1. A protective barrier system for preventing spread of infectious aerosols, generated by or around a patient, into a surrounding environment when the patient is in a supine position and is being treated by a healthcare worker with a patient interface device, the system comprising:
a flexible, fluid-impervious sheet having preset longitudinal and transverse dimensions and adapted to cover at least an upper torso of the patient;
the sheet having a face portion which is adapted to cover at least a face of the patient,
the face portion having an aperture which is adapted and dimensioned to, overlie at least a nose and mouth area of the patient,
a plate adaptor made of a pliant non-porous material, mountable on the sheet to encircle the aperture, the plate adaptor comprising a corresponding adaptor aperture to form a passageway through the sheet, adaptor aperture being dimensioned to operatively couple to and form a snug engagement with the section of the interface device without gapping regardless of the size of the section of the interface device,
wherein the plate adaptor includes an upper flange and a lower flange, the flanges configured to support the sheet therebetween and encircle the aperture on opposite sides of the sheet;
wherein, in use, when the sheet is positioned over and on the patient with the sheet covering at least the patient's upper torso including the face portion covering at least the patient's face and the aperture overlying at least the patient's nose and mouth area, the plate adaptor is mounted on the sheet to encircle the aperture, and the section of the interface device is positioned through the adaptor aperture, said adaptor aperture being dimensioned to form a snug engagement with the section of the interface device without gapping regardless of the size of the section of the interface device to block the infectious aerosols generated by or around the patient so as to prevent escape of the infectious aerosols into the surrounding environment and consequent contamination of the healthcare worker thereby forming a protective barrier between the patient and the healthcare worker.
