Abstract: Various implementations include a mixing vial for use in a cartridge syringe. The mixing vial includes a vessel, a stopper, and a dislodgeable plug. The stopper includes an open first end, a closed second end, and a stopper side wall. A hollow interior chamber is defined by the stopper side wall and the closed second end. The stopper is positioned in a sealing relationship with an inner surface of the vessel. An outer surface of the stopper side wall includes two ribs extending radially outwardly from the stopper side wall. Each of the two ribs is axially spaced apart from each other. An inner surface of the stopper side wall defines an annular groove located axially between the two ribs. The dislodgeable plug is disposed within the hollow interior chamber of the stopper such that an edge of the dislodgeable plug is disposed within the groove of the stopper.

Abstract: Various implementations include a mixing vial system. The system includes a hypodermic syringe and a mixing vial. The mixing vial includes a vessel, a stopper, and a dislodgeable plug. The vessel includes an open end, a closed end, and a side wall. A hollow interior chamber is defined by the side wall and the closed end. The open end defines a neck. The stopper includes an open proximal end, a closed distal end, and a stopper side wall. The closed distal end and the stopper side wall define a hollow interior chamber. The stopper is positioned in a sealing relationship within the neck. The dislodgeable plug is positioned in and sealing the open proximal end of the stopper. The closed distal end of the stopper is penetrable by a needle of the hypodermic syringe to dislodge the dislodgeable plug to effect mixing of contents of the stopper and the vessel.

Abstract: A mixing vial having a hollow interior chamber with a tubular portion having distal and proximal open ends and a stopper positioned in sealing relationship in the tubular portion, the stopper having a hollow interior chamber with an open end and a dislodgeable plug positioned in and sealing the open end.
