RinoFlow is a compressor-micronizer chamber system specifically designed for the treatment of affections of the upper respiratory tract. It generates a jet of micronized watery particles of large diameter (<18 micron) which enter the nasal cavities, the rhinopharynx and the pharynx, soften mucus and catarh and remove it, thanks to the pressure on mucous membranes. The micronizer chamber of the RinoFlow is composed of an inside bell and an outer shell. In the space between them, a specific secrion allows collection of drainage liquid for possible clinical analysis. Two different treatment steps can be selected (position 1 and 2) allowing a gentle or a stronger wash of the nasal acitvities and of the rhino-pharynx.
