一种浮球控制通用型医用输液自动换瓶装置的研究

Research on an Automatic Bottling Device for Medical Infusion Controlled by Floating Ball

目的设计一种能同时适用于串联多个软袋或硬瓶输液且应用浮球阀门控制的自动换瓶装置。方法整合用于硬瓶的和软袋的自动换瓶原理,即整合硬瓶的自动控制适时进气、适时出液原理和软袋的自动控制适时终止输注等待的原理。并能实现在两个融合原理中自动选择、自由切换其控制原理。结果通过建模模拟并实验运行,结果显示当前输液头能在前一瓶输注完毕后及时开闭各通道,实现自动换瓶。结论浮球控制通用型自动换瓶输液头控制原理新颖,产品设计合理、结构巧妙、成本低廉且使用方便。

Objective To design an automatic bottle changing device which can be used for serial infusion of multiple soft bags or hard bottles at the same time and controlled by floating ball valve.Methods By integrating the principle of automatic bottle changing for hard bottles and soft bags,integrating the principle of automatic control of timely air intake and timely liquid output of hard bottles and the principle of automatic control of soft bag to stop infusion waiting.And the control principle can be automatically selected and freely switched between the two fusion principles.Results Through modeling simulation and experimental operation,the results show that the current infusion head can open and close each channel in time after the completion of the infusion of the previous bottle,so as to realize automatic bottling.Conclusion Float control universal automatic bottle changing infusion head has novel control principle,reasonable product design structure,ingenious principle structure,low cost and convenient use.
