摘　　要：目的研究并开发一种用物理原理控制的、不耗电的医用输液自动换瓶装置来减轻临床护士换瓶工作量。方法先对比分析各物理原理控制的自动换瓶装置的优缺点,找出浮球阀门控制的核心原理、控制位点及技术难点,对浮球及浮球阀门室的相关指标进行函数推导,根据推导结果确定适合的参数,包括医用材料选择、浮球阀门形状及大小、阀门室大小及各开口位置等并最终设计成型。结果通过建模验证浮球阀门实现了控制液体、气体分时相、分通道通过输液头的功能。结论该浮球阀门控制的自动换瓶装置结构简单,成本低廉,使用便捷,安全可靠,且为全软袋输液或软袋硬瓶混合输液的自动换瓶装置研究提供了一个全新的解决思路。Objective To develop a medical infusion automatic bottle change device that was physical principle controlled and was without power consumption so as to alleviate the workload of clinical nurses. Methods Firstly, the advantages and disadvantages of each automatic bottle change device guided by physical principle were analyzed. Then, the core principles of float valve control, locus control and technical difficulties were found out. The function of relevant indicators of floating ball and float valve chamber was deduced. Based on the derived results, suitable parameters including medical material selection, shape and size of float valve, size of the valve chamber and each open position were decided and final design was determined. Results Through modeling and verification float valve, functions like liquid control, gas phase time-sharing and channeled infusion were realized. Conclusion The structure of this automatic bottle change device controlled by float valve is simple. The cost of it is low. In addition, it is easy to use, as well as safe and reliable. It provides a new solution for automatic bottle change device of soft bag injection and the mixed infusion of soft bag and hard bottle.
