In Vitro Study on the Dynamics of Blood Flow Impelled by an Alternating Current Magnetohydrodynamic Blood Pump

This study demonstrated several findings: (i) Continuous sheep blood flow can be achieved; (ii) The blood cell counts remained unchanged after 3 h of exposure to an alternating magnetic field; (iii) Compared with the c ontrol group, the high‐ and low‐shear viscosities of the whole blood from the sheep significantly decreased after 3 h of exposure to an alternating magnetic field (P< 0.05 andP< 0.01, respectively). Plasma viscosity was significantly reduced after exposure to high ‐intensity alternating magnetic fields (P< 0.001); (iv) The cytoplasm of blood cells (especially erythrocytes) became lighter in color in the exposure group compared to the control group, and “beads‐on‐string” aggregations of black particles appeared. This work provides detailed and reliable scientific research data for the development of this type of blood pump, which may serve as a transition to the clinical artificial heart.
