Inhalation device

Abstract

The present disclosure provides an inhalation device including: a storage portion for storing a strip-shaped blister strip in a coiled form, where a powdered medicament is sealed between a sheet and multiple blister pockets; a drive portion for drawing out the blister strip from the storage portion; and an opening portion for opening the drawn-out blister strip so that the medicament can be inhaled from an inhalation portion; the drive portion includes a winding portion for winding the sheet peeled from the blister pockets; the winding portion includes: a base portion that is rotationally driven; an arm support portion that extends radially outward from the base portion; and an arm portion that extends in an arc shape in a circumferential direction of the base portion of the arm support portion and in a cantilever beam shape, and that is elastically deformed so as to be inclined radially toward the base portion relative to the arm support portion by the winding of the sheet, thereby imparting tension to the sheet.
