摘要：
An extravascular system is provided which includes a catheter adapter having a blood control septum configured to control flow of a fluid through the catheter adapter, the catheter adapter further having a catheter configured for intravenous insertion. The extravascular system further includes a septum activator slidably inserted within the catheter adapter and configured for advancement through the blood control septum to provide a fluid pathway through the blood control septum. Further still, the extravascular system includes an external safety mechanism comprising a needle hub and a needle shield interconnected via a tether, wherein the needle shield includes a safety clip that is configured to retain a sharpened end of the introducer needle within the needle shield. Some implementations further comprise an access port forming a portion of the catheter adapter and providing selective access to the lumen of the catheter adapter.
