A free jet dosage system serves for administering a fluid into an eye. The free jet dosage system includes a micropump having an inlet and an outlet, the micropump being configured to transfer the fluid from the inlet to the outlet and to dispense the fluid at the outlet to the eye as a free jet. The free jet dosage system further includes a sensor configured to sense the eye and to controller a control, and a micropump, wherein the controller is configured to activate the micropump as soon as the eye is sensed by the sensor.

Free jet dosage system for the eye

The invention relates to an apparatus having a pressure chamber and a micropump in fluid connection with the pressure chamber. The pressure chamber includes a gas-carrying region and a liquid-carrying region. The micropump is configured to generate a pneumatic pressure within the gas-carrying region that is lower than a fluid pressure of a liquid flowing through the liquid-carrying region. According to the invention, a gas-permeable and liquid-impermeable separating element separates, at least in sections, the gas-carrying region and the liquid-carrying region. According to the present invention, the micropump is disposed on the pressure chamber.
