16. Portable soft mist inhaler for propellant-free metered nebulization of a medicament preparation, comprising:
-
an inhaler body a mechanical pressure generator for pressurizing a supply of medicament preparation located in the inhaler body, an expulsion nozzle for receiving a dose of the medicament preparation and for delivering the received dose of the nebulized medicament preparation as an aerosol, and an add-on device mounted on the inhaler body over the expulsion nozzle, the add-on device having a chamber for at least one of receiving and intermediately storing the aerosol, wherein the an add-on device having at least one of the following features; a connector for the introduction of the aerosol into the chamber oriented at a right angle to a main dispensing direction of the chamber; an inlet opening and an air inlet valve for admitting a supply of air into the chamber and for preventing flow in an opposite direction, the inlet valve being arranged upstream of a connector for admitting the aerosol into the chamber; a breath intake indicator for indicating a flow of air through the chamber in a dispensing direction; and a dispensing connection for connecting to a dispensing device only in a defined rotational position. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 26, 29, 30, 31, 33, 36, 39, 42)
