Abstract
Abstract An ampoule for a hypodermic jet injector. The end of the ampoule, through which medicament passes, is constructed of a resilient material. Cross-cuts are scribed in the resilient end so that a plunger driving a plug into the opposite end of the ampoule forces medicament through the cross-cut end by bursting it along lines coincident with the cuts. Alternate end cuts, a storage case, and methods for filling the ampoules are also disclosed.

A method for loading medicament into an ampul of the type for use with a hypodermic jet injector unit, wherein said ampul comprises a cylindrically shaped capsule having one open end, one closed end, an inside and an outside, said closed end formed from a flexible, rupturable material and having defined therein a plurality of cuts such that a pressure differential between the inside and outside of said ampul causes medicament to pass in the direction of decreasing pressure through an opening in said closed end defined by rupture of said closed end along said cuts; and a plug fitted into said open end of said ampul to thereby define an enclosed chamber within said ampul for holding medicament, said plug being slidable along the inside of said ampul to cause pressure differential between the inside and outside of said ampul, said method comprising the steps of: positioning said plug on top of a vertical loading rod, forcing said plug into a cylindrical chamber, filling said chamber with medicament, attaching said capsule to the top of said chamber with said open end down, and forcing said plug and Medicament from said chamber and up into said capsule.
