SELF-VENTING, NON-CORING NEEDLE ASSEMBLY

摘要

A self-venting, non-coring needle assembly for the transfer of liquid to or from a container includes a hub having a forward end, a rearward end for engaging fluid transfer apparatus and a passageway therethrough. A hollow shaft extends outwardly from the forward end of the hub and has a lumen in fluid communication with the passageway. The shaft includes a closed distal end and an aperture in the side thereof near the distal end and in fluid communication with the lumen. A sleeve is slidably maintained on the shaft. During use, gases are vented by passing freely between the outside of the shaft and the inside dimension of the sleeve.
