TH784A - Inhaler for determining the dosage of the drug - Google Patents

Abstract

Inhaler for powder which is activated by the flow of air generated by inhalation and with the purpose of exhalation. The solid substance is small in microns and is pharmacologically active. The inhaler consists of 2 nozzles, 1 air ducts, 6 dosing units used, 10 contains storage rooms, 5 for active ingredients. Partition membranes with holes 4 retainer 9 for perforated membranes. The dosing route 8 was to deliver the active substance into the membranes 4 and the membranes replacement route 4 that contacted the storage chamber 4. As membranes 4 and the second The membranes section 4 is positioned in the air duct 6 to provide air Was breathed in, patent medicine
