Abstract: A portable protective hood for use during medical procedures to avoid the spreading of aerosolized patient discharges. The protective hood includes an easy to assembly frame having a base plate formed with mounting sockets that can receive the remote ends of plastic ribs that will arch over the base plate. A transparent plastic bag has an elastomeric opening that enables the plastic bag to be placed over the upright ribs and extend down to the base plate. The base plate is shaped to incorporate curved sections that allow the movement of air from the atmosphere into the plastic bag, which is extracted through a connector on the plastic bag for attachment to a vacuum extraction device. The base plate and ribs are formed from a non-porous plastic material that permits cleaning between uses. The base plate and ribs can be placed into a storage configuration when not in operative use.
