In embodiments of the present invention, a suction cleaning system component is provided for use in cleaning an interior of a tracheal ventilation tube when the suction cleaning system component is connected to the tracheal ventilation tube and a ventilator. Typically, the suction cleaning system component is used in a closed endotracheal suction system environment. The suction cleaning system component comprises a cleaning catheter and a manifold. The manifold comprises an obstruction element, which is moveable with respect to (i) the ventilator port and (ii) the expandable element. The obstruction element is configured to assume a plurality of states, including an obstruction state.
