Amid the COVID-19 crisis, healthcare workers around the globe are running out of PPE, leaving themselves at risk of contracting coronavirus. Working with a local hospital, I've designed an adapter that allows them to use their older 3M BE-10L PAPR (Powered Air-Purifying Respirator) hoods with their newer 3M VersaFlo PAPR respirators. Unlike N95 masks, PAPR units are reusable and give their users complete protection from airborne liquids and particulates. Many hospitals in the United States may have these and other similar systems stockpiled from the 2014 Ebola epidemic and with this design, may be able to reuse them to protect doctors and nurses. As usual, please make sure to reach out and ask before taking any action.
