Abstract
An applicator for mixing and applying multi-component compositions to a work surface, such as two-component surgical sealants, while avoiding clogs, preventing cross-contamination of the components until a point of intended mixing at a location within the apparatus immediately upstream of an application opening in a tip cap, decreasing pressure drop along the applicator to facilitate fluid delivery, and increasing efficiency of mixing of the components. A luer hub sub-assembly having a proximal hub and a distal hub, an elongate, four-lumened cannula, and a spray tip sub-assembly are provided, with interconnections between the sub-assemblies preserving isolation of the fluid components from one another. The tip cap sub-assembly includes registration structure to assure proper alignment between tip cap and tip insert. The end wall of the tip cap includes a spinner region with three feeders leading thereto, the fluid components remaining isolated from one another in two of the feeders, and initiating mixing with one another in a third of the feeders.
