Claim Text:
1. 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 and an elongate member slideable alongside the needle shaft as the needle guard is moved between the ready state and the activated state, the arm including a proximal section, a mid-section and a distal section, the proximal section having a first width and the distal section having a second width, the mid-section having a portion of a reduced width, the reduced width being less than one or both of the first and second widths so that an indentation is provided in a side of the arm, the arm intersecting the needle shaft along the reduced width portion of the mid-section of the arm located between the proximal and distal sections, when the needle is in the ready position and the retracted position the elongate member extends through the indentation in the mid-section of the arm, 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 the distal section of the arm resides on a distal section of the elongate member near the distal end of the elongate member where at least a portion of the distal section of the arm is urged against an outer side 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 distal section of the arm is able to move distally along the outer side of the distal section of the elongate member past the distal end of the elongate member and is able to move radially inward to at least partially lie over the fixed open distal end of the elongate member, the arm extends distally from a base having an aperture formed therein with the needle shaft passing through the aperture formed in the base, the elongate member comprises a proximal section that is 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.
