The respirator circuit of which the present invention is a part includes a water cascade for humidification of the air, oxygen enriched air or pure oxygen from a conventional respirator. From the cascade a first conduit tube portion connects to a first branch of a Y fitting, a second branch thereof connects a second conduit tube portion to a spirometer, and the main Y fitting leg connects to a conventional endotracheal tube. The improvement that is the focus of this invention is a secondary suction tube or aspirator which is located in close relation to the lowermost main length of the circuit conduits and a plurality of perforations connect between and along the lengths of the main circuit and suction tubes. The suction tube connects to a wall suction inlet as conventionally provided in hospitals, and serves to continuously remove moisture which condenses on the interior wall of the main circuit tubing, either from the cascade, a nebulizer, when used in the circuit with a tracheotomy patient, or excretions from the patient.

A respirator circuit comprising: first and second conduit tubes, the cross-section of which has opposed planar lower side portions that are angled oppositely downwardly and inwardly toward drainage means connected thereto, said first and second conduit tubes in open connection respectively to first and second branches of a generally Y-shaped conduit tube portion, including a leg portion for open connection to a conventional endotracheal tube; a respirator connected to an end of the first conduit tube through a water cascade to humidify air, oxygen enriched air or pure oxygen passing from the respirator into the first conduit tube; the drainage means disposed at a lowermost point of and extending longitudinally along the bottom portions of the first and second conduit tubes, said drainage means being in fluid communication with said first and second conduit tubes through a plurality of perforations opening into the drainage means from the first and second conduit tubes; and means to dispose of moisture passing through said perforations into the drainage means from the first and second conduit tubes.
