Non-invasive long-term apnea syndrome monitoring device

Abstract

The invention discloses a non-invasive long-term apnea syndrome monitoring device. A sensor array generates a resistance change signal and transmits the resistance change signal to an acquisition circuit; the acquisition circuit transmits the resistance change signal to a preprocessing circuit; the preprocessing circuit carries out noise filtering on the resistance change signal and then transmitsthe resistance change signal to a microprocessor; an acceleration sensor module collects a turning-over body moving signal and transmits the turning-over body moving signal to the microprocessor; themicroprocessor separates respiration and heartbeat signals in the resistance change signal to obtain a respiration category and a heartbeat frequency and transmits the respiration category and the heartbeat frequency to a cloud platform; the cloud platform judges the sleep depth of a person on the bed within a period of time according to the respiration category, records the time period of apneasyndrome, and draws a sleep quality time diagram according to the number of times and frequency of turning-over and the heartbeat frequency. According to the monitoring device, influence-free heart rate and respiration frequency monitoring can be carried out on the human body, the turning-over frequency of a sleeper can be acquired, and analysis data of sleep quality and the apnea syndrome can beprovided for doctors or monitors.

Description

technical field [0001] The invention belongs to the technical field of acquisition and monitoring of breathing and heartbeat signals, and in particular relates to a non-invasive long-range apnea syndrome detection device. Background technique [0002] Sleep is an extremely important physiological need in the process of human life, but according to the survey, 38.2% of the population in our country has sleep disorders. Among them, sleep apnea hypopnea syndrome (sleep apnea-hypopnea syndrome, SAHS) is a sleep disease that seriously affects people's sleep quality and health. Shock, life-threatening. [0003] Sleep apnea-hypopnea syndrome has a great impact on patients' health and quality of life. Clinical studies have shown that long-term sleep apnea-hypopnea syndrome can lead to arrhythmia, myocardial infarction, hypertension, and other diseases. Therefore, early diagnosis of sleep apnea-hypopnea syndrome is of great significance for the treatment of chronic hypertension an...

(3) Thermal airflow detection method: use the temperature change of the airflow at the mouth and nose during breathing to judge the breathing status during sleep. The advantage of this method is that it is not affected by breathing movement, but the disadvantage is also obvious, and it is easily affected by the ambient temperature.

However, the wristband cannot monitor breathing conditions, and most users find it difficult to accept wearing a wristband to sleep
