ABSTRACT:
An inhaler capable of administering powdered medicaments contained in a capsule. It is formed by a compartment housing the capsule, inside the cover or the body of the inhaler, and a cutting element, inside the same cover or the body. Said element cuts or perforates the capsule, releasing the substance it contained. The powder falls into a grid reservoir below that holds the pieces of the case end lets only the powder pass through. Once the capsule is inserted into the compartment, it will be sufficient to activate the cutting device, then place the mouthpiece into the mouth and breathe in, so that the powdered substance dispersed into the chamber can reach the lungs. Said inhaler may be equipped with disposable accessories to be placed into the mouth, otherwise may be used with specific accessories for inhaling the substances also by the nose.
