Abstract
A fluid injecting device () generally including a fluid delivery assembly () and a needle-free injecting assembly (). The fluid delivery assembly () delivers or transfers the fluid medicine from a cartridge () into the needle-free injecting assembly () for injecting into a patient. A drive train () applies a force to a piston () inside the cartridge () during the delivery of the fluid to the needle-free injecting assembly () to prevent adhesion or static friction between the piston () and the cartridge (). 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.
