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