Story

Introduction

All around the world due to the COVID-19 pandemic many people are not getting the required medical attention. Doctors are not able to manage the medical resources and due to this, our current medical framework is collapsing.

In my place, Hyderabad, India many of the patients are not able to get admission into hospitals and they are in-home quarantine. But, if there was a way for a doctor to monitor these people remotely and with less effort, they would be able to help these people better.

Proposed idea

Using a simple wearable device and a software platform we plan to integrate the patient data into a platform and make processed data available for a doctor.

The product we designed collects patient data via a wearable, transmits them to a data aggregator via BLE, and then the aggregator pushes it to a server where a machine learning model generates inference. This along with the patient data is displayed on the doctor's computer.

Advantages

1) Simple and easy to use

2) Helps manage patients more efficiently

3) No extra efforts needed

Machine Learning Core

This notebook is hosted on intel dev cloud where we used the Intel(R) Xeon(R) Gold 6128 CPU @ 3.40GHz as the core compute instance. The model is basically a Decision Tree Regressor that was trained on data partially collected from a kaggle dataset and partially from real-life sensor data.

ECG Sensor interfacing

void setup() {
Serial.begin(9600);
pinMode(10, INPUT); 
pinMode(11, INPUT); 
}
void loop() {
if((digitalRead(10) == 1)||(digitalRead(11) == 1))
{
Serial.println('!');
}
else{
Serial.println(analogRead(A0));
}
delay(1);
}
