ABSTRACT:
An apparatus for isolating contagious respiratory hospital patients to reduce the nosocomial and airborne transmission of diseases such as tuberculosis, pertussis, influenza and measles is provided. In one embodiment, a self-contained, portable and prefabricated room in combination with an air-flow control and filtering system is provided. The room is adapted to be assembled within the confines of a preexisting structure or room such as a hospital room. The air-flow control and filtering system functions to filter air being exhausted from the room to adjoining patient areas and to maintain the room at a continuous negative air pressure relative to ambient atmospheric pressure. The system also automatically increases its capacity when the door is opened in order to maintain a constant negative pressure and further provides a warning system for monitoring unauthorized access to or exit from the room as well as notification of loss of power and/or operation. In another embodiment, a blower unit including an ultraviolet light and HEPA filter is provided which functions to collect, trap and kill pathogens.
