Design of an Extracting air Control System in Hemodialysis Machine using Microcontroller

Abstract

This project is a try to make people pain shorter using embedded system technology to design a module to control draining of air bubbles is the blood on hemodialysis machines. The module is consist of amega16,infrared transmitter and receiver diodes ,and valve, this module will be added before the sensor of air detector infrared sensor will detect if there is air bubble or not, if there is any the microcontrollerwill switch the valve to drain the blood that containing air without nurse interference. the blood with air bubbles will be drained to the sub part that will extract the bubbles and return again to normal blood path. The obtained result encouraged to design the module and use it as a powerful tool along with hemodialysis machines in order to make patients suffer less.
