MANUAL VENTILATION SYSTEM INCLUDING MANUAL BAG FILLING VALVE

摘要

An open ventilation system (10) for intensified breathing that includes both a manual ventilation system(16) and an automatic ventilation (14) system. A ventilation selection switch (68) is positioned in the system prior to the patient circuit to select between the manual and automatic ventilation systems (16,14). The manual ventilation system (16) includes a manual bag filling valve (96) that controls the flow of inhalation gases (96) from the ventilation selection switch (68) to a manual bag (20). The manual bag filling valve (96) includes a valve assembly that is movable between an open position and a closed position based on the difference in the forces created by the pressures of the manual bag (20) and the inhalation gas.
