浅析静脉瓣仿生技术在输液装置上的应用

Application of Bionic Technique of Venous Valve in Infusion Device

静脉输液是现今最常用的医疗治疗手段,保障输液疗效和安全是一项重要任务。简要概括国内外静脉输液现状以及存在的安全隐患,分别从人体内静脉瓣生理作用、静脉瓣式输液管仿生设计两方面分析,总结并展望静脉瓣式输液管仿生设计在静脉输液领域的应用前景。结果显示,依托仿生静脉瓣阻流原理设计一种成本低廉且能有效防止血液逆流的一次性输液装置。

Intravenous infusion is the most commonly used means of medical treatment.It is an important task to ensure the efficacy and safety of infusion.This paper briefly summarizes the current situation and potential safety hazards of intravenous infusion at home and abroad,analyzes the physiological function of human internal venous valve and the bionic design of venous valve infusion tube,and summarizes and prospects the application prospect of bionic design of venous valve infusion tube in the field of intravenous infusion.Finally,according to the analysis results,a low-cost disposable infusion device which can effectively prevent blood reflux is designed based on the flow blocking principle of bionic venous valve.
