摘要： In a method for the determination of the viscosity (&eegr;) of a liquid, e.g. of blood, which is forwarded by a pump, e.g. a blood pump, said pump having a rotor for the forwarding of the liquid from the inlet of the pump to the outlet, the rotor is used for the determination of the viscosity (&eegr;). For the determination of the viscosity (&eegr;) of the liquid no spatial deflection of the rotor from its operating position takes place, but rather the rotor is left in its operating position and the viscosity (&eegr;) is determined from measurement parameters of the pump or of the rotor respectively.

摘要： Disclosed is a rotary pump including a magnetic rotor arranged in a pump housing and having a magnetic rotor plane, which rotor is operatively connected to a drive for conveying a fluid. The drive is a bearingless motor having a stator configured as a bearing stator and drive stator and having a magnetic stator plane, wherein the stator bears a drive coil and a bearing coil lying in the stator plane and/or a drive bearing coil. The rotor is magnetically contactlessly journalled within the stator, wherein an axial height (H) of the rotor is smaller than or equal to half a diameter (D) of the rotor so that the rotor is passively magnetically stabilized by reluctance forces with respect to the magnetic stator plane both against axial displacement and against a tilt from an equilibrium position.

The method includes providing at least one substance consisting of one of a tissue part, a scaffold having cells deposited thereon, and a scaffold including a tissue part thereon. The method further includes further acting upon the substance with fluid, wherein the fluid holds the substance in free floatation. The fluid flows in a direction counter to gravity when a density of the substance is greater than a density of the fluid, and in a direction counter to buoyancy when a density of the substance is less than a density of the fluid. The bioreactor for floating at least one substance for growing a tissue part includes a container including a first flow chamber and at least one substance consisting of one of a tissue part, a scaffold having cells deposited thereon, and a scaffold including a tissue part thereon. The substance is acted upon with fluid. The bioreactor further includes an apparatus for conveying the fluid.
