Abstract
A ventilation contamination control device for use on the expiratory line of a ventilator unit. The device couples to a contained vacuum source to provide a closed system that does not require the continuous, direct filtration of exhalation from the patient. The device includes a housing on which a flexible exhalation containment bag and a unidirectional check valve are mounted. The check valve permits inward atmospheric air flow during low exhalation periods but prevents outward contaiminated air flow. A bacteria filter unit is mounted on the housing to provide a filtered vent to the atmosphere in the event that the vacuum source or the check valve become obstructed or fail. An audible signal responds to such a failed condition.
