摘要:
A breathing-actuated dry powder inhaler comprising: a dust container (151) having an inner surface that defines an inner volume and that promotes the flipping of a flow that enters the inner volume, at least one port (119) air inlet to allow ambient air to flow to the interior volume, at least one dispensing port (127) having a flow direction that allows the flow of dust-containing air to exit or flow from the interior volume; and a duct (140) having an air inlet (110) at one end and an outlet (135) that is part of a nozzle (130) at its other end; the at least one dispensing port (127) that opens to the conduit (140) from a lower side thereof; the air inlet port (119), the at least one dispensing port (127) and a nozzle region of the duct that forms a first air flow path through the container to fluidize the powder therein; the conduit (140) defining a second air flow path to the nozzle by circumventing the dust container (151); wherein when the breathing-actuated dry powder inhaler is in use, the air flow along the duct (140) impacts the air flow and the powder into the duct from at least one dispensing port (127) and it provides a shear force that changes the direction of flow of the dust particles as they leave said at least one distribution port and promotes the de-agglomeration of the dust particles.Un inhalador de polvo seco accionado por la respiración que comprende: un recipiente (151) de polvo que tiene una superficie interior que define un volumen interior y que promueve el volteo de un flujo que entra al volumen interior, al menos un puerto (119) de entrada de aire para permitir que el aire ambiente fluya al volumen interior, al menos un puerto (127) de dispensación que tiene una dirección de flujo que permite que el flujo de aire que contiene polvo salga o fluya del volumen interior; y un conducto (140) que tiene una entrada (110) de aire en un extremo y una salida (135) que forma parte de una boquilla (130) en su otro extremo; el al menos un puerto (127
