Inhalation device

Abstract

An inhalation device 10 includes: accommodation parts 11 that each accommodate, in a coil shape, a belt-like blister strip 20 in which a powder medicine is sealed between a sheet 24 and a plurality of blister pockets 21; drive units 12 that each pull out the blister strip 20 from the corresponding accommodation part 11; and opening parts 13 that each open the pulled-out blister strip 20 and allowing the medicine to be inhaled from an inhalation part 18. The drive units 12 each include a winding part 25 that winds the sheet 24 released from the blister pockets 21. The winding part 25 includes: a base portion 31 that is rotationally driven; an arm support portion 32 that extends outward in the radial direction from the base portion 31; and an arm portion 30 that extends in an arc shape and in a cantilever shape in the circumferential direction of the base portion 31 of the arm support portion 32, and is elastically deformed so as to be inclined in the radial direction of the base portion 31 with respect to the arm support portion due to winding of the corresponding sheet 24 to thereby impart tension to the sheet 24.
