Abstract
A movable mixing disc is inserted into a regular syringe. The mixing disc has a small hole covered by a fine screen, allowing only saline solution to get behind the disc. When the plunger of the syringe is pressed, the saline solution emerges from the mixing disc hole as a high velocity jet, stirring up the settled particles. As the ejection continues, the mixing disc is pushed forward by the plunger in order to eliminate any unused volume.
