AI-Powered Automated Visual Inspection of IV Bags: A Real-World Case Study
A high-volume IV bag line with variable printing faced ongoing false rejects, prompting deployment of an AI-powered automated visual inspection (AVI) system from concept to production floor. The AVI system learns to distinguish subtle print artifacts from true particulates in real time, preserving print legibility while reducing misclassifications caused by printing variability, bag deformation, and lighting. The program progressed from concept through design, proof-of-concept testing, scale-up, FAT, SAT, and production qualification and validation. The AVI architecture blends deep learning defect detection with high-quality image capture and integrates with existing MES/packaging controls to gate good product and flag anomalies without slowing throughput. Practical design questions were addressed: camera placement, illumination strategies, data management and labeling, and model training and validation. Regulatory alignment (IQ/OQ/PQ, change control, GMP) underpins lifecycle management for AI-enabled inspection, including retraining and performance monitoring. Real-world learnings cover key design choices, maintenance strategies, and deployment milestones to sustain performance in continuous production. Expected outcomes include lower false rejects, improved detection of particulates on challenging flexible bag formats, and enhanced line efficiency while maintaining compliance.
