Abstract
A mixing and dispensing disposable medicament injector having a cylindrical barrel closed at one end by a slidable plunger and at the other end by a first diaphragm assembly including a flexible wall. A second diaphragm assembly is positioned within the barrel intermediate the ends thereof to divide the barrel into two sealed chambers, a first chamber between the plunger and second diaphragm assembly being adapted to contain a liquid and a second chamber between the second diaphragm assembly and the first diaphragm assembly being adapted to contain a medicament in dry form. The second diaphragm assembly has a rupturable flexible wall to allow liquid to flow into the second chamber and the flexible wall in the first diaphragm assembly being rupturable to allow the mixed liquid medicament to be dispersed from the injector through the cannula fluidly connected to the first diaphragm assembly.
