A medical catheter for satisfying different requirements of blood flow, oxygen concentration and blood pressure needed by various body parts during fetal extracorporeal circulation. The medical catheter comprises a main part (20). The main part (20) is internally provided with at least two first flow paths (40). Each of the first flow paths (40) is disposed independently from each other. Exits (A, B) of each of the first flow paths (40) are located at different locations along the length of the main part (20). The medical catheter is infused, through an inlet of the first flow path (40), with a fluid. The fluid then flows out through the exits (A, B) of the first flow path (40). Each of the first flow paths (40) outputs the fluid independently to satisfy different perfusion requirements of blood flow, oxygen concentration and blood pressure needed by various fetal body parts.
