<p>A device for injecting a fluid product comprises a cylindrical cartridge (2) which contains a fluid product (3) to be injected, a resilient plunger (4) mounted for sliding in a leaktight manner inside the cartridge (2) and movable along the axis thereof, and a tube (13, 22) which comprises a delivery duct (16) with an outlet opening. The device further comprises means for resiliently deforming the resilient plunger (4). An axial movement of the tube (13, 22) relative to the cartridge (2) causes the resilient deformation means to interact with the resilient plunger (4) and at least one communication channel (5, 10, 17, 25) to be opened for the fluid from the cartridge (2) to the delivery duct (16), in use.</p> |
