The manual sputum suction device consists of a water pump, a piston, a handle, a sputum storage chamber, a sputum suction tube and a sputum discharge tube joint. It is mainly used to clear respiratory secretions and keep the respiratory tract open.
Working Principle: After pressing the handle, a negative pressure is formed in the sputum storage chamber and the patient's mouth/throat. The resulting pressure difference allows sputum to pass through the oropharynx into the storage chamber.
