Beschreibung
Zusammenfassung:	A needle and pre-fidled syringe system (10) that provides ultra-low waste and automatic neediestick protection. A syringe assembly (12) is pre-filled with a material (15). A needle head assembly (14) attaches to the syringe assembly (12). A spacer (54) is disposed between the needle head assembly (14) and the syringe assembly (12). The spacer (54) has a central opening (56). The needle head assembly (14) supports a needle (16) with a needle base (20). When assembled, the needle base (20) passes into the central opening (56) of the spacer (54). The needle head assembly (14) also contains a safety slide (22) that can selectively cover the needle (16). During an injection, pressure and/or contact with the plunger head (52) causes the spacer (54) to contact and move the safety slide (22). The safety slide (22) moves to cover the needle (16) during the injection procedure, therein rendering the needle (16) safe.
