基于浮球控制的多软袋输液的自动换液装置研究
A research about automatically replacing liquid device in a control of floating ball and in the application of infusion by using multi-soft bag
摘要
Abstract
Objective:To design a device which could automatically replace liquid and was suitable for infusion by using soft bag based on experience of the control for automatically replacing bottle device of multi hard bottle by floating ball valve.Methods: Through researched the core principle, control point and technical difficulties of the control theory of floating ball valve, and proposed solving ideas for suiting infusion of soft bag so as to achieve design and typification for the product. And then the product was verified and relative detail was improved through modeling research.Results: The results of verification showed that floating ball valve could realize infusion waiting and prevent regurgitation of liquid, and resolve the problem of automatically and successively replacing liquid in the transfusion by using soft bag.Conclusion: The design of floating ball valve in the application of automatically replacing bag in infusion of soft bag has a series of advantages including simple structure, lower cost, safe and reliability. And it can suit the basic situation that soft bag has been used in most of transfusion in clinical practice, therefore, it has well prospects in market.关键词
