Abstract :
The application of spray device to treat respiratory disease has been effective for a long time. Moreover, the clinical studies show that if the droplet size is finer, the deeper position of the trachea could be reached. With an eye on enhancing the curative effect, this paper proposed a novel nebulizer integrating the piezoelectric actuator, micro nozzle plate, and the cavity of micro pump to achieve high-quality atomizing effect. According to the simulations and the experiments, it can be inferred that the droplet size distribution of the nebulizer in this research is finer and more uniform than the conventional ones. Furthermore, the system power consumption is lower than the former ultrasonic type
