Retrofit da Máquina de Circulação Extracorpórea com dispositivo IoMT

Abstract

The evolution of disruptive technologies in the medical field takes significant proportions in the transformation of the sector. The term IoMT (Internet Of Medical Things) defines how this transformation expands and brings performance benefits, maximizing the interaction between machines and people. In this context, the present work improves an extracorporeal circulation machine through the application of IoMT technologies, improving the procedures for monitoring and controlling the operation of the set with the implementation of an estimator of pump pressure and flow. In the development of the project, it was possible to implement a mobile application that communicates with the microcontrolled plate to control the machine's motor, as well as an interpolation estimator to calculate and approximate the pump values. The development were made in stages with modular functional tests and considerable improvements in the calculation of values were identified through comparisons between the environment simulation performed on Proteus and the previous machine program, such as the comparison with the study elaborated on the thesis that inspired this work. Finally, the function test was verified, integrating all the functional parts of the machine in a simulated environment and, thus, validating the remote operation improvement of the machine proposed in this project. The legacy left here allows this study to serve as a framework for future work, in the implementation and expansion of this project with the construction of modern controls, improvements of the mobile application and the elaboration of an electronic plate suitable for the machine.
