US Patent 7399292 Activation of dual blunting needle assembly

A needle assembly that is adapted for blunting of both an intravenous puncture tip and a non-patient puncture tip is provided. The needle assembly includes a hub having an opening, an intravenous puncture tip, a non-patient puncture tip, a first blunting tip in concentric relation with the intravenous puncture tip, and a second blunting tip in concentric relation with the non-patient puncture tip. An actuator extends through the opening and is in engagement with either the first and second blunting tips or the intravenous puncture tip and the non-patient puncture tip. Activation of the actuator causes blunting of the intravenous puncture tip and the non-patient puncture tip by the first and second blunting tips. The needle assembly is particularly useful in connection with a blood collection system.
