A closed ventilating/drainage system for involuntary respiration of a medical patient comprising: ventilating tubing comprising fluid flow passageway means by which influent and effluent ventilating gas is delivered to and received from a medical patient whereby liquid accumulates in the tubing; liquid drainage means disposed at a low point along the tubing in fluid communication with the fluid flow passageway means, the drainage means comprising hollow fluid flow path means along which ventilating gas and liquid accumulated in the tubing respectively pass, the drainage means further comprising a fluid-tight internally hollow liquid storage container means closed to the atmosphere and contamination therefrom, said container means being disposed below the fluid flow path means and non-gravity hollow drainage means closed to the atmosphere and contamination therefrom, the interior of which is interposed in fluid communication with the hollow of the liquid storage container means and normally-closed manually operated suction means whereby liquid passing along the fluid flow path means drains by force of gravity into the hollow of the liquid storage container means and is selectively evacuated from the container means via the hollow drainage means and the suction means without removal of the container means from the system and without termination of ventilation, said hollow drainage means further comprising a normally-closed vacuum probe-receiving valve means and at least one openable valve site and wherein the suction means comprises a vacuum probe which is manually inserted into the valve means to open the valve site and by which negative pressure provided by the probe is selectively communicated to the hollow interior of the liquid storage container means across the open valve site to evacuate liquid stored in the container means through the manually inserted probe.
