a needle hub having a closed end, an open end, and a compartment interposed therebetween, the closed end being configured to receive a terminal end of the extension tube and the open end configured to receive the proximal end of the catheter adapter, wherein the extension tube is stored within the compartment, the needle hub having an access slot extending through the open end, wherein the access port extends through the access slot and is slidable in a distal direction within the access slot; and an introducer needle having a base end, a tip end and a body extending therebetween, the base end being securely attached to the closed end of the needle hub, and the body extending through the proximal end, the lumen, the distal end, and the intravenous catheter such that the tip end of the introducer needle is exposed beyond a terminal end of the intravenous catheter. ### Claim 2 (depends on 1) The device of claim 1, wherein the body of the introducer needle further passes through an interior of the extension tube. ### Claim 3 (depends on 1) The device of claim 1, wherein the proximal end of the catheter adapter further comprises a blood control valve through which the body of the introducer needle passes. ### Claim 4 (depends on 3) The device of claim 3, wherein the blood control valve comprises a septum. ### Claim 5 (depends on 3) The device of claim 3, wherein the blood control valve comprises a self-sealing polymer. ### Claim 6 (depends on 1) The device of claim 1, wherein the access port is located externally to the compartment. ### Claim 7 (depends on 1) The device of claim 1, wherein the open end further comprises a notch for receiving a proximal edge of the securement platform. ### Claim 8 (depends on 1) The device of claim 1, further comprising a safety mechanism slidably coupled to the body of the introducer needle and configured to capture and retain the tip end of the introducer needle upon removal of the catheter adapter and the extension tube from the needle hub. ### Claim 9 (depends on 1) The device of claim 1, wherein a proximal end of the extension tube further comprises a blood control valve. ### Claim 10 (depends on 9) The device of claim 9, wherein the blood control valve further comprises a passageway through which the body of the introducer needle passes. ### Claim 11 (depends on 9) The device of claim 9, wherein the blood control valve is a septum. ### Claim 12 (depends on 9) The device of claim 9, wherein the blood control valve is a self-sealing polymer. ### Claim 13 (depends on 9) The device of claim 9, wherein the blood control valve is a luer adapter. ### Claim 14 (depends on 1) The device of claim 1, wherein a gauge of the extension tube is greater than a gauge of the intravenous catheter. ### Claim 15 (depends on 1) The device of claim 1, wherein the securement platform comprises a pliable, flexible polymer material. ### Claim 16 (depends on 1) The device of claim 1, wherein the needle hub comprises a rigid polymer material. ### Claim 17 (depends on 16) The device of claim 16, wherein the needle hub further comprises a paddle grip positioned in proximity to the open end and arranged to overlap the securement platform. ### Claim 18 (depends on 17) The device of claim 17, wherein the device is low profile. ### Claim 19 (depends on 1) The device of claim 1, wherein the closed end of the needle hub further comprises a flashback chamber.
