ABSTRACT:
A closed ventilation and suction catheter system for aspirating or suctioning the bronchial tree or trachea of a patient including a dual lumen catheter, the proximal end of the catheter is connected to a dual valve assembly which is connected to separate irrigation fluid and suction pressure sources and the distal end of the catheter is adapted to be slidably positioned in communication with the bronchial tree of a patient. A transparent and flexible envelope surrounds the catheter to protect the catheter from direct exposure to the atmosphere. The catheter is slidable from the inside of the envelope through an adaptor and a tracheal tube to communicate with the bronchial tree or trachea of the patient. A ventilator is connected to the adaptor near the distal end of the catheter to provide for the artificial ventilation of the patient. The bronchial tree or trachea of the patient may be irrigated and aspirated through the dual lumen catheter and the catheter may be substantially withdrawn into the envelope so that the distal end of the catheter system may be substantially positioned in an irrigation chamber in the adaptor so that the outer surface of the catheter may be flushed with irrigation fluid to remove any mucous accumulated on the distal end thereof.
