摘要： The invention encompasses devices and methods that at least partially entrap the droplets and aerosols from a person undergoing an aerosol/droplet-generating procedure, thereby reducing a heath care worker's direct exposure to such health hazards. The device includes a planar cover structure impermeable to aerosols, droplets, fluids and gas. The planar cover structure providing a barrier between a health care worker and the body cavity or orifice of a patient. A hollow tubular extension forming an opening on the planar cover structure and the opening is configured to he positioned approximately on top of the body cavity or orifice of the patient. The opening configured to be reversibly closed via a closure mechanism.
