Such deliveries are commonly achieved using syringe pump which generally employs syringes driven by an electric motor. In this work a syringe pump is operated with a Raspberry Pi - System on Single Chip, which is more user friendly than a control with an ordinary microcontroller. It runs on Linux platform which is easy to code and control using Python language. The syringe pump is actuated by stepper motor which has 200 steps per revolution so that precise flow rate is possible compared to other electrical actuators. The stepper is connected to a Dual H- Bridge L293D motor driver, which in turn is powered through the GPIO (General Purpose Input / Output) pins – an integral part of the Raspberry pi. Lead screw mechanism is used in this work to transmit rotary motion of the motor to linear motion of syringe. The pitch length travelled by the screw is minimal and controllable, resulting in a precise flow rate of the fluid which is measured experimentally. I. INTRODUCTION Syringe Pump finds its applications in various areas such as Healthcare, medical and pharmaceutical industries. In therapeutic centers syringe pump is used in diffusion of drugs through blood which is mainly anaesthetic and hormonal drugs. In PET (Positron Emission tomography) scan, radioactive medicines are injected in to the body through a syringe pump and X-Ray images are taken. In Chemical and process industries, a syringe pump is used for critical titrations where a chemical quantity needs to be more precise. Syringe pumps are also used in micromachining and in places where controlled flow rate is essential. Miller et al [1] designed a modified syringe pump and called it as a High Performance Silicon Pump for drug delivery system. In Ref [2] it was observed that responsiveness of syringe was increased by decreasing the volume of the syringe. Zida Li et al [3] observed that the responsiveness of the syringe pump was affected by fluidic resistance and low flow rate. Appaji et al. [4] worked on single acting Syringe pump control using 8085 microcontroller. In 8085 micro controller debugging and error detection was complex and involved hexadecimal coding system. So in the present work raspberry pi is used which is system on single chip and more versatile than 8085. Actuating mechanisms for syringe pump play a major role in control of the syringe pump. Tarng [6] did a kineto static analysis of lead screw mechanism. In Ref [7] it was observed that linear control of lead screw was possible with low speed devices with precise movements. In lead screw mechanism the motor shaft was connected to a threaded screw and while it turns, it moves the nut forward or backward and also the piston connected with it. Thus the shaft movement governs the delivery of fluid in a controlled manner. The piston generated a hydrostatic pressure, which delivered the fluid into the chamber.
