The application discloses a kind of tangential magnetization rotor integrated shaftless impeller's magnetic suspension artificial heart pump structure, including impeller and several equidistantly connected independent blades of equal size and material in rotor inside, the blade is located in rotor center, but not connected on main shaft, realize the integration of impeller and rotor and the shaftless of impeller, improve traditional central shaft driven impeller to four peripheral driving type.Blade equidistantly connects in rotor shield sleeve inside, realizes shaftless, to be integrated with rotor in one body.The application adopts above-mentioned tangential magnetization rotor integrated shaftless impeller's magnetic suspension artificial heart pump structure and can reduce motor volume, easy to transplant;Meanwhile, the integrated structure can prevent blood from flowing through motor air gap to the maximum, to reduce the situation of hemolysis and thrombosis.

The application relates to a microfluidic device, a support and a plasma separation method for whole blood filtration, comprising a body, a filtration mechanism arranged in the body and a collection tank in communication with the filtration mechanism, the filtration mechanism is used for filtering red blood cells, and the collection tank is used for collecting plasma; the application further comprises a driving mechanism used for driving a sample in the body to move from a side where the filtration mechanism is located to a side where the collection tank is located. The driving mechanism can improve the flow speed of the sample, thereby improving the whole blood filtration speed, shortening the whole blood separation time and reducing the possibility of hemolysis. The microfluidic device provided by the embodiment can obtain plasma without a centrifuge, has a small device volume and is easy to operate.
