Intravenous(IV) Bag Monitoring System

Intravenous (IV) therapy is a critical medical procedure, but its manual monitoring by frontline workers poses risks of complications like backflow of blood or fluid imbalance due to changes in drip rate or bag depletion. This paper proposes the design and implementation of an IoT-Enabled IV Bag Monitoring and Control System for hospitals. The system uses a load cell sensor (specifically the HXT711 Weight Sensor ) to continuously monitor the IV bag’s weight, which is then used to infer the fluid level and dispensing rate. An Arduino NodeMCU processes the sensor data and transmits it to an IoT Cloud (Blynks) over the HTTP protocol. The system is designed to provide alerts via mobile application notifications at a preliminary threshold (e.g., 15% fluid remaining) and activate a buzzer alarm for critical levels to prompt immediate nurse intervention, thereby significantly reducing the workload on nursing staff and minimizing the risk of medical emergencies associated with unmonitored IV administration.
