In rural regions of Bangladesh, the scarcity of healthcare resources poses a substantial obstacle, frequently resulting in delayed diagnoses and inadequate medical care. This paper introduces an inventive solution, the “IoT-Based Rural Area Portable Diagnostic and Medication System,” designed to address these healthcare disparities by harnessing the capabilities of Internet of Things (IoT) technology. This system leverages IoT sensors and devices to enable remote health monitoring and diagnostics for residents of rural and underserved communities. It comprises a network of portable medical devices, such as wearable sensors, diagnostic tools, and medication dispensers, seamlessly connected through MQTT protocol to a centralized healthcare platform. Through this system, healthcare providers can remotely monitor patients’ vital signs, track disease progression, and deliver timely medical interventions. Moreover, the system ensures the secure and confidential exchange of sensitive medical data and enhances transparency between physicians and patients through the utilization of blockchain technology.
