Abstract
A needle assembly is disclosed, which includes a needle hub, a metal cannula and a plastic tip. The needle hub defines a fluid flow path therethrough. The metal cannula is supported on a distal end of the needle hub, where the metal cannula defines a fluid flow path into the distal end of the needle hub. The plastic tip member is connected to a distal end of the metal cannula, where the plastic tip member defines a fluid flow path into the distal end of the metal cannula. Plastic tip further includes a channel groove that runs along the length of the plastic tip to allow fluid to flow into a distal end of the metal cannula. Additionally, the plastic tip member is configured to pierce a septum of a vial.
