Abstract

A self-capping syringe is provided, which consists of a barrel having a first end and a second end. A finger flange is on the first end and a needle hub is on the second end of the barrel. A
plunger slides within the barrel and extends from the finger flange, while a thumb rest is on an outer end of the plunger. A needle extends axially outward from the needle hub on the second end of the barrel.
A protective cap is also provided. A mechanism is for allowing the protective cap to twist upon the barrel from a retracted position that exposes the needle to an extended position which covers the needle. A structure is for locking the protective cap in the extended position after use, so as to prevent an accidental needle stick before disposal.
