An inhaler that utilizes vibration to facilitate suspension of powder into a gas is provided. One embodiment of the inhaler includes a piezoelectric vibrator for vibrating the powder. A controller is provided for controlling supply of actuating electricity to the vibrator so as to cause the powder to vibrate in such a way as to optimally suspend at least a portion of the powder into the gas. The controller may include a user-actuable control for permitting the user to select the vibration frequencies and/or amplitudes for optimally suspending in the gas the type of powder currently being used in the inhaler.
L'invention concerne un inhalateur (220) qui met en oeuvre des vibrations afin de faciliter la suspension de la poudre dans un flux d'air. Selon une réalisation de l'invention, l'inhalateur comprend un vibrateur piézo-électrique (254) destiné à faire vibrer la poudre. Un régulateur est prévu pour réguler l'alimentation en courant du vibrateur afin de provoquer des vibrations dans la poudre de façon à ce que celle-ci se désagrège et que ses particules se séparent selon leur taille. Les particules de poudre sont alors maintenues en suspension dans le flux d'air par un dispositif électrostatique (232).
