Inspiration

In India, over 10,000 children are born each year with Thalassemia Major, a severe, inherited blood disorder that requires lifelong blood transfusions every 2–3 weeks just to survive. [https://iapindia.org/thalassemia/]

But for many families, each transfusion becomes a crisis. We've heard of parents posting desperate pleas on social media, traveling across cities to find matching blood, or waiting helplessly in hospital corridors while their child’s condition worsens.

Even with systems like e-RaktKosh, donor-patient matching is often reactive, not predictive. There's no AI to forecast donor availability, no proactive nudging of registered donors, and no multilingual chatbot to support rural families during emergencies.

We built RaktaFlow to change that — → To predict need before the crisis, → To match donors in real-time, → And to make life-saving help proactive, empathetic, and accessible.

Because missing a transfusion shouldn’t be the reason a child doesn’t make it.

What it does

RaktaFlow is an AI-powered blood donation coordination platform that helps Thalassemia patients receive timely transfusions by intelligently connecting them with potential donors and care providers.

Features:

  1. Predictive Donor Availability: ML models trained on past behavior, blood group demand, location, and seasonal patterns.
  2. Real-Time Donor Matching: Instant alerts to registered, eligible donors based on proximity, compatibility, and urgency.
  3. Multilingual AI Chatbot: Supports patients and families in Hindi, Gujarati, and English to request help or get updates.
  4. Gamified Donor Retention: Points, badges, and impact stories to encourage repeat donations.
  5. Integration with e-RaktKosh & Blood Bridge: Seamless syncing of donor data and blood bank inventory in real time.
  6. Privacy-First Architecture: Encrypted communication, zero patient data leakage, and GDPR-inspired practices.

How we built it

Frontend: React.js, Tailwind CSS Backend: Node.js, Express.js, MongoDB AI/ML: Python (scikit-learn, XGBoost), TensorFlow Lite Chatbot: Dialogflow or Rasa (multilingual support) APIs: e-RaktKosh Public APIs, Twilio/WhatsApp, Google Cloud Translate Deployment: Firebase / Vercel / Render Security: OAuth 2.0, HTTPS, data encryption (AES)

Challenges we ran into

  1. Ensuring data privacy and compliance with health data standards.
  2. Integrating with fragmented or outdated hospital systems.
  3. Encouraging repeated donor behavior through non-financial incentives.
  4. Multilingual NLP challenges for rural coverage.
  5. Real-time sync and latency with live blood bank systems.

Accomplishments that we're proud of

  1. Designed a holistic, scalable solution that addresses critical gaps in India’s blood donation ecosystem, specifically for Thalassemia patients.
  2. Created an AI-powered prediction system that proactively identifies donor availability and patterns — going beyond standard blood matching.
  3. Conceptualized a multilingual, accessible platform with chatbot assistance, enabling underrepresented and rural families to get support effortlessly.
  4. Outlined seamless integration with existing platforms like e-RaktKosh and Blood Bridge, ensuring real-world adoption and scalability.

What we learned

  1. Blood donation is as much a behavioral challenge as it is a technological one — retention and emotional motivation matter deeply.
  2. Donor fatigue and inconsistency are major hurdles — gamified incentives and personalized AI nudges can drive recurring participation.
  3. Language inclusivity and empathy-driven design are essential to build trust with low-tech and rural communities.
  4. Government systems are foundational, but innovation must layer on top to make blood networks smarter, faster, and more life-saving.

What's next for RaktaFlow

  1. Pilot Deployment with a local NGO or hospital to validate the platform’s impact in a live setting.
  2. Expand language support and test chatbot conversations with diverse regional users across India.
  3. Train and refine the AI model with anonymized donor history to improve predictive accuracy and donor engagement.
  4. Develop secure APIs for real-time integration with platforms like e-RaktKosh and Blood Bridge.
  5. Strengthen data privacy and compliance, ensuring consent, encryption, and transparency at all levels.
  6. Launch awareness campaigns, including WhatsApp-based outreach, to promote early diagnosis and donor participation in Thalassemia care.
