Abstract
A newly designed vibrating flow pump (VFP) using cross-slider mechanism has been developed. The cross-slider mechanism converts rotary motion of electric motor to straight-line motion of vibrating tube. The mechanism is simple and small enough to realize reduction of the weight and total volume of VFP. Two types of VFP have been developed in this study. One is designed for ventricular assist device (artificial heart blood pump). The inner diameter of vibrating tube is 16mm and the pump output was 4.9 l/min. The other is designed for coronary perfusion blood pump. The inner diameter of vibrating tube was 4 mm and the pump output was 25 ml/min. The weight of the pump head and motor was 50 grams.
