1. A catheter system, comprising:
a catheter assembly, comprising:
a catheter hub, comprising a distal end, a proximal end, a lumen disposed between the distal end and the proximal end, a push tab extending outwardly from an upper surface of the catheter hub, a first rib, a second rib proximal to the first rib, and a third rib proximal to the second rib, wherein the first rib, the second rib, and the third rib are shorter in height than the push tab, proximal to the push tab, and extend outwardly from the upper surface of the catheter hub, wherein the first rib is shorter in height than the second rib, wherein the second rib is shorter in height than the third rib;
a septum disposed within the lumen of the catheter hub; and
a catheter tube extending distally from the distal end of the catheter hub;
a needle hub; and
an introducer needle secured within the needle hub and extending through the catheter tube, wherein the introducer needle comprises a flashback notch, wherein the catheter system is configured such that in response to insertion of the introducer needle into vasculature, blood flows into the introducer needle, through the flashback notch, between an outer surface of the introducer needle and an inner surface of the catheter tube, and into a flashback chamber disposed between a distal face of the septum and a proximal end of the catheter tube.
