摘要
目的研究人体胸廓力学特性,据此对现有模型进行适当简化,用于指导心肺复苏模拟人的研制。方法从人体解剖结构、材料物理性质等方面出发,提出Gruben模型的简化方法,采用现有人体实验数据进行分析和验证。通过对模型的检验及残差分析,以证明该模型的可行性。结果推导出的简化模型表达式比Gruben的模型减少了3项,人体试验数据验证该模型决定系数均接近1,残差较小,并给出了该模型的"典型人"参数。结论该模型从新的角度进行构建,为人体胸廓在按压下的力-位移关系的模型研究提供了一种新的方法;模型结构相对简单,易于采用物理结构实现,可为心肺复苏模拟人胸廓力学特性的改进提供指导。
Objective To create a model with simple expression of mechanical characteristics of the human chest for the development of a manikin.Methods A simplified Gruben-model was proposed based on the anatomical structure and physical characteristics of the materials,and perfect coefficients were computed.The model feasibility was proved by the coefficient of determination and residual analysis.Results The mathematic form of the model provided had three fewer terms than Gruben＇s.The coefficient of determination approximated 1,the residue was small,and the perfect coefficients of ＂a typical human＂ were determined.Conclusion The hypothesis of the model makes the coefficients physically meaningful,which provides a new method to study the force-displacement relationship of the thorax.Also the simple form makes it easy to create the model and provide some guidance for the design of a manikin＇s chest.
