MEDICAL DEVICE WITH ANTI-ROTATION PUSH TAB

Abstract: a catheter system may include a catheter hub, a septum disposed within the catheter hub, a catheter tube extending from the catheter hub, a needle hub, and an introducer needle secured within the needle hub. the catheter hub may include a push tab and one or more ribs, which may extend outwardly from an upper surface of the catheter hub. the ribs may be shorter in height than the push tab and/or may be generally parallel to the push tab. the introducer needle may include a flashback notch. in response to insertion of the introducer needle into vasculature, blood may flow into the introducer needle, through the flashback notch, and into a flashback chamber disposed between the septum and the catheter tube. the flashback chamber may be disposed distal to the push tab and the ribs, which may improve visualization of the flashback chamber by a user.
