Development of Control System for Assisted Circulation Apparatus of Artificial Liver Support System

An advanced control system used in assisted circulation apparatus of artificial liver support system was developed based on embedded platform and field bus. This system consisted of a cardiopulmonary bypass-controlling system, a blood circulation and reactors status-monitoring system, and a human-machine interface and communication system. Multiple functions are implemented such as on-line monitoring, controlling and driving of the assisted circulation apparatus, real-time supervising and regulating of the physiological environments in reactors, and convenient, rapid operation mode, with high security, stability and practicality. The implementation of this system is helpful to the independent construction and evaluation of artificial liver support system, as well as the research works on hepatocyte culture and bioreactor design.
