Compression atomizing pump is a device for treating respiratory diseases. Mainly for asthma, bronchitis and so on. Composition: Compression pump, catheter, atomizer bottle Principle: compressed air pump produces compressed air through the catheter to the atomization bottle, atomization bottle equipped with a special treatment of the disease of liquid drugs, high-pressure air flow through the atomizer bottle at high speed will liquid Drugs are atomized into very fine particles. Among them, the effective particles for asthma are under 5 microns, and the atomized particles of ordinary compression atomizing pump have the percentage below 5 microns above 50%.
