1. A magnetic drive centrifugal pump comprising:
at least one internally hollow body provided with at least one inlet connector and with at least one outlet connector for blood;
at least one rotor element, housed inside said at least one internally hollow body and provided with at least one portion made of magnetic material, said at least one rotor element being magnetically commanded in rotation around an axis, without contact, by a stator element associable with said at least one internally hollow body; and
at least one support element of capable of supporting said at least one internally hollow body wherein said at least one support element is associable with said stator element;
wherein the magnetic drive centrifugal pump comprises removable locking means wherein said removable locking means is capable of locking said at least one internally hollow body to said at least one support element and wherein said removable locking means locks a movement of said at least one internally hollow body with respect to said at least one support element along at least one direction, where said removable locking means comprise:
at least one load-bearing element,
first locking means engageable in a removable manner with said at least one internally hollow body, wherein said first locking means locks said at least one internally hollow body to said at least one load-bearing element along said at least one direction with respect to said at least one load-bearing element, wherein said at least one internally hollow body being movable in rotation around said axis with respect to said at least one load-bearing element when the first looking means is engaged with said at least one internally hollow body, and
second locking means engageable in a removable manner with said at least one support element, said removable locking means being movable between at least one release configuration, wherein said second locking means are disengaged from said at least one support element and said at least one load-bearing element is movable along said at least one direction in travel-with respect to said at least one support element, and at least one locking configuration, wherein said second locking means engage with said at least one support element to secure said at least one load-bearing element along said at least one direction with respect thereto, said at least one internally hollow body being movable in rotation around said axis with respect to said at least one support element with said removable locking means in the locking configuration.
