The blood pump 1 is a centrifugal pump. In the utility model, the blood pump, the membrane lung, the variable-temperature water tank and the air-oxygen mixer are all of the existing structures and can be directly purchased, and the blood pump is a centrifugal pump.

When the device works, blood firstly enters the blood introducing tube 5, the blood is unoxygenated blood, the blood pump 1 conveys the unoxygenated blood to the membrane lung 2, and the membrane lung 2 is connected with the air-oxygen mixer 4, so that the air-oxygen mixer 4 mixes oxygen and air according to a certain proportion and then inputs the mixed oxygen and air into the membrane lung 2, and oxygen is injected into the unoxygenated blood to supply needed oxygen for a patient to maintain life; after passing through the membrane lung 2, the unoxidized blood becomes oxygenated blood, which is then introduced into the human body through the blood-feeding tube 7.
