This study explored the variation of bursting force of multi-chamber infusion bag with different geometry size, providing guidance for its optimal design. Models of single-chamber infusion bag with different size were established. The finite element based on fluid cavity method was adopted to calculate the fluid-solid coupling deformation process of infusion bag to obtain corresponding critical bursting force. As a result, we proposed an empirical formula predicting the critical bursting force of one chamber infusion bag with specified geometry size. Besides, a theoretical analysis, which determines the force condition of three chamber infusion bag when falling from high altitude, was conducted. The proportion of force loaded on different chamber was gained. The results indicated that critical bursting force is positively related to the length and width of the chamber, and negatively related to the height of the chamber. While the infusion bag falling, the impact force loaded on each chamber is proportional to the total liquid within it. To raise the critical bursting force of in fusion bag, a greater length and width corresponding to reduced height are recommended considering the volume of liquid needed to be filled in.为研究多室输液袋弱焊条压裂力随腔室几何尺寸的变化规律，指导多室输液袋的优化设计，本文建立了不同尺寸的单腔室输液袋模型，采用基于流体腔的数值计算方法对输液袋进行流固耦合分析，获得临界压裂力随腔室几何尺寸的变化规律，提出单腔室输液袋的临界压裂力经验公式；对多室输液袋跌落时的受力情况进行理论分析，确定各腔室的受力比。结果表明，临界压裂力与腔室的长度和宽度呈正相关，与腔室的高度呈负相关；输液袋跌落时各腔室所受冲击力与腔室所装的液体体积成正比。为提高输液袋的临界压裂力，应结合各腔室装液体积，尽量提高输液袋的长度和宽度，降低高度。. |
