我们报告了一种新型分娩模拟器的设计、测试和实现，该模拟器是专门为研究分娩过程并改进临床培训而开发的，用于罕见但不可避免的复杂人类分娩。该模拟器由母体模型和仪表式胎儿模型组成，与现有的力传感系统和数据采集系统一起使用。母体模型包括骨骼、可旋转的骨盆、灵活的腿和子宫排泄系统。胎儿模型可以通过母体模型重复分娩，它使用电位器测量分娩过程中的颈部伸展、旋转和屈曲。在模型胎儿颈部内模拟臂丛神经，可以测量在困难分娩期间有受伤风险的神经的伸展。木质元素模仿新生儿骨骼的特性，可以自发或故意断裂。两种在模拟分娩过程中测量临床医生施加的力的方法为受训者提供了对其自身牵引力的实时评估，并允许研究人员将胎儿颈部运动和神经拉伸参数与临床医生施加的牵引力相关联。初步测试表明，该系统在分娩过程的最后阶段是生物逼真的，可以用于产科的培训和研究。
We report on the design, testing and implementation of a novel birthing simulator developed specifically to research the delivery process and improve clinical training in uncommon but inevitable complicated human births. The simulator consists of a maternal model and an instrumented fetal model, used in conjunction with an existing force-sensing system and a data-acquisition system. The maternal model includes a bony, rotatable pelvis, flexible legs, and a uterine expulsive system. The fetal model, which can be delivered repeatedly through the maternal model, is instrumented with potentiometers to measure neck extension, rotation and flexion during delivery. Simulation of the brachial plexus within the model fetal neck allows measurement of stretch in those nerves at risk for injury during difficult deliveries. Wooden elements mimic the properties of neonatal bone and can break either spontaneously or purposely. Two methods for measuring clinician-applied force during simulated deliveries provide trainees with real-time assessment of their own traction force and allow researchers to correlate fetal neck motion and nerve stretch parameters with clinician-applied traction. Preliminary testing indicates the system is biofidelic for the final stages of the birthing process, and can be used for training and research in obstetrics.
