An IoT-Enabled Smart Medical Bed for Monitoring Patient's Health

The growing demand for healthcare personnel, combined with the increasing elderly population, highlights the need for more efficient and automated patient-monitoring solutions. Conventional monitoring requires frequent manual checks, making the process intrusive and labour-intensive for medical staff. This paper presents an IoT-enabled smart medical bed designed to monitor key physiological indicators using integrated sensing modules. The system focuses on elderly patients, who represent a large proportion of hospital admissions and require close monitoring of vital parameters. The proposed design captures heart rate, oxygen saturation, body temperature, and pressure through embedded sensors, transmitting the collected data to the Blynk platform and displaying it locally on an LCD panel. By enabling continuous, real-time observation of multiple patients, the system reduces the need for constant room visits by nursing teams and allows timely intervention when abnormal readings are detected.
