Claim 18:
19. An intravenous catheter device comprising:
a barrel having an interior;
a slider contained in the interior of the barrel;
a catheter adapter having a proximal end to which a distal end of the slider is coupled;
a catheter that extends distally from the catheter adapter;
a needle hub contained within the interior of the barrel; and
a needle that extends distally from the needle hub, the needle extending through the catheter adapter and the catheter;
wherein a proximal end of the slider is initially positioned towards a proximal end of the barrel and the needle hub is initially retained towards a distal end of the barrel; and
wherein the needle hub is retracted proximally within the barrel when the slider slides distally to a trigger point, the retracting of the needle hub causing a distal tip of the needle to be secured within the slider, wherein the proximal end of the slider is configured to form an interference fit with the trigger point to prevent the slider from sliding proximally relative to the barrel.
