Abstract: Disclosed are an atomizer for a fluid and a method for conveying and atomizing a fluid. The atomizer includes: a cartridge for accommodating multiple doses of the fluid; a delivery mechanism movable from an initial position to a tensioning position for withdrawal of a medication dosage of the fluid from the cartridge when the atomizer is tensioned, and movable from the tensioning position to the initial position for atomization of the medication dosage of the fluid when the atomizer is activated; a pre-determined amount of the fluid is atomized by a temporary rebound motion of the delivery mechanism during its movement from the initial position to the tensioning position, and the medication dosage is a single medication dose, and the pre-determined amount is less than the medication dosage.

Abstract: Disclosed is an inhalation device, which, by means of a simplified structure, reduces the manufacturing difficulty and cost while ensuring the use effect. In the inhalation device of the present application, a filter member closely fits a capsule insertion port, and when a mouthpiece is snap-fitted on a deck, a mesh portion is integrally located in a capsule chamber. Therefore, when pharmaceutical powder is inhaled, airflow can better pass through the mesh portion under the action of a negative pressure to flow in an ideal flow direction, thereby ensuring effective inhalation of the pharmaceutical powder.

Abstract: A pharmaceutical inhalation aerosol and a preparation method therefor. The preparation method comprises the following steps: (1) mixing glycopyrronium bromide coarse powder with indacaterol fine powder, or glycopyrronium bromide coarse powder with indacaterol coarse powder, or glycopyrronium bromide fine powder with indacaterol coarse powder in proportion to obtain a glycopyrronium bromide and indacaterol mixture; (2) micronizing, by a crushing device under pressure, the glycopyrronium bromide and indacaterol mixture prepared in step (1) to obtain a micronized glycopyrronium bromide and indacaterol mixture; and (3) adding the micronized glycopyrronium bromide and indacaterol mixture prepared in step (2) to an aluminum can, performing valve sealing, and filling with a propellant.
