Embodiment 1
[0141] Below, use Figure 1 to Figure 11 The first embodiment of the sleep apnea determination device will be described in detail.
[0142] [principle description of the present invention: Figure 9 , Figure 10 , Figure 11 ]
[0143] First, use Figure 9 ~ Figure 11 The principle of signal detection realized by the microwave Doppler sensor mounted on the sleep apnea determination device will be described.
[0144] Figure 9 is a block diagram representing the microwave Doppler sensor and the subject. Figure 10 , Figure 11 This is a waveform diagram schematically showing a signal waveform detected by a microwave Doppler sensor.
[0145] exist Figure 9 Among them, 31 is a microwave transmitter, 32 is a microwave receiver, and 33 is a microwave demodulator, which together constitute the microwave Doppler sensor 3 .
[0146] 10 is a subject, and 10a is an upper body portion composed of the chest and abdomen of the subject 10, hereinafter referred to as the chest and...
Embodiment 2
[0319] [Structure description of the sleep apnea determination device: Figure 12 ]
[0320] The following uses Figure 12 A second embodiment of the sleep apnea determination device will be described.
[0321] As the sleep apnea determination device 100 of the second embodiment, an abnormality measurement detection unit 50 is added to monitor whether the function of the sleep apnea determination device 1 is normal in the chest and abdomen state detection device 5, so as to improve sleep apnea. Determine the reliability of the action.
[0322] Figure 12 It is a functional block diagram showing the partial structure of the sleep apnea determination device 100 , in which only components different from those in the first embodiment are shown: the chest and abdomen state detection device 5 a , the breathing type determination unit 6 and the notification device 7 .
[0323] Input the Fourier transform result Mf to the abnormal measurement detection part 50 of the chest and abd...
