Dual blunting needle assembly

摘要

A safety needle assembly which is adapted for blunting of both an intravenous puncture tip and a non-patient puncture tip is provided. The needle assembly includes a cannula having a first end with an intravenous puncture tip and a second end with a non-patient puncture tip, and a blunting member in concentric relation with the cannula which includes a first blunt end proximate the intravenous puncture tip of the cannula and a second blunt end proximate the non-patient puncture tip of the cannula. An actuator is in engagement with the blunting member and the cannula. Activation of the actuator causes blunting of the intravenous puncture tip and the non-patient puncture tip by the blunting member. The needle assembly is particularly useful in connection with a blood collection system.
