Abstract

A connector for joining an endotracheal tube and an integrally formed auxiliary lumen to a source of anesthesia and a preselected item of auxiliary equipment, respectively, includes a first pair of tubular mounting members on a proximal end of the connector that are closely radially spaced with respect to one another and longitudinally spaced from a second pair of tubular mounting members on a distal end of the connector that are closely radially spaced with respect to one another. A pair of parallel bores are formed in the base of the connector to provide fluid communication between associated, longitudinally spaced apart mounting members. The radially spaced mounting members on the proximal end slide-fittingly receive the respective distal ends of an anesthesia supply tube and an auxiliary monitoring equipment tube, and the radially spaced mounting members on the distal end slide-fittingly receive the respective proximal ends of an endotracheal tube and an auxiliary lumen that is formed integrally with the endotracheal tube. The endotracheal tube and lumen share a common length.

A connector, comprising:

a base member of predetermined longitudinal extent having a proximal end and a distal end;
a first tubular projection, having a predetermined diameter, disposed on said proximal end of said base member;
a second tubular projection, having a predetermined diameter, disposed on said proximal end of said base member;
said predetermined diameter of said first tubular projection being substantially greater than the predetermined diameter of said second tubular projection;
said first and second tubular projections being disposed in closely spaced parallel relation to one another;
a third tubular projection, having a predetermined diameter, disposed on said distal end of said base member;
a fourth tubular projection, having a predetermined diameter, disposed on said distal end of said base member;
said predetermined diameter of said third tubular projection being substantially greater than the predetermined diameter of said fourth tubular projection;
said second and fourth tubular projections being disposed in closely spaced parallel relation to one another;
a first bore means formed in said base member for providing fluid communication between said first and third tubular projections;
a second bore means formed in said base member for providing fluid communication between said second and fourth tubular projections;
said first and second bore means being disposed in parallel relation to one another;
said first tubular projection disposed in axial alignment with said third tubular projection;
said second tubular projection disposed in axial alignment with said fourth tubular projection;
an anesthesia supply tube;
an auxiliary tube;
an endotracheal tube;
an auxiliary lumen integrally formed with said endotracheal tube;
said anesthesia supply tube being releasably connected to said first tubular projection and said auxiliary tube being releasably connected to said second tubular projection;
said endotracheal tube being releasably connected to said third tubular projection and said auxiliary lumen being releasably connected to said fourth tubular projection;
whereby a single connector interconnects said anesthesia supply tube to said endotracheal tube and said auxiliary tube to said auxiliary lumen and wherein said anesthesia supply tube, endotracheal tube, auxiliary tube, and auxiliary lumen are substantially free of constrictions.
