The invention relates to a device 1 for dosing and dry nebulization of nebulizable material 12 chosen from the group comprising anti-infective agents and immunomodulators, comprising a nebulization channel 3, which has a first attachment piece and a second attachment piece, and a source of compressed carrier gas connected to the first attachment piece via a valve 16 for the purpose of sending a carrier gas pressure pulse into the nebulization channel. The device is characterized in that between the first attachment piece and second attachment piece, and above the nebulization channel, a reservoir 10 open only towards the nebulization channel, which contains the nebulizable material 12, is connected to the nebulization channel such that it is gas-tight with respect to the environment, and that, when the valve is closed, a pressure compensation takes place in the nebulization channel and in the reservoir. The invention also relates to a method for dosing and dry nebulization of such a nebulizable material by means of such a device.

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.

The invention relates to a device (1) for dosing and dry nebulization of nebulizable material, comprising a nebulization channel (3), which has a first attachment piece and a second attachment piece, and a source of compressed carrier gas connected to the first attachment piece via a valve for the purpose of sending a carrier gas pressure pulse into the nebulization channel. The device is characterized in that between the first attachment piece and second attachment piece, and above the nebulization channel, a reservoir open only towards the nebulization channel, and used for receiving the nebulizable material, is connected to the nebulization channel such that it is gas-tight with respect to the environment, and that, when the valve is closed, a pressure compensation takes place in the nebulization channel and in the reservoir. The invention also relates to the use of this device for inhaled administration of a powdered pharmaceutical preparation, and to a method for dosing and dry nebulization of nebulizable material by means of such a device.
