Metered Dose Inhaler type asthma medications are often delivering the medicine too fast that most of the drug sticks at the upper airways and also another risk is the synchronization of the inhaling and spraying which is a difficulty for elder people and children.Just for avoiding these possible disadvantages, there is used a room or a chamber that contains medicine and there is one way flow of atmospheric air when inhaled, thus the speed of medicine particles will be slower for a better effective treatment and the big particles will stick to inner walls of this chamber instead of upper airways, also the timing becomes unimportant when inhaled from inside the chamber. So very user friendly and practical aparatus for the Metered Dose Inhaler user…It has four models with mouthpiece, small, medium and large masks for better compliance of the users. Every part of it can be cleaned at dish washing machine during the economical life time.
