Abstract

A single use needleless syringe (10) for administering a fluid medication. The syringe (10) comprises a hollow, tubular body (12) which includes a gas storage portion (14) defining a storage chamber (16) containing a quantity of pressurized gas. The body (12) also includes an ejector portion (18) defining a piston chamber (20) which is selectively placeable into fluid communication with the storage chamber (16) and has a piston (22) movably disposed therein.
