Apparatus and method for a lung isolation tube assembly

A lung isolation tube assembly, said lung isolation tube assembly comprising:

• (a) a switch valve, said switch valve being adapted to be moved between a left lumen position, a right lumen position, and a both lumens position and said switch valve comprising:
• (i) a barrel, said barrel having an airflow inlet, a pair of airflow outlets, a detent and a pair of stops that protrude radially inwardly relative to the barrel;
• (ii) an O-ring;
• (iii) a rotor, said rotor having a pair of blockers, a rotor detent, and a handle, wherein the pair of blockers protrude downwardly away from the rotor;
• (b) a connector, said connector being in fluid communication with the switch valve;
• (c) a tube, said tube being in fluid communication with the connector and comprising:
• (i) a left lumen, said left lumen being in fluid communication with the connector and having a left lumen proximate end opening and a left lumen distal end opening;
• (ii) a right lumen, said right lumen being in fluid communication with the connector and having a right lumen proximate end opening and a right lumen distal end opening;
• (d) a first cuff, said first cuff being disposed around a portion of the right lumen and the left lumen;
• (e) a second cuff, said second cuff being disposed around a portion of the left lumen;
• (f) an airflow source;
• said airflow source being in fluid communication with the switch valve;
• wherein the assembly is adapted to convey airflow or oxygen to a human lung via at least one of the left lumen and the right lumen;
• and wherein the right lumen partially surrounds the left lumen.

A method for isolating a human lung, said method comprising:

• (a) providing a lung isolation tube assembly, said lung isolation tube assembly comprising:
• (1) a control valve, said control valve being adapted to be moved between a left lumen position, a right lumen position, and a both lumens position, said control valve comprising;
• (i) a blocker protruding downwardly away from a rotor, said blocker being adapted to rotate radially relative to a barrel;
• (ii) a stop protruding radially inwardly relative to the barrel;
• (2) a connector, said connector being in fluid communication with the control valve;
• (3) a tube, said tube being in fluid communication with the connector and comprising:
• (i) a left lumen, said left lumen being in fluid communication with the connector and having a left lumen proximate end opening and a left lumen distal end opening;
• (ii) a right lumen, said right lumen being in fluid communication with the connector and having a right lumen proximate end opening and a right lumen distal end opening;
• (4) a first cuff, said first cuff being disposed around a portion of the right lumen and the left lumen;
• (5) a second cuff, said second cuff being disposed around a portion of the left lumen;
• wherein the assembly is adapted to convey airflow or oxygen to a human lung via at least one of the left lumen and the right lumen;
• and wherein the assembly comprises a single in port and a pair of out ports;
• and wherein the assembly is adapted to isolate a single lung;
• (b) inserting the tube into a human;
• and,
• (c) supplying airflow or oxygen to the lung isolation tube assembly.
