When the opening and closing components inside one shunt tube 4 are in the open state, the opening and closing components inside the other three shunt tubes 4 are in the closed state. At this time, urine can only be discharged through the opened shunt tubes 4 and discharged into the corresponding sampling urine storage bag 1, thereby realizing time-divided storage and sampling. On the one hand, it prevents urine from multiple time periods from being mixed together in large quantities, resulting in poor sampling results and affecting the subsequent urine detection results. On the other hand, it is convenient for medical staff to observe the patient's urine output and urine conditions in different time periods.
