INHALER WITH COMPOSITE POROUS SUPPORT ELEMENT Russian patent published in 2022 - IPC A61M15/00 A61M15/06 

FIELD: medical equipment.

SUBSTANCE: group of inventions relates to medical equipment, namely to a product in the form of an inhaler and an inhaler system. The product contains a case passing along a longitudinal axis from a mouthpiece end to a distal end. The product includes an end element at the distal end and a cavity for a capsule, formed inside the case and passing along the longitudinal axis for a cavity length. The product has an air inlet area between the end element and the cavity for the capsule. The air inlet area has an air inlet and an air passage passing from the air inlet to the cavity for the capsule. The product contains a composite porous support element forming an end of the cavity for the capsule, located further along a stream. The composite porous support element is formed of the first porous material concentrically located around the second porous material. The composite porous support element passes along the longitudinal axis along the length. The first porous material has the first drag resistance, and the second porous material has the second drag resistance. The first drag resistance differs from the second drag resistance. The second porous material forms a central core part, and the first porous material forms an outer peripheral layer surrounding the central core part. The central core part forms a cylinder, and the outer peripheral layer may pass along a length of the central core part. The product has an air channel of a mouthpiece, passing from the cavity for the capsule through the composite porous element to the mouthpiece end. The inhaler system contains a product in the form of an inhaler and a capsule located inside the cavity for the capsule of the product in the form of the inhaler. The capsule contains particles. Particles have a mass-median aerodynamic diameter of 5 micrometers or less, or in a range from 0.5 micrometers to 4 micrometers, or in a range from 1 micrometer to 3 micrometers.

EFFECT: provision of a product in the form of an inhaler, which would be formed of materials forming traditional cigarette configurations, could be assembled at a high speed, would have a shape easy to retain, familiar to a user, and similar to a traditional cigarette, and would be convenient for being used by a consumer.
