摘　　要：为解决目前临床使用的雾化器因缺乏反馈控制功能,存在使用场景局限且易造成药物污染和浪费的问题,本研究设计了一种基于浓度阈值的自适应雾化器控制系统。通过加装浓度传感器,并基于Arduino平台编写控制程序,实现根据药物使用量控制雾化器产生符合需求的气溶胶浓度,并利用单向阀确保气流单向流动。结果显示,与传统雾化器相比,本研究设计的雾化器药物消耗量约减少75%,药物残留少。该装置能够减少药物浪费、节约雾化用药、改善雾化治疗环境。In order to solve the problems that the nebulizer used in clinic is limited in use scenario,causing drug pollution and waste due to lack of feedback control function,we designed an adaptive atomizer control system based on concentration threshold.By adding a concentration sensor,a control program based on the Arduino platform was wrote to control the atomizer to produce an aerosol concentration that met the requirements the amounts of drug used,and a one-way valve was used to ensure one-way air flow.The results showed that compared with the traditional atomizer,the drug consumption of this atomizer was reduced by about 75%,and the drug residue was less.The device can reduce drug waste,save atomized medication,and improve the atomized treatment environment.
