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 and throat. Under the pressure difference, the sputum passes through the oropharynx and is suctioned into the storage chamber.

• Suitable for suctioning blood and fluid accumulation during routine medical rescue.
• Adjustable suction power via the regulating valve for different scenarios.
• High-performance spring and connecting rod devices for fast and labor-saving operation.
• Equipped with a floating device to avoid over-absorption of liquid.
• Includes two specifications of suction tubes to meet different requirements.
