Patent ID: 7972309

Claim:
A non-patient safety needle assembly for mounting with a conventional intravenous blood collection set comprising: a non-patient hub assembly having opposing first and second ends and a central opening extending through said hub assembly from said first end to said second end, said first end adapted for mounting with a blood collection set, an internal blunting member in fixed engagement with said non-patient hub assembly and extending through said central opening of said hub assembly, said internal blunting member having a first end concentric with said non-patient hub assembly, a second end of said blunting member having a blunted tip and an internal lumen extending through said internal blunting member from said first end of said blunting member to said blunted tip, an external non-patient cannula concentric with said internal blunting member and axially displaceable within said non-patient hub assembly, said external non-patient cannula including a non-patient puncture tip adjacent said blunted tip of said internal blunting member, said external non-patient cannula adapted for axial displacement with respect to said non-patient hub assembly about said internal blunting member between a first retracted position in which said non-patient puncture tip extends beyond said blunted tip of said internal blunting member and a second activated position in which said blunted tip of said internal blunting member extends beyond said non-patient puncture tip of said external non-patient cannula, and a sleeve extending about said non-patient puncture tip, wherein said non-patient puncture tip can be inserted into and removed from a blood collection tube having a pierceable membrane while said external non-patient cannula is in said first retracted position.
