Abstract

Patente de Invenção: <B>"INALAçãO DE ATIVOS DE AEROSSOL"<D> Processo de redução da inalação de partículas ou de gotículas transportadas pelo ar / respiráveis tendo um diâmetro de menos do que 10 micrómetros, produzidas por atomização de gotículas líquidas a partir de um dispositivo de atomização, processo esse que compreende conferir uma carga unipolar às gotículas líquidas por carregamento de dupla camada, durante a atomização das gotículas líquidas a partir de um dispositivo de atomização, a carga unipolar estando em um nível tal que as ditas gotículas tenham uma razão de carga para massa de pelo menos ± 1 x 10^ -4^ C/Kg, por meio do que pelo menos 10% em volume das partículas ou gotículas respiráveis transportadas pelo ar tendo um diâmetro de menos do que 10 micrómetros, na vizinhança da boca, do nariz ou do trato respiratório superior, não entram nos pulmões.Invention Patent: <B> "INHALATION OF AEROSOL ASSETS" <D> Process for reducing the inhalation of airborne / respirable particles or droplets having a diameter of less than 10 micrometers, produced by atomizing liquid droplets from of an atomization device, a process that comprises giving a unipolar charge to the liquid droplets by double layer loading, during the atomization of the liquid droplets from an atomization device, the unipolar charge being at a level such that said droplets have a load to mass ratio of at least ± 1 x 10 ^ -4 ^ C / Kg, whereby at least 10% by volume of the airborne respirable particles or droplets having a diameter of less than 10 micrometers in the neighborhood of the mouth, nose or upper respiratory tract, do not enter the lungs.
