The present invention relates to an improvement of the mouthpiece of a dry powder inhalation device wherein the medicament is packed in the blisters of single dose blister strips. According to the invention a portion of the air which enters the mouthpiece does not pass through the powder containing blister, but follows an alternative path through the mouthpiece, enabling therefore the modification of the resistance of the device in a simple and cost effective manner.
L'invention concerne une amélioration apportée à l'embout buccal d'un dispositif d'inhalation de poudre sèche dans lequel un médicament est conditionné dans les alvéoles de plaquettes alvéolées monodoses. Selon l'invention, une partie de l'air qui pénètre dans l'embout buccal ne passe pas dans l'alvéole contenant la poudre, mais suit un chemin alternatif dans l'embout buccal, ce qui permet de modifier la résistance du dispositif de manière simple et économique.
