1. A catheter assembly comprising:
a catheter hub comprising a wall having an interior wall surface defining a cavity having a tip protector disposed therein; a catheter tube having a distal opening extending distally of the catheter hub; a needle, which has a lengthwise axis, a sharpened needle tip, and a crimp, a material build up, a bend or combinations thereof, passing through the catheter hub, the tip protector, and the catheter tube with the sharpened needle tip extending distally of the distal opening in a ready to use position; the tip protector being removably held in the cavity of the catheter hub and comprises a proximal wall, a perimeter defining an opening having the needle passing therethrough, a long arm having a free end extending distally of the proximal wall towards the sharpened needle tip and biased by a side of the needle, a short arm having a free end extending distally of the proximal wall towards the sharpened needle tip and being shorter in length relative to the long arm, and a third arm having a free end extending in a proximal direction opposite the long arm and the short arm; the free ends of the long arm, the short arm, and the third arm are spaced apart and movable relative to one another; wherein the crimp, the material build up, the bend or the combinations thereof on the needle is configured to engage the perimeter defining the opening in a protective position in which the free end of the long arm extends across the lengthwise axis of the needle; and wherein the third arm, which extends in the proximal direction, contacts the interior wall of the catheter hub as the tip protector is removably held in the cavity of the catheter hub in the ready to use position. |
