Health Care IoT Monitoring System

 Health Care IoT Monitoring System


I am Mohamed Hussain from Sri Lanka. I successfully developed an IoT system for our IoT subject at Solent University, UK. This system is a Health Care IoT Monitoring System.

Abstract

Health care IoT monitoring system is monitor the patient's physical health. that is the patient's body temperature, heartbeat level, and blood glucose level. The data of this device can be tracked directly through the IoT cloud platform. This system has  DHT11, Pulse Sensor, and Glucose Sensor used. this device's All components are assembled in the PCB (Printed Circuit Board). With this device, doctors can monitor a patient's body temperature, heartbeat level, and blood glucose level. The purpose of this device is to reduce the death rate of patients in the hospital, to improve and maintain the physical health of the patients, and to improve the development of the medical field.

Introduction

This system has two devices one is the main device it will be fitted to the patient and the DHT11 sensor, Pulse sensor, and blood glucose sensor be connected to this device. Another device is the receiver device it only receives the messages from the chief doctor by cloud platform via the main device. this device will be in the hands or staff room of the assistant doctors. the smart Health care IoT monitoring system, we have to create a smart unit ward room with all facilities in a hospital. Once a patient is admitted here. then we have to fit these 3 sensors on the patient's body then the patient’s heart rate, blood sugar level, and body temperature are monitored directly by a chief doctor assigned to the hospital’s smart unit through the IoT cloud platforms. if the patient's health condition is adverse, the chief doctor will press the proper button in the cloud platform. Then the signal will go to the main device from the IoT cloud platform then the main device will send the signal about the patient's health level to the receiver device then the assistant doctor will directly go to the patient and take treatments.

Problems 

Sudden heart attacks, high blood sugar levels, etc. are the leading causes of death, and nurses who monitor patients in the hospital can potentially cause fatalities if they are unable to fully comprehend the patient's symptoms at all times. Spending too much time to testing the heart rate, body temperature, and blood glucose level of a patient once admitted to the hospital. And each experiment must be done separately. Some one-time tests, such as blood sugar testing, are difficult to analyze.

But with this Health care IoT monitoring system can quickly test and analyze the blood glucose level, heart rate level, and body temperature level. So, the main purpose is to improve the health of the patients with this device.

Aim

Providing solutions to maintain and protect the patient’s health and life by this Health care IoT monitoring system.

Proposing an IoT model

The medical field is growing day by day. However, more lives are being lost, and caring for hospitalized patients at a time in hospitals can be a daunting task. These problems can be solved with the IoT system proposed here. Once a patient is admitted to a hospital, doctors will first examine their heart rate, body temperature, and blood sugar level separately. With this system, the data of these three experiments will be instantly monitored directly on the IoT cloud platform. This system prevents wastage of time and immediately reminds nurses of any adverse changes that may occur in the patient's health.

Design of IoT Module

System Diagram

This diagram has two main parts that are main device and the receiver device. the main device will send the data to the IoT cloud platforms via the MQTT protocol by the internet. then the emergency button is pressed in the platform, the signal will again go to the main device and then the main device will send information to the receiver device via radio signal by the Nrf24l01 transceiver. 

Virtual Diagram

This is a virtual diagram of an IoT system. This system shows how to connect to all parts and the internet.

EasyEDA PCB Design Software

In this project, I used EasyEDA software to design the PCB (printed circuit board).


Data Visualization

In this system, all data was saved in the IoT platforms. the platform has data storage and data will save here. we can easy to download the data.

The pulse sensor was added to the Ethernet shield and data send to the cayenne IoT platform and visualized.

Data analysis

The collected data from the sensors is saved in the IoT cloud platforms, then platforms will analyze the data and display it on another page. we can download the saved data sheet in the IoT cloud platforms, then we can use different analyzing software and tools to analyze and display it. for example Microsoft Power BI tool.
