The liquid discharge pump 423 is started, the liquid discharge pump 423 sucks the liquid in the waste liquid collecting container 1091 through the suction connector 212 and injects the sucked liquid into the waste liquid collecting container 1091 through the liquid feeding connector 214, and the control module 501 controls the first liquid adding pump 443 to quantitatively add the disinfectant into the input liquid path 4101 through the liquid adding pipeline 440 according to the waste liquid amount in the waste liquid collecting container 1091. Since the flushing port diameter of the flushing tip is typically small, to prevent clogging of the flushing port, after the disinfection program is initiated, the control module 501 opens the first bypass control valve 414 to communicate with the first input bypass 411 and closes the second bypass control valve 415 to block the second input bypass 412.
