Abstract:
-This study focuses on automating the blood typing process for ABO and Rh Groups, which is currently and more often, done manually by medical technicians. This system is microcontroller-based, particularly using Microchip’s P16F84. It uses three reflective color (optical) sensors to detect the presence or absence of agglutination in the blood. The automation process consists of using motordriven belt-type tray mechanism that moves in the X and Y axis, solenoid valves that actuate the dispensing of anti-serum reagents onto the blood and DC motor mixers to combine the blood and reagent. A supertwist nematic type of LCD, controlled by P16F84, is used to display the blood type and rhesus factor as determined by the system.
