1. A safety device comprising:
a needle fitting configured to mount with a needle;
a sheath having a proximal end disposed with the needle fitting and a distal end, the sheath including elongated arms that
extend between the proximal end and the distal end,
a mid portion of the arms being pivotable towards and away from the needle to facilitate movement of the distal end of the
sheath from a first position spaced from a distal end of the needle to a second position disposed adjacent a distal end of
the needle;
a resilient member engaging the arms to facilitate extension of the distal end of the sheath to the second position,
wherein in the second position, the mid portion of the arms are in opposing relation with each other;
wherein each of the elongated arms includes a front half and a back half, each back half being pivotally connected to its
respective front half; and
wherein the proximal end of the sheath is hingedly connected to a back member.
