Abstract
A device for detecting sleep apnea comprising an abdominal movement sensor, an oxygen saturation sensor, a data acquisition unit configured to acquire an abdominal movement time-series from the abdominal movement sensor and an oxygen saturation time-series from the oxygen saturation sensor, and a sleep apnea detection unit configured to determine sleeping interval, Apnea-Hypopnea events, and an Apnea-Hypopnea Index.
Claims27
A device for detecting sleep apnea in a patient, the device comprising an abdominal movement sensor for the patient, an oxygen saturation sensor for the patient, a data acquisition unit and a sleep apnea detection unit, wherein a first signal connection connects the abdominal movement sensor to the data acquisition unit and a second signal connection connects the oxygen saturation sensor to the data acquisition unit, the data acquisition unit being configured to acquire an abdominal movement time-series from abdominal movement sensor and an oxygen saturation time-series from the oxygen saturation sensor and to provide the abdominal movement time-series and the oxygen saturation time-series to the sleep apnea detection unit, the sleep apnea detection unit being configured to determine an Apnea-Hypopnea Index for the patient based on the abdominal movement time-series, the oxygen saturation time-series and at most one time-series from at most one additional sensor of different type.

11-14. (canceled)
A method for detecting sleep apnea in a patient, the method comprising at least the following steps:
- attaching an abdominal movement sensor, an oxygen saturation sensor and at most one additional sensor of different type to the patient;
- acquiring an abdominal movement time-series with the abdominal movement sensor, an oxygen saturation time-series with the oxygen saturation sensor and a time-series from the at most one additional sensor of different type with a data acquisition unit while the patient sleeps;
- and
- determining an Apnea-Hypopnea Index for the patient based on abdominal movement time-series, the oxygen saturation time-series and the time-series from the at most one additional sensor of different type with a sleep apnea detection unit.
