SYRINGE WITH PRIMING MECHANISM

Abstract: syringes are described herein. a syringe includes a syringe body, a first plunger, a biasing member, and a retention member. the syringe body defines a syringe cavity and a syringe port, wherein the syringe port is in fluid communication with the syringe cavity. the first plunger comprises a first plunger shaft extending from the first plunger, the first plunger disposed within the syringe cavity and defining a first chamber in the syringe cavity, wherein the first chamber is in fluid communication with the syringe port. the biasing member is coupled to the first plunger shaft, wherein the biasing member urges the first plunger to advance toward the syringe port. the retention mechanism prevents the biasing member from advancing the first plunger in an engaged position and permits the biasing member to advance the first plunger in a released position.
