Wound sealant preparation and application device and method
First Claim
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; and
a 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.

Abstract
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.

14. A device for mixing a plurality of fluids and applying the resultant mixture, said device comprising:
-
a manifold comprising; an inlet end and an outlet end opposite said inlet end; first and second inlets located in said inlet end and first and second outlets located in said outlet end; first and second fluid channels extending from said first and second inlets to said first and second outlets, respectively; and a gas channel extending from a third inlet in said inlet end 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; a one way valve positioned in said gas channel; first and second fluid inlet fittings on the inlet end of the manifold positioned at the first and second fluid channel inlets, respectively, said first and second fluid inlet fittings adapted to removably connect to first and second syringes, respectively; first and second syringes removably connected to said first and second inlet fittings, respectively so that said first syringe is capable of providing a first fluid to said first fluid channel, and said second syringe is capable of providing a second fluid to said second fluid channel; a mixing chamber positioned on the outlet end of said manifold so that fluid streams exiting said first and second fluid channels are deflected by opposing regions of the mixing chamber; and a delivery spout for delivering fluids from the mixing chamber to a target.

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. - View Dependent Claims (16, 17, 18, 19, 20)
