Abstract:
1. An apparatus for delivering a mixture of at least two fluid components in a manner that prevents premature cross-contamination of the fluid components, comprising: a luer hub sub-assembly, including a malleable cannula having a proximal end region received in the cylindrical female cannula-mating port, the malleable cannula including first and second fluid-carrying lumens, each of the first and second fluid-carrying lumens being in fluid communication with a respective one of the fluid path holes, a third lumen having a wire disposed therein, and a fourth lumen; and a spray tip sub-assembly including a tip insert received in a tip cap, the tip cap having an end wall with a delivery opening therethrough, wherein a distal end region of the malleable cannula includes a pair of notches extending from a distal end wall of the malleable cannula to a pair of stop walls axially spaced proximally of the distal end wall, each of the notches exposing a respective semi-cylindrical channel extending from a respective one of the first and second fluid-carrying lumens, and alignment ledges extending laterally from each of the semi-cylindrical channels to an outer perimeter of the malleable cannula.
