1. An intravenous device, comprising:
a needle adapter having a proximal end, a distal end, an outer surface and an inner compartment, the distal end forming an opening into the inner compartment, a surface of the inner compartment including one or more channels that extend longitudinally along the surface, each channel including a recess positioned towards a distal end of the channel; a catheter assembly including a catheter tube coupled to a catheter adapter, the catheter assembly further including a luer adapter coupled to the catheter adapter via an extension tube, the extension tube being flexible, and a fluid pathway extending through the catheter tube, the catheter adapter, the extension tube and the luer adapter; an introducer needle having a proximal end, a distal end and a body extending therebetween, the proximal end being coupled to the proximal end of the needle adapter; and a safety clip contained within the inner compartment, the safety clip having an aperture through which the introducer needle is inserted, the safety clip further including one or more arms, each arm having a first surface that extends inwardly towards the safety clip and a second surface that extends outwardly away from the arm, the safety clip further including a needle sheath that extends distally from the aperture; wherein, prior to using the peripheral intravenous catheter, the safety clip is in a proximal position in which:
the second surface of each arm is positioned within a corresponding one of the one or more channels and inwardly biased,the luer adapter is positioned within the first surface of each arm, the inward biasing of the second surface causing the first surface to lock the luer adapter within the inner compartment, andthe introducer needle extends distally out through the catheter tube; and wherein, after inserting the catheter tube into a vasculature, the safety clip is configured to slide into a distal position in which: the second surface of each arm is aligned with the recess in the corresponding channel thereby allowing the corresponding arm to extend outwardly to unlock the corresponding first surface from the luer adapter and therefore allow the luer adapter to be removed from within the inner compartment; and the distal end of the introducer needle is contained within the needle sheath. |
