WATER DIVIDER FOR PREVENT REFLUX OF CONDENSATE WATER IN A VENTILATOR, AND RESPIRATORY CIRCUIT AND VENTILATOR USING THE SAME

Abstract: a water divider provided includes a tube body, and a gas splitting assembly. the water divider provides with a branch water tube, and a user tube opening, a drainage outlets, and an internal opening arranged in sequence along the branch water tube. the branch water tube is located between two ends of the main airway and communicated to the main airway. gas exhaled by a user forms an airflow that flows from one end of the main airway into the branch water tube through the user tube opening, and flows out of the branch water tube from the internal opening into the other end of the main airway. the drainage outlet is connected an external liquid collection device. the gas splitting assembly locates in the branch water tube, and enables the airflow rotating when the airflow flows into the gas splitting assembly.
