RESUMEN
Using engineering fluid dynamics (EFD) softwares,we conducted a study on the simulation of flow field in vessel which was partially blocked by a clamp. The flow field of the partial block vessel was studied once more in real vessel when methylene blue as a marker was injected into the vessel. The change in the characteristics of blood flow was observed by way of computer imitation and methylene blue show. It was found that some defect might appear in the conventional method which partially blocked the vein.

A new-designed axial flow blood pump, dived by magnetic coupling and using internal hollow brushless DC motor and inlet and outlet in line with impeller, was tested in mimic circuit. The results showed good performance of the new pump and indicated that its hydrodynamic characteristic can meet the demands of clinical extracorporeal circulation and auxiliary circulation.
