A catheter insertion device, including a housing having a base (504, 604, 704), a flexible beam (510, 610, 710) movably disposed within the housing, an insertion needle (514, 614) connected with the beam, and a holder (518, 618, 718) movably disposed within the housing and movably connected with the insertion needle. The device also includes a catheter (522, 622, 722) connected with the holder to displace therewith, the catheter surrounding at least a portion of the insertion needle, and an actuator button (502, 602, 702) movably connected to the housing and configured to flex the beam upon actuation, thereby displacing the insertion needle and the catheter to an extended position in which respective distal portions of the insertion needle and the catheter extend outside the housing through the base.
