For　a　blood　pump,　high　shear　stress　and　bearing　wear　produced　by　its　high　rotational　speed　are　the　major　factors　causing　mechanical　damage　to　blood　cells　inside　the　pump.　To　eliminate　frictional　damage　to　blood　cells,　a　novel　magnetic　levitation　(maglev)　nutation　blood　pump　with　low　speed　and　small　volume　flow　is　developed　in　this　study.　The　flow-field　characteristics　and　hemolysis　performance　of　the　newly　designed　blood　pump　are　analyzed　and　the　feasibility　of　its　design　is　demonstrated.　We　use　computational　fluid　dynamics　and　the　dynamic　grid　method　to　solve　the　unsteady　3D　Navier-Stokes　equation　in　conjunction　with　the　standard　k-epsilon　model　to　simulate　and　analyze　the　internal　flow　field　of　the　blood　pump.　In　an　in　vitro　experiment,　an　in　vitro　circulation　loop　system　including　four　monitoring　sensors　is　established　and　fresh　sheep　blood　is　used　as　the　circulating　medium.　The　flow　pressure　is　tested　by　adjusting　the　speed　and　load　of　the　pump.　To　calculate　the　normalized　index　of　hemolysis　(NIH)　of　sheep　blood,　its　plasma-free　hemoglobin　and　hcmatocrit　levels　arc　detected　simultaneously.　The　prediction　results　of　velocity,　pressure,　and　shear　stress　distributions　in　the　3D　flow　field　of　the　pump　demonstrate　that　our　newly　designed　pump　has　an　antithrombotic　property　and　will　not　cause　serious　blood　damage.　The　in　vitro　experiment　suggests　that　a　continuous　output　of　more　than　5　L/min　can　be　obtained　at　a　100　mmHg　pressure　load　and　that　the　output　flow　of　the　pump　is　stable　at　different　pressures.　The　NIH　of　the　nutation　pump　is　0.0039　+/-　0.0006　g/100　L.　The　research　results　reveal　that　our　newly　designed　maglev　nutation　blood　pump　has　good　hemolytic　performance　and　a　stable　hydraulic　property　that　can　meet　the　requirements　for　animal　experiments.
