Abstract
The pandemic caused by the coronavirus (SARS-CoV-2), which causes the disease COVID-19, forced health authorities and research institutes to propose solutions. An important and accessible tool to fight against the virus the use of masks. The VESTA respirator's designed product is the new antiviral N95 filtering facepiece respirator developed by the researcher team from the University of Brasilia. The VESTA differential is the chitosan nanofilm, present in the intermediate layer, that works as a physical barrier for the virus. The nanofilm has antimicrobial action and greater ability to filter viruses, including the SARS-CoV-2 that causes COVID-19. The respirator consists of a semi facial piece composed of filtering material covering the nose, mouth and chin. It is fixed on the face by two elastics headband and a nasal clip to reinforce the face's sealing. This paper analyses the VESTA nasal clip structural characteristic as tension, deformation, and vibration. This device is responsible for securing the sealing around the user's nose. The nose clip improves the protection of leakage between the respirator and the face. Numerical simulation of the nasal clip structural analysis was performed using ANSYS.
