3D-printed valves to assist noninvasive ventilation procedures during the COVID-19 pandemic: a case study


Keywords: 3D printing • continuous positive airway pressure • COVID-19 • full-face snorkel mask • medical devices • NIV • non-invasive ventilation • selective laser sintering

Aim: To produce valves to be used with full-face snorkeling masks for noninvasive ventilation (NIV) procedure during the coronavirus disease 2019 (COVID-19) pandemic. Materials & methods: ISINNOVA’s Charlotte valves for full-face snorkeling masks used for NIV procedures were redesigned, produced by selective laser sintering additive manufacturing, and submitted to air leakage tests. Results: The final model assembly did not present air leakage during the NIV procedure on human models, minimizing risks of air contamination. Conclusion: This study shows the feasibility of using additive manufactured valves with snorkel facial masks to support health systems during COVID-19 and possible future pandemics.
