Ventricular　assist　miniscule　pump　is　used　widely　to　support　heart　function　and　blood　flow　in　people　who　have　weakened　hearts.　However,　the　rotating　continuously　artificial　heart　pump　running　at　high　rotating　speed　would　damage　the　blood　cells　and　cause　hemolysis.　To　solve　this　problem,　a　novel　ventricular　assist　miniscule　nutation　pump　based　on　nutation　principle　was　proposed　in　this　paper.　The　researches　on　working　principle,　structure　design,　manufacturing,　assembling　and　experiment　are　proceeded　for　the　proposed　pump.　The　experimental　results　under　same　rotating　speed　and　different　output　pressure　were　obtained　and　discussed.　This　novel　nutation　pump　had　successfully　reduced　the　speed　of　rotating　parts　under　the　premise　of　necessary　flow　rate　without　increasing　the　pump　volume　and　weakened　the　damage　to　blood　cells.
