Closed ventilation and suction catheter system

A catheter assembly for the irrigation and suctioning of the lungs of a patient, said catheter assembly comprising;

• a catheter including an elongated tubular member having a plurality of lumens extending therethrough, said tubular member having proximal and distal ends thereon;
• a valve assembly having a plurality of valve members therein wherein said valve assembly is operatively associated with said proximal end of said catheter and in operative flow communication with said lumens of said catheter to selectively enable and disable the irrigation and suctioning of the lungs of the patient through said lumens of said catheter;
• adaptor means operatively associated with said catheter to enable said distal end of said catheter to be inserted into the lungs of the patient therethrough;
• said distal end of said catheter including at least one opening from one of said lumens adjacent thereto to enable communication with the lungs of the patient through said catheter;
• and
• envelope means operatively associated with said valve assembly and said adaptor means for selectively sealing said catheter from exposure to the atmosphere;
• wherein said valve assembly further including a first valve member movable between an open and a closed position to operatively control the flow of irrigation fluid through one of said lumens in said catheter and a second valve member movable independently of said first valve member between an open and a closed position to operatively control the flow of suction pressure through another of said lumens in said catheter, said first valve member movable independently of said second valve member;
• and
• means for reversible mountings on said valve assembly in association with said first and second valve members to selectively lock said first and second valve members in either said open position or said closed position concurrently, wherein said reversible mounting means is a cover.
