Abstract
Syringes are described herein. A syringe includes a syringe body, a first plunger, a biasing member, and a priming indicator. The syringe body defines a syringe cavity, a syringe port, and an indicator window, 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 couples to the first plunger shaft, wherein the biasing member urges the first plunger from an unprimed position to a primed position toward the syringe port. The priming indicator presents the first indicator portion through the indicator window in the unprimed position and presents the second indicator portion through the indicator window in the primed position.
