The design of medical micro atomization device based on piezoelectric actuators

Abstract

In this paper, there is much demand for more advanced inhaled drug treatment on respiratory diseases treatment, so we design and manufacture a kind of medical micro atomization device based on piezoelectric actuators. In the experiment, the first measuring method we used is the diameter of the fog particles compare with quartz round bead in 1 micron. The second measuring method is weighing bibulous desiccant. The experimental results show that the fog particles produced by micro atomization device is 3 ∼ 4 microns in diameter, and fog particles rate is 0.07 ∼ 0.08 g/min. These data basically meets medical micro atomization device design requirements for the diameter and flow rate of fog particles on respiratory diseases treatment.
