MULTI-STAGE MIXING SYRINGE

摘要

A system and method for mixing fluid constituents within a multi-stage mixing syringe, and delivering the mixture formed in the mixing syringe. The multi-stage mixing syringe system includes an outer syringe barrel defining a first contained volume therein, an intermediate syringe barrel and plunger configured for coupling within the outer syringe barrel and for advancement and retraction within the first contained volume, and defining a second contained volume therein, and an inner syringe plunger configured for coupling within the intermediate syringe barrel and plunger and for advancement and retraction within the second contained volume.
