ABSTRACT:
The combination of a syringe which includes a barrel and a needle projecting from one end of the barrel, and a protector slidably mounted on the syringe barrel. A guard portion in the protector shields the tip of the needle with the protector relatively fully extended on the barrel, and in this position a seal inside the protector seals the tip of the needle. The needle is exposed with the protector in a relatively fully retracted position. In an intermediate position, the needle is shielded but the tip is not sealed.
