In response to COVID-19 PPE needs, Formlabs user Luiz Maracaja and colleagues at Yale School of Medicine devised a novel face shield frame called Oxyframe. The Frame has an air channel system that allows inflow of oxygen or compressed air behind the ear and outflow above the nose-bridge. A standard transparency sheet can be used as a protective face shield. This system enables users to breathe comfortably inside a full hood, while simultaneously defogging the face shield film.
A peer-reviewed paper on this technology was recently accepted to Journal of Cardiothoracic and Vascular Anesthesia
The face shield STL and .form files are available on the Formlabs Pinshape library. https://bit.ly/3eo3bwS
