Abstract
An automatically retracting safety needle assembly configured to receive a syringe. The assembly has distal and proximal ends, and comprises: A moving sleeve (MOS): at least partially within the IH; having a flange wall; axially movable. A biasing element (BE), within the IH, biasing the MOS proximally. A syringe, receiving a plunger rod; movable axially within the IH, and coupled to the MOS. An activation fork (AF), partially disposed within the IH. AF has a guiding arm coupled with the IH and the MOS; preventing motion of the MOS during non-deployment state. An automatic retraction mechanism, retracting the syringe after injection. Deployment: advance plunger rod and the AF axially (distally), until AF guiding arm allows proximal movement of the MOS, retracting the syringe. Distal advancement of plunger rod is constant without an abrupt increase in resistive force; allowing safe disposal.
