Patent ID: 7938800

Claim:
A needleshield assembly, comprising: a dispensing device attachment member adapted to attach the needleshield assembly to a needle hub of a dispensing device; an extensible frame comprising a distal member and a proximal member, the extensible frame connected to a proximal end of the dispensing device attachment member by a first hinge, the distal member and the proximal member connected by a second hinge at a distal end of the proximal member and a proximal end of the distal member, the extensible frame having a collapsed position and an extended position; and an actuator attached to the proximal end of the dispensing device attachment member by a third hinge, the actuator adapted to direct the extensible frame from the collapsed position to the extended position, the actuator further comprising a blocking protrusion adapted to puncture a wall of the dispensing device attachment member and block the fluid path when the extensible frame is in the extended position; and a retaining member adapted to secure the blocking protrusion in the fluid path.
