Abstract

See full text

In some examples, a mixing syringe includes a fluid housing defining an internal housing chamber for storing a medical agent, and a fluid outlet. An outer plunger is disposed within the internal housing chamber of the fluid housing. The outer plunger includes an outer barrel defining a barrel cavity and an outer plunger head connected to the outer barrel. The outer plunger is adapted for longitudinal movement within the internal housing chamber of the fluid housing. The outer plunger head defines a flow passage whereby, upon movement of the outer plunger the medical agent passes from the internal housing chamber through the flow passage into the barrel cavity of the outer plunger. An inner plunger is adapted for longitudinal movement relative to the outer plunger to force the medical agent through the flow passage of the outer plunger head for disposition through the fluid outlet of the fluid housing.
