Needle guard

A safety needle device comprising:

• a needle having a needle shaft and a distal tip;
• and
• a needle guard transitional between a ready state where the distal tip of the needle is in an unprotected state and an activated state where the distal tip of the needle is in a protected state, the needle guard comprising an arm having a distal section, the needle guard further comprising an elongate member slideable alongside the needle shaft as the needle guard is moved between the ready state and the activated state, the elongate member having an open proximal end, a fixed open distal end and a through passage extending between the open proximal and distal ends, in the ready state a portion of the distal section of the arm is resiliently urged inward toward the elongate member to reside in a recess in an outer wall of the elongate member so as to assist in maintaining the arm in a fixed axial position on the elongate member when the needle guard is in the ready state, the recess located near the fixed open distal end of the elongate member, the needle guard being configured such that as the needle guard transitions from the ready state to the activated state the portion of the distal section of the arm is able to move distally out of the recess along the outer wall of the elongate member past the open distal end of the elongate member so that the distal section of the arm is able to move radially inward to at least partially lie over the fixed open distal end of the elongate member.
