Abstract: A dosing device for dispensing a medium into an environment is disclosed, with a dosing space which is formed by contiguous wall portions and is substantially closed off from an environment; with at least one inlet which passes through at least one wall portion for a communicating connection between the dosing space and a medium reservoir, with a dosing aperture arrangement which passes through at least one wall portion for a communicating connection between the dosing space and the environment, and with at least one vibration means which is fitted on at least one wall portion and which is provided to cause oscillation of at least one wall portion of the dosing space. The dosing aperture arrangement is designed as a separate component and is integrated in a wall portion.

Abstract: 1. Microdosing device and method for dosing small liquid quantities.

Abstract: Such dispensers must be easy to grasp or operate by a user, e.g. a user suffering from rheumatoid arthritis and whose capacity to manipulate objects is under certain circumstances limited. In addition, the dispenser must have a simple, inexpensive construction from a minimum number of components. The dispenser is used for the discharge of media, particularly fluids, e.g. a liquid, which preferably contain a pharmaceutical substance, as described in exemplified manner hereinbefore. In the case of the dispenser, the medium is discharged in at least two proportioned partial charges by actuating an actuating means. As a result of the actuation of the actuating means, a relative movement is produced between the actuating means and a housing having a dispenser discharge opening. According to the invention an elastically deformable material bridge is provided. The actuating means is held on the housing by means of the elastically deformable material bridge.
