The invention relates to the technical field of
medical equipment, and provides an
extracorporeal circulation cannula which comprises a cannula body. A first opening area is arranged at the position, away from the first end by a first distance, of the side wall of the cannula body, and a plurality of first side holes are formed in the first opening area. The first side holes are arranged in the side wall of the cannula body in an array mode. According to the
intubation tube for
extracorporeal circulation, the first end of the
intubation tube body is inserted into the
venous blood vessel and communicated with the
venous blood vessel, and the second end of the
intubation tube body is communicated with the external equipment, so that the intubation tube is matched with the external equipment and the arterial intubation tube to form a circulation loop, and blood is drained out of the body from the body; after being subjected to
gas exchange by the membrane type
oxygenator, the gas is transfused back into the body through the
arterial cannula to temporarily replace the
cardiopulmonary function, so that
rescue treatment is provided for critical patients; meanwhile, the first side holes which are arranged in an array mode are formed in the position, close to the first end, of the cannula body, the first side holes can effectively improve the flow field near an outlet of the cannula, and the recirculation rate can be reduced easily.
