Abstract
An intravenous (IV) catheter system may include a catheter adapter having a proximal end and a distal end. The IV catheter system may also include a cannula extending through the catheter adapter. A proximal end of the cannula may include a notch. The IV catheter system may also include a needle hub, which may be coupled to the proximal end of the catheter adapter. The needle hub may include a flashback chamber, which may be in fluid communication with the notch when the IV catheter system is in an insertion configuration.
