A fluid injecting device (30) generally including a fluid delivery assembly (32) and a needle-free injecting assembly (34). The fluid delivery assembly (32) delivers or transfers the fluid medicine from a cartridge (40) into the needle-free injecting assembly (34) for injecting into a patient. A drive train (112) applies a force to a piston (64) inside the cartridge (40) during the delivery of the fluid to the needle-free injecting assembly (34) to prevent adhesion or static friction between the piston (64) and the cartridge (40). In addition, sensors can be used to help ensure the proper amount of dosage is transferred to the needle-free injecting assembly, conserve power, reduce leakage during disassembly, among other functions.

Dispositif (30) d~injection de fluide comportant généralement un ensemble (32) d~amenée de fluide et un ensemble (34) d~injection sans aiguille. L~ensemble (32) d~amenée de fluide amène ou transfère un médicament fluide d~une cartouche (40) à l~ensemble (34) d~injection sans aiguille en vue de l~injecter dans un patient. Un train d~entraînement (112) exerce une force sur un piston (40) à l~intérieur de la cartouche (40) lorsque le médicament fluide est amené à l~ensemble (34) d~injection sans aiguille pour empêcher toute adhérence ou frottement statique entre le piston (64) et la cartouche (40). Des capteurs peuvent en outre être utilisés, notamment pour faciliter le transfert d~une quantité correcte de médicament fluide vers l~ensemble d~injection sans aiguille, pour économiser l~énergie et pour réduire les fuites lors du démontage.
