Desarrollo de monitor biométrico de signos vitales para asistir al diagnóstico en telemedicina

Abstract

CONDITION FOR PUBLICATION OF PROJECT. The consolidation of telemedicine as a primary care modality demands technological tools that ensure remote diagnostic reliability. This project justifies its relevance by mitigating current clinical uncertainty through the implementation of a biomechatronic device capable of monitoring ECG, SpO2, and temperature, ensuring information integrity via the Internet of Medical Things. During development, a concurrent mechatronic design based on the dual-core ESP32 microcontroller and the FreeRTOS operating system was employed for real-time task management. Biomedical sensors were integrated into an ergonomic PLA structure with a retractable cabling management system, utilizing the MQTT protocol for efficient and secure data transmission. The results validated the system's capacity to simultaneously acquire and transmit physiological signals without interference, achieving a functional, compact, and economically profitable prototype under a B2B production model. Finally, it is concluded that the proposed solution optimizes the telemedical workflow by providing objective real-time data, overcoming the limitations of visual inspection and manual vital sign recording.
