Safety device for a sheathed, prefilled injection syringe

A system for safely removing the sheath from a sheathed prefilled injection syringe that has an attached elongated needle guard that defines an axis, and for reconfiguring the distal tip of the needle guard to be radially proximate to the syringe needle, said system comprising:

• a ring for reconfiguring the distal tip of the needle guard, said ring being positionable over the needle guard and moveable from a first position, wherein the distal tip of the needle guard is in a radially expanded configuration to allow the sheath to pass through the distal tip during attachment of the needle guard to the syringe, to a second position wherein the distal tip of the needle guard is radially proximate to the syringe needle;
• and
• a cover positionable over said needle guard and engageable with said ring and the sheath of the syringe, said cover having a means for removing said sheath from said prefilled syringe and for moving said ring from said first position to said second position to reconfigure the distal tip of the needle guard, as said cover is withdrawn from the needle guard.

A system for safely removing the sheath from a sheathed prefilled injection syringe that has an attached needle guard, and reconfiguring the distal tip of the needle guard to be radially proximate to the syringe needle, said system comprising:

• a means for reconfiguring the distal tip of the needle guard from an expanded configuration wherein said distal tip of said needle guard is distanced from the syringe needle to allow the sheath to pass through the needle guard during attachment of the needle guard to the syringe, to a configuration wherein the distal tip of the needle guard is proximate to the syringe needle to cover and protect the syringe needle after an injection;
• and
• a means for removing said sheath from said prefilled syringe and for activating said reconfiguring means.
