description A needle and syringe system, wherein a needle head is attached to a syringe assembly. The syringe assembly includes a syringe barrel and a plunger rod with a plunger head. A needle base is affixed to the syringe barrel. A tubular cavity is formed in the needle base and a post extends through the tubular cavity. A needle extends through the post. A spacer is provided. The spacer is displaced into the tubular cavity within the needle base as the plunger head is advanced within the syringe barrel. A protective cover is disposed about the needle base. The spacer moves the protective cover between a first position and a second position as the spacer is displaced into the tubular cavity. As the protective cover moves between positions, the protective cover surrounds the needle and prevents the needle from causing any inadvertent needle stick injuries.
