  • Syringe and needle assembly
    Patent number: 5328466
    Abstract: A syringe and needle assembly having a means to align the beveled tip of the needle with the volumetric scale on the syringe is disclosed. In the preferred embodiment, a visible mark is placed longitudinally on the hub of the needle on the same side and in coaxial alignment with the beveled tip of the needle. This allows for the needle to be installed on the syringe and the beveled tip quickly aligned with the volumetric scale printed on the syringe body without the need for removing the needle safety cap prior to or during installation.
