Abstract
A needle-free injector for injecting fluid from an injection cartridge that has a longitudinal axis, an injection orifice at a distal end and a displaceable plunger. The needle-free injector includes an injector body having a longitudinal axis and a side opening to receive the cartridge from a position laterally offset from the injector body longitudinal axis. The needle-free injector further includes a system disposed in the injector body for providing injection power and a ram for transferring power from the system to the plunger. The ram is disposed in the injector body and is axially aligned with the longitudinal axis of the cartridge when the cartridge is in position in the injector body. The needle-free injector further includes a closure mechanism for closing the side opening of the injector body after the cartridge is in position in the injector body to lock the cartridge in place in the injector body. The disclosure also includes other apparatus and methods as discussed in detail herein.
