Building a Personal Medical Records RAG Pipeline with Qdrant and Local Embeddings
Original: Quantified Self 2.0: Stop Guessing Your Health History—Build a Personal Medical Vector Database
Short summary
This tutorial walks through building a personal health knowledge base using a RAG pipeline with Qdrant, Unstructured.io, and Sentence-Transformers. It covers parsing messy medical PDFs (lab results, scans, EMRs) into embeddings, storing them in a local vector database, and querying semantically across years of records. The pipeline uses local models to keep sensitive health data private, with a FastAPI interface for retrieval and LLM synthesis.
- •RAG pipeline turns 10 years of scattered medical records into a searchable vector database
- •Unstructured.io handles complex medical PDF parsing with layout-aware OCR
- •Local embeddings via Sentence-Transformers keep sensitive health data private
Generated with AI, which can make mistakes.
