Claim:
An improved fluid flow tubing system for use with a handpiece, said handpiece of the type having at least two separate fluid flow paths, said system comprising: means for supplying a first fluid to a first of said fluid flow paths; means for supplying a second fluid to a second of said fluid flow paths; a flexible tube having a proximal end, a distal end and an inside diameter; first and second separate flow lumens, said second lumen formed by a tube wall integral with and formed on an interior surface of said tube; said second lumen having an inside diameter; said first lumen adapted to connect to said first flow path; said second lumen adapted to connect to said second flow path; said first and second lumens disposed within said tube, said first lumen comprising the portion of the interior of said tube not occupied by said second lumen; means for connecting said first and second lumens to said handpiece at said tube proximal end, said connecting means comprising a hollow plug having first and second ends, said first end including a first hollow plug section with a first outside diameter, said first outside diameter being substantially equal to said inside diameter of said tube whereby said tube engages said first plug section in a fluid-tight fit; a connecting tube having first and second ends, said first connecting tube end having an outside diameter substantially equal to said inside diameter of said second lumen, whereby said first connecting tube end engages said second lumen in a fluid-tight fit; said connecting tube extending through said plug; means for attaching said plug to said first of said handpiece flow paths; and means for attaching said connecting means to said second of said handpiece flow paths.
