  • Publication number: 20090020122
    Abstract: A respirator device for use in treating obstructive sleep apnea is described, with a pressure generator for generating an artificial atmosphere having a treatment pressure, with a pressure regulating device for controlling the pressure generator, and with a respiratory tube with a breathing mask for supplying the artificial atmosphere generated by the pressure generator to a patient, which is characterized in that it has a control mechanism for the continuous determination of a pressure loss occurring over an airway resistance in the airways of the patient, and for the essentially proportional adjustment of the pattern of treatment pressure to the pattern of the determined pressure loss. The use of a respiratory device of this type for the treatment of sleep apnea substantially decreases the strain on the respiratory musculature of the patient, makes the course of treatment more pleasant, and decreases potential secondary effects of the treatment.

  • Patent number: 7182082
    Abstract: In order to treat snoring and obstructive sleep apnea, the inner respiratory tract is subjected to atmospheric pressure and the outer surrounding area of the respiratory tract is subjected to artificial low-pressure, the difference between the inner atmospheric pressure and the outer low-pressure remaining constant. The respiratory therapy device consists of a pressure stable hollow body which surrounds the human body while keeping free the natural respiratory opening. Set hollow body forms the low-pressure chamber (7) is connected to a suction pump (3) by a suction tube (2). The invention method and respiratory therapy device make it possible to breathe in a free atmosphere.
