Abstract:
1. A device for injecting a fluid dose into a body of a patient comprising: a needle-free injecting assembly constructed and arranged to deliver the fluid dose into the body, the needle-free injecting assembly including: a fluid delivery assembly configured to deliver the fluid dose to the needle-free injecting assembly, the fluid delivery assembly including: an adapter removably coupled to the needle-free injecting assembly and fluidly coupling the cartridge to the needle-free injecting assembly, the adapter having a fluid flow passage extending transverse to an axis extending along a length of the needle-free injecting assembly, wherein the sensing assembly directs the drive train to apply a force to the movable piston for overcoming adhesion or static friction between the movable piston and the cartridge while the vacuum force draws the fluid dose from the cartridge through the adapter and into the injection chamber of the needle-free injecting assembly.
