摘要：
Systems and methods for multi-chambered syringes are described. In some embodiments, a multi-chamber syringe includes a housing with an internal cavity and first and second plungers disposed at least partially within the internal cavity. The first and second plungers are slidably displaceable relative to the housing, and are associated with first and second chambers respectively. A barrier is disposed at least partially between the first and second plungers to form the first and second chambers. The barrier is slidably displaceable relative to the plungers and barrel to selectively place the first and second chambers including first and second materials respectively in fluid communication. When the barrier is displaced, the first and second materials mix in a combined volume of the first and second chambers. Displacing the first plunger, the second plunger, and the barrier may dispense the mixed materials from the combined volume.
