Design of automatic infusion monitoring system based on Arduino

Intravenous Fluids Drops are very important for the process of healing or treatment for patients. The function of infusion is to replace the loss of fluids or nutrients in the body. In Indonesia, monitoring system of condition about infusion is still done manually, but for the cases such a large hospitals which is the number of patients is not balanced by medical personnel, it is becomes ineffective so that it can cause mistakes in monitoring. A very serious mistake can occur are too late in replacing the infusion. The solution to solve this problem is to make an automatic infusion monitoring system with an alarm warning. This research is experimental research. The measurement technique taken is direct and indirect measurement. Direct measurement data is mass of infusion and indirect measurment data is the number of infusion drops and the percentage of remaining intravenous fluid. The purpose of this research is to determine the design spesifications and peformance spesification of the instrument. The sensor used to measure infusion drops per minute is photogate and to measure the infusion volume is load cell. The display is use TFT LCD and using buzzer for alarm warning. The accuracy of infusion drops per minute system is 0, 97 with error 2, 15% and accuracy of infusion fluid percentage system is 0, 98 with error 1, 47%.
