An improved sprayer assembly for delivery of physiologic glue, including fibrin glue, is disclosed. The sprayer assembly is comprised of at least one female receptacle rigidly affixed to a base member and a sprayer member having at least one atomizing ejection port on an external surface opposing the base member. Within the sprayer member, a system of fluid channels permits each reservoir to be emptied into a well from angular connecting channels, which causes enhanced turbulence within each well. A vortex is created which propagates through an exit port and down an exit channel, causing each solution to exit the sprayer member at each ejection port in a swirling pattern. The spray patterns emitted from each syringe or reservoir overlap, causing droplets of solution to contact one another and commence a clotting reaction at a wound surface. The sprayer assembly is joined to a conventional syringe, a catheter or other solution reservoir. Thus, quickly reacting substances are stored apart from one another and only come into contact while airborne. The positioning of the ejection ports is selected to prevent droplets exiting one port from contaminating the contents within the neighboring port and channel. Thus, propagation of the reaction within the device, and subsequent plugging of the assembly is avoided.
