The present invention discloses a portable active
inhalation drug delivery device based on MEMS, comprising: a liquid
medicine box, an oil guide plate, a porous oil guide member, an atomization
chip, a base, a PCB board and a suction
nozzle, a liquid
medicine guide port is provided at the bottom of the liquid
medicine box, a symmetrically arranged air intake through hole is provided on one opposite side wall of the liquid medicine box, an air intake groove is provided on the oil guide plate, two air intake through holes are symmetrically arranged at both ends of the air intake groove, the porous oil guide member is fixedly mounted on the back of the oil guide plate, the atomization
chip is fixedly mounted on the mounting seat of the base, the PCB board is fixedly mounted on the back of the base, a first
aerosol channel is provided in the mounting seat, a
metal electrode is provided on the mounting seat, the suction
nozzle is fixedly mounted on the base, and a second
aerosol channel is provided in the suction
nozzle. Compared with the prior art, the present invention has uniform atomization of liquid medicine, a high proportion of liquid medicine particles with a target
diameter, and active
inhalation drug delivery, which effectively controls the dosage and prevents
choking and coughing.
