ABSTRACT:
A device for protectively sheathing a syringe and hypodermic injection or body fluid withdrawal element, which device includes a tubular sheath having a syringe barrel reciprocably mounted within the tubular sheth for coaxial movement. The barrel carries a plunger for moving a liquid through a spout or tip on one end of the barrel. The sheath, near one of its ends, carries a locking element, and the barrel, adjacent its end through which liquid passes upon reciprocation of the plunger, carries a cooperating locking element which interlocks with that locking element carried by the sheath when the barrel is withdrawn into the sheath to a location where the barrel tip is totally encased and any hypodermic injection or fluid withdrawal element which is carried on the tip of the barrel is protected.
