Zusammenfassung:	The utility model discloses a blood perfusion device pressing cover. A blood nozzle (2) extends outward from the center of a pressing cover body (1); a ring-shaped groove (3) is arranged at the end surface of an opening end of the pressing cover body (1); the inner wall of the outer circumference of the ring-shaped groove (3) is of a step shape; and bars (5) are axially and uniformly distributed at the inner wall of the inner circumference of the ring-shaped groove (3). The blood perfusion device pressing cover has simple structure which is more suitable for ultrasonic welding, so that the pressing cover and a middle cylinder are fused into an integral structure, very good sealing property is still achieved after high-temperature and high-pressure sterilization, and the inside of a perfusion device is not easy to pollute.
