Optocoupler Berbasis Mikrokontroller ATMEGA 8535 pada Perancangan Sistem Kendali Otomatis Tetesan Cairan Infus pada Pasien

Abstract

The function infuse which is to give intravenous fluids to patients on a regular basis Mistakes in giving intra venous fluids may be detrimental to the patient, also if there are problems with blockage or running out of liquids if not immediately addressed would be dangerous for patients. Infuse the current user is still manually where mistakes – mistakes such as these are still common, there fore we make an infusion control device design that can work automatically and digitally monitoring. In this final project will be designed a control system and periodic monitoring of infusion and the physician or nurse need only enter the desired number of droplets from the keypad. Sensor used in this tool is an optoucoupler While the pressure hose is used instead of motor stepper At the end of the project is used as microcontroller ATmega8535 pulse generator to control the stepper motor and circuit condition Buzzer Alarm as droplets LCD and keypad as an interface that allows the physician to control and ease in usingthis tool. The test results for calculates number of droplets a second infusion posses an average accuracy of 80 %
