Design and development of a monitoring and controlling system for multi-intravenous infusion

Recently, many of conventional infusion control tools which has functions to control the drops of infusion fluid and to monitor the volume of infusion fluid. Because it work manually, it has low level of accuracy and low efficiency. So that, in this research has designed a device that could monitor and control the drops of infusion fluid for multipoint (multi intravenous) through online application. On hardware part, photodiode and LED was used to detect the drops of infusion fluid, a sliding potentiometer and simple modified spring was used to detect the volume of infusion fluid. In this research was also implemented a mechanical which use motor servo to set the speed of drops of infusion fluid. WEMOS and MCU node has been designed as main control to controlling the whole of system. The device was equipped with ESP8266 as interface to internet network. An administrator can monitoring and controlling the system through offline or real time through a website application that has been built. based on the testing result, as functionality the system was working well. The device could detect the drops of infusion fluid with 100 % of accuracy and could control the volume of infusion fluid with 99 % of accuracy. Total of maximum drops per minute that could detected by system was 135 DPMs with average of transferring delay was 1.95 second.
