INHALER Russian patent published in 1998 - IPC

FIELD: medical engineering. SUBSTANCE: device has closed chamber with elongated capsule inside, discharge nozzle, means for retaining and means for opening the capsule. Chamber shape allows the capsule to easily rotate about its transverse axis under the action of air flow, come into impact interaction with at least one cavity wall to increase probability of medicine being released from the capsule. Another version of inhaler is provided with eddy flow chamber for receiving the capsule. The capsule is manufactured to enable shaking after its opening in air flow takes place. Specific surface resistance of chamber walls is less than 10¹² Ohm to impart them antistatic properties. EFFECT: low amount of medicinal powder accumulated on the surfaces of air channel walls. 30 cl, 20 dwg
