Rehabilitación de una termocuna con control automático e IoT para la práctica educativa en enfermería

Abstract

The purpose of this research is to develop an automatic control system for the team belonging to the nursing career of the Salesiana University, which allows the automatic control of the main variables and their remote monitoring incorporating IoT technologies; allowing students a better learning experience. For this, first of all, the equipment was reviewed, and neonatology specialists were interviewed, determining that the equipment was an old model of incubator and not a thermo cradle. Subsequently, through the compilation and analysis of specialized literature and technical documentation, the principles of operation and control of neonatal incubators were studied. To adapt the equipment to the needs of the users, CAD software was used as a planner and viewer of the modifications necessary for the integration of a sensory system and specialized hardware. Together, we worked on a remote monitoring and control system, implementing the Node-RED visual programming IoT tool, which allows remote supervision and control of the critical variables of the incubator. Furthermore, to ensure stable and controlled operation of the equipment, an automatic ON/OFF control system was designed, which is used to close the process when the determined temperature is reached. The methodology applied for the development of the project consisted of: the initial diagnosis of the team; the design and planning of Hardware and Software; the implementation of programs and electronic components; and tests and simulation sessions were carried out. Finally, to verify the adequacy and validate the functionality of the system, its performance was evaluated through practical training sessions with students and teachers of the course, and a user manual was developed to ensure the correct use and maintenance of the system. This project successfully met the stated objectives, providing a comprehensive rehabilitation of the incubator's functions and modernizing it by incorporating the remote monitoring and control function in real time through a web interface with an automatic system. These new functionalities allow students to practice in a simulated environment, improving their preparation and professional skills.
