Abstract: The aerosol generator of an inhalation therapy device according to a preferred embodiment of the invention continuously produces an aerosol at a generation rate of about 0.2 ml/min to about 1.5 ml/min, preferably 0.4 ml/min to about 1.2 ml/min and the mixing chamber has a volume of about 60 ml to about 150 ml, preferably about 80 ml to about 120 ml, and even more preferably about 90 to about 110 ml.

Abstract: A dispenser for hair building solids can be readily operated and aimed with one hand. A bulb that provides air for suspending the solids is located directly on top of a dispenser body. The bulb can be depressed by a single finger when the device is held in one hand. When the compressed air exits the bulb, it follows a direct straight downward pathway to the surface of the hair building solids. Air exiting the bulb passes through an air injecting orifice that is directed towards the surface of a mass of hair building solids suspending the solids within the turbulently pressurized container, which solids are then directed smoothly by the domed undersurface of the dispenser body into the straight bore of a short nozzle. The path followed by the solids is without bends thereby avoiding clogging.
