Post COVID health monitoring system

Abstract

This report describes the implementation of a final year design project named “Post COVID Patient Health Monitoring System” which also contains report out lines, major design changes, testing data, final budget, project validation, working process of project. Motivation of this project comes from listening to a close family member of a friend who was 68 years of age who died because of lack of proper monitoring after being affected by COVID 19 in 2020. As we all know that COVID 19 is a breathing problem related to diseases which affect major organs in our body. Mainly affects the breathing system. Around 30% people died after coming from the hospital as they were Post COVID patients. This project helps people to look after their beloved ones when they are out of home or unavailable to look after. It can reduce patient monitoring costs. This project measures three parameters of the patient's body which are always needed to monitor. Heart rate/ Pulse Rate, Oxygen Level and Body temperature are the three parameters this project will measure. Firstly, we did a software test using the components we want to use in hardware. Software trials need proper coding for simulation. We modified code as our desired one then put the Hex file in simulation software and ran the software project. After getting clearance that software simulation is almost ok we recheck the codes and modify them where necessary then again put the Hex file in simulation software name proteus. Then exact results got by simulation it's like closer to the medical equipment value used in hospitals. Before making hardware we made a 3D design where all the hardware showed accurately. The next step is hardware implementation. In the hardware part running all the components at a time is very challenging for us because we are not professional on this. So we finalize the components then use soldering iron to join the components together. We try to run the components each time it burns out. Then we get a solution that uses a Li-On battery so that we can protect components from burning. Another challenge we face is to settle all these components in the same case so that we can fit this case in the wrist of a patient as our project is based on wristbands. We use ESP8266 D1 microcontroller for data processing, SIM800L for GSM module as communication, 6DOF MPU 6050 3 AXIS GYRO for patient movement monitoring for X, Y & Z axis, MAX30100 for measuring heart rate/ Pulse rate also oxygen level, NTC 103 this is a temperature sensor which will give body temperature this processing system store data to local server known tingspick. This server will process data and if it gets any uncertain issue then send S.M.S through the GSM sim module to patients, family members and doctors. This full process was done in PCB design which cost 4500 tk. The last edition update of this project is that we add a push button for emergency purposes only. When we figure out our component work is pretty much correct then we try to fit this in a plastic case so that we can make this project usable. so we order a 3CM*3CM*3CM plastic case from the market and a set of watch belts to make it wearable. Then we go for a test case. According to eight test cases we find out that six test case data is partially similar to exact data measured in hospital of a post covid patient. so this product will follow a good quality model and be cost friendly as well. Lastly, this project contains an additional budget of 1500 taka and a project budget of 8150 taka so the total costing of this “Post COVID Health Monitoring System - (OXY- Cardio Wristband)” is 8176 taka.
