辆普通欧洲汽车以20公里/小时的速度发生的三次正面碰撞情况。
确定了两个主要的运动学事件可能是受伤的原因：安全带加载和靠背碰撞。
尸体实验为研究涉及孕妇的道路交通事故相关损伤机制提供了一种有趣的补充方法。这种解剖学准确性使得在安全装置领域取得进展成为可能。
