Patent Images
1. An intravenous device, comprising:
- a needle adapter having a proximal end, a distal end, an outer surface and an inner compartment;
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, and a fluid pathway extending through the catheter tube, the catheter adapter, the extension tube and the luer adapter, wherein a portion of the catheter assembly is selectively housed within the inner compartment of the needle adapter; and
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 the distal end extending beyond a tip portion of the catheter tube, wherein the body of the introducer needle extends through the fluid pathway of the catheter assembly.
