A needle guard may include a base portion having a hole adapted to accommodate a needle shaft of a needle such that the needle may extend through the hole and move relative to the needle guard from a ready position in which the needle tip is outside the needle guard to a protective position in which the needle tip is covered by the needle guard. Arms of the needle guard may extend distally from the base portion generally in an axial direction. The arms may comprise sections bent to define a passage for the needle in the needle guard. An intravenous catheter apparatus may include the needle guard in combination with a needle and a catheter tube attached to a catheter hub, the catheter hub having a chamber. The needle guard may be slidably arranged on the needle shaft and housed in the chamber of the catheter hub. |
