The present invention relates to an integrated double cannula for an ECMO, and in a cannula inserted through a skin into a blood vessel during ECMO therapy, a blood inlet portion and a blood supply portion, which are separated by a partition wall, Wherein one end of the cannula body is opened to the end hole and the other end is opened side by side at an outlet port and an inlet port which are respectively connected to the blood inflow section and the blood supply section, And ECMO, because a plurality of side holes are formed. Therefore, even if a large amount of blood flows into the ECMO, it can be handled. And the number of side holes is increased, so that the blood flow amount is increased The blood recirculation phenomenon is remarkably reduced and the efficiency is improved. Since the partition wall is made of the synthetic resin material in the form of film, the shape is freely deformed and the blood flow amount is further increased by securing more space of the blood inflow portion or the blood supply portion It is effective.
