Abstract:
A single dose, prefilled, disposable syringe is provided in which an outer casing surrounding the syringe in the packaged state is collapsible to act as a plunger during use of the syringe. The outer casing has a series of longitudinal grooves formed around its circumference to facilitate collapsing of the outer casing. The collapsed outer casing has a smaller diameter than the barrel of the syringe so that the collapsed outer casing can push the piston through the barrel of the syringe to eject the single dose of medication.
