Wearable sleep monitor and monitoring method

Abstract

The invention provides a wearable sleep monitor and a monitoring method. In one embodiment, the wearable sleep monitoring method comprises the following steps: step a): collecting blood oxygen saturations of a testee in preparation for sleep and during sleep, and acquiring a blood oxygen saturation parameter value; step b) in the sleeping process, when the blood oxygen saturation parameter value is reduced and the reduction maximum value is greater than or equal to a first threshold value, determining that small awakening occurs, and when the reduction duration time (D1) is greater than or equal to 10 seconds, determining that sleep apnea/hypopnea occurs once; step c), collecting electroencephalogram, snore and myoelectricity of the testee during sleep, and monitoring whether the testee has at least one of small awakening, snore and muscle activity or not during reduction of the blood oxygen saturation parameter value, and step d), repeating the steps a) to c).

Description

technical field [0001] The present disclosure relates to the technical field of sleep monitoring, in particular to a wearable sleep monitor and a monitoring method. Background technique [0002] With the acceleration of the pace of social life, people's social and work pressures increase, leading to a decline in sleep quality. The decline in sleep quality has a negative impact on people's physical and mental health, thereby exacerbating the decline in sleep quality, causing some people to enter such a vicious circle. In short, sleep health has become an issue that cannot be ignored in today's society. There are many reasons for abnormal sleep, and the common ones are insomnia, sleep apnea, and abnormal REM sleep behavior. Clinically, the treatment plan for these abnormal sleep is also very complicated. But in any case, timely and correct diagnosis is the first step to solve the problem, which is very important. [0003] Common sleep disorders include the following: [000...

Problems solved by technology

However, if figure 1 and figure 2 As shown, the conventional polysomnography technology also has the following disadvantages: 1. The steps are complicated, with at least 10-20 electrodes, and the positions are required to be accurate, and special methods are required to prevent them from falling off at night and affect the recording quality; 2. Manual analysis, It is labor-intensive and time-consuming, and sometimes the subjective factors of the analysts affect the accuracy of the results, reducing the comparability with other medical institutions; 3. The inspection must be carried out in the hospital, and the unfamiliar and uncomfortable environment of the ward, as well as electrodes and recording equipment often Affect the natural sleep of the subjects, thereby affecting the diagnosis results; 4. Usually full-time medical staff are required to guard all night, occupying limited beds; therefore, the subjects need to wait in a scheduled time, and the cost is also high
