This is a design for a vacuum formed face tent with a 3D printed connector.  This is a derivative of the DFab-NRB.  It is meant to apply suction to a covid patient’s face without cutting off the air supply. The patient is expected to be receiving oxygen and may be using high flow nasal cannula.  The goal is to collect the droplets and aerosols from normal breathing. We know it will not collect all of the aerosols when coughing. 

Our design includes:

1. A vacuum formed plastic mask

2. A 3D printed connector to vacuum

We do not include a suction canisters or tubing which should be supplied by the hospital for connecting the device 

We have designed the buck to be made as either a milled or 3D printed. We included both a forming buck and a cutting buck. We have used both PETG and polystyrene as our vacuum forming material. We recommend using a Formtech vacuum former, or any other top loading vacuum former. Book style vacuum formers will not work. We have used both 0.03” and 0.06” sheets to make the vacuum formed buck. The concept is scalable for maks manufacturing using die cutters and industrial vacuum formers

Our designs are uploaded as Solidworks 2019, STEP and STL files.
