InflataCare - Bedsore Prevention System

Overview

InflataCare is a comprehensive product designed to combat bedsores among elderly and bedridden patients. By monitoring pressure points and providing automated inflation controls, the system helps prevent pressure ulcers that develop from prolonged periods in the same position. This web application interfaces with Arduino IoT Cloud Server to visualize pressure data in real-time and allows caregivers or patients to control inflation settings to redistribute pressure as needed.

Installation

Prerequisites

• Node.js (v14.0.0 or higher)
• npm (v6.0.0 or higher)
• Arduino IoT Cloud account
• Arduino devices with pressure sensors and inflation pumps

Setting up the development environment

1. Clone the repository:

   git clone https://github.com/yourusername/inflatacare.git
   cd inflatacare

2. Install dependencies:

   npm install

3. Set up Arduino IoT Cloud

   a. Create an Arduino IoT Cloud account Go to Arduino IoT Cloud and sign up or log in.

   b. Create a new Thing

   • Click on "Create Thing".
   • Give it a name (e.g., InflataCareThing).
   • Add a device (choose your Arduino board or set up a virtual device).
   • Add variables (e.g., pressure, isInflating) and set appropriate types and permissions (Read/Write, etc.).

   c. Link to a new Sketch

   • After creating your Thing, Arduino Cloud will automatically generate a sketch.
   • Open the sketch in the Web Editor or Arduino IDE.

   d. Copy and paste your code

   • In your project, locate the Arduino sketch folder (typically found under /arduino_code or similar).
   • Open the .ino file.
   • Copy its contents and paste it into the Arduino Cloud-generated sketch.
   • Add your own WIFI key and password in Sketch Secrets file.

   e. Verify and Upload

   • In the Web Editor, click Verify to ensure the code compiles.
   • Connect your Arduino board and click Upload.
   • Make sure the board connects successfully and your variables appear on the dashboard.

   f. Get the required credentials

   • On the Thing page, click on the three-dot menu > API Keys.
   • Generate and copy the Client ID and Client Secret.
   • Copy the Thing ID from the Thing’s URL or settings.

   For more information on setting up the Arduino hardware, please refer to youtube video on how configure your arduin to the IoT Server.

4. Set Up Arduino IoT Cloud Server: Create a .env file in the project root and add your configuration:

   VITE_API_URL=http://your-server-address:3000
   CLIENT_ID=your_client_id
   CLIENT_SECRET=your_arduino_api_key
   THING_ID=your_thing_id
   PORT=3000

5. Start the backed development server:

   cd inflatacare_backend
   npm start

6. Start the frontend development server:

   cd inflatacare_frontend
   npm i
   npm run dev

Production deployment

1. Build the production version:

   npm run build

2. Deploy the contents of the dist directory to your web server.

Usage

Pressure Monitor Dashboard

• View real-time pressure readings from all sensors
• Monitor accumulated pressure time for each point
• Observe visual alerts when thresholds are exceeded

Inflation Control

• Select a body section (T, L, R) to activate controls
• Choose inflation levels (0-4) for the selected section
• Set the patient's position based on medical requirements

Settings Configuration

• Set maximum weight threshold (recommended: 60-80g)
• Configure maximum time threshold (recommended: 20-40 minutes)
• Enable/disable notifications
• Toggle dark mode and auto-connect features

Arduino Integration

The system connects to the following Arduino IoT Cloud properties:

• fRS1 through fRS6: Pressure sensor readings
• highestAccTime: Highest accumulated time above threshold
• alertStatus: Bit-encoded status for all sensors
