ABSTRACT:
A remote cannula removal cartridge syringe comprising a first barrel, a second barrel, an expandable needle hub, and a modified needle hub receiver. The second barrel is concentric with the first barrel and has a retaining pin which slides within a series of grooves of the first barrel. After use of the syringe the second barrel may be protracted causing the engagement and safe separation of the needle hub from the syringe without requiring the operator to recap the syringe or place fingers near the contaminated needle.
