Patent ID: 8734370

Claim:
A device for clearing mucus from the pulmonary system of a human, comprised of: a pneumatic pressure generator for producing a time-varying pressure output; a pressure control means whereby the temporal characteristics of said time-varying pressure output are regulated to conform to a desired pressure profile; a pressure selection means whereby said pneumatic pressure generator is sequentially commanded to produce, over successive time intervals, and in an arbitrary order, a specific pressure variation including: (a) a vibratory-pressure variation having a frequency spectrum substantially contained within the range 5 Hz to 20 Hz; and (b) a constrictive-pressure variation having a frequency spectrum substantially contained within the range 0 Hz to 5 Hz; pressure channeling means, whereby said vibratory-pressure variation is channeled to a first pressure receiver configured to be in communication with an upper thorax of said human, and said constrictive-pressure variation is channeled to a second pressure receiver configured to be in communication with a lower thorax of said human; and a processor for implementing said pressure control means, said pressure selection means and said pressure channeling means.
