Up till now, the main pump types used in CPB are roller pump and centrifugal pump, but these two kinds of pump both have their own disadvantages. When roller pump is used, the blood cells will be destroyed severely and when the pipeline is kinked, air will be transported into body or the conduit will be broken. The function of centrifugal pump is better than that of roller pump, but now, this kind of pumps are all designed for adults, and when the flow rate is low, the function of protecting the blood is not significant.

目前，滚轴泵和离心泵是心肺转流中的常用泵型，但是滚轴泵对血液有形成分的破坏较严重，而且有引起泵管的崩脱和大量气体泵入体内的危险性；离心泵虽然在性能上优于滚轴泵，但目前的离心泵大都是为成人设计的，而且在低流量时在血液破坏方面的优点不明显，此外它们还有一个共同的缺点就是预充量均大，因此两者都不适合在幼婴儿体外循环中应用。
