A FPGA-based implementation of an intravenous infusion controller system

Abstract

In this paper we present the development and implementation of an intravenous infusion controller system based on FPGA's. The system receives information of an infusion drop sensor and controls the drop flow by giving the direction and number of steps of a stepper motor, which compress the drip-feed hose. The system consists of a mixed implementation of software and hardware. The software was implemented in C++ and the hardware was implemented by using FPGA's.
