ABSTRACT
ABSTRACT: The article discusses the design of actuators pump systems of left ventricle assist device. Presents the results of fusion power for the drive systems, of left ventricle assist devices.
1 INTRODUCTION
The implantable Left Ventricle Assist Device (LVAD) used a pulsating type pump modulesMechatronic Drives (MD) comprising a multi-pole DC motor valve, working in reverse mode, and an Actuating Mechanism (AM) convert rotary motion into linear (Morozov, 2006). Currently, the most common and reliable design of these modules are AM Roller Screw Mechanism (RSM), and as the DC motor used torque multi-pole motors. Examples of such structures can be: Baylor LVAD, TAH, USA (RSM); Yamagata LVAD, TAH, Japan (RSM); Japan Hokkaido LVAD (BSM); Swiss LVAD, Switzerland (RSM), and others. (Morozov, 2005) The design of such systems is only possible with the combined influence of the DC motor and AM. To accurately determine the parameters of AM and DC motor it is necessary to limit the synthesis according to the criteria of dynamic capabilities, low Power Consumption (PC).
