Objectif : Tester un dispositif qui peut améliorer l’étanchéité des masques respiratoires filtrants (FFR). Méthodes : Un prototype en 3D d’un cadre d’amélioration de l’ajustement (FIF) a été créé et des essais d’ajustement quantitatifs ont été réalisés pour des FFR avec et sans FIF.
Objective: Test a device that can improve upon the seal of filtering face mask respirators (FFRs) Methods: A 3-D prototype for a fit improvement frame (FIF) was created and quantitative fit testing was performed for FFRs with and without the FIF Results: 38 volunteers underwent fit testing. The overall fit pass rate was 100% for the 3 M model 1860 masks, 50% for the 3 M model 1860 masks, 13% for the BYD CARE model DE2322 and 7% for the Honeywell DC300N95. When using the FIF the overall passing rate increase to 87% for the DE2322 + FIF (p < 0.01) and for the DC300N95 + FIF the passing rate increase to 73% (p < 0.01) Conclusion: The FIF is effective in improving the mask fit of a common flat fold N95 masks and potentially other N95 masks.
