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.
