Abstract

A dual blunting needle assembly for use in blood collection procedures is provided. The needle assembly includes a hub assembly having a first external cannula with an intravenous puncture tip, a second external cannula with an external blunt tip and an internal lumen extending through the hub assembly from the intravenous puncture tip to the blunt tip. The needle assembly further includes an internal cannula extending concentrically within the internal lumen of the hub assembly. The internal cannula includes an internal blunt tip at a first end and a non-patient puncture tip at a second end.

The internal cannula is adapted for axial movement within the internal lumen of the hub assembly between a first position in which the intravenous puncture tip and the non-patient puncture tip extend beyond the internal blunt tip and the external blunt tip, respectively, and a second position in which the internal blunt tip and the external blunt tip extend beyond the intravenous puncture tip and the non-patient puncture tip, respectively. The needle assembly can further be used in connection with a needle holder to provide a safety assembly.
