An assembled intravenous catheter device, comprising: a catheter adapter having a proximal end, a distal end, and a lumen interposed therebetween, the catheter adapter further comprising a securement platform, the distal end comprising an intravenous catheter and the proximal end comprising an extension tube and an access port coupled to a sidewall surface of the extension tube and extending outwardly therefrom, wherein the intravenous catheter, the access port, and the extension tube are in fluid communication with the lumen; 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; 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, characterized in that the needle hub has an access slot extending proximally from the open end to a position that is in proximity to the closed end, whereby the access port passes through the access slot and is located externally to the compartment of the needle hub when the intravenous catheter device is assembled, the access slot having a width that is slightly larger than the outer diameter of the access port, whereby the access port is able to freely slide within the access slot. a catheter adapter having a proximal end, a distal end, and a lumen interposed therebetween, the catheter adapter further comprising a securement platform, the distal end comprising an intravenous catheter and the proximal end comprising an extension tube and an access port coupled to a sidewall surface of the extension tube and extending outwardly therefrom, wherein the intravenous catheter, the access port, and the extension tube are in fluid communication with the lumen; 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; 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, characterized in that the needle hub has an access slot extending proximally from the open end to a position that is in proximity to the closed end, whereby the access port passes through the access slot and is located externally to the compartment of the needle hub when the intravenous catheter device is assembled, the access slot having a width that is slightly larger than the outer diameter of the access port, whereby the access port is able to freely slide within the access slot.
