Abstract

A needle-free injection device in which a gas cartridge or other source of pressurized gas is used to advance a piston and forcibly expel injectable fluid out through an injection orifice. When a gas cartridge is used, the gas cartridge may be moveable from an initial position to an actuating position in which gas is released to drive the injection, and a recoil inhibiter may be employed to prevent the gas cartridge from moving back to the initial position. A gas cartridge seal may be disposed on the gas cartridge and moveable with the gas cartridge to seal the gas cartridge against an interior wall of a gas cartridge housing. The needle-free injection device may also be configured so that sealing is compromised upon full advancement of the piston, so as to depressurize the device after delivery of an injection.
