Mist inhaler

An inhaler apparatus by which a vapor containing medication is formed to provide a cloud of very fine mist that can be inhaled deep into a patient's lungs, said apparatus includes an enclosure that forms a cloud chamber within which a cloud of medication and vapor can be formed;

• a liquid containing chamber connected to said cloud chamber, a suitable heating element, including means by which said heating element is energized to heat at least some of any liquid contained within said liquid containing chamber, and a pump means for reducing the pressure within said cloud chamber to a value that enhances the vaporization of the liquid to thereby form a cloud within said cloud chamber;
• means introducing a powdered medicament into said cloud chamber;
• and means including a mouthpiece by which the contents of the cloud chamber flows therethrough:
• whereby, a cloud is formed by the provision within the cloud chamber of the proper pressure, moisture content, temperature, and a powdered medicament that provides the medication and which is dispersed within the cloud chamber to seed the vaporized liquid and form a cloud.

A method of forming a cloud of vapor and medicine that can be inhaled to treat the lungs, comprising the steps of:

• isolating a liquid and evaporating a quantity of the liquid within an enclosure while adjusting the pressure within the enclosure to a value that enhances the subsequent formation of a cloud;
• arranging a quantity of treatment medicine that is in the form of a finely divided powder;
• said quantity of powder is selected to provide a dose of medicine for ones lungs;
• dispersing said dose of medicated powder into the evaporated liquid to seed the contents of the enclosure and thereby enhance the formation of a cloud therewithin;
• connecting a mouthpiece to the enclosure;
• and using the mouthpiece to translocate the formed cloud into the lungs;
• and further including the steps of:
• placing a one way check valve between a pump means and the enclosure to prevent subsequent loss of the medicated cloud.
