间歇式雾化控制器的研制

Development of the Controller for Alternative Nebulizer

目的研制一种用于控制超声雾化器和喷射雾化器间歇喷雾的控制器,改善雾化工作方式,达到节约雾化用药和减少雾化环境影响的目的。方法采用单片机设计控制器,可以调节间歇频率和占空比;通过继电器控制超声雾化器,通过电磁阀控制喷射式雾化器,实现两种形式的间歇雾化。结果可以实现与病人呼吸基本同步的间歇雾化控制。结论试验证明,该控制器调节方便,可以节约雾化用药50%左右,同时减少排放环境的雾化药物量50%左右。

Objective To develop a nebulizer controller which can be used to control the ultrasonic nebulizer and spray atomizer. which can optimize the working of the nebulizer in pulse way, in a purpose to save the medication and minimize the impact on the environment. Methods Design the controller by using SCM to adjust the frequency and dutyfactor of the nebulizer pulse. The output pulse of the controller can drive a relay or a electromagnetic valve to control the pulse work of the two kind of nebulizer. Results The controller can work in a pulse way, and patients can inhale in pace with the nebulzer. Conclusion The controller can save the medication by 50%, and reduce the impact on the environment by 50%.
