Mock test characteristic of intraaortic balloon pump using linear motor

This article describes the composition of the intraaortic balloon pump (IABP) system, which uses a linear pulse motor, that is, the linear type of IABP, and the results of the mock test that was performed. The expansion time is 100-110 ms, and the contraction time is 85-95 ms at the balloon of the linear type IABP. This level is similar to that of the IABP system used in the market. When the speed of the mover is 0.3 m/s, the necessary thrust of the linear pulse motor to drive the balloon of the IABP is 200 N. The conversion efficiency from the bellows to the balloon is 5.6%, and the efficiency of the entire linear type IABP system is 0.6%. The volume of the entire system is 45 L, and the mass is 40 kg excluding the chassis. Therefore, there is an expectation that the IABP system can be miniaturized to about half of the conventional model.
