DRY POWDER INHALER AND INHALER SYSTEM Russian patent published in 2022 - IPC A61M15/00 

FIELD: tobacco industry.

SUBSTANCE: group of inventions relates to a dry powder inhaler and to an inhaler system for dry powder delivery. The dry powder inhaler contains an inhaler case passing from a mouthpiece end to a distal end and containing a mouthpiece part detachably connected to a distal end part and passing between the mouthpiece end and the first mated end. The specified distal end part passes between the second mated end and the distal end. The mouthpiece part contains a cavity for a capsule, formed inside the first mated end, and a mouthpiece air channel passing from the mouthpiece end to the cavity for the capsule. The distal end part contains an element for airflow passage, located inside the distal end part and passing for a longitudinal length defined between the first transverse end and the opposite second transverse end. The element for airflow passage passes to the cavity for the capsule and contains: an airflow channel passing for a longitudinal length of the element for airflow passage, which is not parallel to the longitudinal axis and directs inlet air to the cavity for the capsule; and resealed membrane forming a section of the mentioned first transverse end or the second transverse end and made with the possibility of being resealed, when extracting a piercing element from resealed membrane.

EFFECT: simplification of replacement of inhaler components, and provision of multiple use of the installed capsule.
