a3, after drainage treatment, a doctor takes out a drainage tube (17) from a patient body, then takes out a sealing plug (24) from a pressure regulating tube to balance the air pressure in a drainage bottle (1), at the moment, the doctor opens a valve (5) to discharge accumulated liquid in the drainage bottle (1) through a liquid discharge tube (4), when the device needs to be cleaned, the doctor rotates two screws (14) in sequence to separate the screws (14) from a connecting ring (15), then moves the regulating tube (16) to separate the regulating tube (16) from the liquid inlet tube (22), at the moment, the doctor injects flushing liquid into the drainage bottle (1) through the liquid inlet tube (22) to clean and disinfect, and after disinfection, the doctor utilizes the two screws (14) and the connecting ring (15) to connect the regulating tube (16) and the liquid inlet tube (22).
