Abstract
A personal respiratory isolation assembly includes a manifold-filter assembly configured to be attached to a suction port of a respiratory pump. The manifold-filter assembly has a bowl-shaped manifold housing with an inlet adapter configured for connecting a hose, and a filter releasably attachable to the manifold housing. The isolation assembly further comprises an exhaust baffle with a plurality of openings. The exhaust baffle fits a pressure port of the respiratory pump. A method of operating a personal respiratory isolation assembly involves attaching an exhaust baffle to an outlet adapter of a respiratory pump; connecting a manifold housing to a suction port of the respiratory pump with a filter disposed between the manifold housing and the suction port; connecting a hose to an inlet adapter of the manifold housing; attaching the hose to a hose port of a hood; and starting to operate the respiratory pump.
