ABSTRACT:
The invention is a pre-charged, disposable syringe capable of use by patients. The syringe has a housing with a cover having a central aperture which receives an actuator button. The actuator button extends to an internal piston which is mounted over a medication ampoule. The ampoule has a dependent hypodermic needle which is slidably received in the housing and moves between recessed and projected positions. In its recessed position, the ampoule is totally contained within the housing, and in its projected position, the hypodermic needle projects from the housing. The housing contains an actuator spring, which is compressed and biased to move the piston and the ampoule into its projected position. The medication is discharged from the ampoule by the mechanically coupled piston, or by the release of air from an internal air pressure chamber. The actuator button is locked for safety with a detent and plastic ring or a trigger safety stylet and is covered with a protective, removable cap to prevent accidental or unintended injection of the medication.
