Smart Dock for POCT Reader
End-to-end product ownership of a point-of-care diagnostic device
Overview
End-to-end product ownership of a Point-of-Care diagnostic device at Aptitude Medical Systems — spanning hardware specification, UX design, and microservices architecture deployed across a Raspberry Pi fleet of 100+ devices.
Product Scope
This project covers the full vertical of a medical diagnostic station: from the physical dock that holds and communicates with test readers, to the software stack that processes results and pushes them to clinical systems.
Architecture
Each station runs 16 Docker microservices on a Raspberry Pi CM5, managing:
- USB-connected reader communication and state management
- Real-time test data processing pipeline
- Clinical operator interface (touch-optimized React app)
- Fleet management via balenaCloud for OTA updates and remote monitoring
Technical Highlights
- Custom state machine for reader and station lifecycle management
- Comprehensive thermal and power monitoring for fleet reliability
- ESP32-based reader hardware integration
- Designed for 24/7 unattended operation in clinical environments
