Beschreibung
Zusammenfassung:	A system with a needle head that attaches to a syringe assembly. The syringe assembly contains a barrel and a plunger. The plunger has a bore opening that is accessible from within the barrel. A tubular spacer is disposed within the barrel. The tubular spacer defines a central opening. The needle head has a needle that extends from a needle base. The needle base extends into the central opening of the tubular spacer. A plug is provided that blocks access to the needle. The plug is displaced out of the central opening of the tubular spacer and into the opening in the plunger as the plunger contacts and displaces the tubular spacer in the barrel. As the plug is displaced from the tubular spacer, the plug transfers into the bore opening within the plunger. This enables the plunger to press flush against the tubular spacer.
