APPLICATION OF CAD/CAE-TECHNOLOGIES FOR WORKING OUT OF A UNIVERSAL DESIGN OF AN ARTIFICIAL VENTRICLE OF HEART

Objectives: Working out of a universal design of an artificial ventricle of heart (AVH) for devices of auxiliary blood circulation with an electromechanical and pneumatic drive for application in extracorporeal and implanted systems. Methods: For the decision of the given problem methods of computer modeling were applied to definition of geometrical parameters of AVH and methods of the certainly-element analysis for a finding of optimum hemodynamic parameters of work of AVH. Geometrical modeling was spent in system Pro/Engineer WF 4. System Ansys was applied to the analysis of a current of fluid in chamber of AVH. Modeling was spent with both a moving, and a stationary membrane with the task of beginning and boundary conditions. The system was put to the test on the test bench for definition of an output and an imaging of a current of fluid in chamber of AVH by application the laser set, which works by cooper steam, model CVL-10 ( lambda = 510 nm, Russia), and high speed camera, model CCD - SMOS VS - FAST (speed of shooting 5000 fps, Russia). Results: Hemodynamics key parameters, giving the chance to optimize a design by hemodynamic indicators, are defined. Conclusions: The model of optimum design of AVH for application in considered designs is received.
