A disposable urine bag having an accurate measurement function, comprising a bag body (1), a first fixed tube (2) and a second fixed tube (3) being respectively fixedly connected to an inner top wall and an inner side wall of the bag body (1), partition plates (4) being fixedly connected to a lower surface of the first fixing tube (2) and an upper surface of the second fixing tube (3), and five partition plates (4) being evenly distributed on the lower surface of the first fixed tube (2) and the upper surface of the second fixed tube (3). When the disposable urine bag is in use, the urine of a patient flows from a urinary catheter (12) through a liquid intake tube (10) and a hose (14) into a first liquid storage chamber (5)； when the liquid chamber (5) is fully filled with urine, the urine enters a second liquid storage chamber (6) by means of a shunt hole (15)； when the second liquid storage chamber (6) is fully filled with urine, the urine enters a third liquid storage chamber (7) by means of a shunt hole (15)； and when the third liquid storage chamber (7) is fully filled with urine, the urine enters a fourth liquid storage chamber (8) by means of a shunt hole (15)； medical personnel may accurately record the volume of urine according to urine levels in the first liquid storage chamber (5), the second liquid storage chamber (6), the third liquid storage chamber (7) and the fourth liquid storage chamber (8), thus the urine bag has the characteristic of accurately measuring the volume of urine.La présente invention concerne une poche à urine jetable ayant une fonction de mesure précise, comprenant un corps de poche (1), un premier tube fixe (2) et un second tube fixe (3) étant respectivement reliés de façon fixe à une paroi supérieure interne et à une paroi latérale interne du corps de poche (1), des plaques de séparation (4) étant reliées de manière fixe à une surface inférieure du premier tube de fixation (2) et à une surface supérieure du second tube de fixation
