摘要：

The paper presents a wearable control system for the electromechanically driven blood pump, the Novacor left ventricular assist system (LVAS), developed for the ambulatory patient. Ergonomically designed for portability, comfort and appearance, it offers the recipient greater mobility, improved self-image, and an enhanced quality of life. The system consists of a microprocessor based compact controller that drives the implanted pump/drive unit in synchronous counterpulsation to the native heart. Main and reserve rechargeable power packs, each incorporating a smart monitoring circuit with charge level display and alarm, are capable of supporting the pump for as long as 7 hr.
