ABSTRACT:
A powdered medication inhaler is provided which comprises a body having a hollow chamber of substantial height. Powdered medication is transferred from a hopper by a dosing blade having an amperture therein to a transfer station opening into a chamber. In most embodiments of the invention the transfer station is adjacent the upper portion of the chamber, but in one embodiment it is adjacent the lower portion thereof. When the transfer station is adjacent the upper portion of the chamber it includes a pallet or cup on which powdered medication is dropped or blown from the dosing blade. Gas then carries the medication from the cup or pallet into the chamber for inhalation by a patient. In the embodiment in which the transfer station is adjacent the bottom of the chamber compressed gas blows the powder up into the chamber.
