摘要：
Various embodiments of syringe assemblies include a syringe barrel and a substantially conical tip or outlet disposed on the distal end of the barrel. The substantially conical tip includes a locking mechanism that engages an extension of a plunger assembly extending from a distal end of the plunger assembly so as to retain the extension within the substantially conical tip or outlet upon full injection of the contents of the syringe to a patient. According to one embodiment, a plunger head of the plunger assembly is slidably disposed on the extension. According to another embodiment, a separate hub, which holds a needle cannula, is disposed on an outlet at the distal end of the syringe barrel, which contains the locking mechanism. According to a further embodiment, the locking mechanism includes a locking clip disposed within the substantially conical tip of the syringe assembly.
