A unitized ventilating system with front, side, and rear swivel connections and a sealed suction catheter assembly permitting continuous ventilation of a patient and combined suctioning ability. The entry ports to the assembly are normally valved closed to prevent the escape of vitally needed ventilating gases to atmosphere when the system is attached to the ventilator. The catheter is housed in a pre-formed collapsible protective envelope subassembly with attached couplings for convenient inexpensive manufacturing assembly. The entire system is designed for patient safety, healthcare worker protection from infectious diseases, simplified manufacturing, reduced cost, and completely disposable after twenty-four hours of continuous use.
