Abstract:
Objective To observe the response of the guiding vane to axial flow pump by testing two types of miniature axial flow pump,which have been developed by our group in recent years.Methods Two types of axial flow pump were tested in a mock circulation apparatus.Results The outputs of the two types of miniature axial flow pump all attain 5L/min against the pressure of 13.332kPa,which is enough for left ventricular assistance.The outputs are similarly related to their pre-load and after-load pressure.In this study,the guiding vane does not produce a significant affection on the hydrodynamic characteristic of the axial follow pump.Conclusion The guiding vane may be neglected in the design to improve the blood compatibility of a axial flow pump heart assist device.
