摘要
针对现有胸腔模拟器模拟逼真度不高等问题,研制一种新型机-气复合式胸腔模拟器。分别建立了主胸骨模拟器和肋骨模拟器数学模型,仿真分析模拟器的半径和高度、片弹簧厚度和宽度、腔内压力和压缩位移等因素对胸腔模拟器刚度特性的影响,并实验验证了模型的有效性。结果表明:通过改变模拟器腔内压力及模拟器的半径和高度、片弹簧厚度和宽度等结构参数可分别模拟不同年龄段和不同性别的患者的胸腔刚度。研究结果可为设计新型心肺复苏教学模拟装置提供参考。
In view of the low fidelity of existing thoracic simulator, a new type of machine-gas composite thoracic simulator was developed. The mathematical models of the main sternum simulator and the rib simulator were established respectively. The effects of the radius and height of the simulator, the thickness and width of the leaf spring, the pressure in the simulator cavity and the compression displacement on the stiffness characteristics of the thoracic simulator were simulated, and the validity of the model was verified by experiments. The results show that by changing the pressure in the cavity of the simulator and the structural parameters such as the radius and height of the simulator and the thickness and width of the plate spring, the thoracic stiffness of patients with different ages and genders can be simulated respectively. The research results can provide a reference for the design of a new type of cardiopulmonary resuscitation teaching simulation device.
