ABSTRACT:
A unit dose syringe comprises a fluid-containing plastic bag with an attached needle and a dimensionally-stable shell like a woman's compact. The shell contains a thumb-operated slider assembly for advancing the needle to an exposed position for fluid delivery. The syringe also includes a spring-biasing arrangement to return the needle, automatically, to the protected position, after use, and a means for rupturing the bag and retaining the needle in the protected position.
