Abstract

A syringe includes a hollow barrel and a hollow plunger extending into the barrel and being axially movable within the barrel, where the plunger includes an end wall that is releasably secured to the plunger at an opening disposed at a distal end of the plunger and is movable to disengage with the plunger distal end opening during use of the syringe to facilitate access to a retraction cavity disposed within the plunger. A needle assembly is secured within and at a distal end of the barrel. The needle assembly includes a needle holder with a connector to secure a needle to the needle holder. The needle holder is biased toward the proximal end of the barrel and is configured to be forced into the retraction cavity of the plunger upon complete depression of the plunger distally within the barrel, and the plunger includes at least one protrusion that extends from an internal wall surface of the plunger within the retraction cavity and is configured to engage with and limit or prevent movement of portions of the needle assembly that have been forced into the retraction cavity.
