ABSTRACT:
An improved hand syringe has been provided which allows a used needle to be retracted completely into the body of the syringe, and stored there such that the spent needle cannot be used again. This improvement thereby provides safety from accidental infection to persons required to use hand syringes as well as persons required to dispose of these syringes.
