A Holistic Approach For Patient Health Care Monitoring System Through IoT

Health care is the most important aspect of any society and is fundamental need for every citizen of every country. However, most developing countries face lack of proper health care resources to cater to the needs of every citizen. In critical cases, the patients have to be continuously monitored for their bio-parameters and immediate response from doctors is essential. So, it is most essential to improve the healthcare infrastructure. The emerging trend in healthcare sector is to change the existing healthcare services and change the routine medical check-ups from hospital centric to person centric. Here, A Holistic Approach for the Development of Real Time Patient Health Monitoring and Alerting through IOT is proposed and implemented using ThingSpeak site as the cloud. This work presents the design and construction of a working prototype for smart health care system using Internet of Things which can provide Quality Health Care to everyone. In this system, the prototype developed uses an embedded system built using Atmega328 microcontroller and it is programmed using Arduino IDE. The prototype gathers biomedical and orientation information from sensors and location information from GPS of the monitored person and convey them to healthcare cloud system utilizing IOT platform. The sensor data is sent to the network through Wi-Fi link. The Thingspeak channel is updated at regular intervals and helps to maintain the medical history of the patient. The Thingspeak cloud computing handles authentication, privateness, safety, and data management and provides accessibility. The system obtains the parameter valus and compares them with the standard values and in the case of an emergency, a local alarm is triggered and an SMS text message is sent to the doctor with the details of authentication. The data from cloud platform can be accessed by the concerned doctor anytime, after a proper authentication and diagnosis and decisions can be made. The data can be accessed only by the authorized user (doctor) through password authentication.
