Device in particular and inhalating device for treating the lung and the respiratory tracts

In an inhaling and exhaling device for treating the lung and respiratory tracts of humans and animals, said device comprising:

• a housing having a gas chamber therewithin and an opening outside said chamber extending to the atmosphere;
• an atomizer connected to said chamber for supplying gas and atomized medication to said chamber;
• a source of gas under pressure above atmospheric pressure connected to said atomizer for supplying gas to said atomizer;
• and
• mouthpiece means on said housing and having a passageway leading to said chamber whereby inhalation gas passes along a path extending from said chamber and out of said mouthpiece means and exhalation gas passes along a path extending from said mouthpiece means toward said chamber;
• wherein the improvement comprises:
• valve means periodically operable from externally of said housing and in said path extending from said mouthpiece means toward said chamber, said valve means being alternately operable from an open position which permits gas to flow along said path from said mouthpiece means toward said chamber and to a closed position which prevents the flow of gas along said path from said mouthpiece means toward said chamber and said valve means comprises a spent air flue extending from said chamber to adjacent said opening, a valve for opening and closing said spent air flue and valve actuating means connected to said valve and mounted on said housing;
• and
• a control unit connected to said valve means for periodically operating said valve means from its open position to its closed position, and vice versa, independently of the gas pressure at said mouthpiece means
• whereby the flow of gas through said mouthpiece means is periodically interruptible while the human or animal is exhaling.
