  • Patent number: 9295804
    Abstract: A mouthpiece for controlled delivery of a breathing gas including oxygen, preferably an increased ratio of oxygen with respect to ambient air, to the respiratory tracts of a user which includes a valve having two modes; a closed default mode, which substantially impedes any flow of the breathing gas through the valve; and an active open mode, which allows for a substantial flow of the breathing gas through the valve, wherein the open mode can be activated by the user manipulating the valve with his/her mouth. Such a valve may be used in a device for delivery of breathing gas and in an apparatus for controlled delivery of the breathing gas to the respiratory tracts of a user. A method for controlled delivery of the breathing gas to the respiratory tracts of a user may include operating the valve.

  • Patent number: 8157743
    Abstract: A device and a method for evaluating a signal that can indicate the respiration of a person, particularly suitable for examining a patient with respect to the occurrence of sleep-related breathing disturbances. In one example, a device for evaluating a signal indicative of the temporal course of the respiration of a patient, in particular a respiratory flow signal, includes an electronic evaluation program or circuitry which is configured in such a manner that it evaluates the signal by continuously generating intermediate evaluation results for short signal periods and for longer signal periods being parallel thereto, and performs an identification of respiratory patterns in the time signal or in specific time periods on the basis of the position of the intermediate evaluation results of the short signal periods relative to the intermediate evaluation results of the longer signal periods.

  • Patent number: 8104471
    Abstract: The invention is directed to an apparatus and a method for surveying and analyzing flow signals that can be picked up by means of flow measuring arrangements in the flow through breathing gas supply systems, in particular CPAP devices, air humidifiers, breathing gas lines, and breathing masks. One aspect of the invention is to furnish ways to increase the reliability of flow signals. In one embodiment, there is provided a device for evaluating a flow signal, picked up from a line provided for carrying breathing gas, having an electronic measurement data processor. The measurement data processor is configured such that it subjects the measurement data detected to a time-frequency-amplitude (TFA) series analysis and generates recordings, by which for the flow signal, the amplitude value of the frequencies contained is apparent.
