One of the biggest concerns that many people have - especially as we get older or if we have older relatives - is what we will do if there is some kind of medical emergency when we are alone or our older loved one is alone. Medical alert systems have been around for a while, but the best ones are monitored medical alert systems.
In recent times, it has become necessary to have a system that constantly monitors a patient’s heartrate and body temperature autonomously and then send an alert when readings are out of range to ensure healthcare is always provided on time. People are dying from heart related diseases like coronary heart disease, congestive heart failure, heart attack, and congenital heart disease especially the aged who need 24 hours monitoring. Body temperature is a vital sign that medical professionals measure to help them determine the condition of their patients. Body temperature is a vital sign that medical professionals measure to help them determine the condition of their patients. The normal temperature of the body is dependent on a recent activity, time of the day, age and ranges from 36.1 degrees Celsius (97 degrees Fahrenheit) to 37.2 degree Celsius (99 degrees Fahrenheit) for healthy adults. A wearable device, accompanied with an android application, monitors the temperature and heartrate of the user. The system has sensors to measure body temperature and heartrate of the user and displays them on (mobile phone) screen. These values are then sent to the user’s phone via Bluetooth to be stored. When the values recorded are abnormal, a LED light lights up, a buzzer sound and an alert is sent to a confidant of the user with his/her location.
IoT health monitoring systems prevent frequent visits to doctors and meetings between patients and medical professionals. However, many individuals require regular health monitoring and observation through medical staff. In this proposed work, we have taken advantage of the technology to make patients life easier for earlier diagnosis and treatment. A smart health monitoring system is being developed using Internet of Things (IoT) technology which is capable of monitoring blood pressure, heart rate, oxygen level, and temperature of a person. This system is helpful for rural areas or villages where nearby clinics can be in touch with city hospitals about their patient health conditions. However, if any changes occur in a patient’s health based on standard values, then the IoT system will alert the physician or doctor accordingly. The maximum relative error (%ϵr) in the measurement of heart rate, patient body temperature and SPO2 was found to be 2.89%, 3.03%, 1.05%, respectively, which was comparable to the commercials health monitoring system. This health monitoring system based on IoT helps out doctors to collect real-time data effortlessly. The availability of high-speed internet allows the system to monitor the parameters at regular intervals. Furthermore, the cloud platform allows data storage so that previous measurements could be retrieved in the near future. This system would help in identifying and early treatment of COVID-19 individual patients.
IoT-based
health monitoring system differs from the normal healthcare system in a very
efficient way. Therefore, it becomes a bit challenging to achieve the required
results and performances through IoT. Working with IoT is related to the
embedded world as the sensors use electronic data signals. Initially, devices
such as sensors, detectors, monitors and microcontroller are connected
altogether for synchronization. The sensors and detectors detect the signals in
analog form, which needs to be further converted into digital form. The inbuilt
analog to digital conversion is performed through the microcontroller to get
data in proper digital format. The data are sent to Raspberry Pi that is being
used as a microcontroller. Nowadays, the Raspberry Pi is most commonly and
widely used in Internet of Things. After the conversion of data, storage of
data is performed. The data are being sent to the cloud or server. In this
research, a local server is used, which shows the variations of the values, or
the readings measured simultaneously.
In conclusion Smart health monitoring system provides ease to the doctors to identify the patients' information individually simply on the display monitor at their place. Doctors can distinguish the data of the particular patient regarding previous values with the present one. Along with data logging on the cloud, the Internet of things also provides opportunities to add more advanced features or benefits and more biomedical sensors to this system. Therefore, the technology of IoT makes this monitoring system more flexible and more updatable in future. In this proposed work, we have taken advantage of technology to make patients' lives easier for diagnosis and treatment by monitoring a person's blood pressure, heart rate, oxygen level, and temperature etc.
