  • Patent number: 6881398
    Abstract: A therapeutic dry powder preparation and a method of administering such a preparation are disclosed for effectively de-aggregating and dispersing into air a dose of medication powder in an administration the dose to a user. The present dry powder preparation and method do not require other sources of energy besides the power of an inhalation effort by a user to produce a very high degree of de-aggregation and efficient dispersal into air of the dry powder medication dose. Utilizing an effort of sucking air through a nozzle, the particles of the therapeutic powder dose, made available to the nozzle, are gradually de-aggregated and dispersed into a stream of air entering the nozzle.

  • Patent number: 5660169
    Abstract: The invention relates to a disposable breath-actuated inhaler comprising a housing forming an air flow path open at both ends, wherein one end forms an air inlet and one end forms an air outlet. The housing includes a compartment for storing a pharmaceutical powder to be inhaled which is located close to the air inlet and covered by a thin foil which seals the compartment in an airtight way. The foil can be removed from the compartment from outside the housing. Additionally, the housing has a constriction adjacent the powder compartment such that a turbulent air stream will be obtained at the constriction upon inhalation which will lift the powder out from the compartment and mix the powder into the air stream.
