Since the beginning of 2020, the entire world has been affected by Covid-19, which has caused millions of infections and deaths, with older adults being the most affected population. Like many other countries in the world, Ecuador has shown a deficit of supplies to face this threat. Within this context, this article shows a pressure-cycled artificial ventilator alternative constructed with 3D printing material. The procedure includes a structural analysis simulation, the topology optimization of the mechanical structure and the implementation of air pressure control in the artificial lung bag. The results of this research shows that the proposed structural design for the artificial ventilator allows reducing the amount of construction material and therefore the manufacturing time, without affecting the effectiveness of its performance. In addition, analysis of the control system responses evidences that a classical PID controller allows the correct performance of the ventilator pressure control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
