"The motivation for creating a respirator is given by the socioeconomic and health crisis caused by the COVID-19 pandemic.
The design consists of a mechanism, comprised of a spur gear speed reducer and a connecting rod-crank system that compresses a manual resuscitator.
Currently, given that owning a 3D printer is common among individuals, a polymer was applied to allow them to manufacture the design from their own homes. This provides a quick and inexpensive response to the shortage of respirators in hospitals.
To verify that the model had the correct dimensions and a suitable material, an analysis was applied with the SimSolid software where, among other aspects, it was possible to see which part of the mechanism is more susceptible to wear and tear over time.
A characteristic of this software is that it does not use a mesh with nodes to solve the model and therefore it is not necessary to define elements nor the size of the mesh, but rather uses a methodology based on functions in such a way that the response time before the calculation is practically immediate.
This project was presented to the Contest Premios Trabajo Fin de Máster of the Colegio Oficial de Ingenieros Industriales de Madrid and the Fundación Rodolfo Benito Samaniego in collaboration with the Asociación de Ingenieros Industriales de Madrid.
The project tutor, Alejandro Palacios Madrid, and I received an Honorable Mention from the AIIM and the Fundación Rodolfo Benito Samaniego.
