The invention relates to the technical field of nebulization
drug delivery devices, and discloses a nebulization
drug delivery device for newborns, which comprises an outer cylinder, a
drug loading cylinder and an atomization
mask, the top end of the drug loading cylinder is in threaded connection with a cylinder cover, the drug loading cylinder is inserted into the outer cylinder, and a through hole is formed in the bottom of the outer cylinder in a penetrating manner; a mist outlet connector is fixedly installed on the outer surface of the
medicine containing cylinder in a penetrating mode, a hose communicated with the mist outlet connector and the atomization
mask is detachably installed between the mist outlet connector and the atomization
mask, a
kidney-shaped groove is formed in the outer surface of the outer cylinder in a penetrating mode, the mist outlet connector penetrates through the
kidney-shaped groove, and an
oxygen inlet connector communicated with the interior of the
medicine containing cylinder is installed at the bottom of the
medicine containing cylinder. After liquid medicine in the medicine containing cylinder is used up, the two sealing blocks moving relatively can
cut off communication between the connecting
pipe and the
oxygen inlet connector, external
oxygen is prevented from being continuously transmitted into the atomization mask, and it is avoided that a newborn inhales high-concentration oxygen for a long time, stimulation is caused to the
respiratory tract, and cough or other
breathing discomfort is caused.
