Abstract
A movable mixing disc may be utilized in connection with a syringe. The mixing disc may comprise a hole which may be covered by a fine screen or coupled to a porous member, allowing only certain elements of a solution to pass through the mixing disc. Actuation of a plunger of the syringe may cause liquid to emerge from the mixing disc hole as a high velocity jet or other turbulent flow, stirring up any settled particles on a distal side of the mixing disc. As the ejection continues, the mixing disc may be pushed forward by the plunger in order to eliminate any unused volume. Also, the mixing disc may be moved forward by virtue of a pressure difference created by a pressure drop across the mixing disc, such as a pressure drop created as the plunger is displaced to induce fluid flow across the mixing disc.
