Abstract
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.
Claims17
A free jet dosage system for administering a fluid into an eye, comprising:
- a micropump comprising 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;
- a sensor configured to sense the eye;
- and
- a controller for controlling the micropump configured to activate the micropump as soon as the eye is sensed by the sensor;
- wherein the sensor is configured to detect blinking of the eye, and wherein the controller is configured to determine, based on the detected blinking of the eye as a reaction within a reaction time window after the administering, that administering the fluid into the eye was successful;
- wherein the controller is configured to deactivate the micro dosage pump in response to the detected blinking of the eye so that no further free jet is dispensed.
