A portable volumetric infusion pump controller for treatment of thallassemia disease

Abstract

A design study of a VLSI (very large scale integration) implemented volumetric infusion pump controller with enhanced performance compared to conventional designs is presented. The proposed system is composed of the designed controller and electromechanical equipment consisting of a dc motor, a magnetic drum, and a Hall effect sensor. Medicine dose settings are altered using a keyboard and are processed by the controller to produce the pulses that activate the motor. In advance, the controller supervises the device over all operations performing all the necessary control and fault handling. In this paper, we provide a technical description of the device developed which has a reduced size, power consumption and overall cost, as well as increased reliability and fault tolerance, compared to former implementations.
