Abstract:
This paper designs a new distributing structure of nozzles in medical micro-jet device on the bases of emulating results. This new structure can improve the output coefficient and flux of drug delivery. Then, a micro-jet device is fabricated by MEMS technology based on this structure. The experiment results indicate that the number of output droplet is approximated to normal distribution on droplet diameter and velocity. Moreover, the droplet velocity and the flux are both improved in this new micro-jet device, whose values are 2.93m/s and 11.77?l/s respectively.
