ABSTRACT:
An intravenous catheter insertion device comprising an intravenous silastic or Teflon catheter, a hollow-bore steel introducer needle, a break-away needle guide and a needle trap. Prior to catheter insertion the needle is concentric within the catheter with one end extending past the distal end of the catheter. The other end of the needle is releasably attached to a needle guide. After the needle is used to guide the catheter into a vein, the needle guide is withdrawn. As the needle guide is withdrawn, the introducer-needle is drawn out of the intravenous catheter into the needle trap. As the needle guide is further withdrawn, the introducer-needle breaks loose from the needle guide to remain safely housed within the trap. The invention is easily adapted for use with most conventional intravenous catheter assemblies.
