  • Patent number: 12232862
    Abstract: The present invention may provide a device and a method for detecting and diagnosing sleep apnea, which can accurately determine an apnea state by: extracting a respiration signal of an examinee from a received signal which is a reflection of an impulse signal emitted from at least one IR-UWB radar; setting a threshold value for determining an apnea state from changes in the deviation and interval between peaks of the extracted respiration signal; and comparing the set threshold value with the deviation between the peaks. Therefore, the sleep apnea can be accurately detected and diagnosed using a non-contact/noninvasive method, and thus inconvenience felt by the examinee can be reduced.
