ABSTRACT:
A hypodermic syringe assembly comprises a barrel with an axial bore, a hollow tip integral with the barrel having an internal surface defining a passageway communicating with the axial bore and also having a tapered external surface adapted to mate with the female tapered surface of a conventional needle hub, a needle hub having a bore therethrough removably positioned in and occupying substantially the entire volume of the passageway and a hollow needle secured within the bore of the hub in fluid communication with the axial bore of the barrel. The syringe assembly may be used with the unique hub positioned within the passageway to provide a substantially air-free syringe or the hub and needle may be removed from the tip to permit a conventional needle hub to be placed thereon.
