Pre-filled ampule and non-invasive hypodermic injection device assembly

An ampule and a non-invasive hypodermic injection device assembly comprising:

• an injection device including a housing having an ampule-receiving chamber, a gas charge, and means for delivering a predetermined amount of gas to said ampule-receiving chamber;
• and
• a pre-filled ampule having a predetermined amount of medication therein, said ampule comprising:
• an elongate, ampule body having a plunger end and an orifice end, an elongate, medication holder-retaining area having one end thereof adjacent to said plunger end and the other end thereof located intermediate the ends of said body and an elongate transfer area having one end thereof located adjacent to said orifice end and the other end thereof located adjacent said medication holder-retaining area other end;
• an elongate medication holder formed from a non-absorbing, non-diffusing, non-reacting material received in said medication holder-retaining area and having a free, plunger-receiving end located co-terminally with said plunger end;
• a plunger having one end thereof received in and closing said plunger-receiving end, the other end thereof being received in said ampule-receiving chamber for action thereon by said gas charge;
• a floating seal received in and closing the other end of said medication holder-retaining area;
• orifice means for forming a skin-piercing injection stream located at one end of said transfer area including an ampule end bushing at least partially received in said transfer area, a needle orifice holder having a truncated hypodermic needle carried thereon, an orifice end cap received on said end bushing and retaining said orifice holder thereon, and which further includes a needle standoff constructed and arranged to prevent penetration of the skin of an injection-receiving patient by said needle;
• a bypass area located adjacent said one end of said transfer area, said bypass area including key ways therein constructed and arranged to provide passage for medication from said transfer area to said orifice means with said floating seal positioned in said bypass area;
• and
• attachment means for securing said ampule to said device.
