A new dry powder inhaler is developed as a pulmonary medicine delivery device for dispersing precise tiny dosages (10 μg-50 mg) of pure carrier-free ultra-fine powdered medicament (<5 μm aerodynamics particle size) into a patient's lung. The powder is drawn from the blister cell and dispersed through an outlet tube assisted by two air streams. The first air stream goes through a the blister cell from its upstream side, to significantly fluidize the medicament in the dose to flow upward. The second one extracts the fluidized powder from downstream of the blister cell for further deagglomeration and dispersion of the medicament powder by shear force. The rotating multi-dose blister can hold up to 60 doses, which are pre-metered with pure ultra-fine powdered medicament. So that it has higher drug loading capability in small volumes, compared to most current dry powder inhalers, which usually use some excipient. The inhaler efficiently disperse the aerosolized medicament in the air stream to the deep interior of patient's lung. The fine particle fraction (<4.7 μm) is reported to reach as high as 80% using this inhaler.

A method of creating small particles by a technology referred to here as “violent focusing” is disclosed, along with devices for generating such violent focusing. In general, the method comprises the steps of forcing a first fluid out of an exit opening of the feeding channel to create a fluid stream. The exit opening is positioned such that the fluid flowing out of the channel flows toward and out of an exit orifice of a pressure chamber which surrounds the exit opening of the feeding channel, and is filled with an atomizing fluid. An atomizing fluid such as a gas is directed towards the first fluid stream in approximately orthogonal directions and surrounding the circumference of the first fluid stream from all sides. The first fluid flow is broken into particles which have dimensions which are smaller than the dimensions of this fluid stream.

A non-burning type flavor inhaler includes an aerosol source that generates an aerosol; an atomizer that atomizes the aerosol source without burning; a power source that supplies power to the atomizer; a light-emitting element; and a control unit that controls the light-emitting element. The control unit controls the light-emitting element in a first light-emitting mode in a puff state inhaling the aerosol, and controls the light-emitting element in a second light-emitting mode different from the first light-emitting mode in a non-puff state not inhaling the aerosol. The second light-emitting mode changes according to a number of puff actions for inhaling the aerosol.

The present invention provides an improved means of treating tracheobronchitis, bronchiectasis and pneumonia in the nosocomial patient, preferably with aerosolized anti gram-positive and anti-gram negative antibiotics administered in combination or in seriatim in reliably sufficient amounts for therapeutic effect. In one aspect, the invention assures this result when aerosol is delivered into the ventilator circuit. In one embodiment the result is achieved mechanically. In another embodiment, the result is achieved by aerosol formulation. In another aspect, the invention assures the result when aerosol is delivered directly to the airways distal of the ventilator circuit. The treatment means eliminates the dosage variability that ventilator systems engender when aerosols are introduced via the ventilator circuit. The treatment means also concentrates the therapeutic agent specifically at affected sites in the lung such that therapeutic levels of administrated drug are achieved without significant systemic exposure of the patient to the drug. The invention further provides a dose control device to govern this specialized regimen.
