Syringe Infusion System

Abstract

Directing medication to patients through the oral, intravenous means is a vital notion for the handling of sicknesses in medical field. Conventionally, medication to the patients is delivered by the System in which a drip to a patient’s body is infused through a hanging bottle with a roller attached to the pipe. This is a popular means of transferring a fluid into a patient’s body and is known as Roller Clamp Delivery System. Roller Clamp is used in almost every hospital for providing Glucose, Blood etc. While there is a drawback with this system that flow of liquid is controlled by the force of gravity. Although roller in pipe can be used to regulate the speed it does not tell about the flow rate of the fluid infusing into a patient’s body. So, this system can cause serious health problems if flow rate is not set accordingly. An overcome to this system is Position Controlled Infusion Pump. PCIP is designed using a stepper motor, and by controlling the speed of stepper motor flow rate can easily be controlled. In this project, we include a syringe in it which is used for the transport of small amount of drug. It has a microcontroller set in it which controls the flow in these pumps. A stepper motor in it which gives a precise delivery of liquid. Stepper motor with greater resolution the less will be the drop size. Hence Syringe pumps are dependent on the stepper motor for their precision. It is also interfaced with an LCD in them which shows the flow rate of system. This can also be used with various sensors for their best use. They will be of great use soon after replacing Roller Clamp Delivery System.
