Non-invasive/non-contact type sleep apnea detection and diagnosis apparatus and method using IR-UWB radar

摘要

The present invention extracts the respiration signal of the examinee from the signal signal received by reflecting the impulse signal radiated from at least one IR-UWB radar, and determines the apnea state from the deviation between the peaks of the extracted respiration signal and the change in the peak interval It is possible to provide an apparatus and method for detecting and diagnosing sleep apnea that can accurately determine an apnea state by setting a threshold value for apnea and comparing the set threshold value with a deviation between peaks. Therefore, it is possible to accurately detect and diagnose sleep apnea in a non-contact/non-invasive method, thereby reducing the discomfort of the examinee.
