A device for mechanically generating inhalable active substance particles from a consolidated medication supply and for conveying the active substance particles into the respiratory tract, wherein, in order to generate the active substance particles, there is a drivable face mill against which the front of a medication supply in the form of a ring- shaped body can be pressed, whereby the ring-shaped body forms the beginning of an inhalation tube ending in a mouthpiece and in that the housing surrounding the ring-shaped body and the face mill is provided with air inlet openings in the blade area of the face mill and said air inlet openings, together with the depressions located between the blades and the inhalation tube, form an air channel leading to the mouthpiece.

Un dispositif de génération mécanique de particles inhalables de substances actives à partir d'un bloc consolidé de médicament, et d'amenée des particules de substances actives dans les voies respiratoires, se caractérise par le fait de comprendre une fraise en bout entraînable qui produit les particules de substances actives et contre laquelle la face frontale d'un bloc de médicament en forme de corps annulaire peut être pressée. Le corps annulaire forme le début d'un tube d'inhalation qui finit dans une embouchure. Le boîtier qui renferme le corps annulaire et la fraise en bout est pourvu d'ouvertures d'entrée d'air dans la zone des bords tranchants de la fraise en bout. Ces ouvertures forment avec les dépressions situées entre les bords tranchants et avec le tube d'inhalation un canal d'air qui mène jusqu'à l'embouchure.
