ABSTRACT:
A respiration hood assembly is effected from a thin-walled headpiece nested within the periphery of a mating exterior housing that includes a filtered aperture. The nested engagement between the headpiece and the housing is also useful in capturing one edge of a plastic membrane skirt that is thus suspended to drape over the person wearing the headpiece. A battery powered electric fan is deployed within the housing to draw ambient air through the vent aperture into the space shrouded by the skirt. The nested headpiece arrangement is useful in retaining other fibrous towels or tissue to extend the usefulness of the assembly and a parallel connection is provided to a motor vehicle battery to extend the period of electrical excitation.
