1. A catheter system, comprising:
a catheter secured within a catheter adapter and extending distally beyond a generally cylindrical nose;
the catheter adapter comprising:
a body;
the generally cylindrical nose extending distally from the body and comprising a distal end and a proximal end, wherein the generally cylindrical nose is constructed of a first material;
a strain relief rib extending outwardly from the generally cylindrical nose and along a length between the distal end of the generally cylindrical nose and the proximal end of the generally cylindrical nose, wherein the strain relief rib is constructed of a second material more flexible than the first material, wherein the strain relief rib no more than partially surrounds the catheter, wherein the strain relief rib comprises a distal end and a proximal end, wherein a width of the proximal end of the strain relief rib is less than a width of the generally cylindrical nose;
a bump disposed on the strain relief rib and extending outwardly from the strain relief rib; and
another bump aligned with the bump along a longitudinal axis of the catheter system and extending outwardly from the strain relief rib, wherein the bump and the other bump are constructed of the second material.
