Resumen de: WO2026074549A1

This invention, titled "Medical Identification and Signal Tag System", addresses the growing challenge of maintaining accurate and timely patient monitoring in high-stress clinical environments such as emergency rooms and operating theaters. The technical problem targeted by this invention stems from the overwhelming workload, fragmented patient data systems, and delayed response times that often lead to medical errors and professional burnout among healthcare workers. To overcome these limitations, the invention integrates an Advanced Monitoring Analytics Module with a Wearable Medical Identification Tag. The system automatically analyzes patients' vital signs using artificial intelligence and machine learning algorithms capable of detecting critical physiological changes in real time. These algorithms dynamically interpret multi-parameter inputs such as heart rate, blood pressure, oxygen saturation, and body temperature and issue immediate alerts to the medical staff through a secure wireless connection. Technically, the invention employs a dual-component architecture. The monitoring unit, attached to the hospital's existing patient monitor, collects and processes biosignals using a high-speed microcontroller and a neural processing unit (NPU). The second component, the wearable tag, communicates via BLE protocol and provides visual, vibrational, and digital alerts through LED indicators and an integrated LCD interface. A secure encryption layer ensures data confidentiality
