Point-of-care diagnostics, artificial intelligence in medicine, closed-loop therapy, sepsis detection, Raman spectroscopy, microfluidics. 1. Introduction The "golden hour" of emergency medicine—the critical 60 minutes following traumatic injury or acute illness—demands interventions that are both rapid and precise. Yet, current workflows remain fragmented: blood draws are sent to central labs (turnaround 45–120 min), imaging requires bulky equipment, and infusions are manually titrated by overburdened staff. In low- and middle-income countries (LMICs), the situation is more acute, with a severe shortage of laboratory infrastructure and specialists. This work was funded by the Global Health

The increasing demand for rapid, accurate, and decentralized medical care has spurred the development of point-of-care (POC) devices. However, most existing systems are siloed—diagnostic devices do not communicate directly with therapeutic ones, and data integration remains a bottleneck. This paper introduces the Medima P300 , a compact, portable, multi-modal platform designed to bridge this gap. The P300 integrates (1) a 12-lead ECG and continuous vital signs monitor, (2) a laser-based flow cytometry module for complete blood counts and inflammatory markers, (3) a surface-enhanced Raman spectroscopy (SERS) chip for pathogen and biomarker identification, and (4) a microfluidic closed-loop drug delivery system. Powered by an embedded edge-AI inference engine, the device can diagnose acute coronary syndrome, sepsis, and electrolyte imbalances within 12 minutes from a single fingerstick blood sample and non-contact sensors. In therapeutic mode, the P300 administers pre-filled, algorithm-controlled medication cartridges (e.g., vasopressors, antibiotics, insulin). We present the system architecture, validation data from a pilot study (N=150), and discuss regulatory pathways. The Medima P300 represents a paradigm shift towards autonomous, interoperable POC systems for emergency rooms, ambulances, and low-resource settings. Hartley, PhD; S
