Abstract
A device is implemented as a functional patch, for measuring sleep apneas, which device includes: an acoustic sensor for measuring respiration and snoring noises; an optical sensor for measuring a saturation of oxygen in the blood of a human; and an adhesive patch which carries the acoustic sensor and the optical sensor. Analysis of the measuring signals and display of the sleep apneas are alternately performed in the functional patch or in an external unit, to which the data are transmitted wirelessly.

12. A method for measuring sleep apneas using an acoustic sensor and an optical sensor, comprising:
-
a) performing an optical calibration measurement; b) performing first optical measurement of first measured values at a first wavelength to ascertain a blood oxygen concentration; c) performing second measurement of second measured values at a second wavelength to ascertain a blood oxygen concentration; d) performing an acoustic measurement of third measured values to ascertain a respiration; and e) transmitting the measured values or values of the blood oxygen concentration and values of the respiration; wherein the method steps a) through d) are performed in arbitrary sequence. - View Dependent Claims (13, 14, 15)
