Design and Control of Electronic Syringe Pump using AVR Microcontroller

Abstract

The infusion and retract rate of the electronic syringe injection pump is one of the major challenge in the designing and control of electrospinning system. The selective droplet materials of a small size with controlled structured and patterned is released through a needle of the syringe pump very important. This investigation focuses on control parameter like infusion and retract rate, flow rate, the droplet volume, and syringe size dimension. It is observed the infusion rate 1ml for 5.7sec to 7.11 sec, retract rate 1ml for 1600-2000 signals pulses of stepper motor, the droplet volume is 0.0001 to 0.02ml increasing after every 300-500 signal pulses observed on CRO with different types of syringe injection pump. It is observed that the average error for the measured flow rate is 10% and average error for the measured volume is 1.91%. In this study the design and control of low cost and simple system is discussed using prototype of electronic syringe injection pump designed using AVR microcontroller for changeable and small delivery rates for the control of low volumes.
