Abstract
The Combinations of artificial valves and the driving methodes for the pulsatile blood pump have been studied employing mathematical model and mock circulation to increase the pump efficiency with smooth valve action.
These model analysis and mock tests revealed that the pulsatile pump has the optimal driving condition, under that the pump can eject the maximal output with smooth movement of the valves, and that the optimal combination of valves is a tilting disc valve for the inlet, and a ball valve for the outlet.
The optimal driving conditions of the pump for clinical use are as follows;
pulse rate=80cpm,
systolic time=0.35sec,
supply air pressure=0.6Kg/cm2,
vacuum pressure=-100mmHg.
These findings enable the pump output to increase up to 6L/min without any complications.
