A device for flow rate limitation at low differential pressures, particularly for limiting the volumetric inhalation flow during inhalation of therapeutic aerosols, consists of a housing including an aspiration orifice , an inhalation orifice and a flow passage disposed therebetween. The flow passage has a flat elongate cross-section with flexible large-area walls having a cross-sectional area adapted to be reduced, as a function of the differential pressure prevailing between the inhalation orifice and the aspiration orifice, as well as of the flexibility of the material of the walls, to a size appropriate for a predetermined volumetric maximum inhalation flow.

Method and an apparatus for providing a constant medicine dose for an inhalic application at low inhalic flow

An inhalation device has a container for an aerosol volume inhaled via a channel and a mouthpiece , the container being located within a housing . The aerosol, in particular vitamin A, is introduced from a cartridge into the interior of the container via a nebulizer . The breath flow in the inhalation device is controlled via a control means that keeps the inhalation flow essentially constant during the entire inhalation period.

Inhalation device

In a device for separating the particle size spectrum of a polydisperse aerosol comprising a housing including an inlet part, a guide part, an outlet part, a nozzle insert and a separation insert, all parts are axially symmetrical and joined by centering fits so that they are easy to manufacture and can easily be assembled and also replaced. The parts are so fitted together that they are automatically centered during assembly while providing for the properly sized aerosol and air supply and particle fraction extraction channels.
