Claim Text:
1. A catheter assembly comprising: a catheter hub; an introducer needle having a lumen extending therethrough; a needle hub coupled to a proximal end of the introducer needle, the needle hub forming an internal chamber having a proximal opening; a flash chamber having a distal end that is positioned within the internal chamber and is removably coupled to the needle hub, an interior of the flash chamber being in fluid communication with the lumen of the introducer needle when the flash chamber is coupled to the needle hub; and a safety barrel removably coupled to the catheter hub, the safety barrel being configured to capture a sharpened distal tip of the introducer needle when the needle hub is withdrawn proximally within the safety barrel, a proximal end of the flash chamber being positioned within the safety barrel prior to the needle hub being withdrawn proximally within the safety barrel, the safety barrel having a proximal opening configured to allow the flash chamber to extend proximally out through the safety barrel when the sharpened distal tip is captured within the safety barrel thereby allowing the flash chamber to be decoupled from the needle hub, the proximal opening being sized to prevent the needle hub from extending through the proximal opening.
