The air driven blood pump for total and partial cardiac support has a defect in durability. To solve this problem, we present a new type of blood pump, driven by a linear motor. This pump consists of a straight conduit sandwiched between two stators, and of a metalic rotor.
The rotor is driven back and forth in the conduit by excitation of two stators. As the result of this movement, the fluid is sucked into and ejected from this conduit. The movement of this rotor is controlled so easily by changing source current and frequency that many output flow patterns can be generated.
The pump characteristics were examined, using overflow tank system.
Maximum output flow rate was over 3 [1/min] at mean load pressure 100 [mmHg]. Pump beat number was able to vary from 15 to 120 [bpm].
And it was shown that this pump can be operated in complete silence.
