How to use the drainage device connected to the thoracentesis needle drainage?

①Collection bottle: used to collect pleural effusion

②Water-sealed bottle: about 3cm is below the water surface of the water-sealed bottle (usually 1-3cm can be placed, too deep is not conducive to exhaust). The hydrostatic pressure generated by the liquid column in the water-sealed bottle will oppose the negative pressure of the pleural cavity, prevent the water in the bottle from sucking back and ensure that the gas does not flow back into the chest cavity.

③ Manometer bottle: There is a vent tube under the liquid surface in the manometer bottle, which can adjust the negative pressure generated by the aspirator. The negative pressure generated by turning on the suction device is equal to the depth of the water-sealed adjustable vent tube.
