Apnea state detection device, apnea state avoidance system, apnea state detection method and apnea state detection device operating method

摘要

PROBLEM TO BE SOLVED: To detect an apnea state at a low cost with a simple structure as compared with a conventional technique. An apnea detecting device is provided through a body surface on a blood vessel of a human body, detects a pressure change of a pulse wave flowing in the blood vessel, and measures the voltage value of a blood vessel pulse wave signal. Based on a blood vessel pulse wave signal, an apnea state detection device comprising a control means for detecting the apnea state of the human body, the control means, the maximum peak value of the envelope of the blood vessel pulse wave signal and The time average value calculated by averaging the average value of the minimum peak values over a predetermined time is set as a threshold value, the signal level of the blood vessel pulse wave signal is compared with the set threshold value, and the blood vessel pulse wave is set. When the signal level of the signal is below the set threshold value, the human body is detected as an apnea. [Selection diagram] Figure 1
