A free-jet dosing system for administering a fluid into or under the skin having a micropump and a nozzle arranged on the outlet side. The micropump has an inlet and an outlet and is configured to transport a fluid from the inlet to the outlet and to generate a blocking pressure of at least 20 bar at the outlet. The nozzle is configured to output the fluid output at the outlet as a free jet at a fluid pressure so that the fluid of the free jet may be injected into the skin.
