 The Covid Isolation Box is a folded clear plastic enclosure designed to protect practitioners from sputum and other bodily fluids emitted by covid-19 patients. The design is lightweight and disposable, and can be stacked at pre-staging locations around an emergency department for quick deployment. The box is roughly 22" tall, 24" wide, and 20" deep when deployed, providing plenty of room around the patient's head and upper torso for intubation and other procedures (note that the first image below is an earlier iteration with less headroom). On-site assembly takes less than five minutes, and the box uses ~$15 in materials for construction.

-The Covid Isolation Box is currently undergoing IRB-approved trials at Boston Medical Center with 35 commercially sourced units. Feedback from medical professionals involved in this trial will feed in to future design iterations.

+The machine-made creases are quite accurate but need to be re-folded so the box is square and sturdy after assembly. All of the re-fold operations happen the same direction (i.e., they are all "mountain folds" when viewed from outside the assembled box). Perform these operations by carefully closing the folds between your thumb and forefinger and tightly squeezing the plastic together, as if you were folding a piece of paper or card stock. First, re-fold all of the straight green lines other than those marked with an "X":
