Smart Intravenous Drip Monitoring System with Bubble Detection Indicator using IoT

With the increasing emergence of new diseases and ailments, health care facilities are gradually becoming an integral part of our lives. The most important thing in these healthcare facilities is safety of the patients. With an ever increasing population, automatic health monitoring systems are gaining importance too. They are highly sought after since they provide exact information while remaining cost-effective and minimizing medical practitioners' and patients' stress. Among various health procedures, intravenous therapy is an often used medical method to deliver fluids, medications and nutrients into a patient's veins. It requires manual monitoring by the medical staff and negligence can cause fatal risks. Further, with COVID-19, the burden and pressure on medical professionals increased manifold which enhanced the chances of negligence. The aim of this paper is to create a practical, budget-friendly and Internet of Things based monitoring device for intravenous therapy. The proposed system consists of a light dependent resistor for detection of fluid level in the IV drip bottle and air bubble formation in IV tube. When the fluid in the IV drip bottle reaches a critical level or air bubble is detected, a notification will be received by the concerned staff. Also, an auditory and visual alert will notify the people present in the patient's room. This will enable the medical professionals to immediately attend to the patient without the hassle of periodic monitoring.
