An IV catheter system comprising an insertion configuration and a fluid delivery configuration, the IV catheter system comprising: a catheter component comprising: a catheter hub comprising a catheter hub distal end and a catheter hub proximal end, wherein the catheter hub is shaped to define a chamber extending between the catheter hub distal end and the catheter hub proximal end, and a needle port at the catheter hub proximal end that provides access to the chamber; a cannula extending distally from the catheter hub distal end along a cannula axis; and a push feature extending outward from the catheter hub, wherein the push feature comprises an outer surface positioned to receive contact from a digit such that the digit urges the IV catheter system to move from the insertion configuration to the fluid delivery configuration; and a needle component comprising: a needle hub comprising a needle hub distal end and a needle hub proximal end; and a needle extending distally from the needle hub distal end along a needle axis; wherein, in the insertion configuration, the needle is positioned within the cannula and the needle hub distal end is seated in the needle port; wherein, in the fluid delivery configuration, the needle is positioned outside the catheter hub; wherein the push feature is formed of a flexible material that causes the push feature, in response to pressure exerted on the outer surface by a dressing when it is securing the catheter component to a patient, to flex such that the outer surface deflects toward the cannula axis; and characterized in that the push feature comprises: a plurality of adjacent surfaces adjacent to and angled relative to the outer surface; and a plurality of rounds positioned to join the outer surface with each of the adjacent surfaces in a manner that avoids puncturing the dressing. a catheter hub comprising a catheter hub distal end and a catheter hub proximal end, wherein the catheter hub is shaped to define a chamber extending between the catheter hub distal end and the catheter hub proximal end, and a needle port at the catheter hub proximal end that provides access to the chamber; a cannula extending distally from the catheter hub distal end along a cannula axis; and a push feature extending outward from the catheter hub, wherein the push feature comprises an outer surface positioned to receive contact from a digit such that the digit urges the IV catheter system to move from the insertion configuration to the fluid delivery configuration; and a needle component comprising: a needle hub comprising a needle hub distal end and a needle hub proximal end; and a needle extending distally from the needle hub distal end along a needle axis; wherein, in the insertion configuration, the needle is positioned within the cannula and the needle hub distal end is seated in the needle port; wherein, in the fluid delivery configuration, the needle is positioned outside the catheter hub; wherein the push feature is formed of a flexible material that causes the push feature, in response to pressure exerted on the outer surface by a dressing when it is securing the catheter component to a patient, to flex such that the outer surface deflects toward the cannula axis; and characterized in that the push feature comprises: a plurality of adjacent surfaces adjacent to and angled relative to the outer surface; and a plurality of rounds positioned to join the outer surface with each of the adjacent surfaces in a manner that avoids puncturing the dressing. a needle hub comprising a needle hub distal end and a needle hub proximal end; and a needle extending distally from the needle hub distal end along a needle axis; wherein, in the insertion configuration, the needle is positioned within the cannula and the needle hub distal end is seated in the needle port; wherein, in the fluid delivery configuration, the needle is positioned outside the catheter hub; wherein the push feature is formed of a flexible material that causes the push feature, in response to pressure exerted on the outer surface by a dressing when it is securing the catheter component to a patient, to flex such that the outer surface deflects toward the cannula axis; and characterized in that the push feature comprises: a plurality of adjacent surfaces adjacent to and angled relative to the outer surface; and a plurality of rounds positioned to join the outer surface with each of the adjacent surfaces in a manner that avoids puncturing the dressing. a plurality of adjacent surfaces adjacent to and angled relative to the outer surface; and a plurality of rounds positioned to join the outer surface with each of the adjacent surfaces in a manner that avoids puncturing the dressing.
