Claim 0:
1. A vascular access device, comprising:
a catheter assembly comprising a catheter adapter having a distal end from which a catheter extends, a first port formed at a proximal end by which an introducer needle having a sharp distal tip for puncturing and configured to introduce the catheter into vasculature is selectively coupled to the catheter adapter, a lumen extending between the distal end and the proximal end of the catheter adapter, and a side port positioned between the distal end and the proximal end of the catheter adapter; and
an extension comprising:
a housing having a proximal end, a distal end having a luer fitting that is coupled to the side port of the catheter adapter, and a slot, wherein the slot comprises a proximal end and a distal end, wherein the proximal end of the slot is distal to the proximal end of the housing; and
another catheter disposed within the housing, wherein the another catheter comprises a proximal end and a distal portion forming a blunt distal tip through which blood can be collected, wherein the proximal end of the another catheter extends out through the slot to form a blood collection adapter, the proximal end of the another catheter, including the blood collection adapter, being configured to move along the slot from a proximal position distal to the proximal end of the slot to a distal position, wherein the vascular access device is configured such that, when the proximal end of the another catheter is in the proximal position distal to the proximal end of the slot, the blunt distal tip of the another catheter is disposed within the housing, wherein in response to movement of the proximal end of the another catheter from the proximal position to the distal position and withdrawal of the introducer needle, the blunt distal tip of the another catheter is configured to advance out through the catheter to thereby enable blood to be collected directly from a patient's vasculature via the blood collection adapter, and wherein the lumen is aligned with the first port when the another catheter is in the distal position.
