Abstract

Intravenous (IV) fluid therapy is one of the basic procedures applied for the infusion of fluid, medicine and nutrients to patients. Continuous measurement of IV fluid level is necessary for avoiding risks like dehydration, blood reflux, air embolism and discontinuation of therapy. The current practice for measurement mainly involves manual observation of healthcare staff at regular intervals, which might delay the response in case of emergency due to workload in clinical settings. Hence, in order to resolve this problem, this paper proposes an Internet of Things (IoT) based Intra Venous (IV) Fluid Monitoring System with Real Time Alert and remote supervision of IV fluid therapy. The proposed design involves 5 kg load cell, HX711 amplifier, ESP32 microcontroller, LCD screen, buzzer and Blynk platform to monitor IV bag weight, measure the remaining amount of fluid in the bag and communicate the information wirelessly to the healthcare personnel. Alerts are set based on threshold values and generated both locally and remotely if the level reaches the critical value. The experimental testing proved that the system has an accuracy rate of 98.7%. The system exhibited reliable synchronization in the cloud, quick notifications, and consistent real-time operation, thus proving to be a cost-efficient, scalable, and effective approach towards enhancing patient safety.
