1. A needle assembly comprising:

  • a needle having a needle shaft and a distal tip; and

    a needle guard comprising an elongate arm having a distal section and an elongate member having a through passage extending between a proximal end and a distal end of the elongate member, the elongate member slideable alongside the needle shaft as the needle is moved between a ready position and a retracted position, in the ready position the distal tip of the needle resides distal to the distal end of the elongate member with a segment of the distal section of the elongate arm being urged against a side of the needle shaft, in the retracted position the distal tip of the needle resides within the elongate member with the segment of the distal section of the elongate arm disengaged with the needle shaft and the distal section of the elongate arm being moved radially inward to at least partially lie over the distal end of the elongate member, when the needle is in the ready position and the retracted position the elongate member extends through a passage in the elongate arm with the elongate arm intersecting the elongate member at a location between the proximal and distal ends of the elongate member, the elongate arm extends distally from a base that contains an aperture, the needle shaft passing through the aperture formed in the base, the elongate member having a proximal section and a distal section, the proximal section of the elongate member being disposed within the aperture of the base with the base being slideable on the proximal section of the elongate member between a first position when the needle guard is in the ready state and a second position distal to the first position when the needle guard is in the activated state, the proximal section of the elongate member and the base having cooperative features that prevent rotational movement of the base on the elongate member.
