A Novel Ventricular Assist Miniscule Maglev Nutation Pump: Structure Design,3D Modelling and Simulation
The ventricle assist device has emerged as an important therapeutic option in the treatment of both acute and chronic heart failure.The blood pumps,the major components of ventricle assist devices,have also progressed to the third generation.The magnetic levitation technologies have been applied into the third generation blood pumps.This paper proposes a novel miniscule maglev nutation pump with Magnetic bearing based on nutation principle.The calculation formula of magnetic force is established on the basis of the research for the operational principle of the magnetic bearing.Through establishing and solving the equations,the structural dimension and magnetization intensity of the magnetic bearing are obtained.Then,the three-dimensional model of the nutation pump is established.Furthermore,the structure design,manufacturing and assembling of the pump is completed.Finally,the simulation of the maglev nutation pump is carried out.And the effectiveness of the miniscule maglev nutation pump is verified.
