Problems solved by technology

[0037] However, in the existing known technology, even if the breathing state during sleep can be easily detected without being hospitalized, it is still impossible to accurately measure the breathing state during sleep.
Moreover, a technology that can take into account the two aspects of simplicity and correctness has not yet been proposed.

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...

Abstract

The invention provides a sleep breath pause judging device, which can capture phonomena of chest motion stopping and belly motion continuing in a breath pause state in a non-contact manner when a person is sleeping and thus accurately judge sleep breath pauses. The judging method by the sleep breath pause judging device comprises the following steps of emitting microwaves to the chest and the belly of an asleep detected person; performing Fourier transform on the microwave Doppler frequency shift signals obtained from the return waves; comparing the frequency components of the fundamental waves and the odd harmonics; and judging whether the asleep detected person has a normal breath state or not based on the comparison result. Thus the breath pause state of the asleep detected person can be accurately judged.

Description

technical field [0001] The present invention relates to a sleep apnea judging device, which monitors the breathing state of a sleeping subject in a non-contact manner, and judges the apnea state that occurs during sleep, that is, the so-called apnea syndrome. Background technique [0002] In recent years, so-called sleep apnea syndrome, which temporarily stops breathing during sleep, has attracted attention as a disease associated with high blood pressure and sleep disturbance. [0003] Sleep apnea syndrome not only aggravates lifestyle-related diseases, but also causes sleepiness and inability to concentrate during the daytime when normal activities are performed due to inability to get enough sleep at night. Since this state will increase the probability of the subject being involved in an accident, early diagnosis and early treatment are required. [0004] Often, the diagnosis of sleep apnea is considered troublesome. The reason is that, for example, hospitalization is ...
