摘要:
The invention relates to a device for dispensing a fixed dose of fluid, the device comprising at least one barrel (42); at least one plunger (27) at least partially enclosed within the barrel (42); a motion conversion mechanism (Ml) for transferring actuated pressure force applied outside the barrel into movement of the at least one plunger (27) in a dispensing direction, wherein the motion conversion mechanism comprises at least one rotating gear; and a releasing mechanism (Rl) for disconnecting the plunger from the motion conversion mechanism, wherein at a released position the at least one plunger (27) can move in a direction opposite to the dispensing direction, independent of a rotational movement of the at least one gear, and wherein the movement of the plunger (27) in the opposite direction to the dispensing enables loading the fluid into the barrel (42).
