Sätt och anordning för att genom skifte av polaritet styra depositionen av inhalationspartiklar till bestämd nivå i andningsapparaten

摘要

Inhaled particles and the inhaler are given the same polarity as the natural charge of the air passage surfaces. A method for increasing and regulating particle deposition during inhalation comprises imparting the particles and inhaler with the same polarity as the natural charge of the air passage surfaces.
