The present invention provides a preparation and application device useful for mixing and dispensing a plurality of fluids, wherein the fluids must be mixed immediately prior to use. In one embodiment, the device includes two fluid delivery systems connected to a manifold having two separate fluid channels. Each fluid channel conducts fluid to a mixing chamber, from which, following mixing, the mixture of fluids is dispensed. The manifold additionally includes a gas channel having an outlet connected to one of the fluid channels, which can be used to supply a pressurized gas to the mixing chamber to expel the mixture from the chamber, reducing the likelihood that the mixture can clog the device. The invention also provides a method for preparing and dispensing a mixture of two fluids.

[ What is claimed is:] [1.] A device for mixing a plurality of fluids and applying the resultant mixture, said device including a manifold comprising:an inlet end having first and second inlets and an outlet end opposite said inlet end having first and second outlets;first and second fluid channels

[ What is claimed is:] [1.] A device for mixing a plurality of fluids and applying the resultant mixture, said device including a manifold comprising:an inlet end having first and second inlets and an outlet end opposite said inlet end having first and second outlets;first and second fluid channels extending from said first and second inlets to said first and second outlets, respectively; anda gas channel extending from a third inlet and terminating at an outlet wherein said outlet is continuous with a wall of said first fluid channel wherein said gas channel does not extend to the outlet end of said manifold. [15.] A method for preparing and dispensing a mixture of a plurality of biological fluids comprising:(a) admixing a first biological fluid with a pressurized gas to form a first biological fluid-gas mixture;(b) vigorously mixing said first biological fluid-gas mixture with a second biological fluid in a mixing chamber to form a second biological fluid-gas mixture, wherein the second biological fluid-gas mixture develops a viscosity greater than the first biological fluid-gas mixture; and(c) ejecting a stream of said second biological fluid-gas mixture through an opening of said mixing chamber before said second biological fluid-gas mixture can plug the opening. The method of claim 15 additionally comprising, after dispensing a desired amount of said second biological fluid-gas mixture, purging said mixing chamber of said second biological fluid-gas mixture by flowing pressurized gas through said mixing chamber. The method of claim 16 additionally comprising, after purging said mixing chamber, repeating operations (a)-(c) of claim 15. The method of claim 15 wherein said pressurized gas is a sterile medical gas. The method of claim 18 wherein said first biological fluid includes fibrinogen and said second biological fluid includes a fibrinogen activator.
