Intra-Aortic Ballon Pump Using Linear Pulse Motor.

Abstract

Intra-Aortic Balloon Pump (IABP) is an effective device for support of the circulation. However, the small size of the IABP is required in the related fields.This paper proposes new small-sized IABP which is driven a Linear Pulse Motor (LPM) instead of the air-driven as the driving source. In generally, the LPM has advantages of high thrust/input power and good controllability. The developed LPM for IABP drive has high thrust/input power of 19.9 newtons/watt, it is also has kinetic thrust of 270 newtons at the range of speed from 100 to 140mm/s. IABP using the LPM has extremely simple constitution. As the result of the mock testing, the IABP using a LPM can be obtained not only same performance with the ordinary air-driven IABP, but the mass of the IABP will be reduce of half-size of the ordinary one.
