Abstract

<B>"DISPOSITIVO DE INALAçãO"<D>. A presente invenção se refere a um inalador de pó para administração de pó por meio de inalação, compreendendo uma câmara (58) que inclui um elemento de base (12) e um elemento de parede periférica (48), em que a câmara (58) inclui uma primeira entrada (36), através da qual uma primeira corrente de ar contendo pó é quando em uso extraída por inalação por um usuário e uma pluralidade de segundas entradas (66, 67, 68, 69, 100), na junção entre o elemento de base (12) e o elemento de parede periférica (48), através das quais uma pluralidade de segundas correntes de ar, de um combinado fluxo menor que a primeira corrente de ar, é quando em uso extraída por inalação pelo usuário, de modo a minimizar a retenção de pó na junção entre o elemento de base (12) e o elemento de parede periférica (48).
