Quick release plunger
First Claim
1. A syringe system comprising:
- a syringe body comprising a hollow lumen, a proximal open end, and a distal end, the syringe body being configured to house a fluid therein; and
a stopper positioned in the hollow lumen of the syringe body, the stopper forming a seal with an inner wall of the syringe body and configured to slidably move within the hollow lumen to facilitate movement of the fluid within the syringe body, the stopper comprising;
a base, andone or more capture members extending rearwardly from the base, the one or more capture members each comprising a beveled edge,wherein the beveled edge is configured to interact with a piston of a fluid injection apparatus to radially deflect the one or more capture members upon rotation of the stopper relative to the piston to facilitate removal of the stopper from the piston.

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.
