Abstract
A syringe system and components thereof are disclosed. The system may include a syringe body having a hollow lumen, a proximal open end, and a distal end. The syringe body may be configured to house a fluid therein. The syringe system may further include a plunger positioned in the hollow lumen of the syringe body, forming a seal with an inner wall of the syringe body. The plunger may include a removable piston having a shaft extending from the distal end towards the proximal open end, a stopper removably connected to a distal portion of the shaft, and at least one coupler attached to the distal portion of the shaft. The stopper may be configured to slidably move within the hollow lumen to facilitate movement of the fluid within the syringe body. The coupler may be configured to facilitate removal and attachment of the stopper from the piston.
