Abstract
This present disclosure provides a non-coring vial access cannula which has sufficient structural strength that it may be made from a thermoplastic resin instead of metal, thus reducing the likelihood and severity of operator injury by an accidental needle stick. The vial access cannula of the present disclosure has (i) a needle hub suitable for receiving a hypodermic syringe or an IV set (e.g., a Luer lock), (ii) a cannula portion having a centrally disposed lumen, wherein the centrally disposed lumen terminates in one or more distal openings and is in fluid communication with the needle hub, and (iii) a solid tip member distal to the one or more distal openings, wherein the solid tip member has a blade with a cutting edge.
