Blood Detection in Infusion Hose Using Fuzzy System

The use of infusion in medical is an important thing since infusion fluid can replace the lost body fluids rapidly and the infusion fluid is easily absorbed by the body. In the use of infusion, it must be observed periodically to avoid run out of infusion fluid or the blood clotting in an infusion hose. In the case of blood clotting detected in the infusion hose, the blood can clog the blood capillaries in the lungs and causes an embolism in the lungs. A warning system is needed when the infusion is impaired to prevent the blood clotting due to depleted infusion fluid. In this research, we propose an infusion monitoring device by using a color sensor to monitor the blood rises to the infusion hose. If there is blood detected in the infusion hose, the sensor will notify the warning by the buzzer and LED light. The color detection by sensors uses a fuzzy logic method. The results show that the sensor accurately sends a notification through the buzzer and LED light when blood is detected in the infusion hose with the average uptime of the buzzer and LED light is 5.6 seconds.
