Apply to hospital operation room sucking mucus such as pus, blood, phlegm, in coelem of patient, also apply to induced abortion

※ Use efficient plunger pump which need no oil to lubricate, do not pollute, and have long life.

※ Suction pump is negative pressure, one-way pump, never produce positive pressure, ensure safety

※ Have negative pressure adjustive valve and check valve, be capable of adjusting safe pressure, and selecting arbitrary valure in safe pressure range

※ Pedal switch is controlled by low voltage, safe and convenient

※ Limit negative pressure value: ≥0.09Mpa under standard atmospheric pressure

※ Air suction rate: ≥20L/min(at the end), ≥30L/min(at the pump) under standard atmospheric pressure
