Problems solved by technology

[0008] Therefore, the above-mentioned methods for judging apnea all need to rely on PSG, which is complex and cumbersome and has extremely low user experience, and can only be detected and checked in a hospital environment, and cannot be applied to daily life environments such as home or business travel.

Embodiment Construction

[0059] see figure 2 In order to solve the problems in the prior art, the present invention provides a system for judging apnea during sleep, which includes a piezoelectric sensor 10, an A / D conversion module 20 and a processor 30 connected in sequence.

[0060] The piezoelectric sensor 10 is used to collect the simulated sleep breathing signal of the subject during sleep in real time, and transmit it to the A / D conversion module 20;

[0061] The A / D conversion module 20 is used to convert the sleep breathing analog signal into a sleep breathing digital signal, and transmit it to the processor 30;

[0062] The processor 30 is used to process the sleep breathing digital signal to obtain a waveform diagram of a respiratory rate and a waveform diagram of a pulse rate, and analyze the waveform diagram of a respiratory rate and a waveform diagram of a pulse rate to obtain a judgment conclusion on whether apnea occurs during sleep.

[0063] see figure 1 , the system realizes the m...

Abstract

The invention relates to a method and a system for judging apnea during sleep. The method comprises the following steps: step 1: acquiring a sleep breathing signal of a testee during the sleep in real time; step 2: processing the sleep breathing signal to obtain a breathing rate waveform diagram and a pulse waveform diagram; and step 3: analyzing the breathing rate waveform diagram and the pulse waveform diagram to determine whether the apnea happens during the sleep. Therefore, by virtue of the above solution, the determination of the sleep apnea is realized without contacting the testee, the radiation is avoided, and the detection result is accurate; and moreover, convenience in carrying is realized, the use is convenient and rapid, the test of the apnea and the use for examination when a user is at home or in an environment of the business travel can be satisfied, and the consumption of time and money can be reduced.

Description

technical field [0001] The invention relates to a sleep apnea detection technology suitable for daily life environment, in particular to a sleep apnea detection technology which monitors breathing, pulse and other vital signs during sleep in a non-contact manner and judges the apnea state during sleep. Periodic apnea judgment system. Background technique [0002] Sleep Apnea Syndrome—Sleep Apnea Syndrome (SAS) is a common disease that occurs during sleep. Specifically, it refers to repeated episodes of apnea for more than 30 times or more during 7 hours of sleep per night. A sleep apnea-hypopnea index (usually abbreviated as AHI) ≥ 5 times / hour and accompanied by clinical symptoms such as lethargy. SAS has become an invisible killer that endangers human life. According to statistics, SAS patients diagnosed and treated in developed countries account for 20% of the total number of patients, and our country accounts for 2%. The main reason is that the standard monitoring meth...
