2.  Operating Principle

Schematic diagram for operating principle:
A negative pressure is generated by the electric negative pressure pump in the portable sputum aspirator. The needed negative pressure is generated in the collection container and suction pipeline via the regulation by the negative pressure regulation device. The pressure difference between the suction part and pipeline drives the liquid/solid to flow into the reservoir. The anti-overflow device is installed in the reservoir to prevent the aspired liquid/solid from entering the negative pressure pump. The air filter is installed between the aspiration container and negative pressure pump to block impurities from entering the negative pressure pump.
