RETRACTING NEEDLE SAFETY DEVICE.

摘要

A retractable safety needle assembly (24) is provided. The needle assembly includes a tubular outer body (20), a retraction assembly (60) contained with the outer body (20) and a biasing element (88) for applying a retraction force therebetween. The retraction assembly (60) includes a cannula (62) having an intravenous puncture tip (64) and a non-patient puncture tip (66) at opposing ends. In a first position, the intravenous puncture tip (64) extends from a first end (22) of the tubular outer body (20). The retraction assembly (60) is adapted for movement within the tubular outer body from the first position to a second position in which the intravenous puncture tip (64) and the non-patient puncture tip (66) are contained entirely within the tubular outer body (20) and are offset from a general axis defining the outer body (20).
