摘要：
A safety needle assembly of an infusion set for infusing fluids into a subcutaneously implanted access port is disclosed. The needle assembly is configured to prevent fluid/vapor escape therefrom so as to reduce or prevent fluid exposure to a clinician using the needle assembly. In one embodiment, the needle assembly comprises a handle portion including a needle extending therefrom, the needle defining a lumen for passage of a fluid therethrough. The needle assembly also includes a safety assembly defining a needle hole through which the needle initially extends. The safety assembly is selectively and axially slidable along the needle in order to shield a distal tip of the needle and prevent user contact therewith. A fluid isolation component is included in the safety assembly for isolating fluid escape from the needle to prevent exposure to a clinician.
