Needle assembly |
摘要 |
A blood collection set including a non-patient needle assembly interconnected with an intravenous needle assembly through tubing is provided. The non-patient needle assembly includes a hub assembly adapted for mounting with a blood collection set, and an internal blunting member including a blunted tip. The non-patient needle assembly further includes an external cannula concentric with the internal blunting member and including a non-patient puncture tip adjacent the blunted tip. The external cannula is axially displaceable with respect to the hub assembly between a first retracted position in which the non-patient puncture tip extends beyond the blunted tip and a second activated position in which blunted tip extends beyond the non-patient puncture tip.
