Problems solved by technology

Although this kind of intelligent sleep monitor does not need to be in direct contact with the human body, which reduces the impact on sleep conditions, it is a passive measurement, and the measurement data is single, so it cannot judge the situation of apnea

Abstract

The invention discloses a multi-sensor heart-lung coupling sleep quality detection system and a detection method thereof. According to the invention, an ultrathin flexible strain sensor and an electrocardiogram sensor are adopted for being easily attached to the body surface of a sleeper and will not generate any discomfort or constraint feel; in a measuring process, the existence of the sensors almost cannot be sensed; the influence on the sleeper is extremely reduced and the state of the sleeper in a sleeping state can be truly reflected. The ultrathin flexible strain sensor is used for measuring the breathing and electrocardiogram signals, and then a heart-lung coupling algorithm is used for comprehensively analyzing the breathing and electrocardiogram signals, so that a quantitative index parameter of the sleeping quality of the patient and the apnea characteristic moment of obstructive sleep apnea syndrome can be acquired; the signals are wirelessly transmitted to a mobile terminal; the volume of the whole system is small; the system can be conveniently used in different sleeping occasions; the multi-sensor heart-lung coupling sleep quality detection system is simple and practicable, high in accuracy, convenient in use and comfortable in feel.

Description

technical field [0001] The invention relates to flexible electronic device technology, in particular to a cardiopulmonary coupling sleep quality detection system and a detection method based on ultra-thin flexible strain and ECG sensors. Background technique [0002] One-third of a person's life is spent in sleep. The importance of sleep to people has been more and more valued by people. The impact of sleep quality and the hazards of sleep diseases are becoming increasingly clear. Apnea is a sleep disorder in which breathing stops during sleep. The most common cause is upper airway obstruction, which often ends with loud snoring, body twitching, or arm flinging. Up to 98% of patients with sleep apnea will snore, usually accompanied by complications such as hypertension, myocardial infarction, myocardial hypoxia, and stroke. Being tired even after getting enough sleep could be a serious health problem. Investigations and studies have shown that the incidence of sleep apnea...
