Desaglomerador for dry powder Inhaler Breath actuated, a dry powder Inhaler and Method for deagglomeration of dry powder.

摘要

It provides a desaglomerador to be used with a dry powder Inhaler Breath Actuated to decompose Aggregates and micronize particles before dry powder inhalationOn the dry powder by a patient to use the Inhaler.The desaglomerador includes an inner Wall defining a Vortex Chamber which extends along an Axis from a First end to a Second End.A dry powder Supply Hole, an Inlet hole and an outlet Hole.The supply hole is located at the first end of the Swirl Chamber for the purpose of providing Fluid Communication between a Passage of release of a dry powder InhalerAnd the first end of the Vortex Chamber.The Inlet is located on the Inner Wall of the Swirl Chamber adjacent the first end of the Vortex Chamber and provides Fluid Communication between an outer regionThe desaglomerador and the Vortex Chamber.The Outlet provides Fluid Communication between the second end of the Vortex Chamber and a region outside the desaglomerador,Thus a slight pressure induced by Breathing in the Air Exit Hole causes the Flow to the Vortex Chamber through the supply Hole dry powder and Orifice entrAda.The Air flows Collide with the Wall of the Chamber and Vortex before leaving the exit Orifice.So that the Dust transported in the Air Flow decomposes and Micronized.The desaglomerador also includes openings in the first end of the Vortex Chamber to create additional Dust transported Collisions and impacts.
