The reliability of critical manufacturing equipment in pharmaceutical and medical device facilities is not merely an operational concern it is a patient safety imperative. Unplanned equipment failures in sterile drug manufacturing can trigger product recalls, compromise supply chain continuity, and attract regulatory enforcement action. Despite significant advances in predictive maintenance (PdM) technology across other industrial sectors, its systematic adoption in healthcare manufacturing has been constrained by unique regulatory, operational, and data-availability challenges.This white paper presents a conceptual framework for AI-enabled predictive diagnostics tailored to the specific demands of healthcare manufacturing environments. The framework integrates multi-modal sensor fusion, a hybrid deep learning architecture combining Convolutional Neural Networks (CNN), Long Short-Term Memory networks (LSTM), and Transformer-based attention mechanisms, with an explainable AI (XAI) layer and a regulatory compliance module designed for alignment with FDA 21 CFR Part 11, ISO 13485, and EU GMP Annex 11 requirements.This paper is intended to articulate the technical rationale, architectural design, and implementation considerations for such a system, drawing on established literature in predictive maintenance, deep learning, and pharmaceutical quality management. It is aimed at biomedical engineers, quality assurance professionals, manufacturing technology leaders, and regulatory affairs specialists evaluating the adoption of AI-driven maintenance strategies.
